At the Balance Disorders Clinic, evaluation of the inner ear typically lasts about two hours and involves a variety of technically advanced tests that may include the following: 

• The Gans Sensory Organization Performance Test (GSOP) works in conjunction with other test methods to determine the pattern of the patient’s disequilibrium and appropriate treatment options. 
• Videonystagmography (VNG) comprises a series of subtests using video goggles to assess the inner ear and central motor functions. 
• Rotational Chair testing is the most sensitive test to determine vestibular (inner ear) pathology and is the “gold standard” for diagnosis of bilateral vestibular loss.  
• Vestibular Evoked Myogenic Potentials (VEMP) determine if organs in the inner ear and the vestibular nerve pathway are intact and working properly.
• Auditory Brainstem Response (ABR) determines how well your acoustic nerve transmits the signal representing sound from the inner ear to the brain.

After the initial evaluation, treatment will either be performed in the clinic or further recommendations will be sent back to your referring physician in a written report.
