Style Brazilian Jiu-Jitsu, Judo, Sambo, MMA

A joint lock is a grappling technique involving manipulation of an opponent's joints in such a way that the joints reach their maximal degree of motion and hyperextension.

Contents

In judō these are referred to as kansetsu-waza (関節技, "joint locking technique" [1] ) and in Chinese martial arts as chin na , which literally means "catching and locking". In Korea these are referred to as gwan-jerl-gi (관절기, joint skill) or gwan-jerl-kerk-gi (관절꺾기, joint breaking).

Joint locks typically involve isolating a particular joint, levering it in an attempt to force the joint to move past its normal range of motion. Joint locks generate varying degrees of pain in the joints and, if applied forcefully and/or suddenly, may cause injury, such as muscle, tendon and ligament damage and even dislocation or bone fracture.

In judo, the combining of standing locks with throws is forbidden due to the risk of physical harm to the falling opponent, while Brazilian jiu-jitsu, jujutsu, taijutsu, aikido, sambo, and hapkido allow their use.

Joint locks can be divided into five general types according to which section of the body they affect:

These general types can be further divided into subtypes according to which specific joint(s) they affect, or the type of motion they involve.

Joint locks are commonly featured in all forms of grappling, whether it be in martial arts, self-defense, combat sport or hand to hand combat application. The variants involving lesser levering on a smaller joint (such as wristlocks) are often featured in law-enforcement or self-defense application, where they are used as pain compliance holds. Joint locks that involve full body leverage can on the other hand be used in hand to hand combat to partially or fully disable an opponent, by tearing major joints such as knees or elbows.

Common martial arts featuring joint locks include Aikido, Brazilian Jiu-Jitsu, Catch Wrestling, Eskrima, Eagle Claw, Fu Jow Pai, Hapkido, Hung Gar, Jujutsu, Judo, Sambo, Ninjutsu, Shoot wrestling, and mixed martial arts. They are usually practiced in a maximally safe manner, with controlled movements, and releasing the joint lock once it is apparent that it has been effectively applied. In combat sports, joint locks are used as submission holds, and are intended to force the opponent to submit; the lock will be controlled and held until an opponent submits or a referee recognizes the threat of injury and intervenes. The types of joint locks allowed in competitions featuring them varies according to the perceived danger in their application. Armlocks are generally considered safer, while small joint manipulation and spinal locks are banned in nearly all combat sports.

This is typically done by bending or twisting the head or upper body into abnormal positions. Commonly, spinal locks might strain the spinal musculature or result in a mild spinal sprain, while a forcefully and/or suddenly applied spinal lock may cause severe ligament damage or damage to the vertebrae, and possibly result in serious spinal cord injury, stroke, or death.

<span class="mw-page-title-main">Combat Hapkido</span>

Combat Hapkido is an eclectic modern Hapkido system founded by John Pellegrini in 1990. Taking the next step in 1992 Pellegrini formed the International Combat Hapkido Federation (ICHF) as the official governing body of Combat Hapkido. Later, in 1999, the ICHF was recognized by the Korea Kido Association and the World Kido Federation, collectively known as the Kido Hae, as the Hapkido style Chon Tu Kwan Hapkido. The World Kido Federation is recognized by the Government of South Korea as an organization that serves as a link between the official Martial Arts governing body of Korea and the rest of the world Martial Arts community. The founder of Combat Hapkido was very clear in his statement that he did not invent a new martial art. He stated "I have merely structured a new Self-Defense system based upon sound scientific principles and modern concepts. For this reason Combat Hapkido is also referred to as the "Science of Self-Defense". Combat Hapkido is a new interpretation and application of a selected body of Hapkido techniques. The word "Combat" was added to Combat Hapkido to distinguish this system from Traditional Hapkido styles and to identify its focus as Self-Defense.

<span class="mw-page-title-main">Jujutsu</span> Japanese martial art

Jujutsu, also known as jiu-jitsu and ju-jitsu, is a family of Japanese martial arts and a system of close combat that can be used in a defensive or offensive manner to kill or subdue one or more weaponless or armed and armored opponents. Jiu-jitsu dates back to the 1530s and was coined by Hisamori Tenenouchi when he officially established the first jiu-jitsu school in Japan. This form of martial arts uses few or no weapons at all and includes strikes, throws, holds, and paralyzing attacks against the enemy. Jujutsu developed from the warrior class around the 17th century in Japan. It was designed to supplement the swordsmanship of a warrior during combat. A subset of techniques from certain styles of jujutsu were used to develop many modern martial arts and combat sports, such as judo, aikido, sambo, ARB, Brazilian jiu-jitsu, and mixed martial arts. The earliest recorded use of the word “Jiu-Jitsu” happens in 1530s and is coined by Hisamori Tenenuchi when he officially established the first school of Jiu-Jitsu in Japan. The history of the art during this time is uncertain because teachers kept everything secret to give their art a feeling of importance and then would change the stories of their art to suit their own needs.

Taijutsu is a Japanese martial art blanket term for any combat skill, technique or system of martial art using body movements that are described as an empty-hand combat skill or system. Taijutsu is a synonym for Jujutsu. The words jujutsu, taijutsu, and yawara can be used interchangeably. The term is commonly used when referring to a traditional Japanese martial art but has also been used in the naming of modern martial arts such as Gendai Goshin Jutsu, Yamabujin Goshin-Jutsu, Fuji Ryu Goshindo JiuJitsu and Bujinkan Budo Taijutsu. Taijutsu is similar to Karate but is more focused on the body techniques. More specific names than taijutsu are typically used when describing a martial art: Judo, Aikido as well as Karate and Kenpō.
