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. The main objective of this study is to determine work- related musculoskeletal disorders and its related risk factors among Seymareh hydropower plant workers. Determination of disorders and its relevant factors are one the most leading basis for musculoskeletal disorder prevention programs in future. This cross sectional study was done in a Seymareh hydropower plant located in Illam. 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 assessment tool showed that there was a significant difference between the prevalence of the MSDs in the upper limbs and the age groups (P = 0.007). A significant difference exists between job groups and the risk of musculoskeletal disorders in the upper limbs (P = 0.01). No significant difference was found between marital status and the risk of musculoskeletal disorders in the upper limbs such as shoulder, arms, back, neck, wrist and hands (P = 0.770). MSDs symptoms increased with increasing workers age and work experience. Several workers experienced high level of exposure to ergonomic risk factors in their workplaces.
