“…Foundry process activities have a high potential to cause WMSDs; because the majority of the tasks are performed manually. Research on the physical load of the workers in the foundry industry demonstrated that the activities of breaking and debarring impose a high physiological demand, once the difference of the heart rate between resting and performing those activities exceeds the acceptable physiological limits of the working load [ 20 ].…”

“…The results of another study carried out in Chinese foundries illustrated that the most affected areas after 12 months of work are the back (29.2%), shoulders (10.5%), and hands and wrists (6.2%) [ 22 ]. Another study about the physical load of workers in Brazilian foundries showed 75.2% of workers reported some WMSDs symptoms in the past 12 months, 53.3% reported symptoms the last seven days, and 38.5% reported already taking time off due to this problem [ 20 ].…”

Background Musculoskeletal disorders (MSDs) are known as one of the main problems affecting the health of industrial workers and can lead to lost working days, functional disability of workers and wasting the financial resources of an organization. Therefore, the present study aimed to evaluating the effect of ergonomic interventions on reducing MSDs and improving working posture in the in a foundry industry workers. Methods A field multicomponent cross-interventional study was conducted on workers working in a foundry industry. In this study, 117 male workers were divided into 4 groups, including a control group, a group with specialized ergonomics training, a group with workstation intervention, and a group simultaneously undergoing training and workstation intervention. All 4 groups were evaluated during a period of baseline, 6 and 12-months follow- up. The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and direct observations of working postures by using the Quick Exposure Check (QEC) method were used. Results The results showed that the implemented interventions in the shoulder/arm, back and stress level were effective and the difference in the final score was significant among different groups (P-value > 0.05). In addition, the interventions led to a significant decrease in the QEC scores and musculoskeletal symptom scores in the neck, shoulder, lower back, knee, and lower leg regions among different groups (P-value > 0.05). Conclusion The results showed that workstation modification and training and workstation intervention simultaneously had a greater effect on MSDs and improving working posture compared to training alone.
