Recruiting studies
- NCT04959526Recruiting
Testing lung stiffness and breathing function in healthy adults
This study compares a lung ultrasound method (shear-wave elastography) with breathing function tests to see how well they match. It may help researchers better understand how to measure lung health using imaging versus breathing tests.
Rochester, MinnesotaAges 18 years+ - NCT06756633Recruiting
Breathing and movement study for neuromuscular disease
This study looks at breathing, chest and belly movement, and exercise ability in people with Duchenne Muscular Dystrophy or Spinal Muscular Atrophy, as well as healthy people. The goal is to compare these functions to help understand how these diseases affect the body.
Ankara, ÇankayaAges 5–15 - NCT07523919Recruiting
How fitness and breathing affect colorectal cancer recovery
This study looks at how your physical fitness and lung function may affect how well you do after colorectal cancer treatment. Researchers will test your strength, movement, and breathing to understand what helps people recover better long-term.
Merkez, Gümüşhane ProvinceAges 18–80 - NCT06793800Recruiting
Ear nerve stimulation to improve breathing after stroke
This study tests whether a gentle nerve stimulation device placed on your ear can improve your breathing after a stroke. It's for people who had a first stroke 1 to 3 years ago and are otherwise generally healthy (no heart, lung, or ear problems).
IstanbulAges 40–80 - NCT07521956Recruiting
Mindfulness training for recreational runners
This study tests whether a mindfulness program can help recreational runners improve their performance, breathing, and heart rate patterns. If you're a regular runner, this trial explores whether mental training alongside your running could enhance your physical abilities.
Chilliwack, British ColumbiaAges 19 years+ - NCT07352774Enrolling by invitation
Laughter therapy for breathing and pain in older adults
This study tests whether laughter therapy can improve breathing and reduce pain in people aged 60 and older. It may be a fun, drug-free way to feel better.
Ankara, AnkaraAges 60 years+ - NCT05756894Recruiting
Stimulation therapy to improve breathing after spinal cord injury
This trial studies a neurostimulation approach to help breathing problems after a spinal cord injury. You may be able to join if you have a certain type and level of spinal cord injury and breathing weakness, and you can safely attend study visits with caregiver support.
Chicago, IllinoisAges 18–85 - NCT07529301Recruiting
Lung Function Tests Before Surgery to Predict Recovery
This study measures your lung function and physical fitness before surgery to see if these tests can predict how quickly you'll recover. The researchers want to understand which patients might have an easier or harder recovery after their operation.
MalatyaAges 18–80 - NCT07670923RecruitingPhase 4
Comparing two sedatives for older patients during non-intubated surgery
This trial compares two sedative medicines, ciprofol and propofol, to see which works better for older patients having surgery without a breathing tube. It aims to find the safer option for your heart and lungs.
Yinchuan, NingxiaAges 65–80 - NCT06972784Recruiting
Heart and lung health study at Xiangya Hospital
This study looks at how heart and lung function are related over time. You may be able to join if you have had both a heart test (like an echo) and a lung test (like a breathing test) within one year of each other, and if your medical records are complete.
Changsha, HunanAges Any age - NCT05856136RecruitingPhase 4
Study how opioid exposure affects diaphragm muscle function
This study looks at whether receiving opioids for pain during lower-leg surgery changes how well the diaphragm muscle (the main breathing muscle) works afterward. It compares breathing muscle function in people who do and do not have certain lung conditions.
Rochester, MinnesotaAges 18 years+ - NCT07423338Recruiting
Monitoring breathing muscles in respiratory failure patients
This study tests a new way to monitor breathing muscles in patients who need extra oxygen or breathing support, like a mask or high-flow oxygen. It may help doctors better understand how to treat respiratory failure.
LondonAges 18 years+ - NCT05459116Recruiting
Record breathing effort to protect lungs during ventilation
This trial studies a way to measure how hard a patient is breathing and how the lungs and diaphragm are working while someone is on a breathing machine. The goal is to help the team use a “lung- and diaphragm-protective” ventilation strategy and see if it improves care.
Edegem, AntwerpAges 4 weeks+ - NCT07482930Recruiting
Nerve stimulation and breathing test study in healthy adults
This study tests if a gentle nerve stimulation device placed on the ear can change how you breathe during a lung function test. It is only for healthy volunteers aged 18–40 who have no heart, lung, nerve, or mental health conditions.
SinopAges 18–40 - NCT05193136Recruiting
Testing sleep and exercise effects on strength and thinking in lung disease
This trial studies whether improving sleep habits can help people with lung conditions like COPD or IPF maintain muscle strength and thinking (cognitive function). It may help by addressing sleep quality and related health factors, but eligibility depends on your current diagnoses and treatments.
Jōyō, KyotoAges 20 years+ - NCT06537362Recruiting
Comparing a new mouthpiece for breathing tests
This study tests a new mouthpiece with built-in cheek support during a standard breathing test called oscillometry. It may be more comfortable and easier to use than having someone hold your cheeks manually.
BergamoAges 5–75 - NCT07112703Recruiting
Breathing exercise study for children with thalassemia
This study tests if a breathing exercise device (incentive spirometer) can improve lung function and daily activity in children with thalassemia who receive regular blood transfusions. It aims to help them breathe easier and be more active.
ZagazigAges 6–10 - NCT07050069Recruiting
Breathing training for spinal cord injury patients
This study tests a new breathing exercise method combined with a gentle brain stimulation technique to help people with spinal cord injury improve their breathing and lung function. It may be an option if your injury is recent and at or above the mid-back level.
Shenyang, LiaoningAges 18–80 - NCT07051954Recruiting
Breathing muscle training for long COVID recovery
This study tests a special breathing and muscle training program to help people with long COVID feel better and move more easily. The training is designed to strengthen the muscles you use to breathe and to improve your daily function.
Ankara, ÇankayaAges 18–65 - NCT06611527Recruiting
Breathing therapy to improve lung function after heart surgery
This study tests a breathing treatment using mild air pressure after heart surgery to help your lungs work better and reduce complications. It may be an option for people at higher risk for lung problems or those with early breathing issues after surgery.
São Paulo, São PauloAges 18 years+ - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children
This study compares simple coughing exercises with a breathing device (incentive spirometry) to help children recover lung function faster after heart surgery. It may help reduce complications and shorten hospital stays.
Baghdad, Baghdad GovernorateAges 6–18 - NCT07629284Enrolling by invitation
Home-Based Breathing Therapy for Children With Duchenne Muscular Dystrophy
This study tests whether children with Duchenne muscular dystrophy (a genetic muscle-weakening condition) can improve their breathing strength and function by doing guided exercises at home using video calls with a therapist. The goal is to help children breathe better and stay as active as possible.
Seoul, SeoulAges 3 years+ - NCT06490744Recruiting

Common questions
- Are there clinical trials for respiratory function?
- Yes. Clin2 currently lists 75 recruiting respiratory function studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a respiratory function trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a respiratory function trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
