Real-time cerebral functional MRI showed that compared with non-sensation after sham needling, true needling activated Brodmann areas 3, 6, 8, 9, 10, 11, 13, 20, 21, 37, 39, 40, 43, and 47, the head of the caudate nucleus, the parahippocampal gyrus, thalamus and red nucleus. True needling also deactivated Brodmann areas 1,2, 3, 4, 5, 6, 7, 9. 10. 18.24.31.40 and 46.展开更多

Randomized control trials that compared manual acupuncture with deqi, manual acupuncture without deqi, and conventional treatment of western medicine were included. Languages were limited to English and Chinese. Two authors independently selected eligible studies, assessed methodological quality and the effects of deqi, and extracted outcome data. The mean difference(MD) and standardized mean differences(SMDs) with 95% confidence intervals(CIs) were calculated by Stata 15.0 to conduct an NMA based on a frequentist framework.Results: Fourteen trials with a total of 1868 subjects were included. The direct and indirect comparisons were authentic, according to inconsistency tests. The Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC) pooled results indicated that there was no significant effect of deqi(SMD=-0.23, 95% CI [-0.81, 0.35]). The pooled results of visual analogue scale(VAS) were similar to those of WOMAC(MD=-0.53, 95% CI [-1.03, 0.02]).Conclusion: As a summary of the currently available research, the NMA results indicated that deqi effect might not be the crucial factor for the effectiveness of manual acupuncture.展开更多

In this report, the relationship between ＂deqi＂ and these factors was explored in terms of different acupuncture methods and quantity and depth of stimulus. Methods Ancient literature about ＂deqi＂, as well as related literature for clinical and basic research on ＂deqi＂ in recent 10 years were systematically collected. Results （1） Cerebral functional imaging technology and the scale of ＂deqi＂ were the most common quantitative indexes for ＂deqi＂ in recent 10 years. （2） There were many factors influencing ＂deqi＂ in acupuncture, which involved personal physiological status, nature of disease, anatomical features under the acupoint, different acupuncture methods, quantity and depth of stimulus, etc. Different acupuncture methods, quantity and depth of stimulus would bring different influences on and mechanisms of ＂deqi＂. Conclusion （1） ＂Deqi＂ is not equal to needling sensation; （2） recessive needling sensation should be re-recognized; （3） the sensation of doctor should be paid attention; （4） The meaning of ＂deqi＂ should be re-defined and re-understood.展开更多
