Objective-To assess the effects of a community-based exercise program on motor recovery and functional abilities of the paretic upper extremity in persons with chronic stroke.
Design-Randomized controlled trial.
Setting-Rehabilitation research laboratory and a community hall.Participants-A sample of 63 people (≥ 50 years) with chronic deficits resulting from stroke (onset ≥ 1 year).Interventions-The arm group underwent an exercise program designed to improve upper extremity function (1 hour per session, 3 sessions per week for 19 weeks). The leg group underwent a lower extremity exercise program.
Main outcome measures-(1) Wolf Motor Function Test (WMFT), (2) Fugl-Meyer MotorAssessment (FMA), (3) hand-held dynamometry (grip strength), and (4) Motor Activity Log.Results-Multivariate analysis showed a significant group × time interaction (Wilk's Lambda=0.726, P=0.017), indicating that overall, the arm group had significantly more improvement than the leg group. Post-hoc analysis demonstrated that gains in WMFT (functional ability) (P=0.001) and FMA (P=0.001) were significantly higher in the arm group. The amount of improvement was comparable to other novel treatment approaches such as constraint-induced movement therapy or robot-aided exercise training previously reported in chronic stroke. Participants with moderate arm impairment benefited more from the program.Conclusions-The pilot study showed that a community-based exercise program can improve upper extremity function in persons with chronic stroke. This outcome justifies a larger clinical trial to further assess efficacy and cost-effectiveness. There is mounting evidence that both motor and functional changes in the paretic upper extremity can occur many years post stroke with forced use.-Indeed, cortical reorganization has been demonstrated following intensive movement therapy in persons with chronic stroke. Novel approaches such as constraint-induced movement therapy (CIMT)-, repetitive bilateral arm training with rhythmic auditory cueing (BATRAC) and robot-aided exercise training-have been developed to promote paretic upper extremity function following chronic stroke. However, these treatment approaches often involve one-to-one clienttherapist ratio. In case of CIMT, extensive amount of daily therapy is also required.-Considering the current limited health care resources, alternative rehabilitative programs are needed to reduce the long-term disability resulting from upper extremity hemiparesis.A community-based group program may be a feasible alternative approach to upper extremity rehabilitation following a stroke. It is accessible to a large number of people in the community and does not require one-to-one supervision, thereby reducing the cost. The concept of community programs is also compatible with the emerging priority in health care policy to prevent secondary disabilities for persons living with chronic conditions., Community-based programs for promoting mobility and physical fitness in people with chronic stroke have been proposed and po...
