针刺合谷穴对合谷及迎香穴区温度变化的影响

Effect of Point Hegu(LI 4) Acupuncture on Points Hegu(LI 4) and Yingxiang(LI 20) Region Temperature

目的研究不同刺激量针刺合谷穴对合谷穴区及对侧迎香穴区红外热像温度的影响。方法将30名缺血性脑卒中致中枢性面瘫患者依据不同刺激量随机分为合谷1-4组和对照组。观察针刺过程中合谷穴区、对侧迎香穴区红外温度变化。结果针刺合谷穴前后,合谷穴及对侧迎香穴区红外温度发生先降低再升高的变化(P<0.05)。结论针刺合谷穴后合谷穴局部与对侧面部迎香穴区体表红外热像温度变化具有相关性,提示经脉体表循行路线具有特异性,不同合谷组的两穴区温度变化虽有不同,但尚未发现明确规律。

Objective To investigate the effects of point Hegu （LI 4） acupuncture with different stimulation intensities on infrared thermographic temperature at point Hegu （LI 4） region and contralateral point Yingxiang （LI 20） region. Methods Thirty patients with ischemic stroke-induced central facial paralysis were randomly allocated to Hegu 1-4 groups and a control group. Changes in infrared temperature at point Hegu （LI 4） region and contralateral point Yingxiang （LI 20） region were observed during acupuncture. Results After point Hegu （LI 4） acupuncture, infrared temperature at point Hegu （LI 4） region and contralateral point Yingxiang （LI 20） region changed from an early drop to a subsequent rise （P〈0.05）. Conclusion Changes in body surface infrared thermographic temperature at point Hegu （LI 4） region and contralateral facial point Yingxiang （LI 20） region after point Hegu （LI 4） acupuncture are correlative, suggesting that the meridian running route on the body surface has specificity. Although temperature changes at the two point regions in different Hegu groups are different, definite regularities are not found.
