User blog:CutePets95/Something I need to know about Cerebral Palsey

I just started my page on Madi and I have no idea what's an item she uses is called to help her walk. I can try and give an accurate description:
 * Made of metal
 * Has wheels
 * Used for people with Cerebral Palsy
 * Helps with walking
 * Consisted of metal bars
 * Has no top, bottom or back

Does any of you know what it's called? It would help a lot.

By the way, before anyone asks why I'm asking for help, it's pretty useless if I don't know what I'm talking about.
