After my first major attack of MAJOR vertigo I went through over 6 months of physical therapy to retrain my balance and eyesight. Prior to that, I had been flat on my back in bed for 6 months. I credit physical therapy with giving me (most of) my life back. Without it I don't think I would have ever gotten out of bed again. I am close to normal now. Not quite normal, but pretty good. My scores on the weird machine with the moving floor went from 16% to 80% over 6 months.
