BackgroundThe causes of chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF) are not clearly known, and there are no definitive treatments for them. Therefore, patients with CFS and ICF are interested in Oriental medicine or complementary and alternative medicine. For this reason, the effectiveness of complementary and alternative treatments should be verified. We investigated the effectiveness of two forms of acupuncture added to usual care for CFS and ICF compared to usual care alone.MethodsA three-arm parallel, non-blinded, randomized controlled trial was performed in four hospitals. We divided 150 participants into treatment and control groups at the same ratio. The treatment groups (Group A, body acupuncture; Group B, Sa-am acupuncture) received 10 sessions for 4 weeks. The control group (Group C) continued usual care alone. The primary outcome was the Fatigue Severity Scale (FSS) at 5 weeks after randomization. Secondary outcomes were the FSS at 13 weeks and a short form of the Stress Response Inventory (SRI), the Beck Depression Inventory (BDI), the Numeric Rating Scale (NRS), and the EuroQol-5 Dimension (EQ-5D) at 5 and 13 weeks.ResultsGroup A showed significantly lower FSS scores than Group C at 5 weeks (P = 0.023). SRI scores were significantly lower in the treatment groups than in the control group at 5 (Group A, P = 0.032; B, P <0.001) and 13 weeks (Group A, P = 0.037; B, P <0.001). Group B showed significantly lower BDI scores than Group C at 13 weeks (P = 0.007). NRS scores from the treatment groups were significantly reduced compared to control at 5 (Group A and B, P <0.001) and 13 weeks (Group A, P = 0.011; B, P = 0.002).ConclusionsBody acupuncture for 4 weeks in addition to usual care may help improve fatigue in CFS and ICF patients.Trial registrationClinical Research Information Service (CRIS) KCT0000508; Registered on 12 August 2012.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-015-0857-0) contains supplementary material, which is available to authorized users.

Background: Low back pain is a very common disease. Many patients with chronic low back pain (CLBP) have been treated by complementary and alternative medicine such as acupuncture (AT) treatment. A type of AT, thread embedding acupuncture (TEA), consists of a thread that can continually stimulate at the AT points and has mechanical and chemical effects. Although TEA was widely used in clinical practice, there was little evidence of its efficacy and safety for CLBP. Methods: This clinical trial was randomized, controlled, assessor-blinded, two-armed, parallel, and conducted in multiple centers. Four Korean medical institutions recruited 38 outpatients with CLBP. The participants were randomly allocated to a treatment group (TEA combined with AT) or a control group (only AT) in a 1:1 ratio. All participants received conventional AT twice a week for 8 weeks (16 sessions) at 15 AT points (GV3 and bilateral BL23, BL24, BL25, BL26, BL40, BL60, and EX-B5) and the treatment group participants additionally received TEA once a week for 8 weeks (8 sessions) on 10 AT points in the multifidus, spinal erector, and lumbar quadrate muscles. The primary outcome measure of this study was the change of visual analog scale (VAS) from baseline (0 week) to the end of intervention (8 weeks). Secondary outcome measures included clinically relevant improvement (minimal clinically important difference) and 3% to 50% decrease on VAS, disability level (Korean version of Roland and Morris disability questionnaire), quality of life (Korean version of European quality of life 5dimension), global assessment (patient global impression of change), economic analysis, credibility test, and safety assessment. Results: The treatment group showed a significant reduction in VAS scores when compared with the control group (–33.7 ± 25.1 vs –15.6 ± 17.0, P = .013). As for the secondary outcome measures, the treatment group showed significant difference in 50% decrease on VAS and patient global impression of change. There was no serious adverse event associated with TEA and AT. Conclusion: This clinical trial documents the efficacy and safety of TEA combined with AT for the management of CLBP.

BackgroundChronic non-specific low back pain is the most common medical problem for which patients seek complementary and alternative medical treatment, including bee venom acupuncture. However, the effectiveness and safety of such treatments have not been fully established by randomized clinical trials. The aim of this study is to determine whether bee venom acupuncture is effective for improving pain intensity, functional status and quality of life of patients with chronic non-specific low back pain.Methods/designThis study is a randomized, double-blinded, sham-controlled clinical trial with two parallel arms. Fifty-four patients between 18 and 65 years of age with non-radicular chronic low back pain experiencing low back pain lasting for at least the previous three months and ≥4 points on a 10-cm visual analog scale for bothersomeness at the time of screening will be included in the study. Participants will be randomly allocated into the real or sham bee venom acupuncture groups and treated by the same protocol to minimize non-specific and placebo effects. Patients, assessors, acupuncturists and researchers who prepare the real or sham bee venom acupuncture experiments will be blinded to group allocation. All procedures, including the bee venom acupuncture increment protocol administered into predefined acupoints, are designed by a process of consensus with experts and previous researchers according to the Standards for Reporting Interventions in Clinical Trials of Acupuncture. Bothersomeness measured using a visual analogue scale will be the primary outcome. Back pain-related dysfunction, pain, quality of life, depressive symptoms and adverse experiences will be measured using the visual analogue scale for pain intensity, the Oswestry Disability Index, the EuroQol 5-Dimension, and the Beck’s Depression Inventory. These measures will be recorded at baseline and 1, 2, 3, 4, 8 and 12 weeks.DiscussionThe results from this study will provide clinical evidence on the efficacy and safety of bee venom acupuncture in patients with chronic non-specific low back pain.Trial registrationThis study is registered with the United States National Institutes of Health Clinical Trials Registry: NCT01491321

BackgroundOsteoarthritis (OA) is an degenerative disease characterized by chronic joint pain. Complementary and alternative treatment such as acupuncture have been utilized to alleviate pain. The objective of this study was to investigate the analgesic mechanisms of electroacupuncture (EA) in the collagenase-induced osteoarthritis (CIOA) rat model.MethodsFour weeks after inducing CIOA by injecting collagenase solution into the left knee of 5-week-old male Sprague-Dawley rats, 2 Hz and 100 Hz EA on Zusanli (ST 36) was performed. The analgesic effect of EA was evaluated by the tail flick latency (TFL) and paw pressure threshold (PPT) tests. To investigate the analgesic mechanism, serotonergic and muscarinic cholinergic receptor agonists and antagonists were injected 20 min prior to EA and the resultant changes were evaluated by the TFL and PPT tests.ResultsEA on Zusanli (ST 36) demonstrated an analgesic effect in the CIOA rat model. The 2 Hz EA treatment showed a significantly greater analgesic effect than the 100 Hz treatment. The analgesic effect of 2 Hz EA was not strengthened by 5-HT1, 5-HT2, 5-HT3, and muscarinic cholinergic receptor agonist pretreatment, was blocked by 5-HT1, 5-HT3, and muscarinic cholinergic receptor antagonist pretreatment, but not blocked by 5-HT2 receptor antagonist pretreatment.ConclusionsIn the CIOA rat model, EA on Zusanli (ST 36) exhibited analgesic effects, and 2 Hz EA resulted in a significantly greater analgesic effect than 100 Hz EA. The analgesic effect of 2 Hz EA was reduced by pretreatment of 5-HT1 receptor, 5-HT3 receptor and muscarinic cholinergic receptor antagonists.
