Safety and Feasibility of Exoskeletal Network Device for Forearm Supination Assistance in Stroke Survivors Assisting Stroke Survivors With Engineering Technology (ASSET): ExoNET for Forearm Supination

What this Trial Is About

Researchers are evaluating the safety, feasibility, and effectiveness of a passive robotic device called the forearm ExoNET, designed to assist forearm supination in adults who have survived a stroke. This device uses a network of springs to provide gentle support and has the potential to improve motor learning and rehabilitation for individuals with neurological impairments. The study focuses on adults aged 40 to 70 who have moderate to severe upper arm impairment due to a single stroke occurring at least eight months prior. The study involves testing three configurations of the ExoNET device: one tuned to assist forearm supination, one set as a sham with slack springs providing no real force, and one tuned to resist forearm supination. Participants will wear the device during daily upper extremity tasks that require forearm supination. The device's effects will be monitored using wearable sensors that measure muscle activity and arm movements. Participants will be assessed at baseline and during follow-up sessions using the Action Research Arm Test (ARAT) to measure arm function. Researchers will also monitor muscle activity and range of motion with electromyography and motion sensors. Safety, feasibility, and patient tolerance of the device will be observed throughout the study, which involves several testing visits over a few weeks.
