中风偏瘫患者穴位内电阻的比较研究

Comparative Study of Acupoint Internal Resistance of Apoplexy Hemiplegia Patients

目的:中风偏瘫患者由于健、患侧的功能差异,可能是研究穴位特异性比较好的研究对象,试验希望通过不同的探针方法检测穴位电阻的变化,以探索穴位的特异性。方法:以普通针灸针和绝缘针灸针作为探针,应用Agilent 34401A 6 1/2 Digit Multimeter数字示波器观察中风偏瘫患者针刺留针过程中穴位内电阻变化。结果:1应用普通针进行的检测中,无论穴位或穴位旁,留针前后阻值有显著性改变(P<0.01),而且留针后的电阻是显著增大的;应用普通针测得的穴位和穴位旁电阻差异无统计学意义(P>0.05)。2应用绝缘针检测的穴位或穴位旁电阻,留针前后阻值有显著性改变(P<0.01),而且留针后的电阻是显著减小;留针前、后的穴位和穴位旁电阻差异无统计学意义(P>0.05)。3应用普通针和绝缘针两种探测方法检测的穴位(及穴位旁)内部电阻有显著不同,且R绝缘针>R普通针;而且两种方法引起的穴位内电阻变化趋势和快慢程度都相关极大。结论:穴位电特性变化多端,研究结果受影响极多,不能轻易下结论,不断的深入探索和研究是非常必要之途。

Objective： To research the change of apoplexy hemiplegia patients＇ acupoint internal resistance by different detective methods or during retaining needling. Methods： Applying general acupuncture needling and insulated acupuncture needling as probe,Agilent 34401A6 1 /2 Digit Multimeter as the recording instrument detected acupoint interanl resistance and we compared the difference of resistance between acu- point and non- acupoint. Result： 1In the general needle test：resistance after retaining needling hoisted significantly compared with before retaining needling（ in acupoint or non- acupoint）（ P〈0. 01） and it did not change significantly in acupoint compared non- acupoint. 2 In the insulated needle test： resistance after retaining needling declined significantly compared with before retaining needling（ in acupoint or non- acupoint）（ P〈0. 01）. The other result was the same to the general needling test. 3The resistance was higher significantly insulated needling compared to that in general needling test. Conclusion： The value of acupoint internal resistance is related to detective method and mode.
