Summary

Many patients with previous poliomyelitis develop ‘post-polio syndrome’ (PPS) in which late functional deterioration follows a period of relative stability. The frequency with which PPS can be attributed to clearly defined causes remains uncertain. We reviewed 283 newly-referred patients with previous poliomyelitis seen consecutively over a 4-year period; 239 patients developed symptoms of functional deterioration at a mean of 35 (5-65) years after the paralytic illness. Functional deterioration was associated with orthopaedic disorders in 170 cases, neurological disorders in 35, respiratory disorders in 19 and other disorders in 15. Progressive post-polio muscular atrophy was not observed. Functional deterioration following paralytic poliomyelitis is common, and associated with orthopaedic, neurological, respiratory and general medical factors which are potentially treatable.

Introduction

The incidence of acute paralytic poliomyelitis has been reduced dramatically over the past 35 years by means of mass vaccination campaigns, careful surveillance, and targeting areas in which the ‘wild’ virus persists. In 1988, the World Health Organisation undertook to eradicate the disease by the year 2000.[1] The strategies employed appear to be taking effect,[2] although outbreaks continue to occur.[3] Episodes of vaccine-associated poliomyelitis now account for 75% of reported cases,[4-6) of which two-thirds arise in unimmunized adult contacts of vaccine recipients and the remainder in the vaccine themselves. In England and Wales, there were 21 cases of paralytic poliomyelitis between 1985 and 1991.[7] Five of these were imported and the source of infection unknown, and 13 cases were vaccine-associated, of whom nine occurred in the recipient. The remaining three cases occurred in previously healthy unimmunized adolescent or adult contacts of infants who had received their first immunization. Polio-like illnesses due to other enterovirusess(8-11) account for the remaining cases which occur worldwide.

1996 has been designated ‘Polio awareness year’ (PAY). It has long been known that patients who have had acute paralytic poliomyelitis may, after many years of stable neurological impairment, undergo a progressive functional deterioration. There has been a great deal of interest over the past 10 years in the pathophysiology of this disorder, which has been termed the post-polio syndrome (PPS).[12,137 PPS has been defined as the development of new neuromuscular symptoms at least 15 years after reaching maximum recovery from acute paralytic poliomyelitis.[14] It specifically excludes symptoms related to other neurological, orthopaedic, psychiatric or systemic illness. It has been suggested that progressive deterioration in the function of surviving motor neurones occurs 20 years after the acute infection, leading to the development of new weakness and atrophy which has been termed ‘post-poliomyelitis progressive muscular atrophy’ (PPMA).[15]

Many hypotheses concerning the aetiology of this syndrome have been advanced,[13-16] including immunological mechanisms, attrition of axons overburdened by reinnervation, and ‘normal ageing’ of neurones. These have recently been reviewed.[17]

A previous report from this Unit, however, found that there was a high frequency of additional disorders, such as respiratory, orthopaedic and neurological problems, in patients presenting with late change in function.[18] The frequency with which PPS can be attributed to clearly-defined causes remains uncertain, but it is clear that the development of such symptoms is common.[19] It is important to gain a greater understanding of its pathophysiology, since those patients who developed acute paralytic poliomyelitis during the epidemics of the 1940s and 1950s, prior to vaccination, are now presenting in large numbers with functional deterioration 40 years on.

Methods

The Lane-Fox Unit at St Thomas’ Hospital is a 16-bed unit attended by multidisciplinary respiratory, orthopaedic surgery, neurology and anaesthetic teams, all with a specific interest in the management of poliomyelitis. Owing to close links with the British Polio Fellowship, patients with previous paralytic poliomyelitis have been referred from all parts of the UK for assessment of new or worsening symptoms and changes in function. We have reviewed all newly referred patients with previous poliomyelitis seen consecutively over a 4-year period to the Lane-Fox Unit.

The case-notes of all patients referred for assessment during 1990-1994 were examined by two of us (DK and RSH) using a standardized proforma in order to identify the nature of the functional deterioration, and to identify clinical and laboratory evidence for its cause. The assessment sought clear evidence for the diagnosis of paralytic polio to be made, the nature of stable function, the latency to onset of the functional deterioration and its clinical manifestations. All had been referred specifically to investigate the causation of late functional deterioration. Patients were assessed clinically, and laboratory, electrophysiological and radiological investigations were done when pertinent to the individual case. Patients were therefore not investigated in a standardized way.

Results

During the study period, 283 patients were referred with symptoms of functional deterioration. Three patients (1.1%) were excluded following examination, having been found likely not to have suffered acute paralytic poliomyelitis–one had infantile hemiplegia, one probable hereditary motor and sensory neuropathy (HMSN) type I, and one was found to have glutaric aciduria.[20]

The initial illness

Of the total patient population (n = 280), 41 did not recall sufficient details of the acute infection. In the remaining patients, severe weakness (3 or 4 limbs involved, or severe paraparesis with immobility) occurred in 117 (48.9%) and moderate weakness (1 or 2 limbs only, with mobility retained) in 122 (51.0%). Forty-eight (20.1%) had been ventilated during the acute illne

Following recovery to maximal function, 139 (49.6%) were able to walk unaided, 109 (38.9%) walking with the aid of a stick or crutches and/or an orthosis, and 32 (11.4%) were wheelchair-bound.

Late change in function

Evidence of a deterioration in function was found in 239 patients (85.4%). The mean age of this patient group was 51.8 = 10.9 years. The acute illness had arisen at a mean of 7.9 + 8.4 years. The first symptoms of functional deterioration had occurred at a median of 35 (range 5-65) years after the acute illness. The mean age at the onset of functional deterioration was 42.9 9.9 years.

New locomotor symptoms manifested as diminished mobility in 220 (92.0%) patients, of whom 71 (32.3%) presented with new or increased limb muscle weakness alone, 81 (36.8%) with pain alone and 53 (24.1%) with both weakness and pain. Thus 65% of all patients presenting with late functional deterioration displayed pain as a prominent symptom. Figure 1 shows the distribution of pain in the patients studied. The remaining 15 patients (6.8%) presented with more vague symptoms, such as fatigue and tiredness in association with diminished mobility, but without pain or weakness.

7.9%) patients presented with respiratory symptoms such as daytime hypersomnolence and early-morning headache, of whom four were in type II respiratory failure.

Orthopedic disorders

Degenerative joint disease was common (150 cases, 63%), and was confirmed radiologically in all cases. It was particularly frequent in weight-bearing joints and was more common in weakened limbs than stronger ones (chi? = 11.9, p<0.0001). In patients with weakness on one side only, it ar the paretic side. Sixty-eight patients had severe degenerative disease of the knees, of whom six had bilateral disease (8.8%). Fourteen patients had a joint disorder peculiar to patients with paralytic poliomyelitis, genu recurvatum (Figure 2a). Only nine patients had degenerative disease of the hips. Twelve had degenerative disease of the ankle or foot. Degenerative spinal disease was also common–30 had cervical spondylosis, 25 lumbar spondylosis, and 14 had a worsening of a pre-existing thoracolumbar scoliosis. Five cases of degenerative diseases of upper-limb joints were found, all of whom had ipsilateral flail upper limbs, in which severe osteoarthritis had arisen. In two patients the joint had become dislocated.

The occurrence of severe degenerative joint disease was more common in patients in whom the acute illness had arisen in early childhood, but it was also seen in those whose illness had developed in adulthood. Patients left with severe neurological impairment following recovery were more likely to develop severe arthritis.

Degenerative disease was sufficiently severe to warrant surgery in 34 cases; 14 had patellar bone block procedures (Figure 2b), seven total knee replacements, one knee arthrodesis, two total hip replacements and three subtalar fusions. Seven patients had spinal surgery; in three this was for scoliosis and in three others for cervical radiculomyelopathy; the remaining procedure was a laminectomy for lumbar canal stenosis. A decision to perform surgery was made on an individual patient basis by FWH; the criteria were most commonly if pain was severe, or if the joint was so severely affected as to compromise significantly the independent living of the patient.

One patient was found to have a psoriatic arthropathy. One had a spontaneous haemarthrosis of the knee, one had a ruptured quadriceps tendon and one had tennis elbow. Three patients had rotator cuff syndrome causing pain and upper-limb muscle weakness. Figure 2 X-ray showing genu recurvatum (defined as an angle in recurvatum of> 10°)

Neurological disorders

Complications of orthopaedic disorders were found in 30 patients: 17 patients had cervical radiculopathy, eight lumbar radiculopathy and five had cervical myelopathy (Figure 3), three of whom were treated surgically.

Entrapment neuropathies were found in seven patients: six had carpal tunnel syndrome (in two cases it was bilateral) resulting in reduced upper limb function in five cases. Surgery improved function in all these cases. One patient had an ulnar neuropathy due to compression at the elbow.

Superimposed coincidental neurological disorders (Table 1) were found in 12 patients: three patients were found to have multiple sclerosis, two motor neurone disease (amyotrophic lateral sclerosis) and three inflammatory neuropathies (two had multifocal motor neuropathy with conduction blo had chronic inflammatory demyelinating neuropathy) in addition to polio. Cerebrovascular disease accounted for a progressive functional deterioration in three patients. One patient developed propriospinal myoclonus, possibly arising as a result of compression of the dorsal cord due to increasing scoliosis. The symptoms resolved with the use of clonazepam. Figure 3

Respiratory disorders

Twelve patients presented with respiratory symptoms suggestive of sleep-disordered breathing. In all cases this was confirmed using polysomnography or sleep oximetry studies. Treatment with nasal continuous positive airways pressure (CPAP, four patients) and nocturnal nasal intermittent positive-pressure ventilation (NIPPV, six patients) corrected the disorder in 10 patients; in two it was adjudged not sufficiently severe to warrant treatment aside from weight loss and monitoring.

Four patients presented in chronic or acute-onchronic type II respiratory failure requiring ventilation, of whom one was weaned following treatment of a lower-respiratory-tract infection, and the others remain well on NIPPV.

One patient presented with asthma, another with chronic obstructive airways disease due to smoking, and a third with severe emphysema due to (alpha base 1) antitrypsin deficiency.

Other disorders (Figure 4)

Fifteen patients presented with diminished mobility but non-specific symptoms, predominately tiredness and fatigue. One patient was found to be hypothyroid and improved following replacement therapy. Ten presented with fatigue alone and had symptoms of depression. The remaining four patients were overweight and the change was attributed to increasing obesity.

Discussion

Functional deterioration arising many years after paralytic poliomyelitis has been recognized since 1875[21] and in the first half of this century, several cases were described.[22-24) In 1962, Zilkha reported a further 11 cases in which new weakness developed in muscle groups previously not involved during the acute illness after a latent period of 17-43 years. He suggested that previous poliomyelitis may predispose to the development of motor neurone disease.[25] It has subsequently become clear that there is no increase in the incidence of motor neurone disease following acute poliomyelitis.[26-30]

Estimates of the frequency with which PPS occurs have been variable.[13,15,16) Bradley distinguished between PPMA and other causes of PPS, but this distinction has been largely overlooked by subsequent studies. Electrophysiological studies have shown evidence of continuous and widespread denervation and reinnervation (spontaneous activity with increased jitter and block on single-fibre EMG studies, and fibrillation potentials)[31-33) and muscle biopsy studies have confirmed the presence of denervation, with small angulated fibres, group atrophy and fibre type grouping.[32, 34,35] However, these features have been seen with equal frequency in patients with new muscle weakness and those with stable neurological function.

Howard et al.[18] previously reported a series of 209 patients of whom 163 (78%) developed late functional deterioration due to respiratory factors in 99 cases, neurological signs in 20 cases, orthopaedic problems in 17 cases and general medical factors in eight cases; 31 patients deteriorated due to a combination of factors. Respiratory insufficiency was associated with respiratory muscle weakness, progressive nocturnal hypoventilation due to chest-wall deformity and progressive scoliosis or other precipitating factors stressing critically compromised ventilation. Orthopaedic deterioration was due to progressive skeletal deformities associated with severe underlying disability; scoliosis developed in 94 patients (45%) and was invariable if paralytic poliomyelitis occurred before the growth spurt, and functional deterioration was associated with progressive scoliosis in at least 18 patients. Thirty-four patients had worsening limb function due to cervical spondylosis, osteoarthritis, osteoporosis and contractures.

In a careful prospective study carried out in the Mayo Clinic,[36] a group of 50 patients who had been treated during the acute illness were followed up 30-50 years later; whilst 64% of patients had reported new or worsening symptoms, it was found after comparing examination findings using their structured reporting system (the Neurologic Disability Score, NDS(367) that only 18% had deteriorated functionally. Furthermore, in patients reporting new or worsening weakness, only four patients had truly changed on neurological examination, in all of whom reasonable evidence for the development of a superimposed neurological disorder causing the change had been found (such as diabetic neuropathy). This series has been followed up prospectively;[37] the frequency of symptoms of late deterioration did not change over the 5-year period, and neurological examination findings and test of ma were unaltered. The EMG studies were also unchanged.

The present study provides further evidence to suggest that the aetiology and pathophysiology of functional deterioration after paralytic poliomyelitis is multifactorial. The study did not set out to investigate the prevalence of late complications in all patients with previous poliomyelitis; patients assessed had been referred specifically for investigation of new or worsening symptoms. Owing to the referral pattern from all parts of the UK, however, it is likely that this patient group is reasonably representative of all UK patients suffering late functional deterioration. Although 84% were considered to have undergone a true functional deterioration, the vast majority were found to have orthopaedic problems and/or neurological complications related to these. Whether or not these patients have underlying PPMA cannot be determined, since there are no clear diagnostic electrophysiological abnormalities known. In four patients, no clear cause for the change was ascertained, so it is possible that they do have a progressive muscular atrophy.

Of our patients, 74% had moderate or severe degenerative joint disease; the frequency with which this occurred is much greater than in people of similar age in the normal population[38] and this finding differs from a previous report of the low incidence of osteoarthritis following poliomyelitis.[39] Degenerative changes involved the knees in the majority of patients, and less frequently, the cervical and lumbar spines, the hips and ankle joints. The high incidence of degenerative joint disease in such young patients (mean age 51.8 = 10.9 years) is likely to be due to the abnormal stresses placed upon them by disordered neuromuscular function. Joints disordered, for example, by avascular necrosis of bone, bone dysplasia and sepsis, have a greater incidence of osteoarthritis at a younger age than those with normal joints. Furthermore, degenerative changes progress at a greater rate if misalignment supervenes and if the patient becomes obese. Hence, if weakness around a joint is severe, stability is lost , misalignment may arise and, during weight-bearing, excessive mechanical stresses may be placed on it, leading to early and increasingly severe osteoarthritis.

Why did patients present with increasing weakness in the absence of clear evidence of ongoing denervation and muscular atrophy? Pain associated with degenerative joint disease will lead to restricted movement which may be perceived as muscle weakness, however, not all our subjects had pain (indeed, only 25-35% of patients with osteoarthritis experience pain[38]). Another mechanism of muscle weakness in these patients may be arthrogenous inhibition, [40] in which there is a reflex inhibition of anterior horn-cell firing due to joint inflammation or trauma. This leads to reduced muscle activity and, subsequently, muscular atrophy. Evidence for this comes from both clinical and animal model experiments in which the quadriceps H reflex is suppressed when the joint capsule is stretched with a fluid infusion. Maximal voluntary quadriceps power was reduced by 30-40% following knee surgery.[41] Clearly this weakness may not be appreciated in patients with normal muscle bulk and power, but may have profound effects on the function of patients with denervated muscle.

Concerning respiratory change, previous reports have shown that late respiratory insufficiency was associated with progressive nocturnal hypoventilation due to respiratory muscle weakness, progressive scoliosis and skeletal deformity,[18,42,437 particularly in those who had received mechanical ventilatory support during the acute illness. The present series shows a much lower proportion of deterioration in respiratory function, but a considerably higher incidence of orthopaedic deterioration than in our previous series. This is likely to represent either an earlier presentation of respiratory comp

presentation of respiratory complications with the later development of skeletal problems, or to a change in referral pattern. In summary, of patients with previous paralytic poliomyelitis presenting with late functional deterioration at a median of 35 years after the acute illness, the majority of those who presented with new or increasing locomotor symptoms had degenerative joint disease, and this is likely to be a major factor in their functional deterioration. Neurological complications tended also to be related to degenerative bone and joint disease. Obesity played a role in the severity of the symptoms. No patient presented with clear signs of progressive muscular atrophy with fasciculation, but in 4/280 patients studied, no clear cause of the functional deterioration could be found.

The high incidence of severe joint deformity and loss of function has important implications for the management of these patients. Careful monitoring is needed, and measures should be taken to prevent and retard the progression of degenerative joint disease, including early use and more frequent reassessment of orthoses and callipers, early realignment surgery with osteotomies, and encouragement to avoid the development of obesity.

The present series has confirmed the high frequency of identifiable factors in late functional deterioration in patients with previous poliomyelitis, many of which are treatable, in contrast to PPS. We would urge caution before attributing functional deterioration to the post-polio syndrome or to progressive post-polio muscular atrophy.

What is Polio?

‘Polio’ (or poliomyelitis, infantile paralysis) is a disease caused by three viruses that enter the mouth, grow in the intestines and pass along the nerves into the brain and then the spinal cord. There are 1.63 million American polio survivors.

What damage did the polio virus do?

The polio viruses entered nerves in the brain and spinal cord and took over their ‘metabolic factory’, causing the nerves to stop working normally just to produce poliovirus. During this invasion, the infected nerves could not function and muscles in the arms, legs, chest, diaphragm and throat became weak or were paralysed. If someone had muscle weakness or paralysis, 90% of their motor nerves were affected by the polio virus and at least 50% were killed. The remaining nerves, although damaged, were able to work again and sent out sprouts (like extra telephone lines) to turn on the muscles that were orphaned when their nerves died.

What are Post-Polio Sequelae (PPS)?

Post Polio Sequelae (PPS) – new fatigue, muscle weakness, joint and muscle pain, cold intolerance and breathing and swallowing difficulty – are the ‘sequel’ to having had polio and occur in as many as 80% of survivors of paralytic and non-paralytic polio.

What causes PPS?

PPS are caused by ‘overuse abuse’. Nerves that were damaged by polio and had sprouted have been overworked for 40 years and can no longer take the strain. So too, overworked muscles ache and joints hurt after decades of doing too much work with too little muscle support.

Is PPS a progressive disease?

No, PPS is neither progressive nor a disease. PPS are just the body growing tired of doing too much work with too few damaged and overworked neurons.

Is there any treatment for PPS?

Yes! Since PPS symptoms are caused by the nervous system equivalent of plugging too many appliances into one electrical outlet, polio survivors simply have to unplug some of the appliances. Polio Survivors must decrease the overuse to stop the abuse of their damaged nerves, weakened muscles and painful joints.

What are the treatments for PPS

Polio Survivors basically need to conserve energy to stop blowing their bodies ‘fuses’. Polio survivors must walk less, use needed assistive devices (a brace, crutches, a scooter), stop working before symptoms come on, and plan rest periods throughout the day.

Are treatments for PPS effective?

Yes. The worst case is that patients who stop the overuse abuse will have their PPS symptoms plateau. However, when survivors start taking care of themselves, the overwhelming majority have noticeable decreases in fatigue, weakness and pain.

Isn’t exercise the only way to strengthen weakened muscles?

No. Since PPS symptoms result from too many ‘appliances’ being plugged into an overloaded nervous system, muscle strengthening exercise would be like plugging in a dozen additional toasters. While stretching exercise can be helpful, pumping iron and ‘feeling the burn’ means that polio damaged neurons are burning out. Also, polio survivors typically can’t exercise the way others do to condition their hearts and try to prevent osteoporosis.

What can friends and family do to help?

Polio survivors have spent their lives trying to look and act ‘normal’. Using a brace they discarded 30 years ago and reducing their typically super-active daily schedule is both frightening and difficult to do. So, friends and family need to be supportive of life-style changes, accept survivors’ physical limitations and their new devices. Most importantly friends and family need to be willing, when asked, to do the physical tasks polio survivors probably could do, but should not do any longer. Friends and family need to know everything about PPS and say nothing. Neither gentle reminders nor well-meaning nagging will force survivors to use a new brace, sit while preparing dinner or rest between activities. Polio survivors must take responsibility for taking care of their own bodies and ask for help when it’s needed.

INTRODUCTION

What did it feel like to contract paralytic polio, face lengthy hospitalisation and frequently be left with a disability which was visible for all the world to see? Those who really know are polio survivors but as research findings have shown, survivors rarely mixed with each other after hospitalisation (19) and even now that post-polio has drawn many of them together they find it extremely difficult to talk to each other about their shared past (37,38).

This paper discusses the findings of a survey in which polio survivors were asked to write accounts of their early memories of having polio. These recollections will be compared with the views expressed in the two major sources of information about the polio epidemics that occurred earlier this century. These sets of writings, which I will refer to as the “official” views of the polio experience, are firstly, the books and articles written by health practitioners, mainly doctors, physiotherapists and social workers, who treated patients with polio and secondly, the autobiographies and biographies of people who contracted polio. The official accounts will be shown to differ in a number of ways from survivors’ memories in that they fail to recognise, ignore or distort aspects of the typical polio experience. In fact, they are what could be designated “official myths” of what it felt like to contract paralytic polio. Finally, I will consider how these myths, or social attitudes, influenced the ways in which survivors have coped with polio and post polio syndrome.

HEALTH PRACTITIONERS’ VIEWS

During the epidemics, hundreds of articles and books were written by health practitioners concerning the treatment of patients with polio. What is most remarkable to today’s reader, particularly if he or she had

polio, is how few refer to patients’ feelings and reactions or consider how these might influence treatment outcomes. In fact the articles to which I refer in this paper are quite atypical in that such issues were even raised, however singular the comments that they make may seem today.

Some writers seemed to be aware of patients’ distress but having few solutions to offer confined themselves to comments such as that made by the author of a British textbook on physiotherapy for polio patients written in 1943 (18). Her advice, in a brief paragraph on “patient psychology”, was that, “No crippled individual must be left to indulge in his own thoughts.” At the First International Poliomyelitis Conference held in New York in 1948 one of the speakers acknowledged that, “The psychiatry of polio is the least well understood segment of the problem” (17).

When concern regarding polio patients’ emotional well-being was expressed in the clinical literature it was more likely to be for adults who had contracted the disease than for children. In the lengthy notes on the treatment of people with poliomyelitis that were given to physiotherapy students in New South Wales in the 1950s, the only reference to patients’ feelings was the comment that it “is sad for children” but “well nigh intolerable” for adults (1). In her description of how a hospital in Connecticut coped with a polio epidemic in 1943, Grant, a social worker, described how parents of children with polio were not allowed to speak to a doctor at the hospital from the time of their child’s admission to its discharge (15). The only report they could obtain was from a phone operator during a one hour period each afternoon. Her reports to the parents were phrased as either, “good”, “fairly good” or “serious”. Parents who seemed disturbed and very anxious (they are described as “emotionally immature”) were transferred to a social worker. One such mother wanted to know, “Is Almira still weeping? is she going to die?” The social worker explained that, “weeping was a natural response to separation from parents” and that, “people did not die whenever they came to hospital but usually got better.” In contrast the adult patients and their families were described as “having ready access to the doctor” and being able to discuss “their fears and feelings” with him. There were fewer adult patients but a major factor in the differential treatment of adults and children was probably that health practitioners identified more with patients of their own age.

When references were made in the medical literature to children’s distress, they were often in the context of warning staff of the dangers of responding too sympathetically to their patients. An article in the Journal of Paediatrics in 1938 described a convalescent hospital for Canadian children recovering from polio (16). Nurses working there were given a lecture which emphasised having an “objective” attitude and warned that, “danger lay in allowing one’s natural sympathies to get out of hand.” No visiting was permitted during the month or so of hospitalisation but parents were brought in for a training session prior to their child’s discharge. Here the dangers of too much sympathy and too much spoiling were pointed out. The authors noted that there were some severe cases of homesickness in the hospital. They attributed these to the child’s “abnormal” attachment to its mother or to the child being “unstable”. This article also described the introduction of a program of “wholesome” activities for the children; “good” music, books (not comics), films (“excellent” nature films rather than cartoons which were “too exciting and stimulating”) and various creative activities. Furthermore all children over four years of age were seen by the psychiatrist or social worker soon after admission for, “a five or ten minute chat.. to make the child feel that someone in the hospital was taking a special interest in him.” This article (16) is unique among the writings of the time in that it described steps being taken, however inadequate they might now be judged, to help children cope with hospitalisation.

The lack of concern for child patients’ feelings reflects the health care and child rearing ideologies of the times. In describing the hospitalisation of children in the first two thirds of this century in Britain, Darbyshire wrote that, “the history of paediatric care is one where improvements in child health existed side-by-side with a disregard for the humane side of child and family care which seems almost barbaric

today”(11). The stance of childcare experts such as Truby King, who urged strict adherence to by-the clock routine, and the psychologist J.B. Watson, who advised mothers not to kiss or hug their children or sit them on their laps, supported the regimented and mechanistic care of children in hospital (11). In the 1950s and 1960s the work of reformers such as Bowlby (7) and the Robertsons (29) demonstrated the harmful effects of such maternal deprivation. As part of their campaign the Robertsons produced a film, “A two-year-old goes to hospital” which showed the psychological disintegration of the child. Darbyshire commented that modern audiences find it hard to believe that health practitioners once considered such distress acceptable. At the time however there was quite extraordinary opposition by doctors and nurses to the film and to reformed visiting hours(11). It was not until after the publication of the Platt Report, “The welfare of children in hospital” in 1959 that very gradual changes were introduced in British hospitals. Even in 1965 two paediatricians published a letter from a mother in the Lancet in which she described how her three year old, who had never been separated from her mother, was admitted to hospital for a tonsillectomy (22). The child began crying when the mother had to leave. The mother was not allowed to visit on the day of surgery although the child was haemorrhaging but was told she could visit late the next afternoon. When she arrived she was told her daughter had collapsed, the doctor was doing everything possible but she would have to wait. “Although I was there I couldn’t see her even when she was dying. They took me to see Dawn but it was too late for my love to do its work.”

The perceptions of doctors of those times seem extraordinary when juxtaposed with such accounts. Barraclough wrote an article on the hospitalisation of children in the American Journal of Psychiatry in 1937 in which he extolled the benefits of the children’s ward where the “patient is surrounded by an atmosphere of neutrality” (5). He noted the benefits of not having anxious parents or Friends nearby. The new patient, he said, “is impressed by the calm and unemotional atmosphere… Adjustment does not take long, a day or two at most”. All was forgotten once children go home he opined.

Opposition to more humane care of children in hospital was pervasive. Davis, a sociologist, wrote a book, “Passage Through Crisis”, which described his observations over a two year period of 14 American children who contracted polio in the mid 1950s and their families (12). Davis was struck by “the callous, depersonalised and deadeningly routine treatment in the hospital.” He described health practitioners’ interactions with parents as, “brusque, noncommital… even at times condescending and indifferent.” Davis also commented on the fact that younger children often thought that they had contracted polio as a result of a sin or transgression they had committed. Yet despite these observations, Davis agreed with the views of the medical establishment, that the adoption of the changes being advocated by reformers, such as the Robertsons, would threaten and interfere with the goals of medical treatment.

A case study published in 1930 in America (24) is believed to be the earliest reference in English to the psychosocial effects of having polio (30). In it Newell described a set of triplets consisting of identical twin girls and a boy (24). When they were two years old, one girl and the boy contracted polio and the

latter died. The father blamed the girl for infecting his favourite child and her mother said that she “forgot” to visit her while she was in hospital. Both parents favoured the ablebodied twin. When studied at 14 years of age, the twin who had had polio was found to lack self confidence, to feel inferior to, and jealous of, her sister and to be less cheerful and responsive toward other people than was her twin. Newell’s reason for writing up the case was his amazement at the fact that twins, who were identical genetically, could differ in personality due to social factors (the parents’ differential treatment of the twins). However the author could not accept that the polio twin’s poorer performance at school could be attributed to social factors and the fact that she had had to learn to write with her left hand due to paralysis of her preferred right hand. He concluded that the virus must have damaged her brain. Nor did the writer speculate as to how other children growing up with a disability might be affected by their social environment. The social model of disability (as encapsulated in the International Year of the Disabled

slogan, “Your attitudes are our greatest handicap”) was half a century away.

Two reports of follow-up surveys of people who had contracted polio one and four years previously were published in the New England Journal of Medicine in 1932 and 1935 (3,4). The author concluded that for those who “completely” recover, “the disease seems to have no darker memories than of an attack of measles.” However 30% of those with residual paralysis were classified as “emotionally maladjusted to their handicaps.” Five individual case studies of children were reported. The children’s problems were attributed to their being “oversensitive” about their disabilities, never to the difficult situations with which they had to cope.

In 1944 a follow-up survey was conducted of 100 children who had been studied by Grant during the Connecticut epidemic (10). These children had all returned home. The researcher expressed “surprise” on finding that 38% of the children had serious enough psychological problems, “for the parents to discuss them with us”. The author, a social worker, concluded that polio, “leaves many scars on those who were affected besides the obvious physical handicaps. If this fact is recognised and the children and parents are given assistance at the time of the acute illness and during the convalescent period, the future of these children may be less impaired.”

Greater recognition of the stress polio patients experienced began to emerge in the medical literature toward the end of the epidemics. An article that appeared in the American Journal of Physical Medicine in 1952 (13) warned nursing staff that their management philosophy of not “spoiling” children with polio in reality increased their anxiety, dependency and hostility. The author counselled that newly admitted patients should not be left alone in isolation wards and should be given a nightlight. Nurses were advised to make rounds frequently and not to remove patients’ call-bells because they were being used excessively. In fact, the author said, once patients established that staff could be trusted to respond to their needs they would reduce their demands markedly. Nurses were encouraged to allow patients to voice their fears and to answer their questions.

An insight into the mystification of patients which was prevalent at the time is found in the notes issued to physiotherapy students in New South Wales in the 1950s (1). The author advised against giving patients information, stating that it is, “bad practice for a physiotherapist to teach a patient the names of muscles and discuss their respective gradings” as ” most orthopaedists naturally do not like a pseudo-learned discourse from the patient.”

Late in the epidemics several articles discussed the severe stress experienced by polio patients who required respiratory support (23,28,31). Some patients were reported as experiencing hallucinations when placed in an iron Lung. Being weaned from respiratory support was described as particularly frightening. In 1961, in an article in the Archives of General Psychiatry (35), Visotsky et al. posed the question, “How is it possible to cope with such powerful, pervasive and enduring stresses as those involved in severe poliomyelitis?” The authors went on to describe their survey of the coping strategies they had observed adult polio patients use during their lengthy hospitalisation. Examples cited included keeping their distress within manageable bounds, maintaining their relationships with their families and friends, continuing to hope and maintaining their feelings of self-worth. Here for the first time we see the emphasis changing from speculation as to what is wrong with survivors who have not cheerfully accepted their disability, to approbation that polio survivors have the resilience to cope. Again this more empathic stance was directed at adult rather than child patients.

But by now the epidemics were almost over. There is little evidence that these new insights influenced Australian practitioners. I have found no reference to the psychosocial aspects of contracting polio in the many articles which appeared in Australian medical and physiotherapy journals at that time.

In summary, health practitioners at the time of the epidemics attached little importance to the feelings of patients who contracted polio. They grossly underestimated the degree of distress that people, particularly children, experienced. In essence the medical myth was that : Contracting polio is not very upsetting for children; they soon get over any distress unless they are spoilt.

POLIO BIOGRAPHIES

Many polio survivors wrote autobiographical accounts about contracting polio and other people, often their parents, wrote their stories. Recently Wilson analysed the themes in 50 such narratives which he described as providing, “a window into both the experience of polio at midcentury and the ways in which those who had polio struggled to make sense of the experience” (41). Wilson found that virtually all the stories were written as accounts of achievement and triumph over adversity. He identified two major themes in the stories, which he described as the themes of recovery (or work) and redemption (or grace). He likened these themes to the early Puritans’ notions of work and grace. For the Puritans, doing good works was not sufficient to gain eternal salvation. God’s grace was also required.

Polio biographies typically described the survivor making a contract to work hard to recover. Such an agreement which was, “sometimes tacit and often explicit between patient and therapist was to push until the absolute physical limitations had been discovered” (41). For example, Leonard Kriegel in his autobiography described polio as, “a disease battled by being tough, aggressive and decisive. And by assuming that all limitations could be overcome, beaten, conquered” (20). Bea Wright’s biographer wrote that, “Polio was the most tangible enemy she had faced yet and she intended to give it ‘no quarter'” (9). Arnold Beisser’s physiotherapy eventually became counterproductive when his muscles were badly overstretched but his therapists believed so fervently in hard work that they were unwilling to stop the treatment. They considered that, “if you were not improving in the way you hoped, it was simply that ‘you didn’t want it enough'” (6). Larry Alexander wrote in his autobiography that, “You can do it. Determination and guts and don’t give up” (4).

However in all the biographies, patients’ progress eventually slowed or halted. Feelings of despair and depression of being, “nothing but a cripple” were experienced. It was now that what Wilson described as the experience of grace occurred, enabling almost every writer to, “achieve some level of understanding, some sense of acceptance and resignation, or some faith in God’s ultimate purpose as a means of coming to terms with their remaining disability” (41). For example, Roger Winter became a Christian and concluded that, “polio had been a blessing and a source of strength” (42). Larry Alexander found a new faith in himself, “a new optimism, for the first time I began to explore the question of survival, of adapting to what I had, of living with my paralysis” (4).

How accurately do these accounts reflect the typical polio experience? Wilson commented that only one narrative dwelt on negative feelings such as rage, anger and hatred and even this writer eventually accepted the role of the “good handicapped person.” However he noted that some of the writers briefly referred to fellow patients who failed to make progress or to adjust to their disability. None of these people wrote autobiographies, perhaps because such stories were not acceptable. Wilson quotes a book editor of the era who wrote that, “if a person with a disability expresses his bitterness deeply or with any sense of personal tragedy, he risks alienating the non handicapped. As long as the handicapped individual is cheerful and lighthearted, he is like the jolly fat boy, usually accepted” (41).

Interestingly, several of the authors whom Wilson discussed wrote their autobiographies or produced further accounts of their disablement in the late 1980s when post-polio syndrome had been well publicised in the United States. Yet in none of these later writings by Beisser or Kriegel have I seen references to

post-polio syndrome although one gets the impression of the authors’ deteriorating health. Perhaps if the battle to triumph over polio gave meaning to their life stories then post-polio made demands that called for too radical a revision.

The sociologist Irving Zola (who had both polio and post-polio syndrome) believed that few biographies of people with disabilities, “tell it like it is” (43). Indeed he considered that, “to a marked degree certain aspects of disabled people’s lives have been inaccessible to themselves.” He argued that one of the reasons for this inaccessibility is that to be successful in mainstream society we have to downplay our disability and its effects on our lives. In fact we may even deny these; for example saying, “I never think of myself as disabled” and taking it as a compliment when others make a similar comment. A further reason, according to Zola, is the lack of close contact with others who are disabled. Most people with disabilities live in families of ablebodied people and rarely encounter people with similar experiences to their own. Even when they do so, the strong social taboo of not talking about your disability (because that constitutes being sorry for yourself) usually operates. Authentic accounts of disability according to Zola, “say things many won’t like, use images that may shock or repulse” (43).

In summary, survivors’ biographies downplayed the distress and stress associated with having polio. Their message was that through commitment to exhausting physiotherapy programs many of the effects of polio could be overcome. With acceptance of any residual disability all would be well. (Never mind negative community attitudes toward people with disabilities, lack of access etc.). In essence the myth that polio biographies gave rise to was: Ignore your distress. Hard work and cheerful acceptance will overcome polio.

SURVEY OF POLIO SURVIVORS’ MEMORIES

Method

In earlier papers I have described the procedure and some of the findings from a five year follow-up mail questionnaire survey of people with post-polio syndrome conducted in 1993 (37,38). This paper presents further findings from the survey. At the time of follow-up the mean age of the 176 participants was 57 years (range 33-77 years). Their median age at the onset of polio had been 8 years with a range of one month to 35 years. The median length of time spent in hospital when they contracted polio was 11 months. Twenty recalled being placed in an iron lung.

The aim of the present study was to investigate the feelings and experiences reported in survivors’ early memories of having polio in order to understand what people typically experienced. How do survivors’ memories compare with descriptions of contracting polio which appeared in the medical and biographic literature of the time?

A second aim was to investigate whether two factors, age at onset of polio and being placed in an iron lung, influenced the feelings and experiences reported in survivors’ memories. As discussed earlier, the medical literature implied that adults and patients in iron lungs had a particularly stressful time.

Participants in the survey were asked to, “Describe the earliest memories you have of having polio. What are the dearest parts of these memories? What are the strongest feelings in these memories? What did you think and want to do at the time?” It was suggested that survivors might prefer to take their time to think about the question, “before returning to the questionnaire to write your thoughts down”. If respondents had been too young at the time to remember the onset of polio they were told they could include in their accounts memories of what they had been told. Only eight people taking part in the survey failed to record

their memories. Thus the results are based on a sample of 168 survivors (95% of the group). The length of people’s accounts ranged from one sentence to 748 words.

The feelings that survivors expressed in their memories were identified by applying content analysis scales devised by Gottschalk and Gleser (14) and Westbrook and Viney (33,34,39,40) to their accounts. The validity and reliability of the scales have been demonstrated. The scales that were applied to respondents’ accounts measured their feelings of anxiety, depression, anger, happiness, helplessness, efficacy, and experiences of benign and negative social interactions. When measuring anxiety with these scales it is possible to identify seven sub-types of anxiety. These indicate the focus of the person’s anxiety viz. death, mutilation, separation, guilt, shame, diffuse or non-specific anxiety and uncertainty. Tables 1- 4 give examples of the types of references in a person’s memories which would indicate a particular feeling and examples from survivors’ accounts. It should be noted that some of the examples cited would be scored on several scales, e.g. the example given for mutilation anxiety is also an example of a negative social interaction.

The research was based on the assumption, which is supported by a range of research findings, that the memories and associated feelings recalled by respondents have particular salience for them (8,14). Terr, who worked with children involved in traumatic events, found that years later, those as young as 28 months at the time of the trauma, could accurately describe some of its aspects (32). She reported that when children, even younger than this, encounter trauma, “the child ‘burns-in’ a visual memory of it, sometimes later becoming able as the years go by to affix a few words to the picture. These few words, however, represent true verbal remembrances of a fixed mental picture” (32).

Results

The findings of my survey were as follows. The feeling most frequently found in survivors’ memories was anxiety. Overall 84% of respondents expressed one or more types of anxiety in their narratives.

Table 1 shows how many accounts contained the various sub-types of anxiety. The sub-type of anxiety most frequently expressed was mutilation anxiety which occurred in three quarters of survivors’ recollections. Separation anxiety was expressed by 58% of respondents, diffuse, or nonspecific anxiety by 37%, uncertainty by 35%, shame by 30%, death anxiety by 21% and feelings of guilt by 19%.

After anxiety, depression was the most commonly expressed feeling; 70% of survivors made statements indicating depression. Anger was present in 45% of accounts. Of all the feelings and experiences investigated, happiness was the least frequently reported, occurring in only 17% of accounts (see Table 2). Happiness was rarely described as occurring in hospital.

Feelings of helplessness, of life being out of control, were found in over twice as many recollections (68%) than were feelings of efficacy, or being able to influence events (33%) (See Table 3).

Negative social interactions were described in 57% , and benign interact ions in 56% , of accounts. The scale measuring benign interactions includes both highly positive and neutral social interactions; in other words any social interaction that is not viewed negatively. It is noteworthy that negative social interactions, in which people were described as harming or upsetting the survivor in some way, were mentioned by fractionally more respondents than were benign interactions. When describing life events, people typically mention more benign than negative interactions. For example, in previous research I asked women who had recently given birth to describe their memories of pregnancy and childbirth; 98% of them described benign social interactions while only 32% spoke of negative ones.

The impression survivors’ memories give of the typical polio experience is of very anxious, depressed, helpless, often angry people. They had been separated from their families, were cared for by staff who were likely to treat them harshly and they had few sources of pleasure or the ability to influence the events that had overtaken them.

The overwhelming conclusion to be drawn from these analyses of survivors’ memories, is that the early experience of polio was almost unrelentingly negative and profoundly distressing. This picture bears little resemblance to the medical myth that children experienced little upset and soon adjusted to hospital. Some of the participants in the survey expressed more concern with the plight of younger patients than is apparent in the clinical writings of the time. One survivor wrote, “One dear little dark haired beauty of two years came into isolation and we watched as she was reduced to a little, still heap with only little noises left.” Another commented, “I saw so much cruelty and sadness. I sometimes think of all the children in the hospital who were damaged for life.”

The fact that feelings of efficacy, of being able to influence events, were less than half as frequent (33%) as feelings of helplessness (68%) does not support the biography myth that most survivors endorsed the belief that through hard work and acceptance one can triumph over polio. Few memories mentioned survivors applying themselves to physiotherapy with the vigour and enthusiasm described in the biographies. When survivors’ memories concluded with an attempt to evaluate their experiences some were positive though never triumphful, e.g. “On the whole, pain included, I have much to be thankful for”, “Polio was never used as a reason for not ‘giving something a go’, an attitude that helps me to this day”, “I believe I have done more with my life because of polio”. Two respondents referred to God having his reasons for their disablement. One of these survivors is looking forward to heaven where, “I’m going to run fast for the very first time”. More frequently survivors’ evaluative summings-up of the polio experience were sombre, e.g. “Counselling would have been helpful (in hindsight). Many people with polio have been scarred emotionally”, “At times I wanted to die, and sometimes now and again I wish I had”, “For 30 years, until I faced everything and did my belated weeping for the ‘little girl’, Northfield was my hell, my concentration camp”.

In contrast to the medical views at the time of the epidemics, the feelings expressed by people who were younger when they contracted polio were remarkably similar to those of older cases. Age at onset of polio influenced the expression of only two types of feelings in people’s accounts (See Table 5). Older children and adults were more likely to report death anxiety and less likely to feel guilt than were younger children who often attributed their illness to God punishing their bad behaviour as Davis found in his study (12).

The views expressed in the medical literature concerning the severe stress of being in an iron lung received some support from the results of the present survey. Survivors who had been placed in iron lungs were significantly more likely than other respondents to express four negative feelings; death anxiety, diffuse or non-specific anxiety, uncertainty and anger (See Table 6). One respondent wrote, “I remember I was gasping as one does when one has been crying desperately. Later they told me, ‘We are putting you in a respirator’. I remember dreaming respirators raining down on me like packs of cards in Alice and thinking they were coffins.” Another recalled, “The whole time (in children’s hospital) I felt mortified and worthless. I remember the grey walls in the room where my iron lung was. No one spoke to me. The nurse didn’t want to get too close to me. These memories are horrible.”

Overall these findings indicate that the reality of the polio experience was for most survivors very different to that portrayed in the official myths at the time of the epidemics.

IMPLICATIONS FOR SURVIVORS

The acceptance of the official myths at the time of the epidemics resulted in the real polio experience not being documented or widely acknowledged. Survivors rarely spoke of their experiences. When confronted with the official myths (that being hospitalised with polio was only upsetting for spoilt children and that survivors, such as the polio biographers, had cheerfully accepted their disabilities) individual survivors thought that they themselves must be inadequate because they sometimes felt distressed and found it difficult to cope. So they kept silent even with each other.

The fact that survivors were deprived of their common history, influenced how they and their families coped with their disabilities, both before and after the advent of post-polio syndrome. I will invite you to discuss this, after mentioning some examples of these effects that were apparent in survivors’ recollections. Obviously not everyone had all these experiences but the following themes appeared in a sizeable proportion of survivors’ accounts. These included:

Survivors’ families did not discuss polio. Some survivors said that polio was never mentioned within their families. As one wrote, “The word polio was banished from family conversation.”

Survivors do not talk about their feelings. Although many respondents to the survey spoke of the clarity of their memories, e.g. “I remember every little detail of those terrible times in 1946”, they said that they have never or rarely talked about them.

Survivors judge themselves harshly. Some respondents spoke of the role models they were presented with, such as Marjorie Lawrence, President Roosevelt or local identities who coped bravely with polio, e.g. “I was always compared to Judy so I had an example of how to be brave, because she never complained.” Survivors felt that they had to prove themselves, e.g. ” I think I have lived the rest of my life trying to prove I am not worthless.” Not only were many survivors intolerant of any perceived weakness on their part but none acknowledged, or even seemed aware of, their own courage and resilience in coping with polio.

Survivors ignore the needs of their bodies. As we now know, overuse of muscles and joints compromised by polio has contributed to post-polio symptoms (26) but survivors recalled ignoring fatigue and muscle weakness, e.g. “I now know I should have been taught to ask for help and not overtire myself. The message was, Try again and you can do it and I did.” Such coping strategies are the antithesis of those required in the management of post-polio syndrome but it is very hard to change the attitudes of a life time. The fatigue of chronic fatigue syndrome (CFS) has been shown to be similar to that of post-polio syndrome. In another research study, in which I compared the coping strategies that polio survivors and people with CFS use to cope with the symptoms of their illnesses, I found that polio survivors were significantly more likely to attempt to maintain their previous activity levels (38).

Survivors lack awareness of their pasts’ influence on the present. The typical polio experience involved a child suddenly becoming ill and paralysed, being separated from their loved ones and placed in a strange and often harsh environment. Seven percent of recollections described behaviour by nurses which would today be labelled child abuse. For example, one survivor recalled that as a four year old, “On one occasion after I soiled my bed (being totally paralysed in arms and legs) the sister threw me in the canvas remedial pool and left me for a considerable time as punishment. On another occasion she wheeled my bed onto a balcony and warned if I ‘dared to blink’ the bed would go over the edge. They were doing repairs and the railing was removed.” I did not classify as child abuse many other examples of harsh treatment such as the nurse who told a two year old that, “If I cried I wouldn’t be allowed to have visitors.” Many survivors spoke warmly of their parents, e.g. “I am now thankful my parents treated and accepted me, and polio, in such a positive way” but 44% of respondents described being cruelly rejected by their parents, particularly their fathers, who were not able to accept a “crippled” child.

Such experiences are described today as abuse or trauma and people would be expected to exhibit symptoms of post-traumatic stress. Due to the acceptance of the official myths of the time, survivors rarely connect present feelings and beliefs with their past histories. One such legacy from the past is lack of trust that the people in our lives such as family and friends will remain with us or provide support if our disability increases. Another legacy is fear of hospitals and wariness of health practitioners. Sometimes quite specific situations trigger fear reactions because they remind us of the past. One survivor commented, “all my life I’ve had an uncomfortable feeling when I was in a room illuminated by only a ceiling light. Only a couple of years ago it dawned on me that it all goes back to that hospital room and its single bulb in the centre of the room” (27).

THE NEED TO SPEAK OF OUR HISTORY

I have spoken previously (37) of the need and benefits (25) of telling our history whether to a professional counsellor, an empathic friend or privately writing an account. Some survivors in the survey related that they had done this. Several, “saw a psychiatrist who helped me.” Another, “tried to purge myself” of her negative feelings about the past. “I sat down each morning and wrote a journal. There is nearly a book full of it. I finished, closed the book and have never opened it again. I still have the book and feel some of the purging helped me.” Others thanked me for providing them with the opportunity of responding to the survey. One wrote, “Suddenly the sluice gates are open. Here I am telling my story for the first time.

Over the past two years the American based post-polio internet has provided a forum in which participants have gradually begun to share their early memories. Many have commented on how difficult this has been. One woman said, “To those with PPS, like me, who had never before in my whole life talked about my polio; to risk boring others with the mundane details of my story took every little tingle of courage I could muster. A healing act I might add”.(27) One new participant accused members of the group of “wallowing” to which another responded, “Wallowing? Watch us for a bit and notice the grief that’s been worked through … (there was) no one who’d been there to share with, those isolated times in hospital as a child, the fear, the pain .. and now the shock and disbelief of new symptoms. We are first ditching grief that has been carried a lifetime … notice the nurturing of fellow polio survivors and lastly the joy in having connected to others in the same condition” (27).

The poet Denise Levertov (21) wrote in her poem “To speak”:

To speak of sorrow

works upon it

moves it from its

crouched place barring

the way to and from the soul’s hall.

Where Do We Go From Here

POST-POLIO SYNDROME: WHERE DO WE GO FROM HERE?

Mary T. Westbrook, PhD

e

Paper presented at the final plenary session of the Australian International Post

Polio Conference, Sydney, November, 1996 Lincolnshire Post-Polio Library version by kind permission of the author

Mary T. Westbrook, PhD Department of Behavioural Sciences Faculty of Health Sciences University of Sydney

The task I have been assigned in this final session of the Australian International Post-Polio Conference is to present an overview of our activities over the last three days. I have attended previous post-polio conferences in Australia and overseas and I consider that this conference is the best in which I have ever participated.

As usual the major focus of this conference has been health care for people with post-polio syndrome. We have had excellent information and advice from our international speakers, Dr. Yarnell and Dr. Dean. Australian health practitioners from a range of professions such as medicine, physiotherapy, occupational therapy, speech pathology and podiatry have presented lectures and workshops.

An interesting innovation at this conference was that polio survivors were more involved in the presentation of health care sessions. In two of the workshops a health practitioner and one of their PPS clients gave the two sides of the story; an orthopaedic surgeon and his client discussed hip replacement surgery and a speech pathologist and her client discussed swallowing problems. There was also a workshop in which attenders described what they had found helpful in dealing with post-polio symptoms.

A major innovation at this conference was that while there were five plenary sessions there were also four sessions during which four parallel workshops were presented. While this presented dilemmas of choice it also meant that each workshop session, which lasted 75 minutes, could present a topic in depth and allow more opportunities for participant involvement than is possible in plenary sessions. Interestingly, 11 of the 16 workshops were presented or co-presented by polio survivors. Although they were often speaking in a professional role they really understood the experience of post-polio and this enhanced their presentations.

It was apparent from reactions in the health care sessions that a major concern of survivors is accessing health practitioners who are knowledgeable about PPS. Some support groups have been active in

collecting and passing on information about such practitioners to their members. There is clearly a need to increase the clinical knowledge of health practitioners regarding PPS and to encourage research in the area. We need to liaise with health professional schools regarding the inclusion of PPS in their curricula. We should suggest that they encourage some of their honours and post-graduate students to do research in the area of PPS. Such tasks seem daunting but remember that the post-polio clinic at Prince Henry Hospital and the associated research program have their origins in the efforts of the NSW Post-Polio Network. One inducement that we can provide is willing research subjects.

Another innovation which added to the success of this conference was the wider perspectives from which the PPS experience was explored. The conference had an international perspective both in terms of speakers and participants from overseas. These visitors helped participants to view disability from a cultural perspective as did the workshop by Gayle Kennedy, an Aboriginal Australian who contracted polio. Videos on the situation of people with disabilities in other countries were shown including one on the elimination of people with disabilities during the Third Reich. An historical perspective was introduced by sessions which explored attitudes in Australia at the time that we contracted polio and how such attitudes shaped our initial treatment and our future lives. Disability rights and the problems of women with disability were discussed.

One overwhelming impression I have from the conference is that we polios are opening up with each other in ways that did not happen in the early days of our support groups. We are acknowledging that dealing with PPS is difficult. We still too frequently downplay our problems and criticise ourselves for not coping more effectively. As one participant said, we need to learn to ask for help and to say ‘No’ to demands that overtax us. One of the main messages of this conference has been that we need to be caring of ourselves and that we can gain much through mutual friendship and support. I recently read the following comments by Kitty Stein (1) who has multiple sclerosis. They also apply to polio survivors. She says that we need to nurture ourselves or as she expresses it, ‘to develop a nurturing voice’.

Acquiring a nurturant voice means entering into a mutual, loving relationship with yourself. It means being empathic with yourself when things are hard. It means tolerating your shame,

soothing yourself when you’re disappointed, off balance or disoriented, uncertain, and so on. It means giving yourself enough time to adapt, protecting your use of energy so that you can do the things that are important to you. It means providing limits for yourself in an understanding tone. It means appreciating that you are more than your illness. It means being able to reach out for and receive collaborative support when you need it. It means appreciating all that you do for yourself that you wouldn’t have to do if you weren’t chronically ill or disabled. It means advocating for yourself both internally and externally when needed. And it means understanding how difficult it is to do all this and being supportive with yourself when you make mistakes and get upset. (pp. 117-118).

Finally, I’d like to talk about where we’re at, what we have achieved, before we rush on in typical polio style, to where we are going. Earlier this year ‘New Mobility‘, an American magazine aimed primarily at people who have a spinal cord injury, ran an editorial entitled ‘Polio, PPS and Beyond’ (2). In it the editor, who has a spinal cord injury, wrote:

The polios, above all else, were our (disabled people’s) pioneers. We owe them our lives. They survived into a strangely divided land that was, by definition, friendly to them and hostile to their disabilities. Instead of caving in, they invented rehabilitation, independent living and disability rights. Now they’ve survived into the bizarre world of post-polio sequelae, and they’re faced with national indifference. Will they do as well?

The polios once showed us – the nonpolio crips – how to live in the world with a disability. They showed us what it is to be disabled and proud and to survive and sometimes have a good time doing it. Now they may teach us how to grow old with our disabilities.

Long live the polios (p. 6).

Some health practitioners regard PPS as the last rattle of a group of dinosaurs about to depart in the last ark off the rank. But our struggles are beginning to have significant effects on rehabilitation theory and practice. As you know post-polio symptoms have two major causes; the neurological changes that are unique to PPS and the overuse of compromised body systems interacting with the ageing process. As a result of publicity about PPS this second set of late effects is now being recognised as occurring in a wide range of disabilities previously considered to be stable e.g. spinal cord injury, cerebial palsy, spina bifida. congenital and early amputation. In 1995 Dr. Christopher in his presidential address (3) to the American Academy of Physical Medicine and Rehabilitation called for a new life-span approach in rehabilitation which incorporates this late-effects model. The late-effects model is beginning to be applied to disabilities acquired later in life such as stroke and those long recognised as progressive such as diabetes and multiple sclerosis. Indeed this late-effects or life-span perspective is now considered relevant to all disabilities. Okamoto and Yang (4pointed out that, ‘Ageing with a disability begins at the time an individual acquires a disability and ageing infers a dimension of time to the disability that is changing not static as once believed’ (p.2). People ageing with a disability have been described (as we know from experience) by the American Congress of Rehabilitation Medicine (5) as ‘orphans’ in the health care with ‘no system of post rehabilitative primary care, acute care, or long-term care that is responsive to the particular constellation of health care problems commonly experienced’ (p.58).

The recognition of the late effects of disabilities has led to some critical evaluation of initial rehabilitation. Mottos such as ‘No pain no gain’, ‘Use it or lose it’ and ‘Independence at any price’, which encourage super-crip behaviour are beginning to be questioned and replaced by mottos such as ‘Conserve it to preserve it‘ (6, 7). A handbook for consumers entitled, ‘How to Live Longer with a Disability’ has also been published (7). One of its authors has spinal cord injury and the other, of course, has post-polio syndrome.

LONG LIVE THE POLIOS!

New book furthers polio hypothesis

Post-Polio and Post-M.E.

New book furthers polio hypothesis

Jane Colby

The CFIDS Chronicle – Fall 1996

A CFIDS activist, Jane Colby is on the UK National M.E. Task Force, gives lectures and media interviews and regularly advises UK CFIDS charities. In April 1996 she and TV personality Esther Rantzen launched their M.E. Children’s Charter for the UK organisation Action for M.E. Her Children’s Charter and other information about CFIDS/M.E. can be found on her website at http://www.jafc.demon.co.uk

The following is an excerpt from the recently published book M.E. The New Plague by Jane Colby, a former school principal turned writer and researcher. The book, reviewed on page 55, uncovers strong evidence that myalgic encephalomyelitis (M.E., the British term for CFIDS) is a type of polio which has, by historical accident, been given another name. Jane warns that we are repeating the mistakes of the past, which have led to further illness in polio survivors decades later. She also includes a risk factor list, survivors’ lifestyle checklist, schools guidelines, comparisons of M.E. with school phobia and a chapter on psychological survival. Jane interviewed numerous experts including Dr. Richard Bruno, a post-polio researcher at the Kessler Institute in New Jersey. To order M.E. The New Plague, see item #3240 on page 63.

By altering the population’s resistance to a particular organism, we alter the balance of infectious agents in the environment. Most of us are resistant to polio viruses 1-3 through vaccination. But we have not been immunized against the many other polio-related viruses [such as Coxsackie].

It is therefore not surprising that since the late 1950s the incidence of M.E. has risen and risen, and experts predict that it will turn out to be the commonest neurological disease of the 20th century. Indeed, it has already been estimated that the total M.E. cases in 1987 equal the 1952 polio cases. By suppresing the spread of these enteroviruses we have opened the door to the rest.

It can be observed through case histories that, just as we see post-polio syndrome 30 years after initial polio infection, so we are seeing what I have called “post-M.E.” as well, in people who got M.E. as youngsters.

A proposition from the Nightingale Foundation in Ottawa is that, in fact, M.E. and post-polio are one and the same condition. What has arisen is:

“Two new diseases with different names, with different degrees of acceptance and exactly the same set of symptoms at exactly the same time. It is unrealistic to believe that we are dealing with two different disease processes and two different causes.” [1]

Alternatively, and because of the difference in the detail of symptoms between post-polio people and those with M.E., we might be able to say that M.E. in youngsters is the equivalent of acute polio in youngsters, and that post-M.E. (in sporadic adult cases) is the equivalent of post-polio, developing years after the original infection.

If M.E. and polio are enteroviral conditions, simply variations upon one another, then the “sequelae,” or later complications, are post-enteroviral conditions. This has far reaching implications. Around 90% of polio survivors have gone on to develop post-polio syndrome. It has been predicted that this will eventually rise to 100%. [2]

In addition, those children who, back in Iceland in 1948, developed M.E. (then called Iceland disease) were followed up decades later and the majority still had symptoms.

[Post-polio expert] Dr. [Richard] Bruno points out that physical over-activity is the biggest cause of post-polio symptoms. [3] (See Dr. Bruno’s “Fainting and Fatigue” in the Spring 1996 Chronicle, page 37.)

What are we doing to our teenagers with M.E. when we force them back to school, deny them home tuition and tell them to exercise as a form of therapy?

We know that muscle cells in M.E. have faulty “battery” mechanisms and that energy cannot be readily regenerated. The aerobic/anaerobic cycles are disrupted, so that if we overwork muscles affected by M.E., the fibers that can work without oxygen, and that are there for use in emergencies, get over-used, potentially causing damage.

It is well-known amongst people who are trying to get over M.E. that exercise, often undertaken early on in the disease in attempt to get fit again, can make them a great deal worse. This is partly because the muscles are not able to function like healthy muscles. But knowledge of the behavior of enteroviruses goes even further towards explaining why this should be.

Right back in 1970, it was shown by Gatmaltan, Chason and Lerner that when mice infected with Coxsackie B3 were forced to swim in a warm pool, the virulence of the virus was drastically augmented. In fact, viral replication was augmented 530 times. This did horrendous things to the animals’ hearts. We all know that to play squash with the flu can lead to heart attacks. Much the same danger can be courted by undertaking hard exercise with M.E.

In 1988, Reyes and his colleagues exercised mice suffering from Coxsackie B3 myocarditis — inflammation of the heart muscle caused by the virus. They showed that the effect of exercise on the production of the neurohormones which regulate immune response and inflammation led to an increase in susceptibility to Coxsackie virus infections — the host response was altered in favor of the virus.

Roger Loria, discussing not only these very grave findings, but also those of Jamal and Hansen in 1985, who reported that abnormal single-fiber electromyographs (muscle graphs)

were evident in 40 patients with postviral fatigue syndrome (PVFS, analogous to M.E.), 35 of whom had a Coxsackie infection, said: “These observations, as well as the recent interest in postviral fatigue syndrome (M.E.) may have considerable application.” [4]

The year in which he said this was 1988. We seem still to be waiting for someone to apply them.

The treatment of choice for those with post-polio is: “adequate rest, energy conservation, the pacing of activities, and reducing physical and emotional stress.” [5]

What on earth will happen in 30 years’ time to children now getting M.E. in a climate where they are disbelieved and told to push themselves through the pain barrier? The condition “post-M.E.,” which we may already be seeing in adults, could well await them with a vengeance.

The seriousness with which we take M.E. ought to parallel the seriousness with which we regarded polio. Byron Hyde and his team speak for us all:

“There is a myth among large numbers of physicians… that this is a short-term illness. We have reviewed the literature and can find no published study that supports the thesis that M.E./C.F.S is an illness of a short duration…

“Clinically, after the first year of illness, we have seen recoveries, but they have been the exception rather than the rule. We attempted to verify this and asked our 1,826 respondents to note the degree of their recovery over the period of their illness. Our survey group’s average length of illness was approximately seven years.

“The findings… demonstrate that, in this entire group, there has been only 2% recovery. The 2% total recovery of treated M.E./CFS patients suggests that the large number of pharmaceuticals, alternative medicines and various treatments used have been largely ineffective.” [1]

Dr. David Bell, a clinical instructor in pediatrics at Harvard Medical School, has noted that from, a group of 40 children with M.E., those with less severe symptoms, perhaps not surprisingly, were the most likely to have “recovered” three years later. Those children who were the most ill at onset “were in general ill three years later.” [6]

That was in 1989. It is not known whether symptoms will recur in the distant future. But two adults being studied by Dr. Bell’s team had been ill as teenagers, “recovered” after one year, but “subsequently developed the same symptoms up to 20 years later.”

As we shall see in further chapters [of M.E — The New Plague], the way in which we live our lives may well affect both the extent and the likelihood of a return of symptoms. But people who do not take a disease seriously or who do not know of its potential to cause later trouble are not being given the chance to take this step.

We now know that M.E., or atypical polio, is a serious and devistatingly debilitating, multi system malfunction leading to such profound weakness in some children that they are unable to speak and have to be tube-fed. There is accumulating evidence to suggest that it is a potentially a life-long condition.

However [unlike those with polio], these children can breathe; enteroviruses have an affinity for certain tissues and many do not attack the respiratory centra causing death.

In spite of the enormous body of evidence accumulating which links M.E. and polio, we are still seeing many M.E. patients disbelieved, exercised and treated as if it were only their own mental set which militated against recovery.

Is this simply because we cannot actually point to rows of coffins and iron lungs? REFERENCES

As the first step in prevention and management Os Polio survivors should undergo a complete general medical evaluation by a primary care s physician and a specialized neuromuscular evaluation by a knowledgeable and experts .enced polio specialist to establish a baselin from which to judge future changes and to develop an appropriate treatment plan. International Polio Network annually publishes a listing of self-identified post-polio clinics and polio knowledgeable health professionals.

Polio survivors should first and foremost take care of their health by seeking periodic, basic medical attention. Be nutrition-wise, avoid or reverse excessive weight gain; and stop smoking or overindulging in alcohol.

Polio survivors should listen to their bodies, Avoid activities that cause pain – pain is a warning signal. Avoid unrestrained use of päin. killers, especially narcotics. Do not oyeruse muscles but do continue activity thật does not worsen the symptoms. In particular, do not overexercise or continue to exercise through pain. Avoid activity that causes fatigue lasting more than 10 minutes.

Polio survivors experiencing symptoms should pace themselves in their daily activities, resting when tired. Stop for a 15- to 30-minute rest when needed, perhaps several times a day. Management may include the increased use. of assistive devices. A change of equipment or new bracing may be recommended

Polio survivors should educate themselves. International Polio Network through its con ferences and publications, Handbook on the. Late Effects of Poliomyelitis. for Physicians and Survivors, and Polio Network News, provides accurate and updated information. Polio survivors can benefit from the support and knowledge of other polio survivors. The Post-Polio Directory lists over 300 independent support groups worldwide.

International Polio Network publishes; a Handbook on the Late Effects Poliomyelitis for Physicians and Survivors covering the basic info about the late effects of po ($6.75 postpaid). O Polio Network News, a quarter newsletter keeping survivors an network informed about issues ed to polio and its late effects, re mended for all polio survivors (USA $16; Canada/Mexico Overs Surface $21; Overseas Air $25). A sample copy is available upon requ O Post-Polio Directory listing identified clinics, health profess and self-help groups, published March of each year. Questions are welcomed.

A sub-category of post-polio syndrome is post-polio progressive muscular atrophy and is defined as progressive new weaknes and atrophy in muscles with clinical or subclinical signs of chronic partial denervation/reinnervation compatible with previous acute polio. Polio survivors may experience one or more of the problems described above and should not become unnecessarily concerned about the label for their symptoms. Polio survivors may experience the same health difficulties as the general population some with symptoms mimicking post-polio syndrome, some magnified due to neurological damage from former acute polio.

The diagnosis is one of exclusion. A definitive test is not yet available. Some of the confusion and doubt among polio survivors, health professionals, and family members is due to the lack of common understand ing of terminology. It is helpful to think of post-polio problems in the following categories, remembering that the groupings are not distinct but parts of a continuum. The largest and most inclusive category is called late effects of polio or polio sequelae and defined as specific new health problems which result from polio caused chronic impairments, e.g., degenerative arthritis of overused joints, carpal tunnel syndrome and other repetitive motion problems, tendinitis, bursitis, failing joint fusions, overstressed joints due to compensatory body mechanics. Post-polio syndrome is a sub-category of the late effects of polio and is defined as the symptom cluster of new muscle weakness, fatigue, and pain resulting in a decline in functional ability and/or a new disability. Most clinicians use the following criteria to diagnose post-polio syndrome:

Confirmed history of acute paralytic polio. Many clinicians perform an electromyogram (EMG) to document changes compatible with prior polio.

Recovery followed by years of stability between onset of polio and onset of new problems which may include: gradual or abrupt onset of weakness in affected, and/or seemingly unaffected muscles, which may or may not be accompanied by excessive fatigue, muscle and/or joint pains, decreased endurance and function, and muscle atrophy.

Other conditions that might cause the problems listed above must be excluded.

The current consensus explaining post-polio symptoms focuses on the nerve cells and their corresponding muscle fibers. When the poliovirus destroyed or injured motor neurons, muscle fibers were orphaned and paralysis resulted: Polio . survivors who regained movement did so because nerve cells recovered to a certain extent. Further recovery is attributed to the ability of non-affected neighboring nerve cells to “sprout” and reconnect to the orphaned muscles. Survivors living for years with this restructured neuromuscular system are now experiencing the consequences — overworked surviving nerve cells and overworked muscles and joints, compounded by the effects of growing older. While the search for a viral cause continues, there is no conclusive evidence to support the concept that post-polio syndrome is a reinfection of the poliovirus.

Poliomyelitis (infantile paralysis) has been eradicated from nearly every country in the world since the development of the Salk (1955) and Sabin (1961). vaccines. In 1995, 6197 cases of polio were reported worldwide. The World Health Organization (WHO) estimates there are ten times as many cases of paralytic poliomyelitis as reports received, due to incomplete reporting especially in developing countries. WHO has targeted the year 2000 for the complete eradication of acute poliomyelitis.

Symptoms can include:

Unaccustomed fatigue – either rapid muscle tiring. or feeling of total body exhaustion. New weakness in muscles, both those originally affected and those seemingly unaffected. Pain in muscles and/or joints. Sleeping problems. Breathing difficulties. Swallowing problems. Decreased ability to tolerate cold temperatures.

The WHO estimates there are 12 million people worldwide with some degree of disability caused by poliomyelitis. A 1987 National Center for Health Statistics survey reported over one million survivors in the United States. About 640,000 of them reported paralysis resulting in some form of impairment. For years most of these polio survivors lived active lives, their memory of polio long forgotten, their health status stable.

Decline in ability to conduct customary daily activities such as walking, bathing, etc.

SRS

These general symptoms are experienced in varying degrees, and their progression can be insidious. They should not be dismissed simply as signs of ageing alone. Current research indicates that the length of time one has lived with the residuals of polio is as much of a risk factor as chronological age. It also appears that individuals who experienced the most severe original paralysis with the greatest functional recovery are having more problems now than others with less severe original involvement.

By the late ’70s, polio survivors were noting new problems of fatigue, pain, and additional weakness. By the mid ’80s, health professionals and policymakers recognized these new problems as being real and not “only in the patients minds.” Studies on this phenomenon called “post polio syndrome” have been and are still being – conducted in research institutions and medical centers.

Short Title: Bromocriptine and Post-Polio Fatigue

 

ABSTRACT

 

Objective: Determine the effectiveness of bromocriptine in the treatment of severe and disabling postpolio fatigue.

 

Design: Placebo-controlled drug trial in a pilot series of patients.

 

Setting: Outpatient rehabilitation hospital.

 

Patients: Of 83 patients without comorbidities who completed treatment with the Post-Polio Service, 5 of 8 patients who had paralytic polio and continued to report moderate to severe daily fatigue after complying with conservative treatments for post-polio fatigue agreed to be studied.

 

Intervention: Placebo was given for four weeks followed by increasing doses of bromocriptine mesylate (Parlodel®) administered at noon for 28 days reaching a total dose of 12.5 mg/day.

 

Main Outcome Measures: Daily logs of subjective fatigue and cognitive difficulties.

 

Results: Three of the subjects reported symptom improvement on bromocriptine but not on placebo. However, all subjects experienced nausea on bromocriptine, likely eliminating blinding. Drug responders had clinically impaired performance on neuropsychological tests of attention and information processing speed. Logged daily difficulty with attention, cognition, word finding memory, staying awake and fatigue on awakening were significantly negatively correlated with days on bromocriptine, but not with days on placebo, in drug responders.

 

Conclusions: A double-blind, placebo-controlled multicenter study will be needed to confirm bromocriptine’s effectiveness in treating attentionally-impaired polio survivors whose severe and disabling fatigue does not responded to conservative treatment.

BROMOCRIPTINE IN THE TREATMENT OF POST-POLIO FATIGUE: A pilot study with implications for the pathophysiology of fatigue.

 

Fatigue is the most commonly reported and most debilitating Post-Polio Sequelae (PPS) affecting the more than 1.63 million American polio survivors. [1] In national surveys of polio survivors, 91% reported new or increased fatigue, 41% reported fatigue significantly interfering with performing or completing their work and 25% reported fatigue interfering with self-care activities. [2,3] Importantly, polio survivors differentiate between physical tiredness that they associate with new muscle weakness or decreased endurance, and a “brain fatigue” that is characterized by fatigue plus difficulties with attention and cognition. Between 70% and 96% of polio survivors with fatigue reported concomitant problems with concentration, memory, attention, word-finding, maintaining wakefulness and thinking clearly, with 77% percent reporting moderate to severe problems with these functions. [3] On formal neuropsychological testing, only polio survivors reporting severe daily fatigue demonstrated clinically significant deficits of attention, concentration and information processing speed. [4] It has been hypothesized that both subjective fatigue and attention deficits in polio survivors result from poliovirus damaging neurons within the brain’s activating system. [3] Postmortem studies of 50 years ago demonstrated the consistent presence of poliovirus lesions in the midbrain reticular formation, posterior hypothalamus, thalamic nuclei, putamen and globus pallidus. [3,5] Recently, magnetic resonance imaging of the brain has shown small discrete or multiple punctate areas of hyperintense signal in the reticular formation, thalamic and caudate nuclei, putamen, centrum semiovale, deep and periventricular white matter only in polio survivors reporting fatigue. [3,6] Postmortem histopathology also found that neurons secreting neurotransmitters

 

known to activate the brain, especially dopaminergic neurons in the substantia nigra, were also damaged or destroyed by the poliovirus. [5,7] The reduced secretion of dopamine has been hypothesized to play a role in impairing polio survivors’ ability to activate the cortex, thereby generating difficulty with attention, concentration and maintaining wakefulness that polio survivors described as “brain fatigue.” [7] The hypothesized role of the basal ganglia and dopamine in activating the brain suggests that a dopamimetic agent would be the most promising candidate to pharmacologically treat brain fatigue. [7] However, any dopamimetic agent employed to treat fatigue should not stimulate (as do amphetamines and methylphenidate) nor require the functioning of (as do L-Dopa, monoamine reuptake blockers and monoamine oxydase inhibitors) the remaining poliovirus-damaged neurons in the brain’s activating system. Therefore, bromocriptine mesylate (Parlodel ®; Sandoz), a direct-acting, post-synaptic dopamine 2 (D2) receptor agonist, was chosen for a placebo-controlled study of a pharmacological treatment for post-polio fatigue.

 

METHODS

 

Subjects. Only patients who were without comorbidities that could cause fatigue or cognitive problems (e.g., psychiatric diagnoses, thyroid, cerebrovascular or cardiac disease, anemia, respiratory insufficiency, sleep apnea or hypopeneas, lupus or diabetes) and who successfully completed treatment for PPS were eligible for the drug trial. Of eighty-three patients who met these criteria, only ten continued to report at least moderate daily fatigue (the fatigue level required for inclusion in the study) after applying the conservative treatments of choice for post-polio fatigue, i.e., reducing physical and emotional stress, using appropriate assistive devices, energy conservation, adequate rest and the pacing of activities. [8,9,10] Of those ten, two met DSM-III-R criteria for a major depressive episode and were excluded. [11] Of the remaining eight patients, six agreed to the drug trial. One patient withdrew after her husband was severely injured in a fall, leaving five patients to be studied.

 

Procedure. Fatigue research is methodologically problematic since fatigue is subjective and therefore difficult to quantify. This problem is compounded by polio survivors’ difficulty acknowledging, let alone quantifying, their physical symptoms and the variability of their fatigue, both within and between days. [8] Therefore, all subjects gave written informed consent and completed a modified version of the PostPolio Fatigue Questionnaire (PFQ) for 14 days prior to beginning drug, rating subjective levels of fatigue five times during the day and rating daily and difficulty with motivation, attention, mind wandering, thinking clearly, concentration, word finding, object naming, memory, staying awake during the day, and muscle weakness on a six-point scale from “none” through “severe.” [3,4] All but one subject who was severely claustrophobic had magnetic resonance imaging (MRI) of the brain which were read by a radiologist blinded to the subjects symptoms (see 6). On another occasion, plasma ACTH was drawn at 11:00 AM after an overnight fast. (see 7) On the 15th day, blood was drawn at 10:00 AM for a complete blood count, chemistry, thyroid panel and plasma prolactin. Neuropsychological tests that assessed attention, concentration and information processing speed were then administered by a blinded examiner. The Double Letter Cancellation Test required subjects to cross-out two specified letters on a sheet filled with similar letters in the shortest possible time to assess selective and sustained attention. [12] The Gordon Diagnostic Systems continuous performance test, measuring focused and sustained attention, required subjects to watch numbers presented for 6 minutes on a 1 by 2 cm. LED display. [13] subjects were instructed to press a button only when the number “9” appeared immediately following the number “1” while two flanking LED displays also presented numbers including “9” and “1” (distractibility task) and while the flanking displays were dark (vigilance task). The Trail Making Test assessed visual scanning and visual motor speed by requiring subjects to draw a line to sequentially connect circles containing 25 ascending numbers (Part A) or sequentially but alternately connect circles containing ascending numbers and the letters of the alphabet (Part B) in the shortest possible time. [14] The Paced

 

Auditory Serial-Addition Test (PASAT) assessed complex attention and information processing speed by requiring subjects to sequentially add a series of 60 digits presented by a tape recording at three presentation speeds: one digit every 1.6, 2.0 and 2.4 seconds. [15] All neuropsychological tests were administered and scored according to accepted procedures.

 

Placebo/Drug Administration. The 14 days of pre-testing PFQs were reviewed with the subjects to determine that they understood how to rate and log their symptoms. Subjects were told that they would receive either placebo or a drug which it was hoped would reduce their fatigue symptoms. They were given 28 daily log forms and instructed to rate their fatigue upon awakening, at 12:00, 3:00, 6:00 and 9:00 PM. Subjects were instructed to describe any side effects experienced during the day and rate their overall difficulty with the subjective symptoms listed on the PFQ at 9:00 PM. Since bromocriptine almost invariably causes nausea, all subjects received placebo first. Subjects were given 10 numbered bottles, each containing three opaque capsules, and instructed to start with bottle number one and to take one capsule each day during the noon meal. Every three days, they would open the next higher-numbered bottle and take one capsule at noon. Subjects were unaware that they were receiving a cornstarch placebo during the first 28 study days. After 28 days on placebo, subjects were re-administered the neuropsychological tests, given another set of log forms, bottles with identical capsules and told to continue taking the capsules as they had been. Subjects began with 1.25 mg/day of bromocriptine and increased the dose by 1.25 mg every three days, reaching a total daily dose of 12.5 mg. After 28 days on bromocriptine, subjects were readministered the neuropsychologic tests and had blood drawn for bromocriptine plasma level and plasma prolactin, which is suppressed by the administration of dopamine receptor agonists.

 

Data Analysis. Since the small sample size prevented statistical comparisons, subjects’ individual measurements and group means were compared to established clinical norms to determine whether the physiological variables or neuropsychologic test performance were clinically abnormal. (Table 1) SYSTAT (Version 6.0) was used to calculate product-moment correlations and linear regressions for daily fatigue and symptom difficulty ratings with days on placebo and bromocriptine for each individual subject. [16] Correlations were transformed to z scores, averaged across subjects, and then transformed back to correlations. [17] (Table 2) Because the large number of variables being correlated increased the probability of obtaining significant correlations by chance, the Bonferroni inequality was applied to decrease the probability (p) value needed for significance by dividing the p value by the number of variables being correlated. The regression equations were used to calculate the fatigue and symptom difficulty rating for each drug responder for the last day on placebo (day 28) and on bromocriptine (day 56). The mean calculated fatigue and symptom difficulty ratings are shown in Figure 2.

 

RESULTS

 

Demographics. Subjects (3 female; 2 male) were 49 ( ± 2.1) years old having had paralytic polio at age 5 ( ± 2.6) in 1949 ( ± 2.4) and 15 ( ± 3.0) years of education. One subject had been a diplegic wheelchair user since polio. The others had ambulated for 35 years without assistance before the onset of new muscle weakness; 3 were prescribed a straight cane and one a molded ankle/foot orthosis when treated for their PPS. Subjects rated their current daily fatigue as moderate to severe. Four subjects were retired on Social Security disability as a result of fatigue preventing continued employment; the remaining subject worked part-time as a secretary.

 

Drug Response: Neuropsychological Testing. Three subjects reported a noticeable reduction in fatigue and related cognitive symptoms on bromocriptine as compared to placebo. Drug responders reported that they “felt awake” and “had a clear head” for the first time in several years. Two subjects reported no effect at

 

all on bromocriptine or placebo. There were clinically significant differences in baseline measures between drug responders and non-responders (Table 1). There were more than twice as many areas of hyperintense signal on MRI of the brain on average in the drug responders. Fasting ACTH was abnormal in all of the drug responders in that it was not elevated above the baseline value expected for non-fasting subjects at 11:00 AM. [7] A clinically significant increase in mean ACTH was seen in the non-responders, one of whom had a normal elevation in fasting ACTH. The baseline mean plasma prolactin level was nearly doubled in the drug responders, suggesting reduced brain dopamine activity. In the drug responders, the lower mean number of correct responses at baseline on the Gordon distractibility and vigilance tests and on the 2.4 numbers/second presentation of the PASAT were clinically abnormal, as was the longer time required to perform the Trail Making Test (Part A). Scores on all neuropsychological measures in all subjects moved toward or reached normality with repeated testing on placebo and then on bromocriptine. Prolactin decreased from 11.2 ( ± 6.2) ng/ml at baseline to 3.2 ( ± 4.0) ng/ml on bromocriptine as would be expected with a dopamine receptor agonist. The plasma level of bromocriptine was below the detectable range in all subjects.

 

Drug Response: Symptom Logs. In the drug responders, the rating of fatigue upon awakening and difficulty with attention, word finding, mind wandering, concentration, remote memory, thinking clearly decreased and were significantly negatively correlated with days on bromocriptine, but not with days on placebo (Figure 2; Table 1). These ratings decreased by about one grade, from above “mild to moderate” to “mild” (Figure 2). Fatigue decreased from about “moderate” to “mild to moderate,” with fatigue upon awakening decreasing most (55%). Subjective muscle weakness did not change on bromocriptine or on placebo. In the drug non-responders, difficulty with word finding, memory, and object naming were significantly positively correlated with days on bromocriptine. However, fatigue at noon and 9:00 PM and muscle weakness were significantly positively correlated with days on placebo. Nevertheless, the nonresponders did not complain of an increase in any of these symptoms during either phase of the study.

 

Side Effects. The most common complaint was a low-grade nausea that is the most frequently reported side-effect of bromocriptine. All subjects reported nausea for from 2 to 10 days (a mean of 28% days) on bromocriptine. Two subjects reported nasal fullness, one for 9 days and another for 2 days, for a mean of 20% of the days on bromocriptine. The latter subject also reported a daily dull headache on bromocriptine that may have been related to nasal fullness. However, no subject discontinued bromocriptine because of these side effects. At the highest dose of bromocriptine, one subject did have an episode of severe nausea, followed by six brief episodes of syncope with high-grade atrioventricular block when she attempted to vomit. While this subject had only two previous episodes of mild nausea on bromocriptine, she did have a life-long history of syncope during vomiting. Although cardiodepressor syncope was not a previously known side effect of bromocriptine, the drug was discontinued.

 

DISCUSSION

 

This pilot study of severely fatigued polio survivors suggests that bromocriptine may be of use in the treatment of post-polio fatigue that has not responded to conservative therapies. However, the small sample size and methodological limitations make this suggestion merely tentative. Since nausea was universally experienced, all subjects may have realized that they were receiving active drug and were thereby biased toward reporting reductions in symptoms. The percentage of days on which side effects were experienced on bromocriptine was higher in the responders (48%) than non-responders (34%). Although the placebo phase was not compromised, the bromocriptine phase of the study may have been as unblinded as an open-label drug trial. Reductions in morning fatigue and fatigue-related cognitive symptoms as the dose of bromocriptine increased were not paralleled by drug-related improvements in neuropsychologic test scores, most likely since the same form of the tests was administered on placebo

 

and on bromocriptine. Subjects repeatedly taking the same test would be expected to demonstrate a learning effect and have their test scores improve. This has been seen even in polio survivors with severe fatigue who were repeatedly administered the same neuropsychologic tests over the course of several hours [4] It was also surprising that drug responders noticed no reduction in fatigue during the afternoon, since bromocriptine was administered at noon so that a peak blood level would be reached at 3:00 PM when many polio survivors report hitting an afternoon “wall” of fatigue. Since the pharmacokinetics of bromocriptine could differ from the time course of its pharmacological effect, as is seen with D2 receptor antagonists, moving the dose of drug to before sleep or upon awakening may prolong any beneficial effect of the drug into the afternoon. [18]

 

A Central or Peripheral Pathophysiology of Fatigue? Several other agents have been studied in an attempt to treat post-polio fatigue. In placebo-controlled studies, high-dose prednisone and amantadine, a drug with anticholinergic and dopamimetic properties, did not decrease fatigue. [19,20] An open-label trial of pyridostigmine was conducted in 25 polio survivors whose fatigue had not responded to conservative treatments. [21] After at least one month on drug, 64% of subjects reported a 56% decrease in “general fatigue,” a finding comparable to the 55% decrease in morning fatigue in 60% of the subjects in this study. The authors concluded that although the subjective complaint of fatigue has multiple causes, it was reduced in their subjects by pyridostigmine enhancing conduction at the neuromuscular junction and thereby increasing muscle strength and decreasing muscle fatiguability. Since bromocriptine reduced morning fatigue and fatigue-related cognitive symptoms, but had no effect on subjective muscle weakness, it is likely acting centrally to stimulate dopaminergic receptors within the brain’s activating system. This conclusion is supported by a placebo-controlled study of healthy subjects who were administered remoxipride, a potent and selective D2 receptor antagonist. [18] The most frequently reported effects of D2 receptor blockade were “moderate fatigue,” “mild somnolence” and “difficulty concentrating.” Statistically significant, dose-related increases in subjective “drowsiness” and impairment on neuropsychological tests of auditory vigilance, continuous attention and critical flicker fusion wer also found following D2 receptor blockade. However, decreased neuromuscular junction transmission impairing muscle contraction and decreased attention resulting from impaired brain activation are not mutually exclusive causes of post-polio fatigue. The contribution of both muscle weakness and impaired attention to the complaint of fatigue was documented by administering the Post-Polio Fatigue Questionnaire as part of the 1990 National Post-Polio Survey. [3] Multiple regression revealed that the only significant contributors to the prediction of daily fatigue severity were “difficulty focusing attention” (r=0.31; p=.005) and “muscle weakness” (r=0.19; p=.023). Actually, there may be an interaction between impaired transmission at the neuromuscular junction, decreased brain activation and symptoms of fatigue. As early as 1939, muscle spindle afferent activity was recognized as important in the maintenance of “alertness.” [22] Neuromuscular transmission blockade, which eliminated muscle activation and thereby afferent muscle spindle discharges, was shown to inhibit the ascending reticular activating system, decrease cortical activation, cause “drowsiness” and even induce a level of anesthesia sufficient for surgery. [23,24,25] Further, the relaxation and reduced recruitment of motor units have been identified as peripheral signs of central fatigue, possibly resulting from a decrease in the activity of the descending reticular activating system. [26,27]

 

Clinical Application and Caveats. These very preliminary findings suggest that bromocriptine may be helpful in treating polio survivors whose fatigue is more central in origin (i.e., associated with impaired attention and cognition) while pyridostigmine may be helpful in treating patients whose fatigue is more peripheral (i.e., associated with muscle weakness, fatiguability or decreased physical endurance). Responders to pyridostigmine had higher fatigue ratings at baseline, while drug responders in this study had clinically significant impairments of attention and information processing speed, more hyperintensities on MRI, an absent ACTH response to stress and increased plasma prolactin. Taken

 

together, these data suggest that any medication for post-polio fatigue will benefit only the most fatigued, neuropsychologically impaired or neurophysiologically abnormal patients who have not responded to conservative therapies. This conclusion is underscored by the experience with the drug non-responders. One was the least impaired of the subjects, reporting moderate to severe daily fatigue, having two hyperintensities on MRI, scores on only two of the attention tests that fell just below the normal range, and being the only subject able to work, albeit part-time. The other non-responder reported severe daily fatigue, had one punctate hyperintensity in her rostral reticular formation on MRI, but had no abnormalities on neuropsychological testing. However, her daily logs revealed that she was applying none of the conservative treatments that had been recommended. She neither paced her activities nor rested during the day. She went to sleep after midnight on 87% of the study days, compared to a mean of 26% of study days for the other subjects. Following the study, she modified her schedule and her daily fatigue decreased from severe to moderate to severe without the use of medication. This subject’s inability to implement the lifestyle changes necessary to treat her fatigue may be responsible for the positive correlations between days on placebo, fatigue, cognitive symptoms and muscle weakness in the nonresponders. Polio survivors’ frequent non-compliance with fatigue-reducing lifestyle changes is well described. [8,28] However, medication is not a substitute for self-care and no medication to treat postpolio fatigue should be prescribed until all conservative therapies have been consistently applied by the patient and found inadequate to reduce fatigue sufficiently to allow a satisfactory level of personal, vocational and recreational functioning.

 

Future Research. The finding that only 10% of compliant patients without comorbidities reported moderate or greater daily fatigue after treatment by the Post-Polio Service is hopeful, indicating that conservative therapies appear to be successful in treating most polio survivors’ fatigue. However, the success of non-pharmacological therapies makes difficult identifying a sufficiently large sample of appropriate subjects at any one facility. Clinician/researchers thoroughly familiar with treating polio survivors and PPS at a number of post-polio clinics will be needed if a sufficiently large sample is to be recruited for a double-blind, placebo-controlled, cross-over study of the efficacy of bromocriptine in the treatment of severe, treatment-resistant post-polio fatigue. Since nausea was reported by all subjects, domperidone – a dopamine receptor antagonist that does not cross the blood-brain barrier and has been shown to counteract the nausea caused by dopamimetics in Parkinson’s patients without decreasing bromocriptine’s efficacy – could be given with bromocriptine to allow a blinded, cross-over design. [29] However, the safety of bromocriptine remains a concern. Given the association of nausea and syncope in one subject, dopamimetics may be contraindicated in polio survivors with a history of syncope or even in those with bulbar polio that damaged brain stem cardioregulatory centers. [30,31,32] Also, the long-term effects of dopamimetic agents in polio survivors have not been studied. Receptor down-regulation and the development of tolerance with the chronic use of a D2 receptor agonist is a possibility. Down-regulation occurs with negative clinical consequences following chronic use of dopamimetics in Parkinson’s disease patients. [33,34,35] Bromocriptine-induced receptor down-regulation could actually increase fatigue by combining with reductions in D2 receptor number and the level and activity of dopamine-synthetic enzymes in the nigra and putamen that accompany aging. [36,37] These reductions, thought to occur “due to impairment of cellular regulatory systems or to decreased presynaptic dopamine input” resulting from attrition of dopaminergic neurons, may be accelerated in polio survivors and have been implicated in the pathogenesis of fatigue as polio survivors reach midlife. [3,7,27] On the other hand, it has also been suggested that dopamine receptor agonists may exert a “protective action” on poliovirus-damaged, metabolically impaired dopaminergic neurons since they reduce the demand for pre-synaptic dopamine production. [3,38] Reduced dopamine production would decrease neurons’ internal metabolic requirements and lower oxidative stress by limiting the amount of hydrogen peroxide formed by the action of MAO-B. [38] Thus, administration of bromocriptine may not only potentially decrease symptoms of brain fatigue but also could possibly slow the metabolic failure of the remaining poliovirus-damaged

 

dopaminergic neurons. [39] Future studies will need to address these concerns as well as objectively document fatigue’s peripheral and central symptoms and signs if the pathophysiology of fatigue, location of drug action, and drug efficacy and safety are to be determined.

Respirators Ventilators Oral Positive Pressure

Oral Positive Pressure

Augusta Alba

All forms of airway ventilators are positive pressure ventilators or pressure ventilators. We consider the mouth one of the best forms of using a positive pressure simply because you can use glossopharyngeal breathing concomitantly with mouth positive pressure breathing. The airway breathing can give you a tidal volume as large as the volume you can receive in a body ventilator; iron lung, and poncho. No other body ventilator; and that includes the Pneumobelt, the chest respirator, and the rocking bed, can give you the same large amount of volume. The older the ventilator-dependent individual becomes, the more he requires a ventilator that can give him a larger volume.

Basically mouthpieces of many shapes and forms can be used. The one that is most convenient both for sitting and lying down has some degree of angulation. For years at Goldwater, and now throughout the country we have been using a Bennett Lipseal with a straight mouthpiece, either with a simple plastic strap with a hook that attaches behind your mastoid or canvas straps above and below the ears with Velcro closure. This allows you to use the mouth positive pressure when you are lying down and when you fall asleep. It is a conditioned reflex.

Acute toxic metabolic states can occur with certain disease conditions, or infections can be contracted in which you have a decreased state of consciousness. In these circumstances you should be tracheostomized, at least temporarily, if not permanently. One young man went through a period of renal failure and needed to be tracheostomized because he was in a state of delirium. Now, months later, he has peritoneal dialysis on a regular basis and has decided to take his tracheostomy tube out. He’s back to frog breathing, although he no longer can do it for prolonged periods of time.

About 12 years ago we did a study at Goldwater that showed there are people who cannot breathe longer than 5 minutes at a time with frog breathing. This occurs in intrinsic lung disease and possibly in severe kyphoscoliosis or in repeated bouts of pneumonia or other complications. If you don’t have normal lungs, no matter how hard you try, it may not be possible because your blood oxygen level drops too rapidly for you to use this as your only method of breathing. When the saturation drops to 85%, you will want to use some form of breathing other than frog breathing by itself.

If an individual has repeated difficulties in handling secretions, we may recommend tracheostomy. Sometimes an individual doesn’t have caretakers available to perform the postural drainage and chest physical therapy needed. If there have been recurrent bouts of atelectasis or of acute pneumonia with a prolonged period of incubation and secretions that will be present for several weeks, we may decide to tracheostomize. Aspiration also occurs when you may change from mouth positive pressure to tracheostomy positive pressure.

Dr. Adolph Rataka is working on a form-fitting mask, which he hopes to develop commercially. He is also working on a form-fitting mouthpiece.

Nasal CPAP (positive pressure ventilation) has now been given successfully with a nasal mask, instead of mouth positive pressure ventilation, not only during the day but possibly in your sleep. Just as you learn to close your softpalate when you are breathing through your mouth, you can learn to close your mouth when you are breathing through your nose with positive pressure in sleep. occasionally there is a problem with loosening of the lower incisors from the use of the mouth positive pressure mouthpiece. This may require extraction and the fitting of a permanent partial plate.

 

Plastic Wrap

Ernest W. Johnson

The types of polio that are going to require ventilation we used to divide into abortive, nonparalytic, and paralytic. Abortive meant only the gastrointestinal phase of the disease was present. it never entered the central nervous system. Most of us had this type of polio, with no residual effects. The non-paralytic type does not involve functional weakness. If the disease invades the central nervous system, technically it is paralytic, even if there is no functional weakness. If more sophisticated tests were used, we could perhaps see some weakness. The paralytic variety is further divided into bulbar and spinal types. Bulbar polio has to do with muscles of the pharynx. It is often mistakenly thought that people on ventilators have bulbar polio, but they do not. They have high spinal polio. Spinal polio is divided into the high spinal type, in which ventilators are almost always necessary, and the low spinal type which involved the lower extremities.

The breathing muscle, the diaphragm, is responsible for about 55% of our vital capacity. If we lose control over the diaphragm, as in the high spinal type of polio, we might need ventilation during the acute phase, however, if we have control over our intercostal muscles, our chest muscles, and what we call your accessory neck muscles, we can still probably breathe alter the acute phase is over, because we still have 40% ventilation.

How do we breathe? Basically we develop a negative pressure within the lungs so that the atmospheric pressure will force air into the lung. If the atmospheric pressure is 760 mm Hg or cmH20, and we lower our diaphragm and raise our ribs so that The space in our chest lowers the pressure about 3 or 4 cm, air comes in. That is the principle of the plastic wrap ventilator or the iron lung. It deals with the ambient pressure, the pressure around the body. This pressure is reduced by either putting the person in an iron lung or putting the person in this plastic wrap.

The wrap (Dr. Alba calls it a poncho) is hooked up to a pump so that the pressure around the body will be considerably less. If it is at 20 cm H20 negative pressure around the body the pressure in the air passages would be -3 or -4, so air would come in the mouth. The so-called negative pressure ventilators, like the plastic wrap, are no different from positive pressure by mouth as Dr. Alba was describing. Pressure higher than atmospheric can be applied at the mouth to force air in, or pressure can be withdrawn from around the body so that atmospheric pressure is then positive. The physiological effects are the same.

With respect to the efficiency of the various ventilators, this has been well documented over the years. The iron lung or the tank respirator is considered 100% efficient. The next most efficient is probably the plastic wrap, which is close to 100% and is for people who are using positive pressure during the day I don’t think there is any reason for using an iron lung any more, except if you don’t have the Thompson AC-driven pump. The advantage to the plastic wrap, of course, is that it doesn’t have anything in contact with the skin. It would be nice to use in spinal cord injury, and we do use it because people with spinal cord injury don’t have surface sensation. Next is a chest abdomen cuirass. It is about 60% as efficient as the iron lung, if it is fitted properly. At about 50% efficiency is the Pneumobelt. The unfortunate aspect of the Pneumobelt is that you have to be almost sitting at about 45 degrees for it to work because it works by pushing the diaphragm up and then using active expiration and passive inspiration. It is a different principle, but it works very nicely sitting in a chair

Finally, the least efficient are the rocking bed and the chest respirator. The chest shell just covers the chest, and we rarely use them any more. Most of the cuirass types are chest-abdomen respirators, that is they cover the abdomen too. We nave the Monaghan and the turtle types. The plastic wrap respirator has the advantage of not causing any irritation around the skin. The new plastic wrap has a zipper so it is convenient and easy to put on. This type is very close to natural breathing. I would recommend the use of positive pressure by mouth during the day and the plastic wrap at night I feel there has been a general reluctance to indict the tracheostomy by our group, but I will indict it because I think it’s very often an unnecessary operation. It is often done because the person arrives at the emergency room and no one knows what to do. I think our technology today is such that we ought not to have so many tracheotomies. If you have one, I think you can practice closing it with the Plum button. Fred Plum was one of the original respiratory center directors, a neurologist, and became interested in this. He devised this button so that you could close off a tracheostomy without compromising the lumen of the trachea.

 

Respiratory Equipment

Eric Killam

Thompson Respiration Products and J. H. Emerson & Co., the manufacturers of the original iron lung, are manufacturing wraps in two different styles: the poncho wrap, which is a half wrap, and a full body wrap. LIFECARE is also manufacturing a full body wrap. The wraps now are gaining wide respectability across the country There has recently been a. lot of publicity about the effectiveness of wraps and a lot of different application sensors. I think this shows a trend toward the rehabilitative issue of independent living. I think this is a very positive issue. Chest shells are still being manufactured by two or three companies. LIFECARE is manufacturing chest shells and cuirasses. Thompson is manufacturing chest shells and there are also independent companies around the United States who are doing custom shell work, using body casts that are made in the home or in orthopedic-type jobs. The negative pressure ventilators that are used to power wraps and shells can be obtained from Emerson and the chest respirator from Thompson. The Thompson negative pressure ventilator offers both negative and positive pressures. There are various alarms for patient safety and also proximal airway sensing potential. Both of the negative pressure ventilators just mentioned are very reliable pieces of equipment, and they have both been designed for home application

Iron lungs and rocking beds are still being manufactured by Emerson. They manufacture these on a limited supply and through order only. Many of you have seen Sunny Weingarten’s quarter lung. This is a recent development and is a very positive step as far as portable iron lung equipment. Positive volume ventilators are being manufactured by numerous companies. Life Products is manufacturing the LP3 and LP4, which are both portable and very reliable units. Thompson produces the M25 and the M3000 XA. Both of these units offer variable I:E ratios and assist capabilities. The M3000 XA also features a sigh mode. LIFE-CARE currently manufactures the PVV and will soon be releasing a PLV-100. The PLV-100 is designed for home use, as is the PVV and will feature IMV capabilities, variable I:E ratios, and proximal airway pressure sensing and assist. All of the equipment I have mentioned is good, up-to-date equipment. Many patients who are using ventilators at home are doing just fine on equipment manufactured during the polio era, but manufacturers feel pressure to develop equipment to suit the needs of various types of individuals. Cost and effectiveness are important considerations. Emerson is located in Boston, Massachusetts. Sunny Weingarten, Life Products, Thompson, and LIFECARE are all in the Denver area. Sunny has a data sheet on his Porta Lung, Thompson has data sheets on their equipment, and LIFECARE would be glad to send data sheets on all of our equipment.

Dr Henry writes about Running

Dr. Henry writes about running

Many of you probably recall seeing the award winning film, “Chariots of Fire” which was a somewhat historical story about two English track stars of the 1924 Olympic games. One was a Jew and one was a Christian. Each eventually won a gold medal, and had something to prove of a personal nature. A personal crisis for the Christian occurred when he learned that he would be required to run a preliminary heat on a Sunday which would have violated his religious principles. He refused to run in his best event but latter won a different event in which he was not the favorite. On the Sunday in which he would have raced, the film depicts him delivering a sermon while his teammates are running their respective races, and he quotes from the Bible from the prophet Isaiah, chapter 40. Some of the lines delivered from the old King James Bible are: “Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding. He giveth power to the faint, and to them that have no might he increaseth strength. Even the youths shall faint and be weary, and the young men shall utterly fall; But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.”(verses 28-31)

Regardless of your religious beliefs, I believe these words are particularly inspiring and encouraging to many polios. For myself and thousands of others prior to Salk and Sabin, the polio virus stopped us from running. I last ran on September 10, 1950. I have many wonderful B.P.( before polio) memories of running. I remember winning a fifth grade sprint on the school yard of J.E.B. Stuart School. I can remember racing friends around the 3100 block of North and Garland Avenues in the northside of Richmond. In the summer of 1950, I vividly recall running the bases after hitting long balls in camp baseball games. Less vivid are the simple runs up a flight of steps at home or school, climbing a neighbor’s fence to retrieve a ball, or catching a football on the run. I am sure many of you have wonderful memories of your B.P. days, particularly if polio made a significant difference. These are positive and healthy memories which sometimes seem only like fantasies. But at a particularly time, these memories really happened, and they are precious to me and to you. In our lives A.P.(after polio) most of us were able to overcome obstacles, adapt to our real limitations, complained little, adjusted to our unique situation and achieved goals. In a sense, we did “walk and not faint”.

With Post Polio Syndrome, we are faced with some of the same struggles as a half a century ago. We have grown faint and weary, and we are not youths. Our nerve and muscle cells are much older and overworked. We have a somewhat different challange, but this time we have mature minds, immeasurable experience, and most valuable, we have each other as well as those who have known our struggles and loved us for who we are. The shared experince in our group meetings and what we try to communicate in this newsletter is meaningful to many. I believe that most of us are individual warriors and have not easily talked about our polio pasts, but with PPS, we have an opportunity to talk, share, learn ,and support each other. The shared experince helps us, at least in our souls to “mount up with wings as eagles…and run and not be weary…to walk and not faint.”

With this spirit, we can run a good race. Another religious leader in the Bible (Paul) once said “I have done my best in the race, I have run the full distance, and I have kept the faith. And now there is waiting for me the prize of victory awarded for a righteous life…..(2 Timothy 4:7-8)

While training in Washington, D.C., Dr. Silver worked with Dr. Lauro Halstead who is one of the nation’s leading authorities on the diagnosis and management of polio-related health problems. Dr. Silver approaches the late effects of polio from both a professional and personal level. Her mother, her mother’s father and mother’s brother had polio. Dr. Silver also wrote THE BUSINESS OF MEDICINE, book for acquainting physicians and medical students with the many business aspects of medicine and is now on the faculty of Harvard Medical School/Spaulding Rehabilitation Hospital

For polio survivors it came as something of a shock – these new symptoms of weakness, fatigue, pain and difficulty with breathing and swallowing. How could it be that after all these years, polio could come back to haunt them again?

Indeed, the late effects of polio, or Post-Polio Syndrome as it is often called, can be more devastating than the original disease. The most likely explanation for the new symptoms is that muscles which were weakened by the original polio virus have had to work excessively hard for many years. This has lead to overuse of these muscles and a faster than normal aging process. For many people, this seems “all of a sudden.” In reality, it is a process that takes many years before any new symptoms are noticeable.

In fact, the diagnosis of Post-Polio syndrome requires at least four things:

  • 1) A History of paralytic poliomyelitis
  • 2) At least some neurological recovery from the paralysis
  • 3) A stable period for many years, and, . 4) new symptoms which can be traced to the original polio.

As we become more knowledgeable about the mechanisms which cause the symptoms, we are able to offer more appropriate treatment options for polio survivors. Our understanding of Post-Polio Syndrome is rapidly evolving and currently there are treatment options which were not available even as recently as one year ago. Scientists and clinicians are hard at work with some exciting prospects for the future as well.

Therapeutic exercise

Initial studies done to evaluate the effect of exercise on people with new weakness from their old polio gave conflicting results. Some people got stronger and others got weaker with prescribed exercise protocols. Recent studies, however, suggest that most people with the late effects of polio do benefit from non-fatiguing exercise programs.

The first step in prescribing any exercise program for someone who had polio is to determine which extremities are involved. This is important because someone who only has their legs involved can do very vigorous exercises with their arms, while limiting their legs to non-fatiguing exercises. In contrast, if someone has both their arms and legs affected, then all exercises must be non-fatiguing. Determining which extremities have evidence of old polio is done with electrodiagnostic studies (EMG and never conduction studies) which are ordered by a doctor. These studies are important in guiding he therapeutic exercise prescription.

In most cases, an appropriate exercise program will help strengthen muscles as well as improve heart condition, ON the other hand, a program which is too strenuous can accelerate muscle weakness, and a program which is too easy may not help at all.

Therefore, it is important to exercise under the guidance of a health care professional who is knowledgeable about the late effects of polio.

Medications

While there are too many medications to adequately describe in this article which are used to treat post-polio symptoms, there is one exciting drug which recently had very favorable results during a trial at the Sister Kenny Institute in Minnesota. This drug is called pydirdostigmine or Mestinon. Pyridostigmine was shown to significantly improve strength, endurance and reduce fatigue in-patients who were studied. In addition, side effects noted in the study were minimal. While not appropriate for everyone, pyridostigmine is currently gaining favor among doctors who treat Post-Polio Syndrome.

Assistive devices and braces

There are many new styles of braces which can be used to stabilize weak legs. Braces should be used to stabilize weak legs. Braces should be made of lightweight materials and should be updated regularly Old, heavy braces which don’t fit well can make post-polio symptoms worse.

Appropriate assistive devices (e.g., crutches, canes, etc.) should be prescribed by a health care professional who is skilled in treating patients with Post-Polio Syndrome. For example, many people who have new leg symptoms may start using a cane to walk. This puts a new stress on the arm which is holding the cane. If the arm also has evidence of old polio on electrodiagnostic studies, this can promote symptoms of weakness, fatigue and even pain in the arm. Even if the arm is not involved, an assistive device which is used improperly can cause other injuries like tendinitis, never compression, etc.

Appropriate braces and assistive devices certainly can make walking easier and can help to prevent unnecessary falls; however, they may cause further weakness or other complications and should be prescribed with this in mind.

Prevention of falls

Because weakness and balance are so intimately linked, any new weakness can cause falls. Unfortunately, bones surrounding weakened muscles are tin or osteopenic, and therefore more likely to fracture when a fall occurs. A fall which results in a fracture can be a devastating setback for someone who has had paralytic polio. People who have had polio are often maximally using their muscles to move about and any disruption, such as a fracture, which may take weeks or months to heal, can be devastating. Therefore, preventing falls if of great importance to a person who has had polio.

A prime time for falls is during poor weather conditions. Thus, an attempt should be made to limit time spent outdoors during bad weather. Appropriate assistive devices (e.g., canes, crutches, etc.) and braces should be used to increase safety — especially during the winter when weather conditions can be precarious. Slippery bathrooms are also the site of many unnecessary falls. Simple modifications such as a tub bench or shower seat, grab rails and a non-slip mat can greatly reduce the risk of falling in the bathroom.

Keeping a record of how often, where and why falls are occurring can help our doctor troubleshoot for you. It is extremely important to prevent as many falls as possible. When patients ask me how many times is too many, I reply that I want to do everything possible to eliminate all falls.

Respiratory treatment options

Because breathing is something we do continuously, it is very difficult to rest the respiratory muscles. People who are experiencing late respiratory complications due to polio are sometimes candidates for CPAP or Continuous Positive Airway Pressure. What may even be more comfortable and effective is BiPAP or Bi-level Positive Airway Pressure. There are several commercially available masks which can be tried for maximal comfort.

Some respiratory conditions are reversible, so any symptoms should be carefully reviewed with your doctor in order to make the correct diagnosis.

In the future

Each year brings new treatment options, and it is important for people who have had paralytic poliomyelitis to be ware of these exciting new advances. The future is certain to bring more options, and although we all wait impatiently, we can anticipate them with renewed hope.

Pyridostigmine

Pyridostigmine (Mestinon) was recently given to patients with Post-Polio Syndrome in a double-blind crossover study at the Sister Kenny Institute in Minnesota. Dr. Barbara Seizert and colleagues reported that patients in the study had significant improvement in strength, endurance and reduction of fatigue. In addition, there were minimal side effects. Pyridostigmine has also been used to treat other disorders such as Myashenia Gravis and Parkinson’s. Pyridostigmine must be prescribed by a doctor and although

the dose can vary, a typical maintenance dose is 60 milligrams, three times a day.
