Electrotactile feedback of sway position improves postural performance during galvanic vestibular stimulation.
The purpose of this study was to assess the influence of electrotactile feedback on postural control performance during binaural galvanic vestibular stimulation (GVS). Postural equilibrium was measured with a computerized hydraulic platform in 10 healthy adults (6M, 4F, 24-65 y). Feedback of anterior-posterior (AP) and mediallateral (ML) body sway was derived from a 2-axis linear accelerometer ...
متن کاملAnalysis on Effects of Galvanic Vestibular Stimulation on Postural Stability using 3D Motion Analysis
This paper presents the analysis on effects of GVS(Galvanic Vestibular Stimulation) to mastoid process on postural balance and stability using 3 dimensional motion analysis. The experiments were performed by providing the experimental subjects a bipolar binaural galvanic vestibular stimulation during standing and walking, and then the postural stability was evaluated by 3 dimensional motion ana...
متن کاملEffects of galvanic vestibular stimulation on postural limb reflexes
25 26 Quadrupeds maintain the dorsal side up body orientation due to the activity of the 27 postural control system driven by limb mechanoreceptors. Binaural galvanic vestibular 28 stimulation (GVS) causes a lateral body sway towards the anode. Previously we have 29 shown that this new position is actively stabilized, suggesting that GVS changes a set30 point in the reflex mechanisms controllin...
متن کاملSomatosensory influence on postural response to galvanic vestibular stimulation.
We investigated how postural responses to galvanic vestibular stimulation were affected by standing on a translating support surface and by somatosensory loss due to diabetic neuropathy. We tested the hypothesis that an unstable surface and somatosensory loss can result in an increase of vestibulospinal sensitivity. Bipolar galvanic vestibular stimulation was applied to subjects who were standi...
متن کاملEffects of galvanic vestibular stimulation on postural limb reflexes and neurons of spinal postural network.
Quadrupeds maintain the dorsal side up body orientation due to the activity of the postural control system driven by limb mechanoreceptors. Binaural galvanic vestibular stimulation (GVS) causes a lateral body sway toward the anode. Previously, we have shown that this new position is actively stabilized, suggesting that GVS changes a set point in the reflex mechanisms controlling body posture. T...
