Many parents worry that primary and secondary school students carrying too heavy school bags will affect their bone development, experts say, in fact, there is no direct evidence that it will cause harm to students’ bone growth, including shape. What parents need to worry about is whether the child’s spine will occur unexplained scoliosis phenomenon. About 1.06% of Chinese people have scoliosis Some data show that about 1.06% of people in China have scoliosis, which is an alarming percentage. “Less severe scoliosis does not require treatment, and if the curvature of the spine exceeds 20%, then timely treatment is needed. If the curvature is more than 40%, it can only be corrected by surgery.” Experts say that scoliosis differs according to the cause, there are cases of idiopathic scoliosis, congenital scoliosis and neuromuscular scoliosis, of which idiopathic scoliosis is the most common, accounting for 80% of scoliosis. Scoliosis due to trauma is rare, and in fact, after much research, the specific causes of scoliosis are still not well understood. In the case of the most common idiopathic scoliosis, it can be caused by genetic factors, hormonal influences, abnormal connective tissue development, neuro-balance system dysfunction, and neuroendocrine system abnormalities. Therefore, parents need to pay more attention to whether their child has an abnormal curvature of the spine, and if it is detected early, then treatment will be much easier. Bending experiment to check whether the child scoliosis “Because scoliosis does not hurt or itch, so even if the child occurs scoliosis, he or she will not feel it, which requires parents to find out.” Experts say that clinically some children with scoliosis, their parents accidentally find out that their child’s spine is not right when they give them a bath or change their clothes, before they bring them to the hospital for examination. “Can feel it by hand or even can directly see the bend with the naked eye, then the curvature is generally more than 30%, has delayed the best time for treatment, so parents can determine whether the child has spinal problems through a simple bending experiment.” Experts reminded. The specific method of the bending experiment is: parents and children face each other or stand behind the child, the child’s hands straight, both legs stand straight and tight, bending downward. Carefully observe whether both sides of the child’s back is the same flat, such as not flat, scoliosis is very likely, so you can find some very light, early scoliosis. In addition to this experiment, the following details can usually be used to determine whether scoliosis. (1) one hip is higher than the other and the waist is asymmetrical; (2) one shoulder is significantly more prominent or “enlarged” than the other; (3) the neckline is uneven and one shoulder is higher than the other; (4) the girl’s breasts are not equally developed and one side tends to be larger.
