초록

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(GB14), zygomaticus muscle(SI18), orbicularis oris muscle(LI19) 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±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±40.87, zygomaticus muscle's both side average was 84.70±49.81, orbicularis oris's both side average was 104.83±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±12.88 %.
4. Average of asymmetry index(AI) was 11.46±8.36 %. orbicularis oris muscle's average of AI had least difference was 8.95±7.50 %. zygomaticus muscle's average of AI had most difference was 13.95±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.
