Introduction: Urinary incontinence is a condition that affects most women in her adult life; it is considered a public health problem and has a high negative impact on the quality of life. Physical therapy is considered as the first treatment option for this disease, these treatments are done with pelvic floor muscles exercises (kinesiotherapy) with or without the use of other resources such as biofeedback, electrical stimulation and vaginal cones. Rationale: The protocols used in the various studies on the treatment of urinary incontinence are made with only one type of therapy and have no change in the intensity of the exercises. The "Active Perineal Rehabilitation" protocol uses kinesiotherapy with biofeedback, electrical stimulation, vaginal cones and home exercises; it consists of 14 individual sessions that gradually evolve the intensity of exercises. Objective: To assess the scientific validity of "Active Perineal Rehabilitation" protocol for the treatment of urinary incontinence. Methodology: A multicenter, prospective clinical trial, controlled and randomized, the sample will be divided into a study group that will be treated with the Active Perineal Rehabilitation protocol, and a control group will be treated with the protocol already widely used.

Urinary incontinence is defined as an involuntary loss of urine, the World Health Organization (WHO) considers it is a public health problem having a negative impact on the quality of life of such patients. Its prevalence ranges from 3% to 55%, it is difficult to have a right number because different definitions used and the range age of the population studied. Its more common type is stress urinary incontinence (SUI), the involuntary loss of urine on exertion, coughing or sneezing.

In the old days, those pathologies were seen as a natural consequence of aging, making people adapt to the changes imposed by them. Modern society and the increase of life expectancy made people care more about their quality of life and well-being, making them search for treatments to those pathologies.

The International Federation of Gynecology and Obstetrics, International Continence Society, as well the most of national societies of gynecology and urology, deliberate that physiotherapy is the first option to urinary incontinence treatment. Perineal rehabilitation aims increase pelvic floor muscle strength, to intensify urethral closure.

Perineal rehabilitation is showing to be an efficient treatment to urinary incontinence, studies show that rate cure is between 28 to 84%, this large interval is because different techniques and different assessments in each study.The treatments used in perineal rehabilitation are kinesiotherapy (pelvic floor muscle exercises), with or without biofeedback, electrical stimulation and vaginal cones.

Although there are several studies about physical therapy to urinary incontinence treatment, there are not studies that use more than one of these techniques. Other problem is the fact that the protocols used in these studies start and finish with the same exercises intensity, there is no evolution in the treatment. It can be observed in the literature review made by Hay-Smith, 2012 and Margarida Ferreira e Paula Santos, 2011.

The "Active Perineal Rehabilitation" (APR) protocol uses perineal kinesiotherapy with biofeedback, electrical stimulation, vaginal cones and home exercises, its intensity increase session by session, like is recommended by American College of Sports Medicine. This protocol is unique and innovative to urinary incontinence treatment.
