PURPOSE: The purpose of this study was to investigate the effects of visual feedback training (VFT) in the sitting position on sitting balance ability and visual perception of chronic stroke patients. SUBJECTS: Twenty-two hospitalized subjects who had experienced a stroke more than six months earlier were included in this study. METHODS: Subjects in both the experimental group (n = 12) and the control group (n = 10) participated in a conventional rehabilitation program involving a 60-minute session five days per week for a period of four weeks. Subjects in the experimental group additionally practiced VFT 30-minute sessions, five days per week, for a period of four weeks. RESULTS: After the intervention, the experimental group showed significantly improved static sitting balance ability (leftright, anteriorposterior moment, and velocity moment), and dynamic sitting balance ability (anteriorlateral moment). In visual perception tests, motor free visual perception test (MVPT) scores showed a significant increase of approximately 17% in the experimental group after the intervention. CONCLUSION: The results of this study demonstrate the effectiveness of VFT in enhancing body function, as evidenced by improved sitting balance and visual perception of chronic stroke patients.
