The visually enhanced vestibulo-ocular reflex (VVOR) and vestibulo-ocular reflex suppression (VOR-S) are critical in evaluating vestibular and cerebellar contributions to oculomotor control. This study aimed to investigate the feasibility and reliability of metronome-synchronised, manual head rotation video-oculography for evaluating VVOR and VOR-S in healthy participants....
Clinicians without access to motorized rotary chair equipment may consider metronome-guided manual head rotation as a validated, low-cost alternative for assessing VVOR and VOR suppression, though replication in larger and more diverse samples is advisable before routine adoption.
Validating a low-tech method for vestibulo-ocular reflex assessment could democratize balance testing in clinics with limited equipment budgets.
- 01Manual head rotation timed to a metronome was tested as a vestibular assessment tool.
- 02Method assessed visually enhanced vestibulo-ocular reflex (VVOR) and VOR suppression.
- 03Study reports the approach is both feasible and valid.
- 04Published in Frontiers in Neurology (2026).
- 05Could lower the equipment cost barrier for vestibular testing.
Manual head rotation synchronized to a metronome is a feasible method for assessing VVOR and VOR suppression.
