An ergonomics educational training program to prevent work-related musculoskeletal disorders to novice and experienced workers in the poultry processing industry: A quasi-experimental study

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.

Automated summary

This study evaluated the benefits of ergonomics educational training for novice and experienced workers in preventing work-related musculoskeletal disorders in a poultry processing industry. The training reduced musculoskeletal complaints in the neck, back, and wrists, with a decrease in pain intensity in the wrist region. Both novice and experienced workers showed a reduction in occupational biomechanical exposure, with novice workers experiencing a higher reduction in the cutting room. Overall, all workers benefited from the training in the short and medium term, emphasizing the importance of training content and approach in achieving success.
