The clinical manifestation and clinical diagnosis and treatment of acupuncture for persistent somatoform pain disorder (PSPD) were observed to explore its etiology. It is found that the causative factor of PSPD is probably relevant with pain memory induced by the negative emotions during the first attack of pain, which is in the category of "depression" in TCM. In clinical diagnosis, the medical history should be explored to discover the potential etiology and determine the diagnosis. In treatment, the root cause should be considered, focusing on mind and qi regulation and associating with analgesia. It is different from the common treatment for analgesia in other pain disorders. For PSPD, the root cause is considerable, with "mind regulation" in priority. The acupoints relevant with mind on the head[such as Baihui (GV 20) and Sishencong (EX-HN1)], the acupoints for warming and tonifying the primary qi[such as Qihai (CV 6), Guanyuan (CV 4) and Zusanli (ST 36)] and the auricular points (such as xin (CO15), gan (CO12), shenmen (TF4), neifenmi (CO18)) are selected to regulate qi activity and calm down the mind. Additionally, the therapy for reliving pain specifically is applied with transcutaneous electric stimulation, 2 Hz/100 Hz, disperse-dense wave at bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) to erase pain memory trace. Ultimately, the therapeutic effects are achieved for mind regulation and pain easing.
