Do padded cells still exist in psychiatric units?
Yup, they do, most hospitals also have at least a few padded rooms too, (I was placed in one once when I was having a violent Epileptic seizure), not that it mattered either way, during a seizure I don’t feel pain. Most units also have arm and leg restraints, and also sedatives too, though the humanity and civility of many of these methods is questionnable.
