Abstract: (1257 Views)
Introduction: In the last decade in Iran, the highest prevalence of musculoskeletal pain and discomfort in the neck and back and shoulder areas has been reported in office workers. This research was conducted with the aim of investigating the impact of ergonomic interventions in knowledge-based companies on musculoskeletal disorders, job stress and quality of work life.
Methodology: This research is a field study with a quasi-randomized trial with a control group. In this intervention study, the participants, including 311 office worker, received ergonomic interventions at both individual and managerial levels. The investigated variables were the prevalence of musculoskeletal disorders, job characteristics and the quality of work life of employees. After the implementation of the interventions, evaluations were repeated in the period of one, three and six months.
Results: The implementation of individual ergonomic training interventions significantly reduced disorders in the neck, right and left shoulders, right forearm and right wrist. Social support also shows a significant increase in all three intervention groups. The interventions have had a significant impact on the quality of working life. The changes in the average quality of working life for the second and third groups in the first month of growth were significant and then continued similar to the trend of the control group.
Conclusion: The implementation of individual ergonomic training interventions has been found to significantly reduce musculoskeletal disorders in the neck, shoulders and upper limbs. However, management training interventions did not affect the musculoskeletal disorders of employees. Furthermore, the concurrent implementation of individual ergonomics and management interventions has demonstrated a more pronounced effect on the reduction of disorders. The implementation of management educational interventions and combined interventions has led to an increase in the level of control experienced by participants, while both types of social support interventions have also increased. The implementation of a multi-component ergonomics intervention program has been demonstrated to enhance the impact of interventions on employee health and productivity
