Community-based rehabilitation (CBR) has changed considerably over 4 decades, resulting in a rights-based approach, holding local authorities accountable for service delivery. For medical rehabilitation in low-resource countries, there is concern about how this service gap will be covered. The CBR community continues to strengthen the evidence base for CBR implementation, acknowledging its extensiveness and variety on the ground. The creation of standardizing tools favors this process because it provides the building blocks to scale up, setting standards for implementation research. Finally, an International Classification of Functioning, Disability, and Health–based assessment and intervention model for CBR is proposed.
