Table 1 Medians and quartiles (25th and 75th) 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.

From: Long-term effects of mild traumatic brain injuries to oculomotor tracking performances and reaction times to simple environmental stimuli

  1. 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.
