Advancements in prosthetic-limb research soon could lead to a new generation of devices that would provide sensory feedback to amputees and quadriplegics. The Reliable Neural-Interface Technology, developed by Defense Advanced Research Projects Agency (DARPA), uses improved interfaces that link the artificial limbs with nerves and muscles. They also can be attached using less invasive procedures than the present generation of interface-capable prosthetics, DARPA stated in a May 30 release. The devices currently are undergoing tests on quadriplegics. "Practical applications of brain interfaces for amputees are still in the future," DARPA stated. DARPA is conducting the project in conjunction with researchers at the Rehabilitation Institute of Chicago and Case Western Reserve University in Cleveland.
