VNG Pre-Test

INSTRUCTIONS

This test is designed to help locate the source of dizziness or balance disorders. You will either wear video goggles or have electrodes taped to your face to measure eye movements. The test consists of three parts. First, you will be asked to watch a series of lights on a light bar. Next, you will be asked to lie in different positions. Finally, your ears will be irrigated with warm and cool air to measure back and forth eye movements called nystagmus. Your ears will need to be free of wax. The test will take approximately 1.5 to 2 hours. Due to the amount of time scheduled for this test, please notify us prior to your test date if you are unable to keep your appointment. Failure to notify will result in a “no show” fee of $50. These tests are not painful. However, you may feel dizzy after the test, so we ask that you arrange for someone to drive you home after the testing is completed.
