Ghent, East-FlandersAges 18–110 - NCT05000515Recruiting
Breathing muscle training to lower blood pressure in postmenopause
This study compares a breathing-based exercise program with regular aerobic exercise to help lower blood pressure and improve blood vessel function in postmenopausal women. It’s mainly for people with mildly elevated resting blood pressure who are not already doing very intense workouts.
Boulder, ColoradoAges 50 years+ - NCT05005793RecruitingPhase 4
Alkali treatment to improve kidney graft blood vessel function
This trial tests whether adding an “alkali” treatment (to raise low blood bicarbonate) can improve blood vessel and kidney graft function in people whose kidney transplant is about 1 year old. It may help if you have lower-than-normal bicarbonate levels while on stable transplant and blood pressure medicines.
Aurora, ColoradoAges 18–80 - NCT05009433Recruiting
Exercise plans in pregnancy and afterward for mom and baby health
This study compares two types of exercise—short, intense intervals versus moderate steady activity—during pregnancy and looks at effects on mothers and children. It also checks how participants do on health, fitness, and well-being tests before, during, and after pregnancy.
Gdansk, Pomeranian VoivodeshipAges 18–45 - NCT05010109Recruiting
Testing heart safety and fitness during lung cancer chemoradiation
This study looks at how lung cancer treatment affects the heart and whether a “walking test” and blood tests can track heart fitness and injury. It may help by improving how cancer therapy is planned and monitored for heart safety.
Houston, TexasAges 18 years+ - NCT05014178Recruiting
Kidney salt imaging scan with MRI
This study uses an MRI scan to look at how your kidneys handle salt (sodium). It may help researchers better understand kidney function in healthy people and in people with chronic kidney disease.
London, OntarioAges 18 years+ - NCT05022940Recruiting
Track recovery and participation after adult brain injury rehab
This study follows adults with traumatic brain injury (TBI) during and after rehabilitation, to better understand how recovery and daily participation change over time. It may help improve rehab programs for people like you in the future.
Montreal, QuebecAges 17 years+ - NCT05023434Recruiting
Brain stimulation study for hand strength in brain tumor patients
This study uses brain stimulation during surgery to see how it affects hand strength and hand function. It may help doctors understand which brain areas are important for hand movement in people with certain brain tumors.
Milwaukee, WisconsinAges 18–75 - NCT05025774Recruiting
Exercise program study for young heart, leukemia, and lung survivors
This study looks at how an exercise program affects fitness and lung function in young people who are survivors of certain conditions (heart transplant, leukemia, or lung disease from prematurity). The goal is to see whether exercise can improve breathing and overall physical function safely.
Minneapolis, MinnesotaAges 8–25 - NCT05028712Recruiting
Multi-sensory rehab program for people with ultra low vision
This trial tests a rehabilitation program using multiple senses to help people with very low vision function more independently. It may help you learn new skills for daily life by using vision plus other senses.

Dupilumab to improve sleep and itch in children with eczema
This trial studies whether dupilumab can improve daily body clock (circadian function), sleep, and itching in children with moderate-to-severe eczema that isn’t well controlled by creams. It may help kids who are having significant sleep trouble and ongoing itch.
Chicago, IllinoisAges 6–17 - NCT05042219Recruiting
How lung disease treatment may affect heart function
This study looks at how common long-term lung conditions and their treatments may change heart function. It uses heart imaging (an MRI) to see what’s happening, which could help doctors better monitor heart risks in people with lung disease.
AachenAges 18–99 - NCT05048862Recruiting
Brain scan and tests for neuromuscular conditions
This study compares people with neuromuscular disorders to healthy people using questionnaires and brain/neurological tests. It may help researchers understand how these conditions affect the brain and nervous system.

MRI study in adults with trigeminal neuralgia pain
This study uses a special MRI scan to look at how the trigeminal nerve system is working in people with essential trigeminal neuralgia (face pain) and whether there is nerve involvement. You may be asked to get MRI scans while resting, which can help doctors better understand the cause and guide future treatments.

Common questions
- Are there clinical trials for function?
- Yes. Clin2 currently lists 2,557 recruiting 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 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 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.
