To observe the clinical effects of Shu-acupuncture method in Nei Jing(Classic of Internal Medicine) in the treatment of shoulder and arm pain. A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing(Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). The therapeutic effect of Shu-acupuncture method in Nei Jing(Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain. 观察《内经》輸刺法为主治疗肩臂痛的临床疗效。 将90例肩臂痛患者随机分为观察组和对 照组, 每组45例。观察组采用《内经》输刺法治疗, 对照组采用常规针刺治疗。两组均每日治疗1次, 5次为1疗程, 疗程间休息2 d。治疗3个疗程后进行疼痛的视觉模拟量表(VAS)评分, 并比较两组的临床疗效。 治疗后, 两 组VAS评分均与本组治疗前有统计学差异(均P<0.01); 观察组VAS评分低于对照组, 组间差异有统计学意义 (P<0.05)。观察组总有效率为100.0%, 对照组为91.1%, 两组总有效率差异具有统计学意义(P<0.05)。 《内经》输刺法治疗肩臂痛疗效优于常规针刺。
