In this paper, we have studied the effect of fatigue on walking gait during normal walking. Acceleration of COG in lateral, vertical and anterior/posterior directions were recorded and analyzed to study the effect of the fatigue. Increase in cadence and shortening of step length were observed after the fatigue. The results also showed an increase in the RMS value of acceleration in lateral direction affecting the lateral stability during walking. The variability analysis showed that the amplitude variability is increased in lateral, vertical and anterior/posterior directions after fatigue which can be related to the weakness of the lower extremity muscles. Frequency analysis revealed that higher frequency components in the acceleration increased due to the fatigue. An increase in the wavelet entropy after fatigue showed the increase in the disorder in the vertical and anterior/posterior accelerations.
