不同频率电针刺激治疗神经根型颈椎病临床研究

Clinical study of electro-acupuncture therapy of different frequencies for the treatment of cervical spondylotic radiculopathy

目的观察不同频率电针刺激治疗神经根型颈椎病的临床疗效。方法采用随机对照方法,将94例患者随机分为电针Ⅰ组(31例)、电针Ⅱ组(31例)和电针Ⅲ组(32例)。各组均取大杼穴(双)、天柱穴(双)、颈夹脊穴(双),分别予2 Hz、50 Hz、100 Hz频率的电针治疗。各组均治疗14次,观察临床疗效,以及颈项部疼痛,枕顶部、上肢放射痛或麻木,椎间孔挤压试验变化情况。结果电针Ⅰ组、电针Ⅱ组、电针Ⅲ组总有效率分别为80.6%、83.9%、93.8%;电针Ⅲ组临床疗效优于电针Ⅰ组、电针Ⅱ组(P<0.05)。治疗前后组内比较,电针Ⅰ组颈项部疼痛积分明显减少(P<0.05),电针Ⅱ组颈项部疼痛和枕顶部、上肢放射痛或麻木积分明显减少(P<0.05),电针Ⅲ组颈项部疼痛和枕顶部、上肢放射痛或麻木及椎间孔挤压试验积分均明显减少(P<0.05)。治疗后,电针Ⅲ组与电针Ⅰ组比较,枕顶部、上肢放射痛或麻木和椎间孔挤压试验积分差异有统计学意义(P<0.05);电针Ⅲ组与电针Ⅱ组比较,椎间孔挤压试验积分差异有统计学意义(P<0.05)。电针Ⅱ组与电针Ⅰ组各指标差异均无统计学意义(P>0.05)。结论不同频率的电针刺激对神经根型颈椎病颈项部疼痛和枕顶部、上肢放射痛或麻木等均有一定的改善作用,其中以高频电针作用最为明显。

Objective To observe the clinical efficacy of electro-acupuncture therapy of different frequencies in treating cervical spondylotic radiculopathy.Methods Ninety-four cases were randomized into group Ⅰ（ n = 31）,group Ⅱ（ n = 31） and group Ⅲ（ n = 32）. These three groups were treated by electroacupuncture therapy on bilateral Dazhu（ BL11）,Tianzhu（ B 10） and neck Paravertebrals of 2 Hz,50 Hz and 100 Hz respectively. After treated for 14 times,we observed the clinical efficacy,neck pain,radiating pain and numbness of upper neck top and upper limbs,and squeezing test was conducted. Results The total effective rate was 80. 6% in group Ⅰ,83. 9% in group Ⅱ and 93. 8% in group Ⅲ; clinical efficacy of the in group Ⅲ was superior to that of the group Ⅰ and group Ⅱ（ P 〈 0. 05）. After treatment,the neck pain score was reduced in group Ⅰ（ P 〈 0. 05）,and scores of the neck pain,radiating pain or numbness of upper neck top and upper limbs were decreased markedly in group Ⅱ（ P 〈 0. 05）,and scores of the neck pain,radiating pain or numbness of upper neck top and upper limbs and squeezing test were reduced markedly（ P 〈 0. 05）. After treatment,there were significant differences in scores of radiating pain or numbness of upper neck top and upper limbs and squeezing test between group Ⅲ and group Ⅰ（ P 〈 0. 05）. There were significant difference in foramen intervertebrale squeezing test between group Ⅲ and group Ⅱ（ P 〈 0. 05）. No significant difference was found in indicators between group Ⅰ and group Ⅱ（ P 〉 0. 05）.Conclusion Electro-acupuncture therapy of different frequency can improve the symptoms and signs such as neck pain,radiating pain and numbness of upper neck top and upper limbs and so on,especially the high- frequency electro-acupuncture.
