We developed a brain machine interface (BMI) that allows monkeys to pick up and move objects despite a peripheral nerve block causing complete paralysis of the flexor muscles below the elbow. Such a system might ultimately provide spinal cord injured patients with control of arm and hand movements through normal cognitive processes. However, a major issue to be addressed in the development of more effective BMIs is restoring the somatosensory feedback that is also lost in spinal cord injury. Proprioception is essential for normal movement. Its loss largely eliminates the ability to plan movement dynamics or to make rapid corrections to limb perturbations. Although some progress has been made toward restoring touch through intracortical microstimulation (ICMS), there has been as yet, little corresponding success for proprioception.
