ABSTRACT
Representatives of disabled people reappropriate very often foreign categorizations or categorizations used by international institutions included in international resolutions or in reports of international experts. The reports of the commissions of international experts, the international documents approved during this period, play a key role within the categorization changes of the disabled group at the international and national levels. The focus on the highly discriminatory labour market brings some doctors to define the group of disabled people on the basis of the professional disadvantage they experience because of their disability. In the middle of the 1940s, the international experts are in a great uncertainty regarding the manner of defining the 'disabled'. In England, the depreciation of the work of a disabled person on the labour market is taken into account to evaluate the degree of wage-earning incapacity. That generates a very important rise of the declarations of disability submitted to the administrative institutions during the 1930s.
