Spastic is still used in a medical sense (spasms). I think all the others are done now. The individual condition is usually specified, rather than a catch-all.
Woofgang, oh right. I think it generally referred to cerebral palsy sufferers - so not just learning disabilities - but I'm sure you know that. Having said that, the term has been used (by idiots) as slang to refer to people with learning difficulties.
Scrivens, "spastic" is a medical term for abnormally high muscle tone that does not relax. the opposite of that is "flaccid" these terms became open to misunderstanding so the terminology used now is high or raised tone and low or lowered tone. one of the kinds of cerebral palsy results in tight muscles, rather like some stroke victims have, so they were commonly known as "spastics"
nothing at all to do with things that dont work properly
