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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 will test whether a pulmonary rehabilitation program that includes inspiratory muscle training (using a device called Powerbreathe) can improve diaphragm function in people with COPD. Researchers will use ultrasound to measure diaphragm movement and thickness before and after the program. The goal is to see if these exercises help reduce symptoms like shortness of breath and fatigue. The study plans to enroll 46 adults aged 40 and older with stable COPD.

What this could mean

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

Active substance
Pulmonary rehabilitation with inspiratory muscle training (Powerbreathe device) and resistance/aerobic exercise
What this could lead to
If successful, this could show that combining inspiratory muscle training with standard rehab improves diaphragm function and reduces symptoms like shortness of breath in COPD patients.
What could go wrong
This is a small, early-stage study (46 participants) that is not yet recruiting. It focuses on measuring changes, not on proving a new treatment works, so results may not lead to a new therapy.
