Abstract

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); the other is a system for analyzing the person´s walking stability. It utilizes the impulse response by autoregressive (AR) modeling. The impulse response of movement factors enables the 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
