Introduction: Cerebral palsy (CP) is the leading cause of childhood physical disability worldwide. In Sri Lanka, paediatric rehabilitation services are limited mainly to tertiary centers. Community-based rehabilitation (CBR) has been proposed as a strategy to improve access, reduce financial burden and strengthen family involvement. Evidence regarding its efficiency and contextual applicability remains heterogeneous. Objectives: To synthesise evidence on the efficiency , functional outcomes, caregiver impact and implementation considerations of CBR for children with CP, with specific relevance to Sri Lanka. Methods: A narrative review was conducted using PubMed, Google Scholar, the Cochrane Library and selected grey literature sources, published between January 2005 and July 2025. Eligible designs comprised randomised controlled trials, quasiexperimental, observational and qualitative studies, systematic reviews and implementation reports. Findings were synthesised thematically across cost-effectiveness, functional outcomes, caregiver impact, community engagement and implementation factors. Results: The results included 34 peer-reviewed studies and 6 grey literature sources. Seven studies reported reduced household costs without loss of functional gains. Fifteen showed motor and daily activity improvements comparable to facility-based care, while twelve documented reduced caregiver strain and improved parental competence.Task-shifting and community engagement expanded service reach in rural settings. Structured training, supervision and referral mechanisms were identified as critical for sustainability . Conclusions: Evidence suggests that structured, supervised CBR may improve access and reduce financial barriers while maintaining functional outcomes in selected contexts. However, economic efficiency is contingent on programme quality and integration within existing health systems. In Sri Lanka, careful pilot implementation and context-specific economic evaluation are needed before large-scale adoption.
