In my extensive conversations with Robert Rogers, I realize that he defines recovery much the same as Tricia. That leaves a broad range of interpretations for what is happening to various people. I find a more narrow definition suits my way of thinking. I think that a person has recovered when they no longer have any manifestations of whatever it is they recovering from. Using that definition, I don't believe that any of us will recover from Parkinson's until at least the cause is known or the causes are known and treatments have been verified to actually rid the person of the disease. The cycling program that I'm associated with, PFP, has certainly brought relief to hundreds of people, perhaps thousands, but there is no statement that this is a cure. Although I am still diagnosed as being at level one, I can certainly feel changes to my body that I relate to PD. Nonetheless I cycle on. Whatever helps.
