This is some knowledge about orthodontics, I hope it will be helpful to you~ Orthopedics includes the correction of "X" and "0" shaped legs and the correction of hunchback. 1. Correction of "X" and "O" shaped legs: Toned, slender and well-proportioned legs are an important symbol of human body beauty. "X" and "O" shaped legs are tabooed by people because they seriously affect the beauty of the body. If you want to make your legs grow normally, you just need to master the method of measuring your legs. Take a standing position with your feet as close together as possible and your legs straight and close together. Then use an ordinary compass to measure the distance between the medial malleolus and the inside of the knees. If the distance is within 1.5 cm, it is normal; if the distance between the two inner knees reaches 2.5 cm, it is a moderate "O"-shaped leg; if it is more than 3.5 cm, it is a severe "O" shape. Shaped legs; if the distance between the two medial malleolus reaches 2. 5 cm, it is a moderate "X"-shaped leg, and if it exceeds 3.5 cm, it is a severe "X"-shaped leg. For the correction of these two kinds of deformed legs, the younger you are, the better the effect will be, and the effect will be worse after you are over 30 years old. Several correction methods are introduced below. ①Correction method of wearing corrective shoes: Wear special corrective shoes. The soles of these orthotic shoes are thicker on the outside for "O"-shaped legs, and thicker on the inside of each sole for "X"-shaped legs. Depending on the degree of individual leg deformity, the thickness of the inner and outer soles should also be different. However, when you first wear corrective shoes, the thickness can be slightly smaller, and then gradually increase the thickness according to the correction requirements. When standing or walking in corrective shoes, the entire sole of the foot must be in contact with the sole, and the torso and legs must be kept as straight as possible. In addition, avoid carrying heavy objects for long periods of time. This method is simple and easy to implement and has good results. You should usually wear corrective shoes for about a year. If you cannot buy corrective shoes in the market, you can also make your own. ② Try to change the bad foot shape when walking: Generally speaking, people with "X"-shaped legs mostly walk in an "eight-shaped" shape from the outside, and people with "O"-shaped legs mostly walk in an "eight-shaped" shape from the inside, so combined with the space Orthopedic shoes should try to change the bad foot shape when walking. ③Corrective gymnastics The specific method of corrective gymnastics for "O"-shaped legs is: Hold an object between the knees, squat down and then stand up, keeping the protruding object from falling. Repeat 9 times (1 group), and finally do 7-9 groups. Stand with your legs apart, with your feet parallel and slightly wider than your shoulders. After a half-squat, buckle your knees inward and press your calves inward from both sides with both hands. Hold for 6 to 9 seconds, then stand up and relax. Repeat 9 times. Kick the calf flat to the outside, like kicking a blanket with the outside of the foot, once on each side, kick the calf as flat as possible, and kick 81 times in a row. It would be better if you can kick a shuttlecock or a small sandbag. The specific method of "X"-shaped leg correction gymnastics is to sit on a chair, support your arms back, clamp a soft object at the ankle, and place the heel on the ground. Clamp the soft object and use the heel to bring the leg as far forward as possible to keep the soft object from falling off. Drop, pause for 4 to 5 seconds, then return to relaxation. Do 9 times in a row (1 group), and finally do 3 groups. The object to be clamped should be thicker first and then gradually become thinner. Sit on the bed, bend your knees, place the soles of your feet facing each other, place your hands on the inside of your knees, and then press down as much as possible. The movements should be gentle and powerful, and relax after 4 to 5 seconds. Repeat 9 times (1 group), 3 groups. Kick the two calves inward alternately, like kicking a shuttlecock. Try to kick the calves as flat as possible. Kick 81 times in a row. If you can kick a shuttlecock or a small sandbag, the effect will be better. Things to note when doing orthopedic aerobics: First, you should pay attention to exercising step by step, insisting on doing it once in the morning and once in the evening, and gradually increase the intensity and depth of the movements, and lengthen the exercise time. During the exercise, you must maintain correct postures of sitting, standing, and Walking posture. As long as you keep exercising, you will see results in 3 months. The second is to take care of your body and avoid violent, forced and sudden movements when doing corrective exercises to avoid undue harm. Third, it should be noted that in addition to the above-mentioned corrective gymnastics, strength exercises to strengthen the muscles of the legs and trunk should also be added to increase the correction effect. 2. Correction of hunchback: Some middle school and high school students have spinal abnormalities, which are more common in hunchback or small hunchback. In class, she leans on the table and lowers her head when walking. Especially the tall male students always bend over. The female students are too shy during their development period and hold their breasts, which gradually forms a hunchback. Hunchback is very harmful to physical development. First, it affects normal physiological functions, causing compression of internal organs in the chest, affecting breathing and blood circulation, and thus affecting the development of the entire body. Secondly, hunched back also makes the posture unattractive. To prevent and treat hunchback, the first step is to develop correct postures for sitting, standing and walking. The chest should be held high, the head raised, the shoulders stretched back and drooped naturally, and the body should not be crooked or slanted.
In addition, physical exercise should be strengthened and the content of exercise should be diversified. For students who have abnormal spinal curvature, corrective exercises should be performed to develop good habits. Here is a simple and easy way to treat small hunchbacks: force yourself to lie on your back when sleeping, sleep on a hard bed, and keep the pillow low when sleeping on your back. You may feel a little uncomfortable at first, not sleeping well, or waking up tired and with soreness in your lower back. This is the sign that it is starting to take effect. If the pain is unbearable, you can raise the pillow a little higher or lie on your side for a while, but stick to sleeping on your back. This requires perseverance, and you will feel comfortable with it after a dozen days. Then you can remove the pillow and sleep directly on your back on a flat bed. After sleeping like this for a few months, you will see results. Sleeping on your back for a long time can consolidate the correction results. A person's sleeping time accounts for about 1/3 of the whole day. Keeping the spine flat during this period of time and fixing the spinal bones and muscles in the correct posture will inevitably correct spinal abnormalities naturally. In addition, for the treatment of scoliosis, it is better to do corrective gymnastics. The specific methods are as follows. ① Stand with your feet wide apart, straighten your legs, let one arm droop naturally, and raise the other arm sideways to do side flexion. Note that the amplitude should gradually increase, and the upper body should not lean forward or backward. ② Stand with your feet wide apart, straighten your legs, put one hand on your waist, raise one arm to the side, and perform lateral flexion to the side of your waist. Note that the amplitude should gradually increase, and the upper body should not lean forward or backward. You can also place one hand on your hips and the other on your head, do lateral flexion to the side of your hips, and push with both hands at the same time. Follow-up question: hao It’s so difficult. And it’s not a short term either.
