This friend, the clinical manifestations of cerebral palsy: (1) the motor development is backward, and the active movement is reduced: all children with cerebral palsy are backward in different degrees, such as looking up, sitting alone, climbing, standing, walking and other rude sports cars; Grasping things, the fine movements of fingers also lag behind normal children. (2) Decreased active exercise: decreased performance in neonatal period, poor sucking ability and foraging response. At three months, the kicking action of lower limbs is obviously reduced or both legs are kicked at the same time. Hemiplegic cerebral palsy is usually characterized by decreased activity on one side. The limbs of sick children rarely move, especially the lower limbs, which are often characterized by hemiplegia, bilateral paralysis and quadriplegia. Because of the difficulty of voluntary movement, stiff and uncoordinated movements, abnormal movement patterns often appear. Hypotonia is characterized by paralysis, softness and excessive silence. (3) Abnormal muscle tension and posture: Most children with spastic paraplegia gradually increase their muscle tension with age, showing that their lower limbs are straight and adducted, and sometimes they are scissors-shaped. The tension of upper limb flexors increases, and both hands often make fists. Muscle tone of children with hand-foot cerebral palsy is low in infancy, and then it increases. (4) Abnormal reflexes: When a normal 4-month-old child stands upright, if he leans to the left and right, there will be protective reflexes and his head will automatically stay in the middle position; Tilting for about 5~6 months can straighten the upper limbs and maintain balance; At the age of 9 months, when the child is in prone position and suspended, the child's "parachute-like reflex" is normal, that is, the upper limbs stretch forward, and these protective reflexes and balance maintenance abilities of children with cerebral palsy weaken or disappear.
