基于肌电反应的合谷穴与面口部联系机制研究

摘要

Objective:To explore the specific relations between “Hegu”point and orofacial region mainly based on EMG.Methods:The healthy adults and the aged volunteers were acupunctured and the healthy infants were pressed on “Hegu”point to observe the effects of EMG in orofacial muscles.Results:For the healthy volunteers aged 20 ~30 acupunctured at “Hegu”point,the EMG response is most re-lated with the ipsilateral and contralateral orbicularisoris muscles.For the old healthy volunteers aged 65 ~75 acupunctured at “Hegu”point,the EMG response is most related with the both side of orbicularisoris muscles and masseter.For the healthy babies between 2 and 6 months old pressed on “Hegu”point,the occurrence rate of the EMG of the facial muscles was 100%.Conclusion:There is specific correlation of the body surface-surface between “Hegu”point and the orofacial region,which is closely related to age factor.%目的：运用肌肉电生理学方法，研究合谷穴区与面口部之间的特异性联系及其规律。方法：针刺健康成年及老年志愿者、按压健康婴儿志愿者合谷穴观察对面部肌肉的肌电活动的影响。结果：针刺20～30岁健康成年志愿者合谷穴，肌电反应与同侧及对侧口轮匝肌最相关；针刺65～75岁健康老年志愿者合谷穴，肌电反应与同侧及对侧口轮匝肌、咬肌最相关；按压2～6个月月龄的婴儿合谷穴，面部肌电出现率可达100％。结论：合谷穴与面口部之间存在“体表－体表”的相对特异性联系，此种联系与年龄因素密切相关。
