Fibromyalgia Pain Behaviour & Modulation

Pain Behavior

The behavioral responses to pain may allow for objective documentation to include in a database. Direct behavioural Observation of patients may include a request to perform standardized tasks thought likely to cause pain, such as sitting, walking, or bending. An observer notes visible or audible signs or expression of suffering or limited function as a measure of pain behavior (e.g., gasping, grimacing, or limping). A standardized scoring system may be used. These techniques have been used for low back pain." Indirect behavioral assessment may be possible through a questionnaire such as the Illness Behaviour Questionnaire (IBQ). This is a 52 item yes-no questionnaire that assesses attitudes towards illness, disease affliction, denial of psychosocial problems, ability to express affect, and affective disturbance. This instrument is based on the concept of "illness behavior," which refers to the ways in which individuals experience, perceive, evaluate, or respond to their health status. "Abnormal illness behavior" refers to inappropriate or maladaptive mode of experiencing, perceiving, evaluating, or responding to one's own state of health.x2

Pain Modulation - Neurophysiological changes

A large number of abnormalities of potential importance have been shown in various neurotransmitters in patients with FMS.90, 102. At this time, these observations cannot be used in the everyday clinic situation. Similarly, regional cerebral blood flow changes, as shown on single photon-emission computed tomography, require further observations in regard to specificity and sensitivity and remain in the research area.
