OBJECTIVE: To compare the effects of exergaming with conventional weight-shifting training on balance function in patients with chronic stroke DESIGN: Single-blind randomized controlled trial. SETTING: Rehabilitation department of a medical center. PARTICIPANTS: Patients (n = 30) with chronic stroke and balance deficits. INTERVENTION: Twelve-week Wii Fit training or conventional weight-shifting training. MAIN OUTCOME MEASURES: Static balance was assessed by using posturography. We recorded the stability index and percentage of weight bearing on the affected leg in eight positions. We also used timed-up-and-go and forward reach tests for dynamic balance evaluation, the Falls Efficacy Scale-International questionnaire for fear-of-falling assessment, and physical activity enjoyment scale for estimating the enjoyment of training. RESULTS: The exergaming group showed more improvement in the stability index than the control group in (1) head straight with eyes open on foam surface, (2) eyes closed on solid surface with head turned at 30 degrees to left or (3) with head up positions (time-group interaction p = 0.02, 0.04, and 0.03, respectively); however, the effects were not maintained. At 3-month follow-up, control group showed more improvement in weight-bearing symmetry in the "head straight with eyes open on solid surface" position than the exergaming group (time-group interaction p = 0.03). Both groups showed improvement in timed-up-and-go, forward reach tests, and fear of falling. The improvement in fear of falling was not maintained. The exergaming group enjoyed training more than the control group (p = 0.03). CONCLUSIONS: Exergaming is enjoyable and effective for patients with chronic stroke.
