Wrist positions and movements were measured and a physical examination was conducted in 12 female operators in an industrial quality-control work. The handled products are of very low weight, thus, the work can be considered as non-forceful. The work was highly repetitive; 0.54Hz for the right wrist/hand and 0.41Hz for the left. The angular velocities were also high; for the right wrist/hand median value was 30 degrees /s and peak value 108 degrees /s, for the left wrist/hand 24 degrees /s and 88 degrees /s, respectively. The frequency of musculoskeletal disorders was high, especially for the right wrist/hand. Although the work was non-forceful and there were minor extreme positions in the wrists, the results are consistent with reported exposure-response relations in other high-risk jobs. Thus, the repetitiveness and the high velocities are the likely causes for the high prevalence of disorders in the wrists/hands among the operators.
对12名从事工业质量控制工作的女性操作员的手腕位置和动作进行了测量，并进行了体格检查。所处理的产品重量极轻，因此，这项工作可被视为非高强度工作。该工作重复性很高；右手腕/手的频率为0.54Hz，左手为0.41Hz。角速度也很高；右手腕/手的中位数为30度/秒，峰值为108度/秒，左手腕/手分别为24度/秒和88度/秒。肌肉骨骼疾病的发生率很高，尤其是右手腕/手。尽管这项工作并非高强度，且手腕的极端位置较少，但结果与其他高风险工作中报告的暴露-反应关系一致。因此，重复性和高速度可能是操作员手腕/手部疾病高发的原因。
