Vestibular Autorotation TestVATplus - Vestibular Autorotation Test

The Vestibular Autorotation Test (VAT) is an 18-second test (performed six times) of the high frequency horizontal and vertical VOR's for diagnosis, treatment planning, and monitoring of vestibular disease. Testing with the VAT often identifies problems not found with other vestibular tests, because the VAT tests natural, faster motions, and unlike other conventional vestibular tests, evaluates both the horizontal and vertical canals.
