Why do doctors use VNG machines to evaluate vestibular disorders?https://medicaledgesolutions.com/vng-machine/ ?

Doctors use VNG testing equipment to evaluate how well the inner ear and brain are managing balance and eye movement. This non-invasive test helps identify the root cause of dizziness, vertigo, or balance disorders—whether the issue comes from the inner ear (peripheral) or the brain (central). During a VNG test, small cameras record eye movements while the patient follows visual targets or experiences mild changes in position. These results give doctors precise data to diagnose vestibular disorders and create more effective treatment plans. VNG technology has become a key diagnostic tool for ENT specialists, neurologists, and balance clinics because it provides objective, accurate insights that other tests can’t always capture.
