Objectives The objective of this study is to provide the evidence of the effectivness of herbal medicine for frozen shoulder. Methods 2 Korean medical on-line databases (Oriental Medicine Advanced Searching Integrated System, Korean Traditional Knowledge), and 3 foreign databases (Pubmed, Cochrane library, China National Knowledge Infrastructure) were searched to find articles concerning herbal medicine for frozen shoulder. We selected randomized controlled trials (RCTs). Several repeated articles and those not relevant to the topic were excluded, as well as review articles and commentaries. The methodological quality of RCTs were evaluated using the Cochrane risk of bias tool and meta-analyes were perfomed. Results Total 474 studies were founded and 22 RCTs were selected for systematic review. Efficiency rate was used as the primary evaluation method. Almost studies reported that herbal medicine has significant effect on pain reduction, increasing shoulder function on frozen shoulder. 3 studies comparing herbal medicine and chuna with chuna and 3 studies comparing herbal medicine with ibuprofen were included in the meta-analysis. At herbal medicine and chuna with chuna meta-analysis, it showed positive results of herbal medicine for efficiency rate (risk ratio: 1.18, 95% confidence interval: 1.09-1.27, p<0.0001). At herbal medicine with ibuprofen medta-analysis, it showed positive results of herbal medicine for efficiency rate (risk ratio: 1.15, 95% confidence interval: 1.05-1.27, p=0.003). Conclusions The studies showed that herbal medicine can significantly effective on frozen shoulder. However, the risk of bias in RCTs were evaluated as uncertain. In the future, further well-designed RCTs are needed to prove the effectiveness of herbal medicine for frozen shoulder and reduce the risk of bias.
Objectives: The purpose of this study was review the current clinical studies about the effect of Korean traditional medicine treatment for meniscus injury.Methods: Clinical studies on Korean traditional medicine treatment of meniscus injury were searched through 11 online databases. We analyzed the authors, publication year, country, study design, subjects, treatment methods, treatment effects, evaluation tools and adverse events of the selected studies.Results: 23 studies which included 9 randomized controlled trials, 8 case reports, 4 retrospective observational studies, 2 non-randomized controlled trials were selected through the databases. A total of 9 Korean traditional medicine treatments were used, among them, acupuncture treatment was the most used. The most commonly used outcome was effective rate.Conclusions: Through this study, we could confirm that Korean traditional medicine is an effective treatment for meniscus injury. It was suggested that various clinical studies on the effects of Korean traditional medicine for meniscus injury are needed and it is necessary to establish more scientific evidence through studies with a high level of evidence.
