An investigation was made of the effects of acceleration of the approximate center of mass of the head with respect to the body eliminating the effects of deformations of the head as produced by a direct blow. The development of a mechanical device with w...

The effect of rotational and translational acceleration on the brain was studied using two different mathematical analyses. A mathematical model of a head subjected to an angular acceleration was developed in which the brain was treated as a viscoelastic ...

... Z axis Neck Torque X, Y axes ... Head Unear Acceleration Head linear accelerations were used to calculate GSI and HIC values for brain injury. ...

The report describes the results of a three year program in experimental head injury. During this period a highly successful head accelerating device was evolved. Major features of this machine include the application of a reproducible non-deforming stimu...

The blast wave that is generated from the detonation of an anti- personnel mine can induce significant accelerative loading to the head of a deminer, when the wave collides with the victim. The injury potential posed by the resulting head acceleration in ...

The use of the rhesus as a human surrogate in studying head-neck injury due to impact acceleration depends of the similarity of human and rhesus head-neck kinematic and dynamic responses. This report addresses the question of -X rhesus head-neck kinematic...

Abusive head injuries are among the most common causes of serious and lethal injuries in children. These injuries may result from impact or shaking or a combination of these mechanisms. These mechanisms cause the child's head to undergo acceleration-deceleration movements ...

Although head-mounted technologies have the potential to significantly enhance pilot performance, they increase the mass of the helmet considerably and may increase the risk of cervical injury during emergency ejection. The lack of adequate head restraint...

Most cranio-cerebral injuries seen in the emergency department are caused by acceleration-deceleration or a direct impact mechanism. Compression or crush injury to the head is less commonly seen. A crush injury occurs when a body part is subjected a degree of force or pressure, usually after ...

Non-accidental head trauma in infants is the leading cause of infant death from injury. Clinical features that suggest head trauma (also known as shaken baby syndrome or shaken impact syndrome) include the triad consisting of retinal hemorrhage, subdural, and/or subarachnoid hemorrhage in an infant with little signs of external trauma. ...

The Federal Motor Vehicle Safety Standard 571.201 discusses occupant protection with interior impacts of vehicles. Rule making by the National Highway Traffic Safety Administration (NHTSA) has identified padding for potential injury reduction in vehicles. In these studies, head injury mitigation with padding on vehicular roll bars and ...

This report considers the application of an impact acceleration injury prediction model to observed data from a set of twenty-eight -G sub x accelerator runs involving subhuman primates (Rhesus monkeys) with securely restrained torso and unrestrained head...

In a rear-end crash, if an occupant's head is unsupported it lags behind as the torso is accelerated forward. This causes the neck to change shape, first taking an s-shape and then bending backward in a 'whiplash' motion. This sudden differential movement of the head and torso can cause 'whiplash' injuries to the ...

This paper starts from the concept that acceleration injury of the cervical spine is caused by hypertranslation of the head with respect to the trunk, and not by hyperflexion or hyperextension. In this second part of the paper literature describing craniovertebral junction damage after acceleration ...

Impacts and closed head injuries resulting from transportation accidents are not well-defined scientifically, because of the scarcity of valid data. Test animals, anthropometric dummies and human cadavers are not sufficient representations to permit corre...

Forty intact, moist, embalmed, human cadavers were dropped with their heads striking at various locations against several surfaces. Parameters measured and computed include drop height, velocity, force, head accelerations, pulse duration, injury indices, ...

The recording and subsequent analysis of evoked potential activity has proven useful for the evaluation of neural dysfunction resulting from impact acceleration injury involving the head and neck. In animal impact acceleration experiments involving Rhesus...

Angular accelerations are considered responsible for certain types of common brain injuries. It is therefore of great importance that they can be measured in conjunction with testing of protective headgear. Angular accelerometers presently on the market a...

Head injury is a common finding for infants and young children involved in automobile accidents. Although the child restraint seats have increased the level of safety for the pediatric population, skull fracture and/or brain injury occur during the interaction between the child's head and interior of the car seats ...

Abusive head injury, characterized by repeated acceleration-deceleration forces, is associated with retinal hemorrhages as demonstrated in many clinical and postmortem studies. The theory that vitreoretinal traction is the major factor in the pathogenesis of retinal hemorrhages is presently the most widely accepted explanation based on ...

Head injuries can range from a minor bump on the head to a devastating brain injury. Learning to recognize a serious head injury, and implementing basic first aid, can make ...

The objective of the present study is to synthesize and investigate using the same set of sixty-one real-world accidents the human head injury prediction capability of the head injury criterion (HIC) and the head impact power (HIP) based criterion as well as the injury ...
