Clinical Effect and Infrared Thermogram on Electroacupuncture for Acute Lumbar Sprain

目的：观察电针治疗急性腰扭伤的，临床疗效以及治疗前后腰部红外热像图的变化。方法：采用随机数字表将295例急性腰扭伤患者随机分为电针组147例和药物组148例，电针组选用后溪穴治疗，药物组用美洛昔康片治疗，各组治疗前后进行腰部红外热像图的检查。结果：电针组和药物组痊愈率分别为71．4％和42．6％；有效率分别为93．9％和87．2％（P〈0．01）；电针组与药物组红外热像图治疗前后温度差分别为为2．52℃和0．80℃（P〈0．01），二者有显著性差异。结论：电针组和药物组治疗急性腰扭伤均有显著疗效，但电针组的总体疗效优于药物组，且电针组治疗前后红外热像图的升温效应也明显高于药物组。

Objective： To observe the clinical effect and infra-red thermogram changes for acute lumbar sprain. Methods： All 295 cases with acute lumbar sprain were randomly divided into an electroacupuncture group （147 cases） and medication group （148 cases）. The cases in electroacupuncture group were treated by needling Houxi （SI 3）, whereas those in the medication group were treated with Meloxicam tablet. The infra-red thermogram was observed before and after treatment. Results： The recovery and effective rates in the electroacupuncture group were 71.4% and 93.9%, whereas the rates in the medication groups were 42.6% and 87.2% （P〈0.01）. The temperature differences via the thermogram in the electroacupuncture and medication groups were 2.52℃ and 0.80℃ （P〈0.01）, indicating a significant difference. Conclusion： Both electroacupuncture and medication could obtain significant effect for acute lumbar sprain; however, electroacupuncture obtained a better overall effect and a more substantial temperature-raising effect in the thermogram than medication.
