Background and Purpose: Stroke is a leading cause of long-term disability, and impaired balance after stroke is strongly associated with future function and recovery. Until recently there has been limited evidence to support the use of balance training to improve balance performance in this population. Information about the optimum exercise dosage has also been lacking. This review evaluated recent evidence related to the effect of balance training on balance performance among individuals poststroke across the continuum of recovery. On the basis of this evidence, we also provide recommendations for exercise prescription in such programs. Methods: A systematic search was performed on literature published between January 2006 and February 2010, using multiple combinations of intervention (eg, "exercise"), population (eg, "stroke"), and outcome (eg, "balance"). Criteria for inclusion of a study was having at least 1 standing balance exercise in the intervention and 1 study outcome to evaluate balance. Results: Twenty-two published studies met the inclusion criteria. We found moderate evidence that balance performance can be improved following individual, "one-on-one" balance training for participants in the acute stage of stroke, and either one-on-one balance training or group therapy for participants with subacute or chronic stroke. Moderate evidence also suggests that in the acute stage, intensive balance training for 2 to 3 times per week may be sufficient, whereas exercising for 90 minutes or more per day, 5 times per week may be excessive. Discussion and Conclusions: This review supports the use of balance training exercises to improve balance performance for individuals with moderately severe stroke. Future high-quality, controlled studies should investigate the effects of balance training for individuals poststroke who have severe impairment, additional complications/comorbidities, or specific balance lesions (eg, cerebellar or vestibular). Optimal training dosage should also be further explored. Studies with long-term follow-up are needed to assess outcomes related to participation in the community and reduction of fall risk.
