Evaluation Of Long-Term Effects Of Mild Traumatic Brain Injury On Visual Motor Control Of Ncaa Division I Football Athletes, Kathryn Delost

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Context: Current concussion evaluation assessments rely largely on static measures that may not detect subtle changes in behavior. Dynamic evaluation, such as visual-motor tracking tasks, may reveal subtle and meaningful changes in motor behavior post-concussion. Objective: This study compared measurements of performance regularity over a time series (approximate entropy; ApEn), which was derived from a visual-motor tracking task performed before concussion, post concussion, and at one month, three months, and six months post concussion. ApEn values were compared for number of previous concussions and playing position groups. Design: ApEn values were collected from the visual-motor tracking task, and history of …
