ワイヤレスモーションセンサーによるランニングの逆動力学解析

（遊脚の動きを考慮した解析）

抄録

In this study, an inverse dynamics analysis method considering swing leg motion was constructed only by using some wireless motion sensors.(WMS) First, it was confirmed that the acceleration data by the WMS agreed well with the one by the 3-dimensional motion analysis system. Then, the method to separate the hip joint reaction force obtained from the equation of motion of the body into the support leg and the swing leg and to identify the ground reaction force was constructed, i.e., the top down approach considering swing leg motion. For the actual running data, the ground reaction force was identified, and it was concluded that the result agreed well with the one by using the force plate. The method constructed in this study, therefore, is concluded to be applicable for the actual application.
