Factors Associated With Bilateral Involvement in Non‐Infectious Labyrinthitis: A Case–Control Study

The Laryngoscope, EarlyView.
Non‐infectious labyrinthitis may progress from unilateral to bilateral inner‐ear involvement, resulting in greater functional impairment. In this retrospective case–control study of 50 patients, younger age, female sex, and the presence of systemic disease were associated with bilateral involvement. These exploratory findings may help identify patients

Vestibular Function Pre‐ and Post‐cochlear Implantation in Adult Patients With Inner Ear Malformations: A Retrospective Cohort Study

Sensory Neuroscience, EarlyView.
This study investigated vestibular function in 129 adult patients with inner ear malformations (IEMs). The superior semicircular canal showed less impairment than the horizontal and posterior canals. Notably, cochlear implantation did not significantly exacerbate vestibular dysfunction at 12 months postoperatively.

Hybrid Model of the Context Dependent Vestibulo-Ocular Reflex: Implications for Vergence-Version Interactions

Frontiers in Computational Neuroscience, 2015
The vestibulo-ocular reflex (VOR) is an involuntary eye movement evoked by head movements. It is also influenced by viewing distance. This paper presents a hybrid nonlinear bilateral model for the horizontal angular vestibulo-ocular reflex (AVOR) in the ...

Video ocular counter roll: A bedside test of otolith‐ocular function

Annals of Clinical and Translational Neurology, 2023
Here we review the clinical value of a video‐oculography test for clinical evaluation of vestibular otolith function. This test is known as the video ocular counter roll (vOCR) and is based on measurement of torsional vestibulo‐ocular reflex with a ...

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Otolith is a critical component of the peripheral vestibular system responsible for detecting linear acceleration. Dysfunction of the otolith organs can lead to vertigo, balance disturbances, and gaze instability. By elucidating the physiological foundations and evaluating both current and emerging methods for assessing otolith ...

Manual head rotation synchronised to a metronome is a feasible and valid method for assessing visually enhanced vestibulo-ocular reflexes and vestibulo-ocular reflex suppression

Frontiers in Neurology
IntroductionThe visually enhanced vestibulo-ocular reflex (VVOR) and vestibulo-ocular reflex suppression (VOR-S) are critical in evaluating vestibular and cerebellar contributions to oculomotor control. This study aimed to investigate the feasibility and

Static Otolith Signals Reflect Clinical Course in Acute Vestibular Neuritis

Clinical Otolaryngology, EarlyView.
ABSTRACT Objectives To investigate how static and dynamic utricular functions differentially correlate with dizziness symptoms and quality of life (QoL) recovery in patients with acute vestibular neuritis (VN). Design Prospective observational study with 1‐week and 1‐month follow‐up assessments. Setting Tertiary referral centre. Participants Twenty‐six

Plasticity within non-cerebellar pathways rapidly shapes motor performance in vivo

Nature Communications, 2016
The extent to which non-cerebellar pathways can refine motor performance is debated. Here, the authors demonstrate behaviourally relevant patterns of activation evoke rapid plasticity within direct and indirect vestibulo-ocular reflex pathways in vivo ...

Nocturnal Hypoxemia Burden Correlates With Vestibular Dysfunction in Obstructive Sleep Apnea

Clinical Otolaryngology, EarlyView.
ABSTRACT Introduction Obstructive sleep apnea (OSA) is a potential contributor to vestibular dysfunction, though specific correlating parameters remain unclear. This study aimed to determine whether hypoxemia severity indices correlate quantitatively with caloric slow‐phase eye velocity (SPV), a marker of vestibular function. Methods In a retrospective
