The videonystagmograph diagnostic test is used to evaluate which of the following?

The videonystagmograph (VNG) diagnostic test is specifically designed to assess a person's balance by measuring the function of the vestibular system, which controls balance and eye movements. This test utilizes video technology to track eye movements in response to various stimuli, providing crucial information about how well the inner ear and brain are working together to maintain stability and orientation. By focusing on balance, VNG helps identify issues related to vertigo, dizziness, and other balance disorders, making it an essential tool in the evaluation of vestibular function.
