High-velocity angular vestibulo-ocular reflex adaptation to position error signals.
TLDR
The findings suggest that some subjects can increase their aVOR gain in response to high-velocity active head movement training using a position ES, suggesting that retinal slip is a more powerful aVor gain modifier.Abstract:
Background and Purpose:Vestibular rehabilitation strategies including gaze stabilization exercises have been shown to increase gain of the angular vestibulo-ocular reflex (aVOR) using a retinal slip error signal (ES). The identification of additional ESs capable of promoting substitution strategiesread more

Vestibulo-Ocular Reflex Stabilization after Vestibular Schwannoma Surgery: A Story Told by Saccades.
Angel Batuecas-Caletrio,Jorge Rey-Martinez,Gabriel Trinidad-Ruiz,Eusebi Matiño-Soler,Santiago Santa Cruz-Ruiz,Angel Muñoz-Herrera,Nicolas Perez-Fernandez +6 more
TL;DR: The scatter of compensatory saccades (as measured by the PR score) may be a surrogate early marker of clinical recovery, given its relationship to the Dizziness Handicap Inventory.
Journal ArticleDOI
Functional Head Impulse Testing Might Be Useful for Assessing Vestibular Compensation After Unilateral Vestibular Loss.
TL;DR: The results show a strong relationship between self-generated movements, latencies of covert saccades and outcome in HITD-FT, i.e., a better dynamic visual function with less retinal slip which is the main function of the VOR.

New advances regarding adaptation of the vestibulo-ocular reflex.
TL;DR: This is a review summarizing the development of vestibulo-ocular reflex adaptation behavior with relevance to rehabilitation over the last 10 years and follows the outline below.

Multiple timescales in the adaptation of the rotational VOR
Paolo Colagiorgio,Giovanni Bertolini,Christopher J. Bockisch,Dominik Straumann,Stefano Ramat +4 more
TL;DR: A mathematical model of rVOR adaptation is developed based on two hidden-states processes, which adapts the cerebellar-forward model of the ocular motor plant, and shows that it accurately simulates the experimental data on rV OR gain adaptation, whereas a single timescale learning process fails to do so.

The Role of Neck Input in Producing Corrective Saccades in the Head Impulse Test
Y. Iwasaki,Teru Kamogashira,Chisato Fujimoto,Kayoko Kabaya,Makoto Kinoshita,Tatsuya Yamasoba +5 more
TL;DR: In this article , the role of neck input in generating overt as well as covert saccades was examined, where the neck is fixed by a cervical collar (neck lock extrication collar) to reduce somatosensory input from the neck.

Clinical Neurophysiology of the Vestibular System
Robert W. Baloh,V. Honrubia +1 more
TL;DR: This book provides a framework for understanding the pathophysiology of diseases involving the vestibular system and outlines the important features in the patient's history, examination, and laboratory evaluation that determine the probable site of lesion.
Journal ArticleDOI
Frequency and velocity of rotational head perturbations during locomotion.
TL;DR: During locomotion, the head is stabilized in space incompletely but adequately so that the vestibulo-ocular reflex (VOR) is not saturated and during vigorous, voluntary head rotations, the maximum head velocity exceeds the range where the VOR can stabilize gaze.

Recovery of Dynamic Visual Acuity in Bilateral Vestibular Hypofunction
TL;DR: Exercises may foster the use of centrally programmed eye movements that could substitute for the vestibulo-ocular reflex in patients with unilateral vestibular hypofunction, and the DVA-predictable would benefit more from this than would Dva-unp Predictable.

Signal processing in the vestibular system during active versus passive head movements.
TL;DR: This review considers how head-in-space velocity is processed at the level of the vestibular afferents andvestibular nuclei during active versus passive head movements and implications for higher-level processing of Vestibular information during active head movements.

Mechanism of dynamic visual acuity recovery with vestibular rehabilitation.
TL;DR: The data suggest that vestibular rehabilitation increases aVor gain during active head rotation independent of peripheral aVOR gain recovery.
