Abstract: The purpose of this study was to examine the practice effect of the body sway under three conditions ; eyes closed, eyes open, and feedback condition. The feedback information was only locus of Y-component of the body sway drawn on a X-Y recorder. The subjects were instructed to control their posture as well as possible by watching the pen and their loci of Y-component. That was the feedback condition. The number of trials in each condition was twenty-five. The indexes were velocity, acceleration, shift length, and area of the body sway. The results were as follows : (1) The acceleration of anterior-posterior component had the practice effect under the feedback condition. (2) The velocity, the acceleration, and the shift length of lateral component under the feedback condition were the smallest of the three conditions. The area of the body sway under the feedback condition was the smallest of the three conditions. (3) Females had larger velocity, acceleration, shift length, and area of the body sway than males under the three conditions. These results suggested that when the subjects controlled their posture by the feedback information used in this study, the lateral component of the body sway became more stable.
