| 中文摘要:实验对象为L1～5的完整腰椎标本,设计了平行光脊柱三维运动测量系统,改进加载方法以更好模拟脊柱推拿手法,设置7个腰椎特定点,将观察图像动态变化输入计算机系统,应用工程系统力学中刚体转移计算理论进行计算,获得腰椎及其后部结构在模拟推拿加载时的三维运动量。根据右旋时完整腰椎的三维运动结果,发现在左侧卧位斜扳时,右侧关节突等构成神经根管壁结构发生定向位移,在各节段可以不同,但其主运动轴位移的结果可直接扩大神经根管,或牵拉,紧张小关节囊韧带和黄韧带而扩大神经根管。 |

| Study on 3-D movement of whole lumbar spine in rotatory chiropractic |
|
| ABSTRACT For the purpose of observing 3-D movement of the whole lumbar spine in rotatory chiropractic, the expeimental specimen from segmental lumbar movement was changed to L1-L5 whole lumbar spine, thereby a parallel spinal 3-D movement measurement system was designed by the authors.The loading method was reormed so as to improve imifation of the chorpractic mameiuer of the spine. Seven definite lumbar spinal points were set and the image developments so observed over these points were inputted into the computer system. Calculation of the quantitative 3-D movement in imitation chiropractic loading of the lumbar spine and it's posterior elements was made by rigidity transform mathematic theory of the mechanics of engineering system. According to the result of 3-D movement of whole lumbar spine in right rotation,we found the rotatory chiropractic applied on left lying position the right facet joint proces that contituted the inner wall of nerve root canal developed directional displacement. Although it may be different in separate individual segment,the displacement in the main movement axis could directly enlarge the nerve root canal,or drawing and tightening the capsule ligament of facet joint and ligament flavium in order to enlarge the nerve root canal. |
