Cerebral Palsy—One birth injury which causes damage to muscle tone, movement, and motor skills is cerebral palsy. Brain damage, occurring during birth, can lead to cerebral palsy, which is a relatively common congenital disorder. Erb’s Palsy--Erb’s palsy is a form of brachial plexus palsy; the brachial plexus is a network of nerves in the neck area that provides movement and feeling to the fingers, hands, and arms. When the upper nerves are affected, the result is Erb’s palsy. Erb’s palsy is most likely to occur in deliveries with a long labor, a very large baby, or a breech presentation. Brachial Palsy—The Brachial Plexus nerves provide electrical impulses to the arm muscles. A diagnosis of Brachial Palsy means the baby suffered an injury to the Brachial nerves; the severity of the birth injury will depend on whether the injury was a total tear, a partial tear, or a stretch—as well as where the injury occurred.
