(VNG) Test

Vestibular assessment

The VHIT is an instrumented bedside technique used to diagnose a reduction in vestibular function in one ear compared to the other. An examiner abruptly accelerates and then decelerates the head, moving the head in rapidly at high speed and then stopping it.

What is a vertigo test?

Vertigo causes and treats dizziness. The sense of dizziness or spinning. It is a false sensation of movement. The person feels like he is spinning or that the world around him is spinning. It is caused by a problem with the inner ear, brain, or sensory nerve path. Vertigo can occur at any age, but usually it happens in people aged 65 and older.

What causes vertigo?

  • 01

    Vestibular Neuronitis

    This condition occurs due to viral infections causing inflammation in the vestibular nerve, resulting in vestibular neuronitis.

  • 02


    It is an inflammation in the vestibulocochlear nerve, which is responsible for encoding the body's position, motion, sound, and inner ear labyrinths. Inflammation is usually caused by viral infections.

  • 03

    Meniere’s Disease

    It is the formation of fluid in the inner ear that leads to tinnitus (ringing in the ear) and hearing loss, triggering vertigo attacks.

  • 04


    It is the abnormal growth of skin in the middle ear as a result of chronic infections. The accelerated growth causes ear damage, which results in hearing loss and dizziness.

  • 05


    Benign paroxysmal positional vertigo occurs when calcium carbonate crystals develop in the inner ear canal. This leads the individual to lose their sense of balance. BBPV is more common in older adults and can happen for no apparent reason.

Balance therapy

It is commonly recommended to people with condition vestibular neuritis. It physical therapy which makes your motion system less sensitive to motion. It is also called as vestibular rehabilitation.
