External perturbations can challenge a person’s walking stability, and people will autonomously make a series of responses to regain the balance of walking, which includes two periods: perturbation-perception (reaction time, RT) and posture-adjustment (motion time, MT). The purpose of this paper was to investigate the correlations between the dynamic walking stability and perception-motor abilities. During the 30 level walking trials preformed by sixteen healthy participants, perturbations were applied at random. The fall probability (FP) during the walking with perturbations was calculated to evaluate the dynamic walking stability of each participant. Furthermore, the ground reaction force (GRF) of each participant during walking with perturbations was recorded and analyzed. The experimental results show that the RT had a significant positive-correlation with FP, while MT had no correlation with FP.
