Which technique is defined as gaining control by applying pressure or leverage on a joint until movement is impossible, prompting verbal compliance?

• A. Balance displacement
• B. Mechanical compliance
• C. Pain compliance
• D. Joint manipulation

Answer: (B)

Mechanical compliance is about gaining control by applying pressure or leverage on a joint until movement is mechanically blocked, which often prompts verbal compliance to avoid further force. This approach uses the joint’s physical limits to prevent motion, rather than relying mainly on pain. Pain compliance, by contrast, uses painful stimuli to compel cooperation without necessarily immobilizing a joint. Balance displacement targets the suspect’s stance and stability, not the joint itself. Joint manipulation involves repositioning a joint for alignment or relief, not holding it fixed to stop movement.
