Preliminary study using galvanic vestibular stimulation (GVS) to reduce unilateral spatial neglect (USN)

Galvanic vestibular stimulation in hemi-spatial neglect

Hemi-spatial neglect is an attentional disorder in which the sufferer fails to acknowledge or respond to stimuli appearing in contralesional space. In recent years, it has become clear that a measurable reduction in contralesional neglect can occur during galvanic vestibular stimulation, a technique by which transmastoid, small amplitude current induces lateral, attentional shifts via asymmetri...

Influence of the stimulus parameters of galvanic vestibular stimulation on unilateral spatial neglect.

Galvanic vestibular stimulation (GVS) stimulates the vestibular system electrically with low-amplitude direct current through surface electrodes applied to the left and right mastoids. The effects of GVS on unilateral spatial neglect (USN) in poststroke patients were recently reported, but the influence of the current intensity and application duration of GVS on USN has not been sufficiently in...

Disorders of body cognition following unilateral stroke - neuropsychological basis and modulation by galvanic vestibular stimulation (GVS)

Galvanic vestibular stimulation improves arm position sense in spatial neglect: a sham-stimulation-controlled study.

BACKGROUND Disturbed arm position sense (APS) is a frequent and debilitating condition in patients with hemiparesis after stroke. Patients with neglect, in particular, show a significantly impaired contralesional APS. Currently, there is no treatment available for this disorder. Galvanic vestibular stimulation (GVS) may ameliorate neglect and extinction by activating the thalamocortical network...

Can Galvanic Vestibular Stimulation Reduce Simulator Adaptation Syndrome?

Electrical stimulation of the vestibular sensory system during virtual environment simulations has been proposed as a method to reduce the incidence of simulator adaptation syndrome (SAS). However, there is limited empirical evidence to support this hypothesis. It is especially important to provide vestibular stimulation in driving simulators because an absence of vestibular cues may alter driv...
