A series of subjective and objective measures were chosen to determine impairment of upper extremity function in 157 workers performing repetitive tasks. Workers were asked to respond to questions regarding their perception of the presence or absence of numbness, pain, weakness, or swelling in their upper extremities. Objective tests consisted of the measurement of grip strength, pinch strength, Semmes-Weinstein monofilament sensory responses, vibrometer responses, neurometer measurement, and the presence or absence of Tinel's or Phalen's signs. These measures were considered collectively to estimate the overall levels of impairment of each individual. Overall findings show that 55 percent of workers examined had impairment scores of 2 or more and 75 percent had scores of 1 or more. Significant differences were found in impairment ratings between job types. Those jobs requiring the highest repetition with the least rest per cycle had the highest impairment ratings. Workers that rotated jobs had impairment scores significantly less (p less than 0.005) than the average of workers performing single-task jobs. We conclude that cumulative trauma disorders are more prevalent than originally believed and that the disorder is best examined from an overall functional impairment perspective.
选择了一系列主观和客观指标来确定157名从事重复性任务的工人上肢功能的损伤情况。要求工人回答有关他们对上肢是否存在麻木、疼痛、无力或肿胀的感知的问题。客观测试包括握力、捏力、Semmes-Weinstein单丝感觉反应、振动计反应、神经仪测量以及是否存在Tinel征或Phalen征。综合考虑这些指标来估计每个个体的总体损伤水平。总体研究结果表明，接受检查的工人中有55%的损伤评分达到2分或更高，75%的评分达到1分或更高。不同工作类型之间的损伤评级存在显著差异。那些每个周期重复次数最多且休息时间最少的工作，其损伤评级最高。轮岗的工人的损伤评分显著低于（p小于0.005）从事单一任务工作的工人的平均水平。我们得出结论，累积性创伤障碍比最初认为的更为普遍，并且最好从总体功能损伤的角度来检查这种障碍。
