基于远端上肢疾病的生理学、生物力学和流行病学的现有知识和理论，开发了一种半定量工作分析方法。该方法涉及测量或估计六个任务变量（运动强度、每个周期的运动持续时间、每分钟的运动强度、手腕姿势、运动速度和每天的任务持续时间）；根据暴露数据为每个变量分配顺序评级；然后为每个变量分配一个乘数值。应变指数是这六个乘数的乘积。初步测试表明，该方法可以准确识别与远端上肢疾病相关的工作和与远端上肢疾病无关的工作；然而，需要进行大规模研究来验证和更新拟议的方法。
Based on existing knowledge and theory of the physiology, biomechanics, and epidemiology of distal upper extremity disorders, a semiquantitative job analysis methodology was developed. The methodology involves the measurement or estimation of six task variables (intensity of exertion, duration of exertion per cycle, efforts per minute, wrist posture, speed of exertion, and duration of task per day); assignment of an ordinal rating for each variable according to exposure data; then assignment of a multiplier value for each variable. The Strain Index is the product of these six multipliers. Preliminary testing suggests that the methodology accurately identifies jobs associated with distal upper extremity disorders versus jobs that are not; however, large-scale studies are needed to validate and update the proposed methodology.
