Analysis of the effect of fatigue on walking gait stability

Abstract

Effect of fatigue on the stability of normal walking is studied in this paper. A 3D accelerometer sensor was used to measure the accelerations of center of gravity of a walking person. Variability of acceleration in lateral, vertical and anterior/posterior directions was used as an index to assess the walking stability. We observed decreases in walking stability in lateral, vertical and anterior/posterior directions after fatigue.
