Visual feedback training to help walking after stroke
This study uses a special brain-scanning technique to guide video feedback training for people who have had a stroke, aiming to improve walking ability. It is for those who can move their legs a little and understand instructions.
Shenyang, LiaoningAges 18–75 - NCT07016295Recruiting
Monitoring Arm Recovery After Stroke (MARS)
This study tracks how well your arm recovers after a stroke. You'll be monitored as you go through your usual rehab, and the goal is to better understand arm recovery patterns.
LondonAges 18 years+ - NCT07016477Recruiting
Heart CT study for TAVI planning
This study is a registry (a collection of information) for people who are about to have a TAVI heart valve procedure. It will see how a new type of CT scanner (the NAEOTOM Alpha) can help doctors plan the procedure better.
Charleston, South CarolinaAges 18 years+ - NCT07016698Recruiting
Real-world registry study of the Rotarex device for clearing leg blockages
This study collects information on people who are treated with a device called Rotarex that uses a spinning tool to remove plaque from blocked leg arteries. It aims to understand how well the device works in real-world use to help patients with reduced blood flow to their legs.
Lakeland, FloridaAges 22 years+ - NCT07016854Recruiting
Early treatment for blocked carotid artery stroke
This trial tests whether early treatment (using a catheter to open the blocked artery) can help people with a stroke caused by a blockage in the internal carotid artery. The goal is to improve recovery and reduce disability.
Hangzhou, ZhejiangAges 18 years+ - NCT07018050RecruitingPhase 2
A study of a new combination for multiple myeloma
This study tests a new combination therapy for people with multiple myeloma that has returned or not responded to at least one prior treatment. The goal is to see if the combination (QLS32015 plus other drugs) can effectively control the cancer.
TianjinAges 18 years+ - NCT07018336Recruiting
Mirror therapy vs virtual reality for arm recovery after stroke
This study compares two therapies—mirror therapy and virtual reality—to help improve arm and hand function in people who have had a stroke. It aims to find which approach works better for recovery.
Istanbul, GaziosmanpaşaAges 18–75 - NCT07018596Recruiting
New pulsed field ablation for paroxysmal atrial fibrillation
This trial tests a new type of heart procedure that uses gentle electrical pulses to fix abnormal signals in the upper chambers of the heart for people with a specific type of atrial fibrillation that comes and goes on its own. It may be an option if your AFib episodes stop within 7 days and medications haven't helped enough.
Prague, RoentgenovaAges 18–85 - NCT07018557RecruitingPhase 4
Eszopiclone for sleep and blood pressure in insomnia with high blood pressure
This trial tests if a sleep medication (eszopiclone) can lower blood pressure in people who have both insomnia and high blood pressure. You may qualify if you have trouble sleeping and your blood pressure is not well controlled despite treatment.
