Abstract

OBJECTIVE: Examine arm-support exoskeleton (ASE) user experience over time, identify factors contributing to ASE intention-to-use, and explore whether ASE use may influence the number of medical visits. METHODS: An 18-month, longitudinal study with ASE (nā€Š=ā€Š65) and control groups (nā€Š=ā€Š133) completed at nine automotive manufacturing facilities. RESULTS: Responses to six usability questions were rather consistent over time. ASE use perceived effective in reducing physical demands on the shoulders, neck, and back. Perceived job performance, and overall fit and comfort, appeared to be key determinants for ASE intention-to-use. Based on medical visits among both groups, ASE use may decrease the likelihood of such visits. CONCLUSIONS: These field results support the potential of ASEs as a beneficial ergonomic intervention, but also highlight needs for further research on ASE designs, factors driving intention-to-use, and health outcomes.
