This paper is an investigation of the relationship between resultant joint torques and in vivo muscular activity. This relationship is currently inaccessible by direct experimental measurements due to the limited usefulness of electromyographic (EMG) data to indicate muscle force reliably and to proscriptions and experimental difficulties related to in vivo measurements on human subjects. The standard indirect method for inferring information about this relationship, using model studies in conjunction with temporal EMG data, is discussed. Key assumptions incorporated in these model studies, which lead to values for the joint force and torque resultants, are reviewed. The general distribution problem is formulated, and key assumptions associated with generating the simplified distribution problem that governs muscle activity are described. Two basically different methods for solving the simplified distribution problem and therefore determining the approximate relationship between resultant joint torques and muscular activity, including methods that attempt to account for the effect of antagonistic muscular activity, are discussed.
本文旨在研究合成关节扭矩与体内肌肉活动之间的关系。由于肌电图（EMG）数据在可靠指示肌肉力量方面的作用有限，以及与人体受试者体内测量相关的规定和实验困难，目前无法通过直接实验测量来获取这种关系。本文讨论了使用模型研究结合时间EMG数据来推断这种关系信息的标准间接方法。回顾了这些模型研究中包含的关键假设，这些假设可得出关节力和合成扭矩的值。阐述了一般分布问题，并描述了与生成控制肌肉活动的简化分布问题相关的关键假设。讨论了两种基本不同的解决简化分布问题并因此确定合成关节扭矩与肌肉活动之间近似关系的方法，包括试图考虑拮抗肌活动影响的方法。
