Background: Musculoskeletal disorders in the upper limb are highly prevalent in different industries and are preventable by identifying the risk factors. Workload assessment is a key parameter in assessing the comfort, satisfaction, productivity, and safety. The aim of this study was to evaluate the workload and its relationship with upper limb disability in the assembly lines workers.Methods: This cross-sectional study was carried out on 120 assembly lines workers who were selected through random sampling method. For the evaluation of mental workload and disability of upper limbs, the Iranian version of NASA-Task Load Index (NASA-TLX) and Disability of the Arm, Shoulder, and Hand (DASH) questionnaire were used, respectively. Data analysis was carried out using SPSS software. P < 0.05 was considered significant.Findings: The most effective dimension on the mental workload was recognized to be the physical load. 45% of the subjects were placed in the “mild problem” group regarding the upper limb disability. Moreover, there was a significant relationship between the mental workload, efficiency, and frustration with disability of upper limb (P < 0.05).Conclusion: On the basis of the results, mental workload leads to different levels of upper limb disability. Furthermore, the reduction in mental workload will result in a decrease in physical workload and disability of upper limb.
