Objectives : The aim of this study was to investigate the different of yangdorak diagnosis between low back pain patients and medical checkup group. Methods : We analyzed the measurement value of yangdorak on 103 patients with low back pain and 103 medical checkup persons in Korean males from March 1st, 2007 to September 30th, 2008 by using yangdorak(MEDIRA, Neomyth Co., Korea). Results : 1. In comparing results on the yangdorak general mean, low back pain group is statistically significant in comparison with medical checkup group(p<0.001). 2. In comparing results on each meridian yangdorak value, they were statistically significant between two groups(p<0.001). 3. In comparing result on the distance of yangdorak value from the mean, they were statistically significant between two groups at the Bladder-meridian(p<0.05), but not at the Kidney-meridian. Conclusions : This results suggest that yangdorak may be used for a method to objective clinical examination. But further studies are required for a use of practical indicator.

Objectives: The aim of the study was to investigate the potential of Yangdorak diagnosis application against gallstone scanned by Ultrasound diagnosis. Method: For this aim, among 97 patients who had visited Julip Korean Medicine Clinic from July 2016 to June 2023, 30 patients with no gallstone as a control group and 67 patients with gallstone and diagnosed by ultrasonography, were subjected to Yangdorak diagnosis. Then, the changes in Gallbladder Meridian (GB) value as F5 AVE(average of left and right GB value) by Yangdorak were comparatively analyzed between gallstone and non-gallstone groups and statistical significance was evaluated by Tukey's multiple comparison test using Prism software. Results: After all subjects were evaluated by the Yangdorak and ultrasonography to assess the potential of the Yangdorak diagnosis for gallstone, it was noteworthy that the Yangdorak values relevant to F5 AVE of female gallstone group(N=36) were significantly (p<0.001) decreased compared to the control group (N=30), while there was no significance in male gallstone group(N=31). Also, it was recognized significant difference between male and female groups. Conclusion: Based on these results, if the Yangdorak value can be estimated from a decrease with clinical symptom in female patient, it is recommended to follow up the ultrasonography test for diagnosing the gallstone.

Objectives : Functional dyspepsia (FD) is one of the most common gastrointestinal diseases. Nevertheless, there are many unknown mechanisms of autonomic functioning in FD patients. This study was designed to investigate the relationship between FD and biosignals from heart rate variability (HRV) and Yangdorak diagnosis. Methods : 32 patients (22 female, 10 male; mean age 40) and 32 healthy volunteers (21 female, 11 malemean; age 38) participated in this study. First gastrointestinal symptoms rating scale (GSRS) was assessed by questionnaires in both groups to evaluate the types of gastrointestinal symptoms. Second, HRV and Yangdorak diagnosis were measured in both groups. Results : 1. The FD group in this study mainly had the complaint of 'bloating' symptoms. 2. There was statistically no significant difference between Yangdorak (total average and 24 acupoints) and HRV values except logarithmic low-frequency band (lnLF) and total power (TP) in frequency domain. 3. There was statistically no significant relationship between HRV and Yangdorak in either group. However, most Yangdorak values were positively related with some HRV values (low-frequency, low-frequency/high-frequency ratio and high-frequency, etc) in the control group. Conclusions : FD patients had relatively lesser sympathetic domain than healthy subjects, indicated by decreased lnLF and TP. Particularly, there were positive relationships and significant differences between Yangdorak and HRV in young healthy subjects. This suggests that biosignals from HRV may be a useful method that can differentiate FD from healthy state in those of young age.
