Empirical evidence that different pain-behavioral models - defined as fear-avoidance, endurance/over-activity and pacing may characterize daily functioning in chronic pain patients.

Each bubble contains subject's specific information about the cumulated activity(%) level (on the y-axis) and the statistical distance between distribution of activity and rest periods, (in the bubble relative size): fear-avoidance behavior might be attributed to the chronic pain patients with low activity levels while endurance might be attributed to the severe pain patients who perform high amounts of activity levels, comparable with no/moderate pain subjects. Pacing behavior might be associated to the chronic pain patients with high level of cumulated activity but with a more fragmented pattern and longer rest periods compared to activity periods (i.e. bigger bubble sizes, as observed for the patients in the severe pain, middle age group compared to the subjects in the no pain, middle age group).
