Recruiting studies
- NCT05812339Enrolling by invitation
Mapping tests for stomach symptoms using body-surface sensors
This study checks whether a noninvasive “mapping” test placed on the belly and chest can help tell apart people with certain upper stomach symptoms from healthy controls. It may help researchers better understand stomach function and symptoms without relying only on invasive tests.
Calgary, AlbertaAges 18 years+ - NCT05682248Enrolling by invitation
Testing a brain assessment and stimulation system for unconsciousness
This trial studies a device and plan to assess brain function and deliver an intervention in people who are in a coma, minimally conscious state, or unresponsive arousal state after brain injury, stroke, or lack of oxygen. If you qualify, it may help doctors understand and potentially improve brain function over time.
BeijingAges 14–80 - NCT05632120Enrolling by invitation
Testing how COPD affects daily movement and participation
This study looks at how chronic obstructive pulmonary disease (COPD) may affect your body function, walking, and ability to take part in everyday life. It may help researchers understand what support or therapies could improve daily activities.
Istanbul, Fatih/İstanbulAges 35–80 - NCT05501028Enrolling by invitation
Audio-recorded gut symptom interview to help diagnose FGIDs
This trial uses natural-language conversations (spoken interactions) to improve how clinicians evaluate and diagnose functional gastrointestinal disorders, a group of conditions that affect the gut. If you are scheduled for a GI clinic visit or a diagnostic endoscopy, your recorded responses may help build better evaluation tools.
Boston, MassachusettsAges 18 years+ - NCT05500066Enrolling by invitation
Shoulder implant study for people needing shoulder replacement
This trial studies a specific shoulder replacement implant system. It may help people with damaged shoulder joints by testing how well the implant works and how it affects recovery and function.
Denver, ColoradoAges 18 years+ - NCT05435859Enrolling by invitation
Mapping the brain area for speech during surgery
This study uses tiny brain electrodes placed during surgery to better understand how a brain region helps with speech. The results may guide safer brain mapping during surgery for people with epilepsy or brain tumors.
San Francisco, CaliforniaAges 18–70 - NCT05339048Enrolling by invitation
Study of adults from Colombia’s Caribbean coast
This study follows adults who were born or are from Colombia’s Caribbean coast. The goal is to learn about health patterns in this community, but you would not be able to join if you meet certain medical or disability-related criteria.
Cartagena, Departamento de BolívarAges 18–80 - NCT05315596Enrolling by invitation
Tracking pain and recovery answers after surgery
This study checks how patients report pain and recovery over time after surgery. It may help improve how hospitals understand and manage pain after operations.
JenaAges 18 years+ - NCT05102981Enrolling by invitation
Compare emergency versus planned stoma recovery and quality of life
This trial studies how having a stoma made in an emergency versus as a planned procedure may affect your day-to-day life and recovery. It may help doctors better understand which approach leads to better quality of life.
GothenburgAges 18 years+ - NCT05038722Enrolling by invitation
Testing how platelet transfusions work in people with low platelets
This study looks at platelet transfusions—how they’re used and whether platelets function well—for people with blood cancers who have low platelet counts. It may help improve transfusion care for people who need platelet support.
LinköpingAges 18 years+ - NCT04875078Enrolling by invitation
UVA-1 light treatment for hand skin tightness in scleroderma
This study tests whether UVA-1 light sessions can loosen tight skin and improve hand function in people with scleroderma. If you qualify, you would attend UVA-1 treatments twice a week for the study period.
Murray, UtahAges 18 years+ - NCT04451044Enrolling by invitation
Guided heart stent planning using an inside pressure sensor
This study tests whether using a tiny pressure sensor in heart arteries during a procedure can better guide where to place a stent. It may help doctors choose the safest and most effective stent plan by more accurately measuring artery narrowing.
Birmingham, AlabamaAges 18 years+ - NCT04074356Enrolling by invitation
Tests for esophagus function using noninvasive body measurements
This study looks for noninvasive ways to measure how well your esophagus is moving. It may help doctors better evaluate swallowing and esophagus movement without relying only on invasive testing.
Nashville, TennesseeAges 18 years+ - NCT04043442Enrolling by invitationPhase 2
Brain stimulation study for alcohol use with mild brain injury
This trial tests a type of brain stimulation to help with day-to-day functioning in people who have alcohol use disorder and a history of mild traumatic brain injury. It also uses brain and symptom testing to see who may benefit most and why.
Hines, IllinoisAges 22–65 - NCT04042532Enrolling by invitation
Theta-burst brain stimulation for younger-onset Alzheimer’s
This trial tests whether a form of brain stimulation (theta-burst stimulation) can improve thinking and memory in people with younger-onset Alzheimer’s. It also compares results with people without dementia who meet similar age and health requirements.
Taoyuan, GuishanAges 50–75 - NCT03914664Enrolling by invitation
Brain and sensation study in adults with Tourette syndrome
This study looks at brain activity and how sensory experiences feel in adults with Tourette syndrome. It compares you to carefully matched adults without neurologic or psychiatric conditions to understand what is different in the brain.
Nashville, TennesseeAges 18 years+ - NCT03541135Enrolling by invitation
Study of heart health, diet, and activity in older adults
This study looks at heart health, food, and physical functioning in people age 65 and older living in Madrid. It may help researchers understand how lifestyle affects aging and cardiovascular wellbeing.
MadridAges 65–95 - NCT03407833Enrolling by invitation
Study changes in the body after weight, gut, or liver treatment
This study looks at how the body’s insulin-sensitivity (how well your body uses sugar/insulin) and organ function change after certain medical procedures. It may help researchers understand why some people improve after surgery or liver transplant and guide future care.
Nashville, TennesseeAges 18 years+ - NCT03369353Enrolling by invitation
Personalized immune testing study for bowel and transplant patients
This study looks at whether a precise lab test can help understand inflammatory bowel disease, functional gut disorders, and immune changes after stem cell transplant or cell therapy. It may help doctors choose better monitoring and treatments based on your immune and gut test results.
Boston, MassachusettsAges Any age - NCT03232463Enrolling by invitation
Testing an advanced MRI scan in everyday clinic care
This study checks whether a more advanced MRI scan can be safely used in regular clinical practice. If you need an MRI for a health problem, the study may help your care team use the newer scan approach.
Santa Monica, CaliforniaAges 18–65 - NCT03054792Enrolling by invitationPhase 1
MRI test to map low-oxygen areas in childhood sarcomas
This Phase 1 study uses special MRI scans to look at “low-oxygen” parts of a childhood sarcoma. It aims to help doctors better understand the tumor before standard treatment that may include chemotherapy and sometimes radiation.
Toronto, OntarioAges 6–18

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.
