  • Background: To investigate the antidiabetic effects of hydrolyzed ginseng extract (HGE) for Korean participants in an 8-wk, randomized, double-blinded, placebo-controlled clinical trial. Methods: Impaired fasting glucose participants [fasting plasma glucose (FPG) ${\geq}5.6mM$ or < 6.9mM who had not been diagnosed with any disease and met the inclusion criteria were recruited for this study. The 23 participants were randomly divided into either the HGE (n = 12, 960 mg/d) or placebo (n = 11) group. Outcomes included measurements of efficacy (FPG, postprandial glucose, fasting plasma insulin, postprandial insulin, homeostatic model assessment-insulin resistance, and homeostatic model assessment-${\beta}$) and safety (adverse events, laboratory tests, electrocardiogram, and vital signs). Results: After 8 wk of HGE supplementation, FPG and postprandial glucose were significantly decreased in the HGE group compared to the placebo group. No clinically significant changes in any safety parameter were observed. Our study revealed that HGE is a potent antidiabetic agent that does not produce noticeable adverse effects. Conclusion: HGE supplementation may be effective for treating impaired fasting glucose individuals.

  • Objective This study was performed to investigate whether Bee Venom Pharmacopuncture(BVP) could be a more effective modality than Warm Needling(WN) in relieving pain and symptoms of knee osteoarthritis(OA). Design Prospective, randomized and controlled clinical trial. Setting Single center trial in Korea Patients 49 volunteers with knee OA participated in the study. All the participants were screened through an inclusion and exclusion criteria. 33 participants were completed the clinical trial. Intervention The subjects were randomly assigned to one of two groups. One group received BVP(n=18), while the other group received WN(n=15). Sixteen sessions of BVP or WN were given at the pain region of the problematic knee for 8 weeks. Primary outcome measure is the Korean translation of Western Ontario and McMaster Universities Osteoarthritis Index scores(Korean WOMAC, KWOMAC). Secondary outcome measure is the physical health scores based on the 36-Item Short-Form Health Survey(SF-36) and Patient Global Assessment(PGA). KWOMAC and SF-36 were measured third (baseline, 4 and 8 weeks). PGA was measured twice(4 and 8 weeks). Results BVP group showed significant decrease compared to WN group in pain, function and total scores of KWOMAC according to the Mann-Whitney U-test. In the PGA, BVP group, compared to WN group, showed a significant increase. Conclusions BVP was more effective in relieving pain of knee OA than WN. These findings suggest that BVP is a promising alternative for treating knee OA.

  • Purpose: The purpose of this study was to investigate the effects of Wheel of Wellness counseling on wellness lifestyle, depression, and health-related quality of life in community dwelling elderly people. Methods: A parallel, randomized controlled, open label, trial was conducted. Ninety-three elderly people in a senior welfare center were randomly assigned to two groups: 1) A Wheel of Wellness counseling intervention group (n=49) and 2) a no-treatment control group (n=44). Wheel of Wellness counseling consisted of structured, individual counseling based on the Wheel of Wellness model and provided once a week for four weeks. Wellness lifestyle, depression, and health-related quality of life were assessed pre-and post-test in both groups. Results: Data from 89 participants were analyzed. For participants in the experimental group, there was a significant improvement on all of the wellness-lifestyle subtasks except realistic beliefs. Perceived wellness and depression significantly improved after the in the experimental group (n=43) compared to the control group (n=46) from pre- to post-test in the areas of sense of control (p =.033), nutrition (p =.017), exercise (p =.039), self-care (p <.001), stress management (p =.017), work (p =.011), perceived wellness (p =.019), and depression (p =.031). One participant in the intervention group discontinued the intervention due to hospitalization and three in the control group discontinued the sessions. Conclusions: Wheel of Wellness counseling was beneficial in enhancing wellness for the community-dwelling elderly people. Research into long-term effects of the intervention and health outcomes is recommended.

  • Objectives The study was conducted to evaluate the acupuncture treatment for burns by reviewing international randomized controlled studies and case controlled studies. Methods In the review, ten academic literature archives; NDSL, OASIS, PubMed, Cochrane library, CNKI, WANFANG, CINAHL, J-STAGE, CiNii, and EMBASE were used as the main databases to search for the randomized controlled trials or the case controlled trials about acupuncture treatment of burns using the keywords "burns AND acupuncture", "burn AND acupuncture", and "scald AND acupuncture". Results Initially, a total of 852 studies were founded except duplicate studies. 801 studies were excluded after screening of title and abstract. After reviewing 51 papers, a total of four randomized controlled trials and two case controlled trials were selected. These studies were analyzed by year, subjects, treatment intervention, evaluation criteria, treatment effect, adverse events, and 'Risk of Bias' assessment for randomized studies and non-randomized studies. From the six papers out of 51 papers those were reviewed, patients with burns were divided into two groups. The experimental group received acupuncture treatment, while the control group did not. The results of the completed studies have shown that the experimental group receiving acupuncture treatment demonstrated significant improvement compared to the control group, and there was no serious adverse events. Conclusions According to some of the studies, acupuncture in burn treatment is worth to try. However, additional well-designed randomized controlled studies will be required to justify the effectiveness of acupuncture treatment of burns.

  • The use of acupuncutre has been increased worldwide, and large number of researches on acupuncture with improved quality has been conducted. Nevertheless, results of acupuncture treatment in those research tend to show mixed results, while many patients continuously seek acupuncture treatment as an adjuvant or alternatives for their health. Researchers and clinicians relevant to acupuncture are faced at this problematic discrepancy between the results of acupuncture in clinical trial including an randomized controlled trial and those of day-to-day clinical practice. The methodology of pragmatic clinical trial seems to be one of the promising research tools administering this problem especially in the area of complementary alternative medicine and traditional Korean medicine. In this study we first reviewed articles on the pragmatic clinical trial, summarized the essential concepts of 'explanatory' clinical trial 'pragmatic' clinical trial and then presented recent recommendations and arguments on this issue. We also analyzed and compared two similar pragmatic clinical trial protocols to show the readers the complexity of research designing. We hope more researchers in traditional Korean medicine will be interested in the methodology of pragmatic clinical trials and this study will serve to produce various high-quality clinical trials.

  • Objectives : This is a pilot study for a large randomized controlled trial to investigate the efficacy and safety of a newly developed contrast therapy device-- alternating topical heat and cold -- for patients with chronic low back pain. The main objective of this study is to confirm the feasibility of the study design. Methods : The design was a randomized, 2-arm, parallel-group, single-blind, placebo controlled trial. Patients in each group received real or sham contrast therapy in an acupuncture point 10 times over four weeks. The primary outcome measure was pain intensity on a 100-mm visual analogue scale (VAS). The secondary outcomes were back-related dysfunction based on the Oswestry Disability Index (ODI), the Roland-Morris disability questionnaire (RMDQ), and range of motion of lumbar spine based on the modified Schober test (mSchober test), Finger-to-Floor distance (FTF distance), and Finger-to-Thigh distraction (FTT distraction). Results : A total of 30 subjects with chronic low back pain were randomly assigned to a contrast therapy group (n=15) or a sham group (n=15). A repeated-measures analysis of variance showed statistically significant group time interaction for VAS, RMDQ, mSchober test and FTF distance (p<0.05). The treatment group showed significant improvement in pain intensity and functional disability as compared to the sham group. Conclusion : Contrast therapy may be an effective and safe treatment for chronic low back pain.

  • Objective : To test the hypotheses that individualized traditional Korean acupuncture improves pain and disability in patients with osteoarthritis of the knee and that benefits remain after stopping treatment more so than is the case for standardized minimal acupuncture. Design : Randomized single blind controlled trial with two intervention arms (individualized traditional Korean acupuncture, standardized minimal acupuncture) of six weeks' duration and three months follow-up. Setting : Acupuncture interventions were applied by two training doctors in the Department of Acupuncture and Moxibustion in a 1000-bed hospital. Assessment of the result was performed in a university-based laboratory. Participants : 50 patients with symptoms of knee osteoarthritis as diagnosed by an orthopedist. Intervention : Individualized traditional Korean acupuncture or standardized minimal acupuncture for six weeks. Main outcome measures: Primary outcome measure was pain as measured by the visual analogue scale. Secondary measures of pain and disability included the Western Ontario and McMaster Universities (WOMAC) index, Short Form-36 (SF-36), Lequesne Functional Index (LFI) score and Korean version of Health Assessment Questionnaire (KHAQ). Discussion : This paper presents detail on the rationale, design, methods and operational aspects of the trial.

  • Background: Related to escalating health care costs and the questionable effectiveness of multiple interventions including lumbar facet joint interventions, cost effectiveness or cost utility analysis has become the cornerstone of evidence-based medicine influencing coverage decisions. Methods: Cost utility of therapeutic lumbar facet joint nerve blocks in managing chronic low back pain was performed utilizing data from a randomized, double-blind, controlled trial with a 2-year follow-up, with direct payment data from 2016. Based on the data from surgical interventions, utilizing the lowest proportion of direct procedural costs of 60%, total cost utility per quality adjusted life year (QALY) was determined by multiplying the derived direct cost at 1.67. Results: Patients in this trial on average received $5.6{\pm}2.6$ procedures over a period of 2 years, with average relief over a period of 2 years of $82.8{\pm}29.6$ weeks with $19{\pm}18.77$ weeks of improvement per procedure. Procedural cost for one-year improvement in quality of life showed USD $2,654.08. Estimated total costs, including indirect costs and drugs with multiplication of direct costs at 1.67, showed a cost of USD $4,432 per QALY. Conclusions: The analysis of therapeutic lumbar facet joint nerve blocks in the treatment of chronic low back pain shows clinical effectiveness and cost utility at USD $2,654.08 for the direct costs of the procedures, and USD $4,432 for the estimated overall cost per one year of QALY, in chronic persistent low back pain non-responsive to conservative management.
