In recent years, anatomically accurate dummies were developed to produce a more biofidelic response to rear impacts. The detailed dummy geometry permits more comprehensive kinematic validation, which is typically accomplished through response corridors developed using human volunteers and cadavers. In the present investigation, ten intact head-neck cadaver specimens were subjected to 1.8 and 2.6 m/s rear impacts. Response corridors were developed for overall head to T1 angulation, head retraction, and segmental angulations from C2-C3 through C6-C7 levels. The corridors were developed to emphasize the detailed validation of dummy response during initial stages of whiplash loading. Experiments using human volunteers and cadavers are typically used. The kinematic responses of intact head-neck complexes were mass-scaled to develop mean and standard deviation response corridors for segmental and head to T1 angulations and head retraction relative to T1 at two impact velocities. Development of the corridors focused on the proposed whiplash injury mechanism (head retraction and cervical S-curvature) and time at which injury most likely occurs. These response corridors were developed to validate existing rear impact dummies (BioRBD, RID, TRJJD) and aid in the development of new dummies.
