This paper discusses the potential roles of work pace and work pressure as risk factors in the development of cumulative trauma disorders. Specifically, electromyographic (EMG) data were collected from the forearm flexor muscles of workers performing a highly repetitive task. This task had previously been identified as one that involved a high incidence of cumulative trauma disorders. Workers were asked to increase and decrease their work pace for short periods of time. The EMG data indicated that faster work paces were accompanied by higher forces. However, it was also noted that unsuccessful attempts to speedup or slowdown produced similar increases and decreases in EMG activity, indicating that speed of movement was not the only factor contributing to the changes in muscular activity. The results are discussed in relation to the stress and tension associated with work pressure caused by machine pacing, production standards, and incentive systems.
本文探讨了工作节奏和工作压力作为累积性创伤障碍发展的风险因素的潜在作用。具体而言，从从事高度重复性任务的工人的前臂屈肌收集了肌电图（EMG）数据。该任务先前已被确定为累积性创伤障碍发生率较高的任务。要求工人在短时间内加快和减慢工作节奏。EMG数据表明，更快的工作节奏伴随着更大的力量。然而，还注意到加速或减速的不成功尝试会导致EMG活动出现类似的增加和减少，这表明运动速度不是导致肌肉活动变化的唯一因素。结合由机器节奏、生产标准和激励系统引起的工作压力相关的压力和紧张来讨论结果。
