Home-Based Training With Feedback to Improve Outcomes in Adolescents and Young Adults With Cerebral Palsy..

This clinical trial aims to determine whether extrinsic feedback through music enhances the effects of home-based motor training for adolescents and young adults with cerebral palsy (CP) and whether feedback improves adherence to the training program. The main questions it aims to answer are: * Does extrinsic feedback improve real-world movement more than home training alone? * Do participants receiving extrinsic feedback adhere more closely to their training program? To determine its effectiveness, the investigators will compare home-based training with and without real-time music feedback. Participants will: * Engage in a home-based motor training program for 12 weeks, tailored to their individual needs and goals. * Receive real-time music feedback during training or no feedback (control group). * Attend weekly virtual coaching sessions to discuss short-term goals and training progress. * Undergo movement assessments before training, at 12 weeks (T2) and 24 weeks (T3). * Wear movement sensors for 72 hours at T2 and T3 to track real-world movement behavior.
