Analysis on Degree of Symmetry in Both Legs with Walking Motion using a Compact Radar Sensor

Abstract

For this article, we analyze degree of symmetry in both legs with walking motion of an individual by using a compact continuous waveform Doppler radar. Generally, time-varying Doppler frequencies of both legs in a spectrogram includes two main parameters such as step length and radial upper leg length. Thus, the degree of symmetry in both legs can be presented as a function consisting of main parameters, so it can lead to efficient non-contact walking motion examination of patients undergoing rehabilitation training. In experiments, the degree of symmetry in both legs of an individual was efficiently analyzed from several walking motions. © 2024 IEEE.
