That is, the patient does not turn his or her head themselves, rather the examiner moves the head.5/5(). Purpose. The Head Impulse Test (HIT) is a widely used clinical assessment technique used to assess the angular vestibulo-ocular reflex (aVOR). Specifically, the HIT assesses horizontal semicircular canal (HSCC) and superior vestibular nerve function in response to discrete, small amplitude (~10), high acceleration (~ s2) rotational head impulses. The head impulse test (HIT), or head thrust test, is used to help identify an impaired vestibulo-ocular reflex (VOR) in patients with vertigo, particularly in suspected acute peripheral vestibulopathy.() The examiner briskly rotates the patient’s head while having the patient fixate on a target, usually the examiner’s nose.
