Pediatric cerebral palsy is a syndrome of various motor dysfunctions caused by non-progressive brain injury during the first month of life. It is a common syndrome of central nervous system disorder in pediatrics, with lesions in the brain and involving the limbs, often accompanied by symptoms of mental retardation, epilepsy, behavioral abnormalities, mental disorders, and visual, auditory, and language disorders. 1. Backward motor development and reduced active movement: Children with cerebral palsy show reduced movement, low sucking ability and low feeding response in the neonatal period; the development of gross and fine movements is backward to varying degrees compared with children of the same age, and even cannot walk for life. 2, muscle tone abnormalities: varies according to different clinical types, spastic type shows increased muscle tone, hypotonia type shows limb flaccidity, but tendon reflexes can still be elicited, involuntary movement type shows variability muscle tone incomplete. 3. Postural abnormalities: In infancy, children with cerebral palsy often have flexion of the limbs and hips above the head in prone position, sometimes the shoulders are on the bed and the hips are elevated; in supine position, the head is tilted back, the lower limbs are straightened, and even the coracoid arch is inverted, and in the case of hypotonia of the limbs, the body is in the shape of a supine frog; when rolling, the body is like a roller; in supine traction, the head is tilted back, the lower limbs are straightened, and the feet are plantar flexed, and they are often pulled up directly without sitting; when standing up, the two lower limbs are crossed and the toes of the feet are on the ground; the hands are held and the toes of the feet are on the ground. The two lower limbs are crossed and the toes of the feet are on the ground when standing; the hands can be seen clenched or the palms of the hands are turned outward to take things. Reflex abnormalities: (1) Delayed disappearance of primitive reflexes: e.g. crossed leg extension reflex after 2 months, grip reflex after 2-3 months, asymmetrical neck tension reflex after 4-5 months, hug reflex after 6 months; (2) Weak or delayed appearance of protective reflexes: e.g. unable to hold the head upright when standing upright after 1 month, unable to keep the head in a neutral position when tilting the torso from side to side after 4 months, unable to keep the head in a neutral position when tilting the torso suddenly in a sitting position after 4-5 months. When the body is suddenly tilted in the sitting position, the upper limbs do not extend to support the body, and the “parachute reflex” is not induced at 8-9 months of age. Other early manifestations: (1) easily irritated, continuous crying or excessively quiet, weak cry, difficulty in nursing and swallowing, easy to vomit, poor weight gain; (2) abnormal sensitivity and agitation to sound and position change, difficulty in falling asleep or unresponsiveness, unrecognizable and unable to cry; (3) difficulty in nursing, their fists are not easy to break, thighs are not easy to abduct, feet are easy to dorsiflex stiffness, etc. 6, concomitant diseases: may be combined with language or mental retardation, epilepsy, audio-visual impairment, cognitive behavior abnormalities, etc.
