This study sought to compare a new head impact-monitoring device, which is not limited to
specific helmet styles, against reference accelerometer measurements. Laboratory …

Bicycle helmets attenuate head impacts using expanded polystyrene (EPS) foam liners. The
EPS density plays a key role in determining the helmet and head response during an …

Understanding the relationship between head mass and neck stiffness during direct head
impacts is especially concerning in youth sports where athletes have higher proportional …

To properly assess sports helmet performance, it is important to select impact conditions that
yield high peak linear or angular accelerations. This was done by measuring the kinematic …

On-field measurement of head impacts has relied on the Head Impact Telemetry (HIT)
System, which uses helmet mounted accelerometers to determine linear and angular head …

Biomechanical headforms are used for helmet certification testing and reconstructing
helmeted head impacts; however, their biofidelity and direct applicability to human head and …

With an increasing focus on long-term consequences of concussive brain injuries, there is a
new emphasis on developing tools that can accurately predict the mechanical response of …

Football helmet certification tests are performed without a facemask attached to the helmet;
however, the facemask is expected to contribute substantially to the structure and dynamics …

Head injuries frequently occur in American football and other contact sports. Uncertainty on
the effects of cervical muscle properties on head injury risk may be due to the limitations of …
