It's no big deal if she has been in hospital for 4-5 days she will have had some rest. The hospital usually supplies aids to help people living alone, things to help you put your socks on with, walking sticks, crutches, picking-up tongs, special toilet seats and chairs. They check out your bed to see it isn't too high or low. A special chair to sit in the kitchen to do the washing up or making dinner, and a trolley with wheels to carry cups and plates into the room. They even took time to supervise me washing myself at the bathroom sink as you cannot take a bath or shower for a while, unless you have a wet room shower. It is of course better to have help, but as long as she rests and does her exercises she should be OK. All she really needs is someone to call in to see she is OK every day.
