本文提供了一个简短的回顾发表的文献上的主题的运动学和动力学的人的手臂和肩膀的机制，特别是在执行日常生活的任务。令人惊讶的是，只有少量的论文涵盖功能分析的手臂被发现，其中大多数只关注手肘和下臂的运动学。实验方法的差异和缺乏共识，以如何模拟关节轴的人的手臂，使结果难以比较。结果通常仅以臂段的角偏移的形式呈现，只有一份文件提供了关于角速度和加速度的数据。不同分析的结果表明，人类手臂是自适应的（由于其固有的机械冗余），显示出使用不同运动策略执行相同任务的能力。因此，上肢矫形器设计者的主要兴趣应该是由手的起点和终点定义的工作空间，以及在执行这些任务时保持所需的手方向。
This paper provides a brief review of the published literature on the subject of kinematics and kinetics of the human arm and shoulder mechanism, specifically when performing the tasks of everyday living. Surprisingly, only a small number of papers covering functional analysis of the arm were found, and the majority of these were concerned only with the kinematics of the elbow and lower arm. Differences in experimental method and a lack of consensus as to how to model the joint axes of the human arm make the results difficult to compare. Results are normally only presented in the form of angular excursion of the arm segments, with only one paper providing data on angular velocities and accelerations. The results of the different analyses suggest that the human arm is adaptive (due to its inherent mechanical redundancy), showing the ability to perform the same tasks using differing kinematic strategies. Therefore, the principal interest for the designer of upper limb orthoses should be the work-space defined by the start and end points of the hand, and the maintenance of the desired hand orientation when performing these tasks.
