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 Results may not be published yet.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

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 a digital exercise program that adapts in real time to help children aged 6 to 12 recover after congenital heart disease surgery. Kids wear a monitor and get personalized exercise prompts and feedback. Researchers will compare their recovery to children receiving standard care, looking at fitness, heart function, and how well they stick with the program.

What this could mean

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

Active substance
Just-in-Time Adaptive Intervention (JITAI)-based digital exercise rehabilitation program
What this could lead to
If successful, this could provide an effective, personalized digital rehab tool to help children recover faster and more comfortably after heart surgery.
What could go wrong
This is an early-stage study with only 130 participants, so results may not apply to all children. The digital program may not work better than standard care, and some children may find it difficult to follow.
