Perceived musculoskeletal discomfort caused by the repetition of a light work task was examined by rating the perceived musculoskeletal discomfort and measuring the muscle pressure pain threshold. Thirteen healthy female workers performed a repetitive light work task for 120 minutes. Based on the perceived musculoskeletal discomfort during the work task the subjects were assigned to one of two groups, i.e., those who reported most complaints and those who reported fewest complaints. The pressure pain thresholds of the trapezius muscles in the most-complaining group were significantly lower than those in the least-complaining group. The pressure pain threshold was logarithmically correlated both with the perceived musculoskeletal discomfort and with the EMG signal amplitudes.
通过对感知到的肌肉骨骼不适进行评分并测量肌肉压痛阈值，研究了由重复进行轻度工作任务引起的感知到的肌肉骨骼不适。13名健康女性工人进行了120分钟的重复性轻度工作任务。根据工作任务期间感知到的肌肉骨骼不适，将受试者分为两组，即抱怨最多的组和抱怨最少的组。抱怨最多组的斜方肌压痛阈值显著低于抱怨最少组。压痛阈值与感知到的肌肉骨骼不适和肌电图信号幅度均呈对数相关。
