表皮在电极-皮肤界面的导电特性中起主要作用,但是当直流电通过机体时,也还会受到其它组织的阻力。治疗中因湿衬垫和电流本身的刺激作用,治疗部位的极间电阻会下降,而致电流强度自行上升。为更好地指导临床操作,我们进行了直流电作用后极间电阻变化的实验观察,现总结如下。 The epidermis plays a major role in the electrical conductivity of the electrode-skin interface, but also resistance from other tissues when the DC is passed through the body. Treatment due to wet liner and the current itself stimulus, the treatment site will be reduced resistance between the electrodes, and the resulting increase in the intensity of the current. In order to better guide the clinical operation, we conducted a direct current experiment after the change in resistance between the electrodes, are summarized as follows.
