Biomechanics of head injury. Toward a theory linking head dynamic motion, brain tissue deformation and neural trauma.

The first step in an accurate interpretation of brain injury risk in dummies involves the measurement of the three- dimensional components of translational and rotational acceleration of the head. In this preliminary study, 2D head dynamics data are used as input to a brain compliance model, which interprets the effect of rapid skull motion as tissue- level deformations of the brain.
