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
Study Arms (3)
Sensory threshold - Amplitude
ACTIVE COMPARATORStimulation amplitude set at sensory threshold.
25% below sensory threshold - Amplitude
EXPERIMENTALStimulation amplitude 75% of sensory threshold.
50% below sensory threshold - Amplitude
EXPERIMENTALStimulation with amplitude set 50% below sensory threshold
Interventions
Sacral nerve stimulation with amplitude (sensory threshold), Frequency 14 Hz and pulse width 210 mic.sec.
Sacral nerve stimulation with amplitude (75% of sensory threshold), Frequency 14 Hz and pulse width 210 mic.sec.
Sacral nerve stimulation with amplitude (50% of sensory threshold), Frequency 14 Hz and pulse width 210 mic.sec.
