曲垣穴位注射对神经根型颈椎病神经阈值的影响及疗效观察

Effect of Acupoint Injection at Quyuan(SI13) on the Vibrating Perception Threshold and Its Efficacy in Treating Cervical Spondylosis of Nerve Root Type

目的比较正常人与神经根型颈椎病人神经阈值的差别并观察曲垣穴穴位注射治疗神经根型颈椎病疼痛的临床疗效。方法选取63例神经根型颈椎病患者,随机分为治疗组35例和对照组28例。治疗组予曲垣穴穴位注射,对照组予常规华佗夹脊穴穴位注射。采用简化Mc Gill疼痛问卷表(MPQ),从疼痛分级指数(PRI)感觉分S、情绪分A、总分T、视觉模拟量表(VAS)及现有疼痛强度(PPI)等指标综合评定治疗前后疼痛缓解情况以量化疗效,并以其神经阈值(VPT)的变化作为参考。并采用国内华西康复中心制定的颈椎病功能评价量表对治疗组治疗效果进行分析。结果治疗后治疗组Mc Gill疼痛问卷表(MPQ)、VAS评分显著低于对照组,两组比较差异有统计学意义(P<0.05)。治疗组总有效率明显优于对照组,两组比较差异有统计学意义(P<0.05),同时神经阈值较治疗前有明显改善。结论曲垣穴穴位注射治疗神经根型颈椎病较常规华佗夹脊穴有更佳疗效。

Objective To compare the vibrating perception threshold （VPT） between normal subjects and subjects with cervical spondylosis of nerve root type, and to observe the clinical efficacy of acupoint injection at Quyuan （SI13） in releasing pain in cervical spondylosis of nerve root type.Method Sixty-three patients with cervical spondylosis of nerve root type were recruited and randomized into a treatment group of 35 cases and a control group of 28 cases. The treatment group received acupoint injection at Quyuan, and the control group received acupoint injection at Jiaji （EX-B2） points. The short-form McGill Pain Questionnaire （MPQ） was adopted. From the questionnaire, the Pain Rating Index （PRI）, sensory （S）, affective （A）, and total （T） pain rating indexes, Visual Analogue Scale （VAS）, and Present Pain Index （PPI） were used to comprehensively evaluate the pain improvement and to quantify the therapeutic efficacy, and the VPT was also considered. The Clinical Assessment Scale for Cervical Spondylosis （CASCS） by West China Rehabilitation Center was also used to analyze the result in the treatment group.Result After the intervention, the MPQ and VAS scores in the treatment group were significantly lower than those in the control group （P〈0.05）. The total effective rate of the treatment group was significantly higher than that of the control group （P〈0.05）. Meanwhile, the VPT was improved after the treatment.Conclusion Acupoint injection at Quyuan can produce a more significant efficacy than at Jiaji （EX-B2） in treating cervical spondylosis of nerve root type.
