Update on current and emerging treatment options for post-polio syndrome

Joint and Back Pain: Medications and Role of Injection Therapy for Destructive Joint

Postpolio syndrome (PPS) is a sequela with symptoms that often occur in patients who previously survived poliomyelitis. Pain is a characteristic feature of PPS. Although poliomyelitis is no longer commonly seen in the western world, there is a significant portion of patients living with PPS. Recognizing the signs of PPS is integral in developing treatment plans. Conservative management is routinely considered first-line therapy; however, alternate treatments, pharmacologic and minimally invasive, are used in more refractory cases. Approaching patients living with pain and PPS requires a holistic approach and an understanding of the efficacy of available treatment modalities.

Approach to Fatigue and Energy Conservation

Fatigue, a common complaint in individuals with postpolio syndrome (PPS), is defined as an overwhelming sustained feeling of exhaustion and diminished capacity for physical and mental work. A comprehensive medical work-up is needed to rule out all other causes of fatigue. A sleep study should be considered for individuals with PPS who complain of fatigue. Self-reported outcome measures, such as the Fatigue Severity Scale, are reliable and valid tools to measure fatigue in this population. Fatigue management consists of individualized treatment of underlying medical conditions, energy conservation, pacing techniques, and lifestyle modifications.

Reducing the Effect of Functional Disability on Life Satisfaction Among Persons With a Lived Experience of an Infectious Viral Disease in Taiwan: A Tri-Mediation Model

The purpose of the study was to examine whether disability acceptance, hope, and resilience mediate the relationship between functional disability and life satisfaction in people with a lived experience of an infectious viral disease (i.e., polio and postpolio syndrome [PPS]). Participants consisted of 157 individuals diagnosed with polio or PPS who were recruited from two community support organizations in Taiwan. Participants completed self-report questionnaires. Data were analyzed with a simultaneous regression analysis. The tri-mediation model indicated that disability acceptance, hope, and resilience were associated with life satisfaction, accounting for a large effect size of 46% of the variance in the life satisfaction scores. The direct effect of functional disability on life satisfaction became insignificant when the mediators were controlled for in the model. Hope, disability acceptance, and resilience were found to fully explain the association between functional disability and life satisfaction. This study demonstrated that positive psychosocial factors might help to buffer the indirect and direct negative effects of functional disability on life satisfaction. Implications of these findings for future research and clinical practice when supporting individuals with a lived experience of an infectious viral disease, including COVID-19, are discussed.

Primary breast cancer patient with poliomyelitis: A case report

BACKGROUND

Poliomyelitis is an acute infection caused by an enterovirus, which primarily infects the human gastrointestinal tract. In general, patients with polio have no association with the occurrence of cancer. The present case study presents a rare case of poliomyelitis combined with primary breast cancer.

CASE SUMMARY

A 61-year-old woman who was diagnosed with poliomyelitis at 5 years old and confirmed invasive breast cancer by core needle biopsy (CNB) after hospitalization. The patient received a modified radical mastectomy and four cycles of chemotherapy with the TC (docetaxel and cyclophosphamide) regimen. The patient was also prescribed endocrine therapy without radiotherapy after chemotherapy. The patient had no evidence of lymphedema in the right upper extremities and no evidence of either regression or distant metastasis at the 1-year follow-up.

CONCLUSION

The pectoral muscles of patients with polio are easily damaged in traumatic procedures, such as CNB, local anesthesia for tumor excision, and general anesthesia for surgery. A CNB, modified radical mastectomy, and four cycles of TC chemotherapy were successfully completed for the present case and the adverse reactions were found to be tolerable. This case may indicate the relationship between breast cancer and polio, and the examination and treatment methods used could be used as a guide for similar cases in the future.

Physical activity and quality of life predictors among university students with polio in India: A cross-sectional study

BACKGROUND

Quality of life (QoL) assessments measure the overall well-being of a person. Available data suggest an estimated 10-20 million polio survivors worldwide. Few studies have investigated the physical activity and the QoL of these patients in India.

AIM

The present cross-sectional study attempted to measure the physical activity and QoL of polio survivors and to evaluate the relationship between physical activity and QoL, among other factors.

METHODS

The study was conducted in 96 students (64 women and 32 men with a mean age of 22.1±3.7 years). QoL, physical activity, fatigue, and pain were measured by the World Health Organization QoL measure - abbreviated version (WHOQOL-BREF), physical activity scale for individuals with physical disabilities (PASIPD), multidimensional fatigue symptom inventory-short form (MFSI-SF), and numerical rating scale.

RESULTS

The mean metabolic equivalent score was 27.10 h/day. Low mean scores were observed for the physical health, psychological well-being, social relationships, and environmental domains of QoL (25.2±3.3, 21.8±3.0, 12.0±1.8, and 23.0±4.3, respectively). There was a weak negative association between physical activity levels and the physical health domain of QoL (P<0.05), whereas no associations were identified between physical activity levels and other QoL domains (P>0.05). Regression analysis identified female gender, fatigue, and physical activity as predictors of the physical health domain, and female gender, number of sites affected, and assistive devices used as predictors of the psychological health domain of QoL.

CONCLUSIONS

Low physical activity levels and QoL were noted among students with poliomyelitis in Uttar Pradesh, India.

RELEVANCE FOR PATIENTS

Considering the inverse relationship between physical activity and QoL, physical activities should be modified or protected in polio survivors. Female polio survivors may be referred to psychological counseling to learn coping strategies, even during periods of relative stability.

Postpolio Syndrome: A Review of Lived Experiences of Patients

Postpolio syndrome (PPS) refers to a group of conditions that are present in patients, years after recovery from initial acute paralytic poliomyelitis. About 15%-80% of 20 million polio survivors worldwide will experience exacerbation of symptoms which typically appear 15-30 years after the resolution of initial poliomyelitis. Symptoms include new muscle weakness, fatigue, myalgia, joint pain, dysphagia, and difficulty breathing. Other reported symptoms include cold intolerance, sleep disorder, dysphonia, loss of stamina, musculoskeletal deformities, cardiovascular disorders, psychosocial problems, and restless legs syndrome. These symptoms are attributed to the superimposed neuronal loss of aging with inflammatory mechanisms, but without any convincing evidence of viral reactivation. Risk factors include female gender, respiratory symptoms, normal aging, permanent disability caused by motor neuron damage, muscle overuse and disuse, aging, and immunologic mechanisms. Hypothyroidism-induced myopathy and fibromyalgia are a differential diagnosis for PPS, and exclusion diagnosis is required as confirmatory criteria for PPS. The symptoms of PPS presented determine the course of management.

Post-polio Syndrome: More Than Just a Lower Motor Neuron Disease

Post-polio syndrome (PPS) is a neurological condition that affects polio survivors decades after their initial infection. Despite its high prevalence, the etiology of PPS remains elusive, mechanisms of progression are poorly understood, and the condition is notoriously under-researched. While motor dysfunction is a hallmark feature of the condition, generalized fatigue, sleep disturbance, decreased endurance, neuropsychological deficits, sensory symptoms, and chronic pain are also often reported and have considerable quality of life implications in PPS. The non-motor aspects of PPS are particularly challenging to evaluate, quantify, and treat. Generalized fatigue is one of the most distressing symptoms of PPS and is likely to be multifactorial due to weight-gain, respiratory compromise, poor sleep, and polypharmacy. No validated diagnostic, monitoring, or prognostic markers have been developed in PPS to date and the mainstay of therapy centers on symptomatic relief and individualized rehabilitation strategies such as energy conservation and muscle strengthening exercise regimes. Despite a number of large clinical trials in PPS, no effective disease-modifying pharmacological treatments are currently available.

Pitting oedema in a polio survivor with lumbar radiculopathy complicated disc herniation

We report a 58-year-old male with sequelae of polio who presented with low back and left buttock pain, and pitting oedema of both legs for four months. The patient had a history of poliomyelitis at the age of 1 year which resulted in bilateral lower leg weakness, particularly on the left side. Magnetic resonance imaging showed cervical spinal stenosis secondary to posterior osteophyte formation, left paracentral disc extrusion at L2/L3 and L3/L4 levels with compression of the traversing L4 nerve root. The findings confirmed a diagnosis of lumbar radiculopathy caused by a herniated disc. The patient subsequently underwent a chiropractic treatment. The painful symptoms and pitting oedema in this case resolved with spinal adjustment in addition to scraping therapy to strengthen bilateral low back and the gluteal muscles. This case provides circumstantial evidence of a scarcely mentioned association between pitting oedema and lumbar radiculopathy caused by disc herniation. The pathophysiological mechanism is elusive, but might involve a complexity of cytokine-mediated inflammation and interconnection between somatic and autonomic nervous systems.

Self-perceived mobility in immigrants in Sweden living with the late effects of polio

Purpose: To investigate outdoor mobility of immigrants in Sweden who are living with the late effects of polio.Materials and methods: A total of 145 patients with late effects of polio born outside the Nordic region were identified at an outpatient polio clinic. Of these, 74 completed a questionnaire about their mobility and independence in daily life, self-perceived pain and depression, vocational status, mobility assistive devices/aids, transportation modes and driving. Patient characteristics were based on medical records supplied by physicians.Results: Twice as many patients had lower extremities that were affected by polio than upper extremities. This affected their use of different transport modes and caused mobility and transfer problems. Indeed, 39% needed mobility aids and help from another person to move outdoors. Those who reported dependence for outdoor mobility were more often unemployed and more often depressed.Conclusions: Many respondents reported having difficulties with transport mobility, but a large proportion, 57%, were independent and active drivers. It is important to consider outdoor mobility when planning rehabilitation for patients with late effects of polio and foreign backgrounds. In addition to psychosocial factors, dependence on mobility-related activities can lead to dependency and isolation.Implications for rehabilitationOutdoor mobility and access to transport modes are important for independence and an active life and need to be included in the rehabilitation process.Both personal and environmental factors, can contribute to mobility problems of people with foreign backgrounds, who are living with the late effects of polio.Factors such as cultural, social and gender aspects are important when planning suitable and individualized rehabilitation.

Poliomyelitis

Poliomyelitis, often termed "polio," is an acute infectious disease caused by an enterovirus which damages the anterior horn cells of the spinal cord and brainstem. Progress to lower motor neurone cell death leads to disruption of motor units and subsequent muscle weakness or complete paralysis. Although the virus is mostly eradicated from the Western world, postpolio decline is prevalent among people aged 60 years and over. It is characterized primarily by fatigability and muscle weakness, but pain is also common. Reductions in lower-limb muscle strength, voluntary drive, and endurance are likely to contribute to the impaired balance control, slow gait, and dysfunctional lower-limb kinematics reported in polio survivors. Given these significant risk factors, polio survivors fall up to four times more often than their age-matched healthy peers. Interventions to improve function, reduce disability, and prevent falls in polio survivors are therefore clinically relevant but studies are lacking, limiting the evidence base. Balance training, cognitive behavioral therapy, and orthoses prescription might be recommended. Muscle-strengthening programs should be carefully designed and delivered due to their potential detrimental effects related to excessive use and potential dysfunction of motor neurones and their axons.

Polio survivors perceptions of a multi-disciplinary rehabilitation programme

PURPOSE

Post-polio syndrome refers to a late complication of the poliovirus infection. Management of post-polio syndrome is complex due to the extensive symptomology. European and United Kingdom guidelines have advised the use of rehabilitation programmes to manage post-polio syndrome. There is a paucity of research in relation to the effectiveness of rehabilitation interventions. The objective of this study is to explore polio survivor's perceptions of an in-patient multi-disciplinary rehabilitation programme.

METHODS

Semi-structured interviews of community dwelling polio survivors who attended in-patient rehabilitation programme in the United Kingdom. Thematic analysis was used to describe and interpret interview data.

RESULTS

Participants' experiences were influenced by past experiences of polio and their self-concept. Participants generally had a positive experience and valued being with other polio survivors. Positive strategies, such as pacing and reflection changed their mind-sets into their lives after the programme, though they still faced challenges in daily living. Some participants supported others with post-polio syndrome after completing the programme.

CONCLUSIONS

Our research identified that participants experienced long term positive benefits from attending a rehabilitation programme. Strategies that users found helpful that explored the effectiveness of interventions to manage polio are not cited within a Cochrane review. If we are to recognise the lived experience and service user empowerment within a model of co- production it is essential that patient preferences are evaluated and used as evidence to justify service provision. Further research is required with polio survivors to explore how best rehabilitation programmes can adopt the principles of co-production. Implications for Rehabilitation The patients' expertise and lived experience must be at the centre of a rehabilitation programme. Strategies such as pacing and reflection are perceived as important strategies to enable self-management of polio and post-polio syndrome despite the limited evidence base to support these interventions. Polio rehabilitation programmes should not be time limited and commissioners and therapists need to ensure that follow up support is provided. When measuring outcomes patient preferences and views must be evaluated.

Post-polio syndrome. Cases report and review of literature

It is estimated that around 15 million people survived polio infection worldwide since early twentieth century. In 1950 effective vaccination was used for first time. Since that time number of affected people decreased. The last epidemic of Haine-Medine disease in Poland was in 1950s. Another rare cases of infections were observed till 1970s. About at least 15 years after polio virus infection, slowly progressive muscle limbs paresis with muscle atrophy, joints pain, paresthesia were observed in polio survivors. That constellation of symptoms was called post-polio syndrome (PPS). PPS frequency among people after paralytic and nonparalytic polio infectious is ranged from 30% to 80%. Fatigue that leads to physical and mental activity deterioration is another important symptom that is observed in 90% of patients with PPS. Etiology of disease remains elusive. Probably it is an effect of spine frontal horns motoneurons damage during acute virus polio infection that leads to overloading and degeneration of remaining ones. The most important risk factors of PPS are female sex and respiratory symptoms during acute polio infection. Electromyography is an important part of PPS diagnostic process. Electrophysiological abnormalities are seen in clinically affected and unaffected muscles. The most frequent are fasciculations and fibrillations during rest activity, extension of motor unit area, time duration and amplitude. In this study we described three cases of people who developed PPS years after Haine-Medine disease and correlation between their EMG results and clinical status. We also analyzed electromyography results both after one month since first PPS signs occurred as well as after few years. Presentation of dynamic changes in EMG was the most important aim of that study.

Evaluation of gait symmetry in poliomyelitis subjects: Comparison of a conventional knee-ankle-foot orthosis and a new powered knee-ankle-foot orthosis

BACKGROUND

Compared to able-bodied subjects, subjects with post-polio syndrome and poliomyelitis demonstrate a preference for weight-bearing on the non-paretic limb, causing gait asymmetry.

OBJECTIVES

The purpose of this study was to evaluate the gait symmetry of the poliomyelitis subjects when ambulating with either a drop-locked knee-ankle-foot orthosis or a newly developed powered knee-ankle-foot orthosis.

STUDY DESIGN

Quasi experimental study.

METHODS

Seven subjects with poliomyelitis who routinely wore conventional knee-ankle-foot orthoses participated in this study and received training to enable them to ambulate with the powered knee-ankle-foot orthosis on level ground, prior to gait analysis.

RESULTS

There were no significant differences in the gait symmetry index of step length (p = 0.085), stance time (p = 0.082), double-limb support time (p = 0.929), or speed of walking (p = 0.325) between the two test conditions. However, using the new powered knee-ankle-foot orthosis improved the symmetry index in step width (p = 0.037), swing time (p = 0.014), stance phase percentage (p = 0.008), and knee flexion during swing phase (p ⩽ 0.001) compared to wearing the drop-locked knee-ankle-foot orthosis.

CONCLUSION

The use of a powered knee-ankle-foot orthosis for ambulation by poliomyelitis subjects affects gait symmetry in the base of support, swing time, stance phase percentage, and knee flexion during swing phase.

CLINICAL RELEVANCE

A new powered knee-ankle-foot orthosis can improve gait symmetry for poliomyelitis subjects by influencing step width, swing time, stance time percentage, and knee flexion during swing phase when compared to ambulating with a drop-locked knee-ankle-foot orthosis.

Using a driving simulator during vehicle adaptation

A major drawback with current vehicle modifications is the inability to provide a practice session before driving on the road. Quantitative measurements obtained using a static assembly rig and a virtual driving scenario enabled appropriate adaptive adjustments for a client with post-polio syndrome who complained of difficulties turning the steering wheel. This study describes the assessment process, emphasizing the potential of the system, discussing the limitations of the evaluation and aims to offer occupational therapists an empirical perspective regarding vehicle adaptations for individuals with a physical disability.

Polio survivors' perceptions of the meaning of quality of life and strategies used to promote participation in everyday activities

Introduction

The term ‘post‐polio syndrome’ (PPS) is used to describe new and late manifestations of poliomyelitis that occur later in life. Research in this area has focused upon health status rather than its effect on quality of life.

Aim

To gain an in‐depth understanding of the meaning of quality of life for polio survivors and to determine the type of strategies that are used by people with PPS and the support that they consider as important to facilitate participation in everyday life activities that have an impact on their quality of life.

Method

Six focus groups were conducted with 51 participants from two regions in England. Data were audio‐taped and analysed using thematic analysis.

Results

Our research found that polio survivors used terms used to describe quality of life which could be associated with that of happiness. Our research has identified resolvable factors that influence quality of life namely inaccessible environments, attitudes of health‐care professionals and societal attitudes. Polio survivors have tried alternative therapies, chiefly acupuncture and massage, and found them to be effective in enhancing their quality of life.

Conclusion

It is suggested that health‐care professionals should consider factors which influence happiness and implement a person‐centred approach with the views of the polio survivor being listened to. The three factors that influenced quality of life could be resolved by health‐care professionals and by society. With regard to strategies used, we suggest that polio survivors should have access to the treatments that they perceive as important, although further research is required to design optimal interventions for this client group.

Assistive technology and prediction of happiness in people withpost-polio syndrome

PURPOSE

To explore the relationship between level of happiness in people with post-polio syndrome (PPS) and assistive technology (AT) by taking into account confounding factors such as age, gender and house composition.

METHOD

Existing data from 218 adults with PPS, who had completed a cross-sectional survey conducted by the British Polio Fellowship in 2007, were used for a secondary quantitative analysis. Ordinal logistic regression was applied to determine whether ownership of or the need for AT predicted happiness in people with PPS.

RESULTS

Ownership of AT did not predict happiness, whereas the perceived need for AT was a significant predictor of feeling less happy (p = 0.028). Among the different types of AT needed, only need of home adaptations combined with major equipment was close to being significantly associated with less happiness (p = 0.078). Being older (p < 0.001) and living with a partner (p < 0.001) significantly increased the likelihood of feeling happier.

CONCLUSION

The findings indicate the importance of the contribution of need for AT in explaining happiness in people with PPS. The fact that users reported unmet equipment needs urge for increased user decision making and better understanding of why perceived needs are not resolved. [Box: see text].

Functional and environmental factors affecting work status in individuals with longstanding poliomyelitis

INTRODUCTION

Remunerative employment is a major concern of individuals with chronic disabilities, among them, those with longstanding poliomyelitis (LSP). Although LSP is not rare there are almost no data related to work participation.

PURPOSE

The aims of the current study were to determine the effects of a number of social and functional variables as barriers or facilitators to work participation in persons with LSP.

PATIENTS AND METHODS

Charts of 123 LSP patients of working age that were seen in the post-polio outpatient clinic, between the years 2000 and 2005 were reviewed for the study. Data on age, gender, family status, level of function in activities of daily living, basic, and extended (B-ADL and E-ADL), and mobility were then analyzed for correlation to the vocational status.

RESULTS

Seventy-two people (58.5%) were employed at the time of the survey. Gender and marital status were not found to significantly differ as regard to employment. Using assistive devices for mobility or being dependent for basic ADL were associated with lower levels of employment. Driving was positively associated with the employment status of the LSP individuals.

CONCLUSION

Persons with LSP encounter important barriers to work participation, particularly on the International Classification of Functioning, Disability, and Health (ICF) components of activity and environment.
