Testing treatment for sleep breathing problems in people on opioids
This trial studies a treatment approach for sleep-disordered breathing (breathing problems during sleep) in Veterans who take prescription opioids. It may help doctors learn safer ways to manage sleep breathing issues that can be made worse by opioid use.
Detroit, MichiganAges 18–89 - NCT05456009Recruiting
Breath analysis test for adults
This study tests how analyzing your breath can help researchers detect or understand health conditions. If you’re an adult and can safely participate, you may be able to take part and have your exhaled breath measured.
Zurich, Canton of ZurichAges 18 years+ - NCT05341726Recruiting
Test a program to improve asthma control in Black adults
This study tests an approach that combines education and support to help adults with uncontrolled asthma manage their symptoms better and use treatments correctly. It focuses on Black adults receiving care at specific community health clinics.
Beacon, New YorkAges 18 years+ - NCT04971850Recruiting
Sleep study for children with possible breathing sleep problems
This trial looks at sleep-related breathing problems (“sleep-disordered breathing”) in children and young adults and how they may affect thinking and memory using sleep study testing plus neurocognitive (thinking) assessments. It may help doctors better understand symptoms and identify who could benefit from treatment.
ParisAges 1–20 - NCT03422302Recruiting
CPAP or breath-holding to reduce lung tumor motion
This study looks at whether using a CPAP breathing device or deep breath-holding can keep lung tumors from moving during targeted radiation. The goal is to improve safety and accuracy of stereotactic body radiation for lung cancer.
Houston, TexasAges 18 years+ - NCT03233256Enrolling by invitation
Breath and saliva tests in healthy adults
This study measures substances in your breath and saliva to understand what can be detected from the body. You might help by providing samples, as long as you’re generally healthy and meet the study’s age and health requirements.
Aurora, ColoradoAges 18–45 - NCT02851043Recruiting
Non-invasive monitor to measure breathing
This study tests a device that checks breathing without needles or painful procedures. It may help doctors learn how well breathing can be measured in people with mild breathing problems, or in healthy volunteers.
Wilmington, DelawareAges 11–17 - NCT07501637Recruiting
Mind-body group support for young breast cancer survivors
This study tests a mind-body group program to help young breast cancer survivors manage stress and emotional distress. It includes a virtual workshop, weekly group sessions, and daily practices to improve well-being.
Birmingham, AlabamaAges 18–50 - NCT05946512Recruiting
Yoga breathing plus lung MRI measurements for post-COVID symptoms

Biofeedback exercises versus Mulligan method for neck pain
This trial compares two non-surgical treatments for ongoing neck pain: biofeedback exercises, which use sensors to help you learn to relax and strengthen neck muscles, and the Mulligan method, a hands-on technique that improves movement and posture. It aims to see which is better for reducing pain, improving mobility, and correcting posture in women.
