What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only

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 whether doing pulmonary rehabilitation in underground salt chambers improves breathing, exercise ability, and quality of life in people with COPD. 80 adults with stable COPD will be split into four groups: rehab in salt chambers, rehab in a gym, just sitting in salt chambers, or health education only. Researchers will measure changes in walking distance, symptoms, and muscle strength right after the 16-day program and again three months later.

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 in therapeutic salt chambers
What this could lead to
If it works, this could offer a new way to improve exercise tolerance and quality of life for people with COPD.
What could go wrong
This is a small, early-stage study with 80 participants. The benefits of salt chamber therapy are unproven, and results may not apply to all COPD patients.
