Read our COPD research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether a device called the Breather — which strengthens your breathing muscles — can help people who have both COPD (chronic lung disease) and pain in their legs when walking. Researchers know that people with COPD are at higher risk for poor circulation in their legs, which causes leg pain during activity. This trial will see whether using the Breather device along with treadmill walking and breathing exercises over 4 weeks can improve both your lung function and your leg circulation.
Many people with COPD also develop poor blood flow to their legs, which limits how far they can walk before leg pain stops them. Breathing exercises have shown promise in helping people with COPD, but it's unclear whether strengthening your breathing muscles with a device like the Breather can also help improve circulation and reduce leg pain.

You will visit the study center 3 times per week for 4 weeks. During each session, you will walk on a treadmill for 20 minutes and use the Breather device (a handheld breathing trainer) for 3 to 5 sets, along with practicing slow breathing exercises. Half of participants will receive the full treatment with the Breather device, while the other half will do the treadmill walking and breathing exercises without the device. Researchers will measure your breathing strength, lung function, and leg circulation before and after the 4-week program.
