Pretest Instructions for VNG

Welcome to the Rehder Balance and Hearing Clinic. Our clinic is an affiliate of the American Institute of Balance, which specializes in and is dedicated to patients with dizziness and/or balance disorders.

Your Time at Our Clinic

A comprehensive battery of tests will be performed during the appointment time allocated for you. Prior to each test an explanation will be given so that you will have a better understanding of what is being tested and why. We make every attempt to make your visit comfortable as well as educational.

Once your evaluation is complete each part is carefully evaluated and reviewed. This process is as important as your test, so please understand that your test results will not be discussed with you in detail at the time of your evaluation. Once the interpretation has been made, a detailed report will be forwarded to your referring physician.
