Positions of the shoulder joint are commonly described in terms of degrees of humeral elevation in the principal planes. This approach is inadequate for an accurate and unambiguous description of functional arm movements that are not confined to these planes. In this paper, a general unambiguous method for describing shoulder positions is adopted and visualized in globe graphs. This facilitates the use and interpretation of the method in clinical practice. To illustrate this globe system of description, a healthy subject participated in the experiments. The shoulder position is described for several functional and standardized tasks for the upper limb with three angles: (1) the angle of the plane of elevation, (2) the angle of elevation within the plane of elevation, and (3) the angle of axial rotation. With these parameters, the position of the upper arm can be visualized as a position on a "globe" about the shoulderjoint. Although not perfect, the globe system provides the most unambiguous description of functional thoraco-humeral positions, which is easy to apply in clinical practice.
肩关节的位置通常根据肱骨在主要平面上的抬高角度来描述。这种方法不足以准确且明确地描述不限于这些平面的功能性手臂运动。在本文中，采用了一种通用的、明确的描述肩部位置的方法，并在球体图中进行可视化。这便于在临床实践中使用和解释该方法。为了说明这种球体描述系统，一名健康受试者参与了实验。通过三个角度描述了上肢的几个功能性和标准化任务的肩部位置：（1）抬高平面的角度，（2）抬高平面内的抬高角度，以及（3）轴向旋转角度。利用这些参数，上臂的位置可以可视化为肩关节周围“球体”上的一个位置。尽管并不完美，但球体系统提供了对功能性胸肱位置最明确的描述，易于在临床实践中应用。
