This quasi-experimental study was conducted in a poultry processing industry with the aim of assessing the benefits of ergonomics educational training for novice and experienced workers in preventing work-related musculoskeletal disorders. Sociodemographic and occupational questionnaires were used to evaluate age, marital status, education, time in job, musculoskeletal complaints and pain intensity, perceived effort, biomechanical exposure, and perception of ease or difficulty in adoption of ergonomics educational training. Musculoskeletal complaints in the neck, back, and wrists were reduced with training, but pain intensity was reduced only in the wrist region. A reduction in the occupational biomechanical exposure from the baseline to immediately post-training and 2 months after training both for novice and experienced workers was also observed. The novice workers group differed from the experienced workers by presenting a higher reduction of biomechanical exposure in the cutting room. All workers in this study benefited from the ergonomics educational training in the short and medium term. However, the success of training was highly dependent on the content and approach of the training.
本准实验研究在一家家禽加工行业进行,旨在评估针对新手和经验丰富工人的人体工程学教育培训在预防与工作相关的肌肉骨骼疾病方面的益处。采用社会人口学和职业调查问卷评估年龄、婚姻状况、教育程度、工作时间、肌肉骨骼投诉和疼痛强度、感知努力程度、生物力学暴露以及对人体工程学教育培训的接受难易程度的看法。培训后,颈部、背部和手腕的肌肉骨骼投诉减少,但仅在手腕区域疼痛强度降低。还观察到从基线到培训后即刻以及培训后 2 个月,新手和经验丰富工人的职业生物力学暴露均减少。新手工人组与经验丰富工人组的不同之处在于,在切割室中,生物力学暴露的减少幅度更高。本研究中的所有工人都在短期和中期从人体工程学教育培训中受益。然而,培训的成功高度取决于培训的内容和方法。
