Erb's Palsy Overview
Learn About Erb's Palsy
The brachial plexus is a group of nerves around the shoulder. A loss of movement or weakness of the arm may occur if these nerves are damaged. This injury is called neonatal brachial plexus palsy (NBPP).
Klumpke paralysis; Erb-Duchenne paralysis; Erb's palsy; Brachial palsy; Brachial plexopathy; Obstetrical brachial plexus palsy; Birth-related brachial plexus palsy; Neonatal brachial plexus palsy; NBPP
The nerves of the brachial plexus can be affected by compression inside the mother's womb or during a difficult delivery. Injury may be caused by:
- The infant's head and neck pulling toward the side as the shoulders pass through the birth canal or surgical incision
- The infant's shoulders stretching or arm being pulled during a head-first delivery
- Pressure on the baby's raised arms during a breech delivery
There are different forms of NBPP. The type depends on the amount of arm paralysis:
- Brachial plexus palsy most often affects only the upper arm. It is also called Duchenne-Erb or Erb-Duchenne paralysis.
- Klumpke paralysis affects the lower arm and hand. This is less common.
The following factors increase the risk of NBPP:
- Breech delivery
- Maternal obesity
- Larger-than-average newborn (such as an infant of a diabetic mother)
- Difficulty delivering the baby's shoulder after the head has already come out (called shoulder dystocia)
NBPP is less common than in the past. Cesarean delivery (C-section) is used more often when there are concerns about a difficult delivery. Although a C-section reduces the risk of injury, it does not prevent it. A C-section also carries other risks.
NBPP may be confused with a condition called pseudoparalysis. This is seen when the infant has a fracture of the clavicle (collarbone) and is not moving the arm because of pain, but there is no nerve damage.
Symptoms can be seen right away or soon after birth. They may include:
- No movement in the newborn's upper or lower arm or hand
- Absent Moro reflex on the affected side
- Arm extended (straight) at elbow and held against body
- Decreased grip on the affected side (depending on the site of injury)
In mild cases, the provider will suggest:
- Gentle massage of the arm
- Range-of-motion exercises
Pediatric physical therapists can help with these. The infant may need to be seen by specialists if the damage is severe or the condition does not improve in the first few weeks.
Surgery may be considered if strength does not improve by 3 to 9 months of age.

Most babies will fully recover within 3 to 4 months. Those who do not recover during this time have a poor outlook for full recovery. In these cases, there may have been a separation of the nerve root from the spinal cord (avulsion).
It is not clear whether surgery to fix the nerve problem can help. Surgery may involve nerve grafts or nerve transfers. It may take many years for healing to occur.
In cases of pseudoparalysis, the child will begin to use the affected arm as the fracture heals. Fractures in infants heal quickly and easily in most cases.
Complications include:
- Abnormal muscle contractions (contractures) or tightening of the muscles. These may be permanent.
- Permanent, partial, or total loss of function of the affected nerves, causing paralysis of the arm or arm weakness.
Contact your provider if your newborn is not moving an arm.
It is difficult to prevent NBPP. Taking steps to avoid a difficult delivery, whenever possible, reduces the risk.
Summary: The aim of this methodological study is to translate the Impact of Brachial Plexus Injury Questionnaire (IMBPIQ) into Turkish, culturally adapt it, and evaluate its validity and reliability for use in adults with brachial plexus birth palsy. The study will include 50 adult participants aged 18 years and older with a diagnosis of brachial plexus birth palsy. Participants will complete the Turkish v...
Summary: The purpose of this research study is to demonstrate the safety and efficacy of using two CRS Arrays (microelectrodes) for long-term recording of brain motor cortex activity and microstimulation of brain sensory cortex.
