The hugging reflex is a sudden change in the newborn’s posture or when he hears a loud sound, he will have his arms outstretched and fingers extended; his upper limbs are flexed and tucked in a hugging position; sometimes accompanied by crying. Hyperreflexia is indicative of bilateral brain disease, and its disappearance or diminution in the neonatal period suggests a state of central nervous system depression in the newborn. So how is the initial clinical diagnosis of the disease? If a newborn baby is lying flat on his back and you put your finger in his little hand, he will immediately hold it firmly. At this point the baby can be easily pulled up so that the upper half of his body is off the bed. Pull the finger out of the baby’s palm and the baby will fall on his back. At this point, the baby will stretch his limbs dramatically and then immediately retract them again, with his little arms clasped tightly to his chest and his little legs curled up, and he will cry. This posture is like self-protection, but also like in the cry for help. Suddenly grab the baby’s feet, or suddenly make a loud noise, the baby will also appear this reflex.
