Gait Analysis Based on Gait Acceleration

Yi Liu

Abstract

This paper introduces a portable system which is used to measure gait cycle parameters and analysis gait symmetry.A three-axis accelerometer(MMA7260) is used to capture the acceleration signal of gait,and gait parameters could be calculated by an autocorrelation procedure.By analysis the ratio of correlation coefficient between signal step and gait cycle,gait symmetry could be estimated.
