Technique Interrogation 2: 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 his feet, then squat so that his 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 a method of ill-treatment used for extracting information or as a punishment, amounting to torture.

A Viet Cong prisoner captured in 1967 by the U.S Army awaits interrogation. He has been placed in a stress position by tying a board between his arms.
