The fenrou zhijian theory in The Inner Canon of Huangdi and the stratified treatment of painful bi syndrome of meridian tendons

Abstract

The fenrou zhijian is defined as potential gap between different layers in the three-dimensional network structure formed by the twelve meridian tendons. Various pathological changes of the meridian tendons lead to the adhesion and closure of fenrou zhijian, causing abnormal mechanical conduction of the meridian tendon system, which in turn leads to painful bi syndrome of meridian tendons. As such, restarting the fenrou zhijian is the key to acupuncture treatment for painful bi syndrome of meridian tendons. Under the guidance of musculoskeletal ultrasound, the level and the angle of needle insertion of acupuncture at fenrou zhijian could be accurately controlled, the efficacy of acupuncture is improved.十二经筋在体表形成的立体网络结构中不同层次间的潜在间隙称为“分肉之间”，经筋的各种病理变化导致“分肉之间”粘连而闭合，引起经筋系统力学传导异常，进而引发经筋痹痛，故重启“分肉之间”是针刺治疗经筋痹痛的关键。肌骨超声引导下针刺“分肉之间”可实现对层次和进针角度的精准掌握，提升针刺疗效。.
