    The machine we used for testing was a biodex machine with a torso rotational attachment. You are correct that isometric is stationary. The Biodex has a dynamometer that can measure and control many...

    It is indeed. It's full of technical and logistical and budgetary issues. But its power and possibilities are pretty impressive.

    Regarding muscle strength, you're correct in that it is pretty difficult to assess this. What makes it even more complicated is that muscles on both sides of the spine participate in moving the spine...

    No, don't derotate. Don't do anything except try to make sure the postures are the same. When I was saying I wanted to see you in a true neutral, that was more the researcher talking, i.e. let's see...

    It's difficult to tell how much your pelvis is rotated because the x-rays don't show the full pelvis. You mentioned that you might get another x-ray at the chiro. If you do, see if they'll open up...

    Yes, N=Newtons. And yes, it isn't much weight at all. I believe Stokes was the one who published this. While it is a very small amount of weight, remember that these studies were done on cadaver...

    Yes, the SEAS researchers are MD's and PhD's. I would also assume they have some type of physiotherapists working with them as well. Stephano Negrini is one of the main guys (an MD or PhD). He's big...

    The same basic percentages would probably be the same. These certainly wouldn't change a large amount if the AIS pattern is different. I would also say that, any change seen, would most likely be a...

    Not a whole lot more to add. There are a handful of studies (although not many) that have looked at paraspinal atrophy during brace wear. I'm not sure specifically what type of brace or if it was...

    That's certainly possible. But the study they used is pretty big. They screened over 1 million kids. I suppose one from Denmark would be the most appropriate. But their reference isn't an obscure...

    Whenever I hear about MRI machines breaking or 'going down'. This is usually what I think happens.

    It's certainly possible that it plays a role in some way. It plays a role in other orthopedic issues from the low back down to the ankle.
