Passive Exoskeletons for Assisting Patients With Shoulder Musculoskeletal Disorders

Goal: The clinical investigation aims to evaluate the usability of passive exoskeletons, their impact on daily living activities, and the perceived experience of patients with shoulder musculoskeletal disorders. This will be assessed through specific validated questionnaires. Participant Population: The study will enroll 15 participants diagnosed with shoulder musculoskeletal disorders, including rotator cuff tears, adhesive capsulitis, and glenohumeral osteoarthritis. Participants must be employed in physically demanding jobs that require frequent upper limb activity. Main Questions: * How does the integration of passive exoskeletons in daily activities influence usability and functional performance in patients with shoulder musculoskeletal disorders? * To what extent does the use of passive exoskeletons improve the perceived physical effort and quality of life in these patients? * How do patients perceive the comfort and effectiveness of passive exoskeletons during the execution of daily living tasks? Participant Tasks: * Comprehensive shoulder physical examination. Instruction on the proper use of the Paexo passive exoskeleton and customization of its settings. * Execution of workplace-relevant tasks (e.g., lifting, overhead reaching) with and without the exoskeleton. * Evaluation of usability, comfort, and perceived workload using validated scales such as the System Usability Scale (SUS), NASA Task Load Index (NASA-TLX), and Technology Acceptance Model (TAM).
