A New Suppression Index Calculation Using the Visually Enhanced Vestibulo-Ocular Reflex and Vestibulo-Ocular Reflex Suppression Paradigms in the Video Head Impulse Test [PDF]
Audiology ResearchThe aim of this study is to calculate the gains of the quantified visually enhanced vestibulo-ocular reflex (qVVOR) and the quantified vestibulo-ocular reflex suppression (qVORS), using a specific system to generate a visual suppression index (SI) in ...

Visually enhanced vestibulo‐ocular reflex gain in patients with vestibular disease [PDF]
Laryngoscope Investigative Otolaryngology, 2023 Objective Vestibular migraine (VM) is a diagnostic challenge. Visually enhanced vestibulo‐ocular reflex (VVOR) gain, a measure of the visual–vestibular interaction, has been proposed as a tool for diagnosing VM.

Vestibulo-Ocular Reflex Suppression: Clinical Relevance and Assessment in the Digital Age [PDF]
Digital BiomarkersBackground: Visual acuity and image stability are crucial for daily activities, particularly during head motion. The vestibulo-ocular reflex (VOR) and its suppression (VORS) support stable fixation of objects of interest.

The vestibular implant: effects of stimulation parameters on the electrically-evoked vestibulo-ocular reflex [PDF]
Frontiers in NeurologyIntroductionThe vestibular implant is a neuroprosthesis which offers a potential treatment approach for patients suffering from vestibulopathy. Investigating the influence of electrical stimulation parameters is essential to improve the vestibular ...

Vestibulo-Ocular Reflex Is Modulated by Noisy Galvanic Vestibular Stimulation [PDF]
Frontiers in Neurology, 2022 We investigated whether noisy galvanic vestibular stimulation (nGVS) modulates the vestibulo-ocular reflex (VOR) and whether this effect is correlated with the effect of nGVS on body sway. Thirty healthy young adults participated.

Head shaking does not alter vestibulo ocular reflex gain in vestibular migraine [PDF]
Frontiers in Neurology, 2022 Vestibular Migraine (VM) is the most common cause of non-positional episodic vestibular symptoms. Patients with VM commonly report increased motion sensitivity, suggesting that vestibular responses to head movement may identify changes specific to VM ...

Evaluation of the vestibulo-ocular reflex in head-tilt mutant mice [PDF]
Biochemistry and Biophysics ReportsThe vestibulo-ocular reflex (VOR) is an involuntary reflex essential for maintaining clear vision and balance during head movement. It stabilizes gaze by generating compensatory eye movements in the opposite direction to head movement, ensuring that the ...

Sound-Evoked Responses in the Vestibulo-Ocular Reflex Pathways of Rats [PDF]
Frontiers in Neuroscience, 2021 Vestibular evoked myogenic potentials (VEMP) have been used to assess otolith function in clinics worldwide. However, there are accumulating evidence suggesting that the clinically used sound stimuli activate not only the otolith afferents, but also the ...

Emerging and distinct video head impulse test responses in elderly with vestibular symptoms
Brazilian Journal of Otorhinolaryngology, 2022 Introduction: Dizziness has been reported to be the most common symptom in elderly population. Video head impulse test, VHIT, allows clinicians to assess the vestibular function in elderly individuals, during their initial stages of vestibular symptoms ...
