Neural Exam - Newborn reflexes - grasp

From Embryology
Newborn n 26.jpg
This 5-day-old infant is in the alert, quiet state.
  • Placement of the examiner’s finger in the palm of the hand or on the sole of the foot will cause flexion and grasping of the fingers or toes.
  • One should avoid touching the dorsum of the hand while eliciting the grasp reflex because stimulating the back of the hand causes a hand opening reflex to occur.
  • With the two competing reflexes, the grasp response will be incomplete or inconsistent.
  • You can actually see this happen with the baby that is being examined.
  • The grasp reflex can be reinforced by applying traction on the arm.
