Outline of Final Research Achievements

We investigated correlations between bodily self-consciousness and pain, depression, anxiety, and pain catastrophizing in patients with chronic intra-oral pain. Age-matched control subjects were also recruited in this study. In control subjects, bodily self-consciousness, which is measured by tongue size estimation, did not correlate with any parameters. On the other hand, in patients with chronic intra-oral pain, tongue size estimation significantly negatively correlated with magnification, which is one of the subscales in the pain catastrophizing scale. These results suggest that thinking about pain is associated with bodily self-consciousness in patients with chronic pain.
