summary
Plantar reflex extension is a symptom caused by cerebral palsy. More common in infants. Most of the children's plantar reflexes showed extensional reaction, which was only the initial clinical manifestation. What is the definition of plantar reflexivity?

Diagnosis: at present, there is no specific diagnostic index for cerebral palsy, which is mainly based on clinical symptoms and signs. The three diagnostic criteria of cerebral palsy in children in China (1988) were as follows: ① central palsy in infancy; ② With mental retardation, convulsion, abnormal behavior, perception and other abnormalities; ③ Except for central palsy caused by progressive diseases and transient motor retardation of normal children. The possibility of cerebral palsy should be highly vigilant in the following cases: ① premature infants, low birth weight infants, severe hypoxia at birth and neonatal period, convulsions, intracranial hemorrhage and bilirubin encephalopathy, etc; ② Mental retardation, emotional instability and panic, motor retardation; ③ There were typical manifestations of hypertonia and spasm in limbs and trunk; ④ Extrapyramidal symptoms with bilateral deafness and hyperopia paralysis.
Prenatal factors congenital brain dysplasia, often because the mother gave birth to rubella and other viral infections during pregnancy, especially in the first three months of pregnancy. It is often accompanied by other congenital abnormalities, such as cataract, deafness, congenital heart disease, etc. Fetal erythroblastosis, which causes severe neonatal jaundice, can cause damage to the basal ganglia of the brain, resulting in nuclear jaundice. Pregnancy poisoning can cause intracerebral or subdural hemorrhage in fetus. The serious decrease of blood pressure in pregnant women can cause fetal cerebral thrombosis; Maternal syncope, barbiturate overdose, hemorrhagic shock, trauma or burn can cause fetal brain damage; Malnutrition can also affect fetal brain development. Generally speaking, cerebral palsy caused by congenital factors is mostly bilateral symmetry.
Acute disseminated myelitis usually occurs in young adults. Most of them have symptoms of upper respiratory tract infection or vaccination history a few days or 1-2 weeks before the disease. Cold, overwork, trauma and so on are often predisposing factors. The first symptom was numbness and weakness of both lower limbs, pain in the corresponding part of the lesion, and a sense of band in the lesion segment, which often reached the peak within 2-3 days. Clinically, limb paralysis, sensory loss and sphincter dysfunction are the main characteristics. In the acute stage, spinal cord shock may occur. Below the damage level, there are more autonomic nervous disorders. The disease can enter the recovery period after 3-4 weeks, and most of them basically recover after 3-6 months. A few cases have sequelae of different degrees, but most of them are not accompanied by spastic paralysis, involuntary movement, intellectual impairment and epilepsy.
matters needing attention
Prognosis: the clinical manifestations of cerebral palsy are different, the severity of the disease is different, severe cases appear symptoms a few days after birth, most of the cases were found when the family tried to help up a few months after birth. If the severe bilirubin encephalopathy is not treated in time, most cases can die within a few days to two weeks. Even if the children survive, they often leave behind mental retardation, deafness and low muscle tone; The average survival age of children with paraventricular leukomalacia was 8.5 years; Most of the children with mild postpartum brain syndrome can return to normal or only have mild sequelae and survive for life.
