Study of autoimmune changes in postural tachycardia syndrome
This trial studies whether an autoimmune (immune system–related) process is involved in postural tachycardia syndrome (POTS), a condition where your heart rate rises when you stand. The study may help researchers understand what causes POTS and how it could be treated or monitored.
Oklahoma City, OklahomaAges 18–50 - NCT02236143Enrolling by invitation
Body MRI scan study using an ultra-high-resolution scanner
This study tests how well an ultra-powerful MRI machine can take detailed pictures of the body. You would get MRI scans to help researchers improve imaging, and you must be safe for MRI (no certain metal or implants).
Minneapolis, MinnesotaAges 18–75 - NCT02610855Enrolling by invitation
Study of activity and muscle function in children with scoliosis
This study looks at how children’s activity levels and muscle performance change in different scoliosis treatments (surgery, bracing, or healthy peers). It uses motion sensors and an ultrasound-based test to better understand what treatments may do to the body’s muscles.
Rochester, MinnesotaAges 9–16 - NCT01654133Enrolling by invitation
Testing branched stent grafts’ effect on blood flow after aortic repair
This study evaluates how well branched stent grafts work after repairing certain large or fast-growing aortic aneurysms (bulges in the main artery). It also checks blood-flow and organ function—especially flow to organs—in the weeks and months after the procedure.
Chapel Hill, North CarolinaAges 18 years+ - NCT00833599Enrolling by invitation
Scan lymph drainage and collect samples for related conditions
This study uses a special light scan after a dye is given to look at how your lymph system drains. It may also include genetic testing for people with a family history of lymph-related disorders to better understand causes.
Houston, TexasAges 3 months+ - NCT02023060Recruiting
Improving function and quality of life after heart valve repair
This study looks at how a less invasive heart valve procedure affects your day-to-day functioning and overall quality of life. If you’re already being considered for a transcatheter (catheter-based) valve replacement, you may be able to join to help understand what improvements patients experience.
JerusalemAges 18–110 - NCT01654159Enrolling by invitation
Study of vision and lens optics during cataract surgery
This study looks at how well your vision works and how different cataract surgery lens choices perform. It may help researchers better understand what affects sight after cataract surgery.
Birmingham, West MidlandsAges 40–85 - NCT00001159Recruiting
Studying how thyroid problems develop over time
This is an observational study that follows people with known or suspected thyroid problems to better understand how these conditions develop and behave. It doesn't test a new treatment, but it helps doctors learn more about thyroid disorders, which may improve care.
Bethesda, MarylandAges 6 months–98 years - NCT07400367Recruiting
Probiotics and lifestyle changes for fatty liver disease
This trial tests whether taking probiotics plus making lifestyle changes can improve fatty liver and metabolic health. You may qualify if you have liver fat and at least one sign of metabolic problems like high blood sugar or high blood pressure.
New Taipei CityAges 18–80 - NCT07400692Recruiting
Surgery vs. Non-surgery for Broken Elbow in Older Adults
This study compares two ways to treat a certain type of broken elbow in adults over 65 who are not extremely active or frail. It tests if using a metal plate to fix the bone during surgery leads to better arm function and recovery than treating the injury without surgery.
LuganoAges 65 years+ - NCT07402200Recruiting
Indoor air pollutants and child health study
This study looks at how indoor air pollution affects children's health. It compares children with allergies or asthma to those without, to see if air quality plays a role.
MontpellierAges 8–12 - NCT07402655Recruiting
Study on nerve injuries in the arm and their long-term effects
This study looks at people who have had a recent nerve injury in their arm, hand, or wrist that needed treatment. It aims to understand how the injury affects movement, feeling, and quality of life over time.
IspartaAges 18–80 - NCT07403331Recruiting
Nerve pain in legs: spinal cord stimulation plus team care
This trial tests a treatment bundle that combines a spinal cord stimulator (a device that sends mild electrical pulses to your spine to block pain signals) with a team of specialists (like a psychologist and physical therapist) to reduce chronic nerve pain in the legs and improve your ability to move and function.
OsloAges 18–60 - NCT07404761Recruiting
Moving your arm after stroke or TBI
This study tests a device that uses mild electrical pulses and augmented reality (a computer overlay on real life) to help people who have arm or hand weakness after a recent stroke or brain injury regain movement.
HaifaAges 18 years+ - NCT07405021Recruiting
Vagus nerve stimulation for diabetic nerve pain
This trial tests whether using a non-invasive device to stimulate the vagus nerve can reduce nerve pain and improve function in people with diabetic neuropathy. It may be a good option if you have burning or electric-shock-like foot pain despite standard diabetes care.
DamiettaAges 45–60 - NCT07405333Recruiting
Coughing exercises vs breathing device after heart surgery in children

Common questions
- Are there clinical trials for functionality?
- Yes. Clin2 currently lists 2,565 recruiting functionality 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 functionality 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 functionality 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.
