Influence of absent visual feedback and head position on temporal gait variability. The magnitude of temporal gait variability during walking with eyes closed (absent visual feedback) (A) and walking with extension of the head (B) depends on the height stimulus. The coefficient of variation of stride time is significantly increased in the balcony situation. ^*indicates p < 0.05. Black, bold lines indicate the medians of the coefficient of variation of stride time [%] for all vHI subjects (black thin lines represent the 0.95 confidence interval).
