Balance Testing

With such a wide range of hearing and balance disorders, many of which have similar symptoms, it’s important for an ear, nose, and throat specialist to make an accurate diagnosis in order to come up with a successful treatment plan. Diagnostic testing plays an important role in determining the condition responsible for a patient’s suffering.

Types of Testing

VNG testing uses a combination of video goggles and infrared cameras to measure involuntary eye movements, called nystagmus. Neural connections extend from the balance mechanism in the inner ear to the muscles of the eye. Rapid eye movements, which can only be captured using high-tech equipment, can indicate a disorder of the balance system. During a VNG test you are given a series of visual tasks and the camera records your eye movements.


There are generally four parts to VNG testing. In addition to evaluating rapid eye movements, a tracking test measures eye movements as they follow a visual target, a positional test measures dizziness in relation to different head positions, and a caloric test evaluates responses to warm and cold water introduced through a tube in the ear canal. Testing is non-invasive and usually lasts between 60 and 90 minutes. There may be episodes of brief dizziness and some minor discomfort from the goggles, but otherwise you’re unlikely to experience side effects.

Electronystagmography (ENG)
This test measures eye movements in order to assess the functioning of the vestibular system, which is responsible for balance.

Otoacoustic Emissions (OAE)
This test measures the response of hair cells in the inner ear when stimulated and can indicate the presence of a conductive or cochlear hearing loss.

This balance test measures the effectiveness of the somatosensory system, vestibular system, and vision to determine which area(s) to focus on when treating a balance disorder.

This test measures eye movements to evaluate the inner ear and central motor functions. It can determine whether a vestibular disorder is the cause of a balance problem, and where one or both ears are affected.

These diagnostic tests are quick, painless, and can help us diagnose and evaluate a variety of hearing and balance disorders. Call Acadian Hearing & Balance Center at (337) 237-0716 for more information or to schedule an appointment.
