Electronystagmography test for dizziness is a test used to evaluate people with vertigo, a false sense of spinning or motion in your eyes that can cause dizziness. The test measures the movements of your eyes and how well the cranial nerves within your brain are functioning.
Electronystagmography (ENG) can detect nystagmus, involuntary rapid eye movements that occur in response to various stimuli.
ENG evaluates how well the cranial nerves within your brain are functioning. The two cranial nerves are the acoustic nerve and the oculomotor nerve. The acoustic nerve connects the brain to the inner ear while the oculomotor nerve connects the brain to the muscles of your eyes. These nerves control your eye movements, hearing, and balance.
