The International Classification of Functioning, Disability and Health (ICF) is a framework developed by the World Health Organization (WHO) to describe and measure health and disability. It emphasizes the interaction between health conditions and various factors, including personal and environmental influences, providing a comprehensive view of an individual's functioning. ICF categorizes functioning and disability into two main components: body functions and structures, and activities and participation. This classification helps healthcare professionals, researchers, and policymakers understand the impact of health conditions on individuals' lives, facilitating better support and interventions tailored to their needs.
