Spinal zap plus robot arm training shows promise for hand movement
NCT ID NCT07432321
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small pilot study tests whether adding a gentle electrical stimulation to the spinal cord (tSCS) can make robotic arm training more effective for people with chronic tetraplegia from a spinal cord injury. Six to eight adults with neck-level injuries will first receive robotic training alone, then robotic training plus stimulation. Researchers will measure changes in arm strength, sensation, and quality of life. The goal is to see if the combination leads to better hand and arm function.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. At least 6 months to 5 years from the diagnosis of the traumatic SCI; 2. Participants between 21 and 80 years of age; 3. C2-8 level injuries; 4. ISNCSCI-UEMS \>25, 5. Pinch force \> 25 N; 6. Grasp force \> 100 N; 7. Able to perform the box and block test; 8. Sitting tolerance for at least 1 hour (No known postural hypotension issues or pressure intolerance); 9. Capable of providing an informed consent; 10. Cleared by Neurosurgeons/Orthopaedic Surgeon for tSCS; Exclusion Criteria: 1. Participant has uncontrolled cardiopulmonary disease or cardiac symptoms as determined by the investigator. 2. Participant has any unstable or significant medical condition that is likely to interfere with study procedures or likely to confound performance and outcomes like uncontrolled neuropathic pain, depression, severe cognitive impairment. 3. Unstable or uncontrolled autonomic dysreflexia. 4. Requires ventilator support. 5. Spasms that limit the ability of the subjects to participate in the study training as determined by the investigator. 6. Has an autoimmune etiology of spinal cord dysfunction/injury 7. History of additional neurologic disease, such as stroke, multiple sclerosis and traumatic brain Injury. 8. Pain in shoulder and/or hand which will be inhibitory towards rehabilitative therapy. 9. Severe Upper limb contractures. 10. Acute Medical conditions to Upper limb (ie Fractures that would limit ROM and/or weightbearing). 11. Participants who are pregnant.
