Vestibular / Balance Testing

  The Vestibular Autorotation Test (VAT) is used to assess the vestibuloocular
  reflex (VOR). The VOR is a system that helps us visually track objects while we
  are moving our head and/or body. The VAT allows us to look at the speed and
  timing of the VOR to determine if the system is working correctly. When the VOR
  is not working correctly, vision can be distorted and balance is affected. VOR
  abnormalities are often the cause of dizziness when all other systems are working
  correctly. This test takes about 30 minutes including preparation time.

  Computerized Platform Testing is used to assess the three primary sensory
  contributions to our balance: inner ear, eyes, and sense of touch. This test
  addresses balance on both stable and unstable surfaces, as well as in both static
  and dynamic visual environments. This test takes approximately 15 minutes.

  Electronystagmography (ENG) is a series of tests performed to assess activity
  of the inner ear and the pathways to higher areas in the brain. This test is divided
  into several categories: Ocular Motor testing consists of tracking a series of
  lights; Positional/Positioning testing puts the patient in a series of different
  positions to elicit any abnormal responses; and Biothermal Caloric Irrigations,
  which involves putting both cold and warm air in each ear and measuring the
  response of each inner ear for comparison. This test take approximately 1 hour
  including preparation time.
