PMID 23713304

Abstract

To observe the clinical efficacy of acupuncture at Jiaji (EX-B 2) points mainly for lumbar myofascial pain syndrome (MPS). Sixty-six cases of MPS were randomized into an acupuncture group and a lidocaine group, 33 cases in each group. The acupuncture group was treated with acupuncture at Jiaji (EX-B 2) points combined with needling local myofascial trigger points (MTrP), and the lidocaine group was treated with local block at trigger points with lidocaine injection. The treatment was given once every 2 days. After three and five times of the treatment, the simplified McGill scale, Oswestry disability index (ODI) and pressure-pain threshold were assessed to compare the therapeutic effects between the two groups. After treatment, the scores of simplified McGill and ODI of two groups were obviously reduced while the score of pressure-pain threshold was obviously increased (all P < 0.01). After three and five times of the treatment, there were no significant differences in above scores between the two groups (all P > 0.05). Acupuncture at Jiaji (EX-B 2) points combined with needling MTrP is an effective and safe therapy for lumbar MPS, the therapeutic effect is equal to lidocaine block.
