Erb's Palsy Treatment
What are the signs and symptoms of Erb’s palsy?
Erb’s palsy, also known as Erb-Duchenne paralysis, is a condition that results in weakness or loss of muscle function in the shoulder and arm. The signs and symptoms of Erb’s palsy can vary in severity and may be temporary or permanent. Here are some common signs and symptoms of Erb’s palsy:
Weakness or Paralysis: One of the most noticeable signs of Erb’s palsy is weakness or paralysis in the arm, shoulder, or elbow joint. The affected arm may appear limp or paralyzed.
Tingling and Numbness: Individuals with Erb’s palsy may experience tingling and numbness in the arm or hand. This can be a result of damage to the nerves that provide sensation to these areas.
Reduced Grip Strength: Another common symptom is reduced grip strength in the hand. This can make it difficult for the individual to grasp objects or perform tasks that require fine motor skills.
Abnormal Arm Position: The affected arm may be held in an awkward position. For example, the palm of the hand may be curved backward, and the fingers may be curled.
Lack of Movement: One of the first signs a doctor or new parent may detect in an infant is a lack of movement or weakness in the affected arm3. Although motor control is limited in newborns, infants move their arms around right after birth. If one arm moves and the other does not, it is likely a sign of Erb’s palsy.
These symptoms can range from mild to severe, depending on the extent of the nerve damage. It’s important to consult with a healthcare provider if you notice any of these symptoms in yourself or your child, as early intervention can improve the prognosis.
How is Erb’s palsy diagnosed?
Erb’s palsy is diagnosed through a combination of physical examination and diagnostic tests. During the physical examination, healthcare professionals check for symptoms such as weakness or paralysis in the affected arm, lack of movement in the hand or arm, and decreased reflexes. To determine the severity of the Erb’s palsy, one or more of the following tests may be required:
X-ray: An X-ray of the shoulder and neck can show fractures or other related injuries.
Electromyography (EMG): This test measures the electrical activity of the muscles to assess their health and the nerves controlling them.
Neurological and Sensation Assessments: These assessments study your child’s muscle tone, reflexes, spontaneous movements, and sensations.
Movement and Motor Tests: There are two main motor and movement tests doctors can conduct to assess for Erb’s palsy: the passive range-of-motion (PROM) examinations and the active movement scale (AMS).
Imaging and Electrodiagnosis: These tests can help visualize the brachial plexus and assess the extent of nerve damage.
These tests help healthcare professionals understand the extent of the nerve damage and guide the treatment plan. It’s important to note that the symptoms of Erb’s palsy can vary in severity and may be temporary or permanent. Therefore, early diagnosis and intervention can improve the prognosis.
How is Erb’s palsy treated?
The treatment of Erb’s palsy depends on the severity of the injury. Some cases may resolve by themselves within three to four months. However, most likely, healthcare providers will suggest that you do exercises and physical therapy with your baby from about the age of three weeks.
Non-Surgical Treatments: Daily physical therapy is the most effective treatment for Erb’s palsy. This involves a series of exercises that parents can do at home with their child. These exercises help maintain the range of motion in the baby’s arm and prevent stiffness. They also help improve blood circulation to the affected nerves, which can promote healing.
Surgical Procedures: If physical therapy doesn’t show promising results after three to six months, your physician may recommend surgery to repair damaged nerves. The type of surgery depends on the severity of the nerve damage. For example, for avulsion injuries where the nerve is torn from the spinal cord, a nerve graft or nerve transfer may be performed. For less severe injuries, neurolysis (the removal of scar tissue from the nerve) may be sufficient.
Post-Treatment Rehabilitation: After treatment, whether non-surgical or surgical, ongoing physical therapy and occupational therapy are usually needed. These therapies help improve fine motor skills, strength, and function in the affected arm.
Complications: Most infants and older patients with Erb’s palsy will recover strength and movement in the affected arm. However, some may experience lasting effects, such as limited movement or reduced muscle control.
The treatment of Erb’s palsy involves a combination of physical therapy, possibly surgery, and post-treatment rehabilitation. The specific treatment plan depends on the severity of the condition and the individual’s response to therapy.
