Inclusion Criterias: Being diagnosed with Cerebral Palsy. Volunteer. Be between the ages of 6-18. Being at level 1 and level 2 according to Gross Motor Function Classification System (GMFCS) (Level 1 and 2).

To have the cognitive skills to understand and apply the evaluation parameters.

Exclusion Criterias: Cognitive impairment of participants diagnosed with Cerebral Palsy. Participants diagnosed with Cerebral Palsy have vision or hearing problems. Participants diagnosed with Cerebral Palsy must have a history of trauma such as botox or muscle relaxation operation and/or fracture at least 6 months before participating in the study.

Within the scope of the study, the participants will be evaluated for 30 minutes in a single session. The participants' trunk stabilization and endurance, balance, functional mobility, upper extremity endurance, functional health and quality of life will be questioned by questionnaires, scales and tests. Evaluation will begin with a literature-supported demographic data form prepared for the participants.

Assessments to be made are listed below. Trunk Control Measurement Scale (TCMS) Pediatric Balance Scale (PBS) Time Up and Go test (TUG) Trunk Flexor Test (TFT) The Pediatric Outcomes Data Collection Instrument (PODCI)

TCMS consists of static sitting balance, dynamic sitting control (Selective motor control and dynamic reaching) sections. The scale consists of 15 items in total and is divided into five, seven and three items. All items are evaluated bilaterally and scored on a 2, 3 or 4 point rank scale. TCMS total score is between 0-58 and the higher the score, the better the performance. Participants' trunk stabilization will be evaluated with TCMS.

The five-level consists of 14 elements such as sitting balance, standing balance, standing up from sitting, moving from standing to sitting, transfers, stepping, reaching, turning and jumping. Each item is scored between 0-4 points. High scores indicate better performance. Participants' balance will be evaluated with PBS.

The participant sitting on the floor without arm support, hip and knee flexed at 90 degrees and feet on the ground are asked to stand up, walk 3 meters, turn around and sit on the chair. The test is applied 3 times, the time is recorded and the average of 3 trials is taken. Participants' functional mobility will be evaluated with TUG.

In the test performed to evaluate trunk endurance, the starting position is trunk flexed to 60 degrees (supported by a foam wedge), hips and knees flexed to 90 degrees, and feet in a stable position. In the test position, after the wedge is lifted, the participant is asked to try to keep the body in the flexion position at 60 degrees as much as possible and the time is recorded in seconds. The trunk endurance of the participants will be evaluated with the Trunk Flexor Test.

In the test used to evaluate the endurance of the upper extremities, in the starting position, individuals are asked to lie in a prone position, take their hands at shoulder level, flex their elbows to the side of the trunk, and bring their knees to 90 degrees of flexion. Then, while in this position, they are asked to raise the head, shoulders and trunk for 30 seconds, with the elbows in full extension. The number of repetitions of the movement for 30 seconds is recorded. Participants' upper extremity endurance will be evaluated with the Modified Push-up Test.
