Musculoskeletal disorders is very common in drivers of public vehicles. Therefore, the purpose of this study was to measure the correlation between muscle fatigue assessment (MFA) and Cornell musculoskeletal discomfort questionnaire (CMDQ) in taxi drivers in Shahroud in 2017. This descriptive study was performed on 140 taxi drivers in Shahroud in 2017. Data were collected using demographic questionnaire, CMDQ and MFA chart. Statistical analysis was performed by descriptive statistics (frequency, percentage, mean) and inferential statistics (Eta coefficient). The MFA results showed that 82% of lumbar muscle fatigue level was very high. The CMDQ results also showed that most musculoskeletal disorders was in the lower back and the least musculoskeletal disorders was in the forearm. Correlation between MFA and CMDQ showed that the highest correlation was in the back region with Eta=0.574 and the lowest correlation was in the neck region with Eta=0.294. The high correlation between MFA and CMDQ showed that MFA can be used instead of CMDQ. CMDQ is a self-report method and there is the possibility of non-cooperation or false report..
