The purpose of this study was to reveal the relationship between stooped angles of upper body segments and lower joint moments during sit-to-stand movement. We evaluated joint moments by using the support moment which was advocated by Winter. There was the relationship between the stooped angle of trunk and lower joint moments. When support moment became maximal value, the percentage of hip joint moment in support moment was high corresponding to trunk angles. At the same time, the percentage of the knee joint moment in support moment was low. There was, however, no correlation between the pelvis angle and lower joint moments. It was, therefore, suggested that lower joint moment made up for each other by adjusting trunk angle.
