That pump thingy pumps out the extender thingy that is attached to the bottom black strap, and that stretches the spine between the two black straps. Got all that?

Missy thinks it is a fine device!
I'm going to Haley's house to scrapbook and leaving Missy in charge of therapy.
Have fun, y'all! I'm outta here...
