What is already known on this subject Children with cerebral palsy (CP) often experience significant communication difficulties that restrict their participation in daily life. Previous research has documented the reliance of children with CP on nonverbal communication modes and the association between motor severity and communication outcomes, but systematic analyses using the structured framework of the Communication Matrix are scarce, particularly in Türkiye where AAC use is limited. What this paper adds to existing knowledge This study systematically examined communicative functions and behaviours in Turkish children with cerebral palsy using the Communication Matrix. The findings showed that obtaining and social interaction were the most frequently observed communicative functions, whereas refusal and providing information were less common. Symbolic communication, particularly abstract symbols and spoken language, was markedly limited, especially among children with severe motor impairments. These results highlight the close association between motor severity and communicative complexity, offering valuable evidence to inform both clinical practice and future research. What are the potential or actual clinical implications of this work? The findings underscore the urgent need to integrate augmentative and alternative communication (AAC) strategies into rehabilitation and educational services in Türkiye. The Communication Matrix is demonstrated as a practical tool for identifying individualized communication targets and monitoring progress, supporting more effective clinical decision-making and intervention planning.
