Pediatric cerebral palsy is a syndrome of non-progressive brain damage caused by various reasons before birth to one month after birth. The causes of cerebral palsy are complex and varied, mainly focusing on three aspects: first, prenatal factors, including intrauterine infection, intrauterine growth retardation, trauma during pregnancy, multiple pregnancies, etc.; second, intrapartum factors, mainly prematurity and obstructed labor; third, postpartum factors, including hyperbilirubinemia, blood loss, neonatal shock due to infection, cranial injury and epileptic convulsions, and genetic factors. Among these factors, prematurity and low birth weight are the most important factors causing cerebral palsy, and the shorter the gestation period and the lower the birth weight, the higher the prevalence of cerebral palsy. The early symptoms of cerebral palsy are very obvious, and parents can detect the signs of cerebral palsy if they look carefully. In the neonatal period, the child shows no interest in everything around him or her, is very unresponsive, has fewer movements, and has poor sucking ability, often choking on milk. If a doctor examines the child, he or she may find that some innate reflexes, such as the feeding reflex, holding reflex, and hugging reflex, are diminished or do not appear at all. In infancy, the child shows signs of delayed intellectual-motor development, such as difficulty in thigh abduction, knee flexion and difficulty in straightening, straightening and inward movement of the legs when held upright, crossed legs in a scissors shape, flexion of the elbow and wrist joints of the upper limbs, and frequent clenching of the hands with the thumbs inward. After 5 months of age, the baby is still unable to reach out and grasp the things he likes, or always uses one hand to grasp. Abnormal reflexes, i.e., delayed disappearance of some primitive reflexes and weakened or absent normal protective reflexes, may also appear some pathological reflexes. Children in early childhood already have many behavioral abilities, and any abnormalities are easily detected. The child may have physical movement disorders, such as inability to walk or abnormal walking posture, such as toe landing, scissor gait, limp, inability to squat, etc., inflexible hand movements, inability to fetch things with the hand or always use one hand to get things, mental retardation, language development or language disorders, or abnormal vision, hearing loss, etc. Cognitive and behavioral abnormalities, such as excitement and hyperactivity or isolation and vulnerability, may occur. Some children with cerebral palsy may have tardive dyskinesia, ataxia, hypotonia, ankylosis, tremor, etc. Once a child is found to have cerebral palsy, early intervention in rehabilitation is of great significance to the prognosis.
