Background and Purpose The study investigated the effects of balance training with proprioceptive sensory and visual input on functional activity in hemiplegic patients. Subjects and Methods Forty-seven subjects were distributed into three groups: task-oriented balance training (n=15), visual feedback using a Tetrax® posturographic balance assessment and biofeedback device (n=15) and control (n=17). All individuals underwent neuromuscular developmental therapy during 8 weeks. Assessment tools were lower extremity strength (Morticity Index), Berg Balance Scale (BBS), Timed Up & Go Test (TUG), self-selective comfortable gait speed, and Fugl-Meyer Assessment (FMA). Variance was analyzed using one-way ANOVA to detect inter-group differences. Results As following the Results; In comparing inter-group differences, Morticity Index, FMA, and BBS were significantly different between the control group and the task-oriented balance training group (p<.05). TUG (p<.05), and self-selective comfortable gait speed (p<.001) were also significantly different between the control, task-oriented balance training, and visual feedback groups. Conclusion Task-oriented balance training is more effective in improving post-stroke functional ability. A variety of balance training programs that can be done easily and economically following hospital discharge should be developed for patients with post-stroke disabilities.
