摘要:
目的:了解模拟腰椎关节松动手法和冲击手法下椎间盘应变的变化特征,探讨两种手法对椎间盘应变作用的异同。方法:12具成年男性新鲜尸体腰椎标本(T12～S2)随机分为两组。一组模拟松动手法(n=6):预加载15°,速度3°/s,最大加载角度20°,速度1°/s,L5棘突水平加载9 N.另一组模拟冲击手法(n=6):预加载15°,速度3°/s,最大加载角度20°,冲击速度33°/s,L5棘突水平加载22 N.于标本前面喷涂散斑,采用非接触应变测量系统采集手法全过程的图像。通过ARAMIS软件计算,自动输出Von Mises应变云图。结果:模拟两种手法过程中,腰椎旋转时椎间盘应变逐渐增大,回复过程中椎间盘应变逐渐减小,模拟冲击手法椎间盘应变变化速度更快; 模拟两种手法下无论L4～5还是L5S1椎间盘最大应变差异均无统计学意义(P>0.05); 每种手法下L4～5和L5S1椎间盘最大应变差异无统计学意义(P>0.05)。结论:模拟腰椎关节松动手法和冲击手法下椎间盘最大应变无差异。
Abstract:
Objective:The present study aimed to investigate the differences in human lumbar disc strain during simulated spinal manipulation and spinal mobilization.Methods:A total of 12 adult fresh lumbar spinal specimens(T12～S2)were randomly divided into two groups.The parameters of simulated spinal mobilization were as follows:Preload angle,15°(speed,3°/s); maximum angle,20°(speed,1°/s); and 9 N horizontal force to the L5 spinous process.The parameters of simulated spinal manipulation were as follows:Preload angle,15°(speed,3°/s); impulse angle,20°(impulse speed,33°/s)and 22 N horizontal force to the L5 spinous process.Disc strain was measured by non-contact strain measurement system after speckle was sprained on the anterior surface of the specimens.It was obtained with software ARAMIS,and Von Mises strain nephograms were also output.Results:Strain on discs ascended first and then descended gently during mobilization,while it ascended quickly to peak during manipulation.There was no difference of maximal strain on discs during two techniques(P>0.05).There was no difference of maximal strain between L4～5and L5～S1 discs in either group(P>0.05).Conclusion:There is no difference of maximal strain on discs during simulated mobilization and manipulation.
