An experimental investigation was performed to determine the segmental cervical spine kinematics in rear impact acceleration. Segmental motions were analyzed at the time of maximum S-curve for 10 isolated head-neck specimens (5 male, 5 female). Females experienced greater segmental angles at each level of the spine for all input velocities. Statistically significant gender differences were obtained for levels C2-C3, C5-C6, and C6-C7. Motions were statistically dependent upon input velocity for C4 to C7 segments. Results of this study provide a biomechanical basis for the differing rates of reported whiplash injuries between males and females.
