What is Erb’s Palsy?
Erb’s Palsy is a condition caused by injury to the upper part of the brachial plexus, a network of nerves that travels from the neck through the shoulder and into the arm and hand.
The brachial plexus carries nerve signals that control movement and sensation in different parts of the upper limb. In Erb’s Palsy, the upper nerve roots, commonly C5 and C6, and sometimes additional nerve roots, may be stretched, compressed, or injured.
When these nerves are affected, muscles around the shoulder and upper arm may become weak or difficult to control. The severity can vary significantly depending on the type and extent of nerve injury.
Some children may show gradual improvement over time, while others may require ongoing specialist care, physiotherapy, or, in selected cases, surgical assessment. Early evaluation and regular monitoring are important because the recovery and treatment plan depend on the individual child’s nerve injury and functional development.
The condition is commonly associated with birth-related brachial plexus injury, but similar upper brachial plexus injuries can also occur following trauma in older children or adults.
What Are The Symptoms Of Erb’s Palsy?
Weakness in the Affected Arm: The child may have reduced strength or little active movement in one arm.
Reduced Shoulder Movement: Lifting or moving the arm away from the body may be difficult due to weakness affecting the shoulder muscles.
Difficulty Bending the Elbow: Weakness in muscles responsible for elbow bending may reduce the child’s ability to bring the hand towards the face or body.
Reduced Arm Movement: The affected arm may move less than the unaffected arm, particularly during early infancy.
Characteristic Arm Position: The arm may rest close to the body with the shoulder turned inward and the forearm positioned in a particular direction. The exact position can vary.
Reduced Muscle Activity: Certain muscles around the shoulder and upper arm may show reduced activity because of the affected nerve supply.
Reduced Sensation: Depending on the extent of nerve involvement, changes in sensation may occur in parts of the arm.
Delayed Functional Arm Use: The child may be slower to develop normal use of the affected arm during reaching, grasping, play, or other age-appropriate activities.
Joint Stiffness: Reduced movement over time can contribute to stiffness and reduced joint mobility if appropriate movement and positioning are not maintained.
Muscle Imbalance: Differences in muscle strength around the shoulder may affect joint alignment and movement as the child grows.
What Are The Causes Of Erb’s Palsy?
Birth-Related Brachial Plexus Injury: Erb’s Palsy commonly develops when the baby’s shoulder or neck is subjected to excessive stretching during a difficult delivery.
Shoulder Dystocia: When the baby’s shoulder becomes difficult to deliver, increased traction or force around the neck and shoulder region may increase the risk of brachial plexus injury.
Difficult or Assisted Delivery: Certain complicated deliveries may increase the risk of injury to the brachial plexus.
Large Birth Size: Larger babies may have a higher risk of certain delivery complications, including shoulder dystocia.
Breech Delivery: In some cases, difficult delivery of a baby in a breech position may contribute to brachial plexus injury.
Traumatic Injury: In older children or adults, injuries such as falls, sports trauma, road traffic accidents, or forceful stretching of the neck and shoulder can cause similar upper brachial plexus injuries.
The severity of the nerve injury can range from temporary stretching to more significant nerve damage. The child’s prognosis depends on the specific nerves affected and the extent of the injury.
Diagnosis Of Erb’s Palsy
Medical and Birth History: The healthcare professional will review the pregnancy, delivery, possible birth complications, and when reduced arm movement was first noticed.
Physical Examination: The affected arm is assessed for active movement, muscle strength, joint position, reflexes, and symmetry compared with the unaffected arm.
Brachial Plexus Assessment: The shoulder, elbow, wrist, and hand are assessed to understand which movements and muscle groups are affected.
Developmental Assessment: The child’s ability to use the affected arm during age-appropriate activities such as reaching, grasping, rolling, crawling, and play may be monitored.
Range of Motion Assessment: Joint movement is assessed to identify stiffness or the risk of developing movement limitations.
Neurological Examination: A specialist may assess nerve and muscle function to determine the likely extent and location of the injury.
Ultrasound or MRI: In selected cases, imaging may be considered to assess relevant nerves, muscles, or joints.
Electrodiagnostic Tests: Tests such as nerve conduction studies or electromyography may be considered in selected cases to assess nerve and muscle activity.
Specialist Follow-Up: Regular review by an appropriate paediatric or brachial plexus specialist may be necessary to monitor recovery and determine whether additional treatment is required.
Treatment Of Erb’s Palsy
Early Specialist Assessment: Early evaluation helps determine the severity of the nerve injury and establish an appropriate monitoring and treatment plan.
Physiotherapy: A personalised physiotherapy programme may help maintain joint mobility, support muscle activity, prevent secondary stiffness, and encourage functional use of the affected arm.
Positioning Guidance: Parents and caregivers may receive guidance on appropriate handling and positioning of the child’s affected arm.
Gentle Range of Motion Exercises: Where recommended, carefully guided movements may help maintain available mobility in the shoulder, elbow, and other joints.
Developmental Activities: Age-appropriate activities and play may be used to encourage movement and functional use of the affected arm.
Splinting or Orthotic Support: In selected cases, a specialist may recommend suitable splints or orthotic devices to support joint position and function.
Monitoring Muscle and Joint Development: Regular assessment helps identify changes in movement, strength, muscle development, and joint alignment as the child grows.
Botulinum Toxin or Other Specialist Treatments: In selected cases, specialist treatments may be considered depending on muscle imbalance and the child’s individual condition.
Surgical Assessment: Children with more significant nerve injuries or insufficient recovery may be referred to a specialist team to consider procedures such as nerve repair, nerve grafting, or nerve transfer when clinically appropriate.
What Is The Physiotherapy Treatment Of Erb’s Palsy
Detailed Paediatric Assessment: At Pure Physio, treatment begins with assessing the child’s active arm movement, joint mobility, muscle activity, developmental stage, functional abilities, and individual rehabilitation needs.
Maintaining Joint Mobility: Carefully guided exercises may help maintain available movement in the shoulder, elbow, forearm, wrist, and hand where appropriate.
Preventing Stiffness: Regular age-appropriate movement and positioning strategies may help reduce the risk of secondary joint stiffness caused by reduced active arm movement.
Encouraging Active Movement: Therapy uses suitable activities to encourage the child to actively move and use the affected arm.
Age-Appropriate Play Therapy: Reaching, grasping, touching, and other play-based activities may be incorporated to encourage natural movement and functional use.
Shoulder and Arm Strengthening: As the child develops sufficient muscle activity, appropriate activities may be used to encourage gradual strengthening and improved control.
Functional Movement Training: Therapy focuses on helping the child use the affected arm during meaningful activities appropriate to their developmental stage.
Bilateral Activities: Carefully planned activities may encourage the use of both hands and arms during play and everyday tasks.
Positioning and Handling Education: Parents and caregivers receive guidance on appropriate handling, positioning, and home activities according to the child’s treatment plan.
Developmental Milestone Support: Physiotherapy may support relevant developmental skills such as reaching, rolling, sitting, crawling, and other age-appropriate movements.
Regular Progress Monitoring: The child’s movement and functional development are reviewed regularly, and the rehabilitation programme is adjusted according to progress and specialist guidance.
