title: [Evaluation of the immediate effect of acupuncture on cervical spondylosis of vertebral artery type based on orthogonal design].
abstract: OBJECTIVE
  To analyze the differences in the immediate effect of acupuncture on cervical spondylosis of vertebral artery type among three factors: needling technique, acupoint selection and time of needle retaining so as to option the best therapeutic program.
  
  
  METHODS
  Thirty-two cases were observed and randomly divided into 8 groups, 4 cases in each one. The orthogonal design of three factors and two levels was adopted. There were needling technique (electroacupuncture, reinforcing and reducing method), acupoint selection [C4-C7 Jiaji (EX-B 2) and three needles of neck: Tianzhu (BL 10), Jingbailao (EX-LHN 15), Dazhu (BL 11)] and time of needle retaining (5 min, 15 min). L8 (2(7)) orthogonal design table was arranged in the trial. The changes in mean velocity (Vm) of vertebral artery (VA) and basilar artery (BA) were observed before and after acupuncture.
  
  
  RESULTS
  The immediate effect of VA-BA blood flow was the most significant after electroacupuncture at C4-C7 Jiaji (EX-B 2), with continuous wave for 5 min. This method and acupoint selection greatly influenced the therapeutic results (both P<0.05).
  
  
  CONCLUSIONS
  The optimized therapeutic program of the immediate effect of acupuncture for cervical spondylosis of vertebral artery type is electroacupuncture + C4-C7 Jiaji (EX-B 2) + 5 min. The importance of different factors for the immediate effect in acupuncture treatment of cervical spondylosis of vertebral artery type is: acupoint selection > needling technique > time of needle retaining.
