What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting 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 Results may not be published yet.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.

Summary

This study will test whether adding a breathing muscle trainer to aerobic exercise helps adults with obesity and chronic low back pain. Forty-eight participants will be split into two groups: one using the trainer at a low resistance and one at a higher resistance. Researchers will measure lung function, exercise capacity, pain, and disability before and after six weeks of training.

What this could mean

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

Active substance
Inspiratory muscle trainer (POWERbreathe device)
What this could lead to
If it works, this could offer a simple, drug-free way to improve breathing, exercise capacity, and reduce pain in people with obesity and chronic low back pain.
What could go wrong
This is a small, early-stage trial with only 48 participants, and it has not started yet. The device may not provide meaningful benefits over standard exercise alone.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 48 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Mar 2026

An estimate. Start dates often move.

Expected to finish

Aug 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
