A wristlock is a 2006 . competition. Wristlocks are also used by Law Enforcement and Military as Pain Compliance Holds . The wristlock is a technique that can be applied from a 2006 ., but if applied suddenly and/or forcefully, a wristlock can cause Ligament tears or possibly even Dislocation or Bone Fracture s. ROTATIONAL WRISTLOCK A rotational wristlock (in 2006 .is a very common type of wristlock, and involves forced supination or pronation of the wrist, and is typically applied by grabbing and twisting the hand. The Wrist Joint does not allow rotating motion, and the force is transferred to the forearm causing Radioulnar rotation, eventually resulting in a joint lock on the Radioulnar Joint . Once the Radius and Ulna have been brought to their extreme positions, further twisting motion will put severe torque on the Wrist . In Martial Arts , standing rotational wristlocks are often accompanied by the opponent willingly Throwing him or herself to escape or alleviate the lock. Supinating wristlock The supinating wristlock (in 2006 . is a rotational wristlock, and arguably the most common wristlock. It involves rotating the hand so that it becomes maximally supinated, often referred to as 'externally rotating' the wrist, and hence putting a Joint Lock on the Wrist and Radioulnar Joint . This can be done by grabbing the opponent's hand with one or both hands, and twisting the hand so that the opponent's thumb points away from the opponent. A supinating wristlock performed from a Stand-up Position , and can be used to force the opponent to the ground on his or her back. Straightening the arm does not alleviate the pressure, since the Shoulder Joint does not allow further supination of the hand. .]] Pronating wristlock The pronating wristlock (in Budo referred to as ''kote mawashi'', 小手回し, "wrist turn") is similar to the supinating wristlock except that it is reversed in direction, known as 'internally rotating' the wrist. The hand becomes maximally pronated, resulting in a Joint Lock on the Wrist and Radioulnar Joint . The degree of possible pronation depends on the degree of flexion at the Elbow , as a bent elbow inhibits rotation of the Humerus . Hence, straightening the arm allows rotation of the whole arm and alleviates the pressure on the Joint s. The arm has to be additionally twisted until the Shoulder Joint reaches maximal rotation to preserve the Joint Lock . This typically results in the arm moving Posteriorly , and allows for the complementary technique of pushing the arm at the Elbow or Shoulder to force the opponent to the ground. HYPERFLEXING WRISTLOCK A hyperflexing wristlock involves forcing the wrist into Hyperflexion by pushing or pulling the hand towards the inside of the Forearm . A hyperflexing wristlock is often performed in combination with rotational wristlocks, since the hyperflexed hand provides a good Lever for twisting, and in addition it increases the overall effectiveness of the wristlock. Hyperflexing wristlocks are often featured as Pain Compliance Techniques , since they allow for good control, and a gradual pain increase if more leverage is added. Hyperflexing wristlocks are also a typical wristlock used as a Submission Hold . .]] ADDUCTIVE WRISTLOCK An adductive wristlock (in Budo referred to as ''kote hono gaeshi'', "partial wrist return") 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. 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-defence technique against Grab bing.
