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 Results may not be published yet.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

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 compares two methods of pulsed radiofrequency treatment for the suprascapular nerve in people with chronic shoulder pain from rotator cuff problems. Thirty-two adults aged 40 to 80 will be randomly assigned to receive the treatment at either the suprascapular notch or a midpoint approach. Researchers will measure pain, shoulder function, muscle strength, and quality of life over three months to see which approach works better.

What this could mean

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

Active substance
pulsed radiofrequency treatment
What this could lead to
If successful, this study could show which approach (notch or midpoint) works better for reducing pain and improving shoulder function in people with chronic shoulder pain.
What could go wrong
This is a small, early-stage trial with only 32 participants, so results may not apply to everyone. The treatment is for symptom relief, not a cure, and benefits may be modest or temporary.
