【摘要】 目的:分析针刺电信号的特征和规律性,为探讨针刺手法的标准化提供试验依据。方法:以L1腰椎为中心暴露大鼠腰髓,分离出L4或L5脊髓背根神经并在近中端剪断,并将其外周端分离成数支细束,放置于铂金丝电极上。分别用提插补法、提插泻法、捻转补法、捻转泻法四种针刺手法针刺大鼠足三里穴,记录每种手法针刺时脊髓背根神经细束放电的情况,并采用非线性时间序列方法分析和小波分析方法分析针刺电信号的特征和规律性。结果:四种针刺手法针刺电信号的Lyapunov指数均大于零,而且其递归图都呈均匀分布;四种手法针刺电信号的小波能量熵平均值的大小不同。结论:针刺电信号具有平稳的混沌特性;不同针刺手法针刺电信号具有一定的定量特征。更多还原

【Abstract】 Objective To approach the characteristic and regularity of acupuncture electrical signals. Methods First of all,an operation is given in the center of L₁ upper or below,expose its spinal dorsal root,segregate nerve-tract of L4、5 and shear them on proximal part,then put them on platina silk electrode.After that,stimulate"Zusanli"point with four acupuncture manipulation,that is, lifting-inserting method;rotating method;first lifting- inserting then rotating;first rotating then lifting-inserting,record electro- information of each manipulation.At last,use bio-electro- technology methods the nonlinear time series acupuncture electrical signals.Results Lyapunov index number of acupuncture electrical analysis and wavelet entropy measure to analyze the regularity and specificity of the signals exceed zero in all,their recursion figure show uniform distribution and their average value of wavelet energy entropy are different.Conclusiou The acupuncture electrical signals have the characteristics of steady chaos and quantitative.更多还原
