Vestibular Evoked Myogenic Potential

Vestibular Evoked Myogenic Potential (VEMP) evaluates portions of the vestibular system that the VNG cannot test. This test evaluates the vestibular system by looking at the contractions of neck muscles. During the testing the patient is asked to lift their head and turn away from a beeping sound. This stimulates the muscles needed to measure the response. To measure the response small sticker electrodes are placed on the face and neck. The electrodes do not administer any shocks; they pick up the electricity given by the muscles as they move.
