Can a 20-Minute brain zap ease nerve pain?
NCT ID NCT06029075
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small study tests whether a gentle, non-invasive brain stimulation technique called tACS can reduce nerve pain in people with spinal cord injury. Fourteen participants will receive either real or sham stimulation for 20 minutes. Researchers will measure pain levels and heart rate changes to see if the treatment helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial alternating current stimulation (tACS) device
- What this could lead to
- If it works, this could point toward a drug-free way to manage chronic nerve pain after spinal cord injury.
- What could go wrong
- This is a very small, early study with only 14 people, so results may not apply widely. The effect on pain is uncertain and may be no better than a placebo.

Inclusion/exclusion criteria for SCI subjects Inclusion criteria: A patient who 1. has neuropathic pain after traumatic spinal cord injury or amputation or brain injury; 2. has chronic pain, \>3 months; 3. is between 18 to 75 years of age; 4. is stable on oral pain medications at least two weeks. Patients are allowed to continue their pain medications, i.e., no change in pain medications. NOTE: we plan to begin the study with the spinal cord injury (SCI) subject population as a cohort first, then expand to other subject populations Exclusion criteria: Patients will be excluded if they 1. are currently adjusting oral pain medications for their neuropathic pain; 2. have pain, but not neuropathic, e.g., from inflammation at the incision wound of the residual limb or neuroma; 3. have a pacemaker metal implants or supplemental oxygen; 4. have amputation in their arm(s); 5. fail to have a motor contraction in the arm muscles with TMS; 6. are not able to follow commands, or to give consent; 7. have asthma or other pulmonary disease; 8. are not medically stable; 9. have preexisting psychiatric disorders; 10. alcohol or drug abuse.
