Abstract: (125 Views)
Background and Objective: Musculoskeletal disorders (MSDs) are among the main occupational health challenges in industries with demanding working conditions, such as petrochemical plants. This study aimed to investigate the effect of a combined ergonomic and exercise intervention on pain reduction and motor performance improvement in employees of Ilam Petrochemical Company.
Methods: This quasi-experimental study utilized a pretest-posttest design with 40 male workers. Participants were randomly assigned to either an intervention group (receiving ergonomic training combined with exercise) or a control group. Data were collected using the Nordic Musculoskeletal Questionnaire (NMQ) and Motor Performance Questionnaire (MPQ), and analyzed using independent t-tests and repeated measures ANOVA.
Results: The combined intervention significantly reduced pain in the lower back (55%), shoulders (56%), and knees (57%), while improving the total motor performance score (43%) (p < 0.001). Cohen’s d effect sizes ranged from 1.8 to 2.5, indicating high effectiveness.
Conclusion: The integration of ergonomic and exercise interventions led to a significant reduction in musculoskeletal pain and improvement in motor performance among petrochemical workers. These findings demonstrate the positive impact of the intervention on workers' motor performance indicators.
