[Acupuncture combined with cranial electrotherapy stimulation on generalized anxiety disorder: a randomized controlled trial].

OBJECTIVE: To observe the therapeutic effect of acupuncture combined with cranial electrotherapy stimulation (CES) on generalized anxiety disorder (GAD). METHODS: A total of 200 patients with GAD were randomized into an acupuncture+CES group, an acupuncture group, a CES group and a medication group, 50 cases in each one. In the medication group, patients were treated with tandospirone citrate tablet orally, 10 mg after breakfast, lunch and dinner respectively. In the CES group, CES was adopted by SCS brain electromedical instrument, 60 min each time, once a day. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Sishencong (EX-HN 1), Yintang (GV 29), Shenting (GV 24), etc., 30 min each time, once a day. In the acupuncture+CES group, CES was adopted before acupuncture. Treatment of sixty days was required in the 4 groups. Before and after treatment, the scores of Hamilton anxiety scale (HAMA), World Health Organization's quality of life questionnaire-brief version (WHOQOL-BREF) and treatment emergent symptom scale (TESS) were observed, the clinical effect was evaluated, and the relapse of anxiety during follow-up of 1 year after treatment was recorded in the 4 groups. RESULTS: Compared before treatment, the scores of HAMA after treatment were decreased (P<0.05), the scores of WHOQOL- BREF after treatment were increased in the 4 groups (P<0.05), and the improvements of above scores in the acupuncture+CES group were greater than the other 3 groups (P<0.05). The score of TESS after treatment and the relapse rate of 1-year follow-up in the medication group were higher than those in the other 3 groups (P<0.05). The total effective rate in the acupuncture+CES group were superior to the other 3 groups (P<0.05). CONCLUSION: Acupuncture combined with CES can effectively relieve the symptoms in patients with GAD, improve the quality of life, reduce the occurrence of adverse reactions and the relapse rate, and its clinical effect is obviously superior to the western medication, the simple application of acupuncture or CES.
