ABSTRACT

Introduction/Aims: Surviving motor units in neurogenic diseases demonstrate collateral reinnervation. Scanning electromyography (EMG) reveals normal motor unit corridor length, but with “silent regions,” suggesting that reinnervation does not result in increased motor unit size but may increase motor unit complexity. Motor unit magnetic resonance imaging (MUMRI) pairs MR imaging with electrical nerve stimulation to visualize individual motor units. This study aimed to assess the motor unit dimensions and complexity in patients with previous poliomyelitis compared to healthy controls.

Methods: Patients with a history of polio were recruited from the British Polio Fellowship, compared to a retrospective cohort of healthy controls. They underwent medical history and examination of lower limb power, fatigue assessment (fatigue severity score, FSS), and a 3 T MUMRI scan of the less-affected lower limb. The cross-sectional area, maximum, and minimum Feret diameter of the motor unit territories in tibialis anterior were calculated. Motor unit complexity was computed using the Hausdorff box-counting method.

Results: Of 12 polio survivors, n = 8 (6 female) were suitable for analysis and were compared to 19 controls. The mean motor unit maximum Feret diameter was 10.3 ± 3.1 mm compared to 8.4 ± 5.2 mm in controls (p = 0.34). The mean shape complexity was 0.59 ± 0.12 compared to 0.45 ± 0.2 in controls (p = 0.03).

Discussion: Polio survivors demonstrate motor units with normal dimensions but increased shape complexity, indicating nonuniform collateral reinnervation largely limited to existing territories. The size and shape of motor units could help in understanding the physiological processes behind reinnervation, both in polio and other neurogenic diseases such as amyotrophic lateral sclerosis.

1 | Introduction

Understanding the neurogenic remodeling process is key to understanding the changes seen in altered motor unit potential (MUP) morphology in neurogenic diseases that form the basis of clinical electromyography (EMG) interpretation. However,

it remains unclear whether reinnervation increases the spatial territory of a motor unit, or if it occurs exclusively within the original boundary.

While concentric EMG shows neurogenic MUPs are characterized by increased amplitude and duration, this is largely a

product of the closest ~10 fibers [1] and reflects increased fiber density in the 1 mm around the needle [1] rather than the whole 10–20 mm motor unit territory [2–4].

While macro-MUP amplitude increases in neurogenic diseases [5–8] indicating an increased total fiber count for the whole motor unit, and single-fiber EMG confirms increased fiber density in polio survivors and other neurogenic conditions [9, 10], these methods do not measure spatial extent.

Attempts to measure territory directly have been contradictory. Scanning EMG has shown only minimal increases in motor unit dimensions in polio [11] or other neurogenic disorders [4], but with “silent regions” suggesting an increased complexity of the motor unit structure [12] whereas multielectrode EMG has shown significant increases in territory [13]. This variability may be explained in part by the random path of the electrode, which will tend to underestimate motor unit dimensions, especially those with complex profiles [14].

Animal studies using the glycogen depletion technique [15] have shown either a decrease in territory [15–17], a modest increase [18], or inconsistent results [19]. It therefore remains unclear whether the characteristic changes seen in neurogenic disease reflect an expanded motor unit territory or are solely due to increased fiber density.

We recently developed a magnetic resonance imaging (MRI)- based technique (motor unit MRI or MUMRI) capable of imaging the size and shape of human motor units in vivo [20]. MUMRI uses a pulsed gradient spin echo (PGSE) sequence, which is inherently sensitive to the movement of water molecules. When combined with in-scanner electrical nerve stimulation, the contraction of the muscle fibers in a given motor unit results in a localized signal void in the MR image. This in turn allows the quantification of the motor unit dimensions, crosssectional area, and shape [21]. The technique has been used to image single motor units in healthy controls [2], as well as to track the motor units through multiple axial slices of the lower leg, producing a 3D image of the motor unit [22].

In this study, we compared the motor unit dimensions of polio survivors who exhibit significant loss of motor units [23–26], extensive motor unit re-modeling [10] and very high amplitude MUPs [27], against a cohort of previously studied healthy controls. Our primary research question was whether or not compensatory reinnervation is limited to or extends beyond the normal territory of a human motor unit.

2 | Methods

Ethical approval was obtained from the Newcastle University Faculty of Medical Sciences Ethics Committee (2603/34701). Participants were recruited via the British Polio Fellowship through local meetings and email newsletters.

Our inclusion criteria were participants with a self-identified history of polio, defined as a febrile illness associated with acute muscle weakness followed by recovery with at least 15 years of stability [28]. Exclusion criteria were a contraindication to MRI

scan including a pacemaker or implanted medical devices or metallic fragments, severe claustrophobia, and those with confounding neurological diagnoses. We did not exclude those with implanted orthopedic metalwork as some polio survivors have internal joint fixation to enable locomotion, and the scans could continue safely with these in place [29]. Participants were prescreened against inclusion and exclusion criteria via telephone and were invited to take part in the study. During the study visit, further medical history was obtained, and a neurological examination was performed of the lower limbs by an experienced consultant neurophysiologist to assess tone, power (using MRC grading 0–5), and degree and pattern of wasting. The fatigue severity score (FSS) questionnaire validated on patients with neurological disease [30] was completed by participants, consisting of agreement with nine statements on a scale from 1 to 7, giving a score from 9 to 63.

For comparison of motor unit sizes to healthy controls, we used historically acquired data from a study involving healthy older participants collected 2–3 years prior using the same protocol and scan system. For that study, ethical approval was obtained from Newcastle University Faculty of Medical Sciences Ethics Committee (1852/525/2020). All polio survivors and healthy controls gave written informed consent prior to participation.

2.1 | Motor Unit MRI

The protocol for MUMRI has been described previously [2, 22]. Briefly, fibular nerve stimulation was paired with timed acquisition of PGSE images of the leg, with the slices centred at the thickest part of the calf. A 3 T Philips Achieva MR system (Best, the Netherlands) was combined with a flexible (FlexM, Philips) receiver coil pair positioned on either side of the leg. Several scans were performed (for detailed parameters see Table S1):

  • T1-weighted scan to assess muscle structure.
  • Dixon sequences [31] to obtain the fat fraction in the lower legs bilaterally.
  • MUMRI (PGSE) sequence setup scan during progressively increased stimulation strength through the range of muscle activation from subthreshold to supramaximal stimulation.
  • MUMRI “single motor unit scan” using a narrower stimulation current range to target the activation of a single motor unit (alternation) as assessed by visual inspection during the scan. This was then repeated twice at an even narrower stimulation current range in two stacks of 12 slices each (no slice gap). The overlap between the stacks was two slices and, in each stack, the most distal slice was unstimulated, resulting in 21 stimulated slices, imaging a continuous volume extending 210 mm along the lower limb.

Poliomyelitis is an asymmetric, patchy process, and subclinical changes can be found even in less-affected legs [32]. Based upon inspection of the structural T1-weighted scan, we targeted for motor unit imaging the side that showed neurogenic change in

the anterior compartment indicating involvement of poliomyelitis, but avoided a side if it had been completely replaced by fat leaving no muscle for investigation.

Peripheral nerve stimulation was performed using a pair of stimulating electrodes placed over the common fibular nerve at the fibular head. The electrodes were connected to a programmable stimulator (DS5; Digitimer, Ft. Lauderdale, Florida, USA) via coaxial cables with low pass filters (Minicircuits, New York, USA) at the Faraday cage. In all cases, the stimulator cathode was placed distal to the anode. The stimulus frequency was 1 Hz, with a bipolar square pulse of 0.3 ms duration. Stimulation current was progressively increased until a visible leg twitch was achieved. An initial MUMRI survey scan was then performed around this stimulation current in increments of 0.5 mA until a region of signal dropout was visible indicating the first recruitment of motor units, up to the point where the entire muscle image was seen to be saturated. This provided the current range required for initial motor unit recruitment through to stimulation of all available motor units. Detailed MU mapping scans were then conducted, focused on stimulation strengths where periods of alternation were seen during this setup scan. MUMRI scans were collected with 360 stimulated sequences, decrementing by increments of 0.03 mA over a total current range of 10.8 mA to identify single motor units on a single axial slice. To produce a map of the longitudinal extent of that motor unit, 125 stimulated sequences, decrementing by 0.03 mA (current range: 3.75 mA) were performed at 22 axial slices.

Motor units were identified based on alternation characteristics as described previously [2]. Regions of muscle were selected that exhibited “all or nothing” recruitment and did not have multiple levels of activation to suggest they were compounds of multiple motor units. The maximum and minimum Feret diameter (the maximum and minimum distance between two parallel lines restricting the motor unit outline) and crosssectional area were computed from single-slice acquisitions, and the shape complexity was calculated using the Hausdorff box-counting method using a MATLAB (Mathworks version r2021a) script [33]. To produce motor unit recruitment curves, the average brightness of the voxels in the anterior compartment of a single slice was measured across all stimulation strengths.

The Hausdorff box-counting method is a technique used to quantify the complexity of a shape by estimating its fractal dimension. This method involves overlaying a grid of boxes of a certain size over the shape and counting the number of boxes that contain part of the shape. The process is repeated with boxes of different sizes, and the relationship between the number of boxes and the size of the boxes is analyzed. This dimension provides a measure of the shape’s complexity, with higher values indicating more intricate structures [34].

Motor unit diameters and shape complexity scores were measured using previously described methods [2]. Motor unit diameters and shape complexity scores were compared to healthy participants aged > 65 using the two-sample t test (MATLAB ttest2 function). These were selected from existing unpublished data collected using the same scanning protocol.

2.2 | Structural Analysis

Dixon-sequence scans were segmented manually using ITKsnap, version 4.20 [35] into anterior (muscles supplied by the fibular nerve including tibialis anterior and extensor digitorum longus) and posterior (muscles supplied by the tibial nerve including gastrocnemius, soleus, and tibialis posterior) compartments. Segmentation was confirmed by a clinical radiologist (L.B.). The fat-free contractile muscle volume was calculated from Dixon sequences using ITKsnap.

Contractile muscle volume was correlated with MRC power grading for each lower limb by performing ordinal regression using Spearman’s ρ in SPSS v29 (IBM, Armonk, NY, USA).

3 | Results

Twelve participants were recruited based upon the inclusion criteria. Of these: one participant could not be scanned due to a flexion deformity preventing their leg safely fitting into the bore of the scanner; two showed no reliable motor unit activation at all; and one in whom data were lost prior to analysis. This left eight participants for analysis, with a mean age of 75 years (range 68–80), six of whom were female (Table 1). The mean FSS was 44.1 (27–55). Examination of lower limb MRC power rating ranged from 0 to 5 (Table 1).

The motor unit data were compared to 19 adults aged 65 years or older (n = 6 female, mean age 73.7, range 67–82). MRC and fatigue score measurements were not available in this retrospective comparison cohort.

3.1 | Muscle MRI Features

The structural images of the participants were heterogenous in appearance, with varying patterns of fat infiltration within, and across, different muscles of the anterior and posterior compartments (Figure 1). The degree of fatty infiltration was highly variable between and within subjects, with almost normal appearing muscles or muscle regions alongside areas of almost complete fatty infiltration.

Contractile muscle volume was also variable, with mean anterior compartment volume of 79 cm3, and ranging from 6.9 to 184 cm3. The muscle volume was moderately to strongly correlated with MRC power scores for the anterior (Spearman’s ρ 0.828 p < 0.0001) and posterior compartments (Spearman’s ρ 0.663 p = 0.001). Visual inspection of MRC power scores versus contractile muscle volume showed that while there was an association, there was overlap of contractile muscle volumes at different MRC power grading (Figure S1).

3.2 | Motor Unit Characteristics

The recruitment curves appeared continuous and sigmoid in three participants (P04, P05, P09) and discrete with large step increments in the remaining five (P03, P06, P07, P11, P12) (Figure 2). Alternation of single motor unit activity was seen in stimulation currents between 9.6 and 21.3 mA. Visual inspection

indicated there was no clear relationship between the shape of the recruitment curve and the MRC strength scores.

A single motor unit was identified in the anterior compartment of six participants, with two individuals demonstrating two and four units with distinct and noncontiguous patterns of recruitment, respectively (Figure 3). In healthy controls, a single motor unit was identified for each participant.

In the single-slice (two-dimensional) imaging, the mean and standard deviation (SD) of the motor unit maximum Feret diameter was 10.3 ± 3.1 mm (range 7.2–16.8 mm) compared to 8.4 ± 5.2 mm (range 2.8–20.5 mm) in controls (p = 0.34). The mean and SD of the motor unit minimum Feret diameter was 5.5 ± 2 mm (range 2.5–10.6 mm), compared to 3.7 ± 1.9 mm (range 2–6.8 mm) in controls (p = 0.01). The mean and SD motor unit area was 28.2 ± 18.8 mm2,

compared to 19.7 ± 16.2 mm2 in healthy controls (p = 0.24) (Table 2).

The mean and SD motor unit shape complexity as computed using the Hausdorff metric was 0.59 ± 0.12 compared to 0.45 ± 0.2 in controls. There was a significant difference when comparing polio survivors to the controls (p = 0.03).

To further explore the relationship between the motor unit morphologies and the macroscopic tissue volume of the limb in polio survivors, we assessed the correlation between contractile muscle volume and the motor unit shape complexity measure, and no correlation was found (Spearman’s ρ = 0.51, p = 0.09).

In the 22-slice (three-dimensional) imaging, six participants were excluded from analysis. Two of these showed excessive spontaneous activity at rest, one showed multiple motor units

that overlapped in activation current and territory, and in three more the motor unit showed insufficient activations to produce a consistent motor unit profile between slices. Of the remaining two participants, one showed two discrete motor units while another showed a single motor unit (Figure 4). Motor units extended between 6 and 10 cm longitudinally and the maximum Feret dimensions across all slices ranged from 3.6 to 16.1 mm (Table 3).

4 | Discussion

Using motor unit MRI combined with in-scanner nerve stimulation we show that the motor units in survivors of polio have a similar maximum Feret diameter and cross-sectional area to controls, but both the minimum Feret diameter and shape complexity were significantly increased. This suggests that

reinnervation occurs within the original motor unit territory, results in an increased fiber density, and that this process is not uniform across the motor unit.

The implication of this limited spatial area within which reinnervation occurs is clear. As motor units are lost in a neurogenic disease, the surviving units are able to extend collateral nerve

branches to reinnervate fibers within their immediate territory, but these do not extend to reinnervate distant fibers. With limited motor unit loss there is sufficient overlap that all of the denervated fibers lie within a surviving motor unit’s territory, and potentially can be reinnervated. However, with further motor unit loss, regions of muscle containing no overlapping survivors will occur, and further motor unit loss will result in permanent muscle fiber denervation and ultimately fatty replacement. This insular remodeling phenomenon may be the reason that neurogenic “islands” have been shown in a number of muscle MRI studies of neurogenic (but not myopathic) diseases [36]. We have highlighted a number of muscle MRI scans with patchy, heterogenous changes across muscle groups, including some with the same pattern of neuromuscular “islands.” Indeed one of the participants showed a single motor unit which alternated with no overlapping motor units (Figure 4C), demonstrating that all of the muscle fibers in that region belonged to a single motor unit. Despite this, the level of wasting of a muscle, representing the likely degree of polio involvement, was not correlated with measures of motor unit shape complexity.

This technique reveals an important research direction in assessing the neurogenic motor unit. Since we are able to reliably activate a motor unit and detect its location and shape within the muscle, MUMRI may be useful as a longitudinal assessment of a motor unit’s health [20, 37].

We were able to obtain 3D images of only three motor units in two participants, which was a lower yield than our previous study in healthy participants [22]. Partly this was due to the difficulty in identifying discrete, non-overlapping motor units in a given slice, and partly due to difficulties in identifying the same motor unit in adjacent slices. This may be due to the activation characteristics of neurogenic motor units, which show a higher relative spread of threshold variability compared to healthy units [38], and therefore will alternate over a wider current range than healthy units, producing fewer activations. Despite the low yield, the longitudinal extent of the imaged units is comparable to those in healthy controls (mean 8.0 ± 3.8 cm).

Our study has important limitations. While we identified our polio survivor cohort from the British Polio Fellowship and selected according to established criteria, these diagnoses are historical by 60 or more years. Polio itself is a heterogenous disease, and the intervening duration will further contribute to the

heterogeneity of this population. This was seen in the variability of involvement on structural MRI sequences, showing differing degrees of fatty infiltration in different compartments, resulting in reduced contractile muscle volume which in turn was associated with reduced power rating.

There were important sex differences between our polio survivors and control cohort, with a greater proportion of female participants in the polio cohort (6/8) than controls (6/18). Important differences in muscle properties are seen between sexes, with females showing lower MUP amplitudes and higher firing rates than males [39], as well as a higher motor unit count [40], and this may have had a bearing on the differences between cohorts.

While we were able to identify single motor units in 8 out of 12 participants, a fixed-flexion deformity prevented one individual from fitting into the bore of the scanner, and no motor unit activity could be found in two participants, potentially limiting the utility of this technique in late-stage neurogenic diseases.

Despite longstanding efforts to eradicate the disease, polio remains prevalent in several regions of the world, most notably Pakistan and Afghanistan. With increasing global migration and vaccine hesitancy, the number of polio cases is likely to rise [41]. While our study population was exclusively UK patients who had contracted the disease during the polio outbreaks in the 1950s and 60s, a new group of far younger survivors of polio is being recognized who also need accurate diagnosis and monitoring. We believe that MUMRI may have a role alongside conventional EMG in achieving this.

Living Well With Post Polio As We Age

LIVING WELL WITH POST-POLIO AS WE AGE Nikki Wingerson, MSW, Ph.D., October 26, 2023

 

I. Introduction At the Ohio Polio Network 30th Anniversary and 2023 Conference, I was asked, as a mental health professional and member of the OPN Advisory Board, to write an article for OPN. I am an aging 77-year-old who has lived 38 years with Post-Polio Syndrome, so I decided to selectively explore evidence-based literature on both polio and aging to ultimately address living well with Post-Polio as we age. This article provides what I hope is relevant information for any reader about polio and its impacts; physiological changes that come with normal aging; challenges of aging with Post-Polio; suggested adaptations to aging and PostPolio; and a few reflections derived from this exploration.

 

II. Poliomyelitis

 

Poliomyelitis is the virus that causes the disease called polio. The virus is capable of attacking nerves in the spinal cord or brain stem, paralyzing muscles related to breathing, speaking, swallowing, and moving one’s limbs. The virus attacks nerves with a shotgun scatter effect, such that the resulting physical symptoms manifest unevenly: One leg might be capable of climbing stairs, the other not. Vaccination against polio since 1955 has eradicated the disease in the United States and in virtually much of the world.

 

III. Late Effects of Polio and Post-Polio Syndrome: Definitions, Causation, Diagnosis

 

The Late Effects of Polio (LEoP) is the term for symptoms related to a person having had polio. These symptoms include fatigue; decreased muscle strength and endurance; pain; breathing or swallowing or speech problems; sleep problems; and physical symptoms, such as joint problems and scoliosis. [1]

 

The LEoP are not associated with re-infection by the polio virus, but rather, with a greater loss of motor neurons than is typical in the normal aging process. Loss of motor neurons leads to increased muscle weakness. Reduced muscle tissue leads to muscle fatigue and pain. Weakened limbs can lead to reduced weight-bearing activity and reduced bone density. Postural abnormalities resulting from polio can lead to pain, and/or sleep or breathing problems. Increased stress on joints can lead to arthritis and pain. [1]

 

Post-Polio Syndrome (PPS) is a sub-category of LEoP and is a diagnosable neurological condition for those who have had polio, with or without paralysis. PPS is diagnosed 1) when new pain and/or weakness occurs following recovery from the acute illness and 10+ years without new symptoms; 2) when these new symptoms continue for at least one year; and 3) when there is no other clinical explanation for the new symptoms. [1] Nerve Conduction Studies and EMG tests, which measure muscle electrical activity, are sometimes useful in identifying the bases for new symptoms. [6]

 

The symptoms of Post-Polio Syndrome typically appear 15 to 30 years after recovery from the acute illness. [9] PPS symptoms have been “associated with the degree of residual weakness immediately following [patient] polio infections.” [11] However, PPS symptoms usually are not as severe as those experienced following the acute illness. [6] Along with the symptoms of LEoP noted above, other reported symptoms of PPS include cold intolerance and restless leg syndrome. [9]

 

The prevalence of PPS among polio survivors is estimated to be 25% – 40%, according to the CDC. [2] Risk factors for PPS include female sex, permanent disability caused by motor neuron damage, respiratory symptoms, muscle overuse and underuse, aging, and “immunologic mechanisms.” [9] The severity of, and degree of recovery from, symptoms caused by the acute illness determine the risk of developing PPS. [9] “As deficits at the end of the disease increase, the probability of experiencing post-polio symptoms increases.” [11]

 

There are three major theories for the cause of PPS. [8] The prevailing theory for the origin of PPS is based on the fact that recovery from polio involves the body creating new connections between surviving nerve cells and muscles, this to compensate for nerves damaged by the virus. [6] Over time, these compensatory nerve cells or extra nerve branches breakdown due to inflammation, injury, illness, one’s immune system, periods of inactivity, and normal aging. [6] This breakdown can occur anytime [11]

 

A second theory for the existence of PPS is the persistence of polio infection in the brain and spinal cord. [6] Several studies have shown the existence of polio virus genome fragments in the cerebrospinal fluid of PPS patients. [8]

 

A third theory for the cause of PPS is delayed immune response to the polio virus, leading to chronic inflammation and, thus, persistent symptoms of polio. [8] One study explicitly states that PPS symptoms were attributed to neuronal loss over time with inflammatory mechanisms, but “without any convincing evidence of viral reactivation.” [9]

 

IV. Normal Physiological Changes with Aging

 

With the increased experience of increased age comes wisdom. At the same time, normal aging also poses physiologic limitations apart from those experienced due to PPS. [5]

 

The Washington Post on October 15, 2023 included an online article by Judith Graham, “What’s normal for the body and brain as we age? An expert weighs in.” The information Graham provides is based on an evidence-based new book by Rosanne Leipzig, “Honest Aging: An Insider’s Guide to the Second Half of Life.” Leipzig is a physician and vice chair for education at the Brookdale Department of Geriatrics and Palliative Medicine at the Ichan School of Medicine at Mount Sinai in New York. Graham describes Leipzig’s book as “the most comprehensive examination of what to expect in later life I’ve come across in a dozen years covering aging.” [3]

 

In her article, Graham notes that explaining how we change with aging is difficult, because the aging process is gradual, decadeslong, and influenced by one’s behaviors, as well as one’s economic and social circumstances, and the like. There are common and predictable physiological changes, but the sequence and timing of these changes vary from one person to the next. [3]

 

Graham delineates some of the age-related issues that Leipzig describes in her book. Importantly, she includes why these changes occur, not covered here due to space constraints. Older people often present with different symptoms than do younger people when they have the same illness, and they often react differently to the same medication. Indeed, due to physiologic changes with aging, older people often require lower doses of medications which they have taken for years. Older people more frequently experience cognitive changes related to medications and illness than do younger people. These cognitive changes are normal and not a sign of dementia. Also, due to physiologic changes with aging, older people experience less musculoskeletal flexibility; weakened tendons and ligaments; reduced joint range-of-motion; reduced height; decreased muscle mass, strength, and energy; and reduced sense of hunger, thirst, taste, smell, and appetite. Older people require more energy for daily tasks and more protein for maintaining and building muscle. [3]

 

With aging, balance is compromised due to changes in the inner ear, the brain, and the vestibular system. Compromised balance, along with reduced bone density, leads to more frequent falls and fractures among the aging. Older people require more light to read, and more time to adjust to changes in available light. They experience difficulty in hearing, especially higher-frequency sounds and rapid speech. They find it more difficult to fall or stay asleep. Finally, people’s information-processing and reaction times slow with aging, while new learning, multitasking, and word-finding become more difficult. [3]

 

V. Aging with Post-Polio

 

In general, conditions which impact the aging population, including age-related chronic diseases, such as high blood pressure, diabetes, heart disease, COPD, and osteoporosis, may occur “more frequently, and at younger ages” among those who are physically disabled. [10] This is because health issues and barriers to maintaining health are often increased in the physically disabled population. Thus, those who are aging as well as physically disabled “need preventive services and at younger ages.” [10]

 

New symptoms in aging polio survivors might include pain at rest; cold intolerance; issues related to standing, walking, and climbing stairs, which increase both fall risk and accessibility issues. [4] PPS patients lament the lack of accessible public spaces, new lack of accessibility to friends’ homes, and the cost of purchasing assistive technology and services. [2] In one study, research participants were surprised at the nature of their fatigue, as it seemed unrelated to their physical effort. Some expressed surprise that they could no longer rely on parts of their body which they had previously relied upon. [4] All of these new symptoms and issues can lead to greater social isolation.

 

Psychological features might include reliving original polio trauma; recognition that former coping behaviors, such as “blending in,” no longer work; shame; lack of motivation; and fear of injury. [4] Fatigue due to PPS must be distinguished from fatigue due depression. Risk factors for depression include one’s previous illness experience, attitude towards disability, previous coping style, nature of physical changes, and degree of increased impairment, as well as the quality of one’s support. [12]

 

Interestingly, one study of aging post-polios found “modest increased weakness which may be commensurate with normal age.” These researchers found a discrepancy between patient experience with growing weakness and actual measurements of strength and neuronal loss, the measurements indicating “modest declines.” This discrepancy was considered likely due to “increased sensitivity due to their disease experiences… they lost so much strength at the time of their illness that any change is very noticeable to them.” [11]

 

VI. Adaptations to Aging and Post-Polio Syndrome

 

According to Graham, Rosanne Leipzig, in her evidence-based new book, recommends the following for adapting to age-related changes: Seek medical attention for sudden changes in functioning. Regularly ask your physician what each of your medications is for, and whether or not continued usage and dosages are currently appropriate. Engage in physical activity and in balance and resistance exercises. Stay well-hydrated – “Drink liquids even when you aren’t thirsty” – and eat sufficient protein. Have your eyes checked annually. Use hearing aids, if you find keeping up with conversation difficult. Two to 3 hours before bedtime, avoid exercise, alcohol, and heavy meals. Reduce multitasking and pace yourself. [3]

 

Post-Polio Syndrome management includes energy conservation; pacing of physical activities to avoid overuse; frequent rest periods; avoidance of stress; avoidance of cold temperatures; avoidance of pain with exercise; use of assistive devices; surgeries for joint repair; respiratory, occupational, and/or speech therapies; exercise physiology; podiatric care; dietetic consultation for weight management; use of mental health specialists and support groups to meet emotional needs; and planning ahead for one’s every move. [1] [2] [4]

 

The theory of PPS causation as an immune response to the polio virus leading to chronic inflammation proposes “treatment with immune modulators as means of combating the chronic inflammation.” [8] Management might include immunoglobulin to reduce “proinflammatory cytokines present in the cerebrospinal fluid of the spinal cord.” [9]

 

Aging is “often seen through the lens of the biomedical model of health, which focuses on preventing and curing medical problems causing disability.” Disability is often seen through the lens of the “social model of health, which focuses on building inclusive environments and eliminating systemic barriers.” [2] Both lenses are needed for clear vision towards patient quality of life. Living well with Post-Polio as we age requires an individualized, goal-oriented, comprehensive, interdisciplinary approach, with focus on empowerment and positive self-evaluation. [4]

 

VII. A Few Reflections

 

Undoubtedly, there is overlap in symptoms of PPS and aging. Either may aggravate the other. Both PPS and aging populations may experience an increased sense of vulnerability and difficulty accepting help. We aging Post-Polios must trust and honor what our bodies tell us about our need to make adaptations, regardless of how others perceive or judge our capabilities, or what tests might indicate about our strength.

 

Likewise, there is overlap in adaptations to PPS and aging. The good news is that those with PPS likely have already devised ways to adapt to changes in their physical function prior to experiencing the effects of advanced aging. In fact, they might consider themselves expert at adaptation.

 

As a polio survivor, I used to be able to conceal my left arm paralysis, the only polio residual I had for years. I was encouraged to find ways to do physically most everything that my peers could do. I was fortunate, for the most part, to be able to “blend in.” Then, at the age of 39, about 35 years after I had polio, I began having trouble climbing stairs. An orthopedic specialist described my legs as “misaligned,” in that polio had impacted muscular function in each leg differently. I had not known my legs were impacted at all.

 

I was informed that I had Post-Polio Syndrome. I gradually made adjustments. While I had to make adaptations that my non-polio peers did not have to make, I was exceedingly fortunate in having much remaining physical ability, adequate supports, and the financial means to hire help or buy equipment as needed.

 

Now I use a railing and climb stairs one at a time, since only one particular leg can lift me up each stair. I use a sling to support my limp arm. I’ve had to ask for assistance like never before. The difference for me now is that as I look around, I see that I have company among my aging non-polio friends in the use of assistive devices and asking for assistance. I “blend in,” but in a different way now. Aging has become a common leveler.

 

If age makes common bedfellows of us all, then I am in good company. Perhaps I can let go of past capacities with a bit more grace, if I view my increasing limitations from that perspective.

 

Living well with Post-Polio as we age requires that each of us find our own unique way to capitalize on our strengths and move forward, just as we always have. We need to take seriously suggested adaptations to PPS and aging, such as those noted above. That said, I rest my case and will adjourn for my regularly scheduled nap.

Poliovirus detection in Montreal, New York, London, Israel in wastewater continue in 2023. Polio outbreak information is fact-checked by medical professionals.

Polio Outbreaks March 2023

Poliovirus (Poliomyelitis) has been recently confirmed in wastewater and ground samples in non-endemic countries in Africa, the Americas, Asia, Canada, Europe, India, Israel, the United Kingdom, and New York (NY).

To notify the international community, the U.S. Centers for Disease Control and Prevention (CDC) issued an updated Global Polio Alert – Level 2, Practice Enhanced Precautions notice on March 7, 2023, regarding polio outbreaks and poliovirus detections in various countries. As of March 10, 2023, the New York Department of Health informed New Yorkers planning to visit Israel in 2023 and other countries with circulating poliovirus to confirm their polio immunization status prior to traveling abroad.

On September 13, 2022, the U.S. was added to a list of about thirty countries where circulating vaccine-derived poliovirus (cVDPV) was recently identified. On September 1, 2022, the CDC’s Clinician Outreach and Communication Activity Call presented: How to Recognize and Report Polio and Reinforce Routine Childhood Polio Vaccination.

As of March 2, 2023, there has been 1 confirmed polio (acute flaccid paralysis) case and 7 reports of patients under investigation in the U.S. (Washington) during 2023. There have been 723 confirmed polio cases in the U.S. since August 2014. An interactive timeline traces polio outbreaks from 1580 B.C. to 2022.

WHO Polio Public Health Emergency of International Concern 2023

On February 2, 2023, the World Health Organization (WHO) confirmed the spread of poliovirus remained a Public Health Emergency of International Concern (PHEIC) concerning Wild poliovirus type 1 (WPV1) and Circulating vaccine-derived poliovirus and recommended the extension of Temporary Recommendations for three months. This WHO issued a report (EB152/19, Dec. 2022) on implementing the Strategic Action Plan on Polio Vaccine Transition (2018–2023). In addition, the polio-endemic countries of Afghanistan and Pakistan have been associated with recent polio outbreaks in other countries, according to the Global Polio Eradication Initiative (GPEI).

Poliovirus Wastewater Detections 2023

Related poliovirus type 2 (PV2) isolates were identified in sewage samples collected in Canada, London, Israel, and New York in 2022. As a result, the U.S. CDC announced on November 30, 2022, that it would expand wastewater testing in the U.S. Dr. José R. Romero, Director of CDC’s National Center for Immunization and Respiratory Diseases, indicated that poliovirus testing would continue into early 2023.

Poliovirus Detroit, Michigan

The U.S. CDC announced plans to collect wastewater samples in communities near Detroit, Michigan. Preliminary testing will last at least four months. Oakland County, Michigan’s population is about 1.2 million. On August 23, 2022, Michigan reported 31% of young children were overdue for routine vaccinations, including polio.

Poliovirus Philadelphia, Pennsylvania

The U.S. CDC announced it would begin collecting wastewater samples from Chester County, with a population of about 500,000 near Philadelphia, PA, for analysis at CDC’s polio laboratory.

Poliovirus New York March 2023

As of March 8, 2023, the U.S. Centers for Disease Control and Prevention (CDC) and the State of New York confirmed sequencing analysis confirmed the presence of circulating vaccine-derived poliovirus (cVDPV2) in 100 samples collected genetically linked to a polio patient (Acute flaccid myelitis) identified in July 2022 in Rockland County, NY, signaling its continued circulation and a health risk to residents.

To enhance local detections, the New York State Department of Health announced on January 23, 2023, that it received $21.6 million in funding to expand its wastewater surveillance and infectious disease monitoring capabilities. NY’s wastewater network reaches all 62 New York counties and, during 2023, will increase the number of participating sewer sheds from 125 to over 215, reaching 16 million New Yorkers, about 81% of the population served by public sewer systems.

Beginning in April 2022, genetically related poliovirus has been detected in wastewater samples collected in Rockland County, Orange County, Sullivan County, Nassau County, Brooklyn (Kings County), and Queens County. On September 28, 2022, a ‘Declaration of an Imminent Threat to Public Health for poliovirus’ was issued by Mary T. Bassett, M.D., M.P.H. Commissioner of Health, NY.

In response to these poliovirus wastewater findings, the Governor of NY, Kathy Hochul, announced on October 9, 2022, she extended Executive Order 21.1, expanding the vaccination authorities for certain NY health providers. And New York State issued HEALTH ADVISORY Update #3 Regarding Poliovirus, which says unvaccinated New Yorkers or those not up to date with immunizations who live, work, go to school in or visit Rockland County, Orange County, New York City, Sullivan County, and Nassau County are at risk of contracting the paralytic disease and should speak with their healthcare provider regarding polio vaccination options.

As of March 2023, the New York Health Department states that under specific situations, a one-lifetime booster dose of IPV should be offered to adults who have previously completed their polio vaccination series and are at the highest risk of infection. Areas considered to have community transmission of poliovirus include those where poliovirus has been repeatedly detected in wastewater. As of January 27, 2023, polio booster doses are not recommended for individuals traveling to the New York City metropolitan area, including Rockland, Orange, or Sullivan Counties, merely because of their travel status.

Polio in the Americas

As of March 2023, the Pan American Health Organization (PAHO) published AFP Surveillance Data segmented by Country for 2022.

Poliovirus Montreal Canada

On December 23, 2022, the Canada IHR National Focal Point reported detecting a vaccine-derived poliovirus type 2 (VDPV2) in various wastewater samples collected in August 2022 from a wastewater treatment plant and a target site in the city of Montreal, Quebec. Genetic sequencing confirmed it was linked to the cVDPV2 recently detected in New York. Additionally, in January 2023, two cVDPV2-positive environmental samples were collected in Canada. As of January 30, 2023, there have been no confirmed or suspected cases of acute flaccid paralysis (AFP) being investigated in the affected Canadian jurisdiction in 2022 – 2023.

Polio Israel 2023

As of March 10, 2023, Israel has been confirmed with both cVDPV2 and cVDPV3, and there is evidence of the continued existence of poliovirus in the wastewater sewage of many localities. In early March 2023, JPost reported the Health Ministry announced that an unvaccinated child from the Safed region in Galilee arrived at Ziv Medical Center and was found positive for (cVDPV2) acute flaccid paralysis (AFP). On March 2, 2023, the Times of Israel reported the Health Ministry confirmed three other children tested positive for poliovirus.

Poliovirus London

The UK Health Security Agency (UKHSA) declared a “national incident” in June 2022 after poliovirus detection in sewage in London, England. Detection of 118 genetically linked poliovirus isolates related to the serotype 2 Sabin vaccine strain collected in 2022, reported The BMJ and The Lancet. In addition, vaccine-derived poliovirus type 2 isolates environmental samples were found in several north and east London boroughs that were genetically linked to a polio case reported in New York and Israel.

Acute Flaccid Myelitis Polio-Like Virus

The U.S. CDC reported on March 2, 2023, there has been one confirmed AFM case in 2023 out of 7 reports of patients under investigation. AFM is an uncommon but serious neurologic condition caused by viruses, including enteroviruses (EV-D68). It affects the nervous system, specifically the area of the spinal cord called gray matter, which causes the muscles and reflexes in the body to become weak.

During 2022, the CDC reported 43 confirmed AFM cases in 24 states, indicating about a 35% increase from 2021. There have been 723 confirmed cases (children) since the CDC began tracking AFM in August 2014.

Acute Flaccid Paralysis

Acute Flaccid Paralysis (AFP) surveillance is the standard for detecting cases of poliomyelitis in anyone under 15 years of age. For AFP surveillance standards, please visit the WHO-recommended surveillance standard of poliomyelitis. Date of last update: 10/09/2022.

Post-Polio Syndrome

As polio survivors progress through life, a significant proportion develops neurological symptoms known as Post-Polio Syndrome (PPS), says the U.S. NIH. Characterized by new, gradual, and progressive muscle weakness and wasting, difficulty swallowing, joint or muscle pain, and general fatigue after being stable for many years, the non-contagious PPS typically develops 15 to 40 years after people have recovered from polio.

The first medical reports of PPS appeared in France in 1875. Further research published in the 1950s identified significant damage to nerve cells within the spinal cord. However, as the UK-based Polio Survivors Network concludes, PPS has no set pattern of nerve damage. The U.S. CDC posts additional clinical and diagnostic information about poliovirus infection as of August 10, 2022.

Poliovirus Shedding

The WHO, the UK Health Services Agency, the European CDC, and the U.S. National Institutes of Health (NIH) say three types of vaccines can prevent polio but they may indirectly enable virus shedding. However, research demonstrates that poliovirus transmission predominantly follows the oral-fecal route. In addition, concerns remain about the potential for persistent transmission of OPV viruses, as these viruses are known to revert toward wild-type neurovirulence.

Polio Vaccines Approved

Polio is a vaccine-preventable disease, says the U.S. CDC. For the latest polio vaccine information, visit this PrecisionVaccinations webpage.

Covid Vaccines The Polio Survivor

 

Covid-19 vaccines & the polio survivor

 

The recent pandemic has thrown into sharp relief the crucial part that vaccines can play in  subduing / mitigating and halting the spread of viruses whether that be the polio virus, yellow  fever or in this case the corona virus COVID-19. However, with the availability of social  media many untruths, falsehood and lies are spreading regarding who should or not be  vaccinated. This paper draws on medical sources and journals around the world and sets out  to help explain where polio Survivors fall, in whether they should be vaccinated or not. It  purely applies to the polio Survivor but does make reference to those who may have co

morbidity.

In researching this paper and contacting medical authorities one thing has become abundantly  clear – the power of the pharma companies and the fear of running foul of them or being  sued.

The one clear fact, from all the regulatory bodies, European Medical Agency (EU), Medical  Regulatory Health Authority (UK), Centre for Disease Control (EU/USA) Federal Food &  Drug Administration (USA) and the equivalent bodies in Australasia is that whatever the risk  from some vaccines might be, remaining unvaccinated and contracting COVID-19 is far  more dangerous and in 1:800 cases will lead to death. Many Covid Survivors will go on to  having serious long term affects that in many instances will be life changing.

The Process for Regulatory Approval:-

All medicines must be approved by the medical/drug licensing authority of the country or  group of countries before they can be widely used in either oral or injectable solution, there  are some exceptions to this in certain cases where fast tracking is needed. The Covid  vaccines are no different. A pharma company will develop a new treatment and then submit  it together with all supporting documentation for scrutiny by the licensing authority. Part of  the documentation will be the results of trials in the tertiary stage for human volunteers. In  certain cases, such as cancers the pharma company will recruit those suffering from the  disease and put these volunteers through a double-blind test, meaning some will get the  drugs, others not. In both cases neither the doctors involved, nor patients will know which  they received until results are revealed. This same double-blind procedure has been used in  all the COVID-19 vaccines currently licensed. However, there was one important difference  these volunteers were recruited by self referral and were drawn from across a cross section of  society. Medical histories of the volunteers were taken to ensure their safety but from what  has been reported no specific groups were targeted for inclusion – although some such as  pregnant women were excluded. Our enquiries have failed to reveal whether the tests  included any polio Survivors. However, statistically if taking a cross section of society, one  would have thought it would have done.

Post Regulatory Approval

After approval procedure and the drug / vaccine etc goes into use a reporting system, called  the yellow card system, is initiated so that doctors, medical authorities and others may report  adverse effects. This how the blood clotting instances came to light and which have attracted  so much attention. It should be noted that 2 cases of blood clotting have also been reported  with the Pfizer vaccine, but the majority are among those who received the AstraZeneca  Oxford (now renamed Vaxzevria vaccine) and the Johnson & Johnson (branded Janssen in  Europe) vaccine. What are the facts?

Blood Clots – The Facts:

Blood clots, including the extremely rare cerebral sinus thrombosis (CST), occur in  unvaccinated people as well as those who have had Covid and/or a Covid vaccine.

Cases that may be linked to vaccination typically occur 5 to 28 days after the first dose of  Oxford/AZ . The risk of dying from one is in the order of one in a million. There have been 6  cases among the Johnson & Johnson cohort out of 6.8 million doses administered, including  one death and one still critically ill. The incidence rate in the AZ vaccine is statistically  similar. All those who have been affected, to date (14/5/21), are female under the age of 50.  Interestingly these two vaccines are produced on the same technology and micro biology as  the Polio vaccines that have been administered to tens of millions around the world with no  apparent side effects reported in decades.

Symptoms of CST include a headache lasting more than four days after vaccination that is  persistent, worse on coughing and straining and not relieved by simple painkillers. Others  include blurred vision, stroke-like symptoms and pain in the ear/face.

Clots outside the brain (deep vein thrombosis and pulmonary embolus) can cause swelling of  the leg, calf pain, shortness of breath, chest discomfort and coughing up blood. Low platelet levels (another rare side effect associated with CST) may cause unusual  bruising and a characteristic pinprick reddish/purplish rash that does not blanch with  pressure (use the side of a glass).

The fact that these side effects have been reported does not show the vaccines are failing,  according to medical sources, rather it demonstrates how robust the “yellow card” reporting  system is in flagging up problems.

Who should and should not get the COVID-19 vaccine? – Yale Medical School

COVID-19 can cause severe medical complications and lead to death. There is no way to know how  COVID-19 will affect individuals. A person who contracts COVID-19, can spread the disease to  family, friends, and others, especially the elderly with the risk of much higher mortality, 1:800, than  from vaccine complications.

Getting a COVID-19 vaccine helps protect the recipient and others around them from COVID-19,  particularly people at increased risk of severe illness from COVID-19.

Can people with allergies get the COVID-19 vaccine? Yes, with 2 exceptions:

∙ People with a severe allergic reaction (anaphylaxis) to any component of the COVID-19  vaccine should NOT receive the vaccine.

∙ People with a severe allergic reaction (anaphylaxis) to any vaccine or injectable  (intramuscular or intravenous) medication should consult with their caring physician, or the  providing authority to assess risk before receiving any COVID-19 vaccine.

Everyone else with severe allergic reactions to foods, oral medications, latex, pets, insects, and  environmental triggers may get vaccinated.

People with severe allergies require a 30-minute observation period after vaccination, while all others  must be observed for 15 minutes. Vaccine clinics have safety protocols in place to respond to any  adverse reactions, i.e. Epipens/Adrenaline.

If I am pregnant or breastfeeding? A pregnant or breastfeeding person may choose to be  vaccinated against COVID-19. The American College of Obstetricians and Gynaecologists (ACOG)  recommends that the COVID-19 vaccine should not be withheld from pregnant or breastfeeding  individuals.

There are limited data about the safety of COVID-19 vaccines for people who are pregnant. Pregnant  people are at increased risk for severe illness from COVID-19 and may be at risk for adverse  pregnancy outcomes. If pregnant and in work places, the individual is at a high risk for COVID-19 infection, the benefits and risks of the vaccine should be discussed with the relevant healthcare  provider.

Currently, there are no data on the safety of COVID-19 vaccines in breastfeeding people or on the  effects of mRNA vaccines on the breastfed infant or on milk production/excretion, however mRNA  vaccines are not thought to be a risk to the breastfeeding infant. Although definitive data are not yet  available, maternal antibodies passed to the infant via breastmilk may provide protection as seen with  antibodies to other viruses. Breastfeeding people should discuss the benefits and risks of the vaccine  with their healthcare provider.

Is the vaccine as effective in people with suppressed immune systems? Specific efficacy  and safety data are not yet available for people with immunosuppression due to medications or  chronic illness. People with autoimmune conditions or who are immunocompromised are not  excluded from getting the vaccine. Those who are vaccinated should be guided on the potential for  reduced immune responses and the need to continue to follow all current guidance to protect  themselves against COVID-19. If an individual is immunocompromised or has an autoimmune  disease, this is a matter for discussion and decision between the individual and their doctor or other  healthcare provider.

A paper published on 13th April 2021 by APNEN (a Portuguese medical body) states:- “It is not uncommon for patients with autoimmune disease to have doubts about vaccination.  Should I get vaccinated? Is any type of vaccine compatible? What are the  recommendations? To address these and other doubts we spoke with Dr. Herval Ribeiro  Soares Neto, who explained the importance of vaccination in those dealing with a chronic  disease or condition such as Multiple Sclerosis (MS), an autoimmune progressive disease in  which the immune system attacks the central nervous system (brain & spinal cord).

He said “There are several myths and arguments against vaccination. And when it comes to  immunisation in autoimmune diseases, the misinformation is usually greater. Therefore, first  of all, we need to reinforce that the gain with immunisation, in general, is very large,  exceeding individual prevention.”

Can children get the COVID-19 vaccine? Not yet. No vaccine can be widely given to children  until it has been tested in them. The current mRNA COVID-19 vaccines were not studied or approved  in children younger than 16 years of age.

The Pfizer mRNA vaccine is authorized for people 16 years and older. The Moderna mRNA vaccine  is authorized for people 18 years and older.

Should I get the COVID-19 vaccine even if I’ve already had COVID-19? The extent to  which antibodies that develop in response to COVID-19 infection are protective is still under study. If  these antibodies are protective, it’s not known what antibody levels are needed to protect against reinfection. Therefore, even those who previously had COVID-19 can and should receive the COVID 19 vaccine.

I was recently diagnosed with COVID-19 can I receive the vaccine? Yes, for Dose #1  you can be vaccinated four weeks after onset of symptoms or a positive test (whichever is earlier). For  Dose #2 you may be vaccinated after you have completed your isolation period.

Isolation is for 10 days or 10 days plus 24 hours with no fever and an improvement in symptoms.

OTHER OPINIONS: –

As stated above the majority of those approached did not want their opinions either quoted or  attributable. However, Dr Peter Brauer, an honorary EPU Member and author for many years on  Post-Polio Sequalae (ICD10-CM-B91) and Post-Polio Myellitic Syndrome (ICD10-CM-G14) has  informed us that “ According to my continual research into vaccines I , according to my  opinion, do not recommend vector vaccines such as Astra Zeneca, Sputnik V and

Johson & Johnson for polio survivors, The alternatives would be mRNA vaccines such  as Biontech-Pfizer and Moderna. Permission for the mRNA vaccine of Curevac is  pending.”

Dr Richard Bruno, another long-standing researcher and author on the subject said “I  reviewed the manufacturer’s data bases and the Centre for Disease Control (USA), and then did a survey of the Post Polio Coffee House. No adverse effects with Pfizer or Moderna in  polio Survivors. Just sore arm, some fever. .Polio Survivors not more likely to get blood  clots so at same risk as general population re AstraZeneca”

Peter Thwaites who runs Polio Warriors and spends large part of his time in the Philippines said “I gather from a conversation I had with a PPS specialist that any of the vaccines are  suitable for polio Survivors and the fuss about the Johnson/AstraZeneca vaccines is  completely unnecessary but the EMA/MHRA won’t commit.”

CONCLUSION:-

When it was realised that vaccines were not years away but months, bodies such as the  European Commission, European Medical Agency, Centres for Disease Control, Federal  Drug Administration said they would run co-ordinated and co-ordinating roles. For example, in Europe central purchasing and distribution, this has fallen apart for many reasons, part  political, part logistical, part nationalistic. The fact is that all the bodies have declared these  vaccines safe and effective and it is only now in these extremely rare blood clotting events  that restrictions have been imposed. Even then different national opinions and maybe  prejudices come into play. For example, in Ireland the AstraZeneca vaccine will only be  given to those over 60, in the UK over 30.

As far as polio Survivors are concerned there is little or no evidence either way as to which  vaccine suits them best. In the main opinion is extremely scarce and divided. From our research, and opinions submitted we can find no greater risk to polio Survivors from the  vaccines than to the general population, including blood clotting.

Variant of COVID Virus

Variant of Covid Virus

– Kindly shared with us by Eddie Bollenbach M.A. biology

You have probably heard of the new variant of COVID

virus in the United Kingdom and also another mutant

strain in South Africa with similar mutations to the UK

variant. Let’s constrain ourselves to the UK mutant.

The reproductive number or Ro of the wild strain is

1.1 which means 10 infected people will typically

infect 11 others. It is believed that the reproductive

number Ro of the mutant strain is 1.5, which by division you can find that the new  virus seems 70% more infectious. 10 people will most commonly infect 15 people.

The difference in infectivity is not enough to mean we cannot control the virus by  mask-wearing, social distancing, and hand washing. It can be handled.

Now, since the genetic code of the new variant differs in 6 places in the spike  protein, but USA Today says 8 places, the result is that two amino acids in the  spike protein are different from the wild type. A protein is a long chain of amino  acids linearly bonded to one another. Then this long line of amino acids folds a  couple of times to give us the shape of the protein. A change of 2 amino acids in  the spike protein will result in a slightly different shape for the spike protein. In  this new variant, there are a whopping 17 new mutations altogether.

Since the shape of the spike protein matters because it is the target of antibodies  induced by vaccination the concern arises regarding the antibody shape combining  with the new spike protein shape.

The good news is vaccinologists believe the vaccines will still be effective and  work. Continuing research is going on now in Britain to measure this.

This variant will soon be all over the world if its Ro is higher than that of the wild  strain. The US hasn’t closed its border to people from the UK because the strain is  probably here already and it will be treated the same way as our original wild-type  strain.

In the foreseeable future we will learn more about this variant so stay tuned.

COVID 19 VACCINATION

INFORMATION

Be aware that information on COVID-19 and vaccines is changing daily. Your own GP can give you up to date advice on whether a vaccine is right for you based on your personal health circumstances. This information has been published on 07/12/2020 please ensure you are following our most up to date information. The purpose of this publication is for information only. The British Polio Fellowship disclaims all liability for any claims, losses, damages, costs and expenses incurred as a result of reliance on this information. It is not a substitute for advice from your doctor, physiotherapist or other health care professional

Pfizer vaccine roll out and polio

The trials to date have reported very few safety issues and no evidence to suggest that  people who have had polio or have PPS should not take the COVID 19 vaccine if offered.  Most people in the UK who had polio are over 65 and are at higher risk of serious illness  from COVID-19, so the clinical experts advising the BPF believe that they should have  the vaccine unless advised otherwise by their health care professional.

The NHS expect to offer the Pfizer vaccine first to people who live in care homes and  care home workers, to people over 80 yrs, and to health and social care workers.

Younger women should be aware that there is no safety data as yet for those who are  pregnant or breastfeeding or planning a pregnancy within three months of the first dose  and they are advised not to come forward for vaccination until at least 2 months after the  vaccine. If they have received the first dose inadvertently while pregnant, the 2nd dose  should be given after pregnancy.

Does having had polio or the polio vaccine give immunity?

You may have heard reports suggesting that having had polio gives immunity to COVID 19 – this is not backed by any clinical evidence.

You may have also heard reports that the polio vaccine gives immunity – again, this has  no clinical backing. (In fact, most people in the UK are given the polio vaccine , so if the  polio vaccine did give immunity – there would have been no COVID 19 epidemic in the  UK). What has been discussed is that receiving live vaccines might possibly give  protection against other diseases, but this has not been proven. The World Health  Organisation does not recommend the live oral polio vaccine (OPV) for the prevention of  COVID-19.

Will I be given priority because I had polio?

Polio/PPS is not specifically on the list of conditions that is considered to make people  clinically extremely vulnerable to COVID-19 and the BPF will continue to advocate for  this to happen. However, members may be offered the Pfizer virus sooner as they may  fall in the priority vaccine list , such as is they live in a care home or are over 80yrs.

Some people who had polio will have significant respiratory (breathing) problems or other  health conditions not related to polio which may make them clinically vulnerable or  clinically extremely vulnerable. For advice on your individual suitability for or benefit from  the vaccine, you should consult your GP or pharmacist ensuring they understand your  polio and other medical history. They will be able to take into account your personal  health risk and will have the latest information on the vaccine.

Do we still need to take precautions?

The government advice still is in place to take precautions around ‘Hands, Face, Space’.  Even after the vaccine is rolled out, it will take time for an immune response to build up  and for the NHS to determine how long the protection lasts. Everyone should continue to  practice due care and everyone must continue to follow whatever measures are in places  locally (such as the Tier system).

PHI Covid Vaccine

COVID-19 Vaccine  

Information for Polio  

Survivors

As the COVID-19 vaccines are approved for use and

begin to be given to Americans and others, PHI has

begun receiving questions from our constituents.

Remember our knowledge about the COVID-19 virus

is only about one year old and is continually being

updated which means information and

recommendations sometime change from month to

month. Your primary care physician, especially one

that has worked with you for some time, is the best source of information of what will be  recommended for YOU and your particular situation.

At this time, December 2020, here is how our Medical Advisory Committee is responding to these  questions:

Does having had polio or having received the polio vaccine give immunity to COVID 19? There has been a “theory” circulating that recent expose to some viral diseases or vaccines to  those viral diseases might “boost” the immune system and provide some protection against  COVID-19 but that is not backed by any clinical evidence. (If a history of receiving the polio  vaccine did provide protection against COVID-19, then the older people living in the developed  world, most of whom have been immunized against polio, would have a very low incidence of  novel coronavirus infections, and that is clearly not the case!)

Will I be given priority because I had polio? No, a history of polio does not in itself make a  person more likely to get COVID-19 or get sicker than others of similar age and other medical  conditions. So, a history of polio and/or PPS does not move an individual up the priority list. On the other hand, most people who contracted polio in the United States or Canada are over age 65 and  several even over 80 years old. Therefore, they are already in the “high risk” group, which  generally places them in the second tier of people slated to be offered the vaccine. Polio survivors  with respiratory compromise may rise up one level over others of a similar age group due to their  underlying respiratory condition; likewise for the polio survivor living in a nursing home or other  senior living situation. In the US, each state, with input from the national health authorities,  determined their own priority list, so where you fall in the priority tier system may vary slightly from  state to state.

After I get the vaccine, even the first dose, can I stop with all these “precautions”? We  don’t know all the particulars, but studies have shown less than 50% immunity two weeks after the  first dose which rises to greater than 90% protection two weeks after the second dose. Our  colleagues in the British Polio Fellowship summarize the precautions as “Hands, Face, Space,”  and the recommendation is to continue these precautions until enough people have received the  vaccine to minimize the risk of exposure from the general public.

Why do I need two doses? Because tests to date with the vaccines that are currently available  have shown only partial protection after the first dose and a much better immune response after  the second. This is not unusual for vaccines—to get full immunity from polio a minimum of three  (3) doses are recommended and four (4) are usually given; the shingles vaccine is a series of two

shots as are the measles, mumps, and rubella vaccine and the chickenpox vaccine. As new

COVID-19 vaccines are developed and approved it is possible that, at some point, we will have a  single dose COVID-19 vaccine that is safe and effective, but not yet.

Can I get COVID-19 from the vaccine? No, the technology used to make the COVID-19 vaccine  does NOT use any live virus or even part of the virus particle. All the new vaccines were made by  breaking and then artificially duplicating part of the genetic code contained in the spikes on the  surface of the COVID-19 virus. They work by blocking the virus from attaching to your cells and  then invading your cells and causing infection.

When all the vaccines become available which one(s) should I get? THE FIRST ONE THAT  BECOMES AVAILABLE TO YOU, REGARDLESS OF WHETHER ONE OR TWO DOSES!

Who should not get the vaccine? For now, it has not been adequately tested in youngsters  under the age of 16 years or in pregnant women, so it is recommended that the vaccine not be  given to those individuals until studies show the vaccines to be safe and effective in these groups.

There have been a few cases of severe allergic reactions in people with multiple significant  allergies to other substances, so, for now, persons with allergies severe enough to carry an Epi Pen should discuss with their physician before being immunized.

Late Effects of Polio a guide to management for medical professionals

Late effects of polio

A guide to management for medical professionals

ON YOUR TRUSTED TEAM FOR LIFEBackground

The World Health Organisation estimates there are 20 million people worldwide currently

living with some degree of disability caused by poliomyelitis (1). Not all polio survivors were

diagnosed with paralytic polio. However, 99% of all polio survivors may have experienced

sub-clinical damage that becomes more evident with age.

The late effects of polio is a neuromuscular condition that can occur in a high percentage

of people with prior exposure to polio. In Australia, it is estimated there are tens of thousands

of polio survivors. International surveys indicate there is up to 80% prevalence of late effects

of polio in polio survivors.

As late polio symptoms progressively worsen, patient coping mechanisms used for many

years may no longer be effective. Over time, partners and carers of polio survivors may

find themselves providing more assistance to the polio survivor. As the progression may

be gradual, the polio survivor and carers may not initially understand or appreciate the

magnitude of the impact of the late effects of polio on their lives.

Impact of polio

In the acute disease, the polio virus attacks the motor neurons resulting in varying degrees

of muscle paralysis and weakness. The brainstem is also involved in the initial infection,

particularly the reticular formation, vestibular nuclei, cerebella nuclei, hypothalamus and

thalamus, and the cranial nerves. Recovery involves the reinnervation of orphaned muscle

fibres by nearby neurons, resulting in enlarged motor units and muscle fibre hypertrophy.

Muscles that appear unaffected can have significant subclinical denervation, the effects

of which usually emerge as the polio survivor ages. Beyond the acute phase there is a period

of stable non-progressive level of disability for several decades.

Impact of the late effects of polio

Pathology: The leading causal hypothesis is that excessive metabolic stress on the remaining

motor neurons, possibly due to long term muscle overuse, results in distal degeneration

of terminal axons and eventually loss of motor neurons. The rate of loss is about twice that

of normal aging. After polio ongoing denervation and reinnervation occurs, but with time the

ability to reinnervate orphaned fibres diminishes. This can occur many years later in muscles

that appear normal but have subclinical denervation.

Treatment: There are no medications currently available to prevent or reverse muscular

atrophy, improve neuromuscular strength or relieve the neuromuscular fatigue of late effects

of polio.

The late effects of polio:

a gradual or sudden onset of progressive and persistent new muscle weakness or

abnormal muscle fatigability (decreased endurance), with or without generalised

fatigue, muscle atrophy, or muscle and joint pain. Sudden onset may follow a period

of inactivity, trauma, or surgery. Less commonly, symptoms attributed to late effects

of polio include new problems with swallowing or breathing.Presentation

Polio survivors may present with new weaknesses, pain, neuromuscular and/or general

fatigue, respiratory difficulties, or sleeplessness. Although affected patients may refer to their

prior episode of polio, many do not willingly disclose past exposure due to past significant

stigma they may have experienced due to polio infection.

As early symptoms of the late effects of polio, such as fatigue, are commonly experienced

by the general population, polio survivors may live with significant and worsening problems

for a considerable time before seeking medical help.

New symptoms may also reawaken the emotional distress experienced during the initial

disease, making discussion difficult for patients. This emotional distress may extend

to traumatic experiences in hospitals and health care facilities, and a general wariness

or mistrust of medical advice.

Diagnosis

The diagnosis of late effects of polio relies nearly entirely on clinical information. There are

no laboratory tests specific for this condition and symptoms vary greatly among individuals.

An extensive work-up including laboratory tests, imaging studies, cerebrospinal fluid

sampling, detailed electrophysiological evaluation, and muscle biopsies may be required

to exclude alternative diagnoses. The diagnostic criteria for Post-Polio Syndrome was first

proposed by Halstead in 1991 (3) and evolved over time to the current March of Dimes

diagnostic criteria (4, 5) which include:

  1. Prior paralytic poliomyelitis with evidence of motor neuron loss, as confirmed

by history of the acute paralytic illness, signs of residual weakness and muscle atrophy

on examination, or signs of denervation on EMG.

  1. A period of partial or complete functional recovery after acute paralytic poliomyelitis,

followed by an interval (usually 15 years or more) of stable neuromuscular function.

  1. Gradual onset (rarely abrupt) progressive and persistent new muscle weakness or

abnormal muscle fatigability (decreased endurance), with or without generalised fatigue,

muscle atrophy, or muscle and joint pain. Onset may at times

follow trauma, surgery, or a period of inactivity. Less

commonly, bulbar dysfunction or respiratory weakness occurs.

  1. Symptoms that persist for at least a year.
  2. Exclusion of alternative neuromuscular, medical, and orthopaedic problems as causes

of symptoms.

Suggested recommendations for GPs include:

› Including a ‘tick box’ on the new patient registration form for your practice

promoting patients about their polio history

› Conduct an annual health check to review mobility, swallowing and respiratory

problems of polio survivors

› Check current psychological status of polio survivors.Diagnostic considerations:

  1. Anaemia
  2. Chronic infection
  3. Collagen disorders
  4. Deconditioning
  5. Depression
  6. Hypothyroidism
  7. Infectious myopathy
  8. Myasthenia gravis
  9. Deconditioning and weakness

› Age at best recovery

› Maximum functional recovery

History since polio › Change in functional ability, degree,

speed and nature of change

Present status › Recent changes in activity levels,

employment, environment, nutritional

status, general health and lifestyle

Assessment

Effective assessment requires a full history and review of symptoms, including:

› Early experiences of polio. Explore the physical and psychological impact on their lives.

Identify areas affected in the original polio episode and extent of recovery. Document

any residual long-term effects of initial polio episodes, individuals who have very severe

residual weakness, individuals who had early bulbar respiratory difficulty in the acute

illness, and persons who were older when they contracted acute polio. Late polio

symptoms also tend to occur first in weaker muscles.

› Natural history of presentation. Document and differentiate symptoms of late polio,

including their pattern and progression.Pattern and impact of physical activity

Chronic overuse of affected or unaffected muscles can trigger or exacerbate symptoms.

Health professionals need to make enquiries into activity levels in paid or unpaid work,

sports/fitness training or daily living.

Enquiries need to include any changes to levels or intensity of physical activity.

Fatigue, weakness and pain. Exclude other possible causes of fatigue. The presentation

of fatigue in a polio survivor patient may resemble other conditions and risk potential

misdiagnosis.

Commonly used assessment tools such as manual muscle testing can give a false impression

of strength as one-off movements may be strong. However, polio survivors often show poor

endurance over repeated movements or during sustained activity.

Respiratory insufficiency may develop insidiously, initially at night, in individuals who

appeared previously unaffected, although respiratory disorders are most prevalent in

patients with residual muscle weakness. Symptoms may include unrefreshing sleep, frequent

wakening, waking with headaches, daytime sleepiness, waking gasping or difficulties lying

flat. Obstructive sleep apnoea is also common in polio survivors.

These complications are most prevalent when there is an additional strain on the respiratory

muscles such as respiratory infections, periods of immobility, surgery or obesity. Assessment

for respiratory complications should be considered both for those with night-time symptoms

or daytime effort-related shortness of breath.

Difficulty with swallowing is a potentially serious problem for people living with late effects

of polio. Common symptoms include increased swallowing time and food catching in the

throat. Weakness in pharyngeal constrictor muscles are common in late polio, even in the

absence of symptoms. Patients should also be assessed for risk of aspiration pneumonia.

If swallowing difficulties are suspected, referral to a speech therapist is strongly

recommended. The referral should advise that any tests involving observing muscle action

need to involve several repetitions to assess the impact

of abnormal neuromuscular fatigue.

Cold intolerance is common but underreported

and can affect motor function and comfort.

Walking and postural disturbances.

Difficulty in walking can be due to progressive

weaknesses and joint instability. Walking

problems are more common in people

who have used mobility assistance devices

in the past and have discarded them.

Postural problems can be related

to spinal malformations and weaknesses

in truncal muscles.Recommended management interventions

A multidisciplinary approach:  The ideal approach involves coordinated

multidisciplinary treatment often involving rehabilitation specialist doctors, GPs,

physiotherapists, occupational therapists, orthotists, other medical specialists and allied

health professionals as required (see referral criteria).

Energy management techniques: Successful energy management techniques, best taught

through referral to a specialist physiotherapist or occupational therapist, can help alleviate

the symptoms of neuromuscular and general fatigue and reduce pain. Techniques include:

› Pacing activity  Effective in reducing neuromuscular fatigue and pain and may

improve performance for some.

› Energy conservation  Adapting, simplifying and prioritising daily tasks can

preserve energy and avoid neuromuscular fatigue and pain.

› Aids and appliances  These can help in energy management. Late effects

of polio patients may need encouragement to use aids, which may remind them

of the original polio.

Orthotics:  An orthotics review by an experienced specialist can help reduce overuse

and misuse and reduce energy cost of walking by optimising orthoses and footwear.

Optimised orthotics may help reduce falls.

Respiratory management:  For respiratory insufficiency, confirmed by a respiratory

specialist, due to weak respiratory muscles or scoliosis, respiratory support in the form of

non-invasive ventilation, normally bilevel positive pressure (BiPAP), usually only at night,

is the recommended treatment. Continuous positive airway pressure (CPAP) is used for

obstructive sleep apnoea. If secretion retention is an issue, a respiratory physiotherapist can

advise on positions of treatment and devices such as cough assist that might be useful in the

case of a persistently weak cough.

Exercise and physical activity:  Once good energy management is established, these

can be considered under the guidance of a specialist physiotherapist with experience in

management of neurological conditions, to strengthen muscles where possible and help

improve cardiovascular health.

Caution: safe effective exercise for people with late effects of polio requires an individually

tailored non-fatiguing, pain-free program and careful monitoring to avoid overuse.

Pharmacological management:  As there is no medication proven to reverse the progress

of late effects of polio, pharmaceutical interventions are aimed at alleviating symptoms such

as fatigue, pain and poor sleep. To date, none have been proven to reduce the fatigue and

neurological weakness of late effects of polio. Some medications can alleviate pain and are

used after energy management techniques have been tried.

Psychological therapies:  May be helpful in treating symptoms such as depression

and anxiety. They may also enhance the efficacy of physical interventions by promoting

behaviour change and improving the ability to cope with physical symptoms.

The strength of the evidence is indicated:

 very strong.  strong.  for some.  may help, caution advised!Side effects of some medications can worsen symptoms of late effects of polio including

increased weakness, fatigue, respiratory depression or muscle pain/cramps:

› Anabolic steroids: Steroids are not recommended to improve muscle bulk as the risks

due to side effects greatly outweigh the potential benefits. Metabolic stimulants such

as L-Carnitine and Coenzyme Q10 have been studied and used in some parts of Australia

but have not been proven to be effective.

› Intravenous immunoglobulin: The efficacy and safety of intravenous immunoglobulin

is currently the subject of a multi-centre randomised controlled trial.

› Statins: Many polio survivors have read that some medication classes are bad for

them, including statins. While some statins may lead to muscle fatigue and pain, health

professionals are best placed to provide advice to patients with late effects of polio and

to monitor any potential side effects of statins.

› Anaesthetics: Anaesthetics can cause gastro-oesophageal reflux, tachyarrhythmia and,

sometimes, difficulty maintaining blood pressure.

› Sedatives: Patients with the late effects of polio are nearly always very sensitive to

sedative medications, and emergence can be prolonged. This is probably due to central

neuronal changes, especially in the Reticular Activating System, from the original disease.

› Analgesics: People with late effects of polio may experience breathing problems.

As opioid based analgesics can depress breathing, precaution should be taken when

prescribing them in a patient with the late effects of polio.

› Vaccination: Pneumococcal and influenza vaccinations are recommended.

Nutrition and weight management:  Dietary advice to optimise nutritional status may

also support functional status of the person with the late effects of polio. Weight loss may

help reduce neuromuscular fatigue and pain, taking account of probable low proportion of

lean mass and low mobility. A person being underweight may be due to poor diet, swallowing

issues or difficulty shopping/cooking and may impact late effects of polio symptoms.

Caution: if advising exercise, ensure you recommend a safe and effective program.

Other conditions: Management also needs to include treatment of other conditions which

occur more commonly in polio survivors such as osteoporosis and peripheral neuropathies.

Smoking cessation advice and support may help prevent worsening respiratory function

and vascular complications in a person with the late effects of polio.

Regular monitoring: As the polio survivor with features of the late effects of poliomyelitis

will potentially decline functionally with time, regular annual review helps identify changing

and progressive symptoms and early opportunities to intervene and adapt the individual’s

management program accordingly.

Criteria for referral to secondary care

› Development of new neurological symptoms

› Progression or deterioration of longstanding neurological symptoms

› Uncertainty regarding the diagnosis of late effects of polio

› Advice about symptom management of late effects of polio, especially where respiratory

complications or dysphagia are suspected

› Need for advice on failure of treatment that was previously effective in late effects of polio

› Need for specialist advice on orthotics, biomechanics and orthopaedic problems.1300 774 625

Common Misconceptions PPS

Common Misconceptions Concerning the Post-Polio Syndrome

Peter Brauer MD

“Someone once said that everyone has the right to their own opinion but not to those based on their own facts.” John Robbins

Currently, over 99% of physicians do not possess the knowledge required to treat polio survivors for a polio encephalic-myelitis and the Post-polio syndrome (PPS). The general level of knowledge ranges from strongly  predominant ignorance to superficial perceptions and half-truths masked with misjudgement, even though the  poliomyelitis disease, also known as infantile paralysis, is one of the best studied infections in the world. Due to  professional ignorance, the state of recognition and the state of knowledge differ catastrophically. This is clearly at the  expense of the affected patients, most of whom are misdiagnosed and subsequently wrongly treated.

For PPS patients, a misdiagnosis rate of more than 99 percent must be assumed, including asymptomatic and  abortive infection courses with their sequelae. Even under the exclusive consideration of paralytic illness cases, the  polio survivors still have approximately the same magnitude of misdiagnosis.

With a few exceptions, the condition PPS exceeds the imagination of those who are not affected to a point of complete  incomprehension. This lack of understanding ranges from family members, friends, acquaintances, work colleagues,  doctors, health insurance companies, medical services, physiotherapists, health and social services, expert  ascertainment services, right up to the social courts. The patient affected has to explain countlessly everywhere,  whereby encountering unbelief and ignorance and is accused of being a know-all if he is a disease related informed  patient and also not infrequently discredited even to the extent of being regarded as psychosomatic, depressive or even as a simulant.

Just a few errors or opinions offered as facts repeatedly in everyday practice prevent an adequate PPS diagnosis.  These are referred to below:

* Poliomyelitis is a disease of the anterior horns of the spinal cord

This statement consists of several half-truths.

  1. Poliomyelitis is not just an illness, but already disease-worthy as an infection, since as such, it leaves permanent damage to the central nervous system (CNS), under which the spinal cord and brain are to be understood. 2. On infection, the spinal cord is mostly affected. The brain on the contrary is always affected. So it is strictly speaking, a polio-encephalic-myelitis disease.
  2. Infection and illness lead to damage in the CNS. It usually occurs in the spinal cord, but always causes consequential damage to the brain. Strictly speaking, the brain is “preferentially” infested, which means that during the incubation phase it is reached the fastest through the blood stream by the most massive of the polio viruses. 4. Not only the anterior horns of the spinal cord, but also the side horns and hind horns, as well as the dorsal root  ganglia, may be affected.

* Poliomyelitis is a disease of the alpha motor neuron

This statement is imperfect.

  1. It is strictly speaking a polio-encephalic-myelitis (see above)
  2. Not only alpha motor neurons, but nerve cells, which innervate the muscular fibres of voluntary movement and nearly all neuro-regulatory brain areas such as brain activation, motor skills, pain regulation, the temperature regulation, respiratory regulation, stress regulation, sensitivity, cardiac circulatory regulation, hormone regulation and  emotion regulation, can be affected.

* The bulbpontine and the encephalitic form of polio infection are extreme rare

This statement is incorrect in its incompleteness.

All polio infections are encephalitic and can damage the whole brain, mostly functional depending on the functional  load for a more or less long period, as a result of the ability of the brain to compensate (equalization = neurogenic  plasticity), which remains hidden (subclinical) to the outside. About 5 – 10% of course forms with visible (clinical)  symptoms show involvement of the central nervous system (CNS). Thus, according to general understanding, the  abortive, the aparalytic and paralytic forms are meant, of which the paralytic form in about 1% of cases of infection can

1

be found. With regard to the Post-polio syndrome, the subclinical bulbopontine and encephalitic infectious history are  virtually always given, only the clinical proportion is relatively rare.

* The polio disease follows a stable phase after recovery

This statement is imperfect.

It is not a real stable phase, but a clinically stable phase with a subclinical unstable background. The losses of  destroyed nerve cells are compensated through previously damaged and / or healthy nerve cells. The functional and  structural compensation process is subject to constant reconstruction and decomposition with a limited durational  magnitude. This is only clinically visible after a loss of about 50% of the nerve cells in a functional area due to  functional impairment or functional failure. Even before this limit is exceeded, a subclinical PPS degenerative process  may exist, which always emanates from the brain.

* The stable phase lasts at least 10, 15 or even 20 years

This statement is incorrect.

PPS is a degenerative disease of the overburdened balancing nerve cells of the brain and spinal cord. Transient  processes in the musculature are also affected. The period up to their overload failure depends on the magnitude of  the previous damage and the duration and extent of the relative or absolute load / overload. This can last from a few  years, rarely months, up to several decades, without an upper time limit.

* A polio illness must be known for a PPS diagnosis

This statement is incorrect.

98% of polio infections go unnoticed without disease or are uncharacteristic but also carry a PPS risk. On clinically  and / or epidemiologically probable infections on diagnosis, is also at least a possible post viral late effect to be taken  into consideration.

* A PPS after an aparalytic polio is not credibly proven

This statement is incorrect.

A PPS can be expected with the aparalytic, the abortive and the inapparent (asymptomatic) infection course. A  credible verification being the same as a proof of claim does not exist for the paralytic course of infection. Clinical and  para-clinical findings are generally unspecific with PPS, or otherwise even mainly inconspicuous. Decisive is a  compulsory thorough medical case history. This applies for all infection courses of polio-encephalic-myelitis. Polio related damage to the central nervous system (CNS) is proven in all infections of the asymptomatic, the abortive, aparalytic and paralytic courses. In any case, this results with the risk of a later PPS.

* For a PPS diagnosis disease consequences must be apparent

This statement is incorrect.

Visible sequelae such as muscle paralysis and muscle atrophy need not exist. 99% of polio infections occur without  paralysis and their consequences such as muscular dystrophy, however not without a PPS risk. Also, paralysis may  have regressed in the recovery phase after the disease.

* A preserved sensitivity is required for a PPS diagnosis

This statement is incorrect.

During the polio infection, areas of sensitivity such as in the dorsal root ganglia or in the brain can also be damaged  and later lead to PPS symptoms.

* At least two or more characteristic symptoms must exist for a PPS diagnosis

This statement is incorrect.

The requirement for at least two or more existing symptoms is par excellence medical nonsense. Any indicative  symptom of over 100 possibilities may or may not be required to exist. The virus infestation of nerve cells is irregular  in location and extent, therefore also the late effects. In addition, weak symptoms are often not perceived or not  registered as disease worthy. One mostly initially unique indicative symptom is sufficient for the suspected diagnosis.

Proofing symptoms do not exist. All possible indicative symptoms may be single or in different combinational  occurrence. They may or may not be constantly present. Their occurrence can be timely, vary locally and in strength.

* The symptoms must have persisted for at least 1 year for a PPS diagnosis

This statement is incorrect.

The PPS usually begins insidiously creeping, but can also be suddenly noticeable. A diagnosis is obligatory on its  beginning. The probability of a different causative disease with the same symptoms or additionally causative disease  is always possible. However, the PPS diagnosis never excludes parallel diseases as indicative symptoms.  Consequently, the diagnosis PPS is not limited in time tied to a minimum duration of its symptoms. It is also  mandatory with changing symptoms.

* Other diseases must be excluded for a PPS diagnosis

This statement is incorrect.

The exclusion of other diseases serves to prevent their treatment not to be missed out and not just purely a PPS  confirmation. Their presence does not exclude the PPS, because an exclusion diagnosis cannot be excludable as  such. Parallel diseases are possible. In the presence of corresponding symptoms, the PPS diagnosis has to be kept  independent from other illnesses. The suspected diagnosis thus remains.

* A new increasing muscle weakness must be present for a PPS diagnosis

This statement is incorrect.

Although new muscle weaknesses are common, they are not a condition for a PPS diagnosis. Predominantly the first,  most frequent and main symptoms are states of fatigue, which often register very late as disease-grade with slow  onset and progression. In addition to exhaustion, for example, pain, as an indicative symptom, occurs without  evidence of apparent muscle weakness.

* Clinically ill conditions with polio survivors should not automatically suggest a PPS This statement is misleading.

Without exception and in addition to other illnesses with polio survivors, PPS should always be considered  automatically.

* The causes of the PPS are still unknown

This statement is incorrect.

PPS is the result of a chronic relative as well as absolute overload, caused by a polio infection with or without disease  of previously damaged and diminished healthy nerve cells, which depending on the strength and duration and result of  overloading, after a more or less long period of time, die-off. It is therefore as in sports medicine defined described as  an overtraining syndrome. Only the molecular sequence of event processes are not yet known, which do not matter  for the diagnosis and the required symptomatic treatment

* The Post-polio syndrome is very rare

This statement is incorrect.

When only 1% to 1%o of polio infections have a paralysis, but all the infection courses have the risk of a later PPS, the  reported cases of paralysis are multiplied by 100 to 1,000 to reach the approximate real number of polio-infected.  According to the official risk profile gained from the proportion of the population, this results in the fact that there are  actually always more PPS patients as defined under the definition for rare disease. A rare disease is considered to be  less than 1 patient in 2,000 inhabitants.

* Post-polio syndrome is not a disease

This statement is incorrect.

The term syndrome is used to describe “… the simultaneous presence of various symptoms, so called symptoms” (Wikipedia) with known cause and unknown development. Only with known cause and known development is the term

3

syndrome usually avoided and generally described as clinical picture. In that sense, it is an unfortunate choice of the  consensus to call the polio late effects term a Post-polio syndrome, as this is a disease where cause and development  – with the exception of molecular biology processes – are known. On the other hand, this term refers to the characteristic variety of possible symptoms and the complexity of the disease, which is quite an advantage for primary  diagnostic understanding. This is also followed by the WHO in their classification of diseases ICD 10 with the code G  14 Post-polio syndrome as a name for an independent disease.

* Post-polio syndrome is an immunological disorder

This statement is incorrect.

With PPS, nerve cells die-off as a result of chronic overload. The cellular decomposition process leads to the release  of cell components, some of which are protein molecules that activate the immune system. This has a local inflammatory reaction resulting in the framework of cell debris removal. In some cases, it can also release poliovirus  fragments from cell-inactivated and fragmented polio viruses, which lead to this nonspecific reaction. Freed virus  genetic material (RNA) in the form of fragments can therefore also directly trigger an immune response. This is secondary non-causative to the PPS immune process. Immunological inflammatory processes can also be primarily  triggered through chronic stress without structural degenerative processes. Chronic stress is one of the main causes  of the Post-polio syndrome. The brain is also affected by this process.

Conclusion

As long as the polio-encephalic-myelitis is considered just to be polio-myelitis with almost exclusive limitation to the  consequences of the body motor system in the form of pitiable paralysis and skeletal deformities, whereby other  consequences of the infection to the spinal cord and especially to the brain, are not considered, then the late effects,  the Post-polio syndrome cannot be understood and thus not properly diagnosed and treated. As long as clinical proof  and para-clinical symptoms or finding requirements for a diagnosis are continuously being sought, where in any  exclusion diagnosis, as even in this case only naturally indicative, which do not exclude such a disease and parallel diseases from the outset, misdiagnosis and mistreatment are inevitable. The basis for the detection of a Post-polio syndrome is the medical case history. No diagnosis in the case of  a suspected Post-polio syndrome is already a misdiagnosis!
