Rehabilitation of balance-impaired stroke patients through audio-visual biofeedback

Abstract

This study explored how audio-visual biofeedback influences physical balance of seven balance-impaired stroke patients, between 33–70 years-ofage. The setup included a bespoke balance board and a music rhythm game. The procedure was designed as follows: (1) a control group who performed a balance training exercise without any technological input, (2) a visual biofeedback group, performing via visual input, and (3) an audio-visual biofeedback group, performing via audio and visual input. Results retrieved from comparisons between the data sets (2) and (3) suggested superior postural stability between test sessions for (2). Regarding the data set (1), the testers were less motivated to perform training exercises although their performance was superior to (2) and (3). Conclusions are that the audio component motivated patients to train although the physical performance was decreased.
