    Abstract:
    OBJECTIVE: Vestibular and ocular motor dysfunction occurs in an estimated 60%-90% of concussion patients. The Vestibular/Ocular Motor Screening (VOMS) tool is validated for use in concussion patients older than 9 years. The goal of the current study was to adapt the current VOMS tool for a pediatric sample of children aged 5-9 years and establish its clinical utility in this patient population. METHODS: In this case-control study, 80 symptomatic concussion patients (n = 33 [41%] female) aged 5-9 years (mean age 7.40 ± 1.09 years) and 40 (n = 18 [45%] female) age- and sex-matched uninjured controls (mean age 7.10 ± 1.26 years) completed the VOMS-Child (VOMS-C), a version of the VOMS adapted for younger patients. Differences in binary "yes" or "no" symptom provocation for headache, dizziness, and nausea/"tummy ache" across the 7 items of the VOMS-C, and near point of convergence (NPC) distance, were examined. Logistic regression (LR) models were built to classify concussion and controls. Predicted probabilities were generated from the LR model and entered into receiver operating characteristic (ROC) curve models to generate area under the curve (AUC) values. RESULTS: VOMS-C item provocation ranged from 13% to 30% for concussed patients and 3% to 20% for controls. The LR model distinguished concussed participants from controls (R2 = 0.39; p < 0.001), with significant predictors being smooth pursuits, family depression history, and NPC distance. The ROC analysis had an AUC of 0.81 (95% CI 0.73-0.89; p < 0.001) in the good range. CONCLUSIONS: Accurate diagnosis of concussion in the clinic setting requires comprehensive evaluation in multiple domains, including detailed clinical interview, neurocognitive testing, and vestibular/ocular motor assessment, regardless of patient age. Our results provide preliminary support for the VOMS-C as a developmentally appropriate tool for concussion management.
