I had my procedure done last oct in RI, I believe i was patient number 20 for the practice and have been back for 3 follow up ultra sounds. The staff there is wonderful. I have good flow on both sides still and have seen wonderful improvements.
I did physical therapy after the procedure and went with my neuros blessing. He has been impressed with my improvements. Just two weeks ago he gave me his blessing to go off the disease modifying drugs, provided I don't have any flare ups.
Also had an MRI which showed no active lesions right now and no change since 2009. Good luck. You will be in good hands.
