Signed responses from readers of the wire.
If the study identifies a clearly superior montage, clinicians performing oVEMP testing should consider adopting that configuration to standardise results — but the specific findings should be reviewed before changing lab protocols.
Standardising oVEMP electrode placement could reduce variability across clinics, improving the reliability of vestibular function assessments used in diagnosing inner ear and balance disorders.
- 01Three electrode montages tested: infraorbital, chin, and belly-tendon references.
- 02Air-conducted tone burst stimulation used — a common, non-invasive oVEMP stimulus type.
- 03Study aims to resolve ongoing lack of consensus on optimal oVEMP electrode configuration.
- 04oVEMP assesses utricular and superior vestibular nerve function, critical for balance disorder diagnosis.
- 05Findings could inform standardised clinical protocols for vestibular evoked myogenic potential testing.
One electrode montage among the three tested provides an optimal configuration for oVEMP recording with air-conducted tone burst stimulation.
