THE EFFECT OF MUSCLE ACTIVATION ON NECK RESPONSE

This paper describes an anatomically detailed finite element (FI) model with active muscles that follow the spinal curvature developed and validated against frontal and side impacts with good correlation. Muscle synergism was also implemented in the model with good results. The model was used for injury prediction of soft tissues using tissue specific failure criteria during dynamic loading. Muscle activation was found to decrease the risk of injury to the spinal ligaments. Activation was found to protect the upper cervical spine in frontal impacts where injury was presented with a passive muscle model. In lateral impacts, muscle activation decreased ligament strain at all spinal levels. The results clearly demonstrate that muscle activation decreases the risk for ligament injury, and that the spinal levels that are protected varies with the external loading that the neck is subjected to.
