to ward off ITBS?
How in the world would an outside brace or wrap or outside pressure do anything more than keep pressure onto the band at the very part of the knee, in which everything needs to be opened up, away from that condyle?
In fact, would it not make worse the situation?
My understanding of the mechanics of the IT band is that it tries to turn your femur counter clockwise, toward your midline. You can’t lock that band down from keeping it from doing its job. Or can you? Does that strap do that?
You can even flex your knee and the IT band, come hell or high water, is going to move across the condyle on the knee.
How would a wrap or a brace or a cho pat thing, stop that?
