Effectiveness of sole-floor reaction force measurement in a supporting equipment for human stand-up movement

Abstract

The aging of Japan is currently still going on, and senior citizen households have a tendency to increase. stand-up movement, which is one of daily motions, is a heavy burden on elderly people whose muscular strength tends to decline. Therefore, we aim to develop " a supporting equipment for human stand-up movement" targeted at elderly people who can live independently to support the stand-up movement in order to reduce the burden in daily life, and conduct research toward practical application. In our laboratory, a movable handrail type stand-up movement measuring equipment has been produced experimentally. we analyze the stand-up movement of the user and examine the evaluation method of the support effect from the measured values of the sensors installed in this measuring equipment. In this paper, we focus on the change of the sole-floor reaction force and verify the effectiveness of the support effect on the evaluation.
