Many disabilities and chronic medical conditions will never be cured.
Persons with disabilities are quite capable of participating in society, and the practices of confinement and institutionalization that accompany the sick role are simply not acceptable.
Given this reality, if disability were more commonly recognized and expected in the way that we design our environments or our systems, it would not seem so abnormal.
This is consistent with the role of the person with a disability as sick.
As Professor David Pfeiffer has put it, "...paralyzed limbs may not particularly limit a person's mobility as much as attitudinal and physical barriers. What, it is asked, is the normal way to be mobile over a distance of a mile?
Is it to walk, drive one's own car, take a taxicab, ride a bicycle, use a wheelchair, roller skate, or use a skate board, or some other means? "Most people will experience some form of disability, either permanent or temporary, over the course of their lives.
THE DISABILITY MODEL has taken hold as the disability rights and independent living movements have gained strength.
This model regards disability as a normal aspect of life, not as a deviance and rejects the notion that persons with disabilities are in some inherent way "defective".
Historically, it gained acceptance after World War II when many disabled veterans needed to be re-introduced into society.
