Recently, several cases of mild traumatic brain injury to American professional football players have been reconstructed using instrumented Hybrid III anthropomorphic test dummies ATDs. The translational and rotational acceleration responses of injured and uninjured players' heads have been documented. The acceleration data have been processed according to all current head injury assessment functions including the GSI, HIC and GAMBIT among others. A new hypothesis is propounded that the… Expand
A new biomechanical assessment of mild traumatic brain injury. Part 2: Results and conclusions
TLDR
A new approach employing the maximum value of the global rate of energy dissipation has proven to provide the best correlation between concussion probability and head kinematics, providing a basis for a new HIC function, the Head Impact Power (HIP). Expand
Verification of biomechanical methods employed in a comprehensive study of mild traumatic brain injury and the effectiveness of American football helmets.
TLDR
The potential error in the relative impact velocity between colliding heads could be as high as 11%, and was found to be the largest error source in the sequence of techniques to reconstruct the game impacts. Expand
A Review of Head Injury and Finite Element Head Models
Head injury, being one of the main causes of death or permanent disability in everyday life, continues to remain as a major health problem with significant socioeconomic costs. Therefore, there is aExpand
Rotational Head Kinematics in Football Impacts: An Injury Risk Function for Concussion
TLDR
Characterizing the rotational kinematics of the head associated with concussive impacts using a large head acceleration dataset collected from human subjects provides critical insight into injury mechanisms, human tolerance to mechanical stimuli, and injury prevention techniques. Expand
Predictors for traumatic brain injuries evaluated through accident reconstructions.
TLDR
It was found that a simple linear combination of peak change in rotational velocity and HIC showed a high correlation with the maximum principal strain in the brain, in addition to being a significant predictor of injury. Expand

TLDR
This review paper gives a thorough overview of the work carried out by the scientific community in the field of impact biomechanics about head injuries sustained during sports activity and presents the head injury criteria and their respective thresholds. Expand
Head injury prediction capability of the HIC, HIP, SIMon and ULP criteria.
TLDR
It is clearly shown that moderate and severe neurological injuries can only be distinguished with a criterion that is computed using intracranial variables and not with the sole global head acceleration. Expand
Kinematics simulation and head injury analysis for rollovers using MADYMO
This study demonstrates the applicability of occupant kinematics simulation and head injury analysis with MADYMO simulation for rollovers. Two real-world rollover crashes, together with an SAEJ2114Expand
Sensitivity analysis of muscle properties and impact parameters on head injury risk in American football.
TLDR
The results of this study indicate that active neck muscles have a statistically significant effect on head injury metrics, and a comprehensive approach to athlete training protocols is recommended, including exercises aimed at increasing eccentric muscle strength and preparation for impacts.

HEAD IMPACT SEVERITY MEASURES FOR EVALUATING MILD TRAUMATIC BRAIN INJURY RISK EXPOSURE
TLDR
This study is the first to the authors' knowledge to quantify improvements in the sensitivity of a biomechanical measure to incidence of concussion when impact location is considered and develops a novel measure of head impact severity combining these measures into a single score that better predicts the incidence of concussions.
