A modeling effort has been undertaken at the Naval Biodynamics Laboratory in New Orleans to determine the cause of atypical responses of the head/neck anatomy of certain volunteer subjects to -x vector direction acceleration profiles. The results appear to indicate that these subjects, who had been previously run in the +y and/or -x+y vector directions, may have learned to exert purposeful control over their head/neck responses in order to lessen the severity of their exposures. Computer simulations appear to verify the theorized explanation that the subjects "locked" their head/neck joints in anticipation of sled firing, and that the joints remained locked during the initial portion of the run until forces and torques incrased to a level which forced their joints to unlock. For the covering abstract of the conference see TRIS 399532. (Author)
