The balance system is a complex one involving coordination of the vestibular (inner ear), visual (eyes), and the sensory nerves throughout the body. The ENG (electronystagmography) is one method utilized to evaluate problems with balance and equilibrium.

Test Description: The ENG is a battery of tests utilized to diagnose your problem. You will have electrodes placed near your eyes to monitor your eye movements. The first of these tests involves rapid side to side eye movements and following moving targets with your eyes. You will then be moved into different positions to test for dizziness caused by movement or motion. Lastly, a Caloric evaluation will be completed. Caloric testing involves introducing warm and cool water into the ear canal to stimulate a response of the inner ear system. The resulting eye movements are then measured. Patients often feel some movement or turning during Calorics and may feel dizzy. They may not feel different at all. Either response is not uncommon and does not mean anything good or bad about the results. If patients feel movement it is temporary and related to the change in temperature from the caloric irrigation.

Test Duration: 1 to _ hours
