A specialized diagnostic test used to evaluate dizziness, vertigo, and balance disorders by analyzing inner ear and eye movement function.
Videonystagmography (VNG) is a diagnostic test that evaluates balance problems and dizziness by measuring involuntary eye movements (nystagmus).
Because the inner ear and brain work together to control balance and eye motion, abnormal eye movements can indicate whether symptoms originate from the vestibular system (inner ear) or the central nervous system.
During VNG testing, infrared video goggles record eye movements while different positional and stimulation tests are performed.
Recurring dizziness or imbalance without a clear cause may require vestibular evaluation.
If you feel as though the room is spinning, VNG helps determine whether the inner ear is involved.
Difficulty walking straight, frequent falls, or instability may indicate vestibular dysfunction.
Persistent motion sensitivity or nausea triggered by head movements may be linked to balance disorders.
During the procedure:
The test may briefly reproduce dizziness symptoms, but this is temporary and helps identify the underlying cause.
If you are experiencing dizziness, vertigo, or balance instability, VNG testing at NdxLabs can help identify the cause and guide the right treatment plan.
