| Abstract(in English) | The walking rhythm of the human is known to show phase-shift or "resetting" in response to external perturbations applied to the lower limb. During the response transient changes of the motion trajectory, so called stumbling reaction, are observed. It is believed that such responses correct the perturbed motion and prevent the walker from falling. The aim of this study is to elucidate the relation between such rhythm resetting and dynamic stability of walking. To this end, we utilized a dynamical system model of human walking and analyzed its behavior numerically. The model had the stable limit cycle corresponding to the steady walking. We depicted its basin of attraction. The walker fell down under some conditions of perturbations, however, the appropriate phase resetting could prevent the walker from falling. |
