Abstract

The purpose of this study was to verify the utility of a simple motion analysis system which we made by partially observing actual movement in a clinical setting and demonstrating the objectivity of the data thus obtained. In this system, angular velocity sensors were put on the right and left acromion of the subjects to measure the movement of each during free walking. The gait cycle was determined using plantar pressure sensors. The subjects of the measurement were healthy persons and hemiplegic cases, and the characteristics of their gait were comparatively analyzed. As a result, we could objectively obtain gait data from healthy subjects which showed few differences between the right and left sides and from hemiplegic cases which showed individual characteristic acromial movements. Consequently, this gait analysis method was considered to be clinically applicable as an objective gait analysis method.<br>
