Objectives: purpose of this study was to evaluate the effectiveness of cupping therapy for frozen shoudler through systemic review and meta-analysis
Methods: The effect of cupping therapy for frozen shoulder was constructed as a key question to search randomized clinical trials(RCTs) in 15 databases(KoreaMed, Kmbase, NDSL, KOAR, KISS, OASIS, Koreantk, PubMed, Embase, Ovid-Medline, Cochrane CENTRAL, CINHAL, CNKI, Wanfang, VIP database) without type of publication restriction and language up to October 2020. Cochrane's Risk of bias tool was used for evaluate the quality of literature, and RevMan 5.4 was used for the meta-analysis.
Result: A total of 907 papers were retrieved from databases and the final 23 random control trials (RCT) were selected through the primary and secondary selection, exclusion processes.
There were 8 studies comparing cupping with acupuncture and acupuncture, 3 studies comparing cupping with warming acupuncture and warnming acupuncture, 2 studies comparing cupping with electronic acupuncture and electronic acupuncture, 1 study comparing cupping and NSAIDSs, 1 study comparing cupping with exercise therapy and exercise therapy, 1 study comparing cupping with scraping and scraping, 1 study comparing cupping with acupotomy and acupotomy, 1 study comparing cupping with acupuncture and microwave with acupuncture, 1 study comparing cupping with Fire needling and Fire needling, 1 study comparing cupping with nursing and nursing, 1 study comparing cupping with H-med and TDP injection with H-med, 1 study comparing cupping with laser therapy and acupuncture with laser therapy.
In most of the evaluation indexes used in each study, cupping therapy for frozen shoulder was statistically significant and no side effects were reported in the included studies. In the studies included anlaysis, performance bias was especially high risk of bias and the bias was generally uncertain or high in all studies.
A meta-analysis of effective rate in 8 studies comparing cupping with acupuncture and acupuncture showed a statistically significant effect of cupping treatment with RR 1.28(8 studies, n=576, RR 1.28; 95% CI 1.13 to 1.45, Z=3.90, P<0.0001). and the result of meta-analysis of 3 studies' effective rate comparing cupping with warming acupuncture and warming acupuncture showed a statistically significant effect of cupping treatment with RR 1.21(3 studies, n=252, RR 1.21; 95% CI 1.10 to 1.33, Z=3.92, P<0.0001 ) and the result of meta-analysis of 2 studies' effective rate comparing cupping with electronic acupuncture and electronic acupuncture showed a statistically significant effect of cupping treatment with RR 1.17(2 studies, n=178, RR 1.17; 95% CI 1.01 to 1.36, Z=2.12, P=0.03).
Conclusion: Cupping therapy was effective in patients with frozen shoulder. However because of the high or uncertain risk of bias in the quality of the included studies, the interpretation and applicability of this study seems to be limited. It is thouth that future randomized controlled trials will need to be desighned and performed by reviewing ways to minimize bias, and Research applying such studies should be continued.
