 Following discharge from inpatient or recovering at home the individuals will be seen at Frazier Rehab Institute on a daily basis for testing and LT. We will evaluate the combination of epidural stimulation with manual stepstand training. This stage will be conducted over six-eight months. During training, the patients will be provided with epidural stimulation using the parameters defined in Stage 1. Testing FNPA, MEP, SSR and efferent motor activity may be performed weekly.
