TY - JOUR PY - 1981// TI - Human head tolerance to impact: influence of the jerk (rate of onset of linear acceleration) on the occurrence of brain injuries JO - Proceedings of the International Research Council on the Biomechanics of Injury conference A1 - Walfisch, G. A1 - Fayon, A. A1 - Chamouard, F. A1 - Guillon, C. A1 - Got, C. A1 - Patel, Manish M. A1 - Hureau, Jacques A1 - Tarriere, C. SP - 286 EP - 296 VL - 9 IS - N2 - Acceleration, S.I. and H.I.C. are parameters often considered in relation to head injuries produced by impact. This does not imply that any of these factors considered alone correlates very closely with the severity of the injuries. Do other parameters derived from a gamma (t) pulse, such as the acceleration jerk (d gamma/dt) for the same type of impact loading to the head, have any influence on the extent of injuries? The first objective of this communication is to synthesize experimental data concerning any possible influence of linear acceleration jerk of the head on the extent of the cerebral injuries produced by frontal head impact to freshly perfused and instrumented cadavers. The data obtained from these experiments, combined with that already obtained and published (2)(3)(4)(7) define the relationships between cerebral injuries and HIC values obtained by blows to the head without fracture of the skull.
