Bill is classed as a 'faller', but that is because his balance is 'shot' through the vascular Parkinsons/dementia. He needs help standing, but will manage a few steps once he has his balance. As far as leaning the house is concerned - wheelchair. His lack of balance has stopped him using his buggy, so that leaves Ann propulsion, which is hard.
Luckily he is not bedridden, but none of us has a crystal ball have we???

My husband, Bud, was in mid stage and suddenly began falling and over a two week period, could not walk anymore. He is bedfast now.
