Auricular acupuncture effectively reduces state anxiety before dental treatment-a randomised controlled trial
ABSTRACT OBJECTIVES: The objective of this study was to analyse whether auricular acupuncture, acupuncture at the outer ear, could reduce state anxiety before dental treatment. METHODS: This prospective, randomised patient-blinded study with 182 patients compared anxiety before dental treatment following auricular acupuncture at the relaxation-, tranquillizer- and master cerebral points (auricular acupuncture group) versus acupuncture at sham points (finger-, shoulder- and tonsil points; sham group) and a non-intervention control group. Anxiety was assessed using the Spielberger State Trait Anxiety Inventory (German version) before auricular acupuncture and 20 min thereafter, immediately before dental treatment. RESULTS: Auricular acupuncture reduced state anxiety score more effectively from 54.7 ± 10.8 to 46.9 ± 10.4 (mean ± SD) than sham acupuncture from 51.9 ± 10.2 to 48.4 ± 10.0. In contrast, state anxiety in the control group increased from 51.0 ± 11.7 to 54.0 ± 11.6 (mean increase +3.0; CI +4.7 to +1.2). The decrease in state anxiety in both intervention groups was statistically significant (p < 0.001) when compared to the non-intervention control group. After correcting for group differences in baseline state anxiety, the reduction in anxiety was -7.3 score points (CI -9.0 to -5.6) in the auricular acupuncture group and -3.7 score points (CI -5.4 to -1.9) in the sham group (p = 0.008). CONCLUSION: Auricular acupuncture, a minimally invasive method, effectively reduces state anxiety before dental treatment. CLINICAL RELEVANCE: Auricular acupuncture could be an option for patients scheduled for dental treatment, who experience an uncomfortable degree of anxiety and request an acute intervention for their anxiety.

ABSTRACT: The aim of this study was to systematically evaluate the literature on adverse events associated with auricular therapy (AT). Case reports, case series, surveys, and all types of clinical trials reporting adverse events of AT were included. Relevant articles were mainly retrieved from 13 electronic databases and seven Chinese journals on complementary medicine. AT-related adverse events were reported in 32 randomized controlled trials, five uncontrolled clinical trials, four case reports, and two controlled clinical trials. For auricular acupuncture, the most frequently reported adverse events were tenderness or pain at insertion, dizziness, local discomfort, minor bleeding and nausea, and so forth. For auricular acupressure, local skin irritation and discomfort, mild tenderness or pain, and dizziness were commonly reported. Skin irritation, local discomfort, and pain were detected in auricular electroacupuncture, and minor infection was identified in auricular bloodletting therapy. Most of these events were transient, mild, and tolerable, and no serious adverse events were identified. Our findings provide preliminary evidence that AT is a relatively safe approach. Considering the patient’s safety, prospective or retrospective surveys are needed in future research to gather practitioner-reported and patient-reported adverse events on AT, and the quality of adverse events reporting in future AT trials should be improved.Evidence-based Complementary and Alternative Medicine 11/2014; 2014(Article ID 506758):20 Pages.

ABSTRACT: Background: Perennial allergic rhinitis (PAR) has a high and increasing prevalence worldwide. Ear acupressure (EAP) is a noninvasive semi‐self-administered form of acupuncture. Previous studies indicated that EAP could be effective and safe for AR symptom management. However, there was insufficient evidence to confirm this. This study investigated whether EAP, a noninvasive clinical alternative to acupuncture, is effective and safe for PAR. Methods: This is an international, multicenter, randomized, single-blind, sham-controlled trial. The trial was conducted at two centers: Royal Melbourne Institute of Technology University (Melbourne, Australia) Clinical Trial Clinic and Guangdong Provincial Hospital of Chinese Medicine, Guangzhou, China. PAR participants were randomized to receive real or sham EAP treatment once a week for 8 weeks and then were followed-up for 12 weeks. Participants were instructed to administer EAP stimulation three times daily. Symptom severity and quality of life (QoL) were evaluated. Adverse events (AEs) were also monitored. Intention-to-treat analysis on change of symptom scores and QoL was applied. Results: Two hundred forty-five participants were randomly assigned to real (n = 124) and sham EAP (n = 121) groups. Twenty-five participants discontinued during treatment and 15 participants dropped out during follow-up. At the end of treatment and follow-up periods, changes of global QoL score were significantly greater in the real EAP group compared with the sham group. At the end of follow-up, scores for total nasal symptom, runny nose, and eye symptoms in the real EAP group had a greater reduction compared with the sham group. Overall, both real and sham EAP were well tolerated. Two severe AEs were reported but were not considered related to the EAP procedures. Conclusion: In conclusion, EAP showed short-term and extended benefit for improving PAR symptoms and QoL for PAR patients.American journal of rhinology & allergy 08/2014; 28(4).

ABSTRACT: Background. Acupuncture has been shown to reduce preoperative anxiety in several previous randomized controlled trials (RCTs). In order to assess the preoperative anxiolytic efficacy of acupuncture therapy, this study conducted a meta-analysis of an array of appropriate studies. Methods. Four electronic databases (MEDLINE, EMBASE, CENTRAL, and CINAHL) were searched up to February 2014. In the meta-analysis data were included from RCT studies in which groups receiving preoperative acupuncture treatment were compared with control groups receiving a placebo for anxiety. Results. Fourteen publications (N = 1,034) were included. Six publications, using the State-Trait Anxiety Inventory-State (STAI-S), reported that acupuncture interventions led to greater reductions in preoperative anxiety relative to sham acupuncture (mean difference = 5.63, P < .00001, 95% CI [4.14, 7.11]). Further eight publications, employing visual analogue scales (VAS), also indicated significant differences in preoperative anxiety amelioration between acupuncture and sham acupuncture (mean difference = 19.23, P < .00001, 95% CI [16.34, 22.12]). Conclusions. Acupuncture therapy aiming at reducing preoperative anxiety has a statistically significant effect relative to placebo or nontreatment conditions. Well-designed and rigorous studies that employ large sample sizes are necessary to corroborate this finding.Evidence-based Complementary and Alternative Medicine 09/2014; 2014:850367.
