Methods Sixty inpatients with peripheral facial neuritis were randomly divided into two groups： observation group （Taiji needling group, n=30） and control group （conventional acupuncture group, n=30）; the treatment was conducted once a day, which was not stopped until the patients were discharged from hospital after recovery. The curative effect was evaluated before and after treatment by applying the therapeutic outcome rating scale of peripheral facial neuritis （portmann scale）. Results The improve merit of efficacy indices in the observation group was superior to that in the control group, and the difference was statistically significant （P〈0.05）; the course of treatment was shortened in the observation group compared with the control group, and the difference was also statistically significant （P〈0.05）. Conclusion The efficacy index of Taiji needling in treatment of peripheral facial neuritis is superior to that of conventional acupuncture, and Taiji needling can obviously shorten the course of treatment.展开更多

The author began using Taiji, Chen style Chan Si Gong (Reeling Silk), and Zhan Zhuang (standing meditation) to relieve chronic pain since 1986. After more than two years of Qigong training, the structure of the author's foot changed from the previous deformity to normal foot shape. These changes enabled the author to walk normally and to be free from persistent chronic pain. The article discussed the methods of using Qi currents and other issues that need to be paid attention to when practicing Tai chi, such as how to adjust one's mental focus and maintain a state of relaxation to "mindful". Tai chi involves a number of internal "micro-adjusting" about how these techniques relax and strengthen muscles to reduce chronic pain. The report and discussion on the treatment principle of Qigong can provide new strategies for the treatment of chronic pain.展开更多
