Mode Analyses on the Kinematical Structure of Basic Movements and Residual Patterns in Human Locomotion using Motion Capture Data

摘要

This article treats mode analysis of kinematic structure of human locomotion. We investigated human locomotion using singular value decomposition. From motion-captured data of human locomotion, we extracted common basic movements and residual modes, and analyzed kinematical structures. The results show that there are basic movements commonly observed for all participants in usual walk. On the other hand, higher modes in knee-constrained walk represent different control strategies depending on the physical property of the legs. These residual modes involve personal peculiarities or symptoms of motor dysfunction in locomotion.
