|
Background and Purpose: To assess effects of training using Visual Biofeedback Program on balance, postural control and functional ability of lower extremities in patients with stroke.
Subjects and Methods: Thirteen stroke patients participated Visual Biofeedback Program training during 4 weeks. Subjects were assigned randomly to either an experimental group (7 patients) or a control group (6 patients). The control group received conventional physical therapy interventions for 30 minutes, 5 times a week. The experimental group trained on the Visual Biofeedback Program (Catch, Skyball, SpeedbalI, Freeze, Target, lmrnobilizer) for 15 minutes, three times in a week during 4 weeks with conventional physical therapy. Subjects were assessed using the Modified Ashworth ScaJe(MAS), the Fugl-Meyer Assessment, the Berg BaJance Scale(BBS), the Functional Ambulation Category Scale, the Timed Up & Go Test(TUG), Comfortable Gait Speed(CGS), Maximal Gait Speed(MGS) and the Postural Assessment Scale for Stroke Patients (PASS) before and after the training.
Results: In the experimental group, there were significant improvement in the BBS, TUG, CGS, MGS and the PASS occurring in the period from baseline to discharge. In the control group, significant improvement were founded in the TUG and the CGS in this period. However, no between-group differences were detected in any of the outcome measures.
Conclusions: Although the training using Visual Biofeedback Program demonstrated improvement in balance, postural control and functional ability of lower extremities for the patients with stroke folIowing 4 weeks of interventions, it was not statistically significant.
