A Primer on Erb's Palsy for the Lay Person
Often, the newborn's inability to use the effected arm is recognized immediately or shortly after birth. Sometimes it is detected in the newborn nursery. Following a difficult delivery in particular, the possibility of a nerve injury should always be considered and ruled out. The baby's pediatrician can order a pediatric neurology consultation, a MRI of the shoulder, and/or electrical studies (called EMG's, or nerve conduction or nerve velocity studies), to identify and locate the point(s) of injury to the nerves.
