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 - 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 - NCT02290834Recruiting
Studying brain and thinking changes after chemotherapy in older breast cancer patients
This study looks at how chemotherapy may affect memory and thinking, using thinking tests and possibly brain imaging. It compares older breast cancer patients who do and do not get chemotherapy, plus a group of healthy older adults.
Boston, MassachusettsAges 60 years+ - NCT02321007Recruiting

This study examines how the placenta works in normal pregnancies and in pregnancies with certain complications. Your answers and pregnancy information may help researchers understand why complications like growth problems or preterm birth happen.
Aurora, ColoradoAges 18–45 - NCT02543424Recruiting
Testing movement and thinking in brain-injury and cerebral palsy
This study looks at how people’s arm/hand movement and attention-thinking skills work after brain injury or cerebral palsy. You might be invited to tasks and simple instructions to help researchers understand function and possible support strategies.
Ottignies, Brabant WallonAges 5 years+ - NCT02331979Recruiting
Neuromodulation trial to improve bladder function after spinal injury
This trial tests a nerve-stimulation approach to improve bladder control in people with spinal cord injury. It specifically targets bladder problems that require clean intermittent catheter use and includes regular testing over 6 months.

Cryopreserved cord blood access program for transplant patients
This trial studies an organized way to obtain and distribute unlicensed (not FDA-approved for general use) stored cord blood units that have been frozen and kept. It may help people who need a cord blood transplant but don’t fit the “licensed cord blood only” options.
Birmingham, AlabamaAges Any age - 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 - NCT01630421Recruiting
Study genes behind aplasia cutis congenita (ACC)
This study looks at the genes and body effects behind aplasia cutis congenita (ACC). It is mainly for people who have ACC, and it may include unaffected family members only if they are part of a research family group.
Farmington, ConnecticutAges Any age - NCT01630460Recruiting
Study of genetics in craniometaphyseal dysplasia (CMD)
This study looks at the genes and related body functions in people with craniometaphyseal dysplasia (CMD). It may help researchers understand the condition better, especially by comparing affected family members to those who are not affected.
Farmington, ConnecticutAges Any age - NCT01630447Recruiting
Study of cherubism genes and how the condition works
This study looks at the genes in people with cherubism to understand how the condition develops. If you have cherubism—or are part of a family where cherubism is being studied—you may be invited to take part.
Farmington, ConnecticutAges Any age - 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+ - NCT01957267Recruiting
Eye imaging study for glaucoma detection
This study uses advanced eye scans to compare the eyes of people with glaucoma against those with healthy eyes. It aims to find better ways to detect and monitor glaucoma, which could help preserve vision.
Portland, OregonAges 40–85 - NCT01581424Recruiting
Study how kidney findings change in Fabry disease
This study looks at the natural course of Fabry disease in the kidneys and how different kidney test results relate to each other. It may help doctors better understand kidney progression and treatment outcomes, including for people who have or have not had enzyme replacement therapy.
Minneapolis, MinnesotaAges 1–75 - NCT02098265Recruiting
Brain-signal device for stroke arm rehabilitation
This study tests a device that uses brain activity signals to trigger stroke arm therapy. It may help improve how well your upper arm and hand function by timing the training to your brain’s patterns.
Madison, WisconsinAges 18 years+ - NCT01822470Enrolling by invitation
Registry studying bacteria patterns in suspected small bowel overgrowth
This is a research registry that collects small-bowel fluid samples from people being tested for “SIBO” (an overgrowth of bacteria in the small intestine). It aims to describe what bacteria are present and how results differ between people with suspected SIBO and others having similar tests for other reasons.
Indianapolis, IndianaAges 18–90 - NCT01999374Recruiting
Long-term follow-up for people with transplanted islet cells
This study checks how well transplanted islet cells are working over time and monitors long-term safety. If you previously received an islet transplant and are still using medicine to prevent rejection, you may be followed again.
Miami, FloridaAges 18–65 - 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+ - NCT01036581Recruiting
Brain MRI study to improve brain imaging for drug research
This study uses advanced MRI brain scans to better show how the brain responds to medicines (drug-related effects). You may also do extra safety screening and non-invasive brain stimulation for some parts of the research.
Baltimore, MarylandAges 18–80 - NCT00001159Recruiting
Thyroid disorder natural history study
This study observes people with various thyroid conditions, including overactive or underactive thyroid, to learn more about how these disorders develop and progress over time. It may help improve future diagnosis and treatment.
Bethesda, MarylandAges 6 months–98 years - NCT00051857Recruiting
MRI Study of Muscle and Bone Function
This research study uses MRI scans (a safe imaging tool) to understand how bones, muscles, and joints work. Researchers are looking for both people with muscle or bone injuries and healthy volunteers to compare how the body moves and functions.

Understanding eosinophil behavior in rare blood and tissue conditions
This research study examines how eosinophils (a type of white blood cell) behave and function when they become abnormally high in the blood or tissues. Researchers want to understand these conditions better to potentially improve treatment options.

Common questions
- Are there clinical trials for functionality?
- Yes. Clin2 currently lists 2,474 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.
