The aim of this study is to examine the relationship between trunk control and lower extremity selective motor control and balance problems during the movement of sit to stand (STS) frequently encountered in children with cerebral palsy (CP) in daily life and to compare the STS performance of in children with CP and typical developing children. CP patients have difficulty in daily life activities due to muscle weakness, lack of muscle coordination, balance and postural control disorders. STS activity, which is one of the most frequently used activities in daily life, is a biomechanical activity in children with CP, requiring neuromuscular coordination and postural control outside of muscle strength. It is not enough to evaluate the muscle strength to evaluate the STS movement which is very important for these group, it is necessary to evaluate the balance of this movement of children with CP and the isolated muscle strengths (selective motor controls) of the lower extremity that we believe may affect this movement. There is not enough information about whether there is a relationship between the trunk controls and the selective motor controls of the lower extremities during the STS movement in children with CP. The information in the literature is limited to the fact that trunk control and muscle strength affect the balance during the STS movement. However, there is no study examining the relationship between selective motor control and trunk control during STS movement in children with CP.~This study, which includes selective motor control and trunk control, aims to eliminate this deficiency in the literature. In addition, the performance of the participants STS movement will be evaluated objectively with the test of the computerized balance device planned to be applied. In this study, to in children with CP; Modified Ashworth Scale to evaluate spasticity in the hip, knee and ankle, Gross Motor Function Classification System to determine gross motor levels, Trunk Control Measurement Scale to measure dynamic and static balance, Gross Motor Function Measure-88's sitting sub-test to assess seating function, Selective Control Assesment of Lower Extremity to assess the selective motor control of the knee and ankle muscles, the sit to stand test of the computerized postural analysis device will be applied to assess the duration of the STS movement and the deviations during the movement. The application time of the tests varies between 5-30 minutes.~For typical developing children, all tests except the Modified Ashworth Scale and the Gross Motor Function Classification System will be applied from tests applied to children with CP.~This study will evaluate the independence of children with CP in daily life activities and contribute to the correct planning of rehabilitation goals.
