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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 looks at how muscles around the knee work together after anterior cruciate ligament (ACL) reconstruction surgery. Researchers will measure muscle strength and electrical activity during movement in 30 adults who are 4 to 12 months post-surgery. They will also use questionnaires to assess knee confidence and fear of movement. The goal is to identify different neuromuscular profiles that could inform personalized rehabilitation.

What this could mean

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

Active substance
Neuromuscular and patient-reported assessments including surface electromyography and questionnaires
What this could lead to
If successful, this could help tailor rehabilitation programs to individual neuromuscular profiles after ACL reconstruction.
What could go wrong
This is a small, exploratory study, so findings may not apply to all patients. It does not test a treatment, so it will not directly change care.
