A Community-Based Fitness and Mobility Exercise Program for Older Adults with Chronic Stroke: A Randomized, Controlled Trial

Objectives: To examine the effects of a community‐based group exercise program for older individuals with chronic stroke.

Exercise leads to faster postural reflexes, improved balance and mobility, and fewer falls in older persons with chronic stroke.

Objectives: To determine the effect of two different community‐based group exercise programs on functional balance, mobility, postural reflexes, and falls in older adults with chronic stroke.

Paretic Upper-Limb Strength Best Explains Arm Activity in People With Stroke

Background and Purpose The purpose of this study was to determine the relationship among variables of upper-limb impairment, upper-limb performance in activities of daily living (activity), and engagement in life events and roles (participation) in people with chronic stroke. Subjects The subjects were 93 community-dwelling individuals with stroke (≥1 year). Methods This study, which was conducted in a tertiary rehabilitation center, used a cross-sectional design. The main measures of impairment were the Modified Ashworth Scale, handheld dynamometry, sensory testing (monofilaments), and the Brief Pain Inventory. The main measures of activity were the Chedoke Arm and Hand Activity Inventory (CAHAI) and the Motor Activity Log (MAL). The main measure of participation was the Reintegration to Normal Living (RNL) Index. Results Paretic upper-limb strength (force-generating capacity) (r=.89, P<.01), grip strength (r=.69, P<.01), and tone (resistance to passive movement) (r=−.80, P<.01) were the impairment variables that were most strongly related to activity. Tone (r=−.23, P<.05) and CAHAI scores (r=.22, P<.05) had a significant, but weak, relationship to participation. Upper-limb strength accounted for 87% of the variance of the CAHAI scores and 78% of the variance of the MAL scores. In the participation models, tone and CAHAI scores accounted for 5% of the variance of the RNL Index scores. Discussion and Conclusion Paretic upper-limb strength had the strongest relationship with variables of activity and best explained upper-limb performance in activities of daily living. Grip strength, tone, and sensation also were factors of upper-limb performance in activities of daily living. Increased tone and upper-limb performance in activities of daily living had a weak relationship with participation.

A Self-Administered Graded Repetitive Arm Supplementary Program (GRASP) Improves Arm Function During Inpatient Stroke Rehabilitation A Multi-Site Randomized Controlled Trial

Background and Purpose— More than 70% of individuals who have a stroke experience upper limb deficits that impact daily activities. Increased amount of upper limb therapy has positive effects; however, practical and inexpensive methods of therapy are needed to deliver this increase in therapy. Methods— This was a multi-site single blind randomized controlled trial to determine the effectiveness of a 4-week self-administered graded repetitive upper limb supplementary program (GRASP) on arm recovery in stroke. 103 inpatients with stroke were randomized to the experimental group (GRASP group, n=53) or the control group (education protocol, n=50). The primary outcome measure was the Chedoke Arm and Hand Activity Inventory (CAHAI), a measure of upper limb function in activities of daily living. Secondary measures were used to evaluate grip strength and paretic upper limb use outside of therapy time. Intention-to-treat analysis was performed. Group differences were tested using analysis of covariance. Results— At the end of the 4-week intervention (approximately 7 weeks poststroke), the GRASP group showed greater improvement in upper limb function (CAHAI) compared to the control group (mean difference 6.2; 95% CI: 3.4 to 9.0; P<0.001). The GRASP group maintained this significant gain at 5 months poststroke. Significant differences were also found in favor of the GRASP protocol for grip strength and paretic upper limb use. No serious adverse effects were experienced. Conclusion— A self-administered homework exercise program provides a cost-, time-, and treatment-effective delivery model for improving upper limb recovery in subacute stroke.

Strength Training Improves Upper-Limb Function in Individuals With Stroke: A Meta-Analysis

Background and Purpose— After stroke, maximal voluntary force is reduced in the arm and hand muscles, and upper-limb strength training is 1 intervention with the potential to improve function. Methods— We performed a meta-analysis of randomized controlled trials. Electronic databases were searched from 1950 through April 2009. Strength training articles were assessed according to outcomes: strength, upper-limb function, and activities of daily living. The standardized mean difference (SMD) was calculated to estimate the pooled effect size with random-effect models. Results— From the 650 trials identified, 13 were included in this review, totaling 517 individuals. A positive outcome for strength training was found for grip strength (SMD=0.95, P=0.04) and upper-limb function (SMD=0.21, P=0.03). No treatment effect was found for strength training on measures of activities of daily living. A significant effect for strength training on upper-limb function was found for studies including subjects with moderate (SMD=0.45, P=0.03) and mild (SMD=0.26, P=0.01) upper-limb motor impairment. No trials reported adverse effects. Conclusions— There is evidence that strength training can improve upper-limb strength and function without increasing tone or pain in individuals with stroke.

Individuals with the dominant hand affected following stroke demonstrate less impairment than those with the nondominant hand affected.

Objective. The purpose was to determine if upper extremity impairment and function in individuals with chronic stroke is dependent upon whether the dominant or non-dominant hand is affected. Methods. Ninety-three community-dwelling individuals with stroke. The Modified Ashworth Scale (tone), handheld dynamometry (isometric strength), monofilaments (sensation), Brief Pain Inventory (pain), Chedoke Arm and Hand Activity Inventory Motor Activity Log (paretic arm use), and Reintegration to Normal Living Index (participation) were used to form impairment and function models. Results. Multivariate analysis models (Dominance × Severity) were created for impairment and function variables. There was a significant interaction and main effect of Dominance for the impairment model (P = 0.01) but not the function model (P = 0.75). The dependent variables of tone, grip strength, and pain were all significantly affected by Dominance, indicating less impairment if the dominant hand was affected. All dependent variables except pain were affected by Severity. Conclusion. This study looked at the effect of the dominant hand being affected versus the nondominant in individuals with chronic stroke. Individuals with the dominant hand affected demonstrated less impairment than those with the nondominant hand affected. However, there was no effect of dominance on paretic arm use or performance in activities of daily living. Prospective studies to further explore the issue of hand dominance and poststroke function are suggested.

The International Classification of Functioning as an explanatory model of health after distal radius fracture: A cohort study

BackgroundDistal radius fractures are common injuries that have an increasing impact on health across the lifespan. The purpose of this study was to identify health impacts in body structure/function, activity, and participation at baseline and follow-up, to determine whether they support the ICF model of health.MethodsThis is a prospective cohort study of 790 individuals who were assessed at 1 week, 3 months, and 1 year post injury. The Patient Rated Wrist Evaluation (PRWE), The Wrist Outcome Measure (WOM), and the Medical Outcome Survey Short-Form (SF-36) were used to measure impairment, activity, participation, and health. Multiple regression was used to develop explanatory models of health outcome.ResultsRegression analysis showed that the PRWE explained between 13% (one week) and 33% (three months) of the SF-36 Physical Component Summary Scores with pain, activities and participation subscales showing dominant effects at different stages of recovery. PRWE scores were less related to Mental Component Summary Scores, 10% (three months) and 8% (one year). Wrist impairment scores were less powerful predictors of health status than the PRWE.ConclusionThe ICF is an informative model for examining distal radius fracture. Difficulty in the domains of activity and participation were able to explain a significant portion of physical health. Post-fracture rehabilitation and outcome assessments should extend beyond physical impairment to insure comprehensive treatment to individuals with distal radius fracture.

Goal Priorities Identified through Client-Centred Measurement in Individuals with Chronic Stroke.

PURPOSE: The purpose of this study was to identify goal priorities in a sample of individuals with chronic stroke. METHOD: In this descriptive study involving 19 community-dwelling individuals with stroke, participants were interviewed on the Canadian Occupational Performance Measure (COPM) to ascertain problem areas experienced after hospital discharge. Once problems were identified, they were classified under the three dimensions of the COPM: self-care, productivity, and leisure. RESULTS: The mean time since stroke was 6.8 (±2.9) years. Eighty-four problems were identified within the three dimensions of the COPM. The most frequently cited problems in each dimension were bathing (self-care) by 42% of participants, household maintenance (productivity) by 32% of participants, and walking outdoors (leisure) by 32% of participants. Overall, participants rated their performance of identified problems and satisfaction with their abilities as low and rated each dimension as equally important for problem priority. CONCLUSION: Long after hospital discharge, individuals with chronic stroke were able to identify issues of concern that could benefit from involvement of rehabilitation professionals. Clinicians should be aware that issues of bathing, walking, household maintenance, and recreational activities are of particular importance to people with chronic stroke living in the community. A client-centred approach to problem generation (ie, use of the COPM) may assist in enhancing client involvement and motivation towards rehabilitation.

Self-management interventions for chronic disease: a systematic scoping review

Objective: To investigate the contributions of physiotherapy and occupational therapy to self-management interventions and the theoretical models used to support these interventions in chronic disease. Data sources: We conducted two literature searches to identify studies that evaluated self-management interventions involving physiotherapists and occupational therapists in MEDLINE, the Cochrane Library, CINAHL, EMBASE, AMED (Allied and Complementary Medicine), SPORTdiscus, and REHABDATA databases. Study selection: Four investigator pairs screened article title and abstract, then full text with inclusion criteria. Selected articles (n = 57) included adults who received a chronic disease self-management intervention, developed or delivered by a physiotherapist and/or an occupational therapist compared with a control group. Data extraction: Four pairs of investigators performed independent reviews of each article and data extraction included: (a) participant characteristics, (b) the self-management intervention, (c) the comparison intervention, (d) outcome measures, construct measured and results. Data synthesis: A total of 47 articles reported the involvement of physiotherapy in self-management compared with 10 occupational therapy articles. The type of chronic condition produced different yields: arthritis n = 21 articles; chronic obstructive pulmonary disease and chronic pain n = 9 articles each. The theoretical frameworks most frequently cited were social cognitive theory and self-efficacy theory. Physical activity was the predominant focus of the self-management interventions. Physiotherapy programmes included disease-specific education, fatigue, posture, and pain management, while occupational therapists concentrated on joint protection, fatigue, and stress management. Conclusions: Physiotherapists and occupational therapists make moderate contributions to self-management interventions. Most of these interventions are disease-specific and are most frequently based on the principles of behaviour change theories.

Gender differences in self reported long term outcomes following moderate to severe traumatic brain injury

BackgroundThe majority of research on health outcomes after a traumatic brain injury is focused on male participants. Information examining gender differences in health outcomes post traumatic brain injury is limited. The purpose of this study was to investigate gender differences in symptoms reported after a traumatic brain injury and to examine the degree to which these symptoms are problematic in daily functioning.MethodsThis is a secondary data analysis of a retrospective cohort study of 306 individuals who sustained a moderate to severe traumatic brain injury 8 to 24 years ago. Data were collected using the Problem Checklist (PCL) from the Head Injury Family Interview (HIFI). Using Bonferroni correction, group differences between women and men were explored using Chi-square and Wilcoxon analysis.ResultsChi-square analysis by gender revealed that significantly more men reported difficulty setting realistic goals and restlessness whereas significantly more women reported headaches, dizziness and loss of confidence. Wilcoxon analysis by gender revealed that men reported sensitivity to noise and sleep disturbances as significantly more problematic than women, whereas for women, lack of initiative and needing supervision were significantly more problematic in daily functioning.ConclusionThis study provides insight into gender differences on outcomes after traumatic brain injury. There are significant differences between problems reported by men compared to women. This insight may facilitate health service planners and clinicians when developing programs for individuals with brain injury.
