%X 离体脊柱标本三维运动载荷-位移特性的描述是脊柱生物力学研究的基础，如何准确地模拟在体脊柱的载荷与运动情况是脊柱生物力学研究的难点。国内外学者从测试理论与测试工具上都进行了大量的研究。目前脊柱三维运动测试按照控制方法主要分为载荷控制、位移控制和混合控制。基于不同的控制方法，测试工具也在不断的发展与完善之中。总结目前国内外研制的脊柱离体加载装置的工作原理，并分析其主要优缺点，为离体脊柱生物力学加载装置研究提供参考。</br>The description for load-displacement characteristics of in vitro spinal specimens in three-dimensional (3D) motion is the foundation of spinal biomechanical research. How to simulate the load and movement of spine in vivo as accurately as possible is the difficulty of in vitro spinal biomechanical research. Domestic and foreign scholars have carried out extensive research on theories and equipments of spinal biomechanical test. Currently, the spinal 3D motion test is mainly divided into load control, displacement control and hybrid control according to the control method. Based on different control method, the test equipments are also developing and perfecting constantly. The operation principle for current in vitro spinal loading devices are summarized, and their advantages and disadvantages are also analyzed, so as to provide references for the research on in vitro spinal biomechanical loading devices.
