There are different types of biofeedback. I have used it to strenghten my sphincter muscles after they were damaged in a surgery. It can also be helpful for peopel who need to better learn how to empty more effectively, etc. This is often done at a pelvic floor center or similar.
Biofeedback can also be used to help you better learn how to manage pain, stress, and other things. This may or may not be done in a pelvic floor center, but coiuld be done in a pain clinic or a psychologists office.
Biofeedback is not magic or a treatment they DO TO YOU. Rather it is a treatment that uses equipment to help you understand how your own body systems (breathing, muscles, brain waves) are responding to your own thoughts and/or actions-depending on the type of biofeedback you are doing). You can start to learn, when I do/think X this is how my body responds or when I do/think Y I get some different reaction by my body. Then you can gain more conscious control to do/think the the way that your body best gives you the desired reaction.
I am waiting for insurance authorization to do another round of biofeedback for sphincter training as it has been many many years since I did it before. I don't think I will get much additional gain from it, but I did see some positive results the first time i did it, so it may be worth a try.
