Pain compliance is the use of painful stimulus to control or direct an organism. The stimulus can be manual (brute force, placing pressure on painful areas, or use of painful hyperextension or hyperflexion on joints), use tools such as a whip or electroshock weapon, or use chemicals such as tear gas or pepper spray. The purpose of pain compliance is to direct the actions of the subject, and to this end, the pain is lessened or removed when compliance is achieved. This provides incentive to the subject to carry out the action required.
