摘要:


文题释义:

生物力学:生物力学是运用力学的观点、方法和理论对生物体结构和功能进行研究的生物物理学分支。生物力学通过研究生物体不同层次的应力与应变、运动、流动和生长的关系,进而解决与医学、生理学相关的力学问题。根据研究对象的不同,生物力学可分为固体生物力学、流体生物力学和运动生物力学等。
有限元法:有限元法的原理是将复杂对象划分为有限数量的小单元,不同的单元类型设置不同的材料属性,这些小单元之间相互连接,构建有限元模型替换原本的复杂对象。通过对有限元模型进行力学分析可以得到其内外结构在外力作用下的位移、应力和应变情况。有限元法已经成为计算机分析复杂结构和构件特征的有力工具。

背景:脊柱推拿手法作为脊柱相关疾病疗效显著的物理治疗手段,被国内外学者广泛应用并逐渐向规范化和系统化发展,其作用机制及安全性一直是医疗群体的关注热点。三维有限元法是一种对人体力学行为进行数值模拟的有效工具,通过技术分析以明确手法对脊柱结构的生物力学效应,其具有一定的研究价值及临床意义。
目的:综述三维有限元法的发展历程及其在颈椎、胸腰椎、腰椎推拿手法生物力学研究中的分析流程和应用概况。 
方法:由第一作者以“finite element,biomechanics,spine,cervical vertebrae,thoracolumbar,lumbar vertebra,manipulation”为英文检索词,应用计算机在PubMed及Web of Science数据库检索从建库至2022年4月为止的相关文献共495篇;以“有限元分析、脊柱、颈椎、胸腰椎、腰椎、推拿、手法、生物力学”为中文检索词,应用计算机在中国知网、万方及维普数据库检索从建库至2022年4月的相关文献共593篇,根据纳入标准选择其中的80篇进行综述。
结果与结论:①通过三维有限元法对推拿手法作用下的脊柱结构进行应力应变分析,可获得模型各部件的应力值和位移值,客观、直观和准确地反映椎体、椎间盘、韧带、肌肉、血管和神经等部件的力学效应状况,为阐释脊柱推拿手法的作用机制、提高手法操作的安全性和有效性提供有力的证据依靠,极大地推进了临床推拿手法技术的发展,拥有良好的发展潜力。②目前三维有限元法在脊柱推拿手法生物力学研究上已取得重要进展,脊柱模型的椎旁软组织部件模拟不断完善,颈椎和腰椎推拿手法的基础研究不断深入,推拿手法的生物力学分析由固体力学发展至流体力学。③但现阶段应用中仍存在着脊柱模型影像学来源和各部件材料设定数据的代表性不足,脊柱推拿手法的模拟和加载过于简单,很多胸椎推拿手法的基础研究未能开展等问题,未来研究者需要进一步完善和改进,使三维有限元法更好地满足脊柱推拿手法临床和科研的需求。

Abstract: BACKGROUND: As a physical therapy method with remarkable curative effect for spinal diseases, spinal manipulation has been widely used by scholars at home and abroad and gradually developed into standardization and systematization. Its mechanism of action and safety have always been the focus of medical attention. Three-dimensional finite element method is an effective tool for numerical simulation of human mechanical behavior. It has certain research value and clinical significance to clarify the biomechanical effect of manipulation on spinal structure through technical analysis.  
OBJECTIVE: To review the development of three-dimensional finite element method and its application in biomechanics of cervical, thoracolumbar and lumbar manipulations.
METHODS: The first author used “finite element, biomechanics, spine, cervical vertebrae, thoracolumbar, lumbar vertebra, manipulation” as English search terms, and used computer to search PubMed and Web of Science databases from establishment to April 2022. There were a total of 495 related articles. The “finite element analysis, spine, cervical spine, thoracic and lumbar spine, lumbar spine, massage, manipulation, biomechanics” were used as the Chinese search terms. A total of 593 related articles from the establishment of the database to April 2022 were checked in CNKI, Wanfang, and VIP databases using computers, and 80 of them were selected for review according to the inclusion criteria.  
RESULTS AND CONCLUSION: (1) Through the three-dimensional finite element method to analyze the stress and strain of the spine structure under the action of massage manipulation, the stress value and displacement value of each part of the model can be obtained, which can objectively, intuitively and accurately reflect the vertebral body, intervertebral disc, ligament, muscle, blood vessel, nerve, etc. The mechanical effect status of the components provides strong evidence for explaining the mechanism of spinal manipulation, improving the safety and effectiveness of manipulation, greatly promoting the development of clinical manipulation techniques, and has a good development potential. (2) The three-dimensional finite element method has made an important progress in the study of the biomechanics of spinal manipulation. The simulation of paravertebral soft tissue components of the spinal model has been continuously improved. The basic research of cervical and lumbar massage manipulations has continued to deepen, and the biomechanical analysis of massage manipulations has developed from solid mechanics to fluid mechanics. (3) However, there are still problems such as insufficient representation of the imaging sources of the spine model and the material setting data of each component in the current application. The simulation and loading of spinal manipulation manipulations are too simple, and many basic researches on thoracic manipulation manipulations have not been carried out. The researchers need to further improve, so that the three-dimensional finite element method can better meet the needs of clinical and scientific research of spinal manipulation.

Key words: three-dimensional simulation model, finite element analysis, spine, cervical spine, thoracolumbar spine, lumbar spine, massage, manipulation, biomechanics, review
