【摘要】：目的寻找不同类型肩胛骨动力障碍肩胛带肌活动的表面肌电特征,探究不同类型肩胛骨动力障碍的异常肩胛骨动力学,以便进一步理解肩胛骨动力障碍出现的规律和寻找更有效的方法预防、治疗肩关节疾病。方法选取11例双侧肩胛骨对称的健康成年人(对照组)与29例肩胛骨动力障碍患者(肩胛骨动力障碍组),其中肩胛骨动力障碍组包括根据Kibler分型的I型组、II型组、III型组,分别在肩关节前屈、外展时进行肩胛带肌活动的sEMG测试,将对照组所测试肌肉左右两侧最大肌电活动差值的绝对值|α|作为参考值,再观察I型、II型、III型组中(患侧与健侧对比),各测试肌肉活动增强与减弱的例数情况。结果当肩关节前屈时,I型、II型、III型组患侧斜方肌上束及II型组患侧岗下肌活动均较健侧增强(P0.05),II型组患侧斜方肌中束、III型组三角肌前束活动均较健侧减弱(P0.05)。当肩关节外展时,I型组患侧斜方肌下束、前锯肌、三角肌前束,II型组患侧斜方肌上、中束,三角肌前、后束以及III型组三角肌前束活动均较健侧减弱(P0.05),III型组患侧斜方肌上束活动较健侧增强(P0.05)。结论I型肩胛骨动力障碍,肩胛骨内侧缘下部或肩胛下角向背侧突出,与下斜方肌、前锯肌的活动减弱相关;II型肩胛骨动力障碍,肩胛骨内侧缘全部向背侧突出,与中、下斜方肌活动减弱相关;III型肩胛骨动力障碍,肩胛骨上部上移,与上斜方肌活动增强相关。其次,肩胛骨动力障碍可能还与三角肌(前、后束)活动减弱,以及岗下肌活动增强有关。
[Abstract]:Objective to search for the surface electromyography characteristics of different types of scapular motility disorders, and to explore the abnormal scapular dynamics of different types of scapular motility disorders. In order to further understand the occurrence of scapular dyskinesia and to find more effective ways to prevent it. Methods 11 healthy adults with bilateral scapular symmetry (control group) and 29 patients with scapular dyskinesia (scapular dyskinesia group) were selected for treatment of shoulder joint diseases. Type I group, type II group, type III group, The sEMG test of scapular band muscle activity was performed during shoulder flexion and abduction respectively. The absolute value 伪 of the maximal myoelectric activity difference between the left and right muscles of the control group was taken as the reference value. Then we observed the cases of muscle activity enhancement and decrease in type I and type II group (compared with healthy side). Results when the shoulder joint was flexion, the superior bundle of trapezius muscle of the type I group and the inferior muscle of the affected side of the group of type II were also observed. The activity of anterior bundle of deltoid muscle in type III of trapezius muscle was weaker than that of normal side, and the inferior bundle of trapezius muscle of type I group was lower than that of type I group when the shoulder joint was extravasated, and the activity of anterior bundle of deltoid muscle of type III group was lower than that of normal side. The superior trapezius muscle, middle bundle, anterior deltoid muscle, anterior bundle of deltoid muscle and the anterior bundle of deltoid muscle in III group were all weaker than those in normal side. Conclusion the activity of superior bundle of trapezius muscle in type I group is significantly higher than that of normal side. The lower part of the medial margin of the scapular bone or the angle of the subscapular angle protrude to the dorsal side, which is associated with the decreased activity of the inferior trapezius muscle and the anterior serratus muscle. The medial margin of the scapular bone is all protruding to the dorsal side. The decreased activity of inferior trapezius muscle is related to the motor disturbance of scapular bone of type III, the upper part of scapula is moved up, and the activity of superior trapezius muscle is increased. Secondly, the motility of scapular muscle may also be related to the decrease of activity of deltoid muscle (anterior and posterior bundle). And increased activity of the subhilar muscles.
