Everyone knows Zod loves to have people knee lbefore him. "Kneel before Zod" is his most popular line. I know he is a villian and all but surely he wouldn't even stoop this low. If someone rolled out Stephen Hawking in front of him I would asume he would give the guy a pass, just as long as he is willing to be a slave like all the other humans he wants to control.
I supose it might be more of grey issue with old people. He would proably make them kneel but I am sure he would let younger people kind of help them up afterwards if they can't do it by themselves. As for people who have just had surgery and can't get up I think he would still require them to kneel at some point. He would just get one of his goons to keep tabs on their recovery time and come back when it is more convient for them.
