Researchers want to understand how the diaphragm—your main breathing muscle—works differently in people with various lung diseases. By measuring your breathing muscle strength and function during one visit to their lab, and then checking in with you by phone over 18 months, they hope to discover whether diaphragm problems can predict who might need hospitalizations or steroid treatments in the future.
Many people with lung diseases feel short of breath, but doctors don't yet have a reliable way to predict which patients will get worse or need emergency care. This study aims to fill that gap by testing whether measuring breathing muscle function could become a useful tool to spot patients at higher risk.

You will visit the research lab for one day, where the team will perform non-invasive tests to measure how well your breathing muscles work, check your lung function, and assess your exercise tolerance. You'll also complete questionnaires about your symptoms. After that, the researchers will call you by phone at 3, 6, 12, and 18 months to check on your health and ask whether you've had any hospitalizations or needed steroid treatments. If you're part of a smaller subgroup or have started a new approved medication, you may be invited back to the lab once or twice to repeat the breathing muscle tests in person.
