The Conventional Head Impulse Test Versus the Suppression Head Impulse Test: A Clinical Comparative Study [PDF]

Journal of International Advanced Otology, 2023
BACKGROUND: The suppression head impulse test is a new paradigm of the head impulse test, recently introduced for clinical use. The aim of this study was to assess the importance of the suppression head impulse paradigm in evaluating vestibular function. METHODS: This comparative study was conducted from June 2020 to June 2022.

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.

Binocular video head impulse test: Normative data study [PDF]

Frontiers in Neurology, 2023
IntroductionThe video head impulse test (vHIT) evaluates the vestibulo-ocular reflex (VOR). It’s usually recorded from only one eye. Newer vHIT devices allow a binocular quantification of the VOR.Purpose (Aim)To investigate the advantages of ...

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.

Video head impulse test in bilateral vestibulopathy

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: Bilateral vestibulopathy is a rare chronic condition with multiple etiologies. Bilateral vestibulopathy is characterized mainly by unsteadiness when walking or standing, which worsens in darkness, as well as oscillopsia.

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

False-positive head-impulse test in cerebellar ataxia [PDF]

Frontiers in Neurology, 2012
:The objective of this study was to compare the findings of the bedside head impulse test (HIT), passive head rotation gain, and caloric irrigation in patients with cerebellar ataxia (CA).

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 ...

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.

Bilateral Vestibulopathy: What Can the Video Head Impulse Test Tell Us? [PDF]

Audiology Research
Bilateral vestibulopathy (BV) is a known cause of chronic vestibular syndrome. With the video head impulse test (VHIT), we can now evaluate all six semicircular canals independently and establish BV subgroups based on canal gain patterns.
