Critical disability studies have become over the last three decades an interdisciplinary academic field that introduces a plural and diverse path to understanding disability. These studies focus on a series of theoretical developments that privilege cultural, discursive, and relational understandings of disability, connecting the aspirations of people with disabilities with the agendas of feminist, queer, postcolonial, poststructuralism and posthuman studies. This work aims to outline the epistemological contributions of these studies through the identification of theoretical axes that have been consolidated: power, production of bodies and internalized oppression; intersectionality and multiple identities; and posthuman assemblages. The contribution of these axes lies on the one hand, in the departure from the disability-impediment binary characteristic of the more conventional social studies of disability, which allows us to understand the variability of experiences of disability, and, on the other hand, it makes disability concept strategic to explain the ways in which subjects are produced in current societies.
