What is Erb’s palsy?
Erb’s palsy, also known as Erb-Duchenne palsy or brachial plexus birth palsy, is a condition that affects the movement and sensation of the arm. It occurs when the brachial plexus, a network of nerves near the neck that control movement and sensation in the arm, is injured during childbirth. This injury can happen if the baby’s shoulder becomes stuck behind the mother’s pubic bone during delivery, leading to stretching or tearing of the nerves.
Symptoms of Erb’s palsy can vary depending on the severity of the nerve injury, but they often include weakness or paralysis of the affected arm, loss of sensation, and limited range of motion. Treatment for Erb’s palsy may involve physical therapy, occupational therapy, splinting, or, in severe cases, surgery to repair the damaged nerves.
Early intervention is crucial for maximizing the potential for recovery and minimizing long-term complications associated with Erb’s palsy. With proper treatment and therapy, many individuals with Erb’s palsy can regain function and mobility in their affected arm.
Types of Erb’s palsy?
Erb's palsy typically results from injuries to the brachial plexus nerves, which are located near the neck and control movement and sensation in the arm. The most common types of injuries associated with Erb's palsy include:
- Stretch Injury: This occurs when the nerves of the brachial plexus are overstretched during childbirth, usually due to excessive pulling or stretching of the baby’s head and neck during delivery.
- Tearing Injury: In more severe cases, the nerves may tear partially or completely, leading to disruption of nerve function. This can happen if the baby’s shoulder becomes lodged behind the mother’s pubic bone during delivery.
- Compression Injury: Pressure on the brachial plexus nerves during delivery can also cause injury. This may occur if the baby’s shoulder is compressed against the mother’s pelvic bone or if forceps or vacuum extraction is used during delivery.

Who does Erb’s palsy affect?
Erb’s palsy can affect newborn babies, particularly those who experience difficult or traumatic deliveries. It’s more common in babies with larger birth weights or those born to mothers with smaller pelvic dimensions, which may increase the likelihood of shoulder dystocia during childbirth. Shoulder dystocia occurs when the baby’s shoulder becomes stuck behind the mother’s pubic bone during delivery, putting pressure on the brachial plexus nerves and potentially causing injury.
While Erb’s palsy primarily affects infants, it can also occur in adults as a result of trauma or injury to the brachial plexus nerves. This may happen due to car accidents, falls, sports injuries, or other traumatic events that impact the neck and shoulder region.
How common is Erb’s palsy (brachial plexus birth palsy) in newborns?
Erb’s palsy, also known as brachial plexus birth palsy, is a relatively rare condition that occurs in newborns. It’s estimated to affect around 1 to 2 births per 1,000 in the United States. However, the prevalence can vary based on factors such as the population studied and the criteria used for diagnosis. While it’s not extremely common, it’s still a significant concern for parents and healthcare providers due to its potential long-term impact on the affected child’s mobility and function.

What are the signs and symptoms of Erb’s palsy?
- Weakness or paralysis: The affected arm may have limited movement or be completely paralyzed. The extent of weakness or paralysis can vary depending on the severity of the injury to the brachial plexus nerves.
- Lack of muscle control: The muscles in the affected arm may lack normal tone and coordination, leading to difficulties in grasping, reaching, or lifting objects.
- Arm held against the body: The affected arm may be held close to the body, with the elbow bent and the forearm rotated inward. This posture is often referred to as the “waiter’s tip” position.
- Limited range of motion: The child may have difficulty moving the affected arm through its full range of motion, particularly in certain directions.
- Absent or reduced reflexes: Reflexes in the affected arm, such as the Moro reflex or the biceps reflex, may be diminished or absent.
- Sensory abnormalities: Some children with Erb’s palsy may experience sensory changes in the affected arm, such as numbness or tingling.
How is Erb’s palsy treated?
Treatment for Erb’s palsy typically depends on the severity of the condition and may include the following approaches:
Physical therapy: Physical therapy plays a crucial role in the treatment of Erb’s palsy. Therapists work with the child to improve muscle strength, range of motion, and coordination in the affected arm. Therapy exercises may include gentle stretching, passive range of motion exercises, and activities to promote muscle activation and development.
Occupational therapy: Occupational therapists may assist with activities of daily living and fine motor skills development, such as grasping objects and using utensils. They may also provide adaptive equipment or strategies to help the child compensate for any limitations in arm function.
Nerve surgery: In cases where conservative treatments are not effective or if there is severe nerve damage, surgical intervention may be considered. Nerve surgery, such as nerve grafting or nerve transfer, aims to repair or replace damaged nerves to restore function and improve muscle control in the affected arm.
Splinting or bracing: Splints or braces may be used to support the affected arm and maintain proper alignment during healing. These devices can help prevent contractures (shortening of muscles or tendons) and promote optimal positioning of the arm for improved function.
Medications: In some cases, medications may be prescribed to manage pain or muscle spasms associated with Erb’s palsy. These medications may include nonsteroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants.
Follow-up care: Regular follow-up appointments with healthcare providers are important to monitor the child’s progress, adjust treatment as needed, and address any complications or concerns that may arise.
The specific treatment plan for Erb’s palsy will vary based on individual factors, such as the child’s age, the severity of the condition, and the presence of any associated complications. Multidisciplinary care involving pediatricians, orthopedic surgeons, neurologists, and rehabilitation specialists is often recommended to ensure comprehensive management and optimal outcomes for affected children.
