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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether two types of percutaneous electrolysis (simple or multifilar) or laser therapy better relieve pain and improve shoulder movement in people with supraspinatus tendinopathy, a common cause of shoulder pain. Participants receive one treatment session and are evaluated before, right after, 24 hours, and one week later. The goal is to find which technique offers faster and 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
percutaneous electrolysis (simple or multifilar) and laser therapy
What this could lead to
If one method proves superior, it could offer a more effective, non-surgical option for treating chronic shoulder tendon pain.
What could go wrong
This is a small, early-stage trial with only 60 participants, so results may not apply broadly. The invasive electrolysis procedure carries minor risks like pain or infection.
