Vestibular Evoked Myogenic Potentials (VEMP)

Vestibular Evoked Myogenic Potentials (VEMP) is a test which examines your balance system. The vestibular system is responsible for helping you keep your balance and is located in your inner ears. Your vestibular system has connections to your neck muscles and lets your neck muscles know when your head has moved. During the test, two sensors are placed on your neck and a third is placed on your forehead. While you turn your head and contract your neck muscles, a loud sound is placed in your ear. The loud sound stimulates part of your vestibular system, and the sensors on your neck pick up the vestibular system’s response. The test results will give your doctor more information about the health of your vestibular system. (The test time is approximately one hour.)

To get accurate results there are a number of medications that should be discontinued 48 hours prior to testing. These include pain pills (with codeine), sleeping pills, cold or allergy pills, antihistamines, tranquilizers,
anti-nausea pills, sedatives, alcohol and anti-dizziness pills. If you have any questions about your medications, please consult your referring physician or family doctor.
