Someone says they think she has lost the ability to react when she starts to fall. She is coming out of rehab & will be moving back into the house she is renting. They say they are releasing her from rehab because she is safe to be on her own! She uses a walker, but it won't fit into the bathroom so she was using a cane & holding onto the sink, a bar attached to the side of the tub, & then the arms on the toilet. Not sure she will be safe. Right now we are hiring aides since I can't be there with her all of the time. Any ideas as to why she might be falling or ways to help?
