Study brain changes after deep brain stimulation for tremor
This study looks at how brain “wiring” (connectivity) and brain function change over time in people with essential tremor after successful deep brain stimulation. You might benefit by helping researchers better understand what DBS does in the brain, which can improve care for others with tremor.

Testing a brain-controlled hand device after a stroke
This study tests whether a “closed-loop” neuroprosthesis (a hand-control device that responds to your movement) can improve hand grasping after a stroke. It may help people who cannot open or grab objects on their own, and who can safely participate during a short hospital stay.
ToulouseAges 18 years+ - NCT04812314Recruiting
Study how exercise changes body fat and metabolism
This study looks at how starting exercise changes the structure and function of body fat. It may help you understand how exercise affects things like cholesterol and blood sugar, even if you’re not currently exercising regularly.
Ann Arbor, MichiganAges 18–40 - NCT04814082Recruiting
Compare two knee implant types for walking and function
This study compares two designs of knee replacement implants to see how they affect walking, function, and outcomes after surgery. You may be randomly assigned to one of the implant types used for your specific, approved knee replacement.
Baltimore, MarylandAges 18–75 - NCT04831957Recruiting
Testing thyroid hormone changes after TAVI in older adults
This study looks at how thyroid problems may develop after a heart procedure called TAVI in people age 70 and older. It may help doctors spot thyroid side effects earlier so they can treat them sooner.
BrusselsAges 70 years+ - NCT04833426RecruitingPhase 3
Testosterone levels around prostate surgery and recovery outcomes
This trial studies whether testosterone levels before and around radical prostate surgery affect cancer control and sexual/physical recovery. It may help doctors understand who benefits from testosterone replacement and who should not.
AmsterdamAges 18 years+ - NCT04858347Recruiting
Study of a specific knee implant and recovery outcomes
This trial looks at how well a particular knee replacement (a GEMINI SL fixed-bearing prosthesis) works and how people function after surgery. It may help doctors learn what to expect for recovery and long-term results with this implant.
Cali, Valle del Cauca DepartmentAges 18–80 - NCT04859335Recruiting
Tracking balance and inner-ear function after Gamma Knife for schwannoma
This study looks at how balance and inner-ear (vestibular) function change after Gamma Knife radiosurgery for vestibular schwannoma. It may help doctors understand what to expect during recovery and how well these functions improve.
ToulouseAges 18–65 - NCT04861194Recruiting
Test treatment plans to preserve erections during prostate radiation
This trial studies ways to help preserve erectile function while you receive radiation treatment for prostate cancer. It may help by aiming to protect erections, especially for people at low to intermediate risk.
Utrecht, UtrechtAges 18 years+ - NCT04879862Recruiting
Study of walking and bladder recovery after recent spinal injury
This study looks at how leg movement and bladder function change after an acute spinal cord injury. It’s meant for adults who recently injured their spine and cannot stand or move their leg joints on their own.
West Orange, New JerseyAges 18–65 - NCT04883463Recruiting
Brain and spinal stimulation to improve breathing after SCI
This trial tests a neuromodulation treatment to improve breathing in people living with a cervical spinal cord injury who have significant breathing problems. If you qualify, you would have regular weekly testing over many months to see whether breathing and breathing support needs improve.
Los Angeles, CaliforniaAges 18–75 - NCT04883502Recruiting
Testing a technique to rebuild bone lost after injury

ClamartAges 18 years+ - NCT04898790Recruiting
Testing ways to improve thinking after bone marrow transplant
This study looks at whether a physical activity program and related study measures can improve thinking and memory in older adults around the time of a stem cell transplant. If you qualify and participate, the team will compare outcomes between groups to see what approach works best.
Omaha, NebraskaAges 19 years+ - NCT04917471Recruiting
Testing nitrate to improve red blood cell function in type 2 diabetes

StockholmAges 18 years+ - NCT04919980Recruiting
Testing a new mitral valve repair device for high-surgery-risk patients

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.
