What is the exact rehabilitation protocol that NASA astronauts complete after being in space for a long time?

I'm especially interested in what rehab an astronaut who takes longer to recover does? I've read Joan Vernikos' book Sitting Kills Moving Heals and she talks about gravity deprivation syndrome and how astronauts need rehab but she doesn't mention the rehab, only things normal healthy people should be doing to use gravity.

Thanks!
