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 Results may not be published yet.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.

Summary

This study tests whether a newer multi-tined electrode provides longer pain relief than a standard single-tip electrode during radiofrequency ablation for lumbar spondylosis, a common cause of lower back pain. About 25 adults with chronic lower back pain from worn facet joints will be randomly assigned to receive the procedure with one of the two FDA-approved devices. Researchers will track pain and daily function using patient questionnaires over 12 months to see if the larger lesion created by the multi-tined electrode leads to better outcomes.

What this could mean

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

Active substance
radiofrequency ablation device
What this could lead to
If the multi-tined electrode proves more effective, it could offer longer-lasting pain relief for people with chronic lower back pain due to lumbar spondylosis.
What could go wrong
This is a small, early-stage study with only 25 participants, so results may not apply to everyone. The procedure only provides temporary pain relief and does not cure the underlying condition.
