Video head impulse testing: Pitfalls in neurological patients

Journal of the Neurological Sciences, 2022
The video head impulse test (vHIT) assesses the vestibulo-ocular reflex (VOR) during a rapid high-velocity low amplitude (10°-20°) head rotation. Patients with peripheral vestibulopathy have a reduced VOR gain with corrective catch-up saccades during the head turn. There are several pitfalls, mainly technical, which may interfere with interpretation of

Tracking Motor Progression and Device‐Aided Therapy Eligibility in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterise the progression of motor symptoms and identify eligibility for device‐aided therapies in Parkinson's disease, using both the 5‐2‐1 criteria and a refined clinical definition, while examining differences across genetic subgroups.

Video head impulse test – „očni EKG“ [Video head impulse test – eye]

Liječnički vjesnik, 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.

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)

Functional testing of the vestibular ocular reflex (VOR)

Frontiers in Neurology, 2012
The experimental assessment of the vestibulo-ocular-reflex (VOR) gain provides an objective and quantitative measure of VOR performance which is nonetheless difficult to correlate with its efficiency in everyday living conditions.

Compensatory saccade in the vestibular impaired monkey

Frontiers in Neurology, 2023
IntroductionLoss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Patients with unilateral and bilateral vestibular deficits often use saccadic eye movements to compensate for an inadequate VOR.

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Vestibular-evoked myogenic potentials and video head impulse test in cochlear otosclerosis

The Egyptian Journal of Otolaryngology, 2023
Background Otosclerosis is one of the most common causes of hearing loss in adults with clinical onset between 20 and 40 years of age. Vestibular symptoms may be the most agonizing and primary symptom in cases with otosclerosis, so the assessment of ...
