Abstract

In our previous study, we performed biofeedback (BF) therapy (direct method) and electroencephalogram (EEG)-BF therapy (indirect method) by using a monitoring system (harmonized alert sensing technology ; HASTE) that is used in hospital wards and other treatment centers for treating hypertension/white-coat hypertension, and we clarified the effectiveness of these therapy systems. In this study, we compare the effects of both the direct and indirect BF therapy methods combined with relaxation therapy. The results for both the study groups revealed significant reductions in blood pressure during the shrinkage period, in general blood pressure, and in the plasma levels of adrenaline and significant improvements in anxiety and depression. As compared to the results obtained for these 2 groups, we observed more significant blood pressure reductions among patients who visited the outpatient clinic (for the shrinkage period : 1〜4 times, a diastole : 1〜7 times) by using the direct method (combined with relaxation) than by using the indirect method (combined with relaxation) In summary, the direct method (combined with relaxation) influences blood pressure at an earlier stage than the indirect method (combined with relaxation) does, and the former is effective even after 6 months.
