ウエアラブルセンサーによるランニングの逆動力学解析

（地面反力を測定しない解析方法の構築）

抄録

In this study, an inverse dynamics analysis method 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 estimate the contact period between the foot and ground was constructed by using the vertical acceleration data of the body. Moreover, the method to identify the ground reaction force was constructed, i.e., the top down approach. 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.
