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 Results may not be published yet.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

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 investigates whether adding a contract-relax physical therapy technique to standard respiratory care can improve diaphragm function in patients who develop diaphragmatic paresis after cardiac surgery. The trial enrolls adults who have undergone heart surgery with a heart-lung machine and show diaphragm weakness on ultrasound. Participants receive either usual physical therapy or usual therapy plus the contract-relax technique, and diaphragm movement is measured at day 3 and day 5 after surgery.

What this could mean

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

Active substance
Contract-Relax physical therapy technique
What this could lead to
If effective, this technique could become a standard addition to respiratory therapy, helping patients recover diaphragm function faster after heart surgery.
What could go wrong
This is a small, early-stage study with only 27 participants. The technique may not provide significant benefit over usual care, and results may not apply to all patients.
