There are few things more exciting to a Pittsburgh couple than the prospect of having a child. While the focus is on all the positive things that can come with a new arrival, there are always potential risks that can come up when a child is born. One such danger is if the child is injured during birth and is found to have Erb's palsy. Erb's palsy can occur when the nerves close to the neck -- known as the brachial plexus -- are affected. They assist with moving and feeling sensation in the shoulder and all the way through to the fingers. If there is weakness, it is known as palsy.
