Fibromyalgia patients who exhibit greater sensitivity to pain are more likely to respond to sham acupuncture, and more likely to experience a worsening of pain after verum acupuncture, report US researchers. A cohort of 114 fibromyalgia patients received baseline pressure pain testing and were then randomised to either verum or sham acupuncture. Verum acupuncture consisted of needling nine acupuncture points (Baihui DU-20, right ear Shenmen, left Quchi L.I.-11, right Hegu L.I.-4, left Yanglingquan GB-34, left Zusanli ST-36, left Sanyinjiao SP-6 and right Taichong LIV-3), while sham treatment involved needling at non-acupuncture points. Participants received one to three treatments a week week for a total of 18 treatments. Participants who had higher pressure pain thresholds at baseline demonstrated a greater reduction in clinical pain following verum acupuncture, while participants who had lower baseline pain pressure thresholds showed a better analgesic response to sham acupuncture. In addition, patients with lower pressure pain thresholds reported exacerbated pain following verum acupuncture.
