Dear Barb: I had a pallidotomy at USC in July of last year. Immediately after and for the next 5 days, I was dancing- I felt light and agile, the best I've felt in 10 years. Then I began to notice my tremors coming back on my right side (I had a left pallidotomy) and my agility gradually decreased. However, the rigidity on my right side continues to be about 20% of what it was pre-op with virtually no cogwheeling. But for those five glorious days, it seemed as though all the neural pathways that govern movement, that pattern behavior, that allow automatic action and response, were up and functioning. I guess it's reassuring to know that the old circuits are still there...if I could just get some "juice" in them. Best regards, Marion
