We often take our balance for granted, until there’s a problem.

Your sensory information about motion, equilibrium, and spatial orientation is provided by the vestibular apparatus that lives in each of your ears.

When the vestibular organs on both sides of your head are functioning properly, they send symmetrical impulses to the brain – but when they are not, this can cause dizziness and balance problems.

If you have any concerns about dizziness, then we can help through a number of advanced tests including being one of just four balance centers in Arizona to have the state-of-the-art Computerized Rotary Chair.

Balance and vestibular testing

Hearing and balance are interrelated, as both are controlled within the inner ear. If you are experiencing balance difficulties, vertigo, and/or disequilibrium, our audiologists will work closely with our ENT doctors to pinpoint the cause and best treatment options.

We provide hallmark diagnostic testing for dizzy and gait challenged patients, such as electrocochelography (ECochG), auditory brainstem response (ABR), videonystagmography (VNG), computerized dynamic posturography (CDP), and computerized rotational chair testing.


This advanced test allows us to determine whether or not dizziness may be due to a disorder of the inner ear or brain, and particularly to determine whether or not both inner ears are impaired at the same time.

During testing, you will sit in a motorized chair that swivels side-to-side at a controlled rate. From this test, we’re able to test three things. The chair test measures your dizziness, the optokinetic test measures dizziness caused by the viewing of moving stripes, and the fixation test measures nystagmus while you’re being rotated.

We are one of just four balance centers in the entire state of Arizona that offers this advanced form of testing.

Computerized Dynamic Posturography

This advanced non-invasive specialized clinical assessment evaluates how well you are able to use your inner ears, eyes, and the body’s muscle and joints in order to maintain your balance.

During CDP testing, you will stand on a force-sensing support surface, within a moveable visual surround. These tests will determine how well you can maintain your balance under different conditions, designed to determine the source of your balance problems.
