Motor imagery training for arm strength after stroke
This trial tests if imagining arm movements (motor imagery training) can help improve arm strength in people who had a stroke at least 6 months ago. It is a non-drug, mental practice approach that may help your brain relearn movement.
IslamabadAges 45 years+ - NCT06945211Recruiting
Mirror therapy for arm movement after stroke
This study tests whether doing arm exercises while watching the reflection of your good arm in a mirror can help improve movement and function in your affected arm after a stroke.
IslamabadAges 45 years+ - NCT06946082Recruiting
Stroke study: arm and language skills in Turkish speakers
This study looks at how arm movement, body control, and mental imagery (imagining movement without actually doing it) relate to Turkish language abilities after a stroke. It aims to understand how these functions work together to help recovery.

Study of a stent-graft for aortic and iliac aneurysms
This trial is testing a specific stent-graft system, called E-liac, to treat aneurysms in the aorta or iliac arteries. It may be used alone or with other devices. The study will track how well it works.
Bari, BAAges Any age - NCT06946732Recruiting
Acostream for high-risk and intermediate-risk pulmonary embolism
This trial is testing a device (called the Acostream) to break up blood clots in the lungs for people with serious pulmonary embolism who cannot receive standard clot-busting drugs or surgery. It may be an option if you have high-risk or intermediate-risk PE and are between 18 and 85.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT06947135Recruiting
Testing painkiller injection for heart attack patients
This trial tests if injecting a painkiller near neck nerves can reduce heart damage after a heart attack. It is for patients with a specific type of heart attack who are scheduled for a procedure to open blocked arteries.
Hefei, AnhuiAges 18 years+ - NCT06947343Recruiting
Action observation vs motor relearning for stroke balance
This study compares two types of therapy—watching actions and a standard motor relearning program—to see which helps stroke survivors improve their balance and walking. If you are able to stand briefly, you may benefit from this extra rehab.
IslamabadAges 45 years+ - NCT06947707Recruiting
Blood thinners for brain blood clot in Chinese patients
This trial tests two blood thinner medicines, edoxaban and rivaroxaban, in Chinese patients with a blood clot in a brain vein (cerebral venous thrombosis). It aims to see if these medicines are safe and work well.
Beijing, Beijing MunicipalityAges 18–80 - NCT06947876Recruiting
PUFFINS brain health study for adults 50+
This study looks at how small blood vessel changes in the brain (called 'small vessel disease') affect thinking and memory over time. It may help us understand how to keep brains healthy as we age. If you are 50 or older and do not have any memory concerns, you might be able to join.

Boston, MassachusettsAges 18 years+ - NCT06949150Recruiting
Combined heart CT scan study for coronary artery disease
This study tests a new way to use CT scans to look at both the structure of your heart arteries and how well blood flows through them. It may help doctors get a more complete picture of coronary artery disease without extra procedures.
