Background: Work-related musculoskeletal disorders (WMSDs) are a leading cause of disability and workers compensations.

Objectives: The research was done in Tehran Pars-electric factory to prevent inducing WMSDs. Rapid entire body assessment (REBA) was carried out to assess musculoskeletal loads on workers due to their postures, repetition, and force. Nordic musculoskeletal questionnaire (NMQ) was also used to obtain prevalence of entire body disorders.

Patients and Methods: All 673 workers aged 19-49 with mean age of 32.3 (SD = 11.9 years):355 males aged 25-49 with mean age of 38.9 (SD = 7.3 years); 318 females aged 19-33 with mean age of 25.6 (SD = 9.8 years) were examined. Total prevalences wrists, lower arms,upper arms, neck, trunk and legs disorders were gained 606 (90%), 532 (79%), 472 (70.1%),345 (51.3%), 243 (36.1%), and 404 (60%) respectively (P = 0.012).

Results: The number of tasks located in action levels of 2, 3 and 4 were 9, 11 and 12 tasks correspondingly. No tasks were placed in action level of 0 and 1.Thereby,further actions, ergonomic designing solutions, and multiple preventions are necessary.

ConclusionS: REBA tool is a useful and an applicable tool for assessing risk factors producing entire body disorders on workers performing various tasks in electric factory.
