A universal framework for comprehending and describing functioning and disability is the International Classification of Functioning, Disability, and Health (ICF) developed by the World Health Organization (WHO). ICF Core Sets, a procedure for creating core sets of ICF categories, were developed by WHO and the ICF Research Branch to increase the ICF’s applicability for everyday use. By offering a list of fundamental categories pertinent to certain medical conditions and healthcare environments, ICF Core Sets make it easier to describe functioning, for instance in clinical practice. These ICF categories were chosen from the complete ICF as part of a scientific procedure based on preliminary research and input from a broad team of specialists.
