定量化针刺手法对穴位皮肤温度的影响

目的:验证提插补法针刺健康人右侧合谷穴对手阳明大肠经穴位皮肤温度的影响。方法:在30例健康人右侧合谷穴行提插补法,提插幅度5～8mm,频率100次/min,操作时间1min。采用PowerLab 8/30八通道高速记录仪及皮肤测温探头,以左侧合谷、右侧商阳、左侧商阳、左侧口禾髎针刺前30min、行针时1min、行针后30min的温度为观察指标。结果:提插补法针刺右侧合谷穴后,分别使左侧合谷由针刺前平均温度(27.89±3.56)℃上升到针刺后平均温度(28.30±2.81)℃,右侧商阳由针刺前平均温度(24.57±4.29)℃上升到针刺后平均温度(26.30±4.32)℃,左侧商阳由针刺前平均温度(25.13±5.07)℃上升到针刺后(26.58±4.92)℃,左侧口禾髎由针刺前平均温度(32.11±1.68)℃上升到针刺后(32.25±2.15)℃,以上穴位平均温度均有不同程度升高(P<0.01,P<0.05)。结论:提插补法对健康人穴位皮肤温度有升高的影响,且针刺后穴位皮肤温度的变化具有循经性及腧穴特异性。

Effect of quantitative acupuncture manipulation on the skin temperature of acupoints

Objective To verify the effect of lifting-thrusting reinforcing manipulation at Hegu(LI 4) of the right side on skin temperature on the Large Intestine Meridian.Methods Thirty healthy volunteers were needled at Hegu(LI 4) on the right side with lifting-thrusting reinforcing manipulation at the depth of 5-8 mm,100 times/min in freqency for 1 min.With PowerLab 8/30 eight-channel high-speed recorders and specially equipped skin temperature detector,the temperatures of Shangyang(LI 1) on the bilateral side,Hegu(LI 4) and Kouheliao(LI 19) on the left side were tested at the time 30 min before the needling,1 min during the needling and 30 min after the needling.Results After the lifting-thrusting reinforcing manipulation on the right Hegu(LI 4),the average skin temperature(27.89±3.56)℃ before the needling at the left Hegu(LI 4) was increased to(28.30±2.81)℃,the temperature of right Shangyang(LI 1)(24.57±4.29)℃ was increased to(26.30±4.32)℃,left Shangyang(LI 1)(25.13±5.07)℃ to(26.58±4.92)℃ and left Kouheliao(LI 19)(32.11±1.68)℃ to(32.25±2.15)℃,all of which were significantly improved to different degrees(P<0.01,P<0.05).Conclusion The lifting-thrusting reinforcing manipulation has an effect of increasing skin temperature of acupoints,and the temperature changes after needling are along meridians and have specificity of acupoins.
