What is Erb’s Palsy?
Erb’s palsy is a condition that is caused by an injury to the brachial plexus, which consists of the nerves around the shoulder. Erb’s palsy is also referred to as brachial palsy, Erb-Duchenned paralysis or Klumpke paralysis. The condition differs from other kinds of palsy, and is marked by frailty or lack of movement in the arm. The disorder causes different degrees of impairment, which are described by some of the other names for the condition. When only the upper arm is affected, the condition is called a brachial plexus injury.
The ailment is labeled Erb’s paralysis when it affects movement of the upper arm and rotation of the lower arm. If movement of the hand is affected, the condition is called Klumpke paralysis, in which the eyelid can hang down on the side opposite to that of the affected hand.
