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 Results may not be published yet.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.

Summary

This study uses a special thermal camera to take pictures of the feet of people with complex regional pain syndrome (CRPS) before and after they receive spinal cord stimulation. The goal is to see if the stimulation changes blood flow and temperature in the painful limb. Researchers will also ask participants about their pain levels. Only 12 people will take part, and the study does not test a new drug or treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could show that thermal imaging is a useful tool to measure how well spinal cord stimulation works for CRPS.
What could go wrong
This is a very small observational study with only 12 people. It is not testing a new treatment, just a measurement method, so it may not lead to direct patient benefits.
