Abstract
Objective
To observe the clinical efficacy of electroacupuncture (EA) with different frequencies in treating migraine.
Methods
Ninety patients with migraine were divided into a low frequency electroacupuncture (LF-EA) group, a high frequency electroacupuncture (HF-EA) group and a variable frequency electroacupuncture (VF-EA) group by the random number table method. Shuaigu (GB 8), Hegu (LI 4), Waiguan (TE 5), Taichong (LR 3), Taiyang (EX-HN 5), Fengchi (GB 20) and Ashi points were selected for all three groups. After achieving needling sensation (Deqi), the LF-EA group received 2 Hz continuous wave EA stimulation; the HF-EA group received 100 Hz continuous wave EA stimulation, and the VF-EA group received 2 Hz/100 Hz sparse-dense wave EA stimulation. The EA stimulation lasted for 30 min in all the three groups, once a day, 10 times as a course, and the clinical efficacy was evaluated after 2 consecutive courses of treatment.
Results
After treatment, the total effective rates in the LF-EA group, HF-EA group and VF-EA group were 77.7%, 83.3% and 93.3%, respectively. The difference in total effective rate between the LF-EA and HF-EA groups was not statistically significant (P>0.05), but the total effective rate was significantly higher in the VF-EA group than in the LF-EA and HF-EA groups (both P<0.01). After treatment, the headache scores significantly decreased in all three groups (all P<0.01). The difference in headache score between the LF-EA and HF-EA groups was not statistically significant (P>0.05), while the score was significantly lower in the VF-EA group than in the LF-EA and HF-EA groups (both P<0.01).
Conclusion
VF-EA (2 Hz/100 Hz), compared with LF-EA (2 Hz) and HF-EA (100 Hz), shows superior clinical efficacy in treating migraine.
摘要
目的
观察不同频率电针治疗偏头痛的临床疗效。
方法
将90例偏头痛患者按随机数字表法分成低频电针组,高频电针组和变频电针组。三组均取率谷、合谷、外关、太冲、太阳、风池和阿是穴, 针刺得气后, 低频电针组接受2 Hz连续波电针刺激, 高频电针组接受100 Hz连续波电针刺激, 变频电针组接受2 Hz/100 Hz疏密波电针刺激。三组刺激时间均为30 min。每日治疗1次, 10 次为1个疗程, 连续治疗2个疗程后评定疗效。
结果
治疗后, 低频电针组、高频电针组和变频电针组的总有效率分别为77.7%、83.3%和93.3%。低频电针组与高频电针组总有效率无统计学差异(P<0.05), 变频电针组总有效率高于低频电针组和高频电针组, 组间差异均具有统计学意义(均P>0.01)。治疗后, 3组头痛评分均较本组治疗前明显下降(均P<0.01); 低频电针组与高频电针组头痛评分无统计学差异(P>0.05), 变频电针组头痛评分下降程度显著低于低频电针组和高频电针组, 组间差异均具有统计学意义(均P<0.01)。
结论
变频电针(2 Hz/100 Hz)治疗偏头痛的疗效优于低频(2 Hz)和高频(100 Hz)。
