I think it's wonderful that you're on here trying to find some help for your girlfriend.
Is she in pain? Is she able to get around the house pretty well? Is she working?
There is a thread on less stress on your back around the house that might have some tips she could use. You can copy/paste: [url]http://www.healthboards.com/boards/showthread.php?t=468037&highlight=less+s tress+on+back+around+the+house[/url]
Also, even though she hasn't had surgery, she might find some helpful tips in the thread at the top of the page called "post surgery tips." If you don't see it, you can copy/paste it: [url]http://www.healthboards.com/boards/showthread.php?t=19953[/url]
One huge help to her would be a grabber tool. It's about 2 1/2 or 3 feet long and has a handle at one end and a little gripping claw at the other end. For someone who can't bend, the grabber tool is priceless! They run around $30 and can be found at medical supply stores and at many pharmacies with the durable medical supplies. If she doesn't have one, you could get her one and put a great big bow on it. She might think it's silly at first, but after only one day, she'll be carrying it with her everywhere! And you'll score many brownie points for getting it for her!
I wish you both the best!
