Definition

Erb’s palsy happens when a baby’s neck is stretched during labor and delivery. This can cause damage to the upper nerves of the neck and shoulder. The nerve damage can then cause certain muscles in the baby’s arm to be weak. Over time, the baby can recover movement. Feeling in the arm can also be recovered. In some cases, long-lasting damage can occur.
