Impact of an exercise and health education program for health promotion in textile workers: a pre-post intervention...

Work-related musculoskeletal disorders are highly prevalent among manufacturing workers and represent a major cause of pain, functional limitation, reduced work ability and productivity loss, particularly in textile settings characterized by repetitive upper-limb tasks and sustained postures. Despite recommendations supporting exercise and education as first-line strategies, scalable workplace-embedded programs remain insufficiently implemented. This study aims to evaluate changes associated with an eight-week multimodal intervention integrating health education and app-supported exercise in textile workers. A quasi-experimental single-arm pre-post study will be conducted in a textile manufacturing company in Zaragoza, Spain, including workers aged 18-65 years. The intervention will consist of weekly face-to-face educational workshops and a twice-weekly digitally supported exercise program. Outcomes will be assessed at baseline, post-intervention and one-month follow-up. The primary outcome will be change in musculoskeletal pain intensity, and secondary outcomes will include musculoskeletal symptoms, physical function, physical activity, work ability, sleep quality, psychological distress, health-related quality of life and work productivity. Data will be analyzed using paired statistical tests according to distribution, with a significance level of 0.05. The study has received ethical approval from the Universidad San Jorge Ethics Committee and the Research Ethics Committee of Aragón, and findings will be disseminated through peer-reviewed publications and scientific conferences.
