"This article focuses on the prevention of shoulder musculoskeletal disorders (MSDs) commonly associated with muscle fatigue and repetitive overuse in an occupational setting. The authors' purpose and motivation are the potential consideration of exoskeletons as PPE for shoulder injury prevention. An upper body exoskeleton is a wearable technology engineered to improve upper extremity musculoskeletal health in professionals and skilled trade workers who engage in repetitive arm motion or static elevation of the arms. Some upper body exoskeletons (such as the one shown in the photos on pp. 32 and 34) are lightweight and transfer the weight of the arms from the shoulders, neck and upper back to the body's core, evenly distributing energy to reduce stress."
