Mom broke her hip and due to heart issues could not have surgery to repair. This was Aug. 2018. Still today she believes she can take trash to corner, pick up tree brush and put onto truck bed, wash clothes in basement, etc. I've tried to explain she is not able to walk and can't yet stand on her own. I've practiced standing with a walker but she can only stand about 15 seconds. Two orthop. doctors have felt she is wheelchair and bed bound. Physical therapy didn't help just caused more pain. She asks these questions every day over and over insisting she can walk and that I'm the one who says she can't. So I try again for her to show me she can walk and again she can't. Anyone else have an idea how to get through....and yes she does have some dementia.
Cajoling her may be the only way to keep her content. I used to say that things were in progress, doctor was going to be doing an evaluation, insurance needed some forms, etc. But, I did it with a smile and said it was good news. So, she was happy to have the good news. HOWEVER, if she really believes she can walk, I'd try to supervise her at all times, so she doesn't fall down and injure herself. Telling her to stay in bed or wheelchair, won't likely work, because she will likely forget what you said. Even if you say it every hour, she may have forgotten it in a few minutes, so, these comforts may need to be repeated very often.
I will say that eventually, she may likely progress from this stage and no longer ask about walking.
