Purpose: To quantify differences in nonlinear aspects of performance on a seated visual-motor tracking task between clinically asymptomatic males and females with and without a self-reported mild traumatic brain injury (mTBI) history.
Methods: Seventy-three individuals with a self-reported concussion history (age: 21.40 ± 2.25 years) and 75 without (age: 21.50 ± 2.00 years) completed the visual-motor tracking task. Participants pressed an index finger against a force sensor, tracing a line across a computer screen (visual-motor tracking). The produced signal's root-mean-square error (RMSE), sample entropy (SampEn, a measure of regularity), and average power (AvP) between 0 and 12 Hz were calculated. …
