Definition & Meaning of "Electronystagmography"

What is "electronystagmography"?

Electronystagmography (ENG) is a test used to measure and record involuntary eye movements, known as nystagmus, to help diagnose balance disorders and problems related to the inner ear. During the test, small sensors called electrodes are placed around the eyes to identify and record these eye movements while the patient follows specific visual triggers or undergoes head movements. ENG helps identify issues with the vestibular system, which controls balance, and can be useful in diagnosing conditions like vertigo or dizziness.
