Repeated optokinetic stimulation in conditions of active standing facilitates recovery from vestibular deficits.

abstract：:The purpose of this study was to establish whether visual motion parallax participates in the control of postural sway. Body sway was measured in ten normal subjects by photoelectric recordings of head movements and by force-plate posturography. Subjects viewed a visual display ("background"), which briefly moved (2 s...
