My mom used to walk a lot. Just within the last yr. Now I can't get her to walk down the hall in her assisted living residence. says her legs hurt too much. she sits, or lays around most of the time. I try to take her out shopping, where she has to walk. missed a bus trip the other day because she couldn't make it up the steps of the bus (3 of the).. and refused to be lifted in a wheel chair. how do I get her moving again? or is a wheel chair gonna be the answer?
