Neural Abnormal Exam - Newborn tone - scarf sign

From Embryology
Newborn ab 07.jpg
This is a 3 weeks old infant.
  • The scarf maneuver demonstrates low shoulder girdle tone.
  • The hand actually can be pulled beyond the opposite shoulder and the elbow goes past the midline.

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.
