Abstract: 

Background and Objective: Currently, musculoskeletal disorders (MSD) are one of the most common causes of occupational injuries and disability in industrialized and developing countries. MSDs impose heavy economic burdens that not only affect individuals, but also organizations and community. It is worth mentioning that the rapid entire body assessment (REBA) method is designed to assess occupations with dynamic or static postures and is used for assessing the risk of MSDs.
Materials and Methods: This interventional study was conducted in the sliding gate and plastering stations of a steel company. To assess workers’ postures, the REBA and ManTRA techniques were applied before and after the intervention, and for ergonomic intervention, corrective engineering measures were implemented.
Results: The findings showed a 63% and 64% reduction in the risk level at the plastering and sliding gate stations using the REBA technique and a 47% and 56% reduction in the ManTRA cumulative risk score at the plastering and sliding gate stations. In addition, data analysis showed a significant difference in the ultimate risk level scores in the REBA and ManTRA techniques before and after the intervention (P=0.001).
Conclusion: The simultaneous use of the ManTRA and REBA techniques is beneficial for occupations involving manual activities in addition to the entire body involvement; activity duration is also important in these techniques. It should be noted that the limitations of each method will be minimized using the other technique.
