Methods for Detecting the Patient's Pupils' Coordinates and Head Rotation Angle for the Video Head Impulse Test (vHIT), Applicable for the Diagnosis of Vestibular Neuritis and Pre-Stroke Conditions

De Computis
In the contemporary era, dizziness is a prevalent ailment among patients. It can be caused by either vestibular neuritis or a stroke. Given the lack of diagnostic utility of instrumental methods in acute isolated vertigo, the differentiation of ...

Vestibular semicircular canal function as detected by video Head Impulse Test (vHIT) is essentially unchanged in people with Parkinson’s disease compared to healthy controls

Journal of Vestibular Research-Equilibrium & Orientation, 2021
BACKGROUND: Parkinson’s disease (PD) is a common multi-system neurodegenerative disorder with possible vestibular system dysfunction, but prior vestibular function test findings are equivocal. OBJECTIVE: To report and compare vestibulo-ocular reflex (VOR)

The characteristics of vHIT gain and PR score in peripheral vestibular disorders

Acta Oto-Laryngologica, 2020
Background Clinical application of vHIT is limited due to a lack of interpretation of vHIT gain and saccades. Objectives This research focuses on comparing common vertigo diseases on vHIT gain and saccade divergence(PR score).

Normative values for semicircular canal function with the video head impulse test (vHIT) in healthy adolescents

Acta Oto-Laryngologica, 2020
Background The vHIT device, which has a mechanism based on measuring the VOR gain, helps us to quickly evaluate six semicircular canals. Aims/Objectives The aim of this study was to establish normative values for semicircular canal function with the ...

Binocular vHIT in Healthy Participants: An Optimized Strategy

The Laryngoscope
The objectives of this study were to observe the differences between the left and right eyes in healthy individuals during binocular video head impulse testing (vHIT) and to identify the optimal eye for a more precise evaluation of the vestibulo‐ocular ...

Comparison of computerized rotational impulse test (crHIT) and video head impulse test (vHIT) in all semicircular canals among normal subjects

Journal of Vestibular Research-Equilibrium & Orientation
Background The computerized rotational head impulse test (crHIT) employs whole-body impulsive rotations like the angular motion used in the video head impulse test (vHIT) to assess the function of all semicircular canals (SCCs).

Transmastoid superior semicircular canal dehiscence plugging: VHIT findings.

Acta Oto-Laryngologica
BACKGROUND Superior canal dehiscence syndrome (Minor's syndrome) is a condition characterized by a bony defect in the superior semicircular canal (SSCC), with treatment primarily being surgical, notably through plugging of SSCC.
