Response corridors of the human head-neck complex in rear impact.

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.
