目的:观察不同频率的电针对大鼠游泳耐力影响,筛选出最佳频率参数.方法:选用Wistar大鼠,以大鼠负重游泳时间为指标,分为对照组、非穴组、电针低频,中频和高频组(2Hz组、15Hz组、100Hz组),取足三里、太冲穴,观察针刺前后游泳耐受时间的变化.结果:针刺后,15Hz和100Hz组游泳时间有增加,针刺前后有显著性差异(P＜0.05);且15 Hz组游泳时间升高的百分率与其他组相比有显著性差异(P＜0.05).结论:提示足三里、太冲穴给予频率为15 Hz的电针具有提高大鼠游泳耐力效应,15 Hz电刺激可能是所要筛选的最佳频率参数.

Objective: To observe the influence of electroacupuncture with different frequencies on rats swimming endurance and sift out the optimal frequency parameter.Methods: Wistar rats were randomly allocated to control group, non-acupoint group and electroacupuncture with low frequency group (EA with 2 Hz group), electroacupuncture with medium frequency group (EA with 15 Hz group), and electroacupuncture with high frequency group (EA with 100 Hz group), acupoints Zusanli (ST 36) and Taichong (LR 3) were punctured and rats load swimming time was used as an index, and the change of swimming endurance time before and after acupuncture was observed. Results: After electro-acupuncture, swimming time was increased in 15 Hz and 100 Hz groups respectively, with the significant differences between before and after acupuncture (P＜0.05). There was also a significant difference in the percentage of increase in swimming time between 15 Hz group and other groups (P＜0.05).Conclusion: It is suggested that electroacupuncture at acupoints Zusanli (ST 36) and Taichong (LR 3) with a frequency of 15 Hz could enhance rats's swimming endurance, and 15 Hz might be an optimal frequency parameter during the electrical stimulation.
