Neurologic Examination and Newborn Reflexes

The neurologic examination of the newborn begins with the general appearance of the infant. The newborn should have a strong cry and exhibit symmetric movements; a high-pitched or weak cry can be associated with current illness or neurologic deficits. Asymmetric movements can indicate musculoskeletal or focal neurologic injury. Complete absence or asymmetry of any newborn reflex can indicate neurologic deficit or injury. The following developmental reflexes are present at birth in the normal newborn (Thureen et al., 2005): Rooting reflex: When the cheek is stroked, the infant turns the head toward the stimulus and opens the mouth as if preparing to feed.

Sucking reflex: Stroking the lips causes the infant to open the mouth and begin to make sucking movements. The strength and coordination of suck can be assessed using a gloved finger placed in the mouth.

Moro reflex (or startle reflex): The infant's head is raised several centimeters above the examination table while supporting the head and neck. The head is allowed to drop a short distance into the examiner's other hand, and the infant responds by abduction and extension of the arms and opening of the hands. The infant then flexes arms and closes the fists and brings them back in toward the body. Tonic neck reflex: With the infant lying supine, the head is turned to one side. The infant's arm on the side where the face is directed extends, and the opposite arm flexes.

Palmar and plantar grasp: Stroking the palm of the hand causes the infant to grip the examining finger. This grip tightens as the examiner pulls away. When firm pressure is placed on the plantar surface of the foot, the toes curl in toward the examining thumb.

Stepping reflex: The infant is held with both feet touching the examination table. The infant should exhibit alternating stepping movements.

Truncal incurvation (Galant reflex): The infant is held in the prone position above the examination table. Stroking one side of the spine with a finger or cotton swab should cause the infant to flex the pelvis toward the side of the reflex.
