These pieces of equipment again are much more sophisticated than many of the pieces of older equipment you have in some of your other sites. The various pieces of padding can be used to individualize each chair for the specific person who uses it. Every person has a slightly different need, so each chair can be tailor-made to assist in correct body alignment.
The seatbelts are the newer type as well. Also the chair padding is much better and the second metal ring outside the wheel is so the people can propel themslves independently by pulling on it (usually wearing fingerless gloves so as to avoid blisters while not losing finger dexterity).
"Fantasy" is one thing. Making assumptions about what happened in these places and then stating them publicly can be a disservice to the people who lived there and to the people who worked there. There is enough that is emotionally charged about having a psychiatric disability without turning it against the people who lived there and their staff. That is a form of abuse in itself, by caricaturizing the people involved and making assumptions without really learning about them.
There's a lot of pain and sadness involved in cancer wards (and a LOT more death), but you don't get the same comments from people with the lookie-loos and few people are chasing around looking for orbs on deserted cancer wards because it's a little more clear that it's bizarre and tasteless and intrusive. If people would turn it around and think about what it would be like to have been on a cancer ward and then years later find out that people are running around where you received treatment, looking for ghosts and making assumptions about "the cruel people who did that God-awful archaic torturous chemotherapy on those poor pitiful wretches" it might make it look a little different. People think it's OK to intrude on the privacy of people who had psychiatric problems but are generally a little more reticent to stare at someone who had an arm amputated or who lost a child in childbirth. It's not quite a double standard, but it's danged close.
Most, if not all, developmental centers have areas for the repair of wheelchairs. A large number of people who live at these facilities use wheelchairs to get around, so it is more than just an inconvenience if one breaks down.
