Alcohol consumption significantly impairs postural stability by disrupting vestibular function, increasing the risk of falls. This study investigated the feasibility of using galvanic vestibular stimulation (GVS) to mitigate alcohol-induced postural instability in healthy adults, employing acute alcohol intake as a transient model of vestibular dysfunction....
No actionable change for audiology practice; this is a small feasibility study on an experimental application of GVS for alcohol-related balance disruption, well outside routine clinical vestibular management.
This feasibility work expands understanding of GVS as a potential real-time countermeasure for acute vestibular disruption, which could eventually inform rehabilitation technology for patients with vestibular dysfunction.
- 01Study tested galvanic vestibular stimulation (GVS) — mild electrical stimulation of the balance nerve — to counteract alcohol-induced unsteadiness.
- 02Alcohol impairs postural stability primarily by disrupting vestibular (inner-ear balance) processing.

- 04Feasibility design means the study was not powered to confirm efficacy — results are preliminary.
- 05GVS is already used in vestibular research but is not an established clinical treatment.
Galvanic vestibular stimulation can feasibly mitigate alcohol-induced postural instability caused by vestibular disruption.
