Behavioural therapy (BT) is the first-line treatment for urinary incontinence including idiopathic overactive bladder (iOAB) syndrome. It requires education of the actively participated patient as well as time and effort from the clinician. However, the most effective method for patient education in BT remains unclear. Researchers designed a randomized controlled trial to compare effectiveness of 3 different methods of patient education in BT for women with overactive bladder.
