International classification of impairments, disabilities, and handicaps
Presents a system for classifying impairments, disabilities, and handicaps with the aim of improving information on the consequences of disease. Three independent classifications are presented. Impairments are classified according to abnormalities of body structure and appearance or disturbances of organ or system function resulting from any cause (disturbances at the organ level). The classification of disabilities reflects the consequences of impairment in terms of functional performance and activity by the individual (disturbances at the individual level).
