A finite element study on the effect of initial head-neck posture on neck injury risk in frontal collisions

Non-neutral head-neck postures during frontal collisions increase cervical biomechanical loading compared with the neutral posture. NIC and Nkm exceeded their injury thresholds in all non-neutral postures, while Nij remained below its threshold but exhibited a similar trend. Among the postures studied, extension and high axial rotation resulted in the highest loading on cervical soft tissues. Maintaining a neutral posture may help reduce cervical injury risk for front-seat passengers.

Abstract

Non-neutral head-neck postures during frontal collisions increase cervical biomechanical loading compared with the neutral posture. NIC and Nkm exceeded their injury thresholds in all non-neutral postures, while Nij remained below its threshold but exhibited a similar trend. Among the postures studied, extension and high axial rotation resulted in the highest loading on cervical soft tissues. Maintaining a neutral posture may help reduce cervical injury risk for front-seat passengers.
