Abstract

A computer simulation was developed in which the cervical spine was modeled as a biomechanically equivalent linkage system. The model was driven by data from in vitro tests of fresh human cadaver spines. The goal of the model was to iteratively determine appropriate rotational stiffness values by comparing the loading vector with that of the experimental data. With a rotational stiffness of 2.0 Nm/deg, the loading vector was 46.7 N compared to an experimental value of 45.7 N for 35 degrees of rotation
