A wristlock is a
The wristlock is a technique that can be applied from a stand-up position, simply by grabbing the opponent's hand and twisting and/or bending it in a non-natural direction. It is considered to be a relatively safe technique to practice with a willing opponent,[4] but if applied suddenly and/or forcefully, a wristlock can cause ligament tears or possibly even dislocation or bone fractures.
Types
Rotational
A rotational wristlock (in budo referred to as kote hineri, and in Aikido referred to as a type of sankyō, 三教, "third teaching")
Supinating
The supinating wristlock (in
A properly executed lock of this type does not apply torque to the wrist itself. In practice, the bones of the forearm and, eventually, the shoulder are the focus of the lock. If performed correctly, this technique will break the opponents wrist, elbow and dislocate the shoulder. In practice, uke will turn over his own arm in order to prevent his wrist from breaking. The goal of almost all throws executed via joint/bone manipulation, at least from the perspective of some classical (koryu) martial arts, is to break or dislocate a limb(s).
Pronating
The pronating wristlock (in budō referred to as kote mawashi, 小手回し, "forearm turn", and in Aikido referred to as nikyō, 二教, "second teaching") is similar to the supinating wristlock except that it is reversed in direction, known as 'internally rotating' the wrist. The hand becomes maximally
Hyperflexing
A hyperflexing wristlock (commonly referred to as a "gooseneck")(in budō referred to as tekubi gatame, 手首固め, "wrist lock") involves forcing the wrist into
Hyperextending
The "hyperextending wristlock" is often combined with a
Adductive
An adductive wristlock (in budō referred to as kote hono gaeshi, "partial forearm return", part of aikido's nikyō, or second teaching, in its ura form) involves forced ulnar deviation of the hand. It is typically applied by twisting the opponent's arm so that the opponent's palm points laterally and the elbow is slightly bent. The hand is then grabbed using one or both hands, and the wrist is forced downwards, hence reaching the limit of possible ulnar deviation, and creating a potent joint lock on the wrist joint. To avoid damage, it is possible for the opponent to drop down to the ground, and alleviate the pressure. The adductive wristlock is often taught as a self-defense technique against grabbing. It is also commonly referred to as a "Z-Lock" because the bend of the arm forms a Z. In some parts of America this is also called the "Goose Neck" because the bend of the arm forms a S.
