The importance of early detection and early treatment: In infantile cerebral palsy, some scholars believe that there is no defect in the developmental process of the central nervous system per se. If thorough and systematic physiotherapy is implemented at an early stage, the brain’s own maturation capacity can be promoted, and the so-called plasticity can be expected to compensate for the functional substitution of the organic brain damage. It is very difficult to treat contractures, deformations and secondary disorders of the muscular one-bone pathway system when they are formed. It is generally considered to be able to be diagnosed within 6 months of age, which is called early diagnosis, and cerebral palsy diagnosed within 1 year of age, which can also be called early diagnosis. The significance of early diagnosis is mainly to enable early correction of the limb movement disorder of the child. The brain is in a rapid growth and development stage during the first 6 months of life, and the brain injury is also in the primary stage, so the abnormal posture and movement are not yet fixed, and the movement disorder can be easily recovered after treatment. Early diagnosis is mainly based on medical history and clinical manifestations, with emphasis on the following points: 1, whether there are abnormal factors in the perinatal and neonatal periods, such as intrauterine hypoxia, intrauterine infection, prematurity, asphyxia, etc.; 2, whether the motor development is backward, such as lifting the head, grasping objects, sitting, crawling, standing, walking, etc., which is obviously behind normal children; 3, whether there are abnormal reflexes, mainly the delayed disappearance of primitive reflexes, late appearance of physiological reflexes and pathological 4. abnormal posture and muscle tone, such as obvious asymmetry of left and right limb position and movement, stiff and straight limbs, head tilted back, or weakness, etc. The diagnosis of pediatric cerebral palsy should be made by a professional physician because of its complicated manifestations and easy misdiagnosis.
