| 目的：探讨中频电刺激股沟血管丛对下肢血液循环的影响。方法：32 名健康男性随机分为2 组，将LDF 探头、热敏探头以双
面胶固定在受试者右膝关节内侧上方5cm 处，电流强度为感觉阈上。一组接受调制中频电刺激，另一组是对照组。刺激时间为20
分钟，休息15 分钟后，连续监测时间为30 分钟，每5 分钟为一个时间段，生理信号记录的是第一个5 分钟、第三个5 分钟、第五
个5 分钟、第六个5 分钟共四次。记录指标为皮肤表面血流量、表面温度和心率变异性（HRV）。结果：研究表明，皮肤表面温度、血
流量、HRV 的LF 值随时间间隔出现明显变化，HF 与LF/HF 并没有显著变化；调制中频电组的部分指标与对照组有显著性差异。
结论：调制中频电组效果优于空白对照组，阈上强度的中频电刺激腹股沟血管丛能够明显改善下肢血液循环，防止下肢出现水肿
或麻木的情况。 |

| Objective: To explore the effect of low intensity of medium frequency electric stimulating on fold inguen vascular
plexus. Methods: 32 healthy men were randomly divided into two groups, which was defined the modulated medium frequency group
and the control group. Before the test, we put the LDF probe and the thermal probe fixed on the subject at 5cm above the right knee medial;
Put the modulated medium frequency electrodes on bilateral guinal vascular plexus. The control group also were placed modulated medium
frequency electrode, but with no current output; The ECG electrodes were to put on the body in the limb lead way. Current perception
was above the Sensory Thresholds, and the time of stimulation was 20 minutes. After the resting of 15 minutes, make the subjects
maintain relaxed lying position and continuous monitoring the result for 30 minutes, the result was extracted every 5 minutes. The indices
were skin blood flow, skin temperature and heart rate variability. Results: The results of the study indicate that, skin blood flow, skin temperature
and LF were significantly changed with time interval. However, HF and LF/HF had not changed significantly. The modulated
medium frequency group's indices greatly surpassed the control group's. Conclusion: The effect of MMFC group was better than the control
group and the stimulation of fold inguen vascular plexus by suprathreshold intensity of medium frequency electric can improve distal
lower limb skin blood flow obviously, which could prevent edema or anesthesia of lower limb. |
