Determining the Agreement Between Common Measures Related to Vestibulo-ocular Reflex Function After a Mild Traumatic Brain Injury in Children and Adolescents.
Adrienne Crampton, Kathryn J Schneider, Lisa Grilli and 5 others
PMID 36123987WHAT IT FOUND
Symptom provocation during vestibular screening did not agree with performance-based tests of eye-head coordination in children with concussion.
Clinicians should not use one to infer the other, as they likely measure different things.
Key findings
01There was no meaningful agreement between symptom provocation during VOR testing and performance-based measures of VOR function.
02Fair agreement was found between the clinician-observed VOR items of the VOMS and the clinical head thrust test.
03Children with cervical spine findings reported more headache and dizziness during VOR testing than those without such findings.

What it does not show
The sample size was small, and few participants had abnormal findings on performance-based tests, which limits the reliability of the agreement statistics. Participants were recruited from specialized clinics, which may bias the sample toward more complicated recoveries. Assessments occurred on average 18 days post-injury, meaning natural recovery may have reduced the number of observable deficits. The study is a substudy of a larger project, so it was not powered specifically to detect agreement between these measures.

The easy way to misread this
Do not interpret a child's report of dizziness or headache during head movement screening as proof that their vestibulo-ocular reflex is mechanically impaired. The study found no agreement between these symptoms and performance-based tests, suggesting they measure different things.
