The International Classification of Functioning, Disability and Health provides a theoretical model for understanding the impact of injuries from biological, psychological and social perspectives. It provides a theoretical framework for exploring physical health, individual activities and individual social functions.
ICF consists of two parts. The first part is about function and disability, including body function (represented by the letter "B") and body structure (represented by the letter "S"), activities and participation (represented by the letter "D"). The second part is background factors, which mainly refers to environmental factors (represented by the letter "E").
ICF adopts alphanumeric coding system, so it can code a wide range of health-related information (such as diagnosis, function, disability status, etc.), and provide a unified and standard language and framework for clinic to describe patients' health status and health-related conditions; At the same time, using this standardized common language can make different disciplines and fields in the world communicate with each other.
ICF regards the classification of function and disability as a process of action and change, and provides a multi-angle method. The functional state of an individual is the interaction and complex relationship between health state and situational factors. Intervention in one project may lead to changes in one or more projects. This interaction is usually two-way.
