Change of gait pattern according to type of perpendicular vision and speed

Abstract

Walking speed and the field of view is clinical element of gait. Previous studies saw mainly visual feedback effects. The purpose of this study was to see the change of gait pattern according to speed and the kinds of vision which are fixed vertically. This study recruited healthy 15-male and 16-female. The subjects walked 3 minute on the treadmill in 5km, 3km, and 1km each session. The vision of subjects fixed the front, the bottom and the top. Gait pattern (step length, stride length, speed, and cadence) collected using OPTOGait. The date was analyzed by one-way ANOVA. There were significant differences in the gait pattern of speed (p < 0.05). However, there are no significant difference in the sight which is fixed vertically (p > 0.05). Gait speed was related to the stability associated with falls. Because of decreasing step length, stride length and cadence. Slow speed gait was helpful to prevent from fall-down, and useful to control to posture control. In normal subjects, the vision will be considered as not affecting the gait pattern.
