In order to analyze shoulder joint movements, the authors use a ZEBRIS CMS-HS ultrasound-based movement analysis system. In essence, the measurement involves the determination of the spatial position of the 16 anatomical points, which are specified on the basis of the coordinates of ultrasound-based triplets positioned on the upper limb, the scapula, and the thorax; their spatial position is measured in the course of motion. Kinematic characteristics of 74 shoulder joints of 50 healthy persons were identified during elevation in the plane of the scapula. Kinematic characteristics of motion were identified by scapulothoracic, glenohumeral, and humeral elevation angles; range of angles; scapulothoracis and glenohumeral rhythm; scapulothoracic, glenohumeral, and scapuloglenoid ratios; and the relative displacement between the rotation centers of the humerus and the scapula. Motion of the humerus and the scapula relative to each other was characterized by their rotation as well as the relative displacement between the rotation centers of scapula and humerus. The biomechanical model of the shoulder joint during elevation can be described by analyzing the results of the measurements performed.
为了分析肩关节运动，作者使用了基于ZEBRIS CMS-HS超声的运动分析系统。实质上，测量涉及确定16个解剖点的空间位置，这些点是根据位于上肢、肩胛骨和胸部的基于超声的三联体的坐标指定的；它们的空间位置在运动过程中进行测量。在肩胛骨平面上抬高过程中，对50名健康人的74个肩关节的运动学特征进行了识别。通过肩胛胸壁、盂肱和肱骨抬高角度；角度范围；肩胛胸壁和盂肱节律；肩胛胸壁、盂肱和肩胛盂比例；以及肱骨和肩胛骨旋转中心之间的相对位移来识别运动的运动学特征。肱骨和肩胛骨相对于彼此的运动以它们的旋转以及肩胛骨和肱骨旋转中心之间的相对位移为特征。通过分析所进行测量的结果，可以描述抬高过程中肩关节的生物力学模型。
