[The sensitization model: a method to explain chronic pain to a patient]

Area of Science:

• Neuroscience
• Pain Medicine
• Psychology

Context:

• Chronic pain frequently lacks a clear diagnosis, leading to patient distress and a search for alternative explanations.
• Many chronic pain syndromes, including low-back pain, whiplash, and fibromyalgia, share a common pathogenesis.
• Central nervous system sensitization is increasingly recognized as a key mechanism in chronic pain.

Purpose:

• To explore the pathogenesis of chronic pain syndromes through the lens of central nervous system sensitization.
• To investigate the role of medical, psychological, and social factors in the development and persistence of sensitization.
• To advocate for a bio-psycho-social model in understanding and managing chronic pain.

Summary:

• Chronic pain may arise from sensitization of central pain-modulating systems, rather than a clear somatic cause.
• This sensitization is influenced by a complex interplay of medical, psychological, and social factors, varying individually.
• Explaining sensitization and its contributing factors to patients can foster treatment acceptance and coping strategies.

Impact:

• Provides a unified explanation for diverse chronic pain syndromes.
• Highlights the importance of a bio-psycho-social approach in pain management.
• Empowers patients by explaining the mechanisms of their pain and facilitating acceptance of management strategies.
