Abstract
Introduction:
Musculoskeletal disorders (MSDs) represent one of the leading causes of
occupational injury and disability in the developed and industrially developing
countries. This study was conducted to investigate the prevalence of MSDs and
evaluate the risk of these disorders among
welders of a steel manufacturing industry.
Materials
and Methods: This descriptive-analytical study was achieved on all
243 welders employed in a steel manufacturing industry. Nordic Musculoskeletal
Questionnaire (NMQ) was used to study the prevalence of MSDs. Meanwhile, QEC
technique was employed to evaluate the risk of exposure to these disorders. For
data analysis, central statistical indices, T-test and Chi-square test were used.
Results: The results
suggested the highest prevalence of symptoms of musculoskeletal disorders in
low back, trunk and knees, respectively. QEC technique showed a high and very
high risk of exposure to MSDs in 64.6 %
of welders.
Conclusion: This study demonstrated that the prevalence of WMSDs in welders under
study was high. Based on the obtained results, the most significant ergonomic
problems in welders were found to be awkward postures, manual material handling
and back bending and twisting. Furthermore, the results suggested that QEC can
present reliable findings in evaluating the risk level of exposure to WMSDs.
