When I try to move my gran in bed, her legs are so stiff. Her arms are also stiff. It’s the same if she is asleep or awake.
I always thought arms were floppy if you picked them up when person is asleep.
I was told to try and exercise her legs, which I do, but they are so stiff it is hard to move them.
I agree with the idea of asking for some passive range of motion therapy, once you learn how you can continue on your own.
