What are the general guidelines for physical therapy (PT) specialists in the rehabilitation of Guillain-Barré Syndrome (GBS), including management of autonomic dysfunction, fatigue, proprioceptive sensory loss, and respiratory dysfunction?

Comprehensive Rehabilitation Guidelines for Guillain-Barré Syndrome

A multidisciplinary rehabilitation program is essential for optimal recovery in Guillain-Barré Syndrome (GBS), addressing not only weakness but also autonomic dysfunction, fatigue, proprioceptive sensory loss, and respiratory complications across all stages of recovery. 1

Initial Assessment and Monitoring

• Autonomic Dysfunction Management:

  • Monitor heart rate, blood pressure, and bowel/bladder function via electrocardiography 2
  • Stay vigilant for dysautonomia throughout recovery, as up to two-thirds of GBS deaths occur during recovery phase due to cardiovascular and respiratory complications 2
  • Position changes should be gradual to prevent orthostatic hypotension
  • Monitor for arrhythmias and blood pressure fluctuations, especially in patients recently discharged from ICU 2

• Respiratory Function:

  • Implement regular respiratory assessments including vital capacity, negative inspiratory force, and oxygen saturation
  • Provide chest physiotherapy, breathing exercises, and airway clearance techniques to prevent mucus plugs 2
  • Teach effective coughing techniques for patients with bulbar involvement
  • Consider mechanical insufflation-exsufflation devices for those with weak cough

Early Rehabilitation Phase (ICU/Acute Care)

• Positioning and Range of Motion:

  • Implement proper positioning to prevent pressure ulcers and contractures
  • Perform passive range-of-motion exercises 2-3 times daily 1
  • Use ankle-foot orthoses to prevent foot drop
  • Consider splinting for hand positioning

• Pain Management:

  • Address neuropathic pain (affects at least one-third of patients) with:
    • Pharmacological: gabapentinoids, tricyclic antidepressants 1
    • Non-pharmacological: gentle massage, TENS, positioning
  • Recognize deafferent pain syndromes in early recovery stages 3

• Psychological Support:

  • Provide psychological support recognizing that patients typically have intact consciousness despite paralysis 1
  • Explain all procedures to reduce anxiety 2
  • Consider early psychiatric consultation for hallucinations, anxiety, or depression 2

Intermediate Rehabilitation Phase

• Fatigue Management:

  • Implement energy conservation techniques for the 60-80% of patients experiencing fatigue 1
  • Schedule regular rest periods between therapy sessions
  • Monitor exercise intensity carefully to avoid overexertion 1
  • Do not push patients beyond their fatigue threshold 1

• Progressive Mobility Program:

  • Begin with bed mobility exercises
  • Progress to sitting balance activities
  • Advance to standing exercises with appropriate support
  • Implement gait training with assistive devices as appropriate

• Proprioceptive Training:

  • Incorporate visual feedback during exercises (mirrors, video)
  • Implement weight-bearing activities to enhance proprioceptive input
  • Use balance boards and unstable surfaces with appropriate safety measures
  • Train compensatory strategies using visual cues for those with severe sensory loss

Advanced Rehabilitation Phase

• Structured Exercise Program:

  • Implement high-intensity programs (3-5 sessions weekly) which show better outcomes than low-intensity programs 1
  • Include:
    • Progressive resistance training
    • Endurance training
    • Functional mobility training
    • Balance and coordination exercises
    • Stationary cycling 1

• Activities of Daily Living (ADL) Training:

  • Focus on functional tasks required for independence
  • Provide adaptive equipment as needed
  • Train in energy conservation techniques during ADLs
  • Practice transfers and mobility in home-like environments

• Miller Fisher Variant Considerations:

  • Emphasize oculomotor exercises for ophthalmoplegia
  • Implement vestibular rehabilitation techniques for ataxia
  • Address facial weakness with specific facial exercises
  • Provide visual compensation strategies for diplopia

Long-Term Management

• Ongoing Assessment:

  • Use standardized tools like Functional Independence Measure (FIM) and Modified Erasmus GBS Outcome Score (mEGOS) 1
  • Regularly reassess for treatment-related fluctuations (TRFs), which occur in 6-10% of patients within 2 months of initial treatment 2, 1
  • Monitor for progression to chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) if symptoms continue after 8 weeks (occurs in ~5% of cases) 2, 1

• Community Reintegration:

  • Provide vocational counseling and workplace accommodations
  • Assess driving capability and provide training if needed
  • Connect patients with peer support groups 1
  • Consider school reintegration planning for adolescents 1

Common Pitfalls and Caveats

• Overexertion Risk:

  • Excessive exercise can cause paradoxical weakening of the motor unit 3
  • Monitor for post-exertional malaise and adjust program accordingly

• Persistent Symptoms:

  • Fatigue and neuropathic pain may persist for years despite functional improvement 4
  • Recovery from residual complaints can occur even >5 years after disease onset 2

• Medical Complications:

  • Remain vigilant for deep venous thrombosis, joint contractures, hypercalcemia of immobilization, and pressure ulcers 3
  • Anemia is common in early months but doesn't appear to interfere with functional recovery 3

• Prognosis Communication:

  • Provide accurate information about the generally positive prognosis (80% regain walking ability within 6 months) 2
  • Acknowledge the 3-10% mortality rate due to cardiovascular and respiratory complications 2, 1

By implementing this comprehensive rehabilitation approach addressing all aspects of GBS beyond weakness alone, physical therapists can significantly improve functional outcomes and quality of life for patients with this challenging condition.
