Disability in SF

Some SF works that center around women and disability:

• "The Girl Who Was Plugged In"
• "Melora" - Star Trek: Deep Space 9 episode. A scientist who uses a robotic exoskeleton. Her disability becomes her strength when gravity fails on the ship. "The crew welcomes Ensign Melora Pazlar, a cartographer on a mission to chart the Gamma Quadrant. Melora is an Elaysian, a species from a planet with very low gravity, and because of this, she must use a wheelchair and braces to get around in "normal" conditions."
• "That Only a Mother", Judith Merril, short story about mutation and the effect of nuclear impact on genotype.
• The Jenny Casey series, by Elizabeth Bear, features a female main character with a bionic, prosthetic arm.
• "Blue Champagne" by John Varley features a quadriplegic woman whose golden exoskeleton helps her use her arms and legs, and also helps her become a celebrity.

• A short story about implications of a society where 75% of the people have disabilities due to genetic drift. Airships, low tech post apocalpytic scenario where disabled people actually survive. What was this story and who wrote it?
