Improvement Plan for the Prevention of Musculoskeletal Disorders to Minimize the Rate of Medical Leave in the Overhaul Operations Workshop

Due to the medical leaves reported in the overhaul workshop in Lima, this study investigated the causes of occupational risks and the incidence of medical interruptions in the overhaul workshop located in Lima. Over a 12-month period, the study analyzed productivity before and after the implementation of an ergonomic risk control program in the areas of body assembly, body repair, electrical workshop, and differential axles, with the objective of assessing occupational risks and providing training to the workers. The study followed a pre-experimental design with a phased methodological approach. The sample consisted of 10 workers, selected through non-probability sampling. Data collection was conducted using the Nordic Musculoskeletal Questionnaire and the OWAS method to evaluate working postures. The percentage of absenteeism decreased after the implementation of the improvement plan, reaching a reduction of 0,11%. Based on the results obtained, conclusions can be drawn to support the development of ergonomic studies aimed at improving workplace health and safety, increasing company productivity, and reducing medical leaves among workers.
