Recruiting studies
- NCT06089031Recruiting
Belgian registry for coronary function testing
This study collects information from people having tests to check how well the blood vessels in the heart work. It helps doctors learn more about these tests and improve care for future patients.
Deurne, AntwerpAges 18 years+ - NCT06100601Recruiting
Nervous System and Voice Disorder Study
This study looks at how the autonomic nervous system (the part that controls things like heart rate and sweat) might be linked to functional dysphonia, a voice problem with no clear physical cause. If you have this voice disorder and meet the health and lifestyle criteria, your participation could help improve understanding of the condition.
Ghent, East-FlandersAges 18–60 - NCT05985668Recruiting
Better diagnosis for platelet function disorders
This study aims to improve how doctors diagnose platelet function disorders—problems with blood cells that help stop bleeding. If you have a known or suspected platelet disorder and are being seen at Karolinska University Hospital, this trial may offer better testing to find the cause of your bleeding issues.
StockholmAges 1 year+ - NCT07871708Recruiting
Beauty device for skin concerns
This study tests a handheld beauty device that may improve wrinkles, skin firmness, and skin texture. If you have signs of aging or skin texture issues, you might be eligible to try it at no cost.
Baltimore, MarylandAges 30–65 - NCT07865546Recruiting
Advanced brain scans for epilepsy surgery planning
This study uses a very powerful MRI scanner to get detailed images of the brain. It aims to help doctors better understand and plan surgery for people with epilepsy that doesn't improve with medication.
Pisa, ItalyAges 6–65 - NCT06215222Recruiting
Studying gut bacteria in IBS and digestive issues
This study uses a tiny capsule to collect samples from your small intestine to learn about gut bacteria in people with IBS or other functional gut disorders. It could help researchers understand what causes digestive symptoms.
Redwood City, CaliforniaAges 18–70 - NCT06232473RecruitingPhase 4
Education and duloxetine for multisystem functional somatic disorder
This trial tests whether a combination of patient education and the medication duloxetine can help people with a condition that causes multiple unexplained physical symptoms (functional somatic disorder). It aims to see if using both treatments together works better than either alone.
AarhusAges 18–60 - NCT07873424Recruiting
Recumbent cycling and electrical stimulation for leg rehab
This study tests whether combining recumbent cycling with electrical muscle stimulation can improve leg function. It may help people with leg weakness or injuries to recover strength and mobility.
Oro Verde, Entre Ríos ProvinceAges 18–60 - NCT05775588Recruiting
Lung valve treatment for severe COPD
This study tests tiny valves placed in your airways to see if they improve your heart and muscle function over the long term. It's for people with severe COPD (chronic lung disease) and significant emphysema damage.
Beijing, Beijing MunicipalityAges 18–90 - NCT05570552Recruiting
Testing health impacts in adults from smoky, arsenic-exposed homes
This study follows adults who took part in an earlier GEOHEALTH study and live in homes that use traditional stoves, with low-to-moderate arsenic exposure in drinking water. It aims to understand how these environmental factors affect health, and what changes might be possible.
DhakaAges 25–70 - NCT06129552Recruiting
Healthy nose cells study for sinusitis insight
This study is looking at healthy people to understand how certain cells in the nose work. It will compare them to people with sinus problems to learn what goes wrong in chronic sinusitis with nasal polyps.
LeuvenAges 18 years+ - NCT06334029Recruiting
Observing brain connections in epilepsy
This study is observing how the brain's connections and activity work in people with epilepsy. It uses MRI scans and EEG recordings to learn more about the condition, which may help improve future treatments.
Conegliano, TrevisoAges 6–65 - NCT05447273Recruiting
MRI to plan less invasive surgery for penile cancer
This trial studies how functional MRI scans (a special MRI that shows how tissues work) can help doctors plan surgery for newly diagnosed penile squamous cell cancer. It may help more people get organ-sparing surgery, which aims to remove the cancer while preserving as much function as possible.
OsloAges Any age - NCT06381726Recruiting
Personalized brain mapping to protect movement during glioma surgery
This study tests a personalized approach to map and protect the brain's movement pathways during surgery for slow-growing brain tumors. The goal is to remove as much tumor as possible while keeping your quality of life and movement abilities intact.
Milan, LombardyAges 18 years+ - NCT06317831Recruiting
Let's get functional: function in interstitial lung disease
This trial tests a program to help people with interstitial lung disease improve their daily function and activity. It is for Portuguese speakers with any type of ILD who are otherwise stable.
AveiroAges 18 years+ - NCT06398977Recruiting
Dapagliflozin to protect kidney function in dialysis patients
This trial tests whether a diabetes drug called dapagliflozin can help people on peritoneal dialysis keep their remaining kidney function longer. It is for patients who started dialysis recently and still make urine.
Chengdu, SichuanAges 18–75 - NCT07842952Recruiting
Understanding memory and thinking to improve mental health care for kids and teens
This study tests a new way of providing mental health care that considers how a child or teen thinks and remembers. It aims to see if using this approach helps young people get better care and feel better.
Ottawa, OntarioAges 7–17 - NCT07837076Recruiting
Blood vessel health in healthy women over 50
This study looks at how blood vessel walls work in healthy women over 50. It may help researchers understand normal aging and guide future heart health advice.
Clermont-FerrandAges 50 years+ - NCT07836621Recruiting
Kidney surgery for children with very low function in one kidney
This study tests a surgery to repair a blockage where the kidney meets the tube to the bladder. It is for children whose affected kidney works at less than 10% of its normal capacity, aiming to improve or preserve function.
Tanta, El-GharbiaAges 1 month–18 years - NCT07838324Recruiting
Pain reprocessing therapy for functional dyspepsia
This study tests a type of talk therapy called Pain Reprocessing Therapy (PRT) to see if it helps reduce stomach pain and discomfort in people with functional dyspepsia. The therapy aims to retrain the brain's response to pain signals, potentially easing symptoms.
Rochester, MinnesotaAges 18 years+ - NCT07841613Enrolling by invitation
How surgery timing affects blood clotting
This study looks at how the time of day (morning vs. evening) affects blood clotting during surgery for digestive tract tumors. It may help doctors better manage bleeding risks for patients like you.

Hormone treatment for overactive bladder and mood symptoms
This trial studies whether hormone treatment can improve overactive bladder symptoms, sexual well-being, mood (depressive symptoms), and body “autonomic” function (automatic body functions like heart rate and sweating) in post-menopausal women. It may help by targeting menopausal changes that can affect these symptoms.

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.
