The prevalence of musculoskeletal disorders among developing countries, according to the type and duration of work with computers, between 15 to 70% has been reported. The aim of this study was to evaluate musculoskeletal disorders in computer users and determination of correlation between the results of CMDQ, RULA and ROSA methods.
 Materials & methods: Participants were 71 office users that were selected using systematic random sampling. The method used in this correlation study was using CMDQ questionnaire and evaluation of those methods.
 Findings: According to the final results of the RULA 46% of participants were in risk level 3 and 4 (ergonomic intervention) and results of the ROSA 21% as low risk, 48% as medium risk and 31% were at high risk. Also there is a significant relationship between the risk level of two method results (p<0.05).
Discussion & Conclusion: Two evaluation methods have a high correlation to estimated risk levels of musculoskeletal disorders and they can be used as an alternative method to assessment of ergonomic risk of office environments.
