Both focused and radial extracorporeal shock wave had been proved to treat carpal tunnel syndrome by several studies. However, there was no study comparing these two methods. Considering different mechanisms and costs, this randomized comparative trial would be conducted to compare the efficacy of focused and radial extracorporeal shock wave for carpal tunnel syndrome.
