- Exercise-based therapies are the cornerstone of rehabilitation programs. While the benefits of exercise on systemic and tissue function are generally accepted, mechanisms underlying these benefits are sometimes poorly understood. An improved understanding of the effects of mechanical loading on molecular and cellular processes has the potential to lead to more disease-specific and efficacious exercise-based therapies. The purpose of this paper is to review the current literature examining the role of mechanical signaling on muscle and cartilage biology.

- OBJECTIVE: To evaluate the construct validity of a new rating scale for self-reported impairments in persons with late effects of polio. DESIGN: Psychometric analysis of data on self-perceived impairments in persons with prior polio. PARTICIPANTS: Two hundred and seventy-three persons with prior polio (119 men and 154 women; mean age, 63.5 years). METHOD: Rasch analysis of a 13-item rating scale with 5 response categories, in which the participants rated how much they have been bothered by various post-polio-related impairments during the past 2 weeks. RESULTS: The initial analysis showed disordered categories, misfit with some of the items, multidimensionality, and local dependency. After adjustment of the categories, which resulted in a 4-category rating scale, fit to the model was achieved, but the scale still showed signs of multidimensionality. Analyses of local dependency revealed correlations among some of the items, which resulted in a 5 testlet solution, which gave fit to the model and unidimensionality. CONCLUSION: After adjustment of the categories and local dependency, this new rating scale, Self-Reported Impairments in Persons With Late Effects of Polio, can be considered as unidimensional. The good psychometric properties implies that the Self-Reported Impairments in Persons With Late Effects of Polio scale could be a useful rating scale that would increase our understanding of the impairments that persons with late effects of polio can experience. With further refinements, this scale may assist in the planning and evaluation of appropriate rehabilitation interventions.

Tidskriftsartikel (refereegranskat)abstract
- Stroke is a leading cause of long-term disability. The physical and cognitive impairments after an ischemic or hemorrhagic stroke often lead to activity limitations and participation restrictions. Many persons after stroke have a sedentary lifestyle, are physically inactive, and have a low fitness level. Physical fitness training is known to be beneficial for persons with a number of comorbid conditions or risk factors for stroke. Although exercise and physical activity are considered valuable, the evidence of their benefits after stroke is still insufficient. In this review, we summarize published randomized controlled trials regarding the effects of cardiorespiratory fitness and muscle-resistance training after stroke on physical function, activity, participation, life satisfaction, and mood. We discuss various barriers that can impede the ability to perform exercise, and the importance of reducing these barriers to increase physical fitness levels after the completion of usual stroke rehabilitation, thereby enhancing leisure, well-being, and participation in society

- Objective: To assess self-reported walking ability in individuals with chronic stroke and to determine the relationship with gait performance tests. Design: Descriptive analysis of a convenience sample. Setting: A university hospital rehabilitation medicine clinic. Participants: Fifty ambulatory community-dwelling poststroke individuals (mean age, 64 years [range, 44-74 years] and mean time since stroke onset 42 months [range, 6-101 months]). Main Outcome Measures: The Walking Impact Scale (the Walk-12) to assess self-reported walking ability, and the Timed "Up & Go" test, 10-m Comfortable Gait Speed and Fast Gait Speed tests, and 6-Minute Walk Test to assess gait performance. Results: A majority of the participants (94%) reported limitations in their walking ability. The most common limitations were related to standing or walking, walking speed and distance, effort, and gait quality aspects. The ability to run was reported as most affected, whereas the need for support indoors or outdoors was least affected. Significant correlations (. P < .01) were found between the Walk-12 and the 4 gait performance tests (ρ = -0.60 to 0.60). Conclusions: Persons with chronic stroke perceive limitations in their walking ability. The relationship between the Walk-12 and the 4 gait performance tests indicates that self-reports and quantitative assessments are associated. Because the Walk-12 reflects broader dimensions than the gait performance tests, it can be a complementary tool when walking ability in persons with chronic stroke is evaluated.

- To be able to evaluate recovery, effects of rehabilitation interventions and changes over time, reliable and valid outcome measures are needed. The ABILHAND Questionnaire is a measure of self-reported ability to perform complex daily hand activities. It is commonly used in stroke rehabilitation, but data about the measurement variability are missing.

- OBJECTIVE: To assess the reliability of 4 gait performance tests in individuals with late effects of polio. DESIGN: An intrarater (between occasions) test-retest reliability study. SETTINGS: University hospital. PARTICIPANTS: Thirty men and women (mean age 63 +/- 6.4 years) with clinically and electrophysiologically verified late effects of polio. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: The Timed "Up & Go" test, the Comfortable and the Fast Gait Speed tests, and the 6-Minute Walk test were assessed 7 days apart. Reliability was evaluated with the intraclass correlation coefficient (ICC(2,1)), the mean difference between the test sessions (d), and the 95% confidence intervals for d, the standard error of measurement (SEM and SEM%), the smallest real difference (SRD and SRD%) and the Bland & Altman graphs. RESULTS: Test-retest agreements were high (ICC(2,1) 0.82-0.97) and measurement errors generally small. The standard error of measurement (SEM%), representing the smallest change that indicates a real (clinical) improvement for a group of individuals, was small (4%-7%). The smallest real difference (SRD%), representing the smallest change that indicates a real (clinical) improvement for a single individual also was small (12%-21%). CONCLUSION: These commonly used gait performance tests are highly reliable and can be recommended to evaluate improvements in various aspects of gait performance in groups of individuals as well as single individuals with late effects of polio.

- OBJECTIVE: To assess the reproducibility of the Berg Balance Scale (BBS) and the Single-leg Stance (SLS), and the validity of the SLS as an independent test of upright postural control in patients with chronic stroke. DESIGN: An intra-rater test-retest reproducibility study. The BBS and the SLS were assessed twice, 7 days apart. SETTING: A university hospital. PARTICIPANTS: Fifty individuals; 6-46 months after a stroke. MAIN OUTCOME MEASUREMENTS: The reproducibility of the BBS and the SLS was evaluated with intraclass correlation coefficient (ICC(2,1)), the mean difference between the 2 test sessions (d̄) with 95% confidence interval (95% CI), the standard error of measurement (standard error of measurement [SEM]%), the smallest real difference (SRD%), and the Bland-Altman graphs. To assess validity of SLS, the relationship between the SLS and the BBS was analyzed by the Pearson correlation coefficient. RESULTS: The ICC(2,1) was 0.88 for the BBS, and the ICC(2,1) values were 0.88 for the nonparetic limb and 0.92 for the paretic lower limb for the SLS. The smallest change that indicates a real improvement for a group of individuals, SEM%, was 3% for BBS, 15% for the nonparetic limb and 27% for the paretic limb for SLS. The smallest real difference for a single individual was 8% for BBS but was higher for SLS, at 42% for the nonparetic limb, and 74% for the paretic limb. There was a significant relationship between the SLS and the BBS (r = 0.65-0.79; P < .001). CONCLUSIONS: The BBS and the SLS are reproducible measurements in patients with chronic stroke, but only the BBS is sensitive enough to follow changes over time or after an intervention. The SLS is strongly related to the BBS and can be used as an independent test to measure upright postural control after a stroke.

Content Analysis of Four Fear of Falling Rating Scales by Linking to the International Classification of Functioning, Disability and Health.
- 2013

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To gain a deeper understanding of the content of 4 fear of falling (FOF) rating scales by linking them to the International Classification of Functioning, Disability and Health (ICF). DESIGN: Linking study according to the ICF linking rules. SETTING: Not applicable. PATIENTS: Not applicable. METHODS: The rating scales were the Falls Efficacy Scale-International (FES-I), the Swedish version of the Falls Efficacy Scale (FES[S]), the Activities-specific Balance Confidence Scale (ABC), and the modified Survey of Activities and Fear of Falling in the Elderly (SAFFE). The process followed the established and updated linking rules. Three linkers independently identified all meaningful concepts in the rating scales and linked them to the most precise ICF categories. The linkers then discussed their results to reach consensus. If consensus was not attained, the linkers pursued the discussions with a fourth person to reach consensus. MAIN OUTCOME MEASUREMENTS: Not applicable. RESULTS: Most meaningful concepts from the overall questions were linked to the ICF component of body functions. Of the 62 items, all but one meaningful concept were linked to the component of activities and participation. All 4 rating scales covered the chapters of mobility and domestic life and had most linkages to the mobility chapter. CONCLUSIONS: The linking process revealed similarities and differences between the 4 FOF rating scales, as well as methodologic challenges in linking instruments to the ICF. By providing a content description that allows for a direct comparison of the rating scales, the results may be helpful when choosing an appropriate rating scale assessing FOF in clinical practice and research. A further head-to-head comparison through psychometric analyses is required to recommend appropriate FOF rating scales. Studies are also needed to investigate how the overall question and response categories of a rating scale affect respondents' answers.
