It is well known that disabled people are among the most marginalised and oppressed groups within society. Their exclusion has been reinforced by discriminatory attitudes and practices that promote segregation and prejudice. The World Programme of Action Concerning Disabled Persons was promoted by the United Nations in 1982, and was later followed by the Standard Rules on the Equalisation of Opportunities for Persons with Disabilities (UN 1993). Internationally, these were means by which to highlight the need for prevention of disability, rehabilitation and equalisation of opportunities for disabled people. Included in rehabilitation are measures to compensate for loss or limitation of function - one of these being through technical appliances. It is also recognised that a precondition to the equalisation of opportunities is the provision of support services - including assistive devices - to disabled people, because they enable the individuals participation on equal terms.
