My 81 year old mother has Parkinson's. She used to be able to shuffle around with her walker and get herself to the bathroom, kitchen, etc.. After a fall last October, which caused a pinched nerve in her back, she has been unable to walk. She moved in with me at that point and needs help doing everything. She has a wheelchair but can't really move herself around in it because her arms aren't strong enough. I'm wondering if an electric mobility chair would be a good option. I would like her to be able to at least move around the house and have some mobility. And do some things for herself. Any input would be appreciated. Thanks.
