Hi Shelee,
Your daughter sounds a lot like Chris. Her study summary is very close to Chris' last one.......except it took Chris 81 min to get to REM and she was there 5 times and her leg movements were 10.4/hr. I also wondered how close the study was to reality, Chris was very well behaved and quiet that night. Normally she is a wild thing in her sleep. The way I see it, even if it was not a typical night's sleep it was still abnormal enough to get her treated and that is the most important thing.
I can tell you that the normal leg movement number is 5 or less/hr. So 6 is not that far off normal. I believe that what they are measuring are things like flexing her foot and big toe wiggling.........not necessarily a big kick and not rolling over. I believe that there have to be 3 movements within a short span of time (seconds) to count as a periodic leg movement.
I don't know what her pulmo will say, I hope that he will agree to let her try cpap and see how thing go. I am glad that you are willing to ask and see, your daughter is very lucky to have such a concerned mom. I hope that you can get everything straightened out before school starts. I can totally understand about kids missing school, Chris missed a day or part of a day each week all year in 1st grade.....
Good Luck tomorrow

Let me know what he says.
