Do you know how to lift with your legs, not with your back? A bike only weighs 25 lb or so. Your physical therapist should show you how to lift correctly.
There are ways to avoid manually (with your body) lifting the bike. You could use an overhead hoist like the one linked above, hook to the bike then to lift it high enough to clamp into the work stand. You could work on the bike while it was hanging in the hoist, but it would be swinging around which is not ideal.
Or you could bolt the work stand to a hydraulic lift table, and adjust the stand as low as it will go. You'd still need to manually lift the bike a few inches to roll it onto the lowered lift table, then raise it a few inches to clamp it to the stand, then raise the lift table. Cheap lift tables cost about $200.
