Kinematic analysis of the upper extremity has been conducted using a wide variety of techniques, philosophies, and analytic methods. We describe a simple, marker-based three-dimensional video analytic technique that borrows concepts from lower extremity kinematic analysis. A sequential rotation order about orthogonal axes is described, although alternate methods are examined as well. The method has been verified by application to a mechanical model. In certain positions, gimbal lock may occur, and a different sequence of rotational decomposition may be required. Agreement on standardization of technique would assist in the dissemination of upper extremity scientific data.
上肢的运动学分析已经采用了各种各样的技术、理念和分析方法。我们描述了一种简单的、基于标记的三维视频分析技术，该技术借鉴了下肢运动学分析的概念。描述了一种围绕正交轴的顺序旋转顺序，不过也研究了其他方法。该方法已通过应用于机械模型得到验证。在某些位置可能会出现万向节锁，可能需要不同的旋转分解顺序。技术标准化方面的共识将有助于上肢科学数据的传播。
