I have no familiarity with braces myself, but I have seen it suggested.
Have a look at this video:

...and some of his others going back two weeks where he suggests Hillary has Parkinson’s.
He theorizes that Hillary could tell that she was going into a “freeze” where she would be unable to move and requested to leave the memorial service asap. The SS was caught off-guard and couldn’t get the Scooby mobile to the pickup point ahead of her, thus she had to briefly wait while they get it ready.
That’s the one I mentioned here:

Go to 5:33 and that’s when the lady to illarys left throws something then grabs her under the armpit.
