表面筋電図では筋肉内の複数の運動単位で生じた活動電位による干渉電位が得られる．そこで表面筋電図上で伝播した波形の特徴を見ることによって，筋収縮特性の考察のための新たな指標となることが考えられる．本研究では，隣り合った電極から導出した筋電図により伝播波形を抽出し，その速度の導出方法の比較と検討及び，伝播波形の特徴の解析を行った．%In surface electromyogram, interference potentials of action potentials which are occurred by multi-motor units in muscle are recorded. By observing characteristics of propagating waves in electromyogram, the characteristics can be set as new indicators for considering features of muscle construction.In this study, propagating waves were extracted from electromyogram by using several sets of adjacent electrods, and derivation methods of conduction velocity of the waves were investigated and compared. In addition, characteristics of the propagating waves were analyzed.
