In this study, various physical, physiological, and psychological parameters of 12 subjects are analyzed and compared while performing overhead tasks with and without the Paexo Shoulder exoskeleton. The assessment criteria used to evaluate the Paexo Shoulder measure both the objective and subjective effects on the users.
The study concludes, as one of its findings, that using the Paexo Shoulder exoskeleton significantly reduces anterior deltoid muscle activation by 55%, oxygen consumption by 33%, and heart rate by 19% (objective evaluation criteria). This indicates that the Paexo Shoulder efficiently reduces physical stress and fatigue.
Subjective evaluation criteria included task performance and the potential change in the user’s range of motion while wearing the exoskeleton. The study shows that wearing the Paexo Shoulder feels natural and unrestricted and has neither positive nor negative effects on mere work performance. Overall, the researchers rate the Paexo Shoulder as a promising solution to reduce musculoskeletal disorders in the shoulder.
