Accurately replicating the in-vivo loads of the spine is a critical aspect of in-vitro spine testing, but the complexity of this structure renders this challenging. The design and control capabilities of multi-axis spine systems vary considerably, and though recommendations have been made [1, 2], standardized in-vitro methods have not yet been established. As such, it is often difficult to compare different biomechanical studies . The aim of this study was to use international standards [4, 5], and spine testing recommendations [1-3] to develop a standardized protocol for the evaluation of different multi-axis spinal test systems. The protocol was implemented on three six-axis spine systems, and the data used to establish stiffness and phase angle limits. [...]
