In the last two decades, several multi-segmented mathematical models of the total-human-body have appeared in the literature. While these models can handle very sophisticated load-motion situations, their effectiveness depends heavily on the proper biomechanical description and simulation of the major articulating joints of the human body. Among these joints, the most complicated and the least successfully modeled one has been the shoulder complex mainly due to the lack of an appropriate biomechanical data base as well as the anatomical complexity of the shoulder region. In 1984, the senior author and his associates proposed a new kinematic data collection methodology by means of sonic emitters and associated data analysis technique. Based on this data collection methodology, Part I of this paper establishes a statistical data base for the shoulder complex sinus of the male population of ages 18-32. Estimates for the population mean and standard deviation as well as their confidence intervals are presented. The results are expressed in functional expansion form relative to a locally defined joint axis system as well as relative to the torso-fixed coordinate system in the form of globographic representation.
在过去二十年里，文献中出现了几种全身多节段数学模型。虽然这些模型能够处理非常复杂的负荷-运动情况，但其有效性在很大程度上取决于对人体主要关节的恰当生物力学描述和模拟。在这些关节中，最复杂且模拟最不成功的是肩部复合体，主要原因是缺乏合适的生物力学数据库以及肩部区域的解剖复杂性。1984年，资深作者及其同事提出了一种借助声波发射器和相关数据分析技术的新运动学数据采集方法。基于此数据采集方法，本文第一部分为年龄在18 - 32岁的男性人群的肩部复合体建立了一个统计数据库。给出了总体均值、标准差及其置信区间的估计值。结果以相对于局部定义的关节轴系统的函数展开形式以及相对于以球坐标表示形式的躯干固定坐标系的形式表示。
