Observations on the Short-term and Long Term Effects of Point Houxi（SI 3） Electroacupuncture on Acute Lumbar Sprain

目的：观察电针后溪穴治疗急性腰扭伤的临床疗效。方法：采用随机数字表将300例急性腰扭伤患者随机分组，其中电针组选用后溪穴，药物组用莫比可治疗，结果：近期疗效比较，电针组有效率为97．3％，药物组有效率为89．3％，电针组近期疗效评分的平均秩和较药物组低（P〈0．01），有显著性差异；远期疗效比较，电针组有效率为99．3‰药物组有效率为93．2％，电针组远期疗效评分的平均秩和较药物组低（P〈0．01），二者之间有显著性差异。结论：电针后溪穴与口服莫比可治疗急性腰扭伤，均有显著疗效，但电针组的近期疗效和远期疗效均优于药物组。

Observations on the short-term and long term effects of point Houxi(SI 3) electroacupuncture on acute lumbar sprain

Objective: To investigate the clinical efficacy of point Houxi(SI 3) electroacupuncture for treating acute lumbar sprain. Methods: Three hundred patients with acute lumbar sprain were randomly grouped with a random number table. The electroacupuncture group was treated by electro-acupuncture at point Houxi (SI 3) and the medication group, with meloxicam. Results: A comparison of the short-term effects showed that the efficacy rate was 97.3% in the electroacupuncture group and 89.3% in the medication group. The average rank of the short-term effect score was lower in the electroacupuncture group than in the medication group (P<0.01); there was a significant difference between the two groups. A comparison of the long-term effect showed that the efficacy rate was 99.3% in the electroacupuncture group and 93.2% in the medication group. The average rank of the long-term effect score was lower in the electroacupuncture group than in the medication group (P<0.01); there was a significant difference between the two groups. Conclusion: Both point Houxi (SI 3) electroacupuncture and meloxicam have a marked effect on acute lumbar sprain, but the short-term and long-term effects are better in the electroacupuncture group than in the medication group.
