Rotational (Rxyz) and translational (Tx, Ty, Tz) stiffness values for the model components [13,15]. Stiffness values are relative (between adjacent bodies). The global coordinate system was implemented with the positive x-axis (medial/lateral) to the left of the model, the positive y-axis (superior/inferior) facing upwards, and the positive z-axis (anterior/posterior) facing forward.
