What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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

Summary

This trial compares two minimally invasive procedures—traditional bipolar radiofrequency and cooled radiofrequency—for treating chronic sacroiliac joint pain, a common cause of lower back pain. Adults aged 18-70 with persistent SI joint pain that hasn't improved with conservative care may participate. The study measures pain intensity and functional disability to see if one technique offers better or longer-lasting relief.

What this could mean

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

Active substance
Cooled radiofrequency and traditional bipolar radiofrequency procedures
What this could lead to
If successful, this could show that cooled radiofrequency provides longer-lasting pain relief and better function for people with sacroiliac joint pain, potentially becoming a preferred treatment option.
What could go wrong
This is a relatively small trial, and results may not apply to everyone. Both procedures carry risks like infection, bleeding, or nerve damage, and pain relief may not be permanent.

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 70 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Lead sponsor

Other sponsor
