不同留针时间对针刺治疗缺血性中风疗效的影响

目的:观察不同留针时间对针刺治疗缺血性中风疗效的影响。方法:将251例缺血性中风患者按病情程度分层随机分为3组,针刺留针时间分别为20、40和60分钟。主要观察神经功能缺损程度评分及临床疗效。结果:3组治疗后神经功能缺损程度评分变化比较,经Wilcoxon配对符号秩和检验,除水平凝视变化外,其余指标治疗前后变化差异均有非常显著性意义(P<0.01);3组治疗前后神经功能缺损程度评分差值平均秩比较,上肢肌力、手肌力和总分3个指标组间差异有显著性或非常显著性意义(P<0.05,P<0.01);3组上肢肌力、手肌力、总分等3个指标变化,用Mann-Whitney两样本秩和检验进行组间两两比较,结果20分钟组与60分钟组比较,差异有显著性意义(P<0.05),40分钟组与60分钟组之间上肢肌力比较,差异有显著性意义(P<0.05);3组疗效比较,经Kruskal-Wallis秩和检验,差异有非常显著性意义(P<0.01),经Mann-Whitney秩和检验,组间两两比较,40分钟组与60分钟组差异有显著性意义(P=0.013),20分钟组与60分钟组比较,差异有非常显著性意义(P=0.000)。结论:留针时间与针刺治疗缺血性中风的疗效存在一定时效联系。

A Clinical Observation on the Treatment of Ischemic Apoplexy by Different Needling- retention Times

Objective: To observe the curative effect of needling - retention times (NT) for ischemic apoplexy (IA) . Methods: 251 cases of IA were allocated to 3 groups randomly, the NT being 20, 40 and 60 min individually. The scoring of nervous dysfunction severity and clinical curative effect were observed. Results: The scorings of nervous dysfunction severity in 3 groups were compared. Under Wilcoxon' s rank sum test, all parameters except horizontal gaze before and after treatment changed significantly (P < 0.01) .In the scoring of 3 groups before and after treatment, the myodynamia of upper limbs, myodynamia of hands and total scoring showed significant or very significant difference ( P < 0. 05, P < 0. 01). The comparison by Mann - Whitney rank sum test showed that 20 min group and 60 min group showed significant difference ( P < 0. 05). By Kruskal - Wallis rank sum test, the effects of 3 groups were very significantly different (x2 = 18. 159, P = 0. 000). By Mann - Whitney rank sum test, the 40 min group and 60 min group showed significant difference (P = 0.013), and the 20 min group and 60 min group showed very significant difference (P = 0.000) .Conclusion: Acupuncture with needling - retention for 60 min exerts better effect for IA.
