Physiotherapy in Stress Urinary Incontinence

The goal of this randomized controlled trial is to evaluate and compare the effects of functional magnetic stimulation and pelvic floor muscle training on pelvic floor muscle function, urinary incontinence symptoms and quality of life in women with stress urinary incontinence. The main questions it aims to answer are: * What is the effect of functional magnetic stimulation on pelvic floor muscle function, symptoms of urinary incontinence and quality of life in women with stress urinary incontinence? * What is the effect of pelvic floor muscle training program on pelvic floor muscle function, symptoms of urinary incontinence and quality of life in women with stress urinary incontinence? * Which intervention is more effective - functional magnetic stimulation or pelvic floor muscle training program? Participants will be evaluated before and after the intervention with the following methods: * International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF); * Incontinence Impact Questionnaire-Short Form (IIQ-7); * Pelvic floor muscle strength and endurance will be assessed with a "Pelvexiser" perineometer.
