The aim of this systematic review was to determine how effective acupuncture or electroacupuncture (acupuncture with electrical stimulation) is in treating poststroke patients with spasticity. We searched publications in Medline, EMBASE, and the Cochrane Library in English, 19 accredited journals in Korean, and the China Integrated Knowledge Resources Database in Chinese through to July 30, 2013. We included randomized controlled trials (RCTs) with no language restrictions that compared the effects of acupuncture or electroacupuncture with usual care or placebo acupuncture. The two investigators assessed the risk of bias and statistical analyses were performed. Three RCTs in English, 1 in Korean, and 1 in Chinese were included. Assessments were performed primarily with the Modified Ashworth Scale (MAS). Meta-analysis showed that acupuncture or electroacupuncture significantly decreased spasticity after stroke. A subgroup analysis showed that acupuncture significantly decreased wrist, knee, and elbow spasticity in poststroke patients. Heterogeneity could be explained by the differences in control, acupoints, and the duration after stroke occurrence. In conclusion, acupuncture could be effective in decreasing spasticity after stroke, but long-term studies are needed to determine the longevity of treatment effects.

Introduction. Although combination therapy with herbal medicine and probiotics is gaining popularity for controlling diarrhea-dominant irritable bowel syndrome (D-IBS) symptoms, few studies have investigated its clinical effects.Materials and Methods. Fifty-three patients with D-IBS were randomly allocated into 1 of the following 4 groups: herbal medicine (Gwakhyangjeonggisan; GJS) plus probiotics (Duolac7S; DUO), GJS plus placebo DUO, placebo GJS plus DUO, and placebo GJS plus placebo DUO. The study period consisted of a 2-week run-in, 8 weeks of administration, and 2 weeks of follow-up. The primary outcomes were weekly adequate relief (AR) of overall IBS symptoms and the proportion of responders (PR) during the administration period. The secondary outcomes included individual IBS symptoms, stool assessment, and quality of life. Changes of intestinal microbiota and intestinal permeability were also analyzed.Results and Discussion. Weekly AR was not different among the 4 groups throughout the treatment period. However, the 3 treatment groups exhibited significant improvements in PR compared to the findings in the placebo group. In the intestinal microbiota assessment, herbal medicine and probiotics synergistically increased beneficial bacteria counts.Conclusion. Combination therapy with herbal medicine and probiotics appears to relieve overall IBS symptoms by synergistically increasing beneficial intestinal microbe counts.

The side effects associated with breast cancer treatments often reduce the patients’ quality of life. The effectiveness of acupuncture-related therapies and herbal medicine in managing the side effect is not fully understood. The study included clinical studies published in the 10 years since 2011 and analyzed the effectiveness of the therapies for managing side effects of anticancer treatment. The databases of MEDLINE via PubMed, CENTRAL, EMBASE, OASIS, and NSDL were searched. Thirty studies, including 13 (43.3%) randomized controlled trials (RCTs), 12 (40.0%) before-and-after studies, three (10.0%) case series, one (3.3%) case report, and one (3.3%) non-RCT, were included in this review. The main symptoms identified were aromatase inhibitors-induced arthralgia (AIA), lymphedema, and chemotherapy-induced peripheral neuropathy (CIPN). The types of acupuncture-related therapies applied included manual acupuncture, electro-acupuncture, moxibustion, and electro-moxibustion. In ten studies, eight herbal medications were administered. The Brief Pain Inventory-Short Form (BPI-SF) and Functional Assessment of Cancer Therapy-General (FACT-G) and -Breast (FACT-B) were frequently used to evaluate pain and QoL, respectively. Most studies suggested beneficial effects of acupuncture and herbal medicine on managing pain, daily function, and quality of life in patients going through AIA, CIPN, and/or lymphedema, with mild side effects. The scoping review implies the potential of CAM therapies as promising interventions for managing symptoms which otherwise lack alternative management options, and for improving the quality of life of breast cancer patients.

The purpose of this study is to evaluate the efficacy and safety of myofascial-meridian release acupuncture (MMRA) in the treatment of chronic neck pain compared with sham acupuncture. A protocol for a randomized, patient- and assessor-blinded, sham controlled parallel trial is presented. Seventy-four participants with a ≥3 month history of neck pain and a score of ≥4 on the 11-point pain intensity numerical rating scale (PI-NRS) will be randomly assigned to the MMRA group (n = 37) or sham acupuncture group (n = 37). The participants will receive the MMRA treatment or sham acupuncture treatment twice per week for 4 weeks. The primary outcome is the mean change in the PI-NRS (0 = no pain and 10 = worst possible pain, 11-point Likert scale) from baseline to 4 weeks. The secondary outcomes are the mean change from baseline on the clinical relevance of the pain (ratio of changes greater than 1.5 or with percentiles greater than 30 % and 50 % in the PI-NRS), function (Neck Disability Index and Cervical Range of Motion), autonomic and psychometric measurements (Heart Rate Variability and Perceived Stress Scale), quality of life (EuroQol), global assessment (Patient Global Impression of Change), semi-objective outcomes (pressure pain threshold, consumption of rescue medicine and days of restricted activity) and immunologic/stress biomarkers. Adverse events will be evaluated at every visit. The results of this trial will provide evidence to confirm the efficacy and safety of acupuncture for chronic neck pain. The trial is registered with the Clinical Research Information Service (CRiS), Republic of Korea: KCT0001573 .
