Abstract

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 (> or =50y) with chronic deficits resulting from stroke (onset > or =1y).

Interventions: The arm group underwent an exercise program designed to improve upper-extremity function (1h/session, 3 sessions/wk for 19wk). The leg group underwent a lower-extremity exercise program.

Main outcome measures: The Wolf Motor Function Test (WMFT), Fugl-Meyer Assessment (FMA), hand-held dynamometry (grip strength), and the Motor Activity Log.

Results: Multivariate analysis showed a significant group by time interaction (Wilks lambda=.726, P=.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=.001) and FMA (P=.001) scores 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.
