title: Different step-over movement strategies for disturbance stimulations.
abstract: This study examined differences in performance when 10 healthy adult participants took steps under three different disturbance stimulations (with opened and closed eyes and with the use of light), with and without an obstacle present. In the voluntary condition, participants recognized the obstacle beforehand and stepped over it quickly; in the light condition, participants recognized the obstacle beforehand and quickly stepped over it after light stimulation; in the closed eyes condition, participants did not recognize the obstacle beforehand, but after opening their eyes when hearing a sound, they quickly stepped over the obstacle. The swing time of the gait was significantly longer in obstacle conditions for all stimulations. The swing time was significantly longer under the closed eyes condition than the light and voluntary conditions. The clearances were significantly higher in order of the closed eyes, light, and voluntary conditions in the presence of an obstacle.
