NCT01130870

Brief Summary

The purpose of this study is to determine if subsensory stimulation (amplitude) will maintain same continence in patients treated with Sacral Nerve Stimulation (SNS) for faecal incontinence as stimulation with amplitude at sensory threshold.

Outcome Measures

Primary Outcomes (1)

  • Number of incontinence episodes Assess number of incontinence episodes.

    Assess number of incontinence episodes, by means of bowel habit diary. Four week bowel habit diary will be evaluated three times during the twelve-week protocol perioed.

    Will be assessed every four weeks during a twelve-week period

Secondary Outcomes (2)

  • Assess changes in anorectal volume and pressure with different amplitude.

    Will be assessed every four weeks during a twelve-week period

  • Assess Quality of life after decrease in stimulation amplitude.

    Will be assessed every four weeks during a twelve-week period
