We investigated the influence of static head orientation and position, relative to the axis of body rotation, upon vestibular adaptation. With the head centered, displaced anterior to the axis of body rotation, or tilted 40 degrees to 45 degrees in roll or pitch, the gain of the vestibulo-ocular reflex (VOR) was trained (to go either up or down) for one hour using artificial manipulation of the...

Image stability during self-motion is achieved via a combination of the optokinetic and vestibulo-ocular reflexes (OKR and VOR). To determine whether distinct neuronal mechanisms are used to calibrate eye movements driven by visual and vestibular signals, we examined the developmental maturation and adaptive plasticity of the OKR and VOR in mice. The combined performance of the OKR and VOR, mea...

UNLABELLED Individuals with vestibular dysfunction may experience visual vertigo (VV), in which symptoms are provoked or exacerbated by excessive or disorientating visual stimuli (e.g. supermarkets). VV can significantly improve when customized vestibular rehabilitation exercises are combined with exposure to optokinetic stimuli. Virtual reality (VR), which immerses patients in realistic, visua...

Virtual reality (VR) training that provides optic flow stimuli and visuo-vestibular conflict has been suggested as a way to treat patients with inappropriate visual dependence (sometimes called visual vertigo even though spinning sensation is often absent). We propose a simple framework based on a hypothesis that the degree of dizziness depends on the offsetting between the destabilizing effect...

Patients with bilateral vestibular loss suffer from severe balance deficits during normal everyday movements. Ballet dancers, figure skaters, or slackliners, in contrast, are extraordinarily well trained in maintaining balance for the extreme balance situations that they are exposed to. Both training and disease can lead to changes in the diffusion properties of white matter that are related to...

Dynamic motion simulators cannot provide the same stimulation of sensory systems as real motion. Hence, only a subset human senses should be targeted. For providing vestibular stimulus, an automatic bodily function vestibular–ocular reflex (VOR) can objectively measure how accurate simulation is. This requires model ocular response to enforced accelerations, attempt create which is shown in thi...

background: centre of pressure displacement is an indicator of postural control. children with cerebral palsy have poor postural control. one common intervention to enhance their balance is vestibular stimulation. the aim of this research was to investigate the effect of vestibular stimulation on cop parameters in children with cerebral palsy (3-10 years old). methods: this study was a randomiz...

Background: Slackline-training has been shown to improve mainly task-specific balancing skills. Non-task specific effects were assessed for tandem stance and preferred one-leg stance on stable and perturbed force platforms with open eyes. It is unclear whether transfer effects exist for other balancing conditions and which component of the balancing ability is affected. Also, it is not known wh...

Introduction: Presence of vestibular schwannoma and a simultaneous glomus jugulare tumor is an extremely rare event. There is only one case report regarding the incidence of a contralateral vestibular schwannoma, along with a glomus jugulare tumor. Herein, we present the second case with a contralateral tumor.   Case Report: A 69-year-old woman presented with a long hist...
