I mean to educate the different types of fibres responsible for each type of contraction. Fast twitch fibres are activated for instance in a quick reaction type situation where for example you cough or sneeze and have a sudden increase in intra-abdominal pressure which needs to be counter balanced. So this exercise I would and very politely ask the patient to imagine that they were about to pass wind and wanted to prevent this from happening!I would then ask them to squeeze the muscles around the back passage and take the contraction all the way under the pelvis to the front to the muscles which stop you passing water. I would then tell them they should feel everything lifting up inside. i would double check that they are not holding their breath. I would ask them to do this exercise squeezing up and then letting go over a count of two repeating 10 times then do 3 sets or so. Next the slow twitch fibres responsible for maintaining fluid in the bladder over the course of the day without the immediate sensation of wanting to void so these are the endurance fibres if you like. This is the same action but this time hold the contraction say for 5 secs. The length of time your patient will be able to hold the contraction will vary depending on their strength. If they are struggling, start with 2 seconds then build up but they should always be able to feel the contraction release if no they have lost it long ago or maybe don't get it. Work towards holding for 10 or 15 seconds with 10 repetitions Also get them to try the exercises in different positions remembering that if the patient is standing then they are having to work against gravity and the exercise will be harder. On the contrary some women find this position better since they get more feedback from the muscles. You can try crook or side lying to start with. try to combine the pelvic floor action with deep abdominal contraction and breathing is very important. Some women really struggle to identify the pelvic floor and whether it is working or not I normally explain it is like a hammock holding all the abdominal organs so they can see how it can become a problem, also that if any of these organs are removed as in hysterectomy it can alter the stabilty.
hope this helps!
