针刺董氏奇穴和传统穴位治疗泰国老年慢性腰痛患者的疗效比较

Comparison of the efficacy of acupuncture at the TUNG’s extra points and the traditional Chinese medicine points for elderly patients with chronic low back pain in Thailand

目的比较针刺董氏奇穴和中医传统穴位治疗泰国老年慢性腰痛(CLBP)患者的疗效。方法采用单盲、随机对照试验设计,纳入84名慢性腰痛老年患者。所有患者被随机分为两组,一组接受董氏奇穴针刺治疗,另一组接受传统中医(TCM)穴位针刺治疗。每次治疗30 min,连续治疗7 d。治疗前后进行数字评定量表(NRS)评分、背部活动度(BROM)及背部力量的测量和比较。结果与同组治疗前比较,治疗后两组NRS评分降低,BROM增加(P<0.05),但腰部力量无统计学差异。组间比较,治疗后两组NRS评分、前屈及右侧屈BROM、腰部力量方面的差异均无统计学意义(P>0.05),而两组BROM在后伸(P<0.01)和左侧屈(P<0.05)方面的差异有统计学意义。结论针刺董氏奇穴在降低腰部疼痛NRS评分,增加腰部力量,以及增加腰前屈及右侧屈活动度方面与针刺TCM穴位的效果相当.针刺传统穴位在增加腰后伸及左侧屈活动度方面效果更佳;针刺董氏奇穴适合老年CLBP患者,应得到支持推广。

Objective To compare the efficacy of acupuncture at TUNG’s extra points and traditional Chinese medicine(TCM)points for elderly patients with chronic low back pain(CLBP)in Thailand.Methods A single-blinded,randomized controlled trial with 84 elderly volunteers with CLBP was designed.The patients were randomly assigned either to the group getting acupuncture at TUNG’s extra points or to the group getting acupuncture at TCM points.The treatment period was 30 min per session for seven consecutive days.Before and after treatment,the score of the numeric rating scale(NRS),the back range of motion(BROM),and the back strength were measured and compared.Results After treatment,both groups were found with decreased NRS scores and increased BROM(P<0.05),but with no statistical difference in their back strength in comparison with that before treatment in the same group(P>0.05).Regarding the between-group comparisons,no significant differences were found in the NRS score or BROM in the direction of forward flexion and right lateral flexion or the back strength after treatment(P>0.05).However,statistical differences were found in the BROM in directions of back extension(P<0.01)and left lateral flexion(P<0.05).Conclusion Acupuncture at TUNG’s extra points can decrease the low back pain NRS score and increase the back strength and the BROM in directions of forward flexion and right lateral flexion,equivalent to acupuncture at TCM points.Acupuncture at TCM points has a better effect in increasing the BROM in directions of back extension and left lateral flexion;acupuncture at TUNG’s extra points is suitable for elderly CLBP patients,and it should be supported and promoted.
