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 Results may not be published yet.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.

Summary

This study tests whether doing a specific knee exercise with a metronome (a device that makes regular beeps) can improve how the thigh muscle works in athletes who recently had ACL reconstruction. 40 participants will do one session of the exercise, with or without the metronome. Researchers will measure muscle signals to see if the metronome helps control the muscle better.

What this could mean

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

Active substance
audible cues (metronome) during exercise
What this could lead to
If it works, this could point toward a simple, low-cost way to improve knee muscle recovery after ACL surgery.
What could go wrong
This is a very small, early study with only 40 people and a single exercise session. It measures immediate muscle signals, not long-term recovery or function.
