颈椎侧扳法操作轨迹的动力学和运动学分析

Dynamics and Kinematics Parameters of Cervical-Lateral Realignment Manipulation

目的:对颈椎侧扳法进行客观化描述,为手法操作规律性研究提供数据支持。方法:选临床工作20年以上的推拿医生对22名健康志愿者进行颈椎侧扳法操作,应用动态捕捉系统和测力台采集动力学和运动学数据。结果:颈椎侧扳法的侧扳定位角度约34.60°,侧扳极限角度约39.13°,侧扳瞬间角度差约4.51°,扳动时间约0.22 s,角速度约21.15°/s;在侧扳瞬间,施术者足底合力减少了约11.67 kg,受试者足底合力增加了约10.10 kg。结论:动力学和运动学参数为颈椎侧扳法的规范化操作提供了参考依据。

Objective： To make the objective description of the cervical-lateral realignment manipulation,providing the data support for standard manipulation therapy. Method： One clinical doctor who worked for more than 20 years of massage applied cervical-lateral realignment manipulation in 22 healthy volunteers,dynamics and kinematics data was collected by Motion-Capture-System and Force Platform. Results： The positioning angle of cervical-lateral realignment manipulation positioning was about 34. 60°and the ultimate angle was about 39. 13°. The angular variation in instantaneous realignment was about 4. 51 rad / s and the instantaneous realignment moment was 0. 22 s. The angular velocity was about 21. 15 rad / s. In instantaneous realignment,the resultant force of performer reduced 11. 67 kg and the resultant force of subject increased 10. 10 kg. Conclusion： The dynamics and kinematics parameter provides the data support for standard manipulation of cervical-lateral realignment.
