Context: Current concussion assessments use static measures that may overlook subtle impairments. Visual-motor tracking tasks provide an option for dynamic evaluation of behavior post-concussion, which might reveal subtle and meaningful changes in motor behavior. Objective: This study compared measurements of performance regularity over time (approximate entropy; ApEn), obtained from a visual-motor tracking task, captured both pre and post concussion. Visual-motor tracking performance was compared to the Standard Assessment of Concussion (SAC) and the modified Balance Error Scoring System (mBESS).
