Intervention type: COMBINATION_PRODUCT
Group type: EXPERIMENTAL
Intervention: Epidural stimulation + Stand Training
Description: Participants may use a standing apparatus or a less assistive device such as walker or cane. In case of upper limbs and trunk control insufficient for safely using the standing apparatus, participants will be placed on the treadmill, and a body weight support system. In this case, the level of body weight support will be continuously reduced as the individuals increase their ability to bear weight. A trainer positioned behind the participant will aid in pelvis and trunk stabilization. Trainer(s) positioned at the lower limb will provide manual facilitation for knee extension during standing. Manual facilitation at the trunk-pelvis and at the legs will be used only when needed.Participants will be encouraged to stand for as long as possible throughout the training session, with the goal to stand for 60 minutes with the least amount of assistance.

Intervention: Epidural stimulation + Step Training
Description: Participants may be placed on the treadmill in an upright position and suspended in a harness. All trainers are careful to provide manual assistance only when needed. A trainer positioned behind the research participant will aid in pelvis and trunk stabilization, as well as appropriate weight shifting and hip rotation during the step cycle. Trainers positioned at each limb will provide manual assistance to promote knee extension and knee flexion and toe clearance. Research participants will step at various body weight load and speed. Research participants will take a break and rest at any time they feel the need to during the session. If independence is achieved during stepping, some training might be performed overground with appropriate assistive device and manual assistance to maintain participant safety. Participants will be encouraged to step for 60 minutes with the least amount of assistance. Seated or standing resting periods will occur when requested by the individuals

Intervention: Epidural stimulation + Bladder Capacity Training
Description: We will initially conduct daily training for capacity in a supervised on-site lab setting. Optimal configurations will be used. The storage phase configuration will be used until the time for voiding/catheterization. The training procedure will be repeated for up to 8 hours daily on-site until three consecutive stable days of maintaining a consistent capacity values are achieved and deemed safe. In the home setting, participants will record blood pressure values, voided and residual volumes. Participants will return to the lab the following day for monitoring and testing. If assessments show stable outcomes, participants will be allowed to train at home for 7 consecutive days, prior to returning to the lab for clinical evaluation (urodynamics and questionnaires). On the return visit, if their storage/voiding outcomes remained stable over the 7 days, they will be able to start the home-based training for bladder capacity.

Intervention: Epidural stimulation + Bladder Voiding Efficiency Training
Description: We will conduct training for voiding efficiency in a supervised on-site lab setting while the participant continues his/her training for capacity. Voiding without catheterization will be attempted. The training procedure will be repeated for up to 8 hours on-site until three stable days of maintaining a consistent voiding efficiency are achieved and deemed safe. The participant will be sent home for one day to perform the stimulation at home. In the home setting, participants will record blood pressure values, voided and residual volumes. Participants will return to the lab the following day for monitoring and testing. If assessments show stable outcomes, participants will be allowed to train at home for 7 consecutive days, prior to returning to the lab for clinical evaluation and questionnaires. On the return visit, if their storage/voiding outcomes remained stable over the 7 days, they will be able to start the home program integrating bladder training for capacity and voiding
