Pediatric cerebral palsy is a syndrome characterized by postural abnormalities and motor deficits caused by damage to the immature brain tissue before birth, at birth, and during the first month of life, resulting in a non-progressive, irreversible lesion. It can be accompanied by neurodevelopmental delay, epilepsy, visual and auditory abnormalities and feeding dysfunction. 1.Little boldness Mainly refers to spastic cerebral palsy. Due to the high excitation of upper motor neurons, the child appears to have little boldness in the clinic, which shows that the child is quite nervous at the slightest sound and the whole body is nervous at the slightest stimulation. (1) Because the child is timid, he or she always feels dependent on objects to feel safe; (2) Because parents are afraid of frightening the child, they often hold him or her since childhood and are too spoiled, so the child slowly develops a sense of dependence. (3) Less sleep Because of the excitement of the upper motor neurons, the child generally sleeps less, especially in the first few months after birth, and the sleep time is short. Because the heavier the spasticity, the less sleep, so make sure the child has enough sleep so that the spasticity is relieved and the body will be strengthened. (1) Pregnancy, perinatal high-risk factors and specific symptoms Those with clear high-risk factors can be diagnosed, but in some cases it is difficult to be sure even after detailed medical history, and newborns and infants within 3 months of age should be alerted if they have difficulty sucking, poor feeding response, are too quiet or particularly irritable, and cry incessantly. (2) Abnormal muscle tone and posture ① Obvious asymmetry in body position and movement of the left and right limbs. ②The hands cannot be held in front of the eyes (in the direction of the center) and played with in the supine position, and the hands are clenched into fists (thumbs clenched in the palms). ③The head is still tilted back or the head droops when pulling up from the supine position to the sitting position due to low muscle tone in the neck. ④ When sitting position, the back is obviously arched, reluctant to stretch the legs to sit, when holding the armpit in the upright position, the feet do not kick and stir, the muscle tone of the lower limbs is increased, the lower limbs are straight, inward, pointed feet, and scissor-like. (3) Motor development is backward, the child often can’t stand up the neck, can’t turn over, can’t sit or crawl independently, etc. (4) Abnormal reflexes often manifest as delayed disappearance of primary reflexes and non-appearance of protective reflexes. Particular attention should be paid to the tense vagus reflex, asymmetrical tense neck reflex and standing support reflex, which are three primitive reflexes that often disappear with great difficulty in children with cerebral palsy. At 4-5 months of age, if the torso is tilted to one side in the standing or sitting position, the infant can adjust the head so that it remains in a neutral position as much as possible, or the upper limbs can be extended for protection. The above reflexes do not appear in children with cerebral palsy at this age.
