In order for the processes of urination and defecation to go smoothly, the various muscles within the pelvis need to act in a coordinated manner. In some cases, the muscles contract when they should be relaxing, or the muscles do not relax sufficiently to facilitate coordinated movement. Problems with the pelvic floor muscles can lead to urinary difficulties and bowel dysfunction. PFD is experienced by both men and women.
Other devices. There are various other devices that are sold to help with pelvic floor exercises. Basically, they all rely on placing the device inside the vagina with the aim of helping the pelvic muscles to exercise and squeeze. There is little research evidence to show how well these devices work. It is best to get the advice from a continence advisor or physiotherapist before using any. One general point is that if you use one, it should be in addition to, not instead of, the standard pelvic floor exercises described above.
