Summary

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.

Detailed description

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.

Conditions

• Spinal Cord Injury Cervical

Interventions

Type	Name	Description
DEVICE	Activity based upper extremity training with and without stimulation	Activity-based upper extremity training (AB-UET) will be administered 5d/week and 1 hour 30 minutes/session. For AB-UET+ stimulation (scTS), UE tasks will be repeated with and without scTS so that scTS is administered intermittently for the duration of \~ 10 minute/bouts.
