“…Earlier, Denny Brown and Robertson (1933) pointed out that defecation alternates with micturition in the normal, but in spinal man both acts occur simultaneously. Several other studies (Floyd & Walls, 1953;Kawakami, 1954;Taverner & Smiddy, 1969) have also shown that any increase in intra-abdominal pressure in normal persons pro duces bursts of motor activity in the pelvic diaphragm (levator ani) and in the anal sphincter muscles. Therefore, there is potential difficulty in the interpretation of the results of CMG-anal EMG studies in normal persons when there is a rise in intra-abdominal pressure during urodynamic studies.…”

“…Johansson [9] beschrieb 1991 seine Erfahrungen mit einer monopolaren "Wire"-Elektrode, die der moderne sehr dünne Ableger der von Beck [5] und Taverner et al [22] verwendeten "Steel Needle Electrode" ist. Die "Single-fibre"-Elektromyographie mit den sehr dünnen (25 µm) Elektroden [14] Möglichkeit von Störeinflüssen benachbarter Muskeln, z.…”
