膀胱外括約筋の筋電図に関する研究 正常男子の球海綿筋の筋電図について

Abstract

Electromyographic activity of bulbocavernosus muscle was studied in fifteen normal males by percutaneous insertion of bipolar concentric needle electrode. The following points were especially investigated as to normal electromyogram of bulbocavernosus muscle. 1) ζ-S curve 2) Electromyographic activity of bulbocavernosus muscle at the time of full bladder, of micturition and of empty bladder. 3) Electromyographic activity of bulbocavernosus muscle at the time of voluntary contraction. The significance of electromyographic study of bulbocavernosus muscle and the activity of this muscle on urinary continence as well as urination were discussed.
