What is Vestibular Testing?
A vestibular test is a series of tests that evaluate the balance and function of the inner ear. Testing the vestibular system function may start with an overall assessment, gathering information on the client’s symptoms, medical history, etc. They may have to undergo further , such as the following:
Electronystagmography (ENG) or Videonystamography (VNG).
- Purpose: Check one’s eye movement in various settings
- Equipment used: ENG uses small electrodes near the eyes, while VNG uses an infrared camera.
Rotary Chair Test
- Purpose: Check for inner ear and brain disorders or response to head movements needed for daily activities.
- Equipment used: Electrodes near the eyes and a moving computerized chair.
Computerized Dynamic Visual Acuity Test (DVA)
- Purpose: Checks brain compensation for a client’s possible vestibular issues and how it affects their daily activities.
- Equipment used: Monitor with letters or a printed-out Snellen Chart.
Computerized Dynamic Posturography (CDP)
- Purpose: Checks the function of three sensory inputs - vestibular, somatosensory, and vision - used to maintain one’s center of gravity.
- Equipment used: Sensors, moving walls, and a moving platform.
Aside from the four mentioned above, other vestibular tests a client may undergo are the Subjective Visual Vertical Test, VEMP, VHIT, SVV, and SVH.
