Yes, you are right, and my brother did install such things near loos and steps. Trouble is it gets to the point where you can't fix up such things everywhere, and you can't physically support loved one, like doorways. I don't know what an answer could be - an exoskeleton?

Anyway, best wishes to you and your mom.
