According to statistics, there are about 2.7 children with cerebral palsy in every 1000 children in China. These children often have abnormal postures such as clenched fists, head tilted back, tense and stiff limbs, walking on the tips of the toes, and scissor stance. If they are not detected early due to inattentive parents or physicians who do not know the disease. Detection and treatment can result in lifelong physical disability. The best time to treat brain injury is within the child’s first year, but unfortunately, many children are delayed. There are several reasons for this: 1, do not believe that their child has a disease: many parents are reluctant to believe that their child has a disease because of the lack of knowledge of childcare, and often miss the best recovery period when they come to the clinic. Therefore, parents should know the normal child’s motor and postural development age, such as 3 months can erect the child’s head stable, about 4 months can roll over, 5 months can actively reach out to grasp things, 6-7 months can sit alone, 8 months will crawl, etc.. Parents can compare their children with their neighbors’ children and regularly consult a pediatrician to evaluate their children’s motor and postural development. 2. Misdiagnosis as “calcium deficiency”: It is the most common misdiagnosis of cerebral palsy as calcium deficiency. Children with brain injury often have impaired calcium and phosphorus metabolism, combined with motor dysfunction resulting in limited activity and little outdoor activity, so it is very common for cerebral palsy to be combined with “calcium deficiency”. If the child is simply calcium deficient, the performance should be excessive sweating, easy to panic, posterior occipital baldness, rib edge ectropion, etc., there should be no muscle tension, stiff limbs inflexible and abnormal posture, etc. 3. Paralysis and carelessness: fluke waiting For example, if a child does not come to the hospital because of a soft neck and head lifting, the physician clearly tells his parents that Kang Kang has high risk factors such as prematurity, twin births, low birth weight, etc., and with the current performance, it is likely to be cerebral palsy and should be treated urgently. The parents thought that the child was born prematurely, so he should be weaker and develop later than other children, and that they should wait until he grew up. As a result, the best time for treatment was missed. Now, even if the child can recover, the treatment will take longer and be more difficult, and may leave sequelae. There are many parents of children with this kind of fluke mentality. In fact, as long as there are high-risk factors such as prematurity, low birth weight, jaundice, obstructed labor, asphyxia, etc., and the motor development is backward along with neurological developmental abnormalities such as head tilting back, fist clenching, limb stiffness, etc., it may generally be judged as brain injury.
