WELCOME to the forum! You'll love this place

How exciting that you're gonna do the trial soon!
There are SO many folks here who comprehend what this is all about, so I hope you'll make yerself at home, and no doubt we'll learn from you as well.

I had to Google TLSO brace , as I have never heard of it. (See! you already taught me something!) I guess it's also known as the 'Boston Brace'. It looks like quite the contraption!
Maybe someone here is familiar with this and I'm sure you'll get lots of replies in no time...

It's great to have you!
