设计并测试了一种研究人体肩部节律的方法，即肩部各组成部分运动之间的相互作用。该方法是基于数值评估的低剂量的roentgenstereophotogrammetric电影的主题配备了辐射密集的arteritations在骨头。该方法的评价表明，它可以用于确定运动模式，所采用的插值技术可以用来模拟实际上没有在实验室中进行的运动。以前对肩节律的研究很差，发表的量化结果仅涉及一个平面。我们的结果与以前的调查运动模式。通过这种方法，我们发现，骨骼的绝对位置在个体之间变化很大，而骨骼在运动过程中的相对位移表现出相似性。特别是结果表明，在正常情况下，个人的节奏是非常稳定的，不敏感的小手负荷。
A method to investigate the rhythm of the human shoulder, i.e. the interplay between the motion of constituent parts of the shoulder, has been devised and tested. The method is based upon numerical evaluation of low dose roentgenstereophotogrammetric motion pictures of subjects equipped with radiation dense implantations in the bones. Evaluation of the method shows that it may be used in determining motion patterns and that the employed interpolation techniques can be used to simulate motions not actually performed in the laboratory. The shoulder rhythm has been previously poorly investigated and quantified results published pertain to one plane only. Our results on motion patterns correlate with previous investigations. With this method, we show that the absolute position of the bones varies significantly between individuals while the relative displacement of the bones during motion exhibit similarities. In particular the results show that, under normal conditions, the individual rhythm is very stable and insensitive to small hand-loads.
