  • The purpose of the present study was to examine the relationship between demographic and health factors, and oculomotor functioning during baseline testing in professional athletes. Four hundred twenty-eight male athletes consented and participated in the baseline concussion assessments of the Canadian Football League (CFL). Athletes ranged from 21 to 40 years of age (M =26.44, SD =2.873), and reported a history of 0, 1, or 2+ sport-related concussions (SRCs). All athlete participants completed the Head Check questions of demographics and medical history, and the EYE-SYNC saccade test to explore how the presence of a history of concussions, Attention-Deficit/Hyperactivity Disorder (ADHD), Learning Disability (LD), age, and post-exertion influenced baseline measures of oculomotor functioning using the EYE-SYNC saccade outcomes of accuracy and precision. Correlations revealed no significant relationships between combined vertical and horizontal saccade outcomes (LeftAccuracyXY, LeftPrecisionXY, RightAccuracyXY, RightPrecisionXY) and the demographic/health variables (p > .05). Independent t-tests indicated no significant differences in mean saccade performance between athletes with and without ADHD and/or LD (p > .05). Furthermore, three-way multiple analysis of variance (MANOVA) run with age group (21-25, 26-30, 31-40) and concussion group (0, 1, 2+) revealed no main effects of age, F(8, 844) = .914, p = .504, Wilks’ = .983, partial η2 = .0) or history of concussion, F(8, 510) = .856, p = .554, Wilks’ = .974, partial η2 = .013). A one-way repeated measures analysis of variance (MANOVA) revealed no significant differences from pre- to post-exertion assessments, F(4, 56) = .411, p = .800, Wilks’ = .971. The oculomotor functioning of CFL athletes at baseline, measured using the EYE-SYNC saccade task, does not appear to be influenced by a history of concussion, ADHD, LD, age, or physical exertion. This information may help professionals with their clinical decision-making regarding the diagnosis of SRCs, and return-to-play.
