A study of musculoskeletal discomfort of on-site welders

In modern enterprises, repetitive and monotonous work may cause work-related musculoskeletal injuries and diseases (WMSDs), such as cumulative traumatic injuries (CTDs). According to statistics, these injuries account for a high proportion of occupational injuries in various countries, causing significant economic losses. In order to address these problems, many companies have promoted human hazard prevention and control programs. The Nordic Musculoskeletal Questionnaire (NMQ) is a commonly used assessment tool to understand the musculoskeletal health of workers. This study evaluated the prevalence of musculoskeletal discomfort in welding workers through NMQ, analyzed the association with basic information, health behaviors and workload, and provided specific improvements to reduce the occupational hazards faced by workers in welding operations, help companies reduce human-related hazards, and achieve employee health and corporate sustainable development.
