Work-related musculoskeletal disorders, particularly low back pain, are common among logistics workers due to frequent lifting, repetitive movements, and awkward postures. Although laboratory studies suggest that occupational exoskeletons can reduce biomechanical load, evidence from long-term, real-world workplace implementations remains limited.\n\nThe RELAX project is an 18-month controlled in-field intervention study conducted in two departments of a Danish warehouse. Approximately 90 full-time warehouse workers will participate. Workers in the intervention department will use a passive back-support exoskeleton during manual order-picking tasks, while workers in the control department will continue their work as usual.\n\nThe primary outcomes include sickness absence, employee turnover, perceived work intensity, and musculoskeletal discomfort. Secondary outcomes include productivity, user acceptance of the exoskeleton, and cost-effectiveness of the intervention. Outcomes will be assessed through company records, repeated questionnaires, and focus-group interviews over the 18-month period.\n\nBy combining longitudinal quantitative outcomes with qualitative process evaluation, the study aims to determine whether long-term use of a passive back-support exoskeleton can improve worker well-being and reduce work-related musculoskeletal burden without negatively affecting productivity. The results may inform workplace policies and future implementation of occupational exoskeletons in physically demanding industries.",[88],"Work-Related Musculoskeletal Disorders",[90,91,92,93,94,95],"Occupational Exoskeletons","Musculoskeletal Disorders","Manual Materials Handling","Ergonomics","Assistive Technology","Warehouse","NOT_YET_RECRUITING","2026-05-01",{"date":99,"type":100},"2026-05-07","ACTUAL",{"date":102,"type":82},"2026-08-01",{"date":104,"type":82},"2029-10-31",{"name":5,"class":6},1]
