An application of the fear avoidance model to three chronic pain problems.

The Fear Avoidance Model of Exaggerated Pain Perception was developed in an attempt to explain how, and why, some individuals develop a more substantial psychological overlay to their low back pain problem than do others. The present paper describes a study in which three chronic pain groups, consisting of Post-Herpetic neuralgia patients, Reflex Sympathetic Dystrophy patients and chronic low back pain patients were compared with three pain-free comparison groups using the Fear Avoidance Model of Exaggerated Pain Perception. The results show statistically significant differences between the chronic groups and the recovered comparison groups. These results demonstrate the usefulness of the Fear Avoidance Model as an explanation of psychological overlay in chronic pain conditions regardless of pathology.
