The vertical computerized rotational head impulse test. [PDF]

J Vestib Res
The computerized rotational head impulse test (crHIT) uses a computer-controlled rotational chair to deliver whole-body rotational impulses to assess the semicircular canals. The crHIT has only been described for horizontal head plane rotations. The purpose of this study was to describe the crHIT for vertical head plane rotations.

Caloric and video head impulse test dissociated results in dizzy patients

Frontiers in Neurology, 2022
IntroductionWe are now able to detect abnormalities for any semicircular canal with the use of the video head impulse test (vHIT). Prior to the vHIT, the gold standard for unilateral canal paresis of the lateral canal was considered the caloric test ...
