Visual-vestibular interactions: I. Influence of peripheral vision on suppression of the vestibulo-ocular reflex and visual acuity.
Legibility of head-fixed displays in some motion environments is partially dependent upon visual suppression of the vestibuloocular reflex (VOR). This study investigates the effects of differing relationships between peripheral background movement and whole-body motion on the VOR and on visual performance. The purpose of the study is to explore factors in motion environments that influence perf...
متن کاملVestibular rehabilitation with visual stimuli in peripheral vestibular disorders.
INTRODUCTION Visual stimuli can induce vestibular adaptation and recovery of body balance. OBJECTIVE To verify the effect of visual stimuli by digital images on vestibular and body balance rehabilitation of peripheral vestibular disorders. METHODS Clinical, randomized, prospective study. Forty patients aged between 23 and 63 years with chronic peripheral vestibular disorders underwent 12 se...
متن کاملOcular Motor Function in Patients with Bilateral Vestibular Weakness
Introduction: Patients with bilateral weakness (BW) have many difficulties in gaze stability that interfere with their normal function. The aim of this study was to evaluate ocular motor functions in patients with BW to better understand the problem of gaze instability in these patients. Materials and Methods: Patients were referred from the Otolaryngology Department for Vestibular Assessmen...
متن کاملVestibulo-ocular physiology underlying vestibular hypofunction.
The vestibular system detects motion of the head and maintains stability of images on the fovea of the retina as well as postural control during head motion. Signals representing angular and translational motion of the head as well as the tilt of the head relative to gravity are transduced by the vestibular end organs in the inner ear. This sensory information is then used to control reflexes r...
متن کاملCorrelation between vestibulo-ocular reflex and optokinetic afternystagmus in normal subjects and in patients with vestibular system disorders.
Optokinetic afternystagmus follows optokinetic nystagmus as an expression of the central velocity storage integrator discharge and its fast phase is beating in the same direction as the previous optokinetic nystagmus. We investigated the correlation between vestibulo-ocular reflex and optokinetic afternystagmus in normal subjects and in patients with bilateral vestibular disorders. The aim of t...
