The blood velocities in peripheral arteries were measured by pulsed Doppler ultrasound before, during and after electrotherapy treatment. 43 experiments with "Diadynamic", "High Voltage" and "Interference" treatment were performed on 22 healthy subjects aged 21-65 years. This treatment did not lead to an increase in mean blood velocities in the arteries supplying the area concerned. The intensities of stimulation were below the threshold for inducing muscle contractions. As discomfort due to the sensation of the electrical stimulation arose, a transitory decrease in velocities occurred. Simultaneous measurements from corresponding arteries on the treated and untreated sides showed no difference in blood velocity variation pattern. It is thus likely that the transient vasoconstrictor effect related to treatment is mediated by the sympathetic nervous system.
在电疗治疗前、治疗期间和治疗后，通过脉冲多普勒超声测量外周动脉中的血流速度。对22名年龄在21至65岁之间的健康受试者进行了43次“动态直流电疗法”“高压电疗法”和“干扰电疗法”治疗实验。这种治疗并未导致供应相关区域的动脉平均血流速度增加。刺激强度低于诱发肌肉收缩的阈值。由于出现了电刺激引起的不适，血流速度出现了短暂下降。在治疗侧和未治疗侧的相应动脉同时进行测量，结果显示血流速度变化模式没有差异。因此，与治疗相关的短暂血管收缩效应很可能是由交感神经系统介导的。
