Virtual Reality (VR) and Functional Strength Training (FST) are methods being tested to help children with Cerebral Palsy (CP), a condition that affects movement. This study lasts 12 weeks, with children trying either VR or FST for the first 6 weeks. Each session is 60 minutes, three times a week. After 6 weeks, their progress is checked. If a child improves, they continue with the same method; if not, they might switch methods or combine both for the next 6 weeks. The goal is to find out which method helps improve arm function more effectively. At the end, researchers will talk to children and caregivers to learn about their experiences.

• Study length: 12 weeks, with sessions 3 times a week.
• Participants must be between 5-17 years old and meet certain health criteria.
• Children must not have had recent surgery or certain medical procedures.
