Abstract

本研究では,対麻偉者のリハビリテーション支援を目的として,足漕ぎ車椅子のための簡易かつ実用的なFES制御系の開発を進めている.これまでに,市販の足漕ぎ車椅子(Profhand,TESS)に対して簡易なFES制御システムを構築し,有効な被刺激筋を決定したが,随意走行時と比較した場合に,走行速度が低く,不安定であるといった問題点があった.本報告では,筋の電気刺激に対する反応性に着目し,走行速度と被験者毎の反応時間を考慮した刺激タイミングを提案した.健常者において,以前の固定刺激タイミングとの比較実験を行なった結果,全ての被験者において速度上昇,速度の安定化が確認された.

This study aimed at developing cycling wheelchair rehabilitation system using FES, which is compact and easy to use at clinical site. We developed a simple FES control system that did not need extensive modification of the wheelchair using a wireless inertial sensor and wireless electrical stimulators and appropriate muscles for FES cycling were found. However, cycling speeds of FES cycling were slower and less stable than voluntary cycling. In this report, a method of determination of stimulation timing considering the cycling speed and the muscle reaction time was proposed and tested. It was shown that the cycling speed was raised and became stable.
