Abstract：BACKGROUND:With the gradual development of spine fusion surgery and artificial disc implant surgery, researchers have studied the characteristics of spine in various ways using many kinds of medical equipment in recent years. Biomechanical studies of more realistic simulation of human physiological environment and human movement are needed. <br> OBJECTIVE:To review domestic and foreign documents and sum up the advantage and disadvantage of spinal biomechanics research methods from the aspects of measurement subjects and measurement <br> methods. <br> METHODS:The PubMed database, Web of Science database, Springer database and CNKI database were searched with key words of“biomechanical and (properties or study or evaluation), spinal biomechanics, spine mechanical test, spine and (kinematics or motion)”in English and Chinese respectively. Articles related to mechanics kinematics and dynamics of spine were included. Researches in recent five years and classic literature in this field were col ected, and the repetitive studies were excluded. A total of 38 articles were discussed. <br> RESULTS AND CONCLUSION:Researchers have studied the spinal mechanical properties of a plurality of structural details and the movement form in basic conditions simulating human motion in recent 30 years. Many spinal properties about mechanics and dynamics were mastered. There is need for more in-depth understanding of spinal properties in future, such as the damping characteristics of disc mechanics and coupling movement of spinal kinematics, which would be helpful in designing treatment products and curing spinal disease.
