چکیده
conclusions the potential risk and prevalence of ulmsds among computer users of medical sciences university were less than those of technical-engineering university due to following ergonomic principles. rula found to be a proper method for the assessment of the ergonomic risk factors of the ulmsds in order to prevent such disorders. background along with widespread use of computers, work-related upper limb musculoskeletal disorders (ulmsds) have become the most prevalent ergonomic problems in computer users. thus, study of the ergonomic risk factors related to ulmsds in computer users has a special importance. objectives the present study was conducted to assess and compare ulmsds among computer users of zahedan universities of technical-engineering and medical sciences by nordic musculoskeletal questionnaire and rapid upper limb assessment (rula). patients and methods this cross-sectional study was conducted on 107 computer users (65 users from technical-engineering university; 42 users from medical university with a mean age of 33.84 ± 7.26 years). a combination of four methods of observation, interviews (to collect demographic data); nordic musculoskeletal questionnaire (nmq) (to determine the prevalence of pain signs and symptoms of upper limb musculoskeletal disorders); and rula (to assess the potential risk of ulmsds) were used. we used chi-square test for qualitative data analysis, independent-samples t-test for quantitative data analysis between two groups, and 1-way analysis of variance (anova) for multiple comparisons with 0.05 significant levels. results the highest and lowest of pain percentage in computer users belonged to back (77%) and shoulders (51.24%), respectively. the most percentage absenteeism belonged to lower back region (21.5%), and the most percentage over the past 12 months due to low back pain was 19.6%. pain signs and symptoms in the body parts of shoulder, back, and legs in computer users of technical-engineering university were more than those of medical sciences university. rula results showed that 30.8% of the computer users of technical-engineering university were located in corrective action level 3 (high risk level) and 42.9% of computer users of medical sciences at risk level 2 (moderate risk level). there was a significant relationship between age and rula final score (p < 0.05).
