Neurological injuries are the leading cause of serious, long-term disability. Physical rehabilitation therapy is indispensable for treating neurological disabilities. Therapies are more effective when they are intense, repetitive and targeted. Manual therapies are labor intensive and place high physical burden on therapists. Robotic devices in repetitive and physically involved rehabilitation eliminate the physical burden of movement therapy for the therapists, enable safe and versatile training with increased intensity, allow quantitative measurements of patient progress, increase the reliability, accuracy, and effectiveness of traditional physical rehabilitation therapies, realize innovative treatment protocols. We design and develop ergonomic powered exoskeletons, with AI add-ons, that can deliver personalized physical therapies to improve the quality of life of patients suffering from stroke.
