Thường Ðức Camp in the context of Quảng Nam Province

A stress position, also known as a submission position, is a form of punishment that places the human body in such a way that a great amount of weight is placed on very few 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 rapid onset of muscle fatigue and tear.

Forcing prisoners to adopt such positions is a torture technique that proponents claim leads to extracting information from the person being tortured.
