Analysis of Professor Yang Jingfeng’s Academic Experience in Treating Pediatric Multiple Tic Disorder

Abstract

MTDs is characterized by involuntary facial and eyelid muscle twitches in children, often accompanied by emotional disturbances. In traditional Chinese medicine, this condition corresponds to syndromes such as chi zong (convulsions) and chronic infantaile convulsion. Professor Yang Jingfeng holds that the internal cause of this disease lies in congenital deficiency of primordial essence, spleen deficiency and liver qi depression leading to insufficiency of nutrient-defense qi and exterior instability. The core pathogenesis is summarized as taiyang meridian and yangming meridian invaded by pathogenic factors, which trigger liver wind.” Clinically, treatment first adopts the principle of “remove wind and relieve the exterior, calming wind and relieving spasms” After symptom relief, the therapeutic focus shifts to “tonify the spleen and kidney consolidating the root, and strengthen the body.” Professor Yang often employs modified Gegen Tang (Radix Puerariae decoction) combined with Qianzheng San, which has demonstrated remarkable clinical efficacy.
