“…A detailed description of the experimental design, eye tracking tasks and outcome variables are provided in an earlier study (Snegireva et al 2021) that assessed the reliability of 47 pre-specified variables across a range of established paradigms. The variables that demonstrated good or excellent reliability (ICC>0.75) (Koo and Li 2016, Post 2016, Murray et al 2017 along with variables with moderate reliability and percentage mean below 30% were included in the current analysis.…”

“…Thus, this study was set to investigate whether selected eye tracking variables measured across established tasks would constitute a valid tool to diagnose and monitor SRC in adult and youth participants in such contact sports as Rugby Union (rugby) and football (soccer). This research built on a previous study of reliability of selected eye tracking measures in athletics cohort that identified five variables that may be suited for SRC (Snegireva et al 2021). This study evaluated two key hypotheses.…”

Objective: Diagnosing a sports-related concussion (SRC) remains challenging, and research into diagnostic tools is limited. This study investigated whether selected eye tracking variables would be a valid tool to diagnose and monitor SRC in adult and youth participants in selected contact sports, such as Rugby Union (rugby) and football (soccer). Methods: This prospective cohort study, with 70 concussed and 92 non-concussed adult and youth athletes, assessed the validity of five previously selected eye tracking variables for SRC diagnostics and management. The performance between concussed and age-matched control (non-concussed) athletes, as well as between three successive testing sessions in the concussed athletes were compared. Self-paced saccade count in adult group; blink duration in the memory-guided saccade and sinusoidal smooth pursuit tasks, proportion of antisaccade errors, and gain of diagonal smooth pursuit in the youth group were assessed. Results: The youth concussed group had higher blink duration in the fast memory-guided saccades task (p = 0.001, η2 = 0.17) and a tendency for higher blink duration in the sinusoidal smooth pursuit task (p = 0.016, η2 = 0.06) compared to the youth control group. In both tasks the blink duration in the concussed youth group decreased from session 1 to session 2 by 24% and 18%, accordingly, although statistical significance was not reached. The concussed adult group demonstrated a lower number of self-paced saccades compared to controls (p = 0.05, η2 = 0.09), which gradually increased, with the largest difference between session 1 and session 3 (p = 0.02). Conclusions: Blink duration in youth athletes holds promise as a valid metric for concussion diagnostics and monitoring. It is recommended to focus future studies on comparing eye tracking performance within the same concussed athletes over time rather than comparing them to healthy controls.
