I have MS and my feet have tingled for 15 years or more. Recently I saw a physical therapist who has a Powerplate in his office. Since he has been treating me and I have used the Power Plate 10 speed(vibration therapy) I can now feel my toes again and I balance better. Additionally, I am able to ride my 10 speed again. 1st time in 4 years! I believe in the therapy. More research into the ms side needs to be done.
