Additionally, the prevalence rate of reported musculoskeletal disorders in experimental group was significantly reduced following intervention (p≤0.05). After corrective measures, level of risk was decreased and working postures were improved. A significant relationship was observed between risk levels and neck and shoulder pain in the experimental group (p≤0.05). Following the intervention, workstations scores were increased significantly.
