This study was performed to observe the influence of sham and different verum acupuncture manipulations on skin temperature of the stimulated acupoint in healthy volunteers. Thirty-seven healthy volunteers with a mean age of 25.4 ± 2.2 years were enrolled in the study. All volunteers had experienced acupuncture before. They received sham acupuncture and two different kinds of verum acupuncture stimulation (lifting-thrusting and twisting-rotating) on Zusanli (ST36). The skin temperature of ST36 was measured before acupuncture, after needle insertion, after needle manipulation, immediately after removal of the needle, and as further control 5 minutes after removal of the needle using a FLIR i7 infrared thermal camera. During the measurement, the needling sensations of volunteers were enquired and recorded. During the sham acupuncture stimulation, the skin temperature of ST36 decreased in the first 5 minutes, when the point was exposed, and then increased gradually. During verum acupuncture stimulations, the skin temperature increased continually and then decreased in the last phase. The increase in temperature caused by lifting-thrusting stimulation was significantly higher than that of twisting-rotating manipulation, which may be related to the stimulation intensity.
本研究旨在观察假针刺和不同的针刺手法对健康志愿者刺激穴位皮肤温度的影响。37 名平均年龄为 25.4 ± 2.2 岁的健康志愿者参与了这项研究。所有志愿者之前都有过针刺治疗的经历。他们接受了假针刺和两种不同的针刺刺激（提插和捻转），刺激足三里（ST36）。使用 FLIR i7 红外热像仪在针刺前、针刺后、针刺操作后、针拔出即刻以及针拔出后 5 分钟测量 ST36 的皮肤温度。在测量过程中，询问并记录志愿者的针感。在假针刺刺激期间，当穴位暴露时，ST36 的皮肤温度在前 5 分钟内下降，然后逐渐升高。在真针刺刺激期间，皮肤温度持续升高，然后在最后阶段下降。提插刺激引起的温度升高明显高于捻转刺激，这可能与刺激强度有关。
