温针灸对坐骨神经痛患者痛阈值的影响

Effect of warming needle moxibustion on pain threshold in the patient of sciatica

目的观察温针灸对坐骨神经痛患者痛阈值的影响,探索将痛阈值作为判断坐骨神经痛疗效的量化标准的可行性。方法将90例病人随机分为3组,每组30例。温针灸组取肾俞、大肠俞、环跳等穴,施以温针灸;西药组口服尼美舒利片;穴位注射组用654-2作穴位注射,取穴同温针灸组。结果3组治愈率分别为56·67%、26·67%、20·00%;3组总有效率分别为90·00%、73·33%、63·33%。温针灸组疗效优于西药组、穴位注射组(均P<0·01)。温针灸组痛阈值平均上升幅度优于西药组、穴位注射组(均P<0·01)。结论温针灸治疗坐骨神经痛能使痛阈值升高,改善临床症状,提高患者生活质量。

Objective To observe effect of warming needle moxibustion on pain threshold in the patient of sciatica. Methods Ninety cases were randomly divided into 3 groups, 30 cases in each group. The warming needle moxibustion group were treated with warming needle moxibustion at Shenshu （BL 23）, Dachangshu （BL 25）, Huantiao （GB 30）, etc; the western medicine group with oral administration of Nimeisulide; and the acupoint-injection group with injection of 654-2 into the same acupoints as those in the warming needle moxibustion group. Results The cured rates were 56.67%, 26.67% and 20.00% in the 3 groups, and the total effective rate were 90.00%, 73.33% and 63.33%, respectively, the therapeutic effect of the warming needle moxibustion group being better than those of other two groups （both P〈0.01）. The amplitude of pain threshold increase in the warming needle moxibustion group was higher than those of other two groups （both P〈0.01）. Conclusion Warming needle moxibustion can increase pain threshold, improve symptoms and raise quality of life for the patient of sciatica.
