Transcutaneous Spinal Cord Stimulation in Children with Incomplete Spinal Cord Injury
- Conditions
- Spinal Cord Injuries
- Interventions
- Other: Gait training with/without TSCS
- Registration Number
- NCT06242873
- Brief Summary
Aim 1: Determine the safety and feasibility of administration of TSCS to children in a clinical setting. Participants will be randomly assigned to experimental (TSCS) or control (sham stimulation) groups. Both groups will receive eight-weeks of individualized gait training. We will measure adverse events, including pain and skin irritation, to determine safety as the primary outcome. Hypothesis 1: Administration of TSCS to children in a clinical setting will be safe based on similar safety outcomes as sham TSCS. Hypothesis 2: TSCS is feasible based on compliance to session interventions and long-term adherence to the protocol. Additionally, we will collect data on effort during sessions of both participant and therapist. We anticipate that the participants will report less effort in the experimental condition, as compared to the control and therapists will report equal effort across conditions.
Aim 2: Determine the neurophysiologic impact of TSCS within a single session. We hypothesize that participants will demonstrate increased volitional muscle activity and strength with TSCS as compared to sham stimulation. This will be assessed by surface EMG and hand-held dynamometry of the dominant-side quadriceps muscle during maximum volitional contraction (MVC), across multiple time points. Changes in EMG activity will indicate change in central excitability in response to stimulation.
Aim 3: Exploratory measurement of TSCS and gait training on walking function. We hypothesize that concurrent TSCS and gait training will augment walking function in children with iSCI, as compared to gait training with sham stimulation. In addition to outcomes defined above, participants will be assessed with clinically relevant outcome measures, to include the Timed Up and Go, 10-Meter Walk Test, Walking Index for Spinal Cord Injury II, and 6-Minute Walk Test. Data collected as part of this aim will elucidate trends in responder qualities and timeline of changes to inform future studies.

Group Intervention Description Transcutaneous Spinal Cord Stimulation and Gait Training Gait training with/without TSCS Transcutaneous Spinal Cord Stimulation (TSCS), TSCS will be applied using an oval electrode placed midline on the skin on the back and two rectangular electrodes placed on the skin over the lower abdomen. There will be a small electrical current through those electrodes for 30 minutes. Transcutaneous Spinal Cord Stimulation within a single session Gait training with/without TSCS Electrodes will be placed as they are in the Transcutaneous Spinal Cord Stimulation condition. Stimulation will be applied at subject's maximum intensity for 30 seconds and then discontinued.
