Subclinical Neck Pain Alters Gaze Stability During the Vestibulo-Ocular Reflex

Applied Sciences
(1) Background: Subclinical neck pain is mild-to-moderate neck pain that has not yet been treated, and where individuals experience pain-free days. Alterations in sensorimotor integration, motor control, proprioception, and cerebellar inhibition have ...

Vestibulo-ocular reflex and the head impulse test

Arquivos de Neuro-Psiquiatria, 2012
The authors highlights the importance of the vestibulo-ocular reflex examination through the head impulse test as a diagnostic method for vestibular dysfunction as well as, and primarily, a bedside semiotic resource capable of differentiating between ...

Three-dimensional vestibular eye and head reflexes of the chameleon: characteristics of gain and phase and effects of eye position on orientation of ocular rotation axes during stimulation in yaw direction [PDF]

, 2018
We investigated gaze-stabilizing reflexes in the chameleon using the three-dimensional search-coil technique. Animals were rotated sinusoidally around an earth-vertical axis under head-fixed and head-free conditions, in the dark and in the light.

Multimodal Gaze Stabilization of a Humanoid Robot based on Reafferences

, 2017
Gaze stabilization is fundamental for humanoid robots. By stabilizing vision, it enhances perception of the environment and keeps points of interest in the field of view.

Semicircular Canal Influences on the Developmental Tuning of the Translational Vestibulo-Ocular Reflex

Frontiers in Neurology, 2018
Vestibulo-ocular reflexes (VORs) rely on neuronal computations that transform vestibular sensory signals into spatio-temporally appropriate extraocular motor commands.

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

Clinical Anatomy, EarlyView.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

The Automated Vestibular Rehabilitation System: Normative Data From a Machine Vision‐Guided Platform

The Laryngoscope, EarlyView.
The Automated Vestibular Rehabilitation System (AVRS) is a machine vision‐based tool designed to increase accessibility to vestibular rehabilitation therapy by automating exercise delivery and tracking head‐eye movements in real time. In n = 40 healthy adults, the AVRS accurately measured vestibulo‐ocular reflex (VOR) gain values near physiologic norms

Vestibular Dysfunction in Parkinson's Disease: A Systematic Review of Signs and Symptoms

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Despite the growing interest in the link between Parkinson's disease (PD) neuropathology and vestibular system, there is still a lack of consensus about the presence of vestibular dysfunctions in PD. Objective This review aims to identify vestibular signs and symptoms reported in PD patients and to summarize and critically appraise ...

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 ...

Differential regulations of vestibulo-ocular reflex and optokinetic response by β- and α2-adrenergic receptors in the cerebellar flocculus

Scientific Reports, 2017
Norepinephrine modulates synaptic plasticity in various brain regions and is implicated in memory formation, consolidation and retrieval. The cerebellum is involved in motor learning, and adaptations of the vestibulo-ocular reflex (VOR) and optokinetic ...
