Rotary chair testing involves having electrodes placed around your eyes to measure your eye movement while the chair you are sitting in moves back and forth at varying speeds. Eye movements can give the doctor insight into the health of your balance system. The testing takes place within an enclosed dark booth with an infrared camera pointing toward your eyes so the tester can monitor your eye movement throughout testing. Although this test does not test each ear separately, it does give the doctor more information on how your vestibular system operates over a wider portion of its operating range. (Total test time is approximately one hour.)
To get accurate results there are a number of medications that should be discontinued 48 hours prior to testing. These include pain pills (with codeine), sleeping pills, cold or allergy pills, antihistamines, tranquilizers,
anti-nausea pills, sedatives, alcohol, and anti-dizziness pills. If you have any questions about your medications, please consult your referring physician or family doctor.
If nausea is common with your balance problem, avoid eating for two hours prior to your appointment. The total test time is approximately one hour and cannot be interrupted during that time. Please take this into account when making parking arrangements. If your balance problem interferes with driving, it would be advisable for you to have a companion with you.
