モーションキャプチャーと筋骨格モデル解析ソフトウェアを用いた内骨格型パワーアシストスーツによる持ち上げ動作の解析

抄録

In this study, the motion while lifting a heavy object under wearing an endoskeleton-type power assist suit was captured by motion capture device, and the burdens on the lower back were analyzed using the musculoskeletal modeling software AnyBody Modeling System. Then, the muscle activity of the erector spinae muscles, and disc compression force and disc shear force between L4/L5 lumbar vertebrae in the state of no assist force, the state of wearing passive power assist suit and the state of wearing active power assist suit, were evaluated and compared. As a result, effectiveness of the power assist suit on reducing the burden on the lumbar region was verified. In addition, the assist effects of the passive power assist suit and the active power assist suit were almost equivalent.
