How does it work?

Although FSN originated from traditional acupuncture, its theory diverges from classical concepts of meridians, acupoints, Yin-Yang, and Qi. There is also a distinct difference from “dry needling,” which refers to the insertion of a sterile needle into a trigger point for myofascial pain based on Western anatomical and neuro-physiological principles. Manipulation of the FSN needle involves a sweeping motion instead, focusing on reperfusion principles to relieve muscle contraction from trigger points followed by improvement of local circulation.
