title: [Behavioral aspects of chronic pain syndromes].
abstract: The knowledge of biological pain mechanisms are not sufficient for the understanding of patients with chronic pain syndromes such as low back, cervicobrachial and muscle pain. Psychological and psychosocial aspects play important roles in the setting and perpetuation of symptoms. Mood and anxiety disorders, secondary gains such as early retirement and financial compensations, must all be acknowledged by the physician as possible contributors to the symptoms. Abnormal illness behavior may better characterize patients with chronic pain syndromes. Behavior observation, which is akin to medical practice, is therefore a powerful tool in the diagnosis and management of these syndromes. Physicians ought be very careful in not reinforcing the patients already strong organic convictions regarding their symptoms, avoiding making decisions based on patients complaints and alleged disabilities, and assigning poorly defined and disputable diagnosis labels. Society needs also to refrain from policies that encourage abnormal illness behaviors.
