[Chronic whiplash syndrome--an overview]

Area of Science:

• Biopsychosocial Medicine
• Pain Syndromes
• Traumatology

Background:

• Significant international discrepancies exist in the reported incidence and severity of chronic whiplash syndrome.
• Whiplash is perceived differently across regions, ranging from widespread chronic conditions to transient, mild symptoms.

Purpose of the Study:

• To explain the global variations in chronic whiplash syndrome prevalence.
• To introduce a biopsychosocial model to account for these discrepancies.
• To analyze the role of psychological factors and medico-legal contexts in symptom perception and chronicity.

Main Methods:

• Exploration of a biopsychosocial model incorporating population-based symptom pools.
• Analysis of psychological mechanisms including attribution, expectation (nocebo effect), and reinforcement.
• Consideration of behavioral factors, treatment effects, and medico-legal influences on symptom reporting and assessment.

Main Results:

• Common, spontaneously occurring symptoms (e.g., head and neck pain) can be psychologically attributed to mild or moderate trauma.
• Inappropriate patient behavior, suboptimal treatments, conscious symptom exaggeration, and underreporting in medico-legal settings can prolong symptoms.
• A causal link between common whiplash injuries and chronic complaints is not generally demonstrated, requiring strict criteria for acceptance in litigation.

Conclusions:

• The biopsychosocial model effectively explains the varied presentation of whiplash injuries worldwide.
• Psychological factors and external influences significantly modulate symptom experience and chronicity.
• Causality in chronic whiplash claims requires rigorous evidence, as widespread attribution to mild trauma is often unsubstantiated.
