My 96-year-old mother is unable to stand/walk and has advanced dementia. Her caregiver is here for 2-3 hours each morning, and transfers her between bed and commode, bed and wheelchair, wheelchair and recliner, returning her to bed before she leaves. The caregiver lifts her, bearing her full weight (my mother is short but weighs about 140). I want to be able to move her from bed to wheelchair in an emergency, but don't know how to do that safely, as she has very limited ability to help at all. (I am a little taller than she is, in good health). We have a gait belt. I don't want to use a lift. I was thinking to have a physical therapist come to evaluate my mother and, if possible, teach me how to do a "dependent transfer" correctly. Does anyone have experience/advice with this?
