I have found over many years that accurate and well performed PF exercises together with anticipatory bracing of the pelvic floor before coughing etc, is the only cure for genuine stress incontinence. However the key word is accurate. Internal assessment is vital to check tone and muscle action. If you cant do that your self, find someone who can and will give you the results. the other factor which may help is strong retraining of the transverse abdominal muscle group which will help to position the PF muscles so that their contraction is effective. good luck and keep us posted
