Cerebral infarction in newborn babies is more serious, the infarcted area will be necrotic and form soft foci due to ischemia, and the critical area will cause hemiplegia and even unfavorable language development. Therefore, it is important to observe the movement of the baby’s limbs at an early stage, for example, if the baby prefers to use one side of the hand when teasing with toys, or if there is asymmetry in the upper limbs of both limbs, then hemiplegia may occur, and comprehensive rehabilitation therapy is needed at an early stage. The younger the age, the better the effect of rehabilitation treatment. If the treatment is late, the dominance of one side of the limbs has already been formed, and it is difficult to be willing to apply the upper limbs and lower limbs of the hemiplegic side, which will result in the formation of severe hemiplegia affecting the motor function in the future.
