If his attempt to get up involves moving an arm or leg off his spot on the floor such that it causes contact that puts an opponent at a disadvantage, then that should be called a foul.

I am JR and I agree.

That case play cited in the old thread gave us that direction that Mike summed up above- "Unless B1 made an effort to trip up or block A1, he/she is entitled to a position on the court, even though if it is momentarily lying on the floor after falling down."

So, it depends.
