- BackgroundNo previous studies have investigated what biopsychosocial factors are associated with self‐reported work ability in conservatively managed patients with cervical radiculopathy.ObjectiveTo develop a theoretical model of factors and potential processes associated with variation in work ability based on a thorough assessment of biopsychosocial variables in conservatively managed patients with cervical radiculopathy.DesignCross‐sectional observational study.SettingTertiary neurosurgery clinic.PatientsA total of 144 conservatively managed patients with cervical pain and radiculopathy participated in the study.MethodsFrom 64 biopsychosocial candidate variables, significant (P < .05) bivariate correlators with Work Ability Index (WAI) were entered as independent variables in a categorical regression. Elastic net regularization maintained the most parsimonious set of independent variables significantly associated with variation in WAI as the dependent variable. Process analysis of significant independent variable associations with WAI was performed.Main Outcome MeasurementWAI.ResultsFrom 42 bivariate correlates of WAI, multivariate regression displayed a total of seven variables that were significantly (F [25,98] = 5.74, P < .05) associated with 65.8% of the variation in WAI. The Neck Disability Index (NDI) and Fear‐Avoidance Beliefs Questionnaire Work subscale (FABQ‐W) were significant individual factors within the final regression model. Process analysis displayed FABQ‐W having a significant specific indirect association with the direct association between NDI and WAI, with the model associated with 77% of the variability in WAI (F [2,84] = 141.17, P < .001).ConclusionOf 64 candidate biopsychosocial factors, NDI and FABQ‐W were the most significant multivariate correlates with work ability. FABQ‐W has a significant indirect association with baseline NDI scores and perceived work ability. This warrants future research trialing work‐related fear avoidance interventions in conservatively managed patients with cervical radiculopathy.Level of EvidenceIII

- 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.

- Background: 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.Objective: To evaluate the test-retest reliability of the RNL-I in adults with late effects of polio.Design: A postal survey with a test-retest design.Setting: University hospital outpatient clinic.Participants: Fifty-one adults (20 women and 31 men; mean age 72 years) with late effects of polio.Main Outcome Measurements: The Reintegration to Normal Living Index (RNL-I).Methods: 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%).Results: 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%).Conclusion: 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.

- In August and September of this year, the world will turn its attention to Rio de Janeiro, Brazil, for the 2016 Summer Olympic and Paralympic Games. Of interest to physiatrists, the Paralympic Games will take place from September 7 to 18, with an estimated total of 4 billion viewers. In the United States, for the first time in history, the Summer Games will be broadcast over a total of 66 hours on NBCUniversal. The Paralympic Games represent the pinnacle of elite sport for athletes with disabilities while also changing perceptions around the importance of grassroots sport and physical activity opportunities for the disability community more broadly.It is no secret that the planning and preparation for the Rio Games has brought with it a number of challenges—the Zika virus, water quality, construction delays, and the oft-tenuous state of the Brazilian political system, to name a few. In some respects, these challenges are important as they stimulate discourse about the future of the Olympic and Paralympic Movement. In Paralympic sport, some of our current and most salient challenges are rooted in principles of sports medicine and science, as outlined herein. Because it is imperative to uphold the highest standards of athlete health and safety at the Games, this presents an unparalleled opportunity for the voice of physiatrists to come to the fore. As experts in disability and functional performance, neurologic and musculoskeletal rehabilitation, and sports medicine, we uniquely are suited to make an important and timely impact on Paralympic sport. Here, we provide a snapshot of what to watch out for in Rio.

- 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.

- BackgroundFalls and fear of falling (FOF) are common in persons with late effects of polio but there is limited knowledge of associated factors.ObjectiveTo determine how knee muscle strength, dynamic balance and gait performance (adjusted for gender, age and BMI) are associated with falls and FOF in persons with late effects of polio.DesignA cross-sectional study.SettingA university hospital outpatient clinic.ParticipantsEighty-one ambulatory persons with verified late effects of polio (43 men; mean age 67 years).Main Outcome MeasurementsNumber of falls the past year, Falls Efficacy Scale –International (FES-I) to assess FOF, a Biodex dynamometer to measure knee muscle strength, the Timed Up and Go (TUG) test to assess dynamic balance and the Six Minute Walk test (6MWT) to assess gait performance. Univariate and multivariate logistic regression analyses were used for falls (categorical data) and linear regression analyses for FOF (continuous data) as dependent variables.ResultsFifty-nine % reported at least one fall during the past year and 79% experienced FOF. Reduced knee muscle strength in the more affected limb and gait performance were determinants of falls. An increase of 10 Nm in knee flexor and knee extensor strength reduced the OR between 0.70 and 0.83 (P=.01), and an increase of 100 meter in 6MWT reduced the OR to 0.41 (P=.001). All factors were determinants of FOF; reduced knee muscle strength in the more and less affected limbs explained 17% to 25% of the variance in FOF, dynamic balance 30% and gait performance 41%. Gender, age and BMI only marginally influenced the results.ConclusionsReduced gait performance, knee muscle strength and dynamic balance are to a varying degree determinants of falls and FOF in ambulatory persons with late effects of polio. Future studies need to evaluate if rehabilitation programs targeting these factors can reduce falls and FOF in this population.

- 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

Tidskriftsartikel (refereegranskat)abstract
- Background : 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. Objective: To investigate the measurement properties of FES-I (16-item version) and short FES-I (7-item version) in persons with LEoP. Design: Explorative factor analysis and Rasch model analysis of cross-sectional data. Setting: University Hospital. Participants : A total of 321 persons with LEoP (mean age 70 ± 10 years, 173 women). Main outcome measurement: The FES-I and short FES-I, comprising four response options about concerns of falling ranging from 1 (not at all concerned) to 4 (very concerned). Methods: Data were collected by a postal survey. First, a factor analysis was performed to investigate unidimensionality of the scale. Thereafter, a Rasch model analysis was used to further analyze the measurement properties of FES-I and 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. Results: The factor analysis revealed that FES-I was unidimensional, even though the Rasch analysis showed some misfit to the Rasch model and local dependency. Targeting for FES-I and 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 FES-I and for one item in short FES-I. Reliability was high (PSI >0.86), and the response category thresholds worked as intended for both FES-I, and short FES-I. Conclusion: 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 in this population.
