Crippled

Crippled: A medically outmoded and politically incorrect term that implies a serious loss of normal function through damage or loss of an essential body part or element.

However, in the not-so-distant past there were US federal funds appropriated for "crippled children."

The word "cripple" is of Anglo-Saxon origin, from "creopan" meaning "to creep." Someone who was crippled, from an oxcart rolling over his leg, had to creep along. There is a tendency in medicine to prefer words of Greek and Latin ancestry to those of Anglo-Saxon descent.
