* Arm traction is done with the baby in the supine position.
* Arm recoil tests tone and action of the biceps.
* The wrist is grasped and the arm is pulled until the shoulder is slightly off the mat.
* The arms are held in flexion against the chest for a few seconds, then are quickly extended and released.
* There should be some flexion maintained at the elbow.
* The arms should spring back to the flexed position.
* Full extension at the elbow is seen in hypotonia.
* 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.
