The spine is the pillar of the body and is located in the middle of the back. The normal state of the human spine is “S” shaped in the sagittal plane, as the body’s central skeleton, weight bearing, shock absorption, protection and movement and other functions. A. What is scoliosis? Scoliosis is the bending of the spine in the coronal plane to the left or right away from the midline of the body. The most common classification of scoliosis is idiopathic scoliosis, which accounts for about 70 to 80 percent of all scoliosis. Second, how to prevent adolescent idiopathic scoliosis? Scoliosis should start with prevention. Parents should pay attention to observe the growth of the trunk of infants and children, and regularly take the child to the hospital for examination, early detection, early diagnosis, early treatment, children should pay attention to crawling, sitting, standing, walking and other physical changes, while schools should vigorously strengthen the propaganda of adolescent health work. In the usual heavy study life, parents should remind their children to pay more attention to physical exercise and develop good study and reading habits. The science of physical exercise?1. Life lies in sports. Youth physical exercise has a significant impact on growth and development. The content of physical exercise should be diversified to enhance the strength of the back muscle groups in general. In addition to physical education classes and radio exercises, every day should adhere to at least one hour of other physical exercise. Try to participate in more activities such as single and double bars, jumping boxes, balance beam and other activities to make the back muscles develop symmetrically, which has a good effect on the prevention of spinal curvature. 2, good learning style includes the correct reading and writing posture and the height of the appropriate table and chair. Correct posture means that the body is a fist away from the table, the eyes are a foot away from the book, the body is sitting upright, the book is placed on the right side of the body (suitable for right-handed writing), such habits need to be developed, the bones and body are very good; the correct height of the table and chairs should be able to make a person sit when maintaining two basic vertical, one is when the two feet flat on the ground, the thighs and calves can be basically vertical. Secondly, when the two arms are naturally down, the upper arm and the small arm is basically perpendicular. This will enable one to maintain the correct writing posture. If the height of the desks and chairs are not timely based on height changes and make the appropriate adjustments, so that adolescents sitting improperly for a long time may induce scoliosis. 3, the appropriate weight of the school bag and backpack way. The backpack is too heavy and the wrong way to carry the backpack may cause back injury and muscle fatigue in adolescents. Children in the growth spurt backpack too heavy may cause abnormal development of the spine. At the same time, muscles may become fatigued due to extreme tension, leaving the neck, shoulders and back vulnerable to injury. Therefore, it is recommended to keep the weight of the backpack below 10% of the backpacker’s body weight. It is also important to place the contents of the backpack reasonably, with the heaviest items being placed closest to the back. It is recommended that children carry their backpacks on both shoulders as much as possible. One-shoulder backpacks or crossbody backpacks are always stressed by one side of the body, which inevitably results in a skewed body shape over time. Carrying a backpack over two shoulders can distribute the weight of the backpack, thus reducing the possibility of body distortion. Tighten the backpack straps as much as possible, and always keep the backpack position in the middle of the strongest back muscles when backpacking. These details are often not easy for children to notice, and this is the time when parents need to help their children to adjust the length of the backpack straps properly to make the school bag as comfortable as possible. 4. Reasonable eating habits. Reasonable diet means that the nutrition provided by three meals a day must meet the needs of human growth, development and various physiological and physical activities. Should pay attention to the meat and vegetables, reasonable diet, to provide the nutrition needed for the growth and development of adolescents. In addition, adolescents are the peak of bone growth and development, appropriate increase in calcium intake, can provide the calcium needed for rapid bone growth and development, can also reduce the occurrence of scoliosis.
