Breathing, diaphragm ultrasound, and muscle in COPD
Part of Lungs & breathing clinical trials.
This study compares breathing tests, ultrasound of the diaphragm, and muscle mass in healthy people and people with stable COPD. It aims to better understand how COPD affects the diaphragm and overall muscle health.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a healthy volunteer age 40 or older (Group A), or you have stable COPD and your last flare-up was at least 6 weeks ago (Group B).
- You do not have muscle, nerve, or bone problems that affect your breathing.
- You do not have a diaphragm problem (like eventration or hernia).
- You are not severely obese and have not had recent chest or belly surgery.
- You are not pregnant and do not have a lung-scarring condition (like pleurodesis or fibrothorax).

This trial studies how well your diaphragm (the main breathing muscle) works during a severe COPD flare, using an ultrasound scan. It may help doctors better assess breathing muscle performance when COPD symptoms suddenly worsen.
This study uses ultrasound to measure how well your diaphragm muscle works during a COPD flare-up. The goal is to see if this measurement can help predict how you will recover.
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
This study looks at the strength and flexibility of muscles you use to breathe, including muscles in your chest and neck. If you have moderate-to-severe COPD and have been stable on your medications, it may help researchers understand how these muscles are affected.
This study looks at how the diaphragm (the main breathing muscle) and the drive to breathe work in people with sleep apnea, COPD, or both. Researchers want to compare these groups with healthy volunteers to better understand breathing problems.
This trial is testing how well a simple ultrasound can measure diaphragm (breathing muscle) function in people with COPD who are using a breathing mask (non-invasive ventilation). The goal is to see if this measurement can predict how well someone will recover from a COPD flare-up.
