Neural Exam - Newborn tone - scarf sign

From Embryology
This 5-day-old infant is in the alert, quiet state.
  • The tone of the shoulder girdle is assessed by taking the baby’s hand and pulling the hand to the opposite shoulder like a scarf.
  • The hand should not go past the shoulder and the elbow should not cross the midline of the chest.

Scarf Sign Assessment
This Scarf Sign assessment based upon 1970 study criteria.[1]

With the baby supine, take the infant's hand and try to put it around the neck and as far posteriorly as possible around the opposite shoulder. Assist this maneuver by lifting the elbow across the body. See how far the elbow will go across and grade.

Score
  • 0 - Elbow reaches opposite axillary line
  • 1 - Elbow between midline and opposite axillary line
  • 2 - Elbow reaches midline
  • 3 - Elbow will not reach midline.
