A dizziness test, more accurately described as a vestibular test, is a group of procedures used to diagnose the cause of dizziness, vertigo (a sensation of spinning), and balance problems. These tests evaluate different parts of your balance system, which includes your inner ear, brain, and eyes. Several types of tests exist, each focusing on a specific aspect of balance.
Types of Dizziness Tests
-
Videonystagmography (VNG): This test records eye movements to detect problems in your inner ear's balance system. VNG is used to find out if you have a disorder of the vestibular system (the balance system in your inner ear). It can also help find problems.
-
Electronystagmography (ENG): Similar to VNG, ENG uses electrodes to measure eye movements associated with vertigo or dizziness. Electronystagmography (ENG or electrooculography) is used to evaluate people with vertigo (a false sense of spinning or motion that can cause dizziness).
-
Vestibular Evoked Myogenic Potentials (VEMP) Test: This computerized test measures a specific part of the vestibular system linked to dizziness. You'll lie down or sit upright during the test, with electrodes placed on your shoulders, forehead, and neck. The VEMP is a computerized test used to measure part of the vestibular (balance) system that may be related to dizziness.
-
Rotational Chair Testing: This test uses a rotating chair to assess your body's response to spinning, helping diagnose certain types of dizziness.
-
Dix-Hallpike Maneuver: This is a specific procedure used to diagnose benign paroxysmal positional vertigo (BPPV), a common cause of dizziness triggered by head movement. This test consists of a series of two maneuvers.
-
Other Tests: Depending on the suspected cause of dizziness, additional tests like hearing tests, MRI scans, and neurological examinations may be performed. Your healthcare provider may order vestibular testing if you have symptoms of dizziness, vertigo or…
Why Are Dizziness Tests Necessary?
Dizziness can stem from various conditions, from inner ear infections to neurological problems. Accurate diagnosis is crucial for effective treatment. These tests help pinpoint the underlying cause of your dizziness, enabling your doctor to provide appropriate care. Our ENT specialists use the latest technologies to test the different systems of your body and brain to find out what's causing your unsteadiness.
