A study on accuracy improvement of gait parameter estimation using wearable force plates

Abstract

This paper deals with the estimation of gait velocity and distance by the velocity compensation using adaptive Kalman filter. This method compensates gait velocity by using the velocities calculated by forward time integration and backward time integration. We conducted the measurement experiment the 5m gait test and the 10m gait test. The motion capture was used to the experiment in the 5m gait test. The results for gait distance in the 5m gait test indicated the results by proposed method is corresponding to that by the motion capture. Furthermore, the proposed method indicated the effective results in the 10m gait test. This method can be used for the gait analysis using the wearable force plates.
