The aim of this review was to provide an overview of assistive exoskeletons that have specifically been developed for industrial purposes and to assess the potential effect of these exoskeletons on reduction of physical loading on the body. The search resulted in 40 papers describing 26 different industrial exoskeletons, of which 19 were active (actuated) and 7 passive (non-actuated). For 13 exoskeletons, the effect on physical loading have been evaluated, mainly in terms of muscle activity. All passive exoskeletons retrieved were aimed to support the low back. 10 to 40% reductions in back muscle activity during dynamic lifting and static holding have been reported. Both lower body, trunk and upper body regions could benefit from active exoskeletons. Muscle activity reductions up to 80% have been reported as an effect of active exoskeletons. Exoskeletons have the potential to considerably reduce the underlying factors associated with work-related musculoskeletal injury.
Practitioner SummaryWorldwide, a significant interest in industrial exoskeletons does exist, but a lack of specific safety standards and several technical issues hinder mainstay practical use of exoskeletons in industry. Specific issues include discomfort (for passive and active exoskeletons), weight of device, alignment with human anatomy and kinematics, and detection of human intention to enable smooth movement (for active exoskeletons).2
Five case studies on production line design were described to study the effect of an early design support tool. Based on these case studies, the simple, interactive, real-time, medium-fidelity, mixed-reality methodology was not only found to be a good early design stage evaluative tool for ergonomics and workflow, but a teaching tool as well. Despite some drawbacks, such as limited accuracy, mixed-reality simulation appears to be a good compromise between cost and fidelity, especially for small to mediumsized manufacturing enterprises, and gives important information on the layout focused on high efficiency and healthy postures.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
