Two Degree of Freedom Powered Orthosis

Rehabilitation engineering aims to improve the quality of life for individuals with varying disabilities. Paraplegia, for example, has seen significant attention from the rehabilitation field, offering several mobility devices, orthoses, and accessories to improve the client's independence. Other disabilities, such as Muscular Dystrophy (MD) may also benefit from the powered orthosis. MD is a genetic, degenerative disease, which destroys muscle tissue leading to decreased mobility and independence. A rehabilitation device which could increase the rang e of motion of muscle groups, would benefit clients with MD by improving their independence and overall quality of life. Such a product could have influence in the rehabilitation, therapeutic, and medical markets for clients with other afflictions such as stroke, terror, arthritis, and to assist in therapy for those recovering from surgery or injury.
