SEGMENTAL CERVICAL SPINE KINEMATICS DUE TO POSTEROANTERIOR IMPACT ACCELERATION

摘要

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.
