Erb’s Palsy

What is Erb’s Palsy?

Erb’s Palsy, also known as Erb-Duchenne palsy or brachial plexus birth palsy, is a type of paralysis or weakness affecting the arm, typically due to damage to the nerves of the brachial plexus. The brachial plexus is a network of nerves originating from the spinal cord in the neck (specifically C5, C6, C7, C8, and T1 spinal nerves) that controls movement and sensation in the shoulder, arm, forearm, and hand. Erb’s palsy specifically involves injury to the upper nerves of the brachial plexus, most commonly C5 and C6.

Causes of Erb's Palsy

The most common cause of Erb’s palsy is a birth injury, often occurring during a difficult or complicated vaginal delivery. The injury happens when there’s excessive stretching or pulling of the baby’s head and neck in one direction while the shoulder is pulled in the opposite direction.

Factors that increase the risk of Erb's palsy during birth include:
  • Shoulder dystocia: This is when the baby’s shoulder gets stuck behind the mother’s pubic bone during delivery.
  • Large birth weight (macrosomia): Larger babies have a higher risk of shoulder dystocia.
  • Breech presentation: When the baby is born feet-first.
  • Prolonged or difficult labor.
  • Use of assistive delivery devices: Such as forceps or vacuum extractors, especially if excessive force is used.
  • Improper pulling or manipulation of the baby’s head or neck.
While less common, Erb’s palsy can also occur in older children or adults due to traumatic injuries like:
  • Motor vehicle accidents (especially motorcycle accidents)
  • Falls
  • Sports injuries (e.g., “burners” or “stingers” in contact sports)
The severity of the nerve damage can vary:
  • Neuropraxia: The nerve is stretched but not torn. This is the mildest form, and recovery is often complete.
  • Neuroma: Scar tissue forms around the nerve, which can interfere with nerve signals. Partial recovery is common.
  • Rupture: The nerve is torn, but not from the spinal cord. Surgery is often required for recovery.
  • Avulsion: The most severe type, where the nerve is torn completely from the spinal cord. This injury does not heal on its own and typically requires surgery.
Symptoms of Erb's Palsy

The symptoms of Erb’s palsy depend on the extent and type of nerve damage. They usually affect only one arm.

Common symptoms include:

  • Weakness or paralysis of the affected arm, shoulder, or elbow.
  • Limp or floppy arm: The arm may hang limply by the side.
  • “Waiter’s tip” position: A classic sign where the arm is held close to the body, elbow bent, shoulder rotated inward, and the forearm pronated with the palm facing backward or outward.
  • Reduced grip strength in the affected hand.
  • Limited range of motion in the shoulder, elbow, and sometimes the wrist and hand.
  • Loss of sensation or numbness in the affected arm.
  • Absent reflexes in the affected arm (e.g., Moro reflex).
  • Pain: While often painless in infants, older individuals with chronic or severe injuries may experience pain or a burning sensation.
  • Muscle atrophy: Over time, the affected arm may appear smaller or underdeveloped due to muscle wasting.
  • Joint stiffness (contractures): If not managed, tight muscles and tendons can lead to permanent joint deformities.
Advanced Physiotherapy for Erb's Palsy

Maintaining Range of Motion and Preventing Contractures

    • Passive Range of Motion (PROM) exercises: Gentle, regular movements of the shoulder, elbow, wrist, and hand by the therapist or parents/caregivers. This is vital to prevent joint stiffness (contractures) and maintain flexibility, especially during the initial recovery phase when active movement is limited.
    • Positioning: Advising parents on proper positioning of the infant’s arm during sleep, feeding, and play to support the limb and prevent abnormal postures (e.g., “waiter’s tip”).
    • Splinting/Orthotics: In some cases, custom-made splints or braces may be used to maintain optimal joint alignment, provide support, and prevent deformities.

Facilitating Muscle Activation and Strengthening

  • Neuromuscular facilitation techniques: Using gentle tapping, stroking, vibration, or approximation (gentle compression into the joint) to stimulate nerve and muscle activity and encourage active movement.
    • Graded strengthening exercises: Once some active movement returns, the therapist will introduce age-appropriate exercises to strengthen weak muscles. This can involve:
      • Assisted active movements: Helping the child perform movements.
      • Active exercises: Encouraging the child to move independently.
      • Resisted exercises: Gradually adding resistance (e.g., against gravity, resistance bands, light weights for older children) as strength improves.
      • Weight-bearing activities: Incorporating exercises where the child bears weight through the affected arm to promote muscle activation and joint stability.
  • Sensory Integration and Awareness:
    • Tactile stimulation: Gentle massage, different textures, and tapping to improve sensory awareness in the affected limb, as sensation can be diminished.
    • Proprioceptive activities: Activities that provide feedback about body position and movement (e.g., joint compression, weight-bearing).
  •  Functional Training and Bimanual Activities:
    • Task-specific training: Practicing activities that are meaningful and functional for the child’s age (e.g., reaching for toys, feeding oneself, dressing, playing with blocks).
    • Bimanual (bilateral) activities: Encouraging the use of both hands together to promote motor learning and integration of the affected arm into daily activities.
    • Constraint-Induced Movement Therapy (CIMT): For older children, this involves restraining the unaffected arm for periods to force the use of the affected arm, promoting neural rewiring and functional recovery.
  • Pain Management and Scar Tissue Management:
    • Massage: Gentle massage can help improve circulation, reduce discomfort, and manage scar tissue if surgery has been performed.
    • Stretching: To alleviate pain and improve flexibility in tight muscles.
