Zhang Chengyu's knee pain always makes people tremble. When walking, they feel like walking on thin ice, and it is easy for them to become more and more unwilling to walk, which makes the leg muscles lose training and reduce muscle strength, thus aggravating the joint burden and forming a vicious circle. In order to avoid this situation, the director of the Japanese osteopathic hospital pushed a trick to hold down the wrist to help the brain issue instructions to relax muscles, and may even improve the problem of knee stiffness and pain. Pressing the wrist can help the brain release a "relaxation" signal to the muscles. Guan Kou Zhixing, president of Tsukuba Plastic Surgery Hospital in Japan, said that almost everyone with poor knees has the problem of stiff hip joints, which leads to the tightening of quadriceps femoris on the front side of the thigh and compression to the knee joint, which makes the knee unable to move smoothly and causes pain. Walking by holding the wrist can relax the stiff hip joint and quadriceps femoris, restore the good mobility of the knee joint and improve the pain of the knee joint. Hands don't seem to have anything to do with knees. In fact, in the eyes of western medicine, the hand is the "second brain", and the wrist can help the hand to establish contact with the brain. Nagata Xiazai, director of plastic surgery at Nagata, a Japanese pastoral cloth dealer, also said that the hand even has the name of "external brain" in the eyes of western medicine. Different from animals, there are many close connections between human hands and brain, such as grasping hands when nervous and excited; On the other hand, if hand tension can be eliminated, it may in turn help the brain relax. Guankou Zhixing also said that due to the incorrect posture, long-term use of mobile phones is easy to dislocate the bones at the wrist, which will oppress blood vessels and nerves, thus affecting overall health. Pressing the wrist can solve the problem of dislocation of the wrist bone, restore the bone to its proper position, and hopefully make the compression of blood vessels and nerves disappear. In addition, the signal of "the oppression disappears" will also be transmitted to the brain, which in turn will prompt the brain to issue "relaxation" instructions to the stiff joints of the whole body. At this time, if we combine striding to move the hip joint and tell the brain that "the part that needs to be relaxed is the hip joint", we can relax the hip joint, eliminate the oppression of the quadriceps femoris, restore the mobility, and then solve the problems of poor knee joint movement, stiffness and pain. Fold the wrist gently on the same side as the painful knee, and press the wrist fold with the help of the thumb of the other hand. If both knees hurt, hold down both wrists in turn to practice. Hold hands completely relaxed, feet raised and knees bent at the same time. Keep this state for a minute, or stay where you are. At the same time, pay attention to raising your knees as high as possible and practice several times a day. If you can't stand, you can stride in the chair. Guankou Zhixing once treated an 80-year-old X-leg patient, Ms. A, and the problem of knee pain continued to deteriorate with age. As soon as I walk, my knee hurts and I have to go to the hospital for an analgesic injection. However, under the guidance of Guan Zhixing, the pain was relieved after taking 100 steps in this way. Now he does it at home by himself every day, instead of going to the hospital for an analgesic injection. There is also a 70-year-old woman who had surgery on her knees because of degenerative arthritis, but her knees still hurt after surgery. However, after about 1 month, this method gradually improved through Guankou Zhixing. Guankou Zhixing also revealed that some patients even went to his treatment hospital with crutches and forgot to take them with them when they left. This shows that this method can help quickly eliminate the problem of knee pain!
