DARPA’s LUKE Arm – Prosthetic
On Friday, June 30th, at a ceremony at the Manhattan campus of the Department of Veterans Affairs’ New York Harbor Health Care System, two veterans living with arm amputations became the first recipients of a new generation of prosthetic limb that promises them unprecedented, near-natural arm and hand motion. The modular, battery-powered arms, designed and developed by DEKA Research and Development Corporation for DARPA, represent the most significant advance in upper extremity prosthetics in more than a century.
The prosthetic “LUKE” arm system—which stands for “Life Under Kinetic Evolution” but is also a passing reference to Luke Skywalker of Star Wars fame—enables dexterous arm and hand movement through a simple, intuitive control system. The system allows users to control multiple joints simultaneously and provides a variety of grips and grip forces by means of wireless signals generated by sensors worn on the feet or via other easy-to-use controllers.
Years of testing and optimization in collaboration with the Department of Veterans Affairs (VA) led to clearance by the U.S. Food and Drug Administration (FDA) and creation of a commercial-scale manufacturer, Mobius Bionics of Manchester, N.H. More than 100 people living with amputation were involved in initial studies, which led to a product whose natural size, weight, and shape provides unparalleled comfort and ease of use.
During the ceremony, VA Secretary David Shulkin presented LUKE arms to Fred Downs and Artie McAuley. Downs is a prosthetics consultant for the Paralyzed Veterans of America and retired Chief Procurement and Logistics Officer for the Veterans Health Administration who lost his left arm above the elbow during the Vietnam War.
McAuley is an Army veteran whose arm was amputated as the result of an accident while stationed at Fort Drum, N.Y. He went without a prosthesis for years because earlier-generation devices did not work well for individuals whose loss extended all the way up to the shoulder.
Throughout the Revolutionizing Prosthetics program, DARPA received contracting support from the Army Research Office. Additionally, U.S. Army Medical Research and Material Command provided funding to help complete the FDA approval process.
