Assessing Otolith-Ocular Function With Video-Ocular Counter-Roll: Optimal Tilt Angles and Impact of Visual Inputs.
Yuchen Yang, Krishna Mukunda, Michael Schubert and 1 others
PMID 41189065WHAT IT FOUND
For video-ocular counter-roll testing, a 30-degree head tilt produces a higher gain than 60 or 90 degrees, so keep the standard angle.
Visual background lighting does not affect the measurement when the patient fixates on a target.
Key findings
01The ocular counter-roll gain was significantly higher at a 30-degree tilt compared to 60-degree and 90-degree tilts.
02There was no significant difference in vOCR measurements between room light and dark conditions.

What it does not show
The sample size was small (14 participants). All participants were healthy, so the findings do not describe how patients with vestibular deficits respond. The study assessed methodological parameters rather than diagnostic accuracy in a clinical population.
Declared interests
The authors have no conflicts of interest to disclose.
The easy way to misread this
Do not assume this study proves vOCR is an accurate diagnostic test for your patients. It only tested healthy volunteers to determine the best physical setup for the measurement, not how well the test identifies disease.
