Zhonghua Fu runs a successful pain clinic in Nanjing, China affiliated with Nanjing University of Chinese Medicine. At the FSN clinic for pain medicine, FSN is used as the sole means to treat musculoskeletal disorders and some chronic benign visceral disorders.
Fu originally trained as a TCM doctor, completing his masters in acupuncture. While practicing and teaching traditional acupuncture in Guangzhou, he realized that several innovations were needed to improve and accelerate the acupuncture effect. Because some techniques for painful problems in the ancient HUANGDI INTERNAL CLASSIC were punctured obliquely surrounding some painful spots, Fu thought inserting horizonally is a good choice, and then FSN came into being after a number of trials.
After completing his Ph.D, Fu conducted research in his lab for 2 years on arthritic rats. During these trials, when the needle was inserted into the local point of sensitivity, there were no profound changes in VAS and Range of Movements. Notable changes in VAS and Range of Movements were observed however when the needle was inserted parallel to the skin surface.
