Обзор
Wrist extension locks force the hand backward (dorsiflexion), hyperextending the wrist joint and stressing the palmar ligaments and flexor tendons. [1],[2] The gooseneck is the classic wrist extension lock — the attacker bends the opponent's hand backward toward the forearm. Figure-four wrist extensions use a two-on-one grip for additional leverage. Kote-gaeshi in aikido is a throwing technique that uses wrist extension with rotation. [3],[4]

Биомеханический механизм
Primary Action — Hyperextension of the elbow joint — the hips drive upward against the posterior humerus while controlling the wrist
Joints Involved — Elbow (extension beyond normal ROM), wrist (stabilized), shoulder (isolated and controlled)
Force Vector — Posterior-to-anterior force on the upper arm with fixed distal anchor at the wrist creates a lever arm across the elbow
Leverage Principle — Hips act as the fulcrum — the longer the lever (full arm extension), the less force needed to hyperextend
Позиция и вход
From any grip exchange — During grip fighting, isolate the opponent's wrist with two-on-one control and apply sudden flexion or rotation
From guard (gi) — When opponent posts a hand on the mat or chest, trap the wrist and apply downward pressure for the wrist lock
From mount or side control — Opponent posts to escape, trap the wrist against the mat and apply the lock

✓Wrist extension locks bend the hand backward — forcing the back of the hand toward the forearm beyond the wrist's natural extension range (Danaher, New Wave Jiu Jitsu, 2020)
✓The standard wrist extension: control the opponent's forearm with one hand while the other hand pushes the back of their hand toward their forearm — the wrist hyperextends
✓Extension locks are the most common wrist submissions in grappling: they appear during grip fighting, guard passing, and from mount when the opponent posts a hand
✓The extension lock is available whenever the opponent has a flat hand on the mat or against your body — the exposed fingers create the lever for the extension
✓The power comes from the attacker's body weight driving through the hand: the free hand pushes the back of the hand while body weight provides the force through the controlling arm
✓Extension locks work both in gi and no-gi: in gi, the sleeve grip assists control; in no-gi, the bare forearm is controlled directly
✓The transition from grip break to wrist lock is seamless: peeling the opponent's grip open naturally positions the hand for an extension lock
Типичные ошибки
!Pushing the fingers instead of the back of the hand — the force must be applied to the metacarpals (back of hand), not the finger joints
!Not stabilising the forearm — the forearm must be anchored; if it moves with the hand, no extension occurs
!Using finger strength — the extension requires the palm of the attacker's hand against the back of the opponent's hand; full palm contact distributes force
!Applying when the opponent makes a fist — the fist position strengthens the wrist; wait for or create an open hand
!Not recognising the setup — the extension lock appears during grip breaks and hand posting; learn to see these moments
!Cranking rapidly — the wrist breaks before pain signals register; apply gradually
!Attempting from a distance — the attacker must be close enough to control both the forearm and the hand simultaneously

Figure-Four Extension
РодThe figure-four extension wrist lock uses a figure-four grip configuration to hyperextend the opponent's wrist — bending it backward beyond its natural range of motion. [1,2] The attacker grips the opponent's hand with one hand and reinforces with a figure-four by gripping their own wrist, then presses the back of the opponent's hand toward the forearm. [1] The figure-four provides mechanical advantage that makes the lock extremely difficult to resist with wrist strength alone. [1] This is commonly applied when the opponent grips a collar or sleeve in gi grappling. [1,2]

Gooseneck Extension
РодThe gooseneck extension wrist lock bends the wrist backward while curling the fingers downward, creating a shape resembling a goose's neck. [1,2] The attacker grips the back of the opponent's hand and pushes it toward the forearm while simultaneously curling the fingers, compounding the extension pressure on the wrist with flexion pressure on the finger joints. [1,3] This double-action makes the gooseneck particularly painful and difficult to resist. [1] It is commonly applied from wrist control positions in standing or from top positions in ground grappling. [1,4]

Часто задаваемые вопросы
How should I position my hands when applying a gooseneck wrist lock?
Your hands should be positioned absolutely vertical, like in a prayer position, with the opponent's hands held between yours. According to Weapons Defense Academy, avoid taking the hand on an angle or all the way over—keep it strictly vertical for proper technique execution.
What's the correct direction to apply pressure in a gooseneck wrist lock?
You should pull the opponent's hand toward you while pushing their fingers toward their body (toward their nose), and push downward—not upward or sideways. Weapons Defense Academy emphasizes that pushing up or to the side produces no effect; the downward pulling-and-pushing motion is what creates the lock.
How do I prevent my opponent from escaping the gooseneck wrist lock?
Don't let their elbow rise, because lifting the elbow allows them to spin and turn out of the lock. Weapons Defense Academy recommends keeping your hands over the top to control their arm and applying pain if they try to bring their hand up to escape.
Как работает Extension?
Wrist extension locks force the hand backward (dorsiflexion), hyperextending the wrist joint and stressing the palmar ligaments and flexor tendons. The gooseneck is the classic wrist extension lock — the attacker bends the opponent's hand backward toward the forearm.
Откуда происходит Extension?
Wrist extension techniques (kote-gaeshi, 小手返し) are foundational in aikido and Daito-ryū Aiki-jūjutsu, where they are used for both throwing and control. In judo, wrist locks appear in the Kodokan Goshin Jutsu self-defense kata.
