Quantitative assessment of vestibular nerve activity has been difficult with conventional electrophysiological techniques. This study aimed to develop a novel method combining galvanic vestibular stimulation (GVS) with 3-dimensional video-oculography (3D-VOG) to evaluate vestibular function noninvasively.

Discussion
Signed responses from readers of the wire.
This novel 3D video-oculography method for quantifying vestibular nerve responses to galvanic stimulation is promising as a diagnostic tool, but requires clinical validation before adoption in routine vestibular assessment.
A quantitative, standardized method for assessing vestibular nerve integrity could improve the precision of vestibular diagnostics beyond currently available clinical tests.
- 01Combines galvanic vestibular stimulation (mild electrical current to the mastoid) with 3D video-oculography to map eye movements.
- 02Aims to quantitatively measure vestibular nerve activity in three dimensions.
- 03Represents a novel methodological development in vestibular function testing.
- 04Could supplement existing tests such as caloric testing and video head impulse tests.
