Vestibular Rehabilitation: How It Treats Dizziness & Balance Disorders

The Vestibular System and Balance

The vestibular system (inner ear) provides critical information about head position and movement to the brain. When damaged, the result is dizziness, unsteadiness, visual disturbance with head movement, and profound impairment of daily function.

Mechanisms of Vestibular Rehabilitation

Vestibular compensation: the brain learns to use other sensory inputs (vision, proprioception) to substitute for damaged vestibular function. Habituation: repeated exposure to provocative movements reduces the sensitivity of the dizzy response. Sensory reweighting: learning to appropriately prioritize different balance inputs.

Gaze Stabilization Exercises

VOR (Vestibulo-Ocular Reflex) exercises involve moving the head while maintaining visual focus on a target. This retrains the connection between head movement sensing and eye stabilization — the most common deficit after vestibular nerve damage.

Balance Retraining

Progressive challenge of the balance system by removing visual cues (eyes closed), using unstable surfaces (foam), and combining head movements with postural challenges forces the brain to develop robust compensatory strategies.
