Video Head Impulse Testing: From Bench to Bedside
Seminars in Neurology, 2020AbstractOver 30 years ago, the head impulse test (HIT) was measured with search coil recordings and it provided robust evidence for a new test of vestibular function that could detect impairment of a single semicircular canal, that is, the lateral canal.

Video head impulse test – „očni EKG“ [Video head impulse test – eye] [PDF]
, 2017 In the diagnosis of acute vestibular syndrome (AVS) the key part is a quick and reliable differentiation between peripheral and central etiologies. Video head impulse test (vHIT) is a new method that is based on the examination of rotational vestibulo-ocular reflex. vHIT has demonstrated high specificity for peripheral vestibular damage.

Video head impulse test and seasickness susceptibility
Experimental Brain ResearchSeasickness can have a devastating effect on a crewmember's well-being. In the literature, there is a controversy about whether car sickness could be diagnosed by vestibular evaluation tests, specifically by Video Head impulse test (vHIT) a semi-circular canal (SCC) function test.

[THE VIDEO HEAD IMPULSE TEST (VHIT)].
Harefuah, 2023The video head impulse test (vHIT) is a new tool in the vestibular tests' arsenal. It is based on the clinical Head Impulse Test, where the integrity of the vestibulo-ocular reflex is tested by high frequency excitation of the semi-circular canals. The vHIT system is composed of an accelerometer measuring the head movements, and a high frequency infra ...

Clinical experience with video Head Impulse Test in children
International Journal of Pediatric Otorhinolaryngology, 2015A standardized diagnostic protocol for children's vestibular assessment is still missing in daily clinical life. As rotatory chair testing and caloric test are usually not tolerated well by children, the aim of our study was not only to evaluate the importance and practicability of the video head impulse test performed in children with and without ...

Video head impulse testing (VHIT) in the pediatric population
International Journal of Pediatric Otorhinolaryngology, 2015VHIT is the first vestibular test to evaluate all six semicircular canals. This test has advantages over the rotary chair and caloric tests in evaluating children since it does not require fear-inducing darkness or provocation of dizziness. The goal of this study was to review our initial experience with VHIT in children and adolescents at a pediatric ...

Acute vestibular syndrome: clinical head impulse test versus video head impulse test
Journal of Neurology, 2018HINTS battery involving head impulse test (HIT), nystagmus, and test of skew is the critical bedside examination to differentiate acute unilateral peripheral vestibulopathy from posterior circulation stroke (PCS) in acute vestibular syndrome (AVS). The highest sensitivity component of the battery has been reported to be the horizontal HIT, whereas skew

The Video Head Impulse Test (vHIT)
2019The video head impulse test (vHIT) is presently an essential part of the laboratory vestibular examination for patients with a suspected acute or chronic vestibular disorder. This chapter reviews its neurophysiology, interpretation, and clinical applications. A comparison with the caloric tests is included.

Video Head Impulse Test Diagnoses Vestibulotoxicity
Otolaryngology–Head and Neck Surgery, 2012ObjectiveVideo oculography is a simple, accurate alternative to the scleral search coil method measuring individual semicircular canal function in Head Impulse Testing (HIT). Here we compare the video HIT with the caloric test for the diagnosis of unilateral or bilateral vestibulotoxicity due to systemic gentamicin therapy.MethodUsing the video HIT ...

Reducing the number of impulses in video head impulse testing – It's the quality not the numbers
International Journal of Pediatric Otorhinolaryngology, 2019The video-Head-Impulse-Test (vHIT) is widely used to evaluate vestibular function. Nevertheless, there is no consensus on the necessary or ideal number of impulses performed for robust VOR gains. Therefore, the aim of our study is to analyze how many impulses are needed to receive reliable VOR gains in difficult testing situations like testing children
