Were wheelchairs available at the time?
I watched the trailer for this and notice there's a nonverbal autistic kid character. He's in a wheelchair that looks very odd, similar to a rocking chair. Were wheelchairs like these available in 1886? Were there as functional as the trailer and teaser shows?
Teaser trailer for context:
