Here are some of the different balance diagnostic testing services we offer at the Hearing & Balance Center:
Electronystagmography (ENG), Videonystagmography (VNG)
VNG/ENG testing allows measurement of eye movements related to dizziness. It is the most common vestibular (inner ear) test performed at our center and provides documentation of the function of the inner ear, eye movements, and related neural pathways.
Computerized Dynamic Posturography (CDP)
CDP was developed to evaluate an individual's ability to use sensory cues from the inner ear (vestibular), eyes (vision), and muscles and joints (somatosensory) to maintain balance and stability.
CDP is a non-invasive procedure using sensors and computer monitoring to record body movement while the patient maintains balance in a variety of standing test conditions. It helps to determine a patient's fall risk, appropriate timing of balance responses and in what environments a patient will have difficulty.
Evoked potentials including Auditory Brainstem Response (ABR), Electocochleography (ECochG), Vestibular Evoked Myogenic Potentials (VEMP), and Electoneuronography (ENOG)
Evoked potentials require placing electrodes on the skin to measure changes in nerve, muscle, or chemical activity in the body as sounds or other stimuli are used. This testing provides diagnostic information for various hearing and balance disorders.
Rotational Vestibular Chair Testing (RVT)
Use of the rotary chair at the Hearing and Balance Center is unique to only a small number of facilities in the state. This test greatly increases our ability to detect subtle vestibular (inner ear) abnormalities and vestibular healing. The testing is performed by spinning in a rotary chair at various speeds. It also allows for vestibular assessment of all ages.
Positional vertigo testing and treatment procedures
There are many causes of vertigo, dizziness and/or loss of balance. One of the most common of these is Positional Vertigo. Benign Paroxysmal Positional Vertigo (BPPV) is often discovered with diagnostic testing. People with this disorder complain of dizziness or spinning when they look up or down, bend over, lie down, get up from lying down, or when turning their head or body from side to side.
The dizziness or vertigo is generally brief, lasting less than one minute, but it can be very strong and can cause disorientation, nausea and disequilibrium.
BPPV has a number of known causes, including head injury, but sometimes just occurs spontaneously. The good news about this significant disorder is that it is very treatable. Our research shows that 93 percent of patients with BPPV can be cleared with one or two treatment sessions.
