Обзор

Cervical extension cranks force the opponent's head backward, hyperextending the cervical spine. ^[1],[2] The can opener (from inside closed guard) is the most common example — the attacker clasps hands behind the opponent's head and drives downward, forcing the chin toward the chest and the cervical spine into extension. Cervical extension cranks are prohibited in most grappling rule sets due to spinal injury risk. ^[3],[4]

Биомеханический механизм

Primary Action — Compression of the neck structures — restricts blood flow or airway depending on technique application

Joints Involved — Cervical spine, surrounding musculature, and vascular structures of the neck

Force Vector — Directed compression against the neck from the choking limb or body position

Finishing Mechanic — Sustained pressure causes either vascular occlusion (unconsciousness) or tracheal restriction (breathing difficulty)

Позиция и вход

From back control with seatbelt — Establish hooks or body triangle, slide choking arm under the chin, connect hands and squeeze

From turtle top (back take) — Break down the turtle, insert hooks, secure seatbelt grip, slide to back control and apply the choke

From standing back clinch — Secure rear body lock, drag opponent to the mat while inserting hooks, transition to choking position

Заметки по тренировке

✓The cervical extension crank forces the opponent's head backward, hyperextending the cervical spine — the chin is lifted and the head is pushed posteriorly, stressing the anterior neck structures (Paulson, Shoot Wrestling, 2007)

✓Extension cranks stress the anterior longitudinal ligament, the intervertebral discs, and the trachea — the neck is forced beyond its comfortable extension range

✓Common positions: from front headlock (lifting the chin while controlling the body), from mount (pressing the chin backward), or from standing (lifting under the chin in a clinch)

✓The cervical extension crank is one of the most dangerous neck submissions: the cervical spine is more vulnerable in extension than flexion — less muscular and ligamentous protection exists posteriorly

✓The can opener from closed guard is a form of cervical extension crank: the attacker grips behind the head from inside the guard and extends backward, forcing the head into flexion (not extension) — but the principle of using forced end-range cervical movement is shared

✓In catch wrestling and submission grappling, cervical extension cranks are legitimate submissions — the anterior neck structures are painful when stretched

✓Medical research warns that cervical extension is the most dangerous direction for the spine: the spinal cord has less space during extension, and disc herniations can occur posteriorly

Типичные ошибки

!Applying cervical extension explosively — the anterior structures of the neck are vulnerable and lack the muscular protection of the posterior chain; slow application is essential

!Not stabilising the opponent's body — the torso must be controlled so the extension force focuses on the cervical spine rather than moving the entire body

!Using cervical extension in casual training without agreement — this is a dangerous technique; only apply with experienced partners who have consented

!Confusing extension with flexion — extension tilts the head backward (chin up); flexion tilts forward (chin to chest) — the mechanisms and risks are different

!Holding the extension at end range — once the opponent taps, release immediately; holding end-range extension risks permanent injury

!Applying from positions without control — cervical cranks require positional dominance to be effective and controlled

!Not understanding the injury mechanism — cervical extension can damage discs, ligaments, blood vessels, and the spinal cord; treat this technique with the seriousness it demands

Face Crank

Род

The face crank applies pressure across the opponent's face — typically the chin, jaw, or nose — to force cervical hyperextension and create intense pain. [1,2,3] The attacker clasps hands under or across the face and pulls upward or backward, driving the chin toward the ceiling and hyperextending the cervical spine. [1,4] Face cranks are often applied from back control, mount, or north-south when the opponent tucks their chin to defend chokes. [1,5] While primarily a pain submission, sustained face cranking can cause cervical spine injury, making it a dangerous technique that is banned or restricted in some competitions. [1,6]

Nelson Neck Crank

Род

The Nelson neck crank uses a half-nelson or full-nelson position to drive the opponent's chin toward their chest (flexion) or force the head sideways, creating cervical spine pressure. [1,2] In the full nelson, both arms thread under the opponent's armpits and lock behind the head, then push the head forward and down. [1] The half-nelson uses one arm behind the head while the other controls the body. [1,3] Nelson cranks are common in wrestling and are applied from back control, side control, or during turtle attacks. [1]

Rear Neck Crank

Род

The rear neck crank from back without hooks is a cervical-spine submission applied from a partial back position — chest-to-back contact established, but no hooks or body triangle. [1] Rather than relying on positional control, the attacker uses upper-body grips alone to crank the cervical spine. [1,2] In the cervical-extension form, the hands gable-grip behind the opponent's head (or the radius bone of the forearm presses under the cheekbone) and drive the chin upward and back while the chest pulls in the opposite direction, forcing extension at the cervical spine. [2] Without hooks, the attacker trades positional stability for speed of attack, making this common in scramble situations and transitions; the absence of leg control means the opponent can potentially rotate free, so the technique requires rapid application. [2,3]

Часто задаваемые вопросы

How do you set up a cervical extension crank from back control?

From back control, you can apply the crank by getting under the chin and using punches or positioning to control the opponent's head before cranking the neck extension. The key is to prevent your opponent from turning the wrong way out of back control, which can trap them in the submission.

What should I do with my arms when caught in a neck crank?

When caught in a cervical extension crank, it is very important to relax your arms rather than tense them, as this can help you escape or reduce injury before tapping.
