Abstract

The purpose of this study was to investigate the effect of different instructions on the weight shift task and the partial weight bearing task. Thirty-nine participants asked to keep 2/3 of their own body weight on their right leg and 1/3 of their own body weight on their left leg while standing. One group started with two-leg standing at the beginning and the other group started with one-leg (right) standing. Then, each group was asked to put 2/3 of their body weight on their right leg and the 1/3 of it on their left leg. Participants practiced 18 trials with 4 opportunities to receive knowledge of the result (KR), followed by 3 no-KR retention trials 5 minutes later and 24 hours later. The performance was superior when subjects were instructed to put more weight on a leg than when they were asked to reduce it. Therefore, in the practice of partial weight bearing, giving a proper instruction for the direction of the load is more effective than one for the participant's weight. It was also apparent that some of the participants practiced this task with their own strategy.<br>
