Preventing blood clots in hypertrophic cardiomyopathy with rivaroxaban
This trial tests if the blood thinner rivaroxaban can prevent strokes in people with hypertrophic cardiomyopathy who have early signs of damage in their left atrium (the heart's upper chamber). You may qualify if you have this condition, are in a normal heart rhythm, and are between 40 and 80 years old.
AngersAges 40–80 - NCT07203222Recruiting
Laser vs electric stimulation for shoulder pain after stroke
This study compares two non-invasive treatments—low-level laser therapy and electrical nerve stimulation—to see which works better for relieving moderate to severe shoulder pain in people who have had a stroke. If you have had a stroke in the last 2 weeks to 6 months and have shoulder pain, this trial may be an option for you.
Ankara, YenimahalleAges 18–75 - NCT07203625RecruitingPhase 4
Tenecteplase before transfer for basilar artery stroke
This trial tests if a clot-busting drug called Tenecteplase helps people with a severe type of stroke in the back of the brain (basilar artery occlusion) when given 4.5 to 24 hours after symptoms start. Patients will then be moved to a hospital that can remove the clot. The goal is to see if the drug improves recovery.
BeijingAges 18 years+ - NCT07204067Recruiting
Mirror therapy for hand recovery after recent stroke
This study tests whether mirror therapy—a simple exercise where you watch your unaffected hand move in a mirror to trick your brain—can help improve hand function after a recent stroke. It is for people who have had a stroke within the last month and have weakness on one side of their body.
