I've never been restrained. In all of my times in the hospital (quite a few), I never saw physical restraints used. I did see patients who were moved into a quiet room for a time and I'm assuming given medication until they were calm enough to not pose a physical threat to the staff or other patients around them. While in the quiet room, they were not locked in, but rather simply supervised by a staff person who stayed with them constantly until they were able to go back to their own room - usually only an hour or so. The hospital also went over treatment plans and possible interventions upon admission, and this process was part of what was explained.
