I do not use a walker or cane because it promotes a bent over back. I use a walking stick in the yard. I do not use a call button around my neck because I am not a cow!. My phone has a call button and I can easily dial 911 which I have done in the past because I live alone. I do stretching exercises to try to rebuild strength and balance.
Using a walker at this point would be giving up in improving my strength and ability. I won't do that. Dorisena
