Quasi-linear modeling of the viscoelastic responses of the human cervical spine in torsion
The dynamic torsional responses of the human cadaver cervical spine were measured in vitro. The quasi-linear formulation of time dependent behavior was used to describe these structural responses. The resulting model showed high predictive ability, reaching the 99% confidence level for 36 of 36 tests (r = 0.9288). These results and the results of earlier investigations suggest that the quasi-linear model should be considered as a model of generalized spinal kinetics.
