Head-first impacts with an aligned cervical spine cause some of the most severe types of injuries due to the risk of fractures and associated spinal cord injury. Sports, such as football, mountain biking and horseback riding, contribute to the incidence of spinal cord injury but there is potential to reduce the risk of these injuries through a helm...

Injury
Since their introduction to USA markets in the late 20th century, all-terrain vehicles (ATVs) have been a significant source of trauma. Many paediatric studies have demonstrated the disproportionate rate in which minors are affected by ATV-related trauma, but no studies have been performed on a large sample size spanning all age and geographic rang...

Forty-eight helmets were discovered in the Villanovan necropoleis in Verucchio (Italy). Due to this large number of finds and the typological variety of the helmets, Verucchio can be considered a privileged observatory for the study of this class of materials. Helmets were in fact typical products of metallurgical workmanship. It is known that the ...

Egocentric distance estimation has been shown to depend on wearing safety gear, which promotes compensatory behavior, and on target type, which regulates fight-or-flight responses. We hypothesized that the two factors interact, possibly in asymmetric fashion, and set out to uncover the limits of this interaction in a perceptual task where individua...

Helmet design and development are an important tool to help mitigate the severity and frequency of head and brain injury in sport and everyday life. Helmet assessment protocols and standards often use the Hybrid III neckform as part of the impacting equipment even though it has a biased response that can affect the results. This research presents a...

Objective Many survivors of acute respiratory distress syndrome (ARDS) have poor long term outcomes possibly due to supportive care practices during invasive mechanical ventilation. Helmet noninvasive ventilation (NIV) in ARDS may reduce intubation rates; however it is unknown if avoiding intubation with helmet NIV alters the consequences of surviv...

With the development of high-performance fighters, the function of pilot helmets is also constantly upgrading, and helmet-mounted display (HMD) has become a future development trend. To solve the inter-restriction between the eye position control and the pressure comfort under high overloads of pilot helmets, this paper optimizes the helmet design ...

Recently studies have assessed the ability of helmets to reduce peak linear and rotational acceleration for women's lacrosse head impacts. However, such measures have had low correlation with injury. Maximum principal strain interprets loading curves which provide better injury prediction than peak linear and rotational acceleration, especially in ...

Concussions are among the most common injuries sustained by ice hockey goaltenders and can result from collisions, falls and puck impacts. However, ice hockey goaltender helmet certification standards solely involve drop tests to a rigid surface. This study examined how the design characteristics of different ice hockey goaltender helmets affect he...

Six synthetic head models wearing ballistic protective helmets were used to recreate two military combat-related shooting incidents (three per incident, designated ‘Incident 1’ and ‘Incident 2’). Data on the events including engagement distances, weapon and ammunition types was collated by the Defence Science and Technology Laboratory. The models w...
