Frequently Asked Questions

What should I do to prepare for the Rotary Chair Test?

Before you take the balance test, stop using Xanax, Valium, and Dramamine because they can interfere with your balance. You should avoid dietary supplements for 24 to 48 hours before the test, but it’s important to talk to your doctor about it first. The day of your test, make sure not to consume caffeine, alcohol, or tobacco. It’s important not to wear heavy eye makeup, since this could disturb the eye-tracking on the headset. You should wear clothing that is comfortable and loose, and your healthcare team might tell you to fast for a couple of hours before you have the test.

You will be asked to sit on a chair that moves as you are in a room without any light. You will have electronic goggles fitted with infrared cameras so that your eye tracking can be recorded. In the beginning, you will be guided by lights shown on a screen with your eyes. After that, the chair will slowly turn to check how easily your eyes can follow the motion. This allows doctors to understand the way your brain and ear sensors support your balance.

A slight feeling of imbalance may last after the test, but it usually disappears fast. It takes your eyes some minutes to adjust to brightness after being in the dark. Tiredness or getting a headache can happen to some people, especially if they regularly get migraines. It’s better to have a friend or family member drive you home in case you become a bit unsteady. The majority of people are able to go back to their usual activities after they feel better.

The test measures your eye movements as the chair rotates, providing insight into how your body maintains balance. Doctors analyze the direction, speed, and quality of your eye movements to detect any issues. This information helps them diagnose the problem and decide the best way to support your recovery.

Should the test confirm a balance disorder, the doctor may advise you to do vestibular rehabilitation exercises to correct the issue. There are times when doctors recommend medicines to ease dizziness or nausea. The type and extent of your condition will determine the treatment plan given to you for the best care.
