Vestibular function tests are clinical techniques used to evaluate part of the vestibular system. Stimulation of the inner ear results in specific eye movement termed nystagmus, which are integral in the evaluation of the vestibular system. Nystagmus has a fast-phase and a slow-phase component and is named based on the fast phase. Electronystagmography (ENG), videonystagmography (VNG), and rotation testing measure nystagmus to provide objective assessment of the function of the vestibular system.
