N2  - 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 minus X vector direction acceleration profiles. The results appear to indicate that these subjects, who had been previously run in the plus Y and/or minus X plus 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 increased to a level which forced their joints to unlock.     <p>Language: en</p>
