I think it's about like any treatment for MS.....it's success depends on the individual who's receiving it. I think the percentage of people with MS who have the blockage was 56%....I might be wrong.....so this procedure just might help you if you have this blockage.
I wonder if this improvement lasts indefinitely? There hasn't been enough research or followup on people who've had this.....but there really hasn't been enough time elapsed to study it.
Didn't Wheelchair Komakazi have this done? Seems like he wrote about his procedure.
Edit to Add: I found the thread about Marc:
