Abstract
A comprehensive study was conducted to investigate work-related musculoskeletal disorders (MSDs) among SkyTrain construction workers in Bangkok, Thailand. Focusing on a specific group of 42 workers employed across 14 job categories within a SkyTrain construction site. The primary objectives were to identify the types of musculoskeletal risks encountered and the contributing factors. A combined approach utilizing the Nordic Musculoskeletal Questionnaire (NMQ) and Rapid Entire Body Assessment (REBA) was employed on a sample of 42 workers across 14 job categories. Analysis of the NMQ data revealed a high prevalence of MSDs, with lower back pain being the most frequent complaint (55%). Wrist/hand and neck pain were also prevalent (45% and 50%, respectively). REBA scores identified tasks like shoveling, sweeping metal scraps, and grinding operations as having a higher risk of MSDs due to biomechanical factors. Based on these findings, the study recommends targeted interventions such as ergonomic improvements in the tools and equipment, training programs on safe work practices, and job rotation strategies to mitigate MSD risks and enhance worker health and safety in similar construction projects.
