Research on lift assistance seat for elderly people—focusing on analysis of motion capture and EMG

Abstract

We observed their movement by measuring their range of motion using a motion capture to investigate behavior in sitting. In addition, we performed electromyographic analysis of joints to examine the causes of the burden in sitting down and standing up. We believe that the slower movement in sitting down and standing up in the elderly compared to those in young people was caused by loss of muscle strength and joint weakness. Therefore, we came to a conclusion that something supplementing those strengths is required. To improve the elderly’s trajectory of sitting down and standing up to the level of young people, a force supporting from the bottom is needed.
