New device aims to help stroke survivors move their arms again
Symptom relief Recruiting nowThis pilot study tests whether a device called IVS3 is tolerable and easy to use for arm recovery in people who had a stroke at least 6 months ago. The device uses mirrored video to create the illusion that the affected arm is moving. Researchers will track how many sessions part…

New combo therapy aims to wake up the brain after stroke
Symptom relief Recruiting nowThis study tests whether adding a type of brain stimulation (called continuous theta burst stimulation) to mirror therapy can improve hemispatial neglect in people who have had a stroke. Neglect means the brain ignores one side of the world, often the left. Twenty-two stroke surv…
