Motion analysis for prevention of falling during human sit-to-stand motion

Abstract

The standing movements of elderly people and people with motor disabilities are generally associated with a high risk of falling. We measured and analyzed the angle of the human lower-limb joints during standing motion using an optical motion tracking system. From the results, we found that there is a coordination mechanism between the lower-limb joints. Moreover, we retrieved that the movement mode of standing up motion can be categorized into two types, which are "switching" rather than "transition."
