Galvanic Vestibular Stimulation Induces a Spatial Bias in Whole-body Position Estimates.
Peripheral galvanic vestibular stimulation (GVS) has been shown to temporarily ameliorate left spatial neglect [1]. Specifically, anodal (facilitatory) stimulation over the left mastoid bone coupled with cathodal (inhibitory) over the right mastoid reduces visuospatial‐neglect scores in line cancellation [2] and line bisection tasks [3, 4]. This montage increases activity in the left vestibular...
متن کاملGalvanic 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...
متن کاملGalvanic 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...
متن کاملNoisy galvanic vestibular stimulation induces a sustained improvement in body balance in elderly adults
Vestibular dysfunction causes postural instability, which is prevalent in the elderly. We previously showed that an imperceptible level of noisy galvanic vestibular stimulation (nGVS) can improve postural stability in patients with bilateral vestibulopathy during the stimulus, presumably by enhancing vestibular information processing. In this study, we investigated the after-effects of an imper...
متن کاملHabituation to Galvanic Vestibular Stimulation during Gait
Balance requires the integration of proprioceptive, visual, and vestibular sensory inputs. Contributions from the vestibular system are increasingly important when other sensory signals are lacking or erroneous [1]. Galvanic vestibular stimulation (GVS), the application of a small electrical current across the mastoid processes, has been used to apply a stimulus to the vestibular system indepen...
