Restore leg sensation in diabetic nerve damage with safe stimulation
This study tests a treatment that delivers mild stimulation to help bring back lower-limb feeling in people with diabetic nerve damage (or an insensate foot) and may also protect nerves. If you qualify and can safely take part in testing and follow-up, it could improve sensation and walking comfort.

Refining communication training for kids with behavior challenges
This study tests an improved version of functional communication training for children ages 3 to 17 whose destructive behavior (like hitting or yelling) happens often and is fueled by social attention. It aims to help children learn better ways to get attention instead of using hard-to-manage behaviors.
Somerset, New JerseyAges 3–17 - NCT04628429Recruiting
Study CGRP blocker effects on migraine and body nerve function
This study tests a CGRP-blocking antibody to see how it affects migraine symptoms and the body’s automatic (involuntary) nerve functions. It may help people with migraine who have already tried several preventive medicines.
ViennaAges 18–64 - NCT04474106Recruiting
Shock wave therapy for new spinal cord injuries
This study tests whether extracorporeal shock wave therapy (non-surgical shock waves delivered from outside the body) can improve movement and sensation after a recent spinal cord injury. It may help people recover motor (movement) and sensory (feeling) function within months after injury.
Innsbruck, TyrolAges 18–99 - NCT04246138Recruiting
Robot-assisted knee replacement alignment: best function
This trial compares two types of robot-guided knee replacement alignment to see which one helps people do everyday activities better after surgery. If you have “wear-and-tear” knee arthritis, you may be offered one of the two surgical alignment approaches as part of a study.
Hull, East YorkshireAges 18–90 - NCT04458584Recruiting
Thumb surgery trial comparing treatments for basal joint arthritis
This study looks at how well different thumb (basal joint) surgery approaches restore strength and function. You would be having planned (non-replacement) thumb surgery, and your chosen surgeon would care for you while researchers compare outcomes.
Lebanon, New HampshireAges 21 years+ - NCT02924818Recruiting
Research study for adults with long-term breathing lung diseases
This study enrolls adults with chronic lung conditions like COPD, cystic fibrosis, bronchiectasis, or interstitial lung disease. It’s designed to learn more about these illnesses and to develop better ways to study or improve care.
ReimsAges 18 years+ - NCT05593627RecruitingPhase 4
Lithium to improve sleep and thinking after heart surgery
This trial tests whether lithium carbonate can improve sleep and thinking (cognitive function) after heart valve surgery that uses a heart-lung machine. It may help some people who have trouble sleeping or thinking after surgery, but it excludes people with significant sleep or thinking problems before surgery.
Shenyang, LiaoningAges 18–65 - NCT03137095Recruiting
Study how chemotherapy affects brain function in breast cancer
This study looks at changes in thinking and brain function in people with early to locally advanced breast cancer before and during chemotherapy. You may also be offered a brain MRI in a separate optional part of the research to learn more about brain changes.
Rochester, New YorkAges 21 years+ - NCT02382601Recruiting
Study of pregnancies with slow fetal growth
This study follows pregnancies where the baby appears smaller than expected on ultrasound. It may help researchers better understand why this happens and how to monitor care over time.
Aurora, ColoradoAges 18–45 - NCT07667985Recruiting
Cognitive Reserve and Recovery from Fatigue in Older Adults
This study looks at how life experiences and education (cognitive reserve) help older adults bounce back from mental fatigue. Researchers want to find out if higher cognitive reserve leads to faster recovery after tiredness, which could improve quality of life.
Uşak, UşakAges 65–90 - NCT02855827Recruiting
Monitoring patients who may receive ovarian tissue back
This study follows people who have saved their own ovarian tissue (cryopreserved tissue) and may receive it back to try to restore ovarian function. It’s mainly for people with premature ovarian insufficiency and plans for tissue autograft, with monitoring for safety and outcomes.
BesançonAges 11–43 - NCT03763864Enrolling by invitation
Testing patient skin cells to check gene-related disease causes
This trial builds lab tests using a patient’s own skin cells to see whether the disease’s underlying gene problem can be shown in the lab. If you have a rare inherited (genetic) disease with no good treatment, this could help researchers find clearer, functional ways to measure the disease and test future therapies.
LilleAges Any age - NCT07108920Recruiting
Balance and Botox for Stiff Knee Gait
This study tests whether botulinum toxin (Botox) injections into the rectus femoris thigh muscle can improve balance and walking in people with a stiff knee gait (a common problem after stroke, brain injury, or multiple sclerosis).
Héricourt, Nord Franche-ComtéAges 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 - NCT07143773RecruitingPhase 4
SGLT2i safety in kidney transplant patients without diabetes
This study tests whether a medicine called SGLT2i (a type of pill for kidney health) is safe and helpful for kidney transplant recipients who do not have diabetes. It aims to see if it can improve how the new kidney works.
OdenseAges 18 years+ - NCT02825654Enrolling by invitation
Deployed Veterans Study of Service and Health
This study looks at how military service and deployment experiences relate to health and wellbeing in veterans who served after 9/11. It may help researchers understand which factors affect long-term health.
San Diego, CaliforniaAges Any age - NCT03286686Recruiting
Study of thinking and hand skills after brain injury
This study looks at how people with an injury to the back part of the brain (posterior parietal cortex) process what they see and guide their movements. It may help researchers better understand the symptoms and improve future therapies.
BronAges 18–75 - NCT06210555Recruiting
MRI Study of Kidney Donors, Recipients, and Healthy People
This study uses advanced MRI scans to look at kidney health in living donors, transplant recipients, and healthy people. It aims to find links between MRI results and kidney function, fibrosis (scarring), and aging.
Aarhus, Central JutlandAges 18–80 - NCT02321007Recruiting
Study placenta function in healthy and pregnancy complications
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 - NCT05289245Recruiting
Registry study for Chinese people with cystic fibrosis
This study keeps a national record of people diagnosed with cystic fibrosis (CF) in China. It aims to better understand CF over time and may help future care by improving how patients are tracked and studied.
Beijing, Beijing MunicipalityAges Any age - NCT06202443Recruiting
Physical therapy timing after neck surgery
This study looks at whether starting physical therapy soon after ACDF neck surgery helps people recover better. It compares early physical therapy to standard care.

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.
