The purpose of this study was to investigate the effect of perception-action coupling exercise on posture balance in the elderly. The subjects(n=42) were assigned to 2 groups: perception-action coupling exercise(PACE) group(n=20, 68.00±4.50 yrs) and general exercise(GE) group(n=22, 67.33±4.85 yrs). The subjects were asked to participate in perception-action coupling's exercise program or general exercise program(3 times/week, 80min/day) for 12 weeks. The subjects were tested on static posture balance(eyes open and close) and dynamic posture balance(anterior and posterior) at the beginning and the end of the 12-weeks program. For data analysis, total root mean square values were calulated and independent t-tests and 2 way-ANOVA were used. After 2 different exercise programs for 12 weeks, both groups did not show any change on static posture balance. But PACE group was better than GE program group on dynamic posture control ability. Therefore, this study may suggest that exercise program based on perception-action coupling improves posture balance in the elderly, and further becomes an effective way that prevents from falling.
