Power spectrum analysis is a powerful noninvasive tool for quantifying autonomic nervous system activity. In this paper, We developed a measuring system for Autonomic Nervous Activity by using power spectrum analysis method to obtain the activities of autonomic nervous system. This system adopt a isolated power for patient's safety. In this system, Two output signal is obtained - R-R interval time variability and Respiration time variability. Time variability is use to find out some disease related to Autonomic Nervous System. Experimental tested range is 30 ～ 240 BPM for ECG and 15～80 BPM for Respiration.

This study was designed to clarify the effect of juniper essential oil on the autonomic nervous system. Blood pressure and heart rate variability (HRV) reflecting autonomic nervous system activity were measured. The systolic and diastolic blood pressure were decreased by inhalation of juniper essential oil. High frequency (HF) power level, an indicator of parasympathetic nervous system activity was increased in the stimulation of juniper essential oil. High frequency/low frequency (HF/LF) ratio, an indicator of sympathetic nervous system activity was decreased by the juniper essential oil. These results suggest that juniper essential oil has a modulatory effect on the autonomic nervous system activity.

The purpose of this study is to explore the effects of Chamaecyparis obtusa essential oil on the activity of autonomic nervous system. Heart rate variability (HRV), as an indicator of autonomic nervous system activity and blood pressure were measured before and after inhalation of Chamaecyparis obtusa essential oil. The systolic blood pressure was decreased by inhalation of Chamaecyparis obtusa essential oil (p<0.05). The diastolic blood pressure was not changed significantly by Chamaecyparis obtusa. High frequency (HF) power level was not changed but High frequency/Low frequency (HF/LF) ratio was decreased by Chamaecyparis obtusa essential oil (p<0.05), meaning that parasympathetic nervous system activity was not affected but sympathetic nervous system activity was decreased. These results indicate that Chamaecyparis obtusa essential oil has a modulatory effect on the autonomic nervous system activity.

Background: The consequences of disordered breathing patterns are not only distressing to the patient but also expensive to our health care systems if they are not diagnosed and treated. So we performed this study to investigate clinical significants trough gigong, yoga and hyperventilation in oriental medicine and westen medicine Objective: To review the relationship of electrogastrography with autonomic nervous system and to study its clinical application. Method: We investigate the research results through internet search engine, Pubmed. Conclusion: Electrogastrography is a reliable, non-invasive method for recording gastric myoelectrical activity and is used for objectification of diagnosis related to gastric peristalsis. Gastric myoelectrical activity seem to involve autonomic nervous system, especially parasympathetic nervous system. The study should be continuing about relationship between electrogastrography and autonomic nervous system.

Following thesis is about comprehensive treatment of insomnia through stability of the autonomic nervous system. It is widely accepted that most of the relevant symptoms of insomnia can be blamed on successive instability of the autonomic nervous system. In order to treat insomnia effectively, it is essential to maintain stability in the autonomic nervous system. When one is at stable stage of the autonomic nervous system, one maintains steady hormonal discharge. In Oriental Medicine, it is the stage when one has a sound qi-blood circulation. To treat insomnia effectively, one has to obtain both physical and mental relaxation through various ways.

Purpose: This study was to identify the effects of laughing and music therapy on depression and the activities of the autonomic nervous system in the elderly with dementia. Methods: The participants were 61 seniors over 65 years old with dementia, admitted to nursing homes. Twenty of them received laughing therapy, 21 received music therapy and 18 were in the control group. A total of 59 patients' data were analyzed. Depression was measured by Cornell Scale for Depression in Dementia tool, and the activities of the autonomic nervous system by the heart rate variability measuring device. The data were analyzed by frequency and percentage, Chi-square test, t-test, ANOVA, and Tukey test. Results: The depression of the music therapy group was more significantly decreased than the laughing therapy group and the control group. The activities of the autonomic nervous system of the laughing therapy group were more significantly increased than the music therapy group. The magnitude of the activities of the autonomic nervous system of the laughing therapy group were more significantly increased than the music therapy group. Conclusion: This study showed that music therapy was more effective than laughing therapy for the decrease of depression. Laughing and music therapy were more effective than in the control group for increasing the activities of the para-sympathetic nervous system and decreasing the activities of the sympathetic nerve system.

PURPOSE : The effect of the vestibular caloric stimulation with ice water on the autonomic nervous system was investigated using pulse oximetry. METHOD : Thirty-four healthy men and women were subject to a 2-minute vestibular caloric stimulation with ice water, and autonomic nervous activities (low frequency, high frequency, and total power) were measured before and after the vestibular caloric stimulation. Data were analyzed separately for men and women. RESULT : Low frequency, high frequency, and total power in the men and low frequency in the women were statistically significantly higher after vestibular caloric stimulation. High frequency and total power in the women were higher but not significantly different after vestibular caloric stimulation. CONCLUSION : Vestibular caloric stimulation with ice water increases autonomic nervous activities, with the variation being within the normal range. The test can be considered safe for use.

There are many hypothesis about mechanism of acupuncture, and the relationship between acupuncture stimulation and autonomic nervous system(ANS) is one of the powerful hypothesis. The purpose of this study is to investigate the relationship between acupuncture stimulation and ANS. We searched the literature and reports related with acupuncture stimulation(meridian system, meridian points) and autonomic nervous system. And we concluded acupuncture stimulation can control autonomic nervous system. We reviewed studies that contributed to an understanding of the autonomic mechanisms of acupuncture with the hope that this review will be of benefit to the acupuncture treatment.

By far, studies on the effect of oral administration of peppermint essential oil on blood pressure are not consistent, increasing or decreasing. And the effect of inhalation of peppermint essential oil on blood pressure was not reported. This study was designed to clarify the effect of peppermint essential oil inhalation on the blood pressure and autonomic nervous system. Blood pressure and heart rate variability (HRV) as an indicator of autonomic nervous system activity were measured. The systolic and diastolic blood pressure was not changed significantly by inhalation of peppermint essential oil. Standard deviation of normal to normal (SDNN), a parameter of total activity of autonomic nervous system also was not changed significantly. High frequency (HF) power level, an indicator of parasympathetic nervous system activity was not changed by peppermint. These results indicate that action mechanism of peppermint essential oil on blood pressure is different by the method of administration, oral or inhalation.

PURPOSE: The purpose of this study is to investigate the effect of the physical therapy treatment room environment using microwave diathermy on the autonomic nervous system of human body. METHODS: Participants were 24 healthy adults. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences(RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were compared in microwave irradiation and non-irradiation group. Data were analyzed in Wilcoxon's signed-ranks test and Mann-Whitney U test. RESULTS: Standard deviation of all normal R-R intervals (SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different in microwave irradiation group. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different in microwave non-irradiation group. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different between two groups. CONCLUSION: There was no significant change in the sympathetic nervous system and parasympathetic nervous system regardless of the presence of microwave irradiation. There was no significant change in the autonomic nervous system adaptability regardless of the presence of microwave irradiation.According to this study, microwave diathermy does not have significant effect on the autonomic nervous system.Future study is necessary to investigate the long term effect of the physical therapy treatment room environment using microwave diathermy on the autonomic nervous system of the human body.
