The Video Head Impulse Test
Video head impulse testing, an instrumented expansion of the bedside head impulse test using video eye tracking and quantification of eye and head movement, is a relatively new objective measure of dynamic semicircular canal function. This article provides an overview of both the bedside and video head impulse tests. The anatomical and physiological bases of the test are briefly reviewed, along with test administration and response characteristics in healthy individuals and patients with vestibular loss. Literature examining the use of the video head impulse test in several common vestibular disorders, in children, and in patients with acute vestibular syndrome is summarized.
