I know a lady who is 90, blind and probably in middle stage Alzheimers, actually has these from her last trip to the hospital. She likes them so much for her "in between beauty shop visits" that she actually had her daughter purchase some. I personally haven't used them but have first hand experience with a patient who adores them.
Depending on your grandmothers prognosis, she may be eligible for Hospice. No. I'm not saying your beloved is going to croak soon, BUT hospice can help provide, cover costs for DME's (durable medical equipment) that could make your life and your grandma's life easier. A shower chair to help aid in energy preservation during a real shower. Or a riser seat for a commode helps out leaps and bounds.
Also, if she doesn't have issues with incontinence needing briefs, if you don't have one, a special seat for ease of bathroom breaks in bed, is also available, it helps so her hips don't flex as much.
Word to the wise though, if she is given the go for upright bi-pedal movement make sure she does it, or she could end up with pneumonia quickly, resulting in more Hospital time
