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 Results may not be published yet.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 study will compare two non-invasive treatments—high-intensity laser therapy and extracorporeal shock wave therapy—for people with chronic supraspinatus tendinopathy (a common shoulder tendon condition). Researchers will measure tendon thickness, shoulder space, pain, range of motion, and hand strength in 69 adults aged 18 to 50. The goal is to find which therapy works better to ease symptoms and improve function.

What this could mean

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

Active substance
High-intensity laser therapy and extracorporeal shock wave therapy
What this could lead to
If this trial succeeds, it could show which non-invasive therapy better reduces tendon thickness and improves shoulder pain and function.
What could go wrong
This is a small, early-stage study with only 69 participants, so results may not apply to everyone. Both treatments are non-invasive but may not work for all patients.

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 69 people

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