Objective To construct a theoretical framework for early home-based education and rehabilitation for infants and tod-dlers with developmental disabilities,using the bio-psycho-social model of the International Classification of Functioning,Disability and Health(ICF).Methods On the base of integrating ecosystem theory,neuroplasticity theory,family systems theory and rehabilitation concept of World Health Organization,a home-based education and rehabilitation system encompassing biologi-cal,psychological,social and policy dimensions was developed.Results Within the ICF framework,it was set the operational intervention goals for infants and toddlers in dimensions of motor,language,cognition,emotion and social interaction,while personalized goals were formulated in consider-ation of different types of developmental disabilities.Furthermore,a home-based education and rehabilitation sys-tem was designed,including early screening and assessment,development of personalized intervention plans,home-based education and rehabilitation training,continuous monitoring and adjustment,digital empowerment and remote guidance,as well as disability prevention,and early education and rehabilitation.It involved five stag-es:needs assessment,plan development,plan implementation,dynamic assessment and feedback,and summary and referral.Conclusion This study has constructed a five-stage process,providing an effective framework for the comprehensive re-habilitation of infants and toddlers.ICF framework provides both theoretical and practical guidance for early in-tervention in infants and toddlers with developmental disabilities.
