The Aoki Lock is a specific type of twisting ankle/foot lock, popularized by Japanese MMA fighter and grappler Shinya Aoki. It's often initiated during transitions, particularly when an opponent attempts to turn away or stand up from a grappling exchange (like escaping back control or a takedown attempt). The attacker secures the opponent's leg, typically below the knee, and applies a figure-four or similar grip to the foot/ankle, using body weight and leverage (often by falling back or sitting through) to generate powerful twisting pressure. This lock primarily attacks the ankle joint but can also place significant stress on the knee.
