Researchers are working on a noninvasive brain-machine interface to a robotic orthotic device that could help rehabilitate upper-limbs. The new neurotechnology will interpret brain waves that let a stroke patient operate an exoskeleton that wraps around the arm from the fingertips to the elbow. A similar device already is used to treat spinal-cord injury patients. Rice University, the University of Houston (UH) and TIRR Memorial Hermann are working on the device with the help of a $1.17 million grant from the National Institutes of Health and the President's National Robotics Initiative.
