Models of disability and their relation to accessibility is a fascinating post by Martyn Cooper. The post conclusion will give you an idea of the different models of disability the article discusses:
Our models of disability are important, they shape our attitudes and impact on how effectively the needs and preferences of disabled people are met in design. The medical model is now widely seen as outmoded and a perpetuator of discriminatory attitudes. The social model has had widespread influence. It is important in accessibility considerations because it recognises the importance of the context of the users and supports the view of accessibility as a relationship property; in the case of web accessibility the relationship being between the diversity of users and the web resource or application. Functional models have been asserted as the most useful in design and development and the potential of these for personalisation and analytics highlighted.
