This revision is to be titled as International Classification of Impairments, Activities and Participation. Impairment is defined as abnormality of structure or function of the body or an organ.
Disability is defined as a restriction of activities as a result of impairment.
Handicap is defined as a social disadvantage resulting from either impairment or disability. This classification is not linear any more and suggests interaction of the health condition and the contextual factors simultaneously on impairment, activity and participation. The latest revision still has deficiencies such as poor differentiation of boundaries between impairment, activity and participation, as well as between ICD and impairment classification. The level of details to define different segments is poor. The ease of its applicability in all different situations is also suspect.
