Objective: To observe the therapeutic efficacy of Fu's subcutaneous needling(FSN) in treating scapulohumeral periarthritis(SP).Methods: Eighty patients with SP were randomly divided into an observation group and a control group, 40 cases in each group. Patients in the observation group received FSN treatment while those in the control group received conventional acupuncture treatment. Visual analogue scale(VAS) and range of motion(ROM) were observed before and after the treatment, and the therapeutic efficacy was also evaluated.Results: After the treatment, the VAS scores decreased significantly in the two groups, and the VAS score in the observation group was significantly lower than that in the control group(P〈0.01). After the treatment, the ROM increased significantly in both groups(both P〈0.01), and the ROM in the observation group was significantly higher than that in the control group(P〈0.01). The recovery rate and the total effective rate in the observation group were respectively 40.0% and 95.0%,significantly higher than 12.5% and 77.5% in the control group(P〈0.01, P〈0.05).Conclusion: FSN can effectively relieve pain and improve the joint motion in treating SP, thus offering a novel option to the treatment of this kind of musculoskeletal disorder. 展开更多

Objective: To observe the clinical efficacy of warm needling moxibustion plus tuina in treating knee osteoarthritis (KOA) due to cold-dampness blocking collaterals. Methods: Forty-eight KOA patients were randomized into 2 groups by their visiting sequence, 24 cases in each group. The treatment group was intervened by warm needling moxibustion plus tuina, while the control group was treated with acupuncture plus tuina. The two groups were both treated once a day, 30 min for each session, 10 d as a treatment course, totally for 3 treatment courses. The visual analogue scale (VAS) and Lysholm knee scoring scale (LKSS) were observed before and after the treatment to evaluate the clinical efficacy. Results: After 3 treatment courses, the VAS and LKSS scores were significantly changed in the two groups (P〈0.01), and the between-group differences were also statistically significant (P〈0.01). The markedly-effective rate was 83.3% in the treatment group versus 66.7% in the control group, and the difference was statistically significant (P〈0.05). Conclusion: Warm needling moxibustion plus tuina can produce a more significant efficacy than acupuncture plus tuina in treating KOA due to cold-dampness blocking collaterals. 展开更多

Objective: To observe the clinical efficacy of balance-impact tuina therapy for lumbar intervertebral disc herniation (LIDH). Methods: A total of 118 eligible LIDH patients were randomized into an observation group and a control group by the random number table method, with 59 cases in each group. The observation group was intervened by balance-impact tuina therapy, while the control group was intervened by conventional tuina therapy, both for consecutive two weeks. The scores of visual analog scale (VAS), Oswestry disability index (ODI)Z quality of life questionnaire-core 30 (QOL-C30) were observed before and after treatment;the relapse rate was estimated at the sixth month and twelfth month following the treatment. The data were statistically an a lyzed. Results: After intervention, the total effective rate was 96.6% in the observation group versus 91.5% in the control group, and the between-group differenee was statistically significant (P<0.05). The VAS and ODI scores declined significantly after treatment in both groups (all Pv0.05), and the observation group was markedly lower than the control group (P<0.05, P<0.01). The QOL-C30 score in creased significantly after treatme nt in both groups (both P<0.05), and the observatio n group was markedly higher than the control group (P<0.05). The relapse rates at the post-treatment sixth month and twelfth month in the observation group were lower than those in the control group (P<0.05, P<0.01). Conclusion: Compared with the conventional tuina therapy, the balance-impact tuina therapy shows advantage in lessening pain, improving the function and enhancing the quality of life in the treatment of LIDH, and it has a lower relapse rate. Thus, this therapy is worth promoting in clinic. 展开更多
