The effects of visual feedback training on sitting balance ability and visual perception of patients with chronic stroke.

[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 (left∙right, anterior∙posterior moment, and velocity moment), and dynamic sitting balance ability (anterior∙lateral 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.
