Investigation of musculoskeletal disorders and its relevant factors using quick exposure check (QEC) method among seymareh hydropower plant workers

Musculoskeletal disorders (MSDs) are one of the most important problems in advanced and industrialized countries particularly in manufacturing companies. Determination of disorders and its relevant factors are one the most leading basis for musculoskeletal disorder prevention programs in the future.The aim of this study was to determine work-related musculoskeletal disorders and its related risk factors among hydropower plant workers. This cross sectional study was done in a hydropower plant located. All 215 workers in hydropower plant were examined. Workers were divided into 11 working groups. To perform the study, ergonomic assessment tools such as QEC (Quick Exposure Check) and validated Nordic Questionnaire were used. The results of Nordic Questionnaire and ergonomic assessment tool showed that low back and wrists symptoms were the most general musculoskeletal signs in workers. Significant differences were found between the prevalence of the MSDs in the upper limbs and the age groups and work experience of workers. Job groups were viewed as a risk factor for musculoskeletal disorders in the upper limbs. Marital status had no important effect on musculoskeletal disorders in the upper limbs such as shoulders, arms, back, neck, wrists and hands. Musculoskeletal disorders had a high prevalence among workers in this hydropower plant and control measures are required to minimize occupational exposure to work-related musculoskeletal disorders risk factors.
