Evaluation of work-analysis tools and an intervention strategy for the prevention of back disorders in the Metal and Electrical Products Fabrication sector

Abstract

The participatory ergonomic process has often provided interesting results for the prevention of musculoskeletal disorders (MSDs) when it has been introduced in companies where the context was favourable to this approach. To learn more about this type of intervention, this study compared the implementation of a participatory approach in a plant with a favourable context and in a company with an unfavourable context. The researchers also wanted to validate in the field a job analysis process designed for varied long-cycle tasks, which are more complex to analyze than repetitive tasks. Throughout the intervention, the difficulties that the ergo groups’ participants had in learning the job analysis process were documented. Optimal results were obtained in a favourable context: major changes were generated and the participants mastered the job analysis process. In an unfavourable context, the results were more modest: the intervention allowed the implementation of several solutions more modest than in the first company. However, problems occurred during the intervention and the ergo group participants had major difficulties learning the job analysis process, even though a significant change was observed near the end. The authors conclude that this analytical process adapted to varied tasks is not generalizable. They believe that further research is necessary in order to develop tools and intervention approaches that are better adapted to companies with a more difficult context.
