PediNeuroLogic Exam: Newborn: Normal: Tone - Arm Recoil (x2)
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 hypotonic infant will have slow incomplete recoil. Asymmetry to this response with lack of recoil would be seen with Erb's or brachial plexus palsy. PediNeuroLogic Exam has been supported by a grant from the Slice of Life Development Fund at the University of Utah, the Department of Pediatrics and the Office of Education at the University of Nebraska Medical Center. Viewing the videos requires installation of the free QuickTime Plug-in.
