About this trial

This trial is enrolling up to12 individuals with chronic cervical spinal cord injury to test the feasibility of implanting small electrodes in the parts of the brain that control movement and sensation; that procedure will be combined with surface electrodes on the upper arm and shoulder that activate paralyzed muscles of the arm and hand using signals from the brain electrodes. Investigators call this reHAB (Reconnecting the Hand and Arm to the Brain). If included, participants will undergo surgery for implantation of the brain electrodes. Testing will assess participants' ability to control the position of a cursor on a monitor using the recorded neural signals. The study lasts 13 months; participants can then opt to remain in a long-term (5 year) study.
