Correction: Rotational Head Kinematics in Football Impacts: An Injury Risk Function for Concussion
-
Article
Head Impact Exposure in Youth and Collegiate American Football
The relationship between head impact and subsequent brain injury for American football players is not well-defined, especially for youth. The objective of this study is to quantify and assess Head Impact Expos...

Open AccessDevelopment of a Concussion Risk Function for a Youth Population Using Head Linear and Rotational Acceleration
Physical differences between youth and adults, which include incomplete myelination, limited neck muscle development, and a higher head-body ratio in the youth population, likely contribute towards the increas...

Estimated Brain Tissue Response Following Impacts Associated With and Without Diagnosed Concussion
Kinematic measurements of head impacts are sensitive to sports concussion, but not highly specific. One potential reason is these measures reflect input conditions only and may have varying degrees of correlat...

Parametric Comparisons of Intracranial Mechanical Responses from Three Validated Finite Element Models of the Human Head
A number of human head finite element (FE) models have been developed from different research groups over the years to study the mechanisms of traumatic brain injury. These models can vary substantially in mod...

Development of a Multimodal Blast Sensor for Measurement of Head Impact and Over-pressurization Exposure
It is estimated that 10–20% of United States soldiers returning from Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) have suffered at least one instance of blast-induced traumatic brain inju...

Maximum Principal Strain and Strain Rate Associated with Concussion Diagnosis Correlates with Changes in Corpus Callosum White Matter Indices
On-field monitoring of head impacts, combined with finite element (FE) biomechanical simulation, allow for predictions of regional strain associated with a diagnosed concussion. However, attempts to correlate ...
