- W2181244249 abstract "A review of the current medical and engineering literature provides sufficient understanding of head injury to direct meaningful research. Although many mechanisms have been proposed for the injurious effects of head impact, including pressure gradients and cavitation, relative motion between brain and skull, and brain tissue shear, are implicated as the primary mechanisms of severe vascular damage in closed head impact injury. Current methods to evaluate head impact response involve an incomplete evaluation of dummy head dynamics and an inadequate analysis of the brain response during impact. Fruitful areas of research should emphasize a more complete evaluation of three dimensional translational and rotational motion of the dummy head during impacts associated with serious head injury. The accurate measurement of head dynamics will allow a more realistic analysis of the potential for brain injury at the known sites of primary vascular damage. The analysis procedure could rely on an advanced finite element model of the skull and brain; and, it could predict relative motion between brain and skull, and shear strains in the brain. Although the research would emphasize vascular damage as an endpoint, it is important to develop information on the mechanisms of neural injury causing prolonged unconsciousness and coma. The mechanism of neural damage is probably not identical to that for vascular injury, and a clearer understanding of the biological factors involved in neural trauma would eventually enable meaningful biomechanics research. Due to the significance of head injury as a source of critical, fatal and disabling injury in motor vehicle crashes, attention should be given to research which will evaluate current techniques and develop new procedures to evaluate head injury potential and to assess the benefits of safety technologies." @default.
