Postural control requires continuous sensorimotor feedback to maintain balance and prevent falls. Noisy galvanic vestibular stimulation (nGVS), a weak stochastic electrical stimulus applied to the peripheral vestibular apparatus, can reduce postural sway during unperturbed steady standing....

Discussion
Signed responses from readers of the wire.
This is early-stage neurophysiology research; no actionable change to vestibular or balance rehabilitation practice is warranted at this time.
Understanding how nGVS modulates reactive balance could open a pathway for non-invasive vestibular therapies in patients with balance disorders, a population commonly seen alongside hearing loss.
- 01nGVS (noisy galvanic vestibular stimulation) is a non-invasive electrical technique targeting the vestibular system.
- 02The study measured reactive postural control and neuromuscular responses during unexpected surface perturbations.
- 03Findings suggest nGVS can modulate the reflex pathways that help the body recover from sudden balance disturbances.

- 05Results are preliminary and specific to controlled lab conditions, limiting immediate clinical translation.
