What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 14 people

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
