The vestibular ocular motor screen (VOMS) and the Sport Concussion Assessment Tool 6 (SCAT6) are point-of-care concussion assessments administered immediately or soon after sports participation or exercise. To retain validity and accuracy, the results of these tests should not be affected by sporting activity. We assessed the effect on the mVOMS (modified VOMS) and SCAT6 immediately and 20 minutes after performance training in high school athletes.
DESIGN:
Nonrandomized pilot experimental study.
SETTING:
High School, Buffalo, NY.
PARTICIPANTS:
Nonconcussed athletes (n = 23, 39% male, 15.5 ± 1.0 years).
INDEPENDENT VARIABLE:
Performance Training (pretraining, post-training, 20 minutes post-training).
MAIN OUTCOME MEASURES:
mVOMS and SCAT6 scores (standardized assessment of concussion, modified balance error scoring system, timed tandem gait [TTG], dual task tandem gait [DTTG]).
RESULTS:
TTG (
CONCLUSIONS:
SCAT6 and mVOMS performance was not adversely affected by moderately intense exercise training in high school athletes. TTG and DTTG performance improved after exercise, consistent with the learning effect. Further research should be conducted across other populations to increase generalizability. Clinicians should be confident that fatigue and exertion from acute performance training activities are not likely to affect the performance of these widely used sideline concussion assessment tools.
