The origin of functional somatic symptoms cannot be detected by regular medical examination, because the abnormalities don't accompany visual changes typically. Moreover, functional somatic symptoms are involved in stress. Considering these things and pathophysiology, we evaluated the response of ANS-related physiological parameters to stress.
Psychophysiological stress profiling (PSP) is a method of estimating the response to a stress by simultaneously measuring multiple physiological parameters based on the concept of autonomic response specificity (7,8). PSP also include psychological measurements as we consider both pathophysiology a) and b) above.
