The International Classification of Functioning, Disability, and Health (ICF) provides a standard language for the description and classification of health-related states. It is a classification of health-related factors that can be used to describe changes in body function and structure, as well as the physical capacities associated with each health condition.
These factors are classified from several perspectives, including body, individual, and societal, by means of two lists: a list of body functions and structure, and a list of activities. The term “disability” is an umbrella term that includes functional impairments and activity restrictions. The classification scheme also lists environmental factors that may interact with these factors.
The ICF defines disability as
“the outcome of the interaction between a person with an impairment and the environment and attitudinal barriers she/he may face.”
