Outline of Final Research Achievements

The purpose of this study was to develop a biofeedback system using wearable sensors for gait training. The changes of trunk fluctuation in patients with knee osteoarthritis, and the validity of measurement of leg extension angle in health subjects were analyzed. The effect of the leg extension angle on gait in healthy older people was also investigated. Previous study have stated the leg extension angle is related to the propulsion force during late stance. In addition, present results showed that the leg extension angle is related to the knee flexion angle during swing phase. Therefore, biofeedback of the leg extension angle during gait might alter the gait kinematics throughout waling cycle.

Academic Significance and Societal Importance of the Research Achievements

脳卒中治療ガイドライン2015では,関節角度などを用いたバイオフィードバック療法の推奨度はグレードBとされている。しかし,実際の臨床現場でバイオフィードバック療法が用いられることは極めて少ない。この背景には,バイオフィードバック療法に用いられる機器の利便性の低さ等が挙げられる。ウェアラブルセンサーは簡便に歩行を測定可能であり,バイオフィードバックにも利用可能と考えられる。本研究の結果は,ウェアラブルセンサーによるフィードバックを利用した汎用性の高い歩行トレーニングの基礎的情報として意義が大きい。
