What happens during a balance test?
During a balance test, also known as a vestibular function test, an audiologist assesses the function of the vestibular system, which contributes to balance and spatial orientation. One common test is the videonystagmography (VNG), where the individual wears infrared goggles while performing a series of eye and head movements. These movements help evaluate eye movements in response to various stimuli, such as changes in head position or exposure to visual targets. Another test, the caloric test, involves introducing warm or cool air into the ear canal to stimulate the inner ear and observe eye movements. The results provide valuable information about the function of the vestibular system, aiding in the diagnosis and treatment of conditions related to balance disorders. The tests are painless and conducted in a controlled environment within an audiology clinic by trained professionals.
