Identifying Factors Associated with Head Impact Kinematics and Brain Strain in High School American Football via Instrumented Mouthguards

The Presence of the Temporal Horn Exacerbates the Vulnerability of Hippocampus During Head Impacts

“…Estimation of hippocampal response was obtained from the TH-Model and NTH-Model by simulating six representative football head impacts ( Table 2 and Supplementary Appendix SAB ). At Stanford University, instrumented mouthguards have been developed to measure six-degree-of-freedom head kinematics during in-game head impacts to athletes ( Liu et al, 2020 ; Cecchi et al, 2021 ). Using these instrumented mouthguards, over 500 head impacts in football have been video confirmed ( Hernandez et al, 2015 ).…”

2022 Athanasiou Student and Post-Doc Awards

“…A total of 16 awards have been selected from over 400 papers since 2020. 1,3,4,[7][8][9][10][11][12][13][14][15][16][17]19,20 This year, four awardees were selected to present their papers at the session. 1,3,8,10 The Athanasiou Student and Post-Doc Awards were selected from all papers with graduate student or post-doctoral scholar first authors that were published online in 2021.…”

“…1,3,4,[7][8][9][10][11][12][13][14][15][16][17]19,20 This year, four awardees were selected to present their papers at the session. 1,3,8,10 The Athanasiou Student and Post-Doc Awards were selected from all papers with graduate student or post-doctoral scholar first authors that were published online in 2021. There were a total of 146 papers that met the criteria, making the awardees the top 3% of those papers.…”

“…Cecchi et al investigated head impact kinematics and associated brain strain in high school American football via instrumented mouthguards to identify sport-specific factors associated with increased head impact incidence and severity. 8 Athlete brain health in American football is of growing concern, particularly in young adults, as repeated head impact exposure is known to increase the risk of progressive neurodegeneration. 2 In this study, 116 high school American football athletes were instrumented with mouthguards measuring peak linear acceleration, angular velocity, and angular acceleration.…”

Special Issue: Concussions

“…Instrumented mouthpieces and mouthguards have been designed to directly measure head impact acceleration and brain strain in relation to concussion. 5,9 In cycling and snow sports, advanced rotation-dampening systems have been evaluated and helmet damage was quantified using computed tomography (CT). 7,11 The future for concussion injury prevention is promising given the vast array of new helmet concussion injury prevention and evaluation technologies.…”
