Effects of Device on Video Head Impulse Test (vHIT) Gain [PDF]

Journal of the American Academy of Audiology, 2017
Background:Numerous video head impulse test (vHIT) devices are available commercially; however, gain is not calculated uniformly. An evaluation of these devices/algorithms in healthy controls and patients with vestibular loss is necessary for comparing and synthesizing work that utilizes different devices and gain calculations.Purpose:Using three ...

Video head impulse test (vHIT) in migraine dizziness

Journal of Otology, 2018
Migraine is an extremely prevalent primary headache disorder that frequently associates parallel symptoms such as dizziness, tinnitus and hearing loss. Our aim is to investigate differences in video head impulse (vHIT) results with patients suffering from vestibular migraine (VM) and healthy people, taking into consideration mean values of vestibule ...
