Electric signals from a chest skin electrode can be conducted to the heart and activate contraction. In the present study, normal and diabetic rabbits were stimulated by skin electrode on the abnormal bladder projection area using three levels of exporting voltage (5.84 V, 8.00 V, and 11.00 V). Results demonstrated significantly attenuated electric signals from both groups, in particular the diabetes group. The skin electrode signals were conducted to the bladders, and all vesical signals increased according to strength of stimulating signals from the skin electrode. However, vesical signals from diabetic rabbits were less than those from normal rabbits at the same stimulating strength of exporting voltage. Vesical pressures from the two groups increased along with increased vesical signals, but vesical pressure was less those from diabetic rabbits than in normal rabbits (basic status and different stimulating levels). Linear correlation analysis showed a significantly positive correlation between vesical pressure and signal. These results demonstrated that electric signals from skin electrodes resulted in increased vesical pressure, and vesical pressure increased along with stimulation strength.
皮肤电极的电信号可以传入心脏并引发收缩。在本研究中，正常和糖尿病兔子的异常膀胱投影区域接受皮肤电极刺激，导出电压分别为 5.84V、8.00V 和 11.00V。结果表明两组的电信号都明显减弱，尤其是糖尿病组。皮肤电极信号传入膀胱，随着皮肤电极刺激信号的增强，所有膀胱信号都增加。然而，在相同的导出电压刺激强度下，糖尿病兔子的膀胱信号小于正常兔子。两组的膀胱压力随着膀胱信号的增加而增加，但糖尿病兔子的膀胱压力小于正常兔子（基础状态和不同刺激水平）。线性相关分析显示膀胱压力与信号之间呈显著正相关。这些结果表明，皮肤电极的电信号导致膀胱压力增加，并且膀胱压力随着刺激强度的增加而增加。
