This study looks at a special exercise program, called GRASP, for people who have had a stroke. A stroke happens when blood flow to the brain is blocked or reduced, causing brain cells to die, which can affect movement and speech. The GRASP program is done at home and helps improve arm and hand movement. The study wants to find out if GRASP is better than regular therapy for improving arm function, daily activities, and quality of life. Participants are asked to do exercises at home for 4 to 6 weeks, attending sessions three times a week. Before starting, right after finishing, and three months later, doctors will check how well your arm and hand move. They'll also ask how you feel about the exercises. You can join if you are over 20, have had a first stroke affecting one arm, and can follow instructions. However, you cannot join if you have other arm problems or severe pain.

• Duration: 4 to 6 weeks of home exercises, 3 times a week
• Visits: Evaluations before, right after, and 3 months after
• Feedback: Interviews and surveys to share your thoughts
