Abstract

Passive power-assist supporter
We are developing a passive power assist supporter called Smart Suit Lite. Smart Suit Lite, a compact, lightweight device, uses the force of elastic belts both to support muscles and to stabilize the torso in a way similar to the corset. It is reported that the corset stabilizes posture, and decreases intradiscal pressure by applying pressure around the pelvis. The mechanism behind this remains to be fully elucidated, however, and has not been used actively for power assist devices. This study aims to construct a mechanical model of trunk stabilization generated by assistive devices. In this paper, we propose modeling based on basic experiments measuring motions under static conditions.
