Neural Exam - Newborn tone - arm recoil

From Embryology
Newborn n 06.jpg
This 5-day-old infant is in the alert, quiet state.
  • Arm recoil tests tone and action of the biceps.
  • The arms are held in flexion against the chest for a few seconds, then are quickly extended and released.
  • The arms should spring back to the flexed position.
  • The hyotonic infant will have slow incomplete recoil.
  • Asymmetry to this response with lack of recoil would be seen with Erb’s or brachial plexus palsy.
