The vestibular system is a portion of the inner ear which is contributes to movement and the sense of balance. It can be damaged due to injury (such as head trauma) or disease (such as a viral infection). The brain is unable to rely on the vestibular system for accurate information and this can result in dizziness, vertigo and loss of balance. The most common vestibular problem which people seek physical therapy for is BBPV (benign paroxysmal positional vertigo).
A physical therapist performs a thorough evaluation to ascertain the reason for dizziness and or loss of balance and uses this information to devise a vestibular rehabilitation program which is a combination of manual therapy techniques, exercise and patient education.
