Summary

Introduction: Galvanic vestibular stimulation (GVS) is a well-established technique with a history spanning over a century, primarily used to manipulate the vestibular system. Recent interest has surged in its potential for understanding human vestibular function and aiding in functional recovery. GVS applies electrical currents to the mastoid region, modulating vestibular afferents, and induces specific effects based on the participant's posture and current polarity. While GVS's impact on the central nervous system and its potential to aid in functional recovery have been studied, its immediate effects on vestibular reflexes remain less explored. Methods: In this study, thirty healthy adult participants underwent ocular and cervical vestibular evoked myogenic potential (VEMP) tests, as well as the velocity Head Impulse Test (vHIT) before and immediately after one hour of GVS application. Statistical analyses were performed to assess changes in VEMP and vHIT results.

Type	Name	Description
DEVICE	Galvanic Vestibular Stimulation	Galvanic Vestibular Stimulation (GVS) is a non-invasive technique that uses low-level electrical currents to stimulate the vestibular system, affecting balance, posture, and eye movements. It has applications in research, clinical assessment, and rehabilitation of vestibular and balance-related issues, as well as potential applications in cognitive and motor function enhancement.
