What is vestibular testing?
Vestibular testing is a series of diagnostic evaluations designed to assess the function of the vestibular system, which contributes to balance and spatial orientation. These tests help identify issues related to the inner ear and the brain's processing of sensory information that controls balance. Common vestibular tests include videonystagmography (VNG), electronystagmography (ENG), and rotary chair testing, which assess eye movements in response to specific stimuli to evaluate the function of the vestibular organs. Posturography measures postural stability, and caloric testing involves stimulating the inner ear with warm or cold air or water to provoke eye movements. Vestibular testing is often conducted by audiologists or specialized healthcare professionals to diagnose conditions such as vestibular disorders, Meniere's disease, or benign paroxysmal positional vertigo (BPPV) and to determine appropriate treatment plans.
