Amsterdam, North HollandAges 18 years+ - NCT06543758RecruitingPhase 4
Gait rehab with a wearable robot at home
This trial tests whether using a wearable robotic device at home can improve walking ability in people who have had a stroke. If you have trouble walking due to a stroke, this study may help you regain strength and mobility.
Yongin-si, Gyeonggi-doAges 19–79 - NCT06692855Recruiting
Frailty score's role in predicting outcomes for cardiogenic shock
This study looks at whether a simple frailty score (measuring how well someone can function) can help predict recovery for people hospitalized with cardiogenic shock, a condition where the heart suddenly can't pump enough blood.
StrasbourgAges 18 years+ - NCT06692504Recruiting
Blood Thinner Side Effects in the Emergency Room
This study looks at side effects of blood thinners (anticoagulants) in patients who visited the emergency department. It helps doctors understand how to better manage these medications.
BesançonAges 18 years+ - NCT06692569Recruiting
Modified physical therapy for arm and hand recovery after stroke
This study tests a type of physical therapy called modified constraint-induced movement therapy to help improve arm and hand function in people who have had a stroke more than six months ago. You will be encouraged to use your affected arm more often while the stronger arm is gently restricted, which may help retrain your brain and improve movement.
Riyadh, Riyadh RegionAges 45–65 - NCT07635407Recruiting
Virtual Stent Planning to Improve Heart Artery Procedures
This trial tests whether using computer software to virtually plan stent placement before your heart procedure leads to better outcomes. The goal is to optimize how stents are positioned in your coronary arteries.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07630857Recruiting
Heart Mapping to Personalize Atrial Fibrillation Treatment
This trial tests a new way to map the heart's electrical signals to help doctors better target and treat atrial fibrillation (an irregular heartbeat). If you're having a procedure to treat AF, this study may help improve the success of your treatment.
Beijing, Beijing MunicipalityAges 18–80 - NCT07632586Recruiting
First-in-Human Heart Pump Implant Study
This trial tests a new tiny heart pump called the Icoms Flowmaker for patients with severe heart failure who cannot have a standard heart pump. The device may help your heart pump blood better and improve your ability to do daily activities.
PragueAges 18–80 - NCT07635784Recruiting
Hemorrhoid Treatment Registry: Tracking Embolization Safety
This registry collects information about a minimally invasive procedure called hemorrhoidal artery embolization (HAE), which blocks blood vessels feeding internal hemorrhoids. It's for adults with persistent bleeding hemorrhoids that haven't improved with standard treatments like creams or medications.
Libertyville, IllinoisAges 18 years+ - NCT07631078Recruiting
Transcranial magnetic stimulation plus therapy for arm recovery after stroke
This trial tests a new type of brain stimulation combined with physical therapy to help people who have had a stroke regain arm and hand movement. It's for individuals who have some movement but could still improve, at least a year after their stroke.
San Francisco, CaliforniaAges 18–80 - NCT07632001Recruiting
Miro3D Wound Matrix for Diabetic Foot Ulcers
This trial tests a new wound-healing product called Miro3D to help diabetic foot ulcers heal better. You would receive this product along with standard wound care to see if it helps your ulcer close faster than standard treatment alone.
Phoenix, ArizonaAges 18 years+ - NCT05746260Recruiting
Testing sleep timing to improve arm learning after stroke
This study looks at how sleep may affect how well people relearn arm movements after a stroke. If you’re within a month of a stroke that affected your arm, your participation could help researchers understand better ways to support recovery.
OxfordAges 18 years+ - NCT07637825Recruiting
Ultrasound brain stimulation for improving arm and leg movement after stroke
This study tests a painless, non-invasive ultrasound treatment that stimulates the brain to help improve arm and leg movement after a stroke. It aims to see if this treatment can help people recover more function.
Taizhou, JiangsuAges 18–75 - NCT07635758RecruitingPhase 1/Phase 2
Stem Cell Treatment for Recent Stroke Recovery
This trial tests whether special cells from human placenta can help your brain recover after a recent stroke. The treatment is given as an injection and aims to reduce long-term disability.
BeijingAges 18–80 - NCT07636642Recruiting
New Heart Attack Blood Test Accuracy Study
This study compares two versions of a sensitive heart attack blood test to see how well the newer version can quickly rule out heart attacks in the emergency department. You'll have blood drawn as part of your normal care, and researchers will review your medical records.
Edinburgh, MidlothianAges 18 years+ - NCT07629635RecruitingPhase 3
