The participants in the EA group received EA treatment with a mixed current of 2 Hz/120 Hz at 12 acupuncture points (bilateral Zusanli [ST36], Xuanzhong [GB39], Yinlingquan [SP9], Sanyinjiao [SP6], Taichong [LR3], and Zulinqi [GB41]) twice per week for 8 weeks. Depending on the sites of pain, the additional acupuncture point Bafeng (EX-LE10) was available.
“To our knowledge, this is the first multicenter randomized controlled trial to evaluate the effectiveness and safety of EA treatment for the management in PDN. One limitation is that neither a placebo nor sham EA was used as an active control; therefore, the possibility of a placebo effect was not excluded. In conclusion, the results of this study
demonstrate that EA treatment is effective for reducing pain and improving sleep disturbance and quality of life in PDN. In addition, EA treatment was well tolerated and safe during this study. These findings suggest that EA treatment may be recommended as a nonpharmacological treatment for pain reduction in PDN.”
