Stress position
A stress position, also known as a submission position, places the human body in such a way that a great amount of weight is placed on just one or two muscles. For example, a subject may be forced to stand on the balls of their feet, then squat so that their thighs are parallel to the ground. This creates an intense amount of pressure on the legs, leading first to pain and then muscle failure.
Forcing prisoners to adopt such positions is an enhanced interrogation technique used for extracting information.
