VGN Testing at Ohio Injury Doctors

VNG Testing (Videonystagmography) – Balance & Concussion Diagnostic Study

We offer VNG (Videonystagmography) testing, an advanced, objective, digital, and dynamic balance study designed to diagnose:

  • mTBI (mild Traumatic Brain Injury) / Concussion

  • Vestibulopathy (inner ear dysfunction)

  • Canalithiasis or Cupulothiasis (floating or adhered crystals in the semicircular canals)

When is VNG Testing Used?

VNG is a powerful tool to identify neurological and vestibular damage caused by:

  • Motor vehicle accidents

  • Sports injuries

  • Workplace injuries

  • Falls or sudden head/neck movements

Importantly, a head does not need to make contact with any surface for a concussion to occur. Injuries like coup-contrecoup, hyperextension/hyperflexion, or violent side-to-side head motion (common in car crashes or whiplash) can all cause significant trauma—even without visible impact. In cases with no direct head contact but with concussion symptoms, the diagnosis of “unspecified head injury” is clinically appropriate.

Symptoms That May Indicate the Need for VNG Testing

You may be experiencing one or more of the following symptoms—sometimes from multiple overlapping conditions like mTBI and vestibulopathy at once:

  • Dizziness or vertigo

  • Falls or near-falls (catching yourself on walls or furniture)

  • Loss of balance

  • Motion sickness

  • Gait changes due to visual disturbances or fear of falling

  • Headaches

  • Tinnitus (ringing in the ears)

If you have even one of these symptoms, especially following a recent injury, VNG testing is strongly recommended to accurately diagnose the cause and rule out or confirm serious underlying conditions.

Why It Matters for Medical and Legal Recovery

VNG testing doesn’t just guide your treatment—it also provides objective evidence that can help:

  • Support a concussion diagnosis even in the absence of head impact

  • Establish the mechanism of injury for accurate medical records

  • Ensure appropriate approval for testing through Workers’ Compensation

  • Strengthen personal injury or workplace injury claims by showing a clear link between the accident and your symptoms

Proper initial documentation and thorough history—including how the injury occurred—is essential for both your medical and legal outcomes.
