Vestibular System Disorder Clinical Trial
Official title:
The Effect of Galvanic Stimulation on vHIT and VEMP Tests
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.
