Fecal incontinence is defined as an involuntary bowel movement through the anal canal in inadequate time and place. There are different types of therapies for the management of fecal incontinence, being biofeedback therapy one of the most effective techniques. The aim of this study was to evaluate the necessary number of sessions of biofeedback electromyographyc therapy to achieve the maximum sphincteric complex contraction.


Descriptive, retrospective and longitudinal study. 65 patients with fecal incontinence were included. Weekly electromyographyc biofeedback therapies were applied, with a maximum of 6, in which the sphincteric complex contraction was measured. A two ways Friedman analysis was made to determine the significant differences between the sessions.


A total of 65 patients were evaluated for fecal incontinence. The values for pelvic floor contraction were significantly higher in the third session, and did not show any significant difference in posterior sessions.


The maximum contraction of the sphicnteric complex was achieved in the third weekly biofeedback session, without any significant differences in the posterior sessions.
