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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers at Pamukkale University are studying overhead athletes, such as throwers and swimmers, to see whether differences between the dominant and non-dominant arm relate to injury and performance. About 58 athletes aged 15 and older who train and compete regularly take part. Participants complete four physical tests: a medicine ball forward throw, an upper-body Y balance test, shoulder rotation range-of-motion measurements, and rotator muscle strength testing with a dynamometer.

What this could mean

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

Active substance
a battery of physical tests measuring shoulder range of motion, rotator muscle strength, balance, and medicine ball throw distance
What this could lead to
If the tests reveal a clear link between limb asymmetry and injury, coaches and clinicians could use simple sideline measurements to flag athletes at higher risk and tailor training to even out the differences.
What could go wrong
This is a small observational study of 58 athletes, so it can show associations but not prove that asymmetry causes injury. Results may not apply to all overhead sports or age groups, and testing only captures a snapshot in time.
