What is a Vestibular Evoked Myogenic Potential (VEMP) Test?
A VEMP (Vestibular Evoked Myogenic Potential) test is used to evaluate how well certain parts of the inner ear and balance system are functioning. It measures the body’s reflex response to sound stimuli, helping assess the vestibular (balance) organs and related nerve pathways.
The test is non-invasive and involves placing small sensors on the skin to record muscle responses triggered by sound.
Who needs a cVEMP test?
A cVEMP test is recommended for individuals experiencing dizziness, vertigo, imbalance, or suspected inner ear disorders. It is often used when doctors want to assess specific parts of the vestibular system in more detail.
How is a cVEMP test performed?
During the test, small electrodes are placed on your neck and near your collarbone. You will be asked to turn or lift your head to activate your neck muscles while sounds are played through earphones. The muscle responses are then recorded and analyzed.
Is the cVEMP test painful?
No, the test is painless. You may feel slight discomfort from maintaining a head position or from the sound stimulation, but it is generally well tolerated.
What do cVEMP results indicate?
The results help determine whether the saccule and the inferior vestibular nerve are functioning properly. Abnormal results may indicate vestibular disorders or nerve pathway issues.
