Effects of visual perturbation on the gait variability during different locomotion speeds

Temporal and spatial gait variability is relatively small in the healthy walking pattern. Patients with a sensory loss show a pathological increase of gait variability. The purpose of this study was to investigate the influence of artificially disturbed visual locomotion control on the gait variability during different locomotion speeds. Nine healthy subjects (31.0±8.4 years, 2 females) participated in the study. For each subject the walking pattern was recorded while walking under normal conditions and while walking under visual perturbation (VP). Therefor, subjects were artificially blinded with light-impenetr…
