Lecture Content
I. The Medical Model of Disability
The medical model understands disability as a deficit, impairment, or pathology located in the individual body. The person is disabled because of their condition -- paralysis, blindness, cognitive impairment, or chronic illness. The goal of medicine under this model is to cure, correct, or rehabilitate, making the person as "normal" as possible. The physician is the authority, and the patient is the object of intervention.
Several assumptions are embedded in this model. Health is equated with normal functioning, and disability is understood as deviation from the norm. Disability is treated as inherently negative, a problem to be solved. The non-disabled body serves as the standard against which all bodies are measured, and successful treatment means restoring or approximating normalcy.
The medical model has genuine strengths. It drives research into treatments, assistive technologies, and rehabilitation. It provides a framework for clinical diagnosis and intervention. And it enables access to healthcare resources and insurance coverage, since a diagnosis is often required for services.
However, the medical model also has significant limitations. It locates the "problem" in the individual rather than in the environment or society. It pathologizes difference and can be experienced as dehumanizing. It ignores the ways that disability is created by social barriers rather than solely by biological conditions. And it reduces the person to their impairment, failing to see the whole person and their lived experience.
II. The Social Model of Disability
The social model emerged from the UK disability rights movement in the 1970s and 1980s. Mike Oliver coined the term in 1983, and the Union of the Physically Impaired Against Segregation (UPIAS) articulated its core claim in 1976: "Disability is something imposed on top of our impairments by the way we are unnecessarily isolated and excluded from full participation in society."
The social model draws a crucial distinction between impairment and disability. Impairment is the biological or functional condition -- paraplegia, deafness, intellectual disability. Disability is the social disadvantage imposed on people with impairments by an inaccessible, exclusionary society. As the movement's central insight puts it, "People are disabled by society, not by their bodies." A wheelchair user, for example, is impaired by their spinal cord injury but disabled by the absence of ramps, accessible transportation, and inclusive design.
The implications are transformative. The "problem" is not the person but the environment, the architecture, the policies, and the attitudes. The solution is not cure but access, accommodation, inclusion, and civil rights. Disability is understood as a form of social oppression analogous to racism or sexism, and people with disabilities are recognized as a minority group with rights, culture, and political agency rather than a collection of patients.
Critiques of the social model have emerged from within disability studies. It can minimize the reality of pain, fatigue, and suffering that some impairments involve. Not all aspects of disability are socially constructed: some conditions cause intrinsic distress regardless of social barriers. The sharp impairment/disability distinction may be too neat, since biology and society are always entangled. Tom Shakespeare's relational model proposes that disability arises from the interaction between individual impairment and social context, with neither sufficient alone to explain the experience.

Right panel "The Social Model": the same figure in the center with arrows pointing outward to labels "Inaccessible Buildings," "Discriminatory Attitudes," "Exclusionary Policies," "Lack of Accommodations," and "Segregated Education." The surrounding environment is labeled "The problem is in the society." Below: "Goal: change the world to include the person." A bridging note at the bottom: "The relational model (Shakespeare) recognizes that both impairment and social barriers contribute to disability -- the interaction is what matters."</image>
III. The Disability Rights Movement: A Brief History
People with disabilities have been institutionalized, sterilized, and killed throughout history. The eugenics movement of the early twentieth century subjected people deemed "unfit" to forcible sterilization, including those with physical and intellectual disabilities. Buck v. Bell (1927) saw the US Supreme Court uphold compulsory sterilization, with Justice Oliver Wendell Holmes Jr. writing, "Three generations of imbeciles are enough." The Nazi T4 program (1939-1941) systematically murdered approximately 70,000 or more people with disabilities, serving as a precursor to the Holocaust. Through the mid-twentieth century, people with intellectual and developmental disabilities were routinely placed in large residential institutions, often in appalling conditions, as exposed by journalist Geraldo Rivera's 1972 investigation of Willowbrook State School.
The civil rights era brought disability activism to the fore. Section 504 of the Rehabilitation Act (1973) was the first US federal law prohibiting disability discrimination in federally funded programs. Its implementation was delayed until disability activists staged a twenty-five-day sit-in at the San Francisco federal building in 1977 to force enforcement. The Independent Living Movement challenged the assumption that people with disabilities need institutional care, advocating for community-based living, personal assistance, and self-determination. Pioneering leaders like Ed Roberts and Judy Heumann reframed disability as a civil rights issue.
The Americans with Disabilities Act (ADA, 1990) was landmark civil rights legislation prohibiting discrimination on the basis of disability in employment, public accommodations, transportation, and telecommunications. The "Capitol Crawl" of 1990, in which activists abandoned their wheelchairs and crawled up the Capitol steps, dramatized the demand for passage. The ADA has transformed the built environment and legal landscape, though enforcement remains inconsistent. Global developments include the UN Convention on the Rights of Persons with Disabilities (CRPD, 2006), the Accessible Canada Act (2019), and the UK Equality Act (2010). The disability rights movement continues to evolve, increasingly addressing intersecting forms of oppression involving race, gender, class, and disability.
IV. Ableism in Healthcare
Ableism is discrimination and social prejudice against people with disabilities, based on the assumption that non-disabled bodies and minds are the norm and the ideal. It manifests in clinical settings in several troubling ways.
Assumptions about quality of life are among the most consequential. Clinicians consistently rate the quality of life of people with disabilities as lower than people with disabilities rate it themselves. This mismatch -- known as the "disability paradox," in which people with serious disabilities often report high life satisfaction -- surprises clinicians and able-bodied observers but has been documented repeatedly. The consequences are serious: treatment decisions, resource allocation, and organ transplant eligibility can all be influenced by clinicians' assumptions about what life with a disability is "worth."
Communication barriers arise when physicians speak to caregivers rather than the patient, fail to provide accessible communication formats, or assume intellectual disability where none exists. Diagnostic overshadowing occurs when all symptoms are attributed to the known disability rather than investigated as new complaints -- for example, when a patient with Down syndrome presenting with fatigue is assumed to be "just tired" rather than evaluated for hypothyroidism. Physical inaccessibility, including exam tables that are too high, imaging equipment that cannot accommodate wheelchairs, and inaccessible office buildings, creates practical barriers to care. Many physicians receive minimal education on disability and may feel uncomfortable, paternalistic, or uncertain in encounters with disabled patients.
The impact on healthcare outcomes is substantial. People with disabilities experience significant health disparities: higher rates of chronic disease, lower rates of preventive care, and delayed diagnoses. These disparities are not caused by disability itself but by ableism in the healthcare system.

Base level "Structural Ableism": inaccessible facilities, policies that exclude, insurance barriers, lack of disability-inclusive research, built environment that assumes non-disabled bodies. Second level "Institutional Ableism": medical education that barely covers disability, clinical guidelines that undervalue disabled lives, organ allocation criteria that discriminate, quality-of-life metrics that embed ableist assumptions. Third level "Interpersonal Ableism": clinicians speaking over or around disabled patients, diagnostic overshadowing, pity or discomfort rather than respect, assumptions about suffering and quality of life. Top level "Internalized Ableism": disabled people absorbing societal messages that their lives are lesser, that they are burdens, that they should be grateful for any care received. A side note: "All levels interact and reinforce each other; addressing ableism in medicine requires intervention at every level."</image>
V. Disability, Ethics, and the Goals of Medicine
Disability studies challenges medicine to reconsider what "normal" means. Who defines it? What is the standard against which bodies are judged? The concept of "normal" is historically constructed, emerging in the nineteenth century alongside statistics and the bell curve, as Lennard Davis argues in Enforcing Normalcy (1995). The medical pursuit of normalcy can be harmful, as illustrated by debates over cochlear implants in Deaf communities, growth hormone for short stature, and cosmetic surgery for Down syndrome facial features.
Deaf culture presents a particularly powerful challenge to the medical model. Many Deaf people do not consider themselves disabled; they are a linguistic and cultural minority. Deafness is understood not as a deficit but as a difference, and American Sign Language is a complete, natural language. Cochlear implants are viewed by some in the Deaf community as a threat to Deaf culture and identity. This challenges medicine to ask: Is the goal always to "fix"? Who decides what needs fixing?
Prenatal testing and selective abortion intersect with disability rights in complex ways. Prenatal screening can detect conditions such as Down syndrome, spina bifida, and cystic fibrosis. The disability rights critique notes that high termination rates for conditions like Down syndrome (estimated at 60-90% in various countries) reflect societal devaluation of disabled lives. The tension between reproductive autonomy and disability justice -- between the right of parents to make informed decisions and the message sent by systematically preventing the birth of people with certain conditions -- requires holding multiple values in tension rather than resolving them simply.
End-of-life decision-making also intersects with disability rights. Disability activists have been vocal opponents of legalized assisted dying in many jurisdictions, concerned that in a society that devalues disabled lives, assisted dying may become a tool of discrimination rather than autonomy. The "better dead than disabled" assumption -- the fear that clinicians and society will pressure disabled people toward death -- underlies much of this concern. Not all disability organizations hold this view, and the debate is internal and nuanced.
VI. Toward Disability-Competent Medicine
Disability-competent care requires accessible physical environments and communication, clinicians trained in disability history, culture, and the social model, clinical decision-making that does not assume disability equals suffering, inclusion of people with disabilities in research, medical education, and healthcare leadership, and a commitment to asking disabled patients about their experience, their goals, and their expertise about their own bodies.
The disability rights motto -- "Nothing about us without us" -- insists that policies, programs, and practices affecting disabled people must involve disabled people as leaders, not just recipients. Applied to medicine, this means including disabled voices in clinical guidelines, ethics committees, medical school curricula, and health policy.
Intersectionality is essential to disability-competent medicine. Disability intersects with race, gender, sexuality, class, and immigration status. A Black wheelchair user, a Deaf transgender person, a low-income person with chronic pain -- each faces compounding forms of marginalization. Disability-competent medicine must be intersectionally aware.
