Medians and quartiles (25^th and 75^th) across participants from Control and mTBI groups for variables of interest recorded during the execution of the horizontal smooth pursuit task at 0.10 Hz.

	Control Median (25th; 75th Quart.)	mTBI Median (25th; 75th Quart.)	Mann–Whitney U tests (p-value)
Accuracy Smooth Pursuit a	0.03 (0.01; 0.05)	0.06 (0.02; 0.09)	0.0600
Asymmetry (%)	0.26 (−0.54; 0.99)	0.36 (−0.58; 2.13)	0.5064
Phase (°)	0.32 (−0.13; 0.78)	0.35 (−0.18; 1.32)	0.4046
Intrusive Saccades (%)	17.56 (11.62; 24.34)	32.98 (23.51; 51.20)	0.0000

^aAccuracy Smooth Pursuit was defined as the absolute error obtained between the averaged gain values computed between the slow phase component of eye velocity and the pursuit tracker stimuli. Perfect accuracy is evidenced when Accuracy Smooth Pursuit is equal to zero, while any positive value (Accuracy Smooth Pursuit > 0) indicates less accurate tracking.
