Stress incontinence is the involuntary leakage of small amounts of urine through the urethra due to physical activities, laughing, coughing or sneezing. This is the most common type of urinary incontinence and is caused by the weakening of the pelvic floor muscles. The pelvic floor forms a functional and anatomical unit that supports the visceral organs in the pelvis. Stress incontinence occurs due to congenital or acquired damage of organs statics in the small pelvis, which leads to loss of support to the vesicouretral segment. Considering the severity of the symptoms there are three levels of clinical manifestation of stress incontinence. Physiotherapy interventions in stress incontinence include exercises for the pelvic floor muscles, biofeedback, functional electrostimulation, magnetic inervation, application of vaginal cones and pessaries and bladder training. Physiotherapy goals in treating stress incontinence are to increase the strenght, endurance, function and coordination of pelvic floor muscles, gaining awareness and control, and improving pelvic floor muscles response on the increase of intraabdominal pressure.
