Anal incontinence (AI) is used to englobe the involuntary loss of both fecal material and gases, which can help to improve quality of life. Based on these experiences objectives were drawn: to evaluate the effectiveness of radiofrequency and it's influence on quality of life of patients with anal incontinence, to correlate the anal incontinence severity and to evaluate a sexual function and to verify an influence with radiofrequency treatment. It is a blind randomized clinical trial. For the collection of data it was used a fecal quality of life questionnaire (FIQL). The questionnaire assess the severity of Anal Incontinence (FISI), the degree of patient's satisfaction using a five-point scale (Likert) and a visual analogue EVA scale). It was divided in two groups, in one group it was used radiofrequency and pelvic exercises and in the other turned off radiofrequency (heated glycerin) and pelvic exercises. It was accomplished in eight sections. As a result, it is expected the efficiency of the treatment of radiofrequency in the quality of life, in sexual function and in it's severity.
