They still had the chest restraint in 2009 at least. Most my restraints were 5 point. I heard stories of some people staying in them for 15-18 hours.
In treatment centers they would put me in a bear hug and hold me in their lap against a wall and then if it escalated from there they’d hold me on the floor with several other people. I was also restrained against the wall.
I think it’s gotten a lot better in the past 10 years with the news and smartphones and viral videos and they don’t do that stuff as much anymore.
