This model acknowledges that disability is a universal human experience, is etiologically neutral, and it lies on a continuum from no disability to complete disability.[1]The contextual factors affecting person's health include real-life environment, social interactions, and social participations.[1]Every healthcare personel need to understand and appreciate that patient perceives his health through the lenses of his daily life impacted by the environment.[1]This course provides an introduction to the International Classification of Functioning, Disability, and Health (ICF) and review the changes and progress in conceptualising and measuring disability.
