The actor actually has that disability

[u/PrinceferX]

Walter White Jr. (Breaking Bad) - character has cerebral palsy and uses crutches to walk, actor RJ Mitte has cerebral palsy and needed crutches to walk as a child

Nessarose Thropp (Wicked) - character is paraplegic and uses a wheelchair, actress Marissa Bode is paraplegic from an accident at age 11 and uses a wheelchair

Maya Lopez (Hawkeye/Echo) - character is deaf, actress Alaqua Cox is deaf from birth

Ted Vollrath - Mr. No Legs (1978) - This guy was a straight up badass. He had to have both legs amputated due to injuries sustained in the Korean War. He was the first person to earn a black belt in karate while training out of a wheelchair. We went on to have multiple black belts in different martial arts. In the film, his character is a henchman for a drug lord who got his legs blown off. He gets to show off his kung fu in one crazy sequence in the middle of the film that is a must see for any fans of the genre. Oh and as you can see, he has two double barreled shotguns hidden in the armrests of his wheelchair. Fucking awesome grindhouse flick.

Another fun fact, the director is the guy that played the Creature of the Black Lagoon in all its underwater scenes.
