The Vestibular/Ocular Motor Screening (VOMS) measure is a newly developed vestibular and ocular motor symptom provocation screening tool for sport-related concussions. Baseline data, psychometric properties, and reliability of the VOMS are needed to further understand the applications of this tool, especially in the youth population, where research is scarce.Purpose:
To establish normative data and document the internal consistency and false-positive rate of the VOMS in a sample of nonconcussed youth athletes.Study Design:
Cross-sectional study; Level of evidence, 3.Methods:
A total of 423 youth athletes (male = 278, female = 145) between the ages of 8 and 14 years completed baseline VOMS screening before the start of their respective sport seasons. Internal consistency was measured with Cronbach α and inter-item correlations.Results:
Approximately 60% of youth athletes reported no symptom provocation on baseline VOMS assessment, with 9% to 13% scoring over the cutoff levels (score of ≥2 for any individual VOMS symptom, near point convergence distance of ≥5 cm). The VOMS displayed a high internal consistency (Cronbach α = .97) at baseline among youth athletes.Conclusion:
The current findings provide preliminary support for the implementation of VOMS baseline assessment into clinical practice, due to a high internal consistency, strong relationships between VOMS items, and a low false-positive rate at baseline in youth athletes.
