A method is presented for the identification and analysis of constipation due to difficult evacuation of rectal content. This condition--which has not been elucidated by former techniques--was identified in 5 out of the 19 constipated patients by this new method. Disturbed defecation was characterized by prolonged evacuation of the simulated stool and the greater work performed during this process. The cause of this phenomenon was the paradox movement of the pelvic floor, i.e. contraction instead of relaxation. The results' highlight: the excessive straining can induce a neuromuscular damage to the pelvic floor. The clinical importance of this method lies in the clarification of the principle, that the therapy of this condition must be initiated as early as possible.
