A Field Evaluation of Arm-Support Exoskeletons for Overhead Work Applications in Automotive Assembly

Abstract

OCCUPATIONAL APPLICATIONS The results of this field trial suggest that when made available for optional usage during overhead automotive assembly, arm-support exoskeletons can lead to a substantial decrease in self-reported musculoskeletal discomfort in the neck and shoulders. Participants (assembly operators) chose to use the device for 86% of their shift and indicated they would continue to use it daily if provided the opportunity. The results of this investigation suggest that when used alongside a traditional proactive ergonomics program, arm-support exoskeletons may reduce some risk factors associated with the development of shoulder injuries. The approach presented may be useful for practitioners that are starting to explore arm-support exoskeletons in their workplace. Several areas of improvement were highlighted for future design consideration, including further reducing weight and improving thermal comfort.
