Abstract
A wearable sensor system for gait analysis is presented, which is composed of a combination of a six-axis ground reaction force sensor system with parallel mechanism and motion sensor modules using by gyroscope sensor and accelerometer. From output of the sensors, joint moment of the lower limb is estimated by applying inverse kinetics. Experimental study is carried out to evaluate accuracy of the proposed estimation system. Experimental results of the proposed system compare well with those of the conventional method which is a combination of 3D camera system and force plate.
