Most admissions offices will probably tell you no, as unfortunate as that is from an admissions chances standpoint. See thread linked above. I will say, when I was applying I was pretty ripped that all my hours as a pt didn't count (as you will notice in the above thread), but now looking back I totally see where they are coming from.
For one thing, it's really not fair to give any extra points in the admissions process because someone happened to require PT treatment whereas other applicants didn't. Schools have to strive to have a more fair and objective way of comparing applicants. People applying to medical school don't get to count all the times they've had a doctor's appointment as "shadowing". If it were true that having been a pt in PT throughout your life has made you aware of what being a PT is like, it would also follow that practically everyone in the population has a good idea what being a physician is really like - we've all been to the doctor throughout our lives!
But that's not how it is - you only see one segment of the professional's daily work life as a pt, whereas the goal of observation hours (assuming the school requires them) is for you to see the profession you are entering from the other side of the fence, through the professional's eyes. So though I was irritated when I was applying, I can see now how the experience you get from watching several different PTs treat lots of different pts for say 100 hours and having them explain a bit of what they are doing and thinking is very different than what you get from attending your own therapy sessions with your own PT. The experience of having seen what PT is like as a patient (especially if you have been treated in different settings) is very, very valuable, it just doesn't accomplish the same goal as observation hours.
Also, only things you've done while in college can be put on PT school applications, so any experience from before that is just a good interview talking point. And to be honest, most faculty/interviewers have heard applicants tell the story about how "their experience as a pt in PT benefited them soooooo much and it just really inspired them to go into the field" ten thousand times over, so you don't win a lot of brownie points for that kind of story, even if it may be true.
