对抗工作相关的上肢肌肉骨骼疾病（UEMSD）的一种方法是通过手动任务的定量生物力学表征（包括关节姿势、关节动力学和用力）来提高对MSD风险因素的理解。本文介绍了一种方法，用于定量评估专业打字在工作场所的设置，以及评估的结果。基于非任务特异性生物力学术语，比较了不同类型的打字任务之间以及打字和手密集型工业任务之间的结果。手动任务的定量生物力学表征将导致确定关节运动学和用力的适当范围，这反过来又有助于手动任务的正确设计。此外，该方法可用于评估正确（健康）技术的熟练任务的手动性能，或用于评估康复过程中的进展（受损工人的运动开始类似于健康工人的运动？）。
One approach to combating work- related upper extremity musculoskeletal disorders (UEMSDs) is to improve understanding of MSD risk factors through quantitative biomechanical characterization of manual tasks, including joint postures, joint dynamics, and force exertion. This paper describes a methodology employed to quantitatively assess professional typing in a workplace setting, and the results of that assessment. Results are compared between different kinds of typing tasks, and between typing and hand- intensive industrial tasks, based on nontask- specific biomechanical terms. Quantitative, biomechanical characterizations of manual tasks will lead to identification of appropriate ranges for joint kinematics and force exertion, which will, in turn, facilitate proper design of manual tasks. Additionally, the methodology could be used to assess manual performance of skilled tasks for proper (healthy) technique, or be used to evaluate progress through a course of rehabilitation (when do an impaired worker's motions begin to resemble motions of healthy workers?).
