This study will evaluate whether a 5-day, 6-hours-per-day therapy camp called Camp Hand to Hands can help children with hemiplegic cerebral palsy improve their walking ability, stair climbing, and involvement in daily life. During the camp, children will wear a resting hand splint covered by a soft puppet glove on their stronger arm to encourage use of the more affected arm while participating in fun, play-based activities such as obstacle courses and crafts. The study team will conduct daily assessments of each child's walking endurance and stair navigation using the 6-Minute Walk Test (6MWT) and the Timed Up and Down Stairs (TuDS) test during the 5-day camp. Parents will also complete a brief questionnaire about their child's participation at home and in the community before and after the camp. The study seeks to determine whether this short CIMT program leads to improvements in mobility and daily function.
