摘要：The musculoskeletal disorders cover a large percent of occupational
diseases; therefore, in order to protect workers from such disorders, there is a
need to evaluate workers positions at work in different industries. In a major
furniture manufacture located in Tehran, 500 workers were examined. These
workers were divided into fourteen working groups, including production lines of
water-heater, air condition, electromotor production line, dunnage making hall,
plastic hall, smithery, restaurant, store, engineers and supervisors,
facilities, transportation, assembly of absorptive refrigerator and drivers. The
results from Nordic Questionnaire and performing the evaluation method showed
that, there was a significant relevance between outbreak of back pain and
workgroups (P=0.005) and between the outbreak of pain in neck and workgroup as
well. A significant relevance of P=0.005 indicating that, the working in the
above mentioned work-place causes pain in both back and neck. Between other
parts of the body and workgroup no significant relevance observed. Among
workgroups, there was a significant relevance between the water-heater
production line (P<0.005) and pain in the back, and there was also a
significant relevance among the work in air–conditioning production line and the
plastic injection (P=0.002), causing pain in the neck. The results from Quick
Exposure Check (QEC) in one hundred working posture have shown that 10% of them
fall into first and second level and 90% of them were categorized in third and
forth levels.
