In order to achieve as high respond rate as possible we decided to restrict the follow-up measurement to the questionnaires: Patient Global Impression of Improvement Scale (PGI-I scale), Fecal Incontinence Severity Index (FISI), St. Marks Incontinence Score (Vaizey) and Fecal Incontinence Quality of Life Scale (FIQL). Questions about further treatment for fecal incontinence since completion of the study and the amount of current pelvic floor muscle exercise will be added.
