Noisy 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 کاملGalvanic 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 کاملShort-duration galvanic vestibular stimulation evokes prolonged balance responses.
The application of galvanic vestibular stimulation (GVS) evokes distinct responses in lower limb muscles involved in the control of balance. The purpose of this study was to investigate the balance and lower limb muscle responses to short-duration GVS and to determine whether these responses are modulated by small changes in center of gravity (CoG) and baseline muscle activity occurring during ...
متن کاملEffects of Galvanic Vestibular Stimulation on Statokinesigrams of the Elderly
Special suits have been designed to simulate the physical functions of the elderly. However, it has been suggested that these suits do not simulate the postural instability that is actually observed in elderly subjects. We consider that postural instability in the elderly is caused by anomalous signals in the vestibules. In this study, we have verified this hypothesis by using galvanic vestibul...
متن کاملAsymmetry of balance responses to monaural galvanic vestibular stimulation in subjects with vestibular schwannoma☆
OBJECTIVE We investigated the potential of galvanic vestibular stimulation (GVS) to quantify lateralised asymmetry of the vestibulospinal pathways by measuring balance responses to monaural GVS in 10 subjects with vestibular schwannoma and 22 healthy control subjects. METHODS Subjects standing without vision were stimulated with 3 s, 1 mA direct current stimuli delivered monaurally. The mean ...
