In mathematical modeling of multi-segmented articulating total-human-body, there is no doubt that the shoulder complex plays one of the most important roles. However, proper biomechanical passive resistive force data have been lacking in the literature. This paper presents determination of the three-dimensional passive resistive joint properties beyond the maximal voluntary shoulder complex sinus. A functional expansion with two spherical angular variables in the local joint axis system is proposed to fit the overall restoring force (moment) data. A constant restoring force (moment) contour map as well as a three-dimensional perspective view of the results are presented in a new coordinate system defined in this study. Finally, a statistical data base is established by utilizing the statistical analysis procedures discussed in Part I of this paper.
在多节段人体关节活动的数学建模中，毫无疑问，肩部复合体起着最为重要的作用之一。然而，文献中一直缺乏合适的生物力学被动阻力数据。本文介绍了超出肩部复合体最大自主活动范围的三维被动阻力关节特性的测定方法。提出了一种在局部关节轴系中具有两个球面角变量的函数展开式，以拟合整体恢复力（力矩）数据。在本研究定义的新坐标系中，给出了恒定恢复力（力矩）等高线图以及结果的三维透视图。最后，利用本文第一部分讨论的统计分析程序建立了一个统计数据库。
