Scalp Acupuncture treatment is a clinically effective acupuncture method, and previous researches about it's therapeutic mechanics were all centered on anatomic analysis. This study has revealed the therapeutic mechanics of Flying Needle Manuver of Scalp Acupuncture through analysis on its unique biomechanics combined with physiology and pathology. Flying Needle Manuver can produces piezoelectric effect,thus it induces extensive biological and clinical therapeutic effect.
