The study is about improving recovery after a stroke, which happens when blood flow to the brain is blocked or a blood vessel bursts. This affects the brain and can cause problems with moving arms and hands. The study looks at biomarkers, which are signs in the body that tell us how well someone might recover. These are checked using Transmagnetic Stimulation (TMS), a test that uses magnetic fields, and MRI, which is a scan that shows pictures of the inside of the body.

• The study lasts for 90 days and involves checking arm and hand movement after a stroke.
• It will take place at up to 35 sites and needs 657 participants.
• People must be 18 or older, have had a stroke, and be able to move their shoulder and fingers a little.

Participants should not have arm injuries before the stroke, should not be legally blind, and must be able to understand the study procedures. They cannot join if they have certain health issues, are pregnant, or cannot undergo TMS or MRI. The goal is to help understand who might need more help and improve stroke recovery methods.
