شغلی و ناتوانی در کشورهای صنعتی و کشورهای در حال توسعه است. این مطالعه با هدف ارزیابی
شیوع اختلالات اسکلتی- عضلانی و ارزیابی سطح ریسک ابتلا به این اختلالات در جوشکاران
یک صنعت تولید سازههای فلزی انجام شده است</span><span dir="ltr"></span><span dir="ltr"></span><span style="font-size: 10pt line-height: 107% font-family: "Tahoma","sans-serif"" dir="ltr"><span dir="ltr"></span><span dir="ltr"></span>.</span><span lang="AR-SA" style="font-size: 10pt line-height: 107% font-family: "Tahoma","sans-serif""></span></p>

Musculoskeletal disorders (MSDs) represent one of the leading causes of

and Methods:</span><span style="font-family: "Times New Roman","serif""> 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 </span><span lang="EN" style="font-family: "Times New Roman","serif"">Chi-square test</span><span style="font-family: "Times New Roman","serif""> were used.</span></span></p><span style="background-color: rgb(255, 255, 255)"> </span><p style="margin-bottom: 0.0001pt text-align: justify line-height: normal background-image: none background-repeat: repeat background-attachment: scroll background-position: 0% 0% background-clip: border-box background-origin: padding-box background-size: auto auto" class="MsoNormal"><span style="background-color: rgb(255, 255, 255)"><span style="font-family: "Times New Roman","serif"">Results:</span><span style="font-family: "Times New Roman","serif""> The results

low back, trunk and knees, respectively. QEC technique showed a high and very
high risk of exposure to MSDs in<span> </span>64.6 %
of welders.</span></span></p><span style="background-color: rgb(255, 255, 255)">

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. </span></span><!--stripped-->
