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 Results may not be published yet.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

Summary

This study tests whether drinking a protein beverage after leg-strengthening exercises helps stroke survivors rebuild muscle better than exercise alone. About 93 people who had a stroke more than 3 months ago will take part. Researchers will measure changes in thigh muscle size, strength, and walking ability.

What this could mean

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

Active substance
protein supplement
What this could lead to
If it works, this could point toward a simple way to help stroke survivors regain muscle and function through exercise plus protein.
What could go wrong
This is a small, early-stage study with only 93 participants, so results may not apply to everyone. The protein drink may not provide extra benefit over exercise alone.
