基于红外热成像观察针刺气郁体质者太冲穴温度变化及循经传导现象OA

Objective:To observe changes in local acupoint temperature after needling Taichong(LR3)and the meridional conduction phenomena in individuals with Qi-stagnation constitution.Methods:60 participants with Qi-stagnation constitution were randomly assigned to the study group and the control group,with 30 participants in each group.The study group was treated with needling LR3,whereas the control group underwent sham acupuncture.Changes in temperature at LR3 and at acupoints along the corresponding meridian pathway,as well as meridional conduction phenomena,were observed in both groups before and after the intervention.Results:Within-group comparisons showed that the local temperatures of all observed acupoints decreased after acupuncture in the study group,with statistically significant differences compared with baseline(P<0.05).In the control group,no statistically significant differences were observed in the local temperatures of acupoints before and after sham needling(P>0.05).Between-group comparisons demonstrated that the reduction in local acupoint temperature in the study group was significantly greater than that in the control group after the intervention(P<0.05).Additionally,the frequency of temperature decreases at each acupoint in the study group was higher than that in the control group,with statistically significant differences(P<0.05).Conclusion:Using infrared thermography,needling Taichong(LR3)in individuals with Qi-stagnation constitution was shown to reduce the local temperature at LR3 and at nearby acupoints along the Liver meridian,suggesting a potential regulatory effect on Qi-stagnation constitution.Meridional conduction was observed after needling LR3,which may partially support the objective existence of meridians.
