The exact nature of the mechanisms at work during movement of the human spine are not well understood, nor well defined. The spine supports the torso against loads and allows freedom of motion, within physiologic limits, at the same time. A great deal of information characterizing various attributes of the spine is available. Research has provided values for flexural stiffness, axial compliance, range of motion under various loading modalities, and considerably more. This study will focus not on isolated topics, but rather serve as a broad introduction to the behavior of the spine as a whole.
人类脊柱运动过程中起作用的机制的确切性质尚未得到充分理解，也未得到明确界定。脊柱支撑着躯干以抵抗负荷，同时在生理限度内允许自由运动。有大量描述脊柱各种特性的信息。研究已经给出了弯曲刚度、轴向顺应性、各种加载方式下的运动范围等数值，还有更多信息。本研究将不聚焦于孤立的主题，而是作为对脊柱整体行为的广泛介绍。
