Abstract

In human gait motion analysis, which is one useful method for efficient physical rehabilitation to define various quantitative evaluation indices, joint angles and joint loads are measured during gait. Recently, it is thought that trans-femoral amputees with the prosthetic limb must regain motion pattern by refined rehabilitation program using joint moments as a representative joint loads and understanding them is indispensable for biomechanical consideration. On the other hand, human keeps a high correlation among the motion of all joints during gait. Joint motion analysis of the correlation extracts a few simultaneously activating segmental coordination patterns, and the structure of the intersegmental coordination is attracting attention to an expected relationship with a control strategy. However, when the evaluation method using singular value decomposition has been applied to only joint angles of the lower limb, joint moments related to the rotational motion of the joints have not yet been considered. In this paper, a novel quantitative analysis method concerning rotational motion of lower limb joints by using joint moments as well as joint angles aims to be proposed. Each parameter of the healthy subject and trans-femoral amputee is measured by using mobile force plate and attitude sensor, split-belt treadmill simultaneously and their motion patterns are analyzed by the proposed method. As a result of the experiments, patterns of each evaluation index are obtained as the remarkably different feature quantities between healthy subject and trans-femoral amputee especially pertaining to joint moments. Finally, the effectiveness of the quantitative analysis concerning human motion is validated.
