OBSERVATION ON THE THERAPEUTIC EFFECT OF ACUPUNCTURE TREATMENT OF 123 CASES OF SCAPULOHUMERAL PERIARTHRITIS

Objective: To observe the therapeutic effect of Qinglong Bai Wei Zhen Fa (Green Dragon Shaking Tail Needling) in the treatment of scapulohumeral periarthritis. Methods: A total of 231 cases of scapulohumeral periarthritis patients were randomized into treatment group (n=123) and control group (n=108). In treatment and control groups, Jianyu (LI 15), Jianqian and Jianhou were used as the main acupoints and stimulated with Green Dragon Shaking Tail Needling and conventional needling separately. Additionally, in control group, Waiguan (TE 5) and Binao (LI 14) were supplemented. The treatment was given once daily, with 10 days being a therapeutic course, 2 courses altogether. Results: After the first course of treatment, in treatment and control groups, the cured, the markedly improved, the effective and ineffective cases were 49 and 12, 61 and 33, 11 and 40, 2 and 23, with the total effective rates being 98.4% and 78.7% respectively. There was a marked difference between two groups in the therapeutic effect (P<0.05). Following 2 courses of treatment, the cured, the markedly improved, the effective and ineffective cases were 66 and 21, 47 and 41, 10 and 39, 0 and 7, with the total effective rates being 100% and 93.5% separately. No significant difference between two groups in the total effective rates, but the cure rate of treatment group was strikingly higher than that of control group. Conclusion: Green Dragon Shaking Tail Needling is significantly superior to that of conventional needling in the treatment of scapulohumeral periarthritis.

Modified green dragon swaying its tail needling manipulation for treatment of knee osteoarthritis

Objective To compare the difference in the effect of modified green dragon swaying its tail needling manipulation and common needling manipulations on the overall rating of pain of patients with knee osteoarthritis, and to evaluate the advantages of modified green dragon swaying its tail needling manipulation for. Methods Ninety-five patients with knee osteoarthritis were divided into 2 groups according to the random number table method with 48 patients in the modified green dragon swaying its tail group（group special manipulation, SM group for short） and 47 patients in the common acupuncture group（group convention needling, CN group for short）, and different acupuncture manipulations were applied in the two groups. Internationally recognized Simplified Mc Gill Pain Questionnaire（SF-MPQ） scale used for description and measurement of pain was applied to evaluate the pain degree, including pain rating index（PRI）, visnal analogue scale（VAS）and present pain intensity（PPI）. The index of severity for osteoarthritis（ISOA） was adopted for evaluation of clinical efficacy. Results（1） In SM group, the scores of PRI, VAS and PPI were 6.63±4.67, 2.23±1.45 and 0.65±1.32, respectively, after treatment, and in CN group, the scores of PRI, VAS and PPI were 13.32±7.96, 4.34±1.79 and 2.28±1.21, respectively, the scores decreased in the two groups after treatment（all P〈0.05）, and the improvement in SM group was superior to that in CN group（all P〈0.01）.（2） The clinical cure rate in SM group was 52.08%, and the total effective rate was 97.92%, the clinical cure rate in CN group was 25.53%, and the total effective rate was 85.10%. The comparison of clinical cure rate in the two groups showed that P〈0.01. Conclusion The SM group is obviously superior to CN group in the improvement of overall rating of pain of patients. It is indicated that modified green dragon swaying its tail acupuncture therapy can effectively relieve the pain of patients with knee osteoarthritis, which was worthy of popularization and application with definite clinical efficacy
