A biplanar videotaping system is used to generate spatial kinematic data of an upper extremity motion. The technique is based upon the characterization of each segment by four points in three-dimensional space using biplanar videotaping and subsequent analysis by computer-aided descriptive geometry. The tests were conducted to determine the system's accuracy and repeatability. The results of the joint kinematics of the test subjects performing a diagonal reaching activity with and without an orthosis (or an assistive device) are presented.
一种双平面录像系统用于生成上肢运动的空间运动学数据。该技术基于通过双平面录像在三维空间中用四个点对每个节段进行特征描述，并随后通过计算机辅助描述几何学进行分析。进行这些测试以确定该系统的准确性和可重复性。给出了测试对象在佩戴和不佩戴矫形器（或辅助装置）情况下进行对角线伸展活动时的关节运动学结果。
