Cervical Vestibular Evoked Myogenic Potential (cVEMP) Test

What is a cVEMP test?

A cVEMP test is an objective test used to assess part of the balance (vestibular) system. The test measures the electromagnetic potentials generated from muscles across the neck in response to sound stimulation. 

What should I expect during a VEMP test?

During this test:

• Sticker electrodes are placed on the neck, forehead, and chest, and these areas are gently cleansed beforehand.
• Sound stimuli is presented to the patient through earphones, while the patient is lifting and tilting the head in order to create tension in the neck muscles.
• The electrodes record muscle activity that occurs in response to the sound.
• Once the measurements are collected, the electrodes and earphones will be removed, and the patient can proceed with the day as usual.
• The results are interpreted by the audiologist. 

How do I prepare for a cVEMP test?

• Do not wear lotion or makeup on the neck, face, or chest.
• Please inform your audiologist or physician if you are taking any muscle relaxants or if you have a pacemaker or defibrillator, as these may affect the recordings.
• During the test, you will be asked to periodically and briefly raise and tilt your head in order to create tension in the neck.

When will the test results be ready?

After the test, the audiologist will interpret the data and write the report. The report will be reviewed by your physician and a follow-up appointment with your physician is typically scheduled with the physician at least five days after the test.
