不同留针时间对针刺治疗肩周炎临床疗效的影响

Effect of different needling retaining times in clinical curative effect of acupuncture on the treatment of periarthritis humeroscapularis

目的：观察不同留针时间对针刺治疗肩周炎临床疗效的影响。方法将符合入选标准的60例肩周炎患者采用随机数字表分为2组，每组30例。均于患侧肩部常规取穴，针刺后分别静留针20 min和40 min。2组均治疗20次。采用视觉模拟量表（Visual Analogus Scale, VAS）及Constant-Murley评分法（Constant-Murley Score, CMS）评价留针20 min与留针40 min的疗效。结果治疗后，留针40 min组VAS评分[（2.67±1.03）分比（3.60±1.48）分，t＝-3.251]低于留针20 min组（P＜0.01）、CMS评分[（73.20±10.88）分比（66.47±12.62）分，t＝-2.199]高于留针20 min组（P＜0.05）。留针20 min组、留针40 min组治愈率分别为3.3%（1/30）、26.7%（8/30），差异有统计学意义（χ2＝4.706，P＝0.030），总有效率分别为90.0%（27/30）、96.7%（29/30），差异无统计学意义（χ2＝0.268，P＝0.605）。结论针刺治疗肩周炎留针40 min在改善临床症状、恢复功能等方面均优于留针20 min，但总有效率无明显差异。

Objective To observe the effect of different needling retaining times in clinical curative effect of acupuncture on the treatment of periarthritis humeroscapularis.Methods A total of 60 patients, who met the inclusion criteara, were randomly divided into 2 groups according to random number table method, 30 patients in each group. Both groups were treated with the same acupuncture therapy for 20 times, but the needling retaining times were different as 20 minutes and 40 minutes. The curative effect rates, Visual Analog Scale （VAS） and Constant-Murley Score （CMS） were evaluated.Results After the treatment, the VAS scoresin 40mins group was significantly lower than that in the 20 mins group （2.67 ± 1.03vs.3.60 ± 1.48,t=-3.251, P〈0.01）; the CMSin 40 mins group was significantly higher than the 20 mins group （73.20 ± 10.88vs.66.47 ± 12.62,t=-2.199,P〈0.05）. The curative effect rates of the 40 mins group was 26.7% （8/30）, which was significantly higher than 3.3% （1/30） in the 20 mins group （χ2=4.706,P=0.030）. The total effective rates in the 40 mins group was 90.0% （27/30）, which was significantly higher than 96.7% （29/30） in the 20 mins group （χ2=0.268,P=0.605）.Conclusions Acupuncture treatment for the patients with periarthritis humeroscapularis showed that the 40 minutes of needling retaining times had better symptom improvement and restore function effects than 20 minutes, however the total effective rate was no significant difference.
