Auricular acupuncture effectively reduces state anxiety before dental treatment—a randomised controlled trial

Interventions to reduce adult state anxiety, dental trait anxiety, and dental phobia: A systematic review and meta-analyses of randomized controlled trials

This review evaluates randomized controlled trials (RCTs) intervening on adult state anxiety (fear and emotional distress during dental treatment), chronic dental (trait) anxiety or dental phobia (disproportionately high trait anxiety; meeting diagnostic criteria for specific phobia). Seven online databases were systematically searched. 173 RCTs met inclusion criteria, of which 67 qualified for 14 pooled analyses. To alleviate state anxiety during oral surgery, moderate-certainty evidence supports employing hypnosis (SMD=-0.31, 95 %CI[-0.56,-0.05]), and low-certainty evidence supports prescribing benzodiazepines (SMD=-0.43, [-0.74,-0.12]). Evidence for reducing state anxiety is inconclusive regarding psychotherapy, and does not support virtual reality exposure therapy (VRET), virtual reality distraction, music, aromatherapy, video information and acupuncture. To reduce trait anxiety, moderate-certainty evidence supports using Cognitive Behavioral Therapy (CBT; SMD=-0.65, [-1.06, -0.24]). Regarding dental phobia, evidence with low-to-moderate certainty supports employing psychotherapy (SMD=-0.48, [-0.72,-0.24]), and CBT specifically (SMD=-0.43, [-0.68,-0.17]), but not VRET. These results show that dental anxieties are manageable and treatable. Clinicians should ensure that interventions match their purpose-managing acute emotions during treatment, or alleviating chronic anxiety and avoidance tendencies. Existing research gaps underscore the necessity for future trials to minimize bias and follow CONSORT reporting guidelines.

Ear-Marking Relief: A Meta-Analysis on the Efficacy of Auricular Acupressure in Alleviating Anxiety Disorders

BACKGROUND

The increasing worldwide mental health crisis, notably anxiety, emphasizes the urgency for available and effective interventions. Traditional therapies, although beneficial, pose limitations due to their considerable costs and possible adverse effects, thereby inviting alternative treatments such as auricular acupressure (AA). This non-pharmacological, integrative method, underpinned by Eastern and Western medical principles, presents a significant prospect for managing anxiety.

OBJECTIVE

This study aims to evaluate the existing evidence on the efficacy of AA in reducing anxiety, as elucidated through a systematic review.

METHODS

A comprehensive search of randomized controlled trials was conducted across various databases: the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wan Fang, and Database for Chinese Technical Periodicals (VIP). Two reviewers retrieved the pertinent studies and assessed their methodological quality. A meta-analysis was then conducted, incorporating data from all relevant time points.

RESULTS

Upon examining 25 studies encompassing 1,909 participants, it was discerned that AA significantly diminished anxiety (SMD = -1.1074; 95% confidence interval, -1.348 to -0.801; z = 7.70, p < 0.01). Subgroup analyses indicated that neither an increased number of auricular points nor extended intervention augmented effects. Larger effect sizes were associated with probing and avoidance of sham acupressure. Notably, 23 of the 25 studies exhibited some bias, suggesting further research is necessary.

CONCLUSIONS

The extant evidence advocates for AA as an effective supplementary intervention that reduces patient anxiety. The results hint at a potential placebo effect elicited by sham acupressure, necessitating rigorous control group definitions in future inquiries. The study findings suggest that fewer acupressure points and shorter intervention durations could effectively alleviate anxiety symptoms. Nonetheless, the significant heterogeneity across the studies underscores the requirement for more stringent research methodologies to substantiate these conclusions.

Hintergrund

Die weltweit zunehmende Krise der psychischen Gesundheit, vor allem von Angstzuständen, zeigt, dass dringend verfügbare und wirksame Interventionen erforderlich sind. Herkömmliche Therapien sind zwar hilfreich, werden aber durch ihre hohen Kosten und möglichen unerwünschten Wirkungen eingeschränkt, so dass alternative Behandlungen wie die Ohrakupressur gefragt sind. Diese nicht-pharmakologische, integrative Methode, die sich auf östliche und westliche medizinische Prinzipien stützt, stellt eine bedeutsame Perspektive für die Behandlung von Angstzuständen dar.

Ziel

Ziel dieser Studie ist es, die vorhandenen Evidenzen für die Wirksamkeit der Ohrakupressur (auricular acupressure, AA) zur Verringerung von Angstzuständen, die in einer systematischen Übersichtsarbeit ermittelt wurden, zu bewerten.

Methoden

Es wurde eine umfassende Suche nach randomisierten kontrollierten Studien in verschiedenen Datenbanken durchgeführt: Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wan Fang und Database for Chinese Technical Periodicals (VIP). Zwei Gutachter suchten die einschlägigen Studien heraus und bewerteten ihre methodische Qualität. Anschliessend erfolgte eine Metaanalyse, bei der Daten aller relevanten Zeitpunkte berücksichtigt wurden.

Ergebnisse:

Die Untersuchung von 25 Studien mit 1’909 Teilnehmern ergab, dass die Ohrakupressur (AA) Angstzustände signifikant verringerte (SMD = −1,1074; 95%-KI: −1,348 bis −0,801; z = 7,70, p < 0,01). Subgruppenanalysen zeigten, dass die Effekte weder durch eine höhere Anzahl von Ohrpunkten noch durch eine längere Intervention verstärkt wurden. Grössere Effektstärken waren mit Sondenverwendung und Vermeidung von Scheinakupressur assoziiert. Hervorzuheben ist, dass 23 der 25 Studien eine gewisse Verzerrung aufwiesen, weshalb weitere Untersuchungen erforderlich sind.

Schlussfolgerungen

Die vorhandene Evidenzlage stützt die Ohrakupressur (AA) als wirksame unterstützende Intervention, die die Angst der Patienten verringert. Die Ergebnisse deuten auf einen potenziellen Placeboeffekt durch Scheinakupressur hin, so dass in künftigen Untersuchungen strenge Kontrollgruppendefinitionen erforderlich sind. Die Studienergebnisse sprechen dafür, dass eine geringere Anzahl von Akupressurpunkten und kürzere Interventionszeiten die Angstsymptome wirksam lindern können. Die starke Heterogenität der Studien zeigt allerdings, dass strengere wissenschaftliche Methoden erforderlich sind, um diese Schlussfolgerungen zu untermauern.

Acupuncture for Management of Endodontic Emergencies: a Review

Root canal treatment (RCT) employed for painful endodontic conditions like apical periodontitis and irreversible pulpitis is associated with a high incidence of postoperative pain. Pharmacological management for this purpose is effective, but not entirely free from side effects and in some cases may fail to provide adequate relief. Furthermore, concerns have been raised regarding the transmission of coronavirus disease-2019 (COVID-19) as a result of the aerosols generated and prolonged chair side time required for RCT. Acupuncture is a traditional Chinese therapy commonly employed as an alternative for the treatment of pain. And what's more, the use of acupuncture has been recently reported as treatment for the management of endodontic pain as well as on the anesthetic success in patients with irreversible pulpitis. This review aims to evaluate the current evidence for acupuncture in endodontics and its potential role in emergency pain relief and management for patients. To combat this, a thorough search for literature within the field was performed in five electronic databases. Retrieved studies were screened according to the pre-defined eligibility criteria. After both an electronic and manual search, five studies were selected for review. These studies reported the beneficial effects of acupuncture in reducing the failure of nerve block in patients with irreversible pulpitis and in controlling both intraoperative and postoperative pain following RCT. In addition, it was also reported to reduce anxiety surrounding the dental procedure and minimized the intake of analgesics after the endodontic procedure, which can result in some unwanted side effects. However, more in depth clinical research is required before any recommendation regarding the application of acupuncture in endodontic patients can be made.

Effectiveness of low-level laser therapy in reducing pain perception of children during dental local anesthetic administration using laser acupuncture pen on the LI4 point: a randomized clinical trial

PURPOSE

Laser acupuncture, a non-invasive variant of acupuncture, has been proven effective in the medical and dental fields. Hence, the present study aims to determine the effect of low-level laser therapy on the LI4 point, using a laser acupuncture pen, in reducing children's pain during local anesthetic (LA) administration.

METHODS

Children in the age range of 8-12 years, in need of LA administration, were randomly assigned to two groups: Group I: laser acupuncture, Group II: control. For all the children, baseline simplified Modified Child Dental Anxiety Scale-Faces version (MCDAS_(f)) was recorded, followed by laser acupuncture or standard care. Following the conventional protocol, LA was administered. The procedural pain was assessed using the Faces, Legs, Activity, Cry and Consolability scale (FLACC) and Faces Pain Scale-Revised (FPS-R). All the variations in pulse rate were recorded from baseline to the completion of LA administration. After the procedure, simplified MCDAS_(f) was recorded one more time. The data were tabulated and analyzed statistically.

RESULTS

A significant reduction in anxiety after LA administration, as observed in MCDAS_(f) score, was noticed only in the laser acupuncture group. The pain scores, as reported in FPS-R, were low in children randomized to the laser group compared to the control. The FLACC pain scores also showed low values in the experimental group.

CONCLUSION

Based on the study findings, within the limitations, low-level laser therapy using a laser acupuncture pen can reduce the pain perception of children undergoing LA administration and alleviate dental anxiety.

Management of fear and anxiety in dental treatments: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVES

This systematic review was to compare the effects of interventions for the management of fear and anxiety for dental treatments.

METHODS

This research project was applied to PubMed, CENTRAL, Web of Science, Cochrane library databases. The last search was run on March 31st, 2021. A list of references of relevant articles and previous reviews were checked. Qualitative and quantitative analyses were performed.

RESULTS

A total of 20 eligible randomized controlled trials were included, and 969 participations in experimental group and 892 participations in the control group were involved. Anxiety levels decreased more in intervention groups than in control groups (Z = 3.47, P = 0.0005, SMD = - 0.62, 95% CI - 0.98 to - 0.27). For adults, there was statistical difference between experimental and control groups [Z = 2.14, P = 0.03, 95% CI - 0.54 (- 1.03, - 0.04)], while there was not no such statistical difference in children and adolescents [Z = 1.62, P = 0.11, 95% CI - 0.60 (- 1.32, 0.13)]. Patients experienced a significant decrease in anxiety level using sedation drugs [Z = 2.44, P = 0.01, 95% CI - 0.61 (- 1.10, - 0.12)] and audio-visual distractions [Z = 3.1, P = 0.002, 95% CI - 0.86 (- 1.40, - 0.32)]. For the informative intervention groups, patients did not show significant difference than control groups [Z = 1.22, P = 0.22, 95% CI - 0.55 (- 1.43, 0. 33)]. There was no statistical difference in vital signs [Z = 1.39, P = 0.16, 95% CI - 0.25 (- 0.61, 0.10)] and pain levels [Z = 0.69, P = 0.49; SMD = - 0.06, 95% CI (0.27, 0.11)] between intervention and control groups.

CONCLUSIONS

Interventions should be used in managing anxiety and fear for dental treatment. It might be effective for anxiety alleviating for adults, but there was a low certainty of evidence that interventions could reduce anxiety level in children and adolescents. Sedation drugs and audio-visual distractions might be useful for managing dental fear and anxiety. Pain levels and vital signs could not be improved form our study. High-quality randomized clinical trials are required for further study.

Effects of electroacupuncture on perioperative anxiety and stress response in patients undergoing surgery for gastric or colorectal cancer: Study protocol for a randomized controlled trial

BACKGROUND

Perioperative anxiety is one of the main psychological stresses experienced by patients who undergo cancer surgery. The surgery itself inevitably causes a stress response characterized by activation of the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. Both the perioperative anxiety and surgical stress response lead to increased levels of catecholamines and prostaglandins, which may be related to perioperative suppression of antimetastatic immunity and tumor-promoting alterations in the microenvironment. Hence, we designed this clinical trial to investigate the effect of electroacupuncture in reducing perioperative anxiety and surgical stress response.

METHODS

This is a randomized, single-center, parallel, and controlled clinical trial. Seventy-eight participants between the ages of 35 and 85 with gastric or colorectal cancer who plan to undergo tumorectomy will be randomly divided into an electroacupuncture group and a control group. The primary outcome will be the six-item short form of the State-Trait Anxiety Inventory score. The secondary outcomes will be the Amsterdam Preoperative Anxiety and Information Scale score; levels of plasma cortisol, adrenocorticotropic hormone, interleukin-6, and tumor necrosis factor-α; first exhaust time after surgery; postoperative quality of the recovery-15 score, numeric rating scale for pain score; and dosage of postoperative analgesics.

DISCUSSION

Cumulative studies revealed the efficacy of various types of acupuncture therapy with regard to reducing the anxiety and stress response caused by surgery. We expect that the results of this trial will provide high-quality clinical evidence for the choice of perioperative acupuncture for patients undergoing cancer surgery.

The Effect of Auriculotherapy on Situational Anxiety Trigged by Examinations: A Randomized Pilot Trial

Background: Auriculotherapy may activate the parasympathetic nerve system and reduce anxiety levels. Short-term auriculotherapy’s effects and safety on university students’ anxiety levels was assessed prior to exams. Methods: A randomized, controlled pilot trial was conducted. The day before the exam, university students were randomly allocated to the auriculotherapy group (AA, n = 13) or the waiting-list group (WG, n = 13). Baseline measures were taken 4 weeks before the exam at Time point (TP 0); at 7.30 a.m. on the day before the exam (TP I); at 11 a.m. before auriculotherapy (TP II); 30 min after AA (TP III); and at 7.30 a.m. before the exam (TP IV). The outcomes were the State-Trait-Anxiety Inventory (STAI); quality of night-sleep, Visual Analogue scale (VAS) for anxiety, and salivary cortisol. Adverse events were also recorded. Results: A total of 26 students participated in this study and became more anxious as assessed by STAI in TPII (p = 0.002) and TPIV (p = 0.000) than TP0. AA reduced the STAI in TPIII (p = 0.045) and PIV (p = 0.001) and the VAS (p = 0.012) in TPIV. Cortisol was reduced in TPIII (p = 0.004), and the AA slept better (p = 0.014) at TPIV. Discomfort at the auricular site was reported in only one AA participant. Conclusions: Auriculotherapy appeared safe and effective in reducing anxiety levels before university exams.

Auricular Acupuncture for Preoperative Anxiety in Parturient Women with Scheduled Cesarean Section: A Randomized Placebo-Controlled Blind Study

Introduction: Preoperative anxiety before cesarean section is a major issue. Nonpharmacologic anxiety control is believed to be more suitable in pregnant women. Auricular acupuncture (AA) is an inexpensive, easy-to-use, and validated intervention to reduce anxiety in different surgical settings. We evaluated the effect of AA on preoperative cesarean section anxiety. Methods: In a prospective, blind, controlled trial, pregnant women with a scheduled cesarean section under spinal anesthesia were randomized to receive AA with needle, AA without needle (sham), or usual care (no intervention). Anxiety level was assessed by using a visual analogue scale for anxiety (VAS-A; 0-minimal anxiety, 100-maximal anxiety) at three time points: inclusion (pre-induction room-T0), when entering the operating room (T1), and before incision (T2). The primary outcome was the VAS-A variation (percentage changes) between T0 and T1 in the AAe group compared with that in the sham AA group. The secondary outcomes were the VAS-A variation between T0 and T1 in the AA group compared with that in the control group, and the variation between T0 and T2 compared between the three groups, the effect of AA on parasympathetic tone, and the incidence of adverse effects. Results: In women immediately before anesthesia for cesarean section, the AA produced a 19% decrease of anxiety, compared with a 21% anxiety increase in sham AA, which is significantly different. The effect of AA was more present in women with low initial anxiety. The proportion of patients reaching clinically significant anxiety reduction (>33% from the initial level) was 2.5 times higher in the AA group (p = 0.02) compared with the sham group. No differences in anxiety variations were found compared with the no-intervention group. No effect of AA was noted on parasympathetic tone. Conclusion: Compared with sham, AA decreased maternal anxiety level when arriving in the operation room and just before the beginning of the cesarean section, with a trend toward improvement compared with usual care.

Auricular Acupuncture During Chemotherapy Infusion in Breast Cancer Patients: A Feasibility Study

Introduction: Breast cancer patients undergoing chemotherapy experience multiple distressing symptoms. The authors investigated the feasibility and potential benefits of auricular acupuncture during chemotherapy infusion in this population. Materials and Methods: Women with stage I-III breast cancer undergoing chemotherapy were enrolled and followed for three chemotherapy cycles. During the first cycle of chemotherapy that participants received after study enrollment, they were provided with educational materials. During the second and third cycles of chemotherapy after enrollment, they received auricular acupuncture. The primary outcome was feasibility, assessed by recruitment, retention, and completion of assessments. Secondary outcomes included symptom burden (Edmonton Symptom Assessment System-Revised Version) and anxiety (State-Trait Anxiety Inventory-State), assessed at four timepoints for each cycle: day 1, pre-education/acupuncture (T1); day 1, post-education/acupuncture (T2); day 2 (T3); and day 5 (T4). Nausea and vomiting (Multinational Association of Supportive Care in Cancer [MASCC] Antiemesis Tool) were assessed on days 2 and 5. Paired t test was used to compare patient-reported outcomes during cycle 1 (education) versus an average of outcomes during cycles 2 and 3 (acupuncture). Results: Twenty-six patients were enrolled, of which 24 completed all acupuncture sessions and 22 completed all outcome assessments. In cycles 2 and 3 versus cycle 1, participants experienced significant reductions in symptom burden (change from T1 to T4: -7.9 ± 13.6, p = 0.02), anxiety (change from T1 to T2: -3.3 ± 6.5, p = 0.02), and nausea severity on day 2 (-1.3 ± 2.6, p = 0.04). Conclusions: The delivery of auricular acupuncture during chemotherapy infusion was feasible and associated with reduction of symptom burden, anxiety, and nausea in breast cancer patients. Larger-scale clinical studies are needed to confirm these findings. Clinical Trial Registration number: NCT03170648.

The effect of preoperative patient-reported anxiety on morbidity and mortality outcomes in patients undergoing major general surgery

Excessive levels of anxiety may negatively influence treatment outcomes and likely increase patient suffering. We designed a prospective observational study to assess whether preoperative patient-reported anxiety affects major general surgery outcomes. We prospectively administered the State-Trait Anxiety Inventory (STAI) to measure preoperative anxiety in patients awaiting major general surgical procedures. Patients were grouped by STAI scores according to established cutoffs: no anxiety (STAI < 40) and anxiety (STAI ≥ 40). Four hundred patients completed the questionnaires and underwent surgery, with an average interval from questionnaire completion to surgery of 4 days. Applying a state anxiety (STAI-S) score ≥ 40 as a reference point, the prevalence of patient-reported anxiety was 60.5% (241 of 400). The mean STAI-S score for these patients was 50.48 ± 7.77. The mean age of the entire cohort was 58.5 ± 14.12 years. The majority of participants were male (53.8%). The distribution of sex by anxiety status showed that 53.5% of women and 46.5% of men had anxiety (p = 0.003). In the entire cohort, postoperative complications occurred in 23.9% and 28.6% of the no anxiety and anxiety groups, respectively. The difference was nonsignificant. In a subgroup of patients who underwent high-risk complex procedures (N = 221), however, postoperative complications occurred in 31.4% and 45.2% of the no anxiety and anxiety groups, respectively. This difference was significant at p = 0.004. Of the patients who were anxious, 3.3% (8 of 241) died during hospitalization following surgery, compared with 4.4% of the patients (7 of 159) who were not anxious (p = 0.577). In the multivariable analysis adjusted for covariates and based on the results of subgroup analysis, preoperative anxiety assessed by the STAIS score was associated with morbidity (OR 2.12, CI 1.14–3.96; p = 0.018) but not mortality. The majority of enrolled patients in this study were classified as having high- to very high-level preoperative clinical anxiety, and we found a significant quantitative effect of patient-reported anxiety on morbidity but not mortality after surgery.

Auriculotherapy used to manage orthodontic pain: a randomized controlled pilot study

INTRODUCTION

Several methods are commonly used to decrease orthodontic pain, but versatile tools and standardized protocols are still lacking.

OBJECTIVE

In response to the need for alternatives to conventional analgesic methods, this study evaluates the analgesic effects of auriculotherapy (AT) during the first three months of fixed orthodontic treatment.

METHODS

A sample of 36 subjects was selected, with patients randomly allocated into two homogeneous groups, Study Group (SG) and Control Group (CG), depending on the application/non-application of AT. Patients rated their pain scores monthly from 0 to 10, on visual analogue scales (VAS) at the time of bonding (T0) and again at two appliance adjustments (T1 and T2). At each of these treatment phases, VAS was applied in six different time moments (TM): immediately before, immediately after, after 4 hours, after 8 hours, after 24 hours, and after 72h hours. Descriptive statistical analysis, a Student's t-test, and a Chi-square test were applied to the collected data (statistical significance for p< 0.05).

RESULTS

SG patients reported lower pain levels than CG patients, both at T0, T1 and T2. Moreover, average pain intensity values were lower in the SG for all TM analyzed, with the t-test significant (p< 0.05) for most TMs.

CONCLUSION

AT was effective in the pain treatment of patients with fixed orthodontic appliances. Further studies are needed with a sham control group to confirm the validity of these results.

Auricular stimulation for preoperative anxiety - A systematic review and meta-analysis of randomized controlled clinical trials

STUDY OBJECTIVE

Previous randomized controlled trials (RCTs) suggest that auricular stimulation (AS) is safe and effective in treatment of preoperative anxiety; however, a systematic evaluation is lacking. The aim was to summarize the evidence on efficacy and safety of AS for preoperative anxiety, as well as for other outcomes.

DESIGN

We conducted a systematic review of RCTs including patients from all available populations. The search was done through MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science and Scopus Database from inception to June 2020. Study selection and data extraction were performed in by 2 independent reviewers with ability to resolve disagreements by a third author. Meta-analyses as well as the risk of bias and evidence quality assessments were performed according to the Cochrane 6.2, 2021 handbook recommendations.

INTERVENTIONS

We compared AS with pharmacological and non-pharmacological interventions for different outcomes.

MEASUREMENTS

We assessed the repercussion of the evaluated interventions over anxiety scores and their safety, physiological parameters, perioperative medications requirement and intensity of postoperative pain.

MAIN RESULTS

We have included 15 studies with 1603 patients. AS has presented reduced anxiety scores as compared to the sham control (Standardized Mean Difference (SMD) -0.72, 95% confidence interval (CI) -1.09 to -0.36, p < 0.0001; 8 trials; 701 patients; heterogeneity: I² 80%; GRADE: moderate certainty) and to no intervention (SMD -1.01, 95% CI -1.58 to -0.45, p = 0.0004; 4 trials; 420 patients; heterogeneity: I² 84%; GRADE: very low certainty). There was no difference between AS and benzodiazepines (SMD -0.03; 95% CI: -0.34 to 0.28; p = 0.84; 3 trials; 158 patients; heterogeneity: I² 0%; GRADE: very low certainty). No trials reported serious adverse effects of AS.

CONCLUSIONS

AS may be useful in treatment of preoperative anxiety. Due to heterogenous certainty in effect estimates, further research is needed to clarify the actual efficacy of AS for preoperative anxiety.

Dealing with Anxious Patients: An Integrative Review of the Literature on Nonpharmaceutical Interventions to Reduce Anxiety in Patients Undergoing Medical or Dental Procedures

Objectives: A previous systematic literature review (SLR) evaluated 501 experiments on reducing patient anxiety across medical and dental environments. This integrative review examines those interventions and explores possible mechanisms leading to relative success or failure within those environments, in the interest of interprofessional education and communication. Methods: Reviewers evaluated 501 experiments testing interventions for reducing patient anxiety in a variety of medical and dental health care settings. Methodology for the SLR, largely following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, is briefly reviewed. Results: A total of 501 experiments (from 408 articles) met review criteria. One hundred and forty-three Music experiments were included, and Music interventions were largely effective, except in the case of colonoscopy. Education is the only intervention that occasionally (5 times of 130 experiments) raised patient anxiety in the face of a procedure; the discussion focuses on the wisdom of assessing patient need for information. Thirty-seven Cognitive Behavioral Therapy (CBT) experiments of various types are included, with a success rate of 89%, with a particularly high rate of success (12 of 12 experiments) in dentistry. Massage has a success rate that is similar to that of CBT, but Massage has been tested in far fewer specialty areas. Relaxation has been tested in every specialty area, except mechanical ventilation, with promising results. Acupuncture and Acupressure have not been widely tested, but their effectiveness rate is 100% when it comes to reducing patient anxiety in various procedural settings. Similarly, experiments show Hypnosis to be successful in 90% of trials. In contrast, Distraction was successful in only 40% of the experiments summarized, although it was more effective in dentistry. A variety of Nature-based Interventions (Aromatherapy, Nature Sounds, and Visual Stimuli) were highly successful across a variety of settings. Discussion: Possible mechanisms are discussed, along with commentary on feasibility. Limitations include publication bias, small sample sizes, and the lack of placebo controls. Future areas of research are pointed out.

Effects of photobiomodulation on auriculotherapy points for sleep disorders, anxiety, and temporomandibular dysfunctions

Objective: The purpose of this study was to evaluatephotobiomodulation applied at auriculotherapy points forsleep disorder (SD) and anxiety related to temporomandibulardysfunction (TMD).Methods: The study consisted of two groups of 20 participants: Auriculotherapy group (A) and Control Group(C). The participants responded to the RDC/TMD, Fletcher & Luckett questionnaires, and the Beck Anxiety Inventory to analyze TMD, SD, and anxiety before and after the treatment.Results: The participants presented scores corresponding to mild to moderateanxiety (MDN = 17; CI = [13.16;22.31]) and after treatment, normalor non-existent anxiety (MDN = 9; CI = [8.76; 17.12]) (p = 0.005). There was no significant difference (p > 0.05) between the controland 20 auriculotherapy groups for TMD and SD.Discussion: The results suggest that auriculotherapy was effective in the treatment of anxiety. However, it did not prove effective with the results of the SD and symptoms of TMD.

Auricular Acupuncture for Preoperative Anxiety-Protocol of Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background: Preoperative anxiety causes profound psychological and physiological reactions that may lead to a worse postoperative recovery, higher intensity of acute and persistent postsurgical pain and impaired quality of life in the postoperative period. Previous randomized controlled trials (RCTs) suggest that auricular acupuncture (AA) is safe and effective in the treatment of preoperative anxiety; however there is a lack of systematic evidence on this topic. Therefore, this protocol was developed following the PRISMA guidelines to adequately evaluate the existing literature regarding the value of AA for the reduction in anxiety in patients in a preoperative setting, compared to other forms of acupuncture, pharmacological, or no control interventions and measured with questionnaires regarding anxiety and fear. Methods: The following databases will be searched: MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, and Scopus Database. RCTs will be included if an abstract is available in English. Data collection and analysis will be conducted by two reviewers independently. Quality and risk assessment of included studies will be done using the Cochrane 5.1.0 handbook criteria and meta-analysis of effectiveness and symptom scores will be conducted using the statistical software RevMan V.5.3. Conclusions: This systematic review will evaluate the efficacy and safety of AA for preoperative anxiety. Since all data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. The results may be published in a peer-reviewed journal or be presented in relevant conferences. Registration number: PROSPERO ID CRD42020.

Dental students' knowledge of and attitudes towards complementary and alternative medicine in Australia - An exploratory study

OBJECTIVES

While complementary and alternative medicine (CAM) is used by more than half of Australians, its role in dentistry is rarely covered in the curricula of Australian dental schools. This study aimed to investigate dental students' knowledge of and attitudes towards CAM.

DESIGN

Australian dental students in the final two years of their study were invited to undertake a survey. These questions consisted of five clinically relevant case vignettes, for which there was only one correct answer amongst four possible options and seven self-reported perspective-based questions. Results were analysed using descriptive statistics.

RESULTS

Of the 185 students that participated, the mean correct response rate for the five clinical scenarios was 3.46 ± 0.95 (range: 0-5 out of 5). Of 185 students, 157 (85 %) answered more than half of the questions correctly. All five questions were answered correctly by 19 (10 %) students. Most (74 %) students self-reported to have little to no knowledge. More than two-thirds of dental students reported an interest in and belief in the effectiveness of CAM. A similar proportion expressed a desire for the integration of CAM content into their undergraduate curriculum.

CONCLUSIONS

Despite approximately three out of four of dental students in this study having little to no knowledge on CAM, attitudes towards CAM therapies, and the need to integrate them into the dental curriculum, were generally positive. Future research into identifying specific knowledge gaps could help to redesign improved dental curricula.

Herbal medicines as anxiolytics prior to third molar surgical extraction. A randomized controlled clinical trial

OBJECTIVES

This study aimed to compare the effects of Passiflora incarnata, Erythrina mulungu, and midazolam in controlling anxiety in patients undergoing mandibular third molar extraction.

METHODS

The volunteers underwent extraction of their third mandibular molars in a randomized, placebo-controlled, triple-blind, and parallel clinical trial. Passiflora incarnata (500 mg), Erythrina mulungu (500 mg), or midazolam (15 mg) was orally administered 60 min before the surgery. The anxiety level of participants was evaluated using questionnaires and measurements of physical parameters, including heart rate (HR), blood pressure (BP), and oxygen saturation (SpO₂).

RESULTS

A total of 200 volunteers were included in this clinical trial. Considering each procedure independently, no significant differences (p > 0.05) in BP, HR, and SpO₂ were observed among the protocols.

CONCLUSIONS

Passiflora incarnata showed a similar effect to midazolam but differed from placebo and mulungu, which were unable to control anxiety in this situation. Therefore, the results suggest that Passiflora configures an herbal medicine with an anxiolytic effect, adequate to use in third molar extractions.

CLINICAL RELEVANCE

The use of Passiflora incarnata may be an alternative to benzodiazepines for controlling anxiety in patients scheduled for oral surgery under local anesthesia.

Auricular stimulation vs. expressive writing for exam anxiety in medical students - A randomized crossover investigation

OBJECTIVE

Auricular stimulation (AS) is a promising method in the treatment of situational anxiety. Expressive writing (EW) is an established psychological method, which reduces test anxiety and improves exam results. The aim of this crossover trial was to compare AS with EW, and with the no intervention (NI) condition, for treatment of exam anxiety.

METHODS

Healthy medical students underwent 3 comparable anatomy exams with an interval of one month, either performing EW, receiving AS or NI prior to the exam; the order of interventions was randomized. AS was applied using indwelling fixed needles bilaterally at the areas innervated mostly by the auricular branch of the vagal nerve on the day before the exam. Anxiety level, measured using State-Trait-Anxiety Inventory (STAI) before and after the interventions and immediately before exam, was the primary outcome. Quality of night sleep, blood pressure, heart rate and activity of salivary alpha-amylase (sAA) were analyzed across 3 conditions.

RESULTS

All 37 included participants completed the study. Anxiety level (STAI) decreased immediately after AS in comparison with baseline (P = 0.02) and remained lower in comparison with that after EW and NI (P<0.01) on the day of exam. After EW and NI anxiety increased on the day of exam in comparison with baseline (P<0.01). Quality of sleep improved after AS in comparison with both control conditions (P<0.01). The activity of sAA decreased after EW and after AS (P<0.05) but not after NI condition.

CONCLUSION

Auricular stimulation, but not expressive writing, reduced exam anxiety and improved quality of sleep in medical students. These changes might be due to reduced activity of the sympathetic nervous system.

Interventions for increasing acceptance of local anaesthetic in children and adolescents having dental treatment

BACKGROUND

Delivery of pain-free dentistry is crucial for reducing fear and anxiety, completion of treatment, and increasing acceptance of future dental treatment in children. Local anaesthetic (LA) facilitates this pain-free approach but it remains challenging. A number of interventions to help children cope with delivery of LA have been described, with no consensus on the best method to increase its acceptance.

OBJECTIVES

To evaluate the effects of methods for acceptance of LA in children and adolescents during dental treatment.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the Cochrane Oral Health's Trials Register (to 24 May 2019); the Cochrane Central Register of Controlled Trials (CENTRAL; 2019 Issue 4) in the Cochrane Library (searched 24 May 2019); MEDLINE Ovid (1946 to 24 of May 2019); Embase Ovid (1980 to 24 May 2019); and Web of Science (1900 to 24 May 2019). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and World Health Organization International Clinical Trials Registry Platform were also searched to 24 May 2019. There were no restrictions on language or date of publications.

SELECTION CRITERIA

Parallel randomised controlled trials (RCTs) of interventions used to increase acceptance of dental LA in children and adolescents under the age of 18 years.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We performed data extraction and assessment of risk of bias independently and in duplicate. We contacted authors for missing information. We assessed the certainty of the body of evidence using GRADE.

MAIN RESULTS

We included 26 trials with 2435 randomised participants aged between 2 and 16 years. Studies were carried out between 2002 and 2019 in dental clinics in the UK, USA, the Netherlands, Iran, India, France, Egypt, Saudi Arabia, Syria, Mexico, and Korea. Studies included equipment interventions (using several LA delivery devices for injection or audiovisual aids used immediately prior to or during LA delivery or both) and dentist interventions (psychological behaviour interventions delivered in advance of LA (video modelling), or immediately prior to or during delivery of LA or both (hypnosis, counter-stimulation). We judged one study to be at low risk and the rest at high risk of bias. Clinical heterogeneity of the included studies rendered it impossible to pool data into meta-analyses. None of the studies reported on our primary outcome of acceptance of LA. No studies reported on the following secondary outcomes: completion of dental treatment, successful LA/painless treatment, patient satisfaction, parent satisfaction, and adverse events. Audiovisual distraction compared to conventional treatment: the evidence was uncertain for the outcome pain-related behaviour during delivery of LA with a reduction in negative behaviour when 3D video glasses where used in the audiovisual distraction group (risk ratio (RR) 0.13, 95% confidence interval (CI) 0.03 to 0.50; 1 trial, 60 participants; very low-certainty evidence). The wand versus conventional treatment: the evidence was uncertain regarding the effect of the wand on pain-related behaviour during delivery of LA. Four studies reported a benefit in using the wand while the remaining studies results suggested no difference between the two methods of delivering LA (six trials, 704 participants; very low-certainty evidence). Counter-stimulation/distraction versus conventional treatment: the evidence was uncertain for the outcome pain experience during delivery of LA with children experiencing less pain when counter-stimulation was used (RR 0.12, 95% CI 0.04 to 0.34; 1 trial, 134 participants; very low-certainty evidence). Hypnosis versus conventional treatment: the evidence was uncertain for the outcome pain experience during delivery of LA with participants in the hypnosis group experiencing less pain (mean difference (MD) -1.79, 95% CI -3.01 to -0.57; 1 trial, 29 participants; very low-certainty evidence). Other comparisons considered included pre-cooling of the injection site, the wand versus Sleeper One, the use of a camouflage syringe, use of an electrical counter-stimulation device, and video modelling acclimatisation, and had a single study each. The findings from these other comparisons were insufficient to draw any affirmative conclusions about their effectiveness, and were considered to be very low-certainty evidence.

AUTHORS' CONCLUSIONS

We did not find sufficient evidence to draw firm conclusions as to the best interventions to increase acceptance of LA in children due to variation in methodology and nature/timing of outcome measures. We recommend further parallel RCTs, reported in line with the CONSORT Statement. Care should be taken when choosing outcome measures.

Brazilian Scientific Research about Acupuncture in Dentistry: Bibliometric Analysis of the Papers Presented at SBPqO Meetings

AbstractThe aim of this study was to investigate the Brazilian scientific production about acupuncture in dentistry, outlining the profile of the works about the subject presented at the Meetings of the Brazilian Society of Dental Research (SBPqO). It was a cross-sectional study, with a quantitative approach, based on secondary data. An analysis of all abstracts presented in the last ten SBPqO Meetings (2009-2018) published in the annals of the event was carried out. For the research the location of the term "acupuntura" or "acupuncture" among the abstracts was realized and the following information was collected: type of institution that carried out the research (public or private), Brazilian region where it was realized, area or specialty of dentistry and whether it involved humans or animals. Of the 26,514 dental research abstracts published in the annals, only 27 papers were experimental studies or systematic reviews about the subject. Of the total, 23 (85.2%) were developed in public institutions, 15 (55.6%) did not receive financial support 20 (74.1%) were carried out in humans and 13 (48.2%) were developed in the Southeast region. Regarding the dental specialty, the majority (70.4%) investigated acupuncture in "Temporomandibular Dysfunction and Orofacial Pain". Therefore, it can be concluded that few acupuncture studies in dentistry have been developed in the last ten years in Brazil, according to the papers presented at the SBPqO Meetings. Thus, it is suggested that research on the subject be carried out and widely disseminated between the academic and professional milieu. Keywords: Acupuncture Therapy. Dental Research. Complementary Therapies. ResumoO objetivo desse estudo foi investigar a produção científica brasileira sobre a acupuntura na odontologia, traçando o perfil dos trabalhos sobre a temática apresentados nas Reuniões da Sociedade Brasileira de Pesquisa Odontológica (SBPqO). Tratou-se de um estudo transversal, com abordagem quantitativa, a partir de dados secundários.  Realizou-se uma análise de todos os resumos apresentados nas últimas dez Reuniões da SBPqO (2009-2018) publicados nos anais do evento.

Auricular Acupuncture for Pre-Exam Anxiety in Medical Students: A Prospective Observational Pilot Investigation

Objective

Auricular acupuncture (AA) is effective for the treatment of preoperative anxiety. We aimed to study the feasibility and effects of AA on exam anxiety in a prospective observational pilot study.

Methods

Healthy medical students received bilateral AA using indwelling fixed needles at points MA-IC1, MA-TF1, MA-SC, MA-AH7, and MA-T on the day before an anatomy exam. The needles were removed after the exam. Anxiety levels were measured using the State-Trait-Anxiety Inventory (STAI) and a 100 mm visual analogue scale (VAS-100) before and after the AA intervention and once again immediately before the exam. The duration of sleep on the night before the exam was recorded and compared to that over the preceding 1 week and 6 months (all through students’ recollection). In addition, blood pressure, heart rate and the acceptability of AA to the students were recorded.

Results

Ten students (all female) were included in the final analysis. All tolerated the needles well and stated they would wish to receive AA again for exam anxiety in the future. Exam anxiety measured using both STAI and VAS-100 decreased by almost 20% after AA.

Conclusions

AA was well accepted, the outcome measurement was feasible, and the results have facilitated the calculation of the sample size for a subsequent randomised controlled trial.

Reducing Anxiety and Improving Engagement in Health Care Providers Through an Auricular Acupuncture Intervention

BACKGROUND

Stress and anxiety are experienced by health care providers as a consequence of caregiving and may result in physical, emotional, and psychological outcomes that negatively impact work engagement.

AIM

The purpose of this study was to determine whether auricular acupuncture can reduce provider anxiety and improve work engagement.

METHODS

Study participants received 5 auricular acupuncture sessions within a 16-week period utilizing the National Acupuncture Detoxification Association protocol for treating emotional trauma. Each participant completed the State-Trait Anxiety Inventory and the Utrecht Work Engagement Scale (UWES-9) prior to their first session and again after their fifth treatment.

RESULTS

Significant reductions were found in state and trait anxiety (State-Trait Anxiety Inventory), as well as significant increases in the overall scores on the UWES as compared with baseline. Only the dedication subcategory of the UWES showed significant improvement.

CONCLUSIONS

Engagement has been linked to increased productivity and well-being and improved patient and organizational outcomes. Providing effective strategies such as auricular acupuncture to support health care providers in reducing anxiety in the workplace may improve engagement.

Effects of auriculotherapy and midazolam for anxiety control in patients submitted to third molar extraction

Anxiety is common and still represents a barrier to appropriate professional care for patients requiring dental treatment. The aim of this study was to compare the effects of auriculotherapy and midazolam for the control of anxiety in patients submitted to third molar extractions. This was a randomized, double-blind, controlled, crossover clinical trial. Thirty healthy volunteers requiring bilateral third molar extraction received midazolam 15mg (oral) and sham auriculotherapy during one session, and a placebo tablet (oral) and auriculotherapy during the other; the sessions were randomized. The level of anxiety was assessed through questionnaires and physical parameters (blood pressure, heart rate, and oxygen saturation (SpO₂)) at three time points: baseline, on the day of surgery, and at follow-up. No significant differences between the protocols were observed for blood pressure and SpO₂. Auriculotherapy induced a lower heart rate than midazolam during some periods. Auriculotherapy induced more events remembered after surgery than midazolam (P<0.0001). More undesirable effects were observed with midazolam (P<0.0001). However, patient preference for auriculotherapy (53.3%) was not higher than preference for midazolam (46.7%). Auriculotherapy showed an anxiolytic effect equivalent to the midazolam effect, without the undesirable effects usually attributed to the benzodiazepine.

Effects of Auricular Acupressure on Pain Management: A Systematic Review

OBJECTIVE

Nearly half of hospitalized patients in the United States have reported experiencing pain even while undergoing treatment for pain. Analgesic use is the most common type of treatment for pain management. Many patients who experience pain seek nonpharmacologic interventions to manage their pain, including forms of complementary or alternative medicine such as auricular acupressure (AA).

DESIGN

This study conducted the first systematic review of the studies that have evaluated the effect of AA as an adjunct on pain management.

DATA SOURCES

We searched PubMed, CINAHL, Embase, Google Scholar, and Wiley for randomized controlled trials on AA.

REVIEW/ANALYSIS METHODS

The pain outcomes were pain severity and analgesic consumption. Methodologic quality was also evaluated. Fifteen randomized controlled trials were included in this analysis.

RESULTS

Twelve studies reported statistically significant improvement in the pain outcomes of AA treatment compared with the sham or standard care groups. When methodologic quality was assessed, the selected studies had medium quality, but there was a lack of high quality. This supports that the use of AA for patients may enhance self-management for their pain. However, the small number of studies and the lack of consistent rigorous methodology across the studies preclude definitive statements regarding the effectiveness of AA.

CONCLUSION

The nursing implications based on this review is that education about AA and complementary or alternative medicine therapies for health care providers may assist them in providing pain control for their patients. In addition, we need to continue research to build on evidence on the effect of AA on pain management.

Auricular acupuncture for treatment of preoperative anxiety in patients scheduled for ambulatory gynaecological surgery: a prospective controlled investigation with a non-randomised arm

OBJECTIVE

Auricular acupuncture (AA) is a promising alternative treatment for situational anxiety. The aim of this pilot investigation was to test the acceptability and feasibility of AA as a treatment for preoperative anxiety (PA) in preparation for a subsequent randomised controlled trial.

METHODS

AA was offered for treatment of PA to female patients who were scheduled for ambulatory gynaecological surgery. In patients who agreed, indwelling fixed needles were applied bilaterally at the points MA-IC1, MA-TF1, MA-SC, MA-AH7 and MA-T the day before surgery. Patients who declined AA but agreed to be examined constituted the control group (no intervention). State anxiety (primary outcome) was measured using the State-Trait-Anxiety Inventory (STAI) before AA (time I), the evening before surgery (time II) and immediately before surgery (time III). Anxiety was measured with a 100 mm visual analogue scale (VAS-100); heart rate, blood pressure and serum cortisol were also quantified.

RESULTS

Data from 62 patients (32 with AA and 30 with no intervention) were analysed. Whereas preoperative anxiety was reduced after AA the evening before surgery (P<0.01), anxiety levels in the control group increased from the first to the last measurement (P<0.001). Secondary outcomes were comparable between the patients from both groups.

CONCLUSIONS

AA was acceptable and feasible as a treatment for preoperative anxiety. The results were used for the sample size calculation of a subsequent randomised controlled clinical trial.

Acupuncture and electroacupuncture for anxiety disorders: A systematic review of the clinical research

Anxiety disorders are one of the most common mental health concerns with a major contribution to the global burden of disease. When not treated, anxiety can be aggravated to more serious and complicated health problems. Pharmacology and psychotherapy stand for the conventional treatment for anxiety disorders but these present limited efficacy, especially in the case of chronic anxiety, with high relapse rates and often causing adverse side effects. Clinical research studies render acupuncture as a valid treatment therapy for anxiety disorders without significant adverse effects. The objective of this paper is to review the literature on the effectiveness of acupuncture and electroacupuncture for the treatment of patients with anxiety disorders in order to find strong scientific evidence for its regular practice in Western culture. The systematic review of the clinical research was focused on published clinical trials (controlled, randomized and non-randomized) regarding the treatment of anxiety with acupuncture. Only clinical trials where anxiety was treated as the therapeutic target, and not as a secondary measurement or being associated with other health condition or disease, were considered. Two authors extracted the data independently and exclusion and inclusion criteria were set. The search rendered 1135 papers addressing anxiety as a primary therapeutic target. After review, 13 papers were identified to match exclusion and inclusion criteria and were selected for this analysis. Methodology, design, and quality of the research were highly variable and are discussed and compared. Overall, there is good scientific evidence encouraging acupuncture therapy to treat anxiety disorders as it yields effective outcomes, with fewer side effects than conventional treatment. More research in this area is however needed.

[Is supplemental ear acupuncture for surgical tooth removal with local anesthesia effective? : A pilot study]

BACKGROUND

The application of ear acupuncture can contribute to a reduction of acute pain. Data on the application of ear acupuncture following oral surgery in odontology is insufficient.

OBJECTIVE

This study investigated the effectiveness of ear acupuncture as an auxiliary analgesic treatment in addition to local anesthesia for operative tooth removal.

METHODS

In this prospective open non-randomized pilot study (in accordance with the CONSORT publication) 2 cohorts of 50 patients each with the indications for an operative tooth removal either with or without the application of ear acupuncture in addition to local anesthesia with articain were observed. Patients were allocated to the groups according to their preference. Pain intensity while resting and while chewing was recorded as the primary parameter for a period of 10 days. The secondary parameters were the subjective experience of anxiety and symptoms, such as headaches, dizziness and nausea.

RESULTS

The two groups did not differ significantly with respect to demographic variables or the use of local anesthetics. At the various measurement intervals, pain intensity while resting or chewing differed significantly between the two groups (ANOVA, p = 0.004, p = 0.007, respectively). Furthermore, the experience of anxiety (ANOVA, p = 0.0001), the number of patients taking analgesics (χ²-test, p = 0.017) and the total postoperative consumption of analgesics (t-test, 0.001) revealed significant differences. In both groups the numerical rating scales (NRS) for postoperative headaches, dizziness and nausea were low.

DISCUSSION AND CONCLUSION

Despite a potential bias and methodological limitations of the study design, the results of this investigation suggest that ear acupuncture influences the experience of pain and anxiety in the postoperative period after tooth removal. As a treatment method with low adverse effects ear acupuncture can contribute to postoperative pain control, especially in patients with preoperative anxiety.

Auricular Acupuncture for Exam Anxiety in Medical Students-A Randomized Crossover Investigation

Auricular acupuncture (AA) is effective in the treatment of preoperative anxiety. The aim was to investigate whether AA can reduce exam anxiety as compared to placebo and no intervention. Forty-four medical students were randomized to receive AA, placebo, or no intervention in a crossover manner and subsequently completed three comparable oral anatomy exams with an interval of 1 month between the exams/interventions. AA was applied using indwelling fixed needles bilaterally at points MA-IC1, MA-TF1, MA-SC, MA-AT1 and MA-TG one day prior to each exam. Placebo needles were used as control. Levels of anxiety were measured using a visual analogue scale before and after each intervention as well as before each exam. Additional measures included the State-Trait-Anxiety Inventory, duration of sleep at night, blood pressure, heart rate and the extent of participant blinding. All included participants finished the study. Anxiety levels were reduced after AA and placebo intervention compared to baseline and the no intervention condition (p < 0.003). AA was better at reducing anxiety than placebo in the evening before the exam (p = 0.018). Participants were able to distinguish between AA and placebo intervention. Both AA and placebo interventions reduced exam anxiety in medical students. The superiority of AA over placebo may be due to insufficient blinding of participants.

The History, Mechanism, and Clinical Application of Auricular Therapy in Traditional Chinese Medicine

Auricular therapy includes acupuncture, electroacupuncture, acupressure, lasering, cauterization, moxibustion, and bloodletting in the auricle. For 2500 years, people have employed auricular therapy for treating diseases, but the methods have been limited to bloodletting and cauterization. Only after 1957, the international scientific community became aware that the map of the ear resembles an inverted fetus, its introduction has led to auricular acupuncture (AA) becoming a more systemic approach, and, following the identification and standardization of more precise points, AA has been employed in clinical applications. The mechanisms of AA are considered to have a close relationship with the autonomic nervous system, the neuroendocrine system, neuroimmunological factors, neuroinflammation, and neural reflex, as well as antioxidation. Auricular therapy has been applied, for example, for pain relief, for the treatment of epilepsy, anxiety, and obesity, and for improving sleep quality. However, the mechanisms and evidence for auricular therapy warrant further study.

Measuring mechanical pain: the refinement and standardization of pressure pain threshold measurements

Pain thresholds are widely used in behavioral research, but unlike other pain modalities, a standardized assessment of pressure pain remains a challenge. In this research, we describe the application of an automatic pressure algometer with a linear increase in force. Ergonomically designed fixation devices were developed to increase the accuracy and to shorten the time of each measurement. Ten healthy volunteers were included in a pilot study to test the algometry method. Pressure pain thresholds (PPTs) were investigated over 2 experimental days in three nonconsecutive runs at 29 measurement sites. During the experiment, subjects reported their subjective sleepiness, level of state-anxiety, psychological status and the perceived pain intensity of each measurement. Pain intensity ratings indicate that instructions were followed. State-anxiety and subjective sleepiness levels were low throughout the experiment. The method has proven to be suitable for standardized PPT measurements across the body in an ergonomic, safe, and user-friendly fashion.

Ear acupressure for perennial allergic rhinitis: A multicenter randomized controlled trial

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.

Acupressure and anxiety in cancer patients

Background:

Anxiety has negative effects on mental and physical performance, quality of life, duration of hospitalization, and even on the treatment of patients with cancer.

Objectives:

Today acupressure is widely used to treat anxiety. Thus, the present study aimed to investigate the effects of acupressure on anxiety in patients with cancer.

Patients and Methods:

A double-blind randomized clinical trial was conducted on 85 patients hospitalized with 3 groups including acupressure group (n = 27), sham group (n = 28), and control group (n = 30) in the hematologic ward of Shahid Beheshti Hospital of Hamadan, Iran, in 2013. The sampling permuted-block randomization with triple block was used. The anxiety of the patients in the experimental, sham, and control groups were measured with Spielberger’s State-Trait Anxiety Inventory (STAI). Then, real acupressure was performed in the experimental group and fake acupressure in the sham group, and only routine care was provided for the control group. Anxiety of the patients was also assessed at 5 and 10 days after the intervention. Statistical analysis of the data was performed by SPSS software using repeated measures analysis of variance (ANOVA) and post hoc least significant difference (LSD) test.

Results:

According to the findings, the mean level of anxiety before the intervention between groups were matched (P > 0.05). Acupressure had a significant influence on the anxiety in the experimental group at 5 (45.30 ± 7.14) and 10 days (43.48 ± 6.82) after the intervention (P < 0.05). However, it did not have a significant impact on their covert anxiety (45.48 ± 7.92 at 5^th day vs 45.63 ± 8.08 at 10th day, P > 0.05). No significant differences were observed in the fake points regarding overt and covert anxiety of patients in the sham group (overt anxiety; 47.57 ± 7.85 at 5^th day vs. 46.71 ± 7.32 at 10^th day, P > 0.05) (covert anxiety; 47.96 ± 6.33 at 5^th day vs. 46.89 ± 6.94 at 10^th day, P > 0.05). Moreover, the routine care provided for the control group did not have any effect on the overt and covert anxiety of the patients (P > 0.05).

Conclusions:

Acupressure is recommended as a complementary therapy to reduce anxiety in patients with cancer because of its low cost, safety, and simplicity.

Adverse events of auricular therapy: a systematic review

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.

Efficacy of acupuncture in reducing preoperative anxiety: a meta-analysis

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.

Randomised clinical trial of five ear acupuncture points for the treatment of overweight people

OBJECTIVE

To evaluate the efficacy of the five ear acupuncture points (Shen-men, Spleen, Stomach, Hunger, Endocrine), generally used in Korean clinics for treating obesity, and compare them with the Hunger acupuncture point.

METHODS

A randomised controlled clinical trial was conducted in 91 Koreans (16 male and 75 female, body mass index (BMI)≥23), who had not received any other weight control treatment within the past 6 months. Subjects were divided randomly into treatment I, treatment II or sham control groups and received unilateral auricular acupuncture with indwelling needles replaced weekly for 8 weeks. Treatment I group received acupuncture at the five ear acupuncture points, treatment II group at the Hunger acupuncture point only and the sham control group received acupuncture at the five ear acupuncture points used in treatment I, but the needles were removed immediately after insertion. BMI, waist circumference, weight, body fat mass (BFM), percentage body fat and blood pressure were measured at baseline and at 4 and 8 weeks after treatment.

RESULTS

For the 58 participants who provided data at 8 weeks, significant differences in BMI, weight and BFM were found between the treatment and control groups. Treatment groups I and II showed 6.1% and 5.7% reduction in BMI, respectively (p<0.004). There were no significant differences between the two treatment groups.

CONCLUSIONS

This finding suggests that the five ear acupuncture points, generally used in Korean clinics, and the Hunger point alone treatment are both effective for treating overweight people.

Gag reflex control through acupuncture: a case series

BACKGROUND

Many patients avoid dental appointments because of severe gagging when they have work performed, such as taking impressions. There are several methods known to alleviate gagging, and some studies have suggested that acupuncture may be effective in reducing gag reflex. The aim of the present study therefore was to evaluate whether acupuncture can produce a reduction of the gag reflex.

METHODS

A total of 20 patients, aged between 19 and 80 years, with history of gag reflex on taking dental impressions, were recruited. All patients fulfilling the inclusion criteria had an upper and lower dental alginate impression taken without acupuncture, and a second upper and lower alginate impression taken immediately after acupuncture based on traditional Chinese medicine. After each impression, the patients recorded their emetic sensation using a visual analogue scale (VAS).

RESULTS

The results showed a significant (p<0.05) reduction in the gag reflex scores after acupuncture. For upper impressions, they fell from 6.8 (1.1) to 1.1 (1.1); and for lower impressions, from 5.45 (1.0) to 0.4 (0.7) (mean (SD)).

CONCLUSIONS

The findings from our study suggest that acupuncture may be useful for preventing and treating gag reflex, and justifies further study.

Sham control methods used in ear-acupuncture/ear-acupressure randomized controlled trials: a systematic review

Ear-acupuncture/ear-acupressure (EAP) has been used for a range of health conditions with numerous randomized controlled trials (RCTs) investigating its efficacy and safety. However, the design of sham interventions in these RCTs varied significantly. This study systematically reviewed RCTs on EAP for all clinical conditions involving a number of sham EAPs as a control intervention. The review is guided by the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0 and investigated the types and differences of sham EAP interventions. Four electronic English databases (The Cochrane Library, PubMed, Embase, CINAHL®) and two Chinese databases (CQVIP, CNKI) were searched in December 2012 and 55 published RCTs comparing real and sham EAP for any clinical condition were included. Characteristics of participants, real and sham interventions, and outcomes were extracted. Four types of sham methods were identified. Among the 55 RCTs, 25 studies involved treatment on nonspecific ear acupoints as the sham method; seven studies used nonacupoints on the ear; nine studies selected placebo needles or placebo ear-acupressure on the same ear acupoints for the real treatment; 10 studies employed pseudo-intervention; and five studies combined two of the above methods to be the sham control. Other factors of treatment such as number of points, treatment duration, and frequency also varied greatly. Risk of bias assessment suggests that 32 RCTs were "high risk" in terms of participants blinding, and 45 RCTs were "high risk" in terms of personnel blinding. Meta-analysis was not conducted due to the high clinical heterogeneity across included studies.

Auricular acupuncture with laser

Auricular acupuncture is a method which has been successfully used in various fields of medicine especially in the treatment of pain relief. The introduction of lasers especially low-level lasers into medicine brought besides the already existing stimulation with needles and electricity an additional technique to auricular acupuncture. This literature research looks at the historical background, the development and the anatomical and neurological aspects of auricular acupuncture in general and auricular laser acupuncture in detail. Preliminary scientific findings on auricular acupuncture with laser have been described in detail and discussed critically in this review article. The results of the studies have shown evidence of the effect of auricular laser acupuncture. However, a comparison of these studies was impossible due to their different study designs. The most important technical as well as study parameters were described in detail in order to give more sufficient evidence and to improve the quality of future studies.
