三维动态牵伸回旋法干预下冻结肩盂肱关节运动轨迹特征的研究

Research of Movement Locus of Frozen Shoulder Patients' Glenohumeral Joint Under 3D Dynamic Manipulation of Extending Dragging and Rotating

目的:研究三维动态牵伸回旋法干预下冻结肩盂肱关节运动轨迹特征。方法:选择医院骨伤科门诊冻结肩患者5例,采用三维动态牵伸回旋法操作规范进行手法操作,在操作同时运用OptotrakCertus TM运动捕捉系统进行患者肩关节运动数据采集,并观察患者盂肱关节角速度、角加速度,干预下患侧肱骨的旋转角度,以及干预前后患侧上臂位置变化产生的欧拉角分量。结果:外展牵伸法干预下冻结肩盂肱关节的平均角速度、最大角速度、最大角加速度小于跨躯体内收外旋法、跨躯体外展内旋法;患侧肱骨旋转角度均未超过当限制肱骨旋转的韧带处于紧张状态时肱骨旋转可以达到的角度;干预前后患侧上臂位置变化产生的欧拉角分量具有统计学意义(P<0.05)。结论:三维动态牵伸回旋法对冻结肩疗效肯定。

Objective ： To research the movement locus of frozen shoulder patients＇glenohumeral joint under the 3 D dy- namic manipulation of extending, dragging and rotating. Methods ： 5 patients of our hospital, who were diagnosed as fro- zen shoulder,were selected. They were treated with 3D dynamic manipulation of extending,dragging and rotating. And the data of glenhumeral joint＇s angular velocity and angular acceleration was collected, and the rotation angle of humerus and the Eulerian angles component of the upper arm＇s displacement was compared before and after treatment with Optotrak Certus TM. Results ： The extending and dragging manipulation＇s average angular velocity max angular velocity and max an- gular acceleration were more than those of the manipulation of adduction and extorsion and the manipulation of extending and intorsion. The affected side＇s humerus rotation angle didnt reach the angle that the ligament,which restricted the rota- tion of the humerus. There were significant differences on the Eulerian angles component of the upper arm＇s displacement before and after treatment（P 〈 0.05 ）. Conclusion： It is definited that therapeutic effect of treating frozen shoulder wilh the 3D dynamic manipulation of extending, dragging and rotating is obvious.
