The video Head Impulse Test (vHIT) is one of the most advanced vestibular diagnostic tests now available in Dhaka. At Vertigo & Balance Center, vHIT helps our specialists objectively measure how well your vestibulo-ocular reflex (VOR) is working — a key step in diagnosing the cause of vertigo, dizziness, and balance disorders. If you’re searching for a reliable vHIT test in Dhaka, this page explains exactly what the test involves and what it can reveal about your vestibular health.

The video Head Impulse Test (vHIT) is a modern, objective vestibular function test used to assess the function of the semicircular canals and the vestibulo-ocular reflex (VOR). The test evaluates how effectively the eyes maintain visual fixation during rapid, passive head movements.
vHIT allows assessment of all six semicircular canals individually and provides real-time, quantitative information about vestibular function. It is widely used in the evaluation of vertigo, dizziness, imbalance, and gaze instability — making it a core diagnostic tool at our vertigo center in Dhaka.
The vHIT is performed to:
Unlike traditional tests, vHIT evaluates vestibular function under physiological head movement conditions — giving doctors a real-world picture of how your balance system responds.
vHIT is commonly recommended for patients with:
Vestibular neuritis
Unilateral or bilateral vestibular hypofunction
Peripheral vestibular disorders
Unexplained dizziness with suspected inner-ear cause
Yes. The vHIT is a safe, non-invasive, and radiation-free test. Head movements are brief and stay within normal physiological range. The test can be stopped immediately if you feel any discomfort.
The patient wears lightweight video goggles A visual target is fixed at eye level The examiner delivers small, rapid, unpredictable head impulses Eye and head movements are recorded simultaneously Each semicircular canal is tested separately The test is brief, non-invasive, and well tolerated by most patients — no needles, no radiation, no downtime.
vHIT primarily evaluates: VOR Gain (ratio of eye velocity to head velocity) Presence of overt saccades (visible after head movement) Presence of covert saccades (hidden during head movement) Canal-specific vestibular performance These parameters give your doctor objective, measurable evidence of vestibular function or dysfunction — rather than relying on symptoms alone.
Normal vHIT : VOR gain within accepted limits and absence of pathological saccades.
Abnormal vHIT : Reduced VOR gain with corrective saccades.
Reduced gain in one canal suggests unilateral vestibular hypofunction
Reduced gain in multiple canals suggests bilateral vestibular involvement
Normal vHIT with persistent symptoms may indicate central or otolith-related disorders
No. vHIT is completely non-invasive and painless. Patients wear lightweight goggles while the examiner performs brief, gentle head movements.
The test itself typically takes just a few minutes per side, though the full appointment including setup and calibration may take longer.
The vHIT (Video Head Impulse Test) cost in Dhaka usually ranges from ৳2,000 to ৳5,000, depending on the diagnostic center, equipment, and specialist consultation. For the exact price, it is best to contact the clinic or diagnostic center before booking the test.
vHIT identifies whether your semicircular canals and VOR are functioning normally. It’s one part of a full vestibular workup — your specialist will combine it with your history and other tests to reach a diagnosis.
vHIT should always be performed and interpreted by a trained vestibular professional, since results need clinical correlation.
