An interventional study of Activity based upper extremity training with and without stimulation in Spinal Cord Injury Cervical, sponsored by University of Louisville. Enrolling by invitation at 1 site in United States. Open to participants aged 7 Years to 12 Years. Per ClinicalTrials.gov, last updated 2026-02-18.

The main goal of this pilot study is to find the best ways to use transcutaneous spinal cord stimulation (scTS) to improve hand function in children with spinal cord injuries (SCI). The investigators will start by exploring the best places and strengths for applying scTS on the neck, the added benefits of applying scTS on the lower back (T11-T12), and comparing the effects of using activity based upper extremity training (a control treatment) alone versus combining it with scTS to help children with chronic SCI regain hand function.
After learning about the study and potential risks, parents/legal guardians and their eligible children with SCI will sign consent and assent forms, respectively. For the first two aims of the study, the investigators will recruit and enroll 10 participants. In the first week, participants will undergo clinical assessments from day 1 to day 4 to categorize the severity and level of their injuries and assess their current arm and hand function. On day 5, eligible participants will have experimental assessments to measure hand grip and control, both with and without spinal cord stimulation (scTS) at one or two neck sites optimized to improve hand grip. On day 6, participants will have similar assessments, this time adding stimulation to the trunk area to help with upright sitting and study its impact on hand grip and control.
For the third aim, 4 participants who showed improved hand grip and control with stimulation in aims 1 and 2 will be selected on a first-come, first-served basis. They will undergo 20 sessions of activity-based upper extremity training, followed by 20 more sessions with the optimal stimulation sites identified from aims 1 and 2. After completing the training, participants will be asked to follow up and repeat experimental and clinical assessments to determine how long the improvements last.

Exclusion Criteria:
For all 3 aims will include:
Activity-based upper extremity training (AB-UET) will be administered 5d/week and 1 hour 30 minutes/session.
Device: Activity based upper extremity training with and without stimulation
Activity-based upper extremity training (AB-UET + scTS) will be administered 5d/week and 1 hour 30 minutes/session. UE tasks will be repeated with and without scTS so that scTS is administered intermittently for the duration of \~ 10 minute/bouts.

Peak to peak distance on hand grip force
Time frame: 12 weeks
Functional neurophysiological assessment-Upper extremity
Multi-muscle activation patterns
Time frame: 12 weeks
Pediatric Neurorecovery scale
Pediatric Neurorecovery scale (NRS) is a validated clinical scale that assesses a child's (age 1-12 years) neuromuscular capacity to perform everyday tasks without behavioral compensation, physical assistance, or assistive device. The total score is the sum of all tasks on a scale from 1-12. For a total of 12 items, the highest score being 144 and lowest a sore of 12. Higher scores indicate improved function.
Time frame: 12 weeks
Capabilities of upper extremity test
The Capabilities of the Upper Extremity Test (CUE-T) is a performance measure intended to assess upper extremity function following spinal cord injury. The CUE-T is an objective measure of the ability to complete actions and tasks involving the arm and hand in individuals with tetraplegia and can be used clinically, for research and in clinical trials. Respondents answer questions on a 7-point scale that represents their self-perceived difficulty in performing the action, with 1 indicating "totally limited, can't do at all" and 7 indicating "not at all limited". The total score is the sum of all responses, and ranges from 32 to 224, with higher scores indicating greater function.
Time frame: 12 weeks
Box and block test
The Box and Block Test (BBT) measures unilateral gross manual dexterity and is validated in pediatric population. The score is the number of blocks carried from one compartment to the other in one minute. Each hand is scored separately. Higher scores within 1-minute indicate better manual dexterity.
Time frame: 12 weeks
