Bodyguard technical and tactical joint control lock

Bodyguard technology and tactics joint control lock control lock technology, which applies the lever principle in physics to exert pressure on the attacker's joints, so that the attacker's joints are in the range of abnormal physiological activities and subject the whole body to severe joint pain. The joint is the junction of bone and bone. It realizes all the movements of human function under the control of the nervous system through the muscles and ligaments attached to the joints. The body structure and activity specification of any joint can not be changed. If the body structure violates the physiological characteristics, the concave and convex sides of the joint will separate from each other, resulting in whitening, pain, loss of activity, inevitable distortion of tendons, and unable to continue to maintain physiological functions. These injuries can also cause damage to human nerves, meridians, blood circulation and muscles. The main targets of lock control technology are shoulder joint, elbow joint, finger joint, wrist joint and so on. The stability of shoulder joint is poor and easy to fall off. Twisting to the left and right, pulling back to the extreme, or hitting with pressure will cause shoulder dislocation and tear ligaments and muscles. The most commonly used technology of shoulder joint lock control technology is the single arm shoulder buckle lock. The single arm shoulder buckle lock can also be called turning the arm and folding the elbow. It is to grasp the attacker's arm first and then turn it back. If he tries to break free, you can rotate his shoulder card by raising his wrist, so as to produce great tension on the tendons and joints. This technique is more commonly used when raising suspect. The range of motion of the elbow joint is relatively small. When the elbow joint is completely straightened, when the pressure is applied from the rear side or the elbow joint is twisted to the rear left and right, it will cause joint whitening, ligament muscle tear or olecranon fracture, and the function of the forearm and hand will be lost. When approaching the attacker, quickly grasp the attacker's wrist, then quickly grasp the elbow joint of the captured wrist with the other hand, and then pull the elbow in the opposite direction of the pushing wrist to make the elbow form an "s" shape. At this time, if you suddenly use violence, you can cause the attacker's elbow to whiten. Although the range of motion of the wrist joint is large, it is very weak. If the wrist is forced to transition to any direction, pulling and twisting can damage the bone and ligament of the wrist, dislocation of the joint, tearing of ligaments and tendons, or even fracture. When controlling the wrist lock joint, first of all, ensure that your opponent's elbow and wrist are at a 90 "angle, which requires you to grasp quickly after contacting the attacker. Then form a" C "shape in his forearm, commonly known as C lock. The advantage of this method is that no matter how strong the attacker is, it is difficult for him to break free as long as you form C lock at his wrist.
