A Roller Wheel or 7 Star or Plum Blossom are 3 different devices that do essentially the same thing and are used to do the same thing. They all stimulate the superficial nerves just under the skin. By doing that, you increase the propagation of nerve signals to the brain and by doing that you can help treat numbness. It works by the “Gate Control Theory” developed by Melzak and Wall. It’s just a unique application developed by the Chinese by observation of it’s effect even before that control theory was developed.
