Abstract
By easily stimulating the ear with loud sound and recording on tonically contracted neck muscles, vestibular evoked myogenic potential (VEMP) testing can reflect inner ear function other than the cochlea and semicircular canal. This expands the test battery for clinicians to explore saccular disease, adding a potential usefulness to the saccular sternocleidomastoid myogenic reflex. The ideal stimulation pattern for tone evoking VEMPs is as follows: frequency 500 Hz, stimulation repetition rate 5 Hz; rise/fall time 1 ms; and plateau 2 ms. This review shows a clinical application of VEMP in both peripheral and central vestibular disorders.
