Oculomotor Response as an Objective Assessment for Mild TBI in the Pediatric Population (2019-2020)

This multiyear Bass Connections project aimed to address the impact of sports-related concussions in children. Team members assessed youth athletes with an oculomotor assessment routine and compared these data to in-season documentation of concussion and level of impact/practice exposure. The sample population included youth athletes from five years of age to the high school level.

The team successfully completed a fifth year of data acquisition in the study’s high school through youth football league cohorts. Completion of this fifth year provided longitudinal data for a subset of the study population over their entire high school playing career. Additionally, this longitudinal and multiprogram model provided the opportunity to follow student-athletes across programs – from middle school to high school. Data acquisition within these cohorts included eye tracking assessments, neurocognitive testing, symptom scoring, anthropometric measurements and acquisition of head impact exposure data through the use of the Duke DASHR (earpiece sensor) and/or weekly athletic activity reporting. The team continued to develop a fully portable eye tracking system and collect additional longitudinal data.
