PURPOSE: The purpose of this study was to evaluate the effects of dual-task balance training on stroke patients' balance performance. SUBJECTS AND METHOD: Forty stroke patients were allocated equally and randomly to an experimental group and a control group. The experimental group performed the dual-task balance training of standing on a balance pad and moving a cup containing water. The control group performed the single-task balance training of maintaining balance on a balance pad. All the subjects exercised five times per week for 4 weeks. Each group's balance performance (sway area, sway path, and maximum velocity) was measured using a balance performance monitor, both prior to and after the exercise program. RESULTS: Comparing measurements from before and after the exercise program, both the experimental group and the control group showed statistically significant changes in sway area and maximum velocity, but not for sway path. Comparing the two groups, the experimental group showed more significant changes than the control group in sway area and maximum velocity, but there were no significant differences in sway distance between the two groups. CONCLUSION: For the stroke patients, Dual-task balance training was more effective than single-task balance training. The results should help to promote the wider clinical application of dual-task balance training programs for stroke patients.
