Vestibular, Rehabilitation
Latest version View entry history
Definition
The vestibuloocular reflex (VOR) has been created with an amazing plasticity that counters the inevitable forces of disease and aging that barrage the reflex. In fact, this plasticity prevents us from suffering significant functional impairments – namely, gaze and gait instability. One example of the critical and extreme plasticity within the VOR includes complete reversal of the VOR when fit with lenses that demand it. The three primary functions of the peripheral vestibular system are (1) stabilizing visual images on the fovea of the retina during head movement to allow clear vision; (2) maintaining postural stability, especially during movement of the head; and (3) providing information used for spatial orientation. The purpose of this article is to outline how vestibular rehabilitation must incorporate head rotation in order to improve gaze and gait instability due to a deficient VOR.
