The authors describe a new method for measuring the flexibility of the shoulder. They have designed a device consisting of two electrical goniometers to measure the horizontal and the vertical position of the humerus. A computer registers these signals, calculates the region of mobility as a sperical segment centered to the shoulder joint (caput humeri). This region is displayed in a map, called arthrogram. Slightly modified, the arthrograph measures the rotation of the humerus and depicts the rotation angle into the map, at the site of the measurement. First results are reported. The procedure is reproducible with an error less than 5 degrees. Arthrograms of sound persons are compared to those of different pathological symptoms. Arthrograms show more information than single angular values. They can be viewed easily, e.g. to control the success of a treatment.
作者描述了一种测量肩部灵活性的新方法。他们设计了一种由两个电子测角仪组成的装置，用于测量肱骨的水平和垂直位置。计算机记录这些信号，将活动区域计算为以肩关节（肱骨头）为中心的球形部分。该区域显示在一张称为关节造影图的地图上。经过稍加修改，关节造影仪可测量肱骨的旋转，并在测量部位将旋转角度描绘到地图中。报告了初步结果。该程序具有可重复性，误差小于5度。将健康人的关节造影图与有不同病理症状者的进行比较。关节造影图显示的信息比单个角度值更多。它们易于查看，例如用于控制治疗的效果。
