Abstract
Musculoskeletal disorders are one of the common causes of occupational injuries and disability in developing countries. The World Health Organization defines musculoskeletal disorders as motor health problems. The purpose of this study was to investigate the effect of 8 weeks of selected corrective exercises on the improvement of work-related musculoskeletal disorders and work satisfaction in a food factory in Hamadan. In this quasi-experimental study, 32 subjects were assigned to the experimental (n = 16) and control (n = 16) groups. Before exercise interventions, the Nordic questionnaire was used to identify exposure to work-related musculoskeletal disorders, the VAS index was used to determine the severity of musculoskeletal pain, and the Minnesota questionnaire was used to obtain the work satisfaction. The frequency was obtained to investigate the prevalence of musculoskeletal disorders, and an independent t-test was used to determine the effect of selected exercises on pain and work satisfaction. Results: The study findings showed that musculoskeletal disorders in lumbar (58.25%), knee (47.57%), wrist (32.03%) and neck (31.03%) areas were the most prevalent. Also, the results of paired t-test indicated that after 8 weeks of selected corrective exercises, the level of pain in lumbar (P = 0.001), and knee (P = 0.001) again decreased significantly. In addition, work satisfaction increased significantly after this period (P = 0.0001). Musculoskeletal disorders in the lumbar, knee, wrist and neck areas, were the most observed disorder among the food factory workers, which should be corrected by ergonomic interventions. Besides, it seems that the selected corrective exercises have a positive effect on reducing work-related musculoskeletal pain disorders, and increasing the work satisfaction of workers.
