What this Trial Is About
Researchers are evaluating how a muscle-mimicking, fabric-type shoulder orthosis affects upper limb functional movements in patients with neuromuscular disorders. The study aims to understand if wearing this shoulder orthosis changes upper limb function, range of motion, and muscle activity compared to not wearing it. This research is important for patients with conditions such as muscular dystrophies, motor neuron diseases, peripheral neuropathies, and spinal cord injuries who experience upper limb muscle weakness. Participants will use the shoulder orthosis device, which mimics muscle function, and receive education on how to wear and operate it. The study compares various measurements before and after wearing the orthosis. These include upper limb performance, shoulder muscle strength, active range of motion, functional workspace, goal attainment, surface electromyography, heart rate, blood pressure, pain levels, and hand dexterity tests. During the study, participants will undergo multiple assessments to evaluate upper limb movement and physiological responses. Researchers will monitor muscle activity and function with and without the orthosis in place. Participants will be observed while performing standard tasks lasting approximately 3 to 4 hours. The study includes safety checks for any musculoskeletal or skin issues and fatigue evaluations. The total participation time and follow-up details are based on these evaluations to determine the orthosis's impact.
