Abstract
Stabilizing the visual surroundings of human subjects influences postural control during perturbations of their equilibrium. The latency of the 1st EMG [electromyography] burst is increased and its amplitude is reduced. Body pitch is 36% stronger than with normal vision. Eye closure does not produce any significant modification of muscular responses and postural performance. This result explains why vision is not considered a rapid source of postural reaction. Eye closure cannot be considered visual deprivation.
