The video head impulse test (VHIT) is widely used to identify semicircular canal function impairments in adults. But classical VHIT testing systems attach goggles tightly to the head, which is not tolerated by infants. Remote video detection of head and eye movements resolves this issue and, here, we report VHIT protocols and normative values for children. Vestibulo-ocular reflex (VOR) gain was...

Introduction: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all six canals in patients definitively d...

HYPOTHESIS As the anterior and posterior semicircular canals are vital to the regulation of gaze stability, particularly during locomotion or vehicular travel, we tested whether the high-velocity vestibulo-ocular reflex (VOR) of the three ipsilesional semicircular canals elicited by the modified Head Impulse Test would correlate with subjective dizziness or vertigo scores after vestibular neuri...

<p><strong>Background:</strong> This study aimed to determine the test-retest reliability of computerized rotational head impulse test (crHIT) as an additional clinical tool assess horizontal semi-circular canal (HSCC) function in pediatric population.</p><p><strong>Methods: </strong>To re-test crHIT, included 29 normally developing children with a mean...

A 48-year-old man presented with vertigo, unsteadiness, nausea, and vomiting that developed subacutely when he was at work. Hearing was preserved. Apart from left displacement during the Fukuda stepping test, nothing relevant was found through neurologic examination (see video on the Neurology Web site at www.neurology.org). Head impulse test (HIT) was positive on the left side. Asymmetry of th...
