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 …

The Effects Of Previous Concussions On The Physiological Complexity Of Motor Output During A Continuous Isometric Visual-Motor Tracking Task, Adam C. Raikes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The long-term ramifications of single and multiple concussions are unclear, though they exist in the forefront of present social and scientific inquiry. While suicides linked to concussion histories by prominent current and former athletes sensationalize the issue, questions abound as to the safe and timely return to work, sport, and active military duty following a concussive event in addition to the link between concussion history and neurological disorders. As such, identifying lingering or persistent alterations in function following concussion is essential.

Nonlinear characteristics of visual-motor task performance, including the complexity of the performance, provide an avenue for quantifying visual processing, …
