The Elderly Fall Risk Assessment and Prediction Based on Gait Analysis

In this paper, a cell phone and a three dimension accelerometer are used to develop a simple fall risk prediction system. Accelerometer offers a practical and low cost method of objectively monitoring human walking. This paper gives the gait stability and gait symmetry definition only under the data conditions of acceleration. According to the gait model, the stability and symmetry of gait are analyzed and calculated, at last not only the individual´s gait can be evaluated, but it also constituted a gait assessment model. The proposed gait assessment model can be used to predict the fall risk of walking subject. The experiment results show that this method achieved better performance of prediction and efficiency.
