 After completion of these evaluations, participants will undergo 80 sessions of stepstand training. The investigators will repeat the FNPA, NCS, SEP, SSR, reflexes, bladder function, CV function and assessment of the efferent motor activity during standing and stepping after the completion of the 80 training sessions to quantify that no motor pattern changes are achievable with LT alone. Drs. Harkema, Williams, Park and Boakye will meet to discuss the results of the preliminary testing and evaluate if the participant is eligible for surgical implantation for SCES.
