This paper is an extension of the previous work by Wismans et al. A detailed analysis of the high-speed films revealed that the volunteer first thoracic vertebral body (T1) instrumentation mount was not firmly mounted to the spine. In the present analysis a T1 correction is applied to the experiments used in the previous analyses. A description of the correction methodology is presented. The objective of the present study is: (1) to correct for the errors in the T1 rotations; and (2) to develop a set of new performance requirements which are expressed relative to a rotated T1 coordinate system. New requirements are presented and compared with previous analyses. Additionally, the dynamic response of the hybrid III dummy neck is evaluated on the basis of the new performance requirements.
