Unlocking the Cause of Dizziness & Vertigo: What is ENG Testing?

Ever experienced a sudden spinning sensation, unsteadiness, or frequent dizziness? You might be dealing with Vertigo—a common condition often linked to inner ear issues.

To pinpoint the exact cause, specialists perform an ENG Test (Electronystagmography). Here is how it works:

What is an ENG Test? An ENG test evaluates the function of your acoustic nerve (the nerve responsible for hearing and balance) and your inner ear balance system. It works by tracking eye movements in response to different positions, visual stimuli, or temperature changes (caloric stimulation).

What Happens During the Test? Goggles or Electrodes: Specialized goggles (or small sensors) are placed around the eyes to measure involuntary eye movements (nystagmus).

Positional Testing: The patient lies down, changing head or body positions so the clinician can observe how the inner ear responds.

Caloric Testing: Gentle warm or cool air/water is introduced into the ear canal to check reflex responses in each ear independently.

Why Is It Important? 🎯 Accurate Diagnosis: Helps determine whether dizziness stems from the inner ear (peripheral) or the brain (central).

🩺 Targeted Treatment: Allows audiologists and doctors to design effective, tailored rehabilitation plans.

🌿 Safe & Non-Invasive: Performed comfortably in a controlled clinical environment under trained supervision.
