The Video Head Impulse Test [PDF]
Frontiers in Neurology, 2017 In 1988, we introduced impulsive testing of semicircular canal (SCC) function measured with scleral search coils and showed that it could accurately and reliably detect impaired function even of a single lateral canal.

Video head impulse test in vestibular migraine
Brazilian Journal of Otorhinolaryngology, 2021 Introduction: Vestibular migraine as an entity was described in 1999 and its pathophysiology is still not established. Simultaneously with research to better understand vestibular migraine, there has been an improvement in vestibular function assessment.

Suppression Head Impulse Test (SHIMP) versus Head Impulse Test (HIMP) When Diagnosing Bilateral Vestibulopathy. [PDF]
J Clin Med, 2022 The Suppression Head Impulse (SHIMP) test was introduced as an alternative to the Head Impulse Paradigm (HIMP) to overcome challenges in VOR gain calculation due to the interference of covert saccades. The objectives of this study were (1) to determine if SHIMP, compared to HIMP, reduces covert saccades in BV patients and (2) to define the agreement on

The Turkish Journal of Ear Nose and Throat, 2022 Objective: The Video Head Impulse Test (V-HIT) is a non-invasive diagnostic test that evaluates the functions of the semicircular canals separately. This test records eye movements in response to head movements, and the vestibulo-ocular reflex gain (VOR ...

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 ...
