Background or Objectives : The purpose of this study is to review oriental medicine journal that have been utilize Surface EMG in Korea, China, Japan and compare each country's trend in studies. Methods : We investigated studies in relation to surface EMG through 10 articles in Korea from OASIS, 74 articles in China from CAJ, 6 articles in Japan from J-stage. Results : Of 90 articles, 6 articles in Korea, 7 article in China, 6 articles in Japan, totally 19 articles selected. There was no big differences number of articles, type of articles among three countries. There was differences topic of articles, treatment method of articles among three countries. Conclusion : The result of this study could provide useful information of field of Surface EMG is used in Oriental medicine. Studies about Surface EMG performed in different way in Korea, China, Japan.

Background or Objectives : The purpose of this study is to measure surface Electromyography(sEMG) of facial muscles in normal person and to find method for standardizing of sEMG's value. Methods : We measured 3points on face, frontalis muscle($GB_{14}$), zygomaticus muscle($SI_{18}$), orbicularis oris muscle($LI_{19}$) of 40 normal person by sEMG. 40 normal person consist with two groups, each 20 male, 20 female. Average age of subject was $26.50{\pm}4.79$. SEMG instrument QEMG-4 XL was used. After training exercise of facial muscles, sEMG's root mean square value was measured once. Results : 1. In whole experimental group, frontalis muscle's both side average was $78.36{\pm}40.87$, zygomaticus muscle's both side average was $84.70{\pm}49.81$, orbicularis oris's both side average was $104.83{\pm}38.81$. 2. Left side of Frontalis muscle, both side of zygomaticus muscle are high marked in male than female in statistically. 3. In whole experimental group, average of ratio comparing smaller value with bigger value in difference between left side and right side was $19.60{\pm}12.88$ %. 4. Average of asymmetry index(AI) was $11.46{\pm}8.36$ %. orbicularis oris muscle's average of AI had least difference was $8.95{\pm}7.50$ %. zygomaticus muscle's average of AI had most difference was $13.95{\pm}8.90$ %. Conclusions : The result of this study could provide useful information of field of sEMG is used in oriental medicine treatment of facial muscles. To assess efficacy of treatment in facial muscles, we need to standardize facial muscle's sEMG values by using AI, ratio comparing values and etc.
