What is VNG testing?

Purpose:

VNG is used to evaluate the vestibular system, which is responsible for balance, motion, and spatial orientation.

How it works:

During a VNG test, you wear special goggles with infrared cameras that record your eye movements.

Stimuli:

The test involves various components, including:

Caloric testing:

Warm and cool air or water is introduced into the ear canal to stimulate the inner ear.

Ocular-motor testing:

Your ability to focus and move your eyes accurately is assessed.

Positional testing:

You are placed in various positions to provoke specific eye movements.

Diagnosis:

VNG can help identify the cause of vertigo, disequilibrium, and dizziness, and determine if a vestibular disorder is present.

Conditions Diagnosed:

VNG testing can help diagnose various vestibular and neurological conditions, including: Benign paroxysmal positional vertigo (BPPV), Meniere's disease, Labyrinthitis, Vestibular neuritis, Multiple sclerosis (MS), Brain tumors, Traumatic brain injury (TBI) and Stroke (cerebrovascular accident). Why is VNG testing important?

Objective assessment:

VNG provides an objective assessment of vestibular function, which can be helpful in determining the cause of balance problems.

Treatment guidance:

The results of VNG testing can guide healthcare professionals in developing effective treatment strategies.

Monitoring progression:

VNG can also be used to monitor the progression of vestibular disease and the response to therapeutic interventions
