My Grandmother, who is 80 and lives with us, recently had a complete knee replacement. She needs the other one replaced too but the Dr. said she needs to build some quad muscles before he'll do the next surgery. My Grandmother doesn't do nearly the physical therapy that she is supposed to be, and she's not senile, but on this topic she acts it. "I am doing it" (when she's not and she knows it!). I'm going to go crazy if I keep nagging her about it. Do you have tips? Are their pedometers that talk to you? Special watchers that have 12 alarms that can drive her crazy every hour and tell her to keep moving? Any way of tracking that's worked for anyone? Thanks for any input... she wants to be healthy (at least she says she does) and I want to help her, but I don't want to kill our relationship in the process
