Spinning (also called Rotational Therapy)

A person (the mental patient) was placed in a “rotational chair,” often with a box around their head or body to hinder or obstruct their sight, and then spun by hand until they experienced vertigo, sedation, nausea, and vomiting or uncontrollable bowel movements. Spinning was a way to "shock people back to sanity". Sometimes the spinning would last for hours.
