Stress urinary incontinence is a common problem among women of all ages but may resolve with pelvic floor reeducation in many cases. Compliance to a regimen of pelvic floor muscle exercises is poor and many devices have been produced to make exercising these muscles more effective and interesting. This article describes a study in which two such devices -- vaginal cones and pressure biofeedback -- were compared with pelvic floor exercises alone. The results show that there is no statistically significant difference between the three modalities; all treatments produced significant improvement in symptoms and quality of life scores.
