Rotary Chair Testing
Diagnosing Dizziness and Delivering Data-Driven Results
The purpose of rotary chair testing is to determine if your inner ear or your neurological system is the cause of your balance disorder. Every head movement in one direction has a corresponding eye movement in the opposite direction. The rotary chair measures these movements to help determine your diagnosis. At Southern New Hampshire Vertigo & Balance Center, we are proud to be one of only a handful of clinics in New England to offer rotary chair testing.
Rotary chair testing is a mid-frequency test of vestibular function, testing a range of different frequencies from 0.01 Hz to 0.64 Hz. Rotary chair (head) speed is compared to eye movement speed to assess the vestibulo-ocular reflex (VOR).
