Under the guidance of the "Sancai principle", based on the understanding of the etiology and pathogenesis of the imbalance of muscles and bones in bi syndrome of neck region, holistic treatment should be used. The needle-knife release therapy is applied at corresponding acupoints in the three parts i.e. head, neck and back including Tiancai points (Naohu [GV 17] and Naokong [GB 19]), Rencai points (neck Jiaji [EX-B 2]), and Dicai points (Dazhui [GV 14], Quyuan [SI 13] and Tianzong [SI 11]). According to the layers of the lesion's meridians and muscles, the needle-knife is inserted into skin, muscle and bone to relax the tendons and treat bone disorders, and restore the normal mechanical balance of neck.
在三才思想指导下，基于对项痹病筋骨失衡病因病机的认识，整体施治，选择头颈背3个部位的相应穴位（天才穴：脑户、脑空；人才穴：颈夹脊；地才穴：大椎、曲垣、天宗），应用针刀松解治疗，根据病变经筋所在层次分别针至皮、肉、骨，调筋治骨，恢复颈部正常力学平衡。.
