Therapeutic Efficacy and the Impact of the "Dose" Effect of Acupuncture to Treat Sciatica: A Randomized Controlled Pilot Study.

ABSTRACT: Purpose:To investigate the required sample size for and feasibility of a full-scale randomized controlled trial examining the impact of the "dose" effect of acupuncture in treating sciatica. Patients and methods:Fifty-seven patients with sciatica, aged 35-70 years, were recruited and screened. Thirty-one participants were randomly assigned to receive "low-dose" manual acupuncture (MAL) (n= 15) or "high-dose" manual acupuncture (MAH) (n=16). The acupuncture treatment was administered twice weekly for 4 weeks. The primary outcome was the visual analog scale (VAS) score at baseline and after 4 weeks of acupuncture treatment. Secondary outcomes included the Roland Disability Questionnaire for Sciatica (RDQS), the Sciatica Bothersomeness Index (SBI), and the World Health Organization Quality of Life in the Brief Edition (WHOQOL-BREF) scores at baseline and after 4 weeks of acupuncture treatment. Results:Thirty patients completed the study. For all patients, acupuncture achieved significant improvement in the VAS (5.48±2.0, p<0.001), RDQS (3.18±2.83, p=0.004), and SBI (2.85±3.23, p=0.008) scores, but not in the WHOQOL-BREF scores. In the between-group analysis, the assessed scales showed no significant differences between the MAL and MAH groups. However, based on the level of chronicity, the MAH group demonstrated greater improvement in the outcomes and a significant benefit in the physical subscale of the WHOQOL-BREF (p<0.05). Conclusion:Results of this pilot study indicate that acupuncture is safe and may effectively relieve symptoms and disability in patients with non-acute sciatica. MAL was as effective as MAH in treating sciatica. A subsequent trial with a larger sample size (estimated at n=96) is required to confirm whether patients with a high level of chronicity would benefit from MAH treatment.

Project description:Background and motivationThe effectiveness of using acupuncture to treat migraine is rarely and even suspectedly reported in the literature. In this article, we report the design and the protocol of a randomized controlled large-scale trial to treat migraine using acupuncture, aiming at testifying it is effective to use acupuncture to treat migraine. We demonstrate also that the effectiveness of the treatment may vary due to using acupoints of different meridians or different acupoints of one meridian.Methods and designA multi-center randomized controlled trial is currently undergoing, with three acupoints treatment groups and one non-acupoints control group. The acupuncture treatment consists of 20 sessions per patient with a observation period of 20 weeks. In total, 480 patients with migraine are registered in this study within 8 hospitals in China from March 2008 to June 2009. These patients are randomly assigned to receive one of the following four acupoints treatment groups, i.e. 1) specific acupoints of Shaoyang meridians (120 patients), 2) non-specific acupoints of Shaoyang meridians (120 patients), 3) acupoints of other meridians (120 patients); or 4) non-acupoints control group (120 patients). The main outcome measurement in this trial is the effect comparison achieved among these four groups in terms of number of days with migraine and intensity of migraine during and after the baseline phase, i.e. the first 4 weeks before randomization and 4, 8 and 16 weeks after randomization. The intensity of headache including headache intensity grade (0-3) and visual analogue scale (VAS) score will also be used in this study. In addition, the differences of Migraine-Specific Quality-of-Life Questionnaire (MSQ) and Transcranial Doppler Sonography (TCD) before and after randomization are also used as the secondary outcome measurement.DiscussionThe result of this trial (which will be available in 2009) will demonstrate the efficacy of using acupuncture to treat migraine, and verify whether the specific effect of acupoints exists and whether this specific effect of acupoints is related to meridian and a collection of meridian Qi.Trials registrationClinical Trials.gov NCT00599586.

Project description:IntroductionDespite of recent advancement in the burns wound management, burn wound infection (BWI) is still one of the major cause of burns mortality. Patients who survive their burns injury still suffers from BWI related complication like delayed wound healing and poor scarring. BWI has been treated by application of topical antimicrobial agents or systemic antibiotics. Due to the global risk of developing systemic antibiotics resistance, medical research focuses on identifying single topical agent which has effective antimicrobial activity, easily available and cost effective. One such agent is acetic acid (AA). AA has been used as a topical antibacterial agent for the treatment of burns wounds for many years and has shown to have activity against gram-negative organisms including Pseudomonas aeruginosa. So far there has been no consensus on optimal concentration that has effective antimicrobial activity, frequency of application, duration of treatment and most importantly good patient's tolerability. A randomised control study is required to answer all these questions.ObjectiveTo investigate the efficacy and tolerability of 0.5% and 2% of AA when applied to colonised burns wounds for 3 days after admittance to the Queen Elizabeth Hospital Birmingham.Methods and analysisThis is a double-blinded, prospective, randomised, controlled, single-centre trial. Patients will be screened for eligibility in the inpatient area and those who are found to be eligible will be randomly assigned to one of two treatment groups: group 1: 0.5% AA (10 patients); group 2: 2% AA (10 patients); total number: 20 patients.Outcome measuresPrimary outcome: Efficacy will be assessed by measuring the bacterial load from microbiology wound swabs for three consecutive days.Secondary outcomes: (1) The assessment of antimicrobial activity of AA and the minimum inhibitory concentrations. (2) Patient's tolerance by assessing Visual Analogue Scale pain score. (3) Time to 95% wound healing of treatment area. (4) Patient's perceived treatment allocation.Ethics and disseminationAceticA trial protocol was approved by the National Research Ethics Service (West Midlands-Edgbaston Research Ethics Committee; 17/WM/0407; IRAS 234132). This article refers to protocol version 5.0 dated 6 July 2020. The analysed results will be presented at national and international conferences related to management of burn patients. The generated articles based on the trial results will be submitted to peer review journals for publication.Trial registration numberISRCTN11636684.

Project description:BackgroundChronic urticaria (CU) is a refractory skin disease with long duration and a high recurrence rate. Acupuncture has been widely used for the treatment of CU in clinical practice in China. However, until now, there has been no appropriately designed randomized controlled trial (RCT) to provide explicit evidence about the effectiveness of acupuncture for the treatment of CU worldwide. Therefore, we plan to conduct a pilot study to explore its effectiveness and safety and determine the feasibility of studying acupuncture in a future, full-scale, RCT of CU.Methods/designThis randomized, sham-controlled, participant-blinded and assessor-blinded pilot trial is underway in China. A total of 60 participants with CU will be randomly assigned to two groups in a 1:1 ratio: one treated with real acupuncture and the other with sham acupuncture, for 10?sessions over 2?weeks. The experimental group will receive acupuncture on a fixed prescription of acupoints, whereas the control group will receive sham acupuncture, namely minimal acupuncture on non-acupuncture points. The primary outcome will be the urticaria activity score (UAS). The secondary outcomes will include a visual analogue scale (VAS) score for itching intensity, the Dermatology Life Quality Index (DLQI), the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA), the humoral immunity index, serum total IgE, and adverse events. The UAS, VAS for itching and the DLQI will be conducted at baseline and at 1, 2, 3, and 4?weeks after randomization. The HAMD, HAMA, humoral immunity index, and serum total IgE will be assessed at baseline and at 2?weeks after randomization. Adverse events will be summarized at 1 week and 2 weeks after randomization.DiscussionThe pilot study mainly aims to investigate trial feasibility, and confirm basic information about its effects and safety. Results of this trial will help clarify whether the acupuncture treatment is beneficial for symptom improvement in patients with CU. The finding of this study will provide preliminary evidence on the effectiveness and safety of acupuncture for CU.Trial registrationAcupuncture-Moxibustion Clinical Trial Registry, AMCTR-ICR-18000190 .

Project description:ObjectiveThis study aims to provide evidence regarding the clinical efficacy of abdominal acupuncture for neck pain.MethodsThis randomized, patient and assessor-blind, sham-controlled trial was conducted at a Chinese medicine center in Hong Kong between November 2014 and March 2016. A total of 154 eligible participants (age range, 18-65 years) with neck pain were randomly assigned to receive abdominal (n = 77) or non-penetrating sham abdominal (sham group; n = 77) acupuncture. Each participant was administered treatment over six sessions by Registered Chinese Medicine Practitioners, in accordance with a standardized protocol. The primary outcome was mean improvement in neck pain disability scores evaluated by the Northwick Park Neck Pain Questionnaire (NPQ). Secondary outcomes included intensity of neck pain and health-related quality-of-life measures. The outcomes were assessed at baseline and at 2 and 6 weeks from baseline. Patients in the abdominal acupuncture group received additional follow-up evaluation at 14 weeks from baseline. Outcomes were evaluated by intention-to-treat analysis.ResultsAll participants provided informed consent for treatment and follow-up evaluation. Patients who received abdominal acupuncture exhibited greater improvement in NPQ scores than those who received sham treatment at both 2 and 6 weeks from baseline (intergroup mean differences, -5.75; 95% confidence interval [CI], -9.48 to -2.03; P = 0.008 and -8.65; 95% CI, -12.13 to -5.16; P < 0.001, respectively). The improvement in NPQ scores in the abdominal acupuncture group was even more significant at 14 weeks from baseline. Patients in the abdominal acupuncture group also exhibited significantly greater improvements in intensity of neck pain and a few quality-of-life measures than those in the sham abdominal acupuncture group, without any serious adverse events.ConclusionThese findings suggest that abdominal acupuncture is an effective alternative treatment for neck pain.Trial registrationChinese Clinical Trial Registry ChiCTR-TRC-14004932.
