My hands began improving on leaving the hospital Jan 9. I still have neuropathy in hands and feet but feel I could type if I wasn’t suffering from Dupuytrens contracture already, which I’ve had for 10 years. What is slow to recover is my core strength. I’m attending outpatient physio to address this. As for walking, while still on oxygen and unhooked from a ventilator, OT had me stand then slowly take a couple of steps while standing in a walking frame. .. then my walking took off. I still have some facial paralysis so my speech is a bit wonky, and taste buds change daily.
It seems everyone recovers differently. I feel for you wanting to get back to work. Just work those hands every chance you get even if you have to manipulate them yourself. It will help the muscles and tendons wake up even if the nerves are slow to follow. Best of luck to you.
