VideoNystagmography (VNG)

Our Audiology department features the most state of the art hearing and vestibular testing equipment available. The vestibular disorders laboratory features the next generation of videonystagmography to accurately diagnose and treat balance disorders. Vestibular rehabilitation physical therapy is available on site.

A videoonystagmogram (VNG) measures normal eye movement and involuntary rapid eye movements called nystagmus. It also checks the muscles that control eye movements. ENG checks how well the eyes, inner ears, and brain help you keep your balance and position (such as when you change from lying down to standing).

ENG is done to determine whether there is a problem in how the inner ear, brain, or nerves connecting them function. These problems may cause dizziness, vertigo or loss of balance.

Nystagmus occurs normally when the head is moved. However, nystagmus without moving your head or nystagmus that does not go away may be caused by conditions that affect the inner ear, brain, or the nerves connecting them.

During ENG the movements are recorded on graph paper. A series of recordings is done.

Baseline recordings are taken with your head at rest.

How To Prepare
For 2 to 5 days before the test, you will be asked to stop taking:

Your doctor may ask you to eat a light meal or not eat for 3 to 4 hours before the test, because the test can cause nausea and vomiting.

Do not wear facial makeup during the test so the electrodes can attach to the skin.

If you normally wear glasses, contact lens, or hearing aids, bring them to the test.

If you have a neck or back problem, tell your doctor, so your neck and back will be protected during the test.
