Cerebral Palsy (CP) is a developmental disorder characterized by a group of movement and posture problems that occur as a result of a lesion in the immature brain and affect the development of the brain. Our study aimed to examine and compare the functional level, trunk control, and respiratory functions in children with cerebral palsy (CP). A total of 61 children with CP, 51% female, and 49% male, with a mean age of 11.21±3.02 years. Demographic and disease-related information were evaluated with ‘sociodemographic data form,’ functional levels with ‘Gross Motor Function Classification System, trunk control with ‘Trunk Control Measurement Scale’ (TCMS), and respiratory functions with ‘the respiratory function test’ using a spirometer. The functional levels of children with CP, 54% were Level 1, 26% were Level 2 and 20% were Level 3. In intergroup analysis, the mean trunk control of the children with Level 1 and 2 were statistically significantly higher than the children in Level 3 (p
