Objective To systematically analyze the characteristics of impairment of speech function and activity limitation of com-munication in children with intellectual disabilities,and to develop comprehensive rehabilitation interventions.Methods An in-depth analysis of impairments of speech functions and activity limitation of communication in children with intellectual disabilities across multiple dimensions was conducted using International Classification of Func-tioning,Disability and Health(ICF)framework,from the aspects of body structures and functions,activities and participation,and environmental factors.Integrated intervention methods were implemented within speech reha-bilitation and special education settings.Results Speech function impairments often manifested as deficits in the mental functions of language,articulation func-tions,and the fluency and rhythm of speech.Communication limitations were evident,including potential defi-cits or difficulties in speaking,listening,engaging in conversations and interpersonal interactions.Environmental factors such as family support,peer attitudes,professional services and the accessibility of assistive communica-tion technologies significantly impacted the development of speech function and communication activity in these children.This study proposed a systematic assessment methodology for children's speech function and communi-cation activity based on the ICF framework,emphasizing a holistic understanding of impairments of speech func-tions and activity limitation of communication in children with intellectual disabilities,and highlighting the im-pact of communication activity on children's learning and daily life.In speech rehabilitation therapy and educa-tional rehabilitation settings,individualized intervention strategies should be designed according to the specific characteristics of impairments of speech functions and activity limitation of communication in children with intel-lectual disabilities,focusing on fostering functional communication skills and integrating them into daily life and educational activities.Augmentative and alternative communication technologies,natural context language inter-ventions,visual supports,and peer-mediated interventions might be effective.Conclusion This study has utilized the ICF framework to systematically analyze impairments of speech functions and ac-tivity limitation of communication in children with intellectual disabilities,interms of body functions and struc-tures,activities and participation,and environmental factors.A systematic approach to promoting the develop-ment of speech function and communication activity in children with intellectual disabilities has been proposed within speech rehabilitation therapy and educational rehabilitation settings,including individualized intervention strategies,the application of assistive technologies,the use of visual support,and the implementation of peer-me-diated interventions.
