The VEMP examination is used to measure whether certain vestibular system components and associated nerves functioning normally. Responses in this test are measured from various muscles in the neck and around the eyes. The VEMP test utilizes skin surface electrodes and headphones (or earphones). During the test, the sound is presented for a few seconds through the headphones, the vestibular organs are stimulated and activate muscle responses, and the mounted electrodes record the responses.
