How do the World Health Organization (WHO) definitions of terms related to restorative care compare with those provided by Nagy?
The WHO defines “impairment” as the loss of function at the organ level, “disability” as the restriction or lack of ability to perform an activity a normal person can perform, and “handicap” as the inability to perform life roles due to disability. The term “handicap” was thought to carry a stigma, so the definitions were modified by Nagy, who used the term “functional limitation” for loss of the ability to perform a specific activity and the term “disability” for the loss of a role.
