电针对原发性骨质疏松症患者运动功能的影响:随机对照研究

Electroacupuncture on motor function in patients with primary osteoporosis: a randomized controlled trial

目的:观察电针对原发性骨质疏松症(POP)患者运动功能及肌肉状态的影响。方法:将60例女性POP患者随机分为观察组(30例,脱落1例)和对照组(30例,脱落1例)。在调整生活方式的基础上,对照组予钙尔奇口服,每天2粒,疗程4周。观察组在对照组基础上加电针治疗,穴取足三里、阳陵泉、肝俞、脾俞、肾俞等,予疏密波,频率为2 Hz/10 Hz,隔日1次,每周3次,疗程4周。比较两组患者治疗前后起立-行走计时测试(TUGT)时间与10米最大步行速度测试(10 m MWS)值,采用实时剪切波超声弹性成像技术(SWE)比较两组患者治疗前后俯卧位、坐位双侧多裂肌杨氏模量值。结果:治疗后,观察组患者TUGT时间较治疗前减少(P<0.01),且短于对照组(P<0.01);治疗后,观察组10 m MWS值较治疗前增加(P<0.05)。治疗后,观察组俯卧位、坐位双侧多裂肌杨氏模量值均较治疗前升高(P<0.01),除坐位左侧外,观察组多裂肌杨氏模量值均高于对照组(P<0.01,P<0.05)。结论:在口服钙尔奇基础上,电针可改善POP患者的运动功能及肌肉状态。

Objective To observe the effect of electroacupuncture on motor function and muscle state in patients with primary osteoporosis(POP). Methods A total of 60 female patients with POP were randomized into an observation group(30 cases, 1 case dropped off) and a control group(30 cases, 1 case dropped off). On the basis of adjusting lifestyle, caltrate was given orally in the control group, 2 pills a day for 4 weeks. On the basis of the treatment in the control group,electroacupuncture was applied at Zusanli(ST 36), Yanglingquan(GB 34), Ganshu(BL 18), Pishu(BL 20), Shenshu(BL 23),etc. in the observation group, with disperse-dense wave of 2 Hz/10 Hz in frequency, once every other day, 3 times a week for 4 weeks. The time of timed up-and-go test(TUGT) and the value of 10 m maximal walking speed(10 m MWS) before and after treatment were compared in the two groups, and the Young′s modulus values of bilateral multifidus muscles in prone position and sitting position before and after treatment were compared by real-time shear wave elastography(SWE) in the two groups.Results After treatment, the TUGT time was decreased compared before treatment in the observation group(P<0.01), and that in the observation group was shorter than the control group(P<0.01). After treatment, the value of 10 m MWS test was increased compared before treatment in the observation group(P<0.05). After treatment, the Young′s modulus values of bilateral multifidus muscles in prone position and sitting position were increased compared before treatment in the observation group(P<0.01);except for the left side in sitting position, the Young′s modulus values of multifidus muscles in the observation group were higher than those in the control group(P<0.01, P<0.05). Conclusion On the basis of oral caltrate, electroacupuncture can improve the motor function and muscle state in patients with POP.
