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:
Participant Tasks:
Shoulder musculoskeletal disorders, such as rotator cuff injuries, adhesive capsulitis, and osteoarthritis, severely impact daily activities due to pain, reduced mobility, and muscle weakness. These conditions limit tasks like lifting, reaching, and even simple activities such as dressing or combing hair, significantly affecting patients' quality of life. While traditional physiotherapy can help, barriers such as limited access and poor adherence to home exercises hinder its effectiveness. This has led to the exploration of new rehabilitation methods, particularly passive exoskeletons.
Passive exoskeletons, which use mechanical components like springs to assist movement without external power, have shown potential in reducing muscle strain and supporting tasks requiring arm elevation or lifting. These devices are lightweight, cost-effective, and easy to use, but research on their application for patients with musculoskeletal disorders is limited.
This study aims to assess the impact of passive exoskeletons on joint functionality, pain reduction, and performance of activities of daily living (ADLs) in patients with shoulder disorders. It will also evaluate the usability and comfort of the devices using validated questionnaires. Participants will be enrolled from the FPUCBM Unit of Traumatology and Sports Medicine and undergo experimental sessions involving movement tasks with and without the exoskeleton. The study will measure biomechanical effects, pain levels, and user satisfaction, with the ultimate goal of integrating passive exoskeletons into clinical rehabilitation protocols to improve patient outcomes.

| Patients with shoulder musculoskeletal disorders | Experimental | The study will involve 15 adults with shoulder musculoskeletal disorders. Eligible participants must be over 18 years old and diagnosed with conditions such as rotator cuff tears, adhesive capsulitis, or osteoarthritis. Individuals with neurological conditions, infections, inflammatory diseases, prior major shoulder surgeries, or those who are pregnant will be excluded. After obtaining informed consent, baseline demographic and anthropometric data will be collected. Patients will be assessed during a series of experimental sessions at the Lab of Motion Analysis, where they will perform relevant activities of daily living (ADLs) with and without the assistance of a passive exoskeleton. These sessions will include evaluations of joint functionality, pain, and muscle activity using wearable sensors, EMG measurements, and kinematic analysis. |

| Passive Exoskeleton. | Device | The passive exoskeleton is used to assist patients with shoulder musculoskeletal disorders during the performance of activities of daily living (ADLs), such as overhead reaching and lifting. The device helps reduce biomechanical load and muscle strain, providing support for the shoulder joint. |
| Measure | Description | Time Frame |
|---|---|---|
| Measurement of Joint Range of Motion (ROM) | Joint Range of Motion (ROM) will be evaluated using stereophotogrammetric systems, and wearable sensors during the execution of movements with and without the exoskeleton | a single session up to one year from the subject's enrollment |
| Pain Assessment using the Visual Analogue Scale (VAS) before and after exoskeleton use | Pain levels will be measured using the Visual Analogue Scale (VAS) before and after exoskeleton use. The VAS provides a quantitative measure of pain intensity, with scores ranging from 0 (no pain) to 10 (worst pain imaginable). | a single session up to one year from the subject's enrollment, before and after exoskeleton use |
| Evaluation of the American Shoulder and Elbow Surgeons Score (ASES) | The ASES score will be used to evaluate shoulder function and pain. This clinical scale assesses both pain and the ability to perform daily activities, with higher scores indicating better function. The total score ranges from 0 to 100, with 0 representing the worst shoulder function and 100 indicating the best possible outcome. | a single session up to one year from the subject's enrollment |
| Evaluation of the Disabilities of the Arm, Shoulder, and Hand Score (DASH) | The DASH questionnaire will assess disability and symptoms in people with upper limb musculoskeletal disorders. Higher scores indicate greater disability. The total score ranges from 0 to 100, with 0 representing no disability and 100 indicating the most severe disability. | a single session up to one year from the subject's enrollment |
| Evaluation of the Short Form Health Survey 36 (SF-36) | The SF-36 will evaluate overall health-related quality of life, covering physical functioning, bodily pain, and general health perceptions. Higher scores indicate better health status. The total score ranges from 0 to 100, with 0 representing the poorest health status and 100 indicating the best possible health status. |
| Measure | Description | Time Frame |
|---|---|---|
| Evaluation of the Usability Level of the passive exoskeleton using the System Usability Scale (SUS) | The usability of the passive exoskeleton will be assessed using the System Usability Scale (SUS), a standardized questionnaire consisting of ten statements rated on a five-point Likert scale from "Strongly Disagree" to "Strongly Agree." Higher scores indicate better usability. | a single session up to one year from the subject's enrollment |

| Shoulder Rehabilitation with Passive Exoskeleton. | Procedure | The rehabilitation protocol involves the use of a passive exoskeleton during physical tasks to improve shoulder function and reduce pain. Patients perform specific exercises while wearing the exoskeleton, which is tailored to their individual needs. |
