How are vestibular disorders diagnosed?
Because the vestibular system is in close proximity to the hearing apparatus, vestibular testing includes hearing tests. Eye movements often hold clues to vestibular dysfunction. To record eye movements, a technique called electronystagmography (ENG) is used. In ENG testing, electrodes are put on the facial muscles that control eye movement. The patient is then placed in a variety of situations, and the eye movements are electronically recorded. Balance is an essential component of vestibular functioning. During Balance testing, patients may be asked to stand on special platforms that record the movement of the body. This kind of testing is called moving platform posturography (Vestibular Disorders Association).
