Pelvic floor disorder anyone?

Working with biofeedback will be a long path. First improvements you may get after few weeks or months, but you should keep doing it for rest of your life to maintain strong pelvic floor muscles. It is like with any sport, when you stop doing it, you get weak.

Try to avoid elevated abdominal pressure as much as possible. Abdominal pressure happens when you contract abdominal muscles and diaphragm. In this case abdominal space become smaller and pressure elevates. Because your pelvic floor is too weak to resist, pressure push your pelvic organs out. You can see it on schematic picture.

I recommend you to learn some basic anatomy of pelvis and pelvic floor muscles to make  your work with biofeedback  more efficient. You should understand that when you work with your vaginal muscles, only bottom third of vagina is contracted by pelvic floor muscles. Top 2/3 of vagina has no  sceletal muscles, so you can't contract it by pelvic muscles. Top 2/3 are "contracted" by abdominal pressure. It is not work of vaginal muscles, but just intraabdominal pressure that squeeze it from outside.

Very important is to choose good biofeedback device, that give you positive feedback when you work with pelvic floor, and gives you no feedback when you work with abdominal muscles or elevate intraabdominal pressure. I would not recommend to use devices that use EMG activity. EMG based biofeedback don’t show you if are you elevating pressure or not. Because pelvic floor is weak, all beginners can’t control their pelvic floor and other muscles properly yet and  involve other muscles around, therefore increasing abdominal pressure. This is very dangerous, because intraabdominal  pressure is harmful for weak pelvic floor, because it pushing out pelvic organs and increase prolapsus.  

 Very good biofeedback device is ball-shaped thing inside vagina with laser stick outside. When you work with your pelvic floor, laser pointer goes down. If you contract abdominal muscles and increase pressure, laser pointer just not going down. You measure results by laser pointer amplitude in cm. This device teaches you to work with pelvic floor muscles without involving intraabdominal pressure. This  device is also good for exercising at home, because it is simple.

So, my advices are (1) learn about pelvic floor, where are muscles that you should contract, how intraabdominal pressure works and how to avoid it. How to work with your pelvic floor rest of the day in daily activities. (2) Choose good biofeedback device and specialist, who can explain you anatomy and how to work with your body.
