Abstract

Soft tissues in the cervical spine are known to exhibit strain rate dependent behaviour. The objective of this study is to test the hypothesis that the response of the cervical spine segment to loading in flexion and extension is also rate dependent. Eight cervical spines were sectioned into segments (four segments in total at each level from C2-C3 up to C7-T1) and tested in flexion and extension at one and five hundred degrees per second. The moment-rotation curves were recorded and a paired comparison test was done to identify evidence of increased spine stiffness at higher strain rates. This study found moderate evidence (p<0.05) of increased stiffness for five segments (three in flexion and two in extension).
