Investigating head-neck stabilization using combined mechanical and galvanic vestibular stimuli

The goal of this study was to assess if the superposition principle is valid in head-neck stabilization during combined torso perturbations and continuous galvanic vestibular stimulation. Nine seated subjects were perturbed in lateral direction on a motion platform while GVS was simultaneously applied. Both the mechanical and galvanic input...

Galvanic vestibular stimulation elicits consistent neck motion in seated subjects

Galvanic vestibular stimulation (GVS) alters the firing rates of vestibular afferents and consequently provokes the illusion of movement. In standing balance GVS is used to assess the contribution of the vestibular system, where it has been shown to elicit coherent responses in lower extremity muscles involved in maintaining balance. However, to...
