Context:
Biological sex and history of motion sickness are known modifiers associated with a false-positive baseline Vestibular/Ocular Motor Screening (VOMS). However, other factors may be associated with a false-positive VOMS in collegiate athletes.
Objective:
To identify contributing factors to false-positive VOMS assessments using population-specific criteria. We also critically appraised previously reported interpretation criteria.
Design:
Descriptive laboratory study.
Setting:
Single-site collegiate athletic training clinic.
Patients Or Other Participants:
National Collegiate Athletic Association Division I athletes (n = 462 [41% female]) aged 18.8 ± 1.4 years.
Main Outcome Measure(S):
Participants completed the Athlete Sleep Behavior Questionnaire, the 7-Item Generalized Anxiety Index, the Immediate Postconcussion Assessment and Cognitive Testing battery, the Patient Health Questionnaire-9, the Revised Head Injury Scale, the Sensory Organization Test, and the VOMS as part of a multidimensional baseline concussion assessment. Participants were classified into 2 groups based on whether they had a total symptom score of greater than or equal to 8 after VOMS administration, excluding the baseline checklist. We used χ2 and independent t tests to compare group demographics. A binary logistic regression with adjusted odds ratios (ORs) was used to evaluate the influence of sex, corrected vision, attention-deficit/hyperactivity disorder, Immediate Postconcussion Assessment and Cognitive Testing composite scores, concussion history, history of treatment for headache and/or migraine, Generalized Anxiety Index scores, Patient Health Questionnaire-9 scores, Athlete Sleep Behavior Questionnaire scores, and Sensory Organization Test equilibrium scores and somatosensory, visual, and vestibular sensory ratios on false-positive rates.
Results:
Approximately 9.1% (42 of 462 [30 females]) met criteria for a false-positive VOMS. A significantly greater proportion of females had false positives (χ21 = 18.37, P < .001). Female sex (OR = 2.79; 95% CI = 1.17, 6.65; P = .02) and history of treatment for headache (OR = 4.99; 95% CI = 1.21, 20.59; P = .026) were the only significant predictors of false-positive VOMS. Depending on cutoff interpretation, false-positive rates using our data ranged from 9.1% to 22.5%.
Conclusions:
Our results support the most recent interpretation guidelines for the VOMS in collegiate athletes due to a low false-positive rate and ease of interpretation. Biological sex and history of headaches should be considered when administering the VOMS in the absence of a baseline.
