Outline of Final Research Achievements

We carried out saliva cortisol test for the subject 27 people, EEG, ERP, threshold (sensory-pain), and psychological test, respectively. Then, we started interventions for each subject. By the end of study period, we finished the data analysis except EEG mapping. This study revealed that the shorter the reaction time with the increase of the number of attempts ABM. In addition, the value of cortisol after ABM intervention was significantly reduced as compared to the values of cortisol before baselinet. However, for pain threshold and sensory threshold, there was no change before and after the test. Because cortisol was decreased by intervention, ABM intervention may attenuate some biological stress markers.
