During summer vacation, many parents choose to send their children to dance training classes. However, what is rarely known is that a common lower back movement in dance training may lead to injuries or even paralysis in children. Significant changes in posture can easily cause spinal cord injury. "In the past three weeks alone, we have treated 5 cases of 'lower back paralysis'," Liu Zhen, deputy chief physician of spinal surgery at Nanjing Gulou Hospital, said in an interview with the media. Among them, an 11 year old girl developed paralysis while dancing down at the age of 5. This child immediately developed paralysis, with spinal deformities and pelvic tilt gradually occurring over the next six years, "Liu Zhen said. For children, the treatment of" lower back paralysis "is a world challenge. A 10 year old girl from Wuhan, Qingqing, also suffered from high paraplegia due to an injury caused by performing a lower back movement during dance training. Guo Xiaodong, a treatment doctor from Qingqing and a professor of orthopedics at the Affiliated Union Hospital of Tongji Medical College of Huazhong University of Science and Technology, said that children with "lower back paralysis" may experience various complications such as scoliosis, severe osteoporosis, repeated urinary system infections, bedsores, and psychological disorders. Why can a common dance movement cause such serious consequences as paralysis? Liu Zhen introduced that when practicing lower back, the spinal cord is correspondingly stretched. Children have strong spinal flexibility and can reposition themselves after relative displacement of the spine, but the spinal cord often finds it difficult to adapt to excessive stretching of the body position. Therefore, significant changes in body position can easily cause spinal cord injury. A recent data released by Guo Xiaodong's team shows that since 2005, more than 1000 children in China have been paralyzed due to lower back movements. Dance lower back training has become a major cause of spinal cord injury in children in China. According to relevant data, from 1992 to 2002, only 4.0% of all children with spinal cord injury were affected by dance lower back training. From 2015 to 2019, this proportion had reached 33.9%, and in non fracture dislocation spinal cord injury, it accounted for 64.1%, showing an overall upward trend year by year. On July 21st, the Ministry of Education and the China Consumers' Association jointly issued a document titled "Don't blindly participate in training, let children have a healthy and happy summer vacation", which clearly stated that for non disciplinary training that meets children's interests and strengths, it is necessary to arrange training time reasonably, and carefully select compliant institutions. At the same time, parents are particularly reminded to pay high attention to the risk of injury or even paralysis caused by children's dancing, bending, and other movements. Several interviewed experts have stated that children should practice dance movements under the guidance of professionals and are not recommended to learn or train dance on their own. If you want to participate in lower back training, parents should first take your child for a physical examination. Children with congenital spinal abnormalities such as spina bifida or tethered cord syndrome should not learn dance. At the same time, children should fully warm up before practicing movements, and then slowly perform spinal extension and other movements. In addition, once a child experiences discomfort after lowering their waist, they should seize the golden rescue time to minimize spinal cord injury as much as possible. Guo Xiaodong told reporters that the golden treatment time for spinal cord injury is within 8 hours. Liu Zhen said, "If some children with 'lower back paralysis' could have been treated well at that time, they might not have caused
