Balance Tests
Reviewed
Balance tests are a group of tests that check for balance disorders, such as vertigo or unsteadiness. They help find the cause of balance problems so you can get the right treatment and avoid falls. Common tests include electronystagmography (ENG), videonystagmography (VNG), rotary chair test, posturography, VEMP, and Dix-Hallpike maneuver. Some tests may cause temporary dizziness or nausea.
Preparation and collection
Wear loose, comfortable clothes. Depending on the specific test, you may be asked to avoid certain foods or medicines before testing. Do not stop any medicine without talking to your provider first. You may want to arrange for someone to drive you home if dizziness lasts longer.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- Some tests may cause temporary dizziness or nausea that usually resolves in a few minutes.
- Results should be interpreted by a healthcare professional; there is no single reference interval or unit provided by the source.
- Balance disorders can be difficult to diagnose, and multiple tests may be needed.
What to do next
If your results indicate a possible balance disorder, your provider may order additional tests or start treatment. Treatment depends on the type of disorder, such as the Epley maneuver for BPPV, diet and lifestyle changes for Meniere's disease, or balance retraining therapy. Discuss follow-up with your healthcare professional.
