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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two supervised exercise programs—motor control retraining and close kinetic chain exercises—to see which better reduces pain, improves knee function, and strengthens a key thigh muscle in people with patellofemoral pain syndrome (pain around the kneecap). Fifty adults aged 18 to 40 with this condition will be randomly assigned to one of the two programs, attending 45-minute sessions three times a week for six weeks. Researchers will measure pain, knee function, muscle strength, and knee alignment to determine which approach offers greater benefits.

What this could mean

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

Active substance
Motor control retraining exercises and close kinetic chain exercises
What this could lead to
If one exercise approach proves more effective, it could give physiotherapists a clearer, evidence-based choice for treating patellofemoral pain syndrome.
What could go wrong
This is a small, early-stage trial with only 50 participants, so results may not apply to everyone. Exercise programs depend on adherence, and outcomes may vary.
