EPISODE TRANSCRIPTION CHRISTINA PREVETT Hello everyone and welcome to the PT on ICE daily show. My name is Christina Prevett and I am one of our lead faculty in our pelvic health division and I'm coming to you from a cottage on my 35th birthday because I had a Wonderful husband who surprised me but that does not mean that I'm not gonna get excited talking about all things pelvic health so We had a really interesting conversation come up over the last several weeks, and it's funny because it's come up in a variety of different circles around defining normal. What is normal when it comes from a pelvic health perspective? Because when we are trying to make diagnoses of different conditions, urinary incontinence, pelvic organ prolapse, diastasis recti, we have to know what the realm of normal is so that we know when we deviate from it. And so we had a question come up in our app about, what is the amount of normal voiding, the number of normal voiding episodes that an individual should have during the day? Because some of our literature says 5 to 8, and some of it says 8 to 13. And then if you leak a little bit when you're really tired, does that actually consider you to have a condition? Do you have urinary incontinence? If you have a kind of a spasm in your shoulder, you wouldn't say that your shoulder was injured, but you would say that you have urinary incontinence. And it's such an interesting question, and I kinda wanna dive into it a little bit today. So last week, as many of you know, I'm a postdoctoral research fellow at the University of Alberta. And so what I am looking at in my research, I am an interventional researcher, specifically looking at resistance training and its impact on health. And what my studies are looking at specifically right now is on resistance training in pregnancy and its impact with pelvic floor dysfunction. What I was doing was I was learning from physiology researchers. I was looking at individuals who were looking at pelvic floor assessment and measurement. And up in Ottawa, I was at Linda McLean's lab, they are doing data taking on what is normal force production of the pelvic floor and what are things that we can expect to see as differences in the pelvic floor on ultrasound, on EMG force activation, and on dynamometry, which is force production. in a younger cohort of individuals and an older cohort of individuals. And this sparked a lot of conversations because we know that with age, for example, pelvic floor dysfunction goes up, but what are normal wrinkles on the inside of the pelvis? And what are things that we would consider abnormal or needing to seek some intervention for? So I'm gonna try and take you through a couple of different examples in the literature of what we know, what we don't know, and what we have to acknowledge is just areas of gray. So we're gonna talk about the bladder first. So some of our literature is saying, you know, five to eight Ps during the day is normal. Some individuals have pulled that up to eight to 13 as a top end of normal. And then some people will say that you shouldn't ever have to pee at night, or it should be rare, like you shouldn't be getting up consistently to pee at night. And others say that that is true if you're under the age of 65. But if you're over the age of 65, getting up once to pee is considered within the realm of normal. So let's talk about why there is that variability. When we are looking at data sets and we are trying to incur where that normal distribution is. So we think we have an average if it's normally distributed and 95% or 97.5% of our data is going to swing within plus or minus two standard deviations of the mean. And I'm getting kind of in the weeds of statistics here, but that's kind of our normal distribution. And our P of less than 0.05 on a two-tailed test are the ones that are below that two standard deviations on either side. And what that's saying is like when we have this big group of individuals who are ...
