中风病及其虚实证候的耳穴电阻抗非线性特征

目的：探讨中风病及其虚实证候的耳穴电阻抗非线性特征，为中风病证候的客观化研究提供依据。 方法：采集中风病例与健康人群相关耳穴电学特征数据，采用量化积分表方法量化中风病证候，判断证候虚实，并通过研究耳穴非线性面积、弛豫面积和平衡系数在中风病例与健康人群中的异同，以及中风虚实证候间的差异，分析中风病及中风病虚实证候与耳穴电学特征的相关性。 结果：中风病人相关耳穴的电学特征参数不同于健康人群，差异有统计学意义（P＜0.05，P＜0.01），耳穴肝、脾具有非常显著的辅助诊断意义，其次是内分泌、脑干，再次是肾、肾上腺，最后是交感、皮质下和心；中风病虚实证候相关耳穴的电学特征参数比较，差异亦有统计学意义（P＜0.05，P＜0.01），耳穴交感、肾可较明确地诊断中风病虚实证候，其次是内分泌，再次是神门和肾上腺。 结论：在所观察的耳穴中，初步筛选出了对中风病诊断和中风病虚实证候诊断有价值的特异性耳穴，为中风病及其虚实证候诊断客观化研究提供了参考依据。

Impedance characteristics of ear acupoints in identifying excess or deficiency syndrome of stroke

Objective:To explore the impedance characteristics of ear acupoints in stroke patients with excess or deficiency syndrome,and to provide basis data for objective study of the syndromes of stroke.Methods:The data of electrical characteristics of ear acupoints in stroke patients and healthy people were collected,and excess syndrome and deficiency syndrome of stroke were identified by quantifying the syndromes of stroke using scales.The differences in impedance characteristics of ear acupoints between stroke p...
