Two-year course of walking adaptability in persons living with late effects of polio.

To evaluate the 2-year course of walking adaptability in persons with late effects of polio. Prospective cohort study. A total of 48 persons with late effects of polio (69% female, mean age 63.1 years) with a fall history and/or fear of falling. Walking adaptability (i.e. variable target-stepping and reactive obstacle-avoidance) was assessed on an interactive treadmill at baseline, 1 year and 2 years. Further, leg-muscle strength and balance were assessed at baseline. The course of walking adaptability was analysed with linear mixed models. Based on median values, subgroups were defined for low vs high baseline walking-adaptability and for clinical characteristics. Tme by subgroup interactions were analysed. Variable target-stepping and reactive obstacle-avoidance did not change (p > 0.285). Reactive obstacle-avoidance improved for persons with a high balance score at baseline (p = 0.037), but not for those with lower scores (p = 0.531). No other time by subgroup interactions were found (p > 0.126). Walking adaptability did not change in persons with late effects of polio over 2 years, and walking adaptability course did not differ between subgroups stratified for walking adaptability determinants, except for balance. Since falls are a major problem among persons with late effects of polio, future studies should investigate whether walking adaptability declines over a longer time and which persons are most at risk.

Changes in self-perceived performance and satisfaction with performance of daily activities following interdisciplinary rehabilitation in people with late effects of polio.

People with late effects of polio (LEoP) may need rehabilitation to manage everyday life but knowledge of the benefits of interdisciplinary rehabilitation is limited. To evaluate changes in performance and satisfaction with performance of activities among people with LEoP following interdisciplinary rehabilitation. A pre-post retrospective study based on data on 102 participants with LEoP from a rehabilitation clinic. Changes in performance and satisfaction with performance of daily activities before and after interdisciplinary rehabilitation were assessed with the Canadian Occupational Performance Measure (COPM). There were statistically significant increases in the mean performance and mean satisfaction with performance COPM scores from admission to discharge. Twenty-three percent and 19% of the participants, respectively, had improved their performance and satisfaction with performance, 25% and 26% of the participants had no changes, and 19% and 22% of the participants, respectively, rated their performance and satisfaction lower at discharge compared to admission. Interdisciplinary rehabilitation can enhance self-rated performance and satisfaction with performance of daily activities among people with LEoP. Future studies of rehabilitation for people with LEoP should use a prospective design and capture the participants' process of change related to their rehabilitation period.

Late effects of polio: Interviewing general practitioners and health professionals about the need for and the means of promoting continuing professional development.

Polio Australia estimates tens of thousands of polio survivors are experiencing late effects of polio (LEoP), including increased cases among young women of childbearing age in some migrant communities. Because polio has been declared eradicated in Australia, the provision and uptake of education by general practitioners (GPs) and healthcare professionals (HCPs) is minimal. We explored the awareness of LEoP among HCPs and ways to enhance knowledge dissemination toimprove clinical practice. A qualitative study was undertaken, informed by a descriptive (transcendental) phenomenological approach. Semistructured interviews were audio recorded, transcribed and analysed inductively, with a conciliation among the research team used to finalise the themes. HCPs expressed the importance of learning about LEoPand how this may help build supportive patient-practitioner relationships and contribute to patient outcomes. Factors influencing the uptake of professional development included motivation, possibly stemming from a lack of awareness of LEoP, together with the timeand logistical limitations of practice generally. Online learning activities followed by an assessment maybe attractive for some HCPs, but peer-based and multidisciplinary continuing professional development activities remain preferred.

Measurement properties of the Falls Efficacy Scale-International (FES-I) in persons with late effects of polio: A cross-sectional study.

Fear of falling (FoF) is very common in persons with late effects of polio (LEoP). An internationally recognized rating scale to assess FoF is the Falls Efficacy Scale-International (FES-I). Yet, there is limited knowledge about its measurement properties in persons with LEoP. To investigate the measurement properties of the FES-I (16-item version) and the short FES-I (7-item version) in persons with LEoP. Explorative factor analysis and Rasch model analysis of cross-sectional data. University hospital. A total of 321 persons with LEoP (mean age ± standard deviation [SD] 70 ± 10 years, 173 women). The FES-I and the short FES-I, comprising four response options about concerns of falling ranging from 1 (not at all concerned) to 4 (very concerned). Data were collected by a postal survey. First, a factor analysis was performed to investigate the unidimensionality of the scale. Thereafter, a Rasch model analysis was used to further analyze the measurement properties of the FES-I and the short FES-I, such as local dependency, targeting, hierarchical order of items, Differential Item Functioning (DIF), response category functioning and reliability (Person Separation Index, PSI). Raw score transformation to interval measurements was also performed. The factor analysis revealed that the FES-I was unidimensional, even though the Rasch analysis showed some misfit to the Rasch model and local dependency. Targeting for the FES-I and the short FES-I was somewhat suboptimal as the participants on average reported less FoF than expected. A negligible gender DIF was found for two items in the FES-I and for one item in the short FES-I. Reliability was high (PSI >0.86), and the response category thresholds worked as intended for both the FES-I and the short FES-I. The FES-I and the short FES-I have sufficient measurement properties in persons with LEoP. Both versions can be used to assess fear of falling (or FoF) in this population.

The Influence of Walking Limitations on Daily Life: A Mixed-Methods Study of 14 Persons with Late Effects of Polio.

Reduced walking ability is common in persons with late effects of polio (LEoP). Here, we explored how many walking limitations persons with LEoP perceive, and how these limitations influence daily life, by using a mixed-methods design. Fourteen persons (mean age 70 years, whereof 7 women) with LEoP responded to the Walking Impact Scale (Walk-12), and were interviewed individually. Qualitative data were analysed by systematic text condensation, and each quotation was deductively analysed in relation to the items in Walk-12. Running was perceived as most limited, whereas walking indoors without using support was perceived as least limited. A majority (>70%) were moderately to extremely limited in standing or walking, in walking speed and distance, which affected concentration and effort, as well as gait quality aspects. The limited walking ability intruded on many everyday activities, both indoors and outdoors, which affected social participation negatively. To increase safety when walking and reduce the fall risk, various strategies were adopted such as using aids, walking carefully, and avoiding risky activities. In conclusion, LEoP-related walking limitations influence participants’ activity and participation greatly. By using both the Walk-12 scale and face-to-face interviews, an increased understanding of how walking limitations influence everyday life was achieved.

The Meaning of Sense of Coherence (SOC) in Persons with Late Effects of Polio-A Qualitative Study.

Sense of Coherence (SOC), comprising comprehensibility, manageability and meaningfulness, is important for the sense of living a good life with Late Effects of Polio (LEoP). However, there is a lack of knowledge about the meaning of these three components. The aim of this study was to explore in-depth the meaning of SOC among persons living with LEoP, in terms of comprehensibility, manageability and meaningfulness. A directed content analysis was performed based on individual interviews with 7 men and 7 women with LEoP (mean age 73 years). SOC in persons with LEoP existed in two overarching themes that were closely intertwined: a state of motion and a state of being. The state of motion comprised active approaches, choices and actions, and was a process aimed at achieving a stronger comprehensibility, manageability and meaningfulness. The state of being comprised the comprehensibility, manageability and meaningfulness that the persons currently experienced. A profound understanding of SOC as both a state of motion and state being is essential for rehabilitation professionals when providing self-management support to persons living with LEoP. This understanding can increase their sense of living a good life and also be used in the rehabilitation of other life-long conditions.

Sense of coherence and coping behaviours in persons with late effects of polio

Sense of coherence (SOC), comprising "comprehensibility", "manageability" and "meaningfulness", is important for successful adaptation in persons with late effects of polio (LEoP) and can be used as an estimate of the ability to cope with stressors. Coping behaviours are the actions a person performs to reduce stress and can be divided into problem-focused coping, emotion-focused coping and less useful coping. Our knowledge is very limited of what coping behaviours persons with LEoP use to manage their life situation as well as the association between SOC and coping behaviours. The aims of this cross-sectional study were to assess coping behaviours and to explore the association between SOC and coping behaviours in persons with LEoP. In total, 93 ambulant persons (52% women, mean [SD] age 74 [8] years) with clinically and electromyographically verified LEoP responded to a postal survey with the Sense of Coherence Scale 13 items (SOC-13) and the Brief Cope Scale. Three linear regression analyses were used to explore the association between SOC and problem-focused coping, emotion-focused coping and less useful coping, controlling for age and sex. The most-used coping behaviours belonged to the categories problem-focused and emotion-focused coping. We found a significant negative association between SOC and less useful coping; less useful coping explained 34% of the variance of SOC (adj R2=0.34, p<0.001), whereas age and sex were not significant in the analyses. Persons with LEoP primarily use problem-focused and emotion-focused coping behaviours, which suggests that generally they have adapted well to their disability. Regardless of age and sex, persons with lower SOC scores use less useful coping behaviours, which suggests that they are not as well adapted. These results can facilitate the development of rehabilitation interventions that help persons with LEoP adapt to their situation with a life-long disability.

Fall-Related Activity Avoidance among Persons with Late Effects of Polio and Its Influence on Daily Life: A Mixed-Methods Study.

Falls are common among persons with late effects of polio (LEoP), which may lead to fear of falling and activity avoidance in everyday life. Here, we assessed the occurrence of fall-related activity avoidance among persons with LEoP and explored how these experiences influenced daily life. Fourteen ambulatory persons (seven women; mean age 70 years) with LEoP participated. They responded to the modified Survey of Activities and Fear of Falling in the Elderly (mSAFFE) and participated in individual interviews, which were analysed by systematic text condensation. Each quotation was deductively analysed from its representation with regard to mSAFFE. We found that many persons often avoided activities related to standing and walking, for example, taking a bath, performing household chores, walking outdoors, attending social events if there were stairs in the building and travelling by public transport, due to fear of falling, increased pain and fatigability. To facilitate the performance of daily activities participants expressed that strategic thinking and aids were important to use. In conclusion, fall-related activity avoidance is common in persons with LEoP, which negatively influence daily life and social participation. To increase daily functioning in this population, fall-related activity avoidance should be included in a multifaceted fall management program.

Effects of muscle strengthening and cardiovascular fitness activities for poliomyelitis survivors: A systematic review and meta-analysis.

ObjectiveTo evaluate and assess the effectiveness of muscle strengthening and cardiovascular interventions in improving outcomes in poliomyelitis (polio) survivors.Data sourcesA systematic literature search was conducted in Medline, PubMed, CINAHL, PsychINFO, Web of Science, and Google Scholar for experimental and observational studies.Study selection and extractionScreening, data-extraction, risk of bias and quality assessment were carried out independently by the authors. The quality appraisal and risk of bias were assessed using the Downs and Black Checklist. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed to increase clarity of reporting.Data synthesisA total of 21 studies that met all the inclusion criteria were subjected to statistical analyses according to intervention (muscle strengthening or cardiovascular fitness). A random-effects metaanalysis showed a statistically significant effect for the exercise interventions favouring improvement in outcomes according to the International Classification of Functioning, Disability and Health (ICF).ConclusionThis review provides further insight into the effects associated with muscle strengthening and cardiovascular interventions among polio survivors, and helps to further identify the current state of research in this area. Future research is needed, focusing on individualized approaches to exercise with polio survivors and specific exercise prescription recommendations, based on established frameworks, such as the ICF.LAY ABSTRACTPolio survivors are an ageing population and prone to functional decline. Multiple age-related diseases affect this population, in addition to Late Effects of Polio (LEoP). Exercise plays an important role in improving strength and overall cardiovascular fitness in these individuals, and clinicians face challenges when advising polio survivors on the optimal level of exercise to avoid producing pain and/or fatigue. Improvements in strength and cardiovascular fitness have the potential to translate into activities of daily living within this cohort. To our knowledge, this is the first systematic review and meta-analysis using a broad approach (i.e. including both experimental and observational studies) to capture and summarize the research to date regarding the role of muscle strengthening and aerobic conditioning exercise in polio survivors. This review provides valuable information for clinicians, which will help enable the development of specific exercise prescription appropriate to this population.

Psychometric Properties of the Walking Impact Scale (Walk-12) in Persons with Late Effects of Polio.

Many persons with late effects of polio (LEoP) perceive walking limitations in everyday life. A common rating scale to assess walking limitations is the Walking Impact Scale (Walk-12). However, there is limited knowledge about its psychometric properties. To investigate the psychometric properties of Walk-12 in persons with LEoP. Rasch model analysis of cross-sectional data. University hospital. A total of 325 persons with LEoP (175 women; mean age 70 ± 10 years). The Walk-12, comprising 12 items with five response categories ranging from 1 (not at all) to 5 (extremely). Data of Walk-12 were collected by a postal survey. The Rasch model analysis was used to analyze unidimensionality of the scale, local dependency, targeting, hierarchical order of items, Differential Item Functioning (DIF), response category functioning, and reliability (Person Separation Index, PSI). Raw score transformation to interval measurements was also performed. The analysis revealed that Walk-12 was multidimensional and suffered from some local dependency. Targeting was compromised among persons with less and more walking limitations. Hierarchically, the most difficult item to perform was "running" and the easiest was "walking indoors with support". There was a minor DIF for gender in one item ("support when walking outdoors"). Reliability was high (PSI = 0.94). Disordered response category thresholds were found for three items; when merging the middle response categories for these items model fit slightly improved and unidimensionality was achieved. The Walk-12, in its current version, does not fully meet the rigorous psychometric Rasch measurement standards in persons with LEoP. Further development of the scale is warranted, including merging response categories and complementing Walk-12 with objective measures of gait in order to improve targeting. As these limitations can be considered minor, the current version of Walk-12 can still be useful for research and clinical practice.

Life Satisfaction in Persons With Late Effects of Polio: A Test-Retest Reliability Study.

The Life Satisfaction Questionnaire (LiSat-11), including one global item and 10 domain-specific items, is used to evaluate life satisfaction in persons with the late effects of polio (LEoPs). However, there is a lack of knowledge about its psychometric properties. To evaluate the test-retest reliability of the LiSat-11 and the associations between the global and domain-specific items in persons with LEoPs. A test-retest design, where data were collected by a postal survey. University Hospital, Outpatient Clinic. A cross-sectional sample of persons (20 women and 31 men; mean age 72 years) with LEoPs. LiSat-11, assessing how satisfied a person is with different aspects of life, such as life as a whole, vocation, economy, leisure, contacts with friends and acquaintances, sexual life, activities of daily living (ADLs), family life, partner relationship, somatic health, and psychological health. LiSat-11 was administered on two occasions, 2 weeks apart. The test-retest reliability was evaluated by Kappa statistics, the percent agreement (PA), and the Svensson rank-invariant method. The association between the items was evaluated with the Spearman rank correlation coefficient (rho). The Kappa coefficients showed good to excellent agreement (0.64-0.90) and the PA ≤1 point was high (>92%) for all items. No items showed any systematic or random disagreements according to the Svensson method. All domain-specific items correlated significantly with the global item "Life as a whole" (P < .01; rhos 0.41 to 0.75). LiSat-11 is reliable for assessing life satisfaction in persons with LEoPs. The global item "Life as a whole" is useful as an overall measure but cannot fully replace the information obtained from the domain-specific items of LiSat-11.

A very long-term longitudinal follow-up of persons with late effects of polio.

As many as 60-80% of persons with a history of polio myelitis develop new symptoms, such as new or increased muscle weakness, muscle and joint pain, and fatigue several decades later, called postpolio syndrome (PPS). This may affect their ability to perform activities of daily living (ADL). It is still unclear if the patient's symptom is getting worse and in that case how much/fast the decline is. The aim of the present study was to evaluate long-term changes in disability in community dwelling patients with prior poliomyelitis, in contact with a polio clinic 14-16 years post their first assessment. A cross sectional longitudinal study. Polio clinic. Fifty-two persons recruited from an earlier 4-year follow-up participated in the study. A questionnaire was mailed prior to the visit at the polio clinic. Physical testing was performed by measuring muscle strength, walking speed and handgrip force. Overall there was a small change in muscle strength. A significant reduction in the right leg was found for flexion 60° and in dorsal flexion. For the left leg a significant reduction was found for plantar flexion. In the walking tests, a significant reduction was seen for spontaneous walking speed. No significant interaction between decrease in spontaneous walking speed and the variables age, BMI and flexion 60° and dorsal flexion in the right leg was seen. This cross-sectional longitudinal study shows small changes in muscle strength and disability. The results may imply that symptoms associated with late effects of polio are not progressing as fast as we had previously thought. When health care professionals meet persons with late effects of polio the knowledge of long-term consequences of deterioration is important. Knowing that the deterioration is not as fast as previously thought, can help us to support the person in having a healthy lifestyle, stay active and encourage to perform adapted physical training.

Self-reported impairments among people with late effects of polio: a mixed-methods study.

To determine how much people with late effects of polio are bothered by various impairments and their influence on everyday life. A mixed-methods design. Seven women and 7 men (mean age 70 years) with late effects of polio. Self-reported Impairments in Persons with late effects of Polio (SIPP) scale and face-to-face interviews. In SIPP, the participants rated, from 1 (not at all) to 4 (extremely), how much they had been bothered by late effects of polio-related impairments. Qualitative data were analysed using systematic text condensation. Each quotation was deductively analysed based on its conceptual representation regarding perceived influence on everyday life. Participants were most bothered by muscle and/or joint pain during physical activity, muscle weakness and general fatigue, which corresponded with the number of interview quotations. The impairments negatively influenced daily life, such as household chores, walking, riding a bicycle and social participation. Increased impairments and reduced functioning on the less-affected side also caused worry and distress. Common late effects of polio-related impairments greatly affected participants' activity and participation. By using both the SIPP scale and face-to-face interviews, an increased understanding of how late effects of polio-related impairments influence everyday life was achieved.

Growing up with a disability following paralytic poliomyelitis: experiences from persons with late effects of polio

Purpose To describe the experiences of growing up after acute paralytic poliomyelitis and strategies used to adapt to the new situation. Methods Seven women and seven men (mean age 70 years, min–max 61–78 years) with late effects of polio, who had contracted paralytic polio in their childhood. Data were collected using semi-structured interviews, transcribed verbatim, and analyzed by systematic text condensation. Results Memories of contracting acute paralytic poliomyelitis involved being immobilized and sent away from home for surgical and physiotherapeutic treatment. Growing up in a social context that was often tough and unfriendly resulted in the development of strategies, such as optimistic thinking, trying to blend in, trusting one’s ability to manage, and to handle the preconceptions and expectations of others. At the onset of late effects of polio, some of these strategies were still functioning, whereas overachieving, disregarding pain, and weariness were not. Conclusion The challenges of growing up with a disability following paralytic polio led to the development of various psychological strategies for managing daily life. By understanding these experiences and strategies, knowledge may be gained in assisting rehabilitation professionals to better support persons with late effects of polio in adapting to the new situation. Implications for rehabilitation At the onset of late effects of polio, strategies developed earlier in life, such as overachieving, disregarding pain, and weariness, may not function anymore. Understanding the experiences of growing up with poliomyelitis can support rehabilitation professionals to provide targeted interventions for people with late effects of polio and enable them to develop new adaptive strategies. Developing new strategies, such as accepting increased symptoms, and augmenting self-esteem and self-efficacy, may improve daily functioning among people with late effects of polio.

Sense of Coherence and the Association with Sociodemographics and Disability Related Factors in Persons with Late Effects of Polio.

Sense of Coherence (SOC) is important for successful adaptation in persons with life-long disabilities. A previous study has shown that persons with Late Effects of Polio (LEoP) have a level of SOC indicating that they generally have the ability to understand, handle, and have the motivation to deal with stressful events and problems arising in their lives. However, no study has explored the associations between SOC, sociodemographics, and disability-related factors in persons with LEoP. To explore the associations between SOC, sociodemographics, and disability-related factors in persons with LEoP. A cross-sectional design. University hospital outpatient clinic. Ninety-three persons (mean age 74 years, 52% women) with LEoP. Swedish versions of the Sense of Coherence scale (SOC-13), Self-reported Impairments in Persons with Late Effects of Polio (SIPP) scale, Reintegration to Normal Living Index (RNL-I) (subscales "Daily Functioning" and "Perceptions of Self"), and Satisfaction With Life Scale (SWLS). The participants responded to a postal survey with background information and the four rating scales. To determine factors associated with SOC, a hierarchical regression analysis was performed with SOC as the dependent variable. Higher age, less bothered by symptoms of LEoP, better perceptions of self, and higher life satisfaction were significantly associated with a greater SOC score. The final model explained 60% of the variance in the SOC (R2 Adj = 0.60, P < .001). The strong association between SOC, higher age, and disability-related factors is important to consider in the rehabilitation of persons with LEoP. This knowledge can assist rehabilitation professionals to plan interventions that enable people with LEoP to develop strategies to better manage their daily life. III.

Test-Retest Reliability of the Reintegration to Normal Living Index (RNL-I) to Assess Perceived Participation in Adults With Late Effects of Polio.

Many individuals with late effects of polio have difficulties participating in daily activities. The Reintegration to Normal Living Index (RNL-I) is a self-report questionnaire that evaluates perceived participation, but knowledge of the test-retest reliability and measurement errors in this population is lacking. To evaluate the test-retest reliability of the RNL-I in adults with late effects of polio. A postal survey with a test-retest design. University hospital outpatient clinic. Fifty-one adults (20 women and 31 men; mean age 72 years) with late effects of polio. The Reintegration to Normal Living Index (RNL-I). The participants responded to the RNL-I twice, 3 weeks apart. Data were analyzed with the following statistical methods: percentage agreement (PA), quadratic kappa coefficients, the intraclass correlation coefficient (ICC), mean difference, standard error of measurement (SEM/SEM%), and the smallest real difference (SRD/SRD%). The PA (ie, the same scoring at both test occasions) was >70% for 10 of 11 items. The kappa coefficients showed good test-retest agreement (>0.61) for 7 items. The ICC was 0.88 and the mean difference was -0.74. The SEM (SEM%) was 7.4 (9.7%) and the SRD (SRD%) was 20.5 (27.0%). The RNL-I can be considered reliable for adults with mild to moderate late effects of polio. It can thereby be used to assess changes in perceived participation over time or after rehabilitation interventions, both for a group of individuals and a single individual. III.

The Benefit of a Flexible Ankle-Foot Orthosis on Balance and Walking Ability in Persons With Late Effects of Polio: A Mixed-Methods Study

ABSTRACT Introduction Many persons with late effects of polio (LEoP) have muscle weakness in the lower limbs, which affects their balance and walking ability. Although an ankle-foot orthosis (AFO) is commonly prescribed for these persons, there is limited knowledge if an AFO improves their balance and walking ability in terms of speed, distance, and perceived safety. The aims of this study were 1) to assess if a flexible AFO improves dynamic balance as well as indoor and outdoor walking in persons with mild to moderate LEoP and 2) to describe the participants' own perceptions of walking ability and safety, as well as advantages and disadvantages with an AFO. Materials and Methods A mixed-methods, repeated-measures, crossover design was used. Nineteen participants were assessed at two test occasions, with and without an AFO, with a 1-week interval. Dynamic balance was evaluated with the timed up and go (TUG) test and walking ability by the 10-m fast gait speed (FGS) tests, the 6-minute walk test (6MWT), and timed walking over a 340-m-long pathway outdoors. The Borg Rating of Perceived Exertion (RPE) scale was used to assess perceived exertion. The participants' perceptions of their walking ability and safety as well as advantages and disadvantages with an AFO were evaluated with questionnaires. Results The AFO significantly improved (P &lt; 0.05) gait speed, outdoor walking, and reduced perceived exertion at one of the test occasions, but had no effect on dynamic balance (P &gt; 0.6). A majority perceived significantly improved walking ability (P &lt; 0.05) and increased walking safety (P &lt; 0.01) with the AFO. Perceived advantages of the AFO were feelings of increased stability and walking distance and reduced risk of falling. Disadvantages were that it could be difficult to put on and uncomfortable to wear. Conclusions A flexible AFO marginally improves walking ability in persons with LEoP, as assessed quantitatively, but the subjective benefit of walking ability and safety suggests that a flexible AFO can be useful to improve daily functioning. In the future, the design of the AFOs needs to be more user-friendly.

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.

Psychometric Properties of Three Fatigue Rating Scales in Individuals With Late Effects of Polio.

ObjectiveTo evaluate the psychometric properties of the Fatigue Severity Scale (FSS), the Fatigue Impact Scale (FIS), and the Multidimensional Fatigue Inventory (MFI-20) in persons with late effects of polio (LEoP). More specifically, we explored the data completeness, scaling assumptions, targeting, reliability, and convergent validity.MethodsA postal survey including FSS, FIS, and MFI-20 was administered to 77 persons with LEoP. Responders received a second survey after 3 weeks to enable test-retest reliability analyses.ResultsSixty-one persons (mean age, 68 years; 54% women) responded to the survey (response rate 79%). Data quality of the rating scales was high (with 0%–0.5% missing item responses), the corrected item-total correlations exceeded 0.4 and the scales showed very little floor or ceiling effects (0%–6.6%). All scales had an acceptable reliability (Cronbach’s α ≥0.95) and test-retest reliability (intraclass correlation coefficient, ≥0.80). The standard error of measurement and the smallest detectable difference were 7%–10% and 20%–28% of the possible scoring range. All three scales were highly correlated (Spearman’s correlation coefficient rs=0.79–0.80; p<0.001).ConclusionThe FSS, FIS, and MFI-20 exhibit sound psychometric properties in terms of data completeness, scaling assumptions, targeting, reliability, and convergent validity, suggesting that these three rating scales can be used to assess fatigue in persons with LEoP. As FSS has fewer items and therefore is less time consuming it may be the preferred scale. However, the choice of scale depends on the research question and the study design.

Sense of Coherence in persons with late effects of polio.

Sense of Coherence (SOC) is important for successful adaptation and mental well-being in people with life-long medical conditions. Late effects of polio (LEoP) often lead to a life-long disability, but no study has assessed SOC in this population. To assess SOC in persons with LEoP and to explore the association between SOC, demographics (age, gender, marital status and level of education) and variables related to LEoP (age at polio onset, number of years from polio until onset of LEoP and self-rated disability). Ninety-three community-dwelling persons with clinically verified LEoP responded to a postal survey with the Sense of Coherence Scale (SOC-13). A hierarchical multiple regression analysis was performed to explore the associations with SOC. SOC varied considerably among the participants. The mean and median SOC-13 total sum score was 71.8 and 76 points, which is similar to age-matched non-disabled people. The number of years before onset of LEoP and self-rated disability together with the participants' marital status and level of education explained 37% (p < 0.001) of the variance in SOC. Persons with LEoP have a level of SOC indicating that they generally have the ability to understand, handle and being motivated when dealing with stressful events and problems arising in their lives as a result of their disability. Being married and having a higher education, living many years before onset of LEoP and perceiving a mild to moderate disability contributed to a strong SOC.
