Prolonged electrotherapeutic treatment increases the probability of skin irritation beneath the electrodes. One probable cause is acid and base formation under the electrodes. It has been assumed that high voltage pulsed galvanic stimulators do not produce these chemical reactions. The validity of this hypothesis was tested on 40 healthy subjects. Three groups of subjects received stimulation with different high voltage pulsed galvanic units, and one group of subjects served as a control group. Pretreatment and posttreatment measures of skin pH revealed no chemical reaction under the electrodes.
长时间的电疗会增加电极下方皮肤产生刺激的可能性。一个可能的原因是电极下方形成了酸和碱。据推测，高压脉冲电刺激器不会产生这些化学反应。在40名健康受试者身上对这一假设的有效性进行了测试。三组受试者接受了不同高压脉冲电刺激装置的刺激，一组受试者作为对照组。对皮肤pH值的预处理和后处理测量结果显示，电极下方没有化学反应。
