项目摘要
The shoulder complex is composed of the scapula, clavicle and humerus. shoulder motion is attained by cooperation of these elements. In order to analyse the shoulder complex mechanism, we carried out following experiments.1)Measurement of motion of the scapula and humerus and EMGUsing a magnetic sensor system(3 SPACE). we measured three dimensional motion of the scapula and humerus in elevation in the sagittal, scapular and frontal plane.We measured Euler angles of the scapula(scapulothoracic angle)and humerus and excursion of the scapula with respect to the reference coordinte attached to the trunk. And we calculated relative Euler angles between the scapula and humerus(gleno humeral angle).The ratio of glenohumeral to scapulothoracic angle during elevation was not constant as reported so far. Instead this ratio varied considerably. Motion pattern of abduction was different from that of other elevation. The abduction proved to be difficult motion from a viewpoint of biomechanics. In accordance with this, ranges of abduction of abnormal shoulders were considerably small.2)Experiment of pitchingUsing 3-D angles of the humerus with respect to the trunk, it was possible to discriminate four phases of pitching. Motion pattern of skilled pitching was markedly different from that of unskilled pitching, especially in the rotation of the humerus and electromyographies.3)Experiment with the shoulders of cadaversFrom experiments of maximum circumduction of cadaver specimens, it was found that there exists linear relationship between the range of motion and the rotation of the humerus. This means restriction of rotation of the humerus causes decrease of the range of motion.
肩复合体由肩胛骨、锁骨和肱骨组成。肩部运动通过这些元件的合作来实现。为了分析肩关节的复杂机制,我们进行了以下实验:1)利用磁传感器系统(3SPACE)测量肩胛骨和肱骨的运动和肌电。测量肩胛骨和肱骨在矢状面、肩胛骨面和额状面上的三维运动,测量肩胛骨和肱骨的欧拉角以及肩胛骨相对于躯干坐标的位移。并计算了肩胛骨与肱骨之间的相对欧拉角(盂肱角)。相反,这一比例变化很大。外展位的运动规律与其他体位不同。从生物力学的角度来看,外展被证明是困难的运动。根据这一点,异常肩关节的外展范围相当小。2)俯仰实验利用肱骨相对于躯干的三维角度,可以区分俯仰的四个阶段。熟练投球与非熟练投球的运动模式有明显不同,尤其是在肱骨的旋转和肌电图方面。3)尸体肩部实验通过尸体标本的最大旋转实验,发现肱骨的旋转与运动范围之间存在线性关系。这意味着肱骨旋转的限制会导致活动范围的减少。
