【摘要】：背景:飞行人员由于长时间保持固定坐姿,腿部活动范围受限,易引起腿部血液循环不畅,产生疲劳感。研究显示中频电流具有明显的促进局部血液循环的作用。目的:探讨低强度中频电刺激腰交感神经节对健康男性下肢远端皮肤血液循环的影响,并与静态干扰电疗法作比较。方法:在39名健康男性腰部交感神经节(T10～L2)放置中频电电极,右内踝关节上方2cm处放置激光多普勒血流监测仪探头,电流强度为感觉阈。分别给予调制中频电刺激、静态干扰电刺激及不通电刺激。激光多普勒血流监测仪记录静息15min后及电刺激20min末的血流值。结果与结论:与基线值比较,经调制中频电刺激的受试者下肢远端皮肤血流灌注量有所增加,而未给予电刺激及静态干扰电刺激的受试者下肢远端皮肤血流灌注量有所减少,尤其是经静态干扰电刺激后,明显低于基线值(P0.05)。说明调制中频电刺激可以改善下肢的血液循环,对长时间保持固定坐姿产生的疲劳有缓解功能。
[Abstract]:Background: for a long time, the flight personnel maintain a fixed posture, limited range of leg activities, easy to lead to poor blood circulation in the legs, resulting in fatigue. Studies have shown that if current has a significant role in promoting local blood circulation. Objective: to investigate the effect of low intensity middle frequency stimulation on blood circulation of distal skin of lower extremity in healthy male and compare it with static interference electrotherapy. Methods: an intermediate frequency electrode was placed in the lumbar sympathetic ganglion of 39 healthy men and a laser Doppler blood flow monitor probe was placed at the 2cm above the right medial ankle. The current intensity was the sensory threshold. Modulation medium frequency electrical stimulation, static interference electric stimulation and non-electric stimulation were given respectively. Laser Doppler blood flow monitor was used to record the blood flow after resting 15min and electrical stimulation of 20min. Results and conclusion: compared with the baseline value, the blood perfusion of the distal lower extremity skin was increased in the subjects treated with modulation medium frequency electrical stimulation, but decreased in the subjects without electrical stimulation and static interference electrical stimulation. Especially after static interference electric stimulation, it was obviously lower than the baseline value (P 0.05). The results show that modulating middle frequency electrical stimulation can improve the blood circulation of lower extremity and alleviate the fatigue caused by maintaining a fixed sitting position for a long time.
