About this trial
This is a device study that will evaluate the effect of an implanted stimulator on improving walking in people with incomplete spinal cord injury. There are two phases in the study: 1) Screening - this phase determines if the individual is a good candidate to receive an implanted system, 2) Implantation, controller development, and evaluation - this phase includes implanting the device and setting the individual up for system use, creating controllers for walking, and evaluating the effect of the device over a couple years.
