OBJECTIVE: The purpose of this research was to conduct assessment of ergonomic conditions of systems analysts in order to understand the factors causing physical and cognitive overload, its implications for workers and propose improvements to reduce these physical and cognitive overload. METHODOLOGY: The SHTM (human-machine-task) method was used for ergonomic evaluation, the Corlett diagram for evaluation of bodily discomfort, questionnaire evaluation of the furniture and the NASA-TLX to assess mental workload. RESULTS: It was found a prevalence of pain in the lumbar spine of 71% and 64% of respondents in the cervical spine. After evaluation of mental workload, it was observed that the mental demand was most required among systems analysts and the average loading rate was of 13.23. CONCLUSION: It can be concluded that the high prevalence of musculoskeletal pain may be caused by the presence of inappropriate furniture, adoption of incorrect postures and high mental demand of the developed activities performed by systems analysts.
