Objectives : This study was designed to find out whether there is a correlation between qi-stagnation score and pressure
pain threshold (PPT) on acupuncture point CV17 in burning mouth syndrome (BMS) patients.
Methods : Thirty BMS patients who newly visited Oral Disease Clinic at the Kyung Hee University Korean Medicine
Hospital were surveyed. The subjects were evaluated on age, illness duration, sex, self-assessed severity of BMS, qi-stagnation score, and PPT on 3 acupuncture points (CV17, Rt. SP9, Lt. SP9).
Results : There was significant correlation between age and PPT on CV17 (p=0.005). Therefore, partial correlation analysis
with age as control variable was done, and the result showed significant correlation between qi-stagnation score and PPT on CV17 (p=0.001). Qi-stagnation diagnostic point by PPT on CV17 was suggested as 3.8056 kg/cm2 based on the fact that diagnostic score is 28.50 in the qi-stagnation questionnaire. Furthermore, considering that PPT is effected by age, we could attain qi-stagnation diagnostic equation of PPT on CV17, that is suggested as 0.047×(age)+0.848 kg/cm2. PPT of 3 acupuncture points (CV17, Rt. SP9, Lt. SP9) was compared, and the result showed that PPT was significantly lower on CV17 (w/Rt SP9: p=0.022, w/Lt. SP9: p=0.012). Also, significance and correlation coefficient with qi-stagnation were higher on CV17 (p <0.001, r=-0.620) than Rt. SP9 (p=0.023, r=-0.413) or Lt. SP9 (p=0.014, r=-0.444).
Conclusions : The result of this study suggested that PPT on CV17, measured quantitatively by algometer, had a strong
correlation with qi-stagnation score in BMS patients. Therefore, the study showed that CV17 can be a useful acupuncture point in diagnosing qi-stagnation by measuring PPT in BMS patients.
