Overview

Fibromyalgia is a chronic condition characterized by widespread musculoskeletal pain, fatigue, and tenderness, often accompanied by sleep disturbances and cognitive difficulties 22.

Diagnosis

  • Key Criteria: Utilize the 2016 American College of Rheumatology (ACR) criteria, which include widespread pain and cognitive symptoms 134041.
  • Recommended Tests: No specific laboratory tests are definitive; however, assessing ferritin, vitamin D, and vitamin B12 levels may provide supportive information 3.
  • Validation: Criteria validated across various populations including Chinese and Spanish 1366.
  • Management

  • First-Line Treatments:
  • - Therapeutic Exercises: Strong recommendation for aerobic and strengthening exercises 2420. - Cognitive Behavioral Therapy (CBT): Effective in managing symptoms 225.
  • Adjunctive Treatments:
  • - Transcranial Direct Current Stimulation (tDCS): Shows promise in reducing pain and improving function 101127. - Vitamin D Supplementation: Emerging evidence suggests potential benefits 1855. - Myofascial Release: Limited evidence suggests possible improvements in pain and quality of life 30.

    Special Populations

  • Pediatrics: Limited data; criteria adapted from adult criteria may not fully apply 73.
  • Elderly: Mindfulness interventions show potential effectiveness 15.
  • Comorbidities: Consider interactions with conditions like irritable bowel syndrome and small fiber neuropathy 844.
  • Key Recommendations

  • Implement Regular Therapeutic Exercises: Aerobic and strengthening exercises are strongly recommended for symptom management (Evidence: Strong 2420).
  • Consider Cognitive Behavioral Therapy (CBT): CBT should be integrated into treatment plans for psychological aspects of fibromyalgia (Evidence: Moderate 225).
  • Evaluate and Supplement Vitamin D Levels: Given the potential role of vitamin D deficiency, supplementation should be considered in deficient patients (Evidence: Moderate 1855).
  • Explore Transcranial Direct Current Stimulation (tDCS): Use of tDCS for pain reduction and functional improvement can be adjunctive (Evidence: Moderate 101127).
  • Monitor for Comorbid Conditions: Screen for and manage comorbidities such as irritable bowel syndrome and small fiber neuropathy (Evidence: Expert opinion 844).
