Boston, MassachusettsAges 18–80 - NCT05154253RecruitingPhase 1
Improving ankle push-off in children with cerebral palsy
This early (Phase 1) study tests a way to improve how well the ankle muscles help you push off when walking in cerebral palsy. If the ankle function improves, it may lead to a more comfortable and safer walking pattern.
Minneapolis, MinnesotaAges 8–21 - NCT05157282Recruiting
Spinal cord stimulation to improve hand function after tetraplegia
This trial tests whether a special device that stimulates the spinal cord can help people with long-lasting neck spinal cord injuries recover useful hand movement and grip strength. It may help your nervous system communicate better so daily hand tasks become easier.
Chicago, IllinoisAges 18–70 - NCT05165095Recruiting
Remote monitoring checks for new pacemakers
This trial tests how well remote monitoring features in certain pacemakers work after implantation. It may help your care team spot issues earlier and improve the remote alert system.
KremsAges 18 years+ - NCT05166954Recruiting
Bariatric surgery and heart function in people with high blood pressure
This study looks at whether bariatric (weight-loss) surgery improves heart function in people who have high blood pressure. You may be able to join if you’re already a bariatric surgery patient at the study hospital and meet the health and medication criteria.
Beijing, Beijing MunicipalityAges 17–70 - NCT05167786Recruiting
Electrical spinal cord stimulation for walking after stroke
This trial studies whether a non-surgical electrical treatment to the spinal area can improve walking and leg control after a stroke. It’s for people who have had a single stroke and still need hands-on support to walk.
Chicago, IllinoisAges 18 years+ - NCT05173740RecruitingPhase 4
Rehab program for people after an out-of-hospital cardiac arrest
This trial studies a rehabilitation program for adults who survived a first out-of-hospital cardiac arrest. It may help improve recovery after leaving the hospital by using guided follow-up and surveys to see how people are doing over time.
CopenhagenAges 18–65 - NCT05178914Recruiting
Testing heart pain treatment guided by blood-flow measurements
This study looks at how to personalize treatment for people with angina (chest pain) by measuring how well blood flows through the heart’s small vessels and the main arteries during a procedure. It may help doctors choose the right approach after your coronary angiography (heart artery imaging).
La TroncheAges 18 years+ - NCT05188079Recruiting
Test whether quick nitrate supplements change blood vessel function
This study checks how an acute (short-term) nitrate supplement affects how well your blood vessels work. It may help researchers understand whether these effects differ among Hispanic, Black, and White participants, in otherwise healthy adults.

EEG and brain stimulation study for depression reward symptoms
This study uses non-invasive brain stimulation (like TMS) and EEG brain recordings to measure how the brain’s “reward” system works in people with major depression. It may help researchers understand which stimulation approaches best affect depression-related reward processing.
San Francisco, CaliforniaAges 18–65 - NCT05212129Recruiting
Stimulation of the ear nerve to help gut symptoms
This study tests whether stimulating a nerve in the ear (called auricular vagal nerve stimulation) can improve upper gut symptoms in teens who may have hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobile spectrum disorder (HSD). It also checks whether this treatment helps nerves that control the body (autonomic nervous system) and how well the gut moves.
Milwaukee, WisconsinAges 10–18 - NCT05226247Recruiting
Check whether careful weaning prevents lung fluid buildup
This study looks at people on a breathing machine for more than 48 hours who are starting a “spontaneous breathing trial,” a test used to see if they can breathe on their own. It focuses on those at higher risk of “weaning-induced pulmonary edema,” meaning fluid can collect in the lungs during the weaning process.
DijonAges 18 years+ - NCT05228262Recruiting
Testing blood-vessel function and muscle strength in osteoporosis
This study looks at how well your blood vessels work and how strong your muscles are, in women after menopause with osteoporosis. You may be asked to start standard osteoporosis treatment, and the researchers will study pain and changes related to vascular function and sarcopenia (loss of muscle and strength).
