Work-related musculoskeletal disorders are known as chronic health hazards in the musculoskeletal system, resulting from minute injuries mainly in the joint regions and caused by repetitive manual work, inconvenient and awkward working postures, high labor intensity, excessive force, insufficient rest, cold working environments, or vibrations. The purpose of the present study is to judge whether low back pain and other musculoskeletal symptoms appear more significantly in sedentary work or standing work. The present study was conducted with 109 production workers of an electronic product manufacturing business that implement assembling processes along the flow of conveyor belts with typical sedentary work for eight working hours per day. In addition, it also included 116 production workers of a car component manufacturing business located in Gyeonggi-do that implement assembling processes in cell lines with typical standing work for eight working hours per day. More sedentary workers were shown to be pain complainants (21.1%) and management targets (54.1%) that felt pain in at least one region. Many complained of pain in the shoulder (15.6%) and the percentage of management targets among them was shown to be higher than standing workers were. As almost 70% of standing workers experiencing many physical burdens were shown to be healthy, except for those who were shown to be pain complainants, standing work is assumed to have healthy effects. As well, given that only 24.8% of sedentary workers were shown to be normal, sedentary workers should be managed through appropriate exercise therapy or health management.
