Conventional, clinically available techniques used in the measurement and analysis of human movement are overviewed in the first part of the article. I examine the data produced by these techniques in terms of information content and potential usefulness in assessing human movement. Consideration is given to the observation process and to specific techniques for determining temporal and spatial, kinematic, and kinetic variables. The techniques examined document the end result of the movement process, which limits the information content to a descriptive level. Of these descriptive variables, the temporal and spatial variables have the advantage of being much easier to obtain and interpret. In the last part of the paper, I review more complex methods of analysis. These methods enable the determination of mechanical energy levels and joint moments, which exposes the underlying biomechanics of the movement. Such information can be related to the causes of the movement disorder and can help to diagnose the abnormal movement pattern.
本文第一部分概述了用于人体运动测量和分析的传统临床可用技术。我从信息内容和评估人体运动的潜在有用性方面研究了这些技术产生的数据。考虑了观察过程以及确定时间和空间、运动学和动力学变量的具体技术。所研究的技术记录了运动过程的最终结果，这将信息内容限制在描述性层面。在这些描述性变量中，时间和空间变量具有更容易获取和解释的优势。在论文的最后一部分，我回顾了更复杂的分析方法。这些方法能够确定机械能水平和关节力矩，从而揭示运动的潜在生物力学原理。此类信息可与运动障碍的原因相关联，并有助于诊断异常运动模式。
