The telerehabilitation group will participate in the treatment in their homes. While the participants are performing the activities in their own homes, applications will be made via webcam-based software (Zoom) and synchronous access via video and audio from the physiotherapist's computer screen. The activities determined by the physiotherapist will be directed to the family, and the activities will be adapted and implemented according to the child's needs and functional level.

Physiotherapy program will include the following applications:

• Tone regulation
• Active stretching and strengthening exercises
• Gross and fine motor activities to improve bilateral hand use
• Daily living activities to improve upper extremity functional skills such as dressing, eating, and buttoning.
• Arts and crafts activities

The face-to-face group will be treated in the clinic. To this group; The activities determined by the physiotherapist will be applied face to face.

Physiotherapy program will include the following applications:

• Tone regulation
• Active stretching and strengthening exercises
• Gross and fine motor activities to improve bilateral hand use
• Daily living activities to improve upper extremity functional skills such as dressing, eating, and buttoning.
• Arts and crafts activities

Telerehabilitation program: Intervention will be applied by video interview for 12 weeks, 2 days a week, 45 minutes a day through the Zoom application. The application is free and can be installed on desktop or laptop computers, tablets and smartphones. The content of the activities to be done for that session by phone call to the parent before the interventions; Information will be given about the preparations such as keeping the materials on the table, suitable environment for that week's session and camera angle. Instructions and tips for parent support during the intervention will be given before and during the session. Intervention will be focused on upper extremity skills and activities of daily life of the individuals.

It is used to evaluate the upper extremity motor functions of children. QUEST is a test that evaluates the quality of movement and dexterity of the child with SP. QUEST is concerned with how the child does the activity he or she can do. Examines the quality of upper limb skills in 7 sections. The highest score is 100, the lowest score is 50

This test was developed to evaluate the selective motor control of the upper extremity. It is a very practical and useful video-based assessment tool that can be applied in less than 15 minutes. No special equipment is required other than a video camera. It offers the opportunity to evaluate the selective movements of the shoulder, elbow, forearm, wrist and fingers for both right and left extremities. The person administering the test passively shows the participant the movements they are asked to do. Then the participant is asked to actively perform the movement shown. While performing the participant movements; Head, trunk and other extremity movements are taken with a video camera to provide the opportunity to observe. The degree of selective motor control is determined as 0-3 points for each joint, depending on the person's ability to perform movements and their shape.

t evaluates hand skills in children with CP according to the activity frames of ICF-CY. It consists of 21 items. The highest score is 20, the lowest score is 0.

Individuals' ROM degrees will be evaluated before and after the treatment using a electronic goniometer in the supine position. Individuals' shoulder flexion, abduction, internal and external rotation, elbow and wrist flexion and extension painless active ROM measurements will be evaluated and recorded.
