Detailed Description
While the investigators have demonstrated the benefits of scES in chronic SCI with one of the largest series (23 patients to date) the investigators are acutely aware of persistent gaps that need to be filled in order to advance the field of neuromodulation forward. Technological advances to upgrade the stimulator's programming and wireless communication platforms are critically needed in order to integrate multiple training paradigms across multiple systems (i.e. motor and autonomic), as well as take advantage of wireless monitoring technology that could improve the patient experience. The extensive patient self-monitoring, for example regular monitoring of blood pressure during bladder filling cycles, and required manual interaction with the programming device to change parameters for optimal stimulation, remains one of the largest limiting factors in the effective utilization of this technology outside of the laboratory. Without technology components developed specifically for individuals with SCI, treatment effects could be lost due to the burden placed on the individual. Our aim is to develop technology that will interact with currently available systems, to facilitate the implementation and integration of training paradigms for the recovery of locomotion and bladder function in individuals with acute SCI and promote safe long-term use of the technology in the home and community. To this end, this study will provide a flexible communication platform specific for SCI, allow for the evaluation of integrated technology in individuals with high plasticity potential (< 1 year post injury) and allow for the longitudinal evaluation of therapeutic benefits of scES as individuals transition from acute to chronic phase of injury.
Aim 1: To evaluate the use of position based sensors internal to the neurostimulator to modulate stimulation parameters used in the training for motor function recovery following severe SCI.
Aim 2: To identify the scES parameters, using physiological feedback (continuous measures of systolic and diastolic pressure and heart rate), that improve bladder storage and emptying while controlling blood pressure following severe SCI.
Aim 3: To improve device technologies and develop predictive learning algorithms that will allow for the integration of multiple training paradigms used by a single participant.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Locomotion
Participants will receive 160 locomotor training sessions with epidural stimulation.
These sessions may occur once a day (stand and step will alternate days) or twice a day (stand and step on the same day) as recommended by the study physician.
Participants will train 5 days per week and each session will last between 1 to 1.5 hours.
|
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.
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
|
Experimental: Bladder+Locomotion
Participants will receive 80 sessions of bladder training alone followed by 80 sessions of locomotor training sessions with epidural stimulation.
They will be asked to continue with your bladder training once you start locomotor training.
Locomotor Training sessions may occur once a day (stand and step will alternate days) or twice a day (stand and step on the same day) as recommended by the study physician.
Participants will train 5 days per week and each session will last between 1 to 1.5 hours.

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.
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
