Oculomotor Response as an Objective Assessment for Mild TBI in the Pediatric Population (2017-2018)
Brain injury in children is complex and common and is currently a leading source of injury and death. While mild traumatic brain injury (mTBI) is an important public health issue for both the general pediatric population and youth athletes, it is hard to quantify the physiological implications of concussions, making it difficult for clinicians to identify accurate diagnoses.
Since 2015, this team has been developing objective diagnostic tools to help clinicians diagnose, treat and mitigate concussive and sub-concussive events in children. Working with local youth sports programs, the team assessed athletes between ages five and 18 using an eye tracking protocol, created instructional videos for youth participants, developed a head-mounted portable tool for measuring concussions and established guidelines to help clinicians evaluate interventions.
In 2017-18, the team completed a third year of data acquisition in the local high school and youth football cohorts (Cardinal Gibbons High School and Durham Eagles Pop Warner Youth Football) and added a middle school team (Raleigh Revolution) to the study.
Team members gathered longitudinal data for a subset of its study population, including eye-tracking assessments, neurocognitive testing, symptom scoring, anthropometric measurements, head impact exposure data and weekly athletic activity reporting.

This Team in the News
I suffered two concussions within nine months, which affected me both physically and psychologically. After I came to Duke, I became interested in studying them. I also liked the project’s emphasis on pediatrics, because it’s a population that doesn’t get as much attention [when it comes to studying concussions]. The biggest reward for me was testing with the elementary school kids. The data we are collecting may impact the new generation.
