Introduction: The Vestibular Evoked Myogenic Potential (VEMP) is a test that evaluates the lesions in the encephalic trunk that compromise the vestibule-spinal route, such as in the cases of multiple sclerosis (MS). The acoustic stimulus in VEMP is evoked in the form of clicks from hearing phones. The macula is activated by sounds stimulus, generating an electric potential that follows by the way of the inferior vestibular nerve, lateral vestibular nucleus, vestibule-spinal tract, and finally ipsilateral motor neuron of the cervical musculature. The evoked myogenic answer is captured with superficial electrodes in the sternocleidomastoid muscle. Among the few diagnostic examinations for the evaluation of the vestibule-spinal route, the VEMP is considered an important method.
