Being unable to maintain your balance can be disorienting and may make you feel faint, dizzy, lightheaded, or as though you’re spinning. Dizziness and issues of balance can be the result of an underlying condition such as vertigo, Meniere’s disease, migraines, or head trauma.
How Balance Testing is Performed
There are a few types of balance tests available, but the most widely used is a videonystagmography (VNG). Because balance relies on the function of the inner ear, this test measures eye movements to evaluate the inner ear and motor functions. The VNG test is also used to look for vestibular disorders and pinpoint where the ear is affected. The test takes place in several parts:
- Part one uses specialized glasses that are designed to record your eye movements. You will be seated in a dark room, and dots will begin to appear. The provider will ask you to follow the dots with your eyes.
- In the second part, your provider will move your head or other areas of your body for evaluation.
- The final step of the test uses water of varying temperatures that is poured into the ears to see the reactions.
