Outcome Measures
Primary Outcomes (1)
Verification of the model
In this study, the pure torque of 2.0Nm was applied to the upper surface of C2 vertebral body along the 1, 2 and 3 coordinates according to the right hand helical rule to generate the corresponding pure torque in the sagittal plane, coronal plane and axial plane, and to simulate the cervical spine flexion and extension, lateral bending and left-right rotation in real life
Through study completion, an average of 1 year
