Analysis of impulse response on walking stability by a synchronized system of two accelerometers

摘要

A useful analyzer system has been developed for walking stability. It is composed of two sub-systems. One acquires time series data of joints movements using a newly developed, synchronized system of two accelerometers (SSA). Another is a system of analyzing the persons walking stability. It utilizes the impulse response by Auto Regressive (AR) modeling. The impulse response of movement factors enables analysis of their dynamic relations. The biofeedback control analysis of walking stability using this analyzer system suggests new potential for the understanding of medical recovery and kinesitherapy in rehabilitation and physical fitness in daily movement.
