This study aims to compare the effects of neurodevelopmental techniques (NDT) and functional electrical stimulation (FES) on upper extremity function in children with hemiplegic cerebral palsy. 30 children between ages 4-8 will be randomly divided into two groups. The experimental group will receive NDT treatment, while the control group will receive conventional therapy with FES. Both groups will receive treatment 5 days a week for 4 weeks. Outcome measures including the Modified Tardieu Scale, Manual Ability Classification System, and Quality of Upper Extremity Skills Test will be used to assess upper extremity function pre- and post-treatment. The researchers hypothesize that NDT will significantly improve upper extremity function more than
