Abstract
Abstract Objective The purpose of this study was to understand if the vestibular-ocular reflex is related to scores from a computerized neurocognitive exam. Method Data was obtained via IRB-approved retrospective chart review. 109 youth athletes (median age 13; 73.3% male) participated in a pre-season baseline assessment consisting of the gaze stabilization test (GST; a measure of vestibular-ocular reflex function) and the ImPACT computerized neurocognitive test (CNT). ImPACT composite scores and GST velocities in the leftward and rightward directions were evaluated. A spearman correlation was utilized to determine the relationship between variables (GST and CNT). Results No significant relationship existed between rightward and leftward velocities and any ImPACT composite (highest value; r = 0.20, p > 0.05 for Right GST and Impulse Control). Conclusions There was no relationship between a measure of the vestibular-ocular reflex and CNT. Thus, the tests measure two distinct abilities that can be affected by sport-related concussion. Results indicate the importance of understanding pre- and post-injury function for both cognitive and vision function to guide clinical decision making.
