The Chinese Ear Shenmen Point and the French Cosmonaut Point: Same or Different?

The Shenmen Point is an auricular acupuncture point that is also known in France as the Cosmonaut Point. It is widely utilized therapeutically for its property of reducing stress. In some ways it is a controversial point. Differences of opinion exist regarding the most appropriate name of the point, who discovered it first, its location within the triangular fossa, its best method of detection, its best method of stimulation, its actions, its indications, its contraindications, its therapeutic effects, and even its very existence. Furthermore, given the extent of controversy concerning the Shenmen and Cosmonaut points, one may reasonably question if they represent the same point, or two separate points. The aim of this report will be to review the similarities and differences of opinion regarding the Shenmen and Cosmonaut points, drawing mainly from French, German, Chinese, and American sources. The clinical implications of these comparisons will be summarized.

Understanding the effect of acupuncture on nausea and vomiting during pregnancy from a metabolic perspective: study protocol for a single-blinded randomized controlled trial

BackgroundAcupuncture is an effective complementary therapy for nausea and vomiting during pregnancy (NVP). Nevertheless, the utilization of acupuncture for NVP has been minimally explored in current scholarly research, with a paucity of systematic randomized clinical trials (RCTs) in it. We aim to evaluate the effects of acupuncture on NVP after assisted reproductive techniques (ART) and explore the metabolism-related mechanism of the efficacy.MethodsThis single-blind, randomized, controlled trial will randomize 68 patients with NVP after ART to a traditional acupuncture (tACP) or a sham acupuncture (sACP) group. The tACP group will receive tACP thrice a week for 2 weeks with a day interval between sessions, while the sACP group will undergo the same number of nonpenetrative acupuncture at non-acupoints for the same period. Pregnancy-specific quantification of emesis will be used to evaluate symptom severity. Routine blood and urine tests, liver and kidney function tests, human chorionic gonadotropin, nuchal translucency thickness, and embryonic development measured using ultrasound will be used to evaluate safety during pregnancy. Non-targeted metabolomic analysis will be performed to explore the association between metabolic changes and clinical symptoms.DiscussionThis study will elucidate the effects and safety of acupuncture in treating NVP in women undergoing ART. The results of this study will contribute to optimizing acupuncture therapies by combining the body and auricular points and exploring the underlying therapeutic mechanism using a metabolomics approach.Trial registrationChinese Clinical Trial Registry, ChiCTR2300075259.

Influence of muscle regions of meridians needling method combined with auricular point sticking on pain and range of motion in patients with chronic nonspecific low back pain

Multi-level exploration of auricular acupuncture: from traditional Chinese medicine theory to modern medical application.

As medical research advances and technology rapidly develops, auricular acupuncture has emerged as a point of growing interest. This paper delves into the intricate anatomy of auricular points, their significance and therapeutic principles in traditional Chinese medicine (TCM), and the underlying mechanisms of auricular acupuncture in contemporary medicine. The aim is to delve deeply into this ancient and mysterious medical tradition, unveiling its multi-layered mysteries in the field of neurostimulation. The anatomical structure of auricular points is complex and delicate, and their unique neurovascular network grants them a special status in neurostimulation therapy. Through exploration of these anatomical features, we not only comprehend the position of auricular points in TCM theory but also provide a profound foundation for their modern medical applications. Through systematic review, we synthesize insights from traditional Chinese medical theory for modern medical research. Building upon anatomical and classical theoretical foundations, we focus on the mechanisms of auricular acupuncture as a unique neurostimulation therapy. This field encompasses neuroregulation, pain management, psychological wellbeing, metabolic disorders, and immune modulation. The latest clinical research not only confirms the efficacy of auricular stimulation in alleviating pain symptoms and modulating metabolic diseases at the endocrine level but also underscores its potential role in regulating patients' psychological wellbeing. This article aims to promote a comprehensive understanding of auricular acupuncture by demonstrating its diverse applications and providing substantial evidence to support its broader adoption in clinical practice.

Ipsilateral stimulation shows somatotopy of thumb and shoulder auricular points on the left primary somatosensory cortex using high-density fNIRS.

Auriculotherapy is a technique based on stimulation applied to specific ear points. Its mechanism of active and clinical efficacy remain to be established. This study aims to assess the role that primary somatosensory cortex may play to validate auriculotherapy mechanisms. This study examined whether tactile stimulation at specific auricular points is correlated with distinct cortical activation in the primary somatosensory cortex. Seventeen healthy adults participated in the study. Tactile stimuli were delivered to the thumb, shoulder, and skin master points on the ear using von Frey filaments. Functional near-infrared spectroscopy was used to measure and spatially map cortical responses. This study revealed distinct hemodynamic activity patterns in response to ear point stimulation, consistent with the classic homunculus model of somatotopic organization. Ipsilateral stimulation showed specific cortical activations for the thumb and shoulder points, while contralateral stimulation showed less significant activity. Functional near-infrared spectroscopy effectively captured localized cortical responses to ear tactile stimuli, supporting the somatotopic mapping hypothesis. These findings enhance the understanding of sensory processing with auricular stimulation and supports the concepts of auricular cartography that underpins some schools of auriculotherapy practice. Future research should explore bilateral cortical mapping and the integration of other neuroimaging techniques.

Application of buried auricular point combined with Wenjing Sanhan prescription in arteriosclerosis obliterans patients with resting pain.

Research on the combined use of ear acupoint embedding beans and warming meridians with cold-dispersing formulas for alleviating resting pain in patients with arteriosclerosis obliterans (ASO) remains limited. To explore the therapeutic efficacy of auricular point embedding beans combined with Wenjing Sanhan prescription in alleviating resting pain in patients with lower-limb ASO. A total of 100 patients with ASO experiencing resting pain who were treated at our hospital from January 2022 to January 2023 were enrolled. They were randomly allocated into two groups using a double-blind approach. The control group was treated using a warming meridian with a cold-dispersing formula, while the study group received additional treatment with ear acupoint embedding beans. The clinical efficacy, ankle-brachial artery pressure ratio, hemorheological indicators, and traditional Chinese medicine symptom scores were compared between the two groups. The clinical efficacy rate in the study group was significantly higher (94.00%) than that in the control group (72.00%, P < 0.05). Moreover, the ankle-brachial artery pressure ratio was significantly higher in the study group after treatment (P < 0.05). Hemorheological parameters, including whole blood viscosity, plasma viscosity (1.83 ± 0.11) mPa/s, fibrinogen levels (3.30 ± 0.21) g/L, platelet adhesion rate (49.87% ± 10.51%), and erythrocyte aggregation index (1.79 ± 0) were improved in the study group compared to the control group. In addition, the scores for decreased skin temperature (1.41 ± 0.26), intermittent claudication (1.30 ± 0.20), and resting pain (1.23 ± 0.31) were significantly lower in the study group than those in the control group (all P < 0.05). The level of oxidative stress in the study group also exhibited significant improvement (P < 0.05), and the levels of inflammatory factors were considerably lower than those in the control group. The combination of ear point embedding beans and Wenjing Sanhan prescription demonstrates promising clinical efficacy in alleviating resting pain associated with ASO.

Transcranial Magnetic Stimulation Combined with Auricular Point Pressure Bean on Emotional Disorders in Elderly Patients after Intracerebral Hemorrhage Surgery: A Retrospective Cohort Study.

To investigate whether the combination of repetitive transcranial magnetic stimulation (rTMS) and auricular point pressure bean could effectively ameliorate postoperative affective disorder in elderly patients suffering from cerebral hemorrhage. From June 2020 to September 2023, 116 elderly patients with depression after cerebral hemorrhage, who underwent surgical procedures were divided into the exposure group and the control group. The division was determined based on whether received rTMS and traditional Chinese medicine auricular point pressure bean therapy. Hamilton anxiety scale (HAMA), Hamilton Depression scale (HAMD), National Institutes of Health Stroke scale (NIHSS), Montreal Cognitive Assessment scale (MoCA) and Mini Mental State examination scale (MMSE) were collected and compared between before intervention and after intervention. In accordance with a 1 : 1 matching ratio, the patients in the study were paired using propensity score matching (PSM), with 53 patients in both the exposure group and the control group. There were no notable differences in baseline characteristics between the 2 groups (P > .05). Following the intervention, the HAMA score and the NIHSS score of the exposure group were markedly lower than those of the control group (P < .001). Additionally, theMoCA scores (P = .001) and MMSE scores (P < .001) in the exposure group were significantlyhigher. The difference score have a significant difference in HAMA score (P = .001), NIHSS score (P < .001), MoCA (P < .001) and MMSE scores (P < .001). The combination of rTMS therapy and auricular point pressure bean therapy in traditional Chinese medicine demonstrates can effectively relieve the anxiety level, postoperative emotional and cognitive disorders of elderly patients after intracerebral hemorrhage, and provide certain ideas and support for clinical treatment.

Effects of Shugan Tiaoshen intradermal needling intervention on attentional networks in subthreshold depression: a randomized controlled trial

To analyze the effects of Shugan Tiaoshen (regulating liver and harmonizing spirit) intradermal needling protocol on the attentional networks of patients with subthreshold depression using the attention network test (ANT). Eighty patients with subthreshold depression were randomly divided into an intradermal needling group (40 cases) and a sham needling group (40 cases, 2 cases dropped out), with an additional 43 healthy subjects as a normal group. The intradermal needling group received intradermal needling treatment, while the sham needling group received sham intradermal needling, with the needle tip not penetrating the skin. The bilateral Xinshu (BL 15), Ganshu (BL 18), Shentang (BL 44) as well as auricular points Xin (CO15) and Gan (CO12) were selected alternately. Treatments were administered twice a week for a total of 6 weeks in the two groups. The patient health questionnaire-9 (PHQ-9) and generalized anxiety disorder (GAD-7) scores were observed before treatment, after 3 weeks of treatment, after treatment, and at 1 month after the end of treatment (follow-up), and the ANT of the two groups of patients with subthreshold depression before and after treatment as well as the normal group of healthy subjects was compared. The PHQ-9 and GAD-7 scores of the patients with subthreshold depression were decreased after 3 weeks of treatment, after treatment, and in follow-up in the two groups (P<0.05), the differences in PHQ-9 and GAD-7 scores before and after treatment were greater in the intradermal needling group than those in the sham needling group (P<0.01). Before treatment, the executive control network reaction time of the subthreshold depression group (the intradermal needling group and the sham needling group) was higher than that of the normal group (P<0.05). Compared before treatment, the executive control network reaction time of the patients in the intradermal needling group and the sham needling group was decreased after treatment (P<0.05), and the alerting network reaction time of the intradermal needling group was increased after treatment (P<0.05); the difference in alerting network reaction time before and after treatment was greater in the intradermal needling group than that of the sham needling group (P<0.01). Regulating liver and harmonizing spirit intradermal needling protocol could effectively improve depressive and anxious symptoms in patients with subthreshold depression, and enhance the efficiency of the alerting network.

Morphometric Analysis of the Sternocleidomastoid Muscle and Associated Anatomical Landmarks: Implications for Surgical Procedures and Clinical Practice

Abstract Background: Sternocleidomastoid (SCM) a chief rotator and flexor of the neck divides the side of the neck into anterior and posterior triangles and acts as an important landmark for clinicians. It protects the vital structures of the neck such as the cervical plexus and vessels. The depression between the two heads of SCM, the lesser supraclavicular fossa is used by clinicians as a landmark for various procedures. Methodology: The study included 15 males and 6 females cadavers, in the Anatomy Department, at Kasturba Medical College, Manipal. The parameters measured were SCM length along the anterior and posterior border, mastoid tip to the exit of greater auricular nerve and spinal accessory nerve along the posterior border of SCM, and origin of superior thyroid artery to SCM origin along the posterior border. Results: SCM length along the anterior border was 19.91 cm and 16.48 cm in males and females, respectively. Along the posterior border was 16.04 cm and 13.88 cm. Greater auricular nerve point of exit to the mastoid tip is 7.29 cm and 5.93 cm in males and females respectively. All results were more in males compared to females. Conclusion: This detailed morphometric analysis of the sternocleidomastoid (SCM) muscle offers important insights into its anatomical relationships and variations, which are crucial for clinical practice. The gender-specific measurements of SCM length, nerve exit points, and vascular landmarks provide surgeons with precise anatomical guidance for procedures in the neck area.

Auricular point acupressure for managing postoperative pain and reducing anxiety in patients with perianal abscesses

ObjectiveThe objective of this study is to assess the efficacy of auricular point acupressure in relieving postoperative pain and reducing anxiety among patients with perianal abscesses. MethodsWe included 61 patients with perianal abscesses who were admitted to the Nantong First People's Hospital between July 2019 and June 2020 and were scheduled to undergo one-stage radical surgery. We divided them into the treatment group (n = 31), where patients were administered preoperative auricular acupressure targeting the bilateral Shenmen, subcortical, and other points. They were instructed to apply pressure five to six times per day, each time for about 3–5 min. Patients in the control group (n = 30) received routine preoperative preparation. The treatment duration for both groups was one week. We compared the two groups using the pain visual analog scale (VAS) scores, the use of additional postoperative analgesics, and scores on the Hamilton anxiety and depression scales pre- and post-surgery at 6 h, 24 h, 48 h, 72 h, and 1 week after surgery, as well as at the time of the first bowel movement. ResultsPatients in the treatment group reported lower VAS scores than those of the control group at 48 h, 72 h, 1 week, and at the first defecation post-surgery, and the differences were statistically significant (all P < 0.05). Additional postoperative analgesics were used in seven patients in the treatment group (22.58 %) and in 10 patients in the control group (33.33 %). The difference between the two groups was not statistically significant (χ2 = 0.88, P = 0.35). Postoperative scores for the Hamilton Anxiety Rating Scale (HAM-A) and the Hamilton Depression Rating Scale (HAM-D) in the treatment group were significantly lower than those in the control group (P < 0.05). ConclusionThe results of this study demonstrated that auricular point acupressure was effective in alleviating postoperative pain in patients with perianal abscesses and simultaneously reduced their postoperative psychological stress reactions. This dual effect provided both pain relief and a reduction of anxiety with fewer adverse reactions, making it a safe and effective treatment option.

Effect of Auriculotherapy on Stress: A Systematic Review and Meta-Analysis.

Background: Auriculotherapy, a form of therapy that involves stimulating specific points on the ear auricle, has garnered attention for its potential in holistic stress management in adults, aligning with broader patient-centered therapeutic approaches. Objective: The aim of this study was to evaluate the effectiveness of auriculotherapy for stress relief in adults. Methods: A comprehensive search of nine databases (PubMed, Scopus, CINAHL, Web of Science, Ovid Medline, Cochrane Library, RISS, KMbase, and KISS) was performed, yielding 553 studies. Of these, 12 were selected for meta-analysis based on the inclusion criteria, which considered demographic data, types of auriculotherapy, intervention characteristics, auricular points, and stress-related outcomes. The risk of bias was also evaluated for each selected study. Results: The meta-analysis results (n = 12) indicated that auriculotherapy was significantly superior to the control group in terms of subjective stress index, blood pressure, heart rate variability, and pulse rate, as well as improving low-frequency (LF) and high-frequency (HF) heart rate components and their ratio (LF/HF) in adults. Additionally, the subgroup analysis indicated a trend where the effect size of acupressure may be larger than that of acupuncture. Conclusions: Our findings underscore auriculotherapy's efficacy in reducing stress in adults, advocating for its integration into nursing curriculums as a viable clinical intervention for stress management. Promoting its application in clinical environments could complement holistic, patient-centric care paradigms.

Adapting and Evaluating a Theory-Driven, Non-Pharmacological Intervention to Self-Manage Pain.

The existing literature has limited detail on theory-driven interventions, particularly in pain studies. We adapted Bandura's self-efficacy framework toward a theory-driven, non-pharmacological intervention using auricular point acupressure (APA) and evaluated participants' perceptions of this intervention on their pain self-management. APA is a non-invasive modality based on auricular acupuncture principles. We mapped our study intervention components according to Bandura's key sources of self-efficacy (performance accomplishments, vicarious experience, verbal persuasion, and emotional arousal) to facilitate the self-management of pain. Through a qualitative study design, we conducted virtual interviews at one and three months after a 4-week APA intervention among 23 participants using purposive sampling to describe their experiences in managing their pain based on our theory-driven APA intervention. Using thematic analyses, we found four themes: the enhanced self-management of pain, improved pain outcomes, the feasibility of technology, and the sustainability of APA. Describing how interventions are mapped according to the elements of theoretical frameworks can help to guide intervention development, advance science and knowledge development, and promote the implementation of interventions. As such, using Bandura's self-efficacy theory as a foundation for the APA intervention, APA was found to be feasible and sustainable, improving self-management, pain intensity, and pain-related outcomes. Participants provided recommendations for the further improvement of this theory-driven intervention.

Intervention of hypertension by acupuncture-related therapies: A network meta-analysis.

The prevalence of essential hypertension contributed significantly to morbidity and mortality rates. Acupuncture-related therapies were commonly employed in hypertension treatment. Nevertheless, a lack of conclusive evidence left uncertainties regarding the optimal strategies for managing hypertensive populations. Conduct a comprehensive systematic review to evaluate the existing clinical evidence about the effectiveness of acupuncture and moxibustion-related therapies in managing hypertension, by employing network meta-analysis techniques. A comprehensive electronic search was conducted across n of databases. This search covered studies available up to October 2022. Randomized controlled trials assessing acupuncture and moxibustion-related therapies in managing hypertension based on traditional Chinese medicine were screened. Primary outcome measures included the antihypertensive effectiveness rate, variations in blood pressure and the incorporation of Traditional Chinese Medicine (TCM) syndrome manifestations. The review follows the guidelines outlined in the PRISMA statement. We identified a total of 24 trials with 1867 patients, which evaluated the efficacy of various acupuncture-related therapies for hypertension management. Network meta-analysis showed that moxibustion and auricular point sticking combined with medication therapy had the best effect in terms of antihypertensive effective rate (medication + moxibustion + auricular pressure vs. medication = 1.29 [1.09, 1.54]; sucra = 85.9, p < .05) and hypertension symptom improvement (medication + moxibustion + auricular pressure vs. medication = -1.55 [-2.98, -0.13]; sucra = 96.1, p < .05). Acupuncture combined with moxibustion combined with medication therapy had the best effect in reducing systolic pressure (medication + moxibustion + acupuncture vs. medication = -8.50 [-10.19, -6.80]; sucra = 100, p < .05) and diastolic blood pressure (medication + moxibustion + acupuncture versus medication = -4.72 [-6.71, -2.72]; sucra = 99.71, p < 0.05). Network meta-analysis suggested that the combined use of moxibustion and auricular point application in conjunction with drug therapy showed the highest likelihood of being the most effective treatment in terms of antihypertensive efficiency rates and improvement in hypertension symptoms. Furthermore, the combination of acupuncture and moxibustion alongside drug treatment emerged as the most promising approach for reducing systolic blood pressure and diastolic blood pressure. Limited by the methodological quality and quantity of the included studies, the results need to be interpreted with caution. It is necessary to conduct more high-quality randomized controlled trials of acupuncture-related therapies for the adjuvant treatment of hypertension in the future. Clinicians can use acupuncture-related therapies to inform their treatment decisions and potentially incorporate acupuncture-related therapies into their hypertension management protocols.

Auricular acupuncture plays a neuroprotective role in 6-hydroxydopamine-induced Parkinson's disease in rats

BackgroundParkinson's disease (PD) is the second-most common neurodegenerative disease. Currently, PD treatment is symptomatic and involves the use of dopamine-based therapies. This study investigated auricular acupuncture on motor and cognitive abilities in rats with 6-OHDA-induced PD. MethodsA PD rat model was established by bilaterally injecting 6-OHDA into the lateral dorsal striatum. Then, 2- or 15-Hz auricular electroacupuncture (EA) was applied to the auricular CO15 and CO12 points bilaterally for 20 min three times a week for four consecutive weeks. ResultsBoth the latency to fall and rest time of the open field test in the EA15 group were greater than in the 6-OHDA group (p < 0.001 and p < 0.05). The time spent on the two-object recognition task was greater in the EA15 group and EA2 group than in the 6-OHDA group (p < 0.01 and p < 0.05). More tyrosine hydroxylase (TH)-positive neurons and fibers were noted in the dorsolateral striatum and substantia nigra (SN) (all p < 0.05). TH expression in the SN was greater in the EA15 group than that in the 6-OHDA group (p < 0.05), while α-synuclein expression in the SN was stronger in the 6-OHDA group than in the EA15 group (p < 0.05). The l-DOPA level in the striatum was higher in the EA15 group than in the 6-OHDA group (p < 0.05). ConclusionAccording to the results, rats with 6-OHDA-induced PD may benefit from auricular EA in terms of motor and cognitive behavior as well as neuroprotection.

Pseudomyopia treated with auricular point sticking combined with periocular needle-embedding therapy and prevention of true myopia: a multicenter randomized controlled trial.

To observe the clinical effect and safety of auricular point sticking combined with periocular needle-embedding therapy for pseudomyopia and prevention of true myopia. A total of 269 children with pseudomyopia were randomized into an observation group (134 cases, 2 cases dropped out) and a control group (135 cases, 5 cases dropped out). In the control group, the healthy education was provided. In the observation group, besides the intervention as the control group, the auricular point sticking was delivered at gan (CO12), pi (CO13), xin (CO15) and yan (LO5) on one ear in each treatment, combined with periocular needle-embedding technique at bilateral Cuanzhu (BL 2), Yuyao (EX-HN 4) and Sibai (ST 2). There were 2 weeks of interval after 4 weeks of treatment. One course of treatment was composed of 6 weeks and 2 courses were required. Separately, before treatment, after 6 and 12 weeks of treatment, and after 12 weeks (the 1st follow-up visit) and 24 weeks (the 2nd follow-up visit) of treatment completion, the spherical equivalent (SE), SE progression, axial length (AL) progression, accommodative amplitude (AMP), the score of the TCM symptom and the general symptom were observed in the two groups. The safety and compliance were evaluated in the two groups. After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, SE increased when compared with that before treatment in the two groups (P<0.05), and AMP was larger than that before treatment in the observation group (P<0.05). After 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the progression of SE was slower in the observation group compared with that in the control group (P<0.01, P<0.001). After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the progression of AL in the observation group was lower than that of the control group (P<0.05, P<0.01, P<0.001); and in the 1st and 2nd follow-up visits, AMP of the observation group was larger when compared with that in the control group (P<0.05, P<0.001). After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the total scores of TCM symptom and general symptom were reduced in comparison with those before treatment in the observation group (P<0.05); after 6 and 12 weeks of treatment, the total scores of TCM symptom and general symptom were lower than those before treatment in the control group (P<0.05). In the 1st and 2nd follow-up visits, the difference of the total score of TCM symptom and general symptom in the observation group was larger than that of the control group (P<0.05). In the observation group, compared with the control group, the scores for pale/dark complexion in the 1st and 2nd follow-up visits and that for lassitude in the 2nd follow-up visit were lower (P<0.05), the score for poor concentration after 12 weeks of treatment and that for poor sleep and memory in the 2nd follow-up visit were lower (P<0.05). There were no adverse reactions in the two groups. The compliance was 98.5% in the observation group and was 96.3% in the control group, without statistical difference (P>0.05). On the basis of health education, auricular point sticking combined with periocular needle-embedding therapy can effectively prevent from true myopia, control the increase of SE, delay the growth of AL and improve AMP in children with pseudomyopia. This compound therapeutic regimen can relieve the general symptom and comprehensively prevent from myopia through multiple approaches, with high safety and satisfactory compliance.

Auricular Point Acupressure: A Complementary Medicine Treatment for Pain Management

Effects of adding acupuncture to group psychotherapy for anxiety

IntroductionAcupuncture has long been used in treating anxiety, and a literature exists on its effectiveness. However, acupuncture is rarely covered by government insurance (Medicaid or Medicare) or even by many commercial insurance carriers in the United States, making it inaccessible to those who cannot pay separately.ObjectivesWe asked if adding acupuncture to an anxiety group would improve outcome.Methods We provided acupuncture during group psychotherapy for anxiety as a non-billable service. This was feasible since patients were already being billed for group psychotherapy. A physician and a social work intern led the group. At the start of the group, the physician went around the circle of group members and inserted acupuncture needles, using points in the ears, head, hands, feet, and, in the summer, arms and lower legs). The size of the group ranged from 4 to 12 people. We used Battlefield auricular points, the four gates (Large Intestine 4 and Liver 3, bilaterally), and GV24, GV29, Ht7, and Sp6. Sometimes, other points were added for other symptoms (back pain, neck pain, etc.) People sometimes joined the group without anxiety as a core problem in getting access to acupuncture. A core group of patients formed who came weekly while others came and went. The Hamilton Anxiety Scale measured anxiety after treatments 4, 8, and 12. The group lasted 90 minutes and consisted of mindfulness training, guided imagery, and CBT for anxiety. All patients met the criteria for generalized anxiety disorder. The t-test procedure was used to compare the differences between the means for the two groups.Results Thirty-five patients received acupuncture, while another 55 patients attended the group and did not elect to receive acupuncture. All patients were covered by MaineCare health insurance, Maine’s version of Medicaid. All patients had multiple other medical problems, which was why they were referred to the group. Seventy percent of the patients were women, and 30% were men. The average age was 40.1 years. Anxiety ratings on the Hamilton Anxiety Scale decreased by the last time measured for those not receiving acupuncture by an average of 5.17 points (S.D. 2.9; n = 55). Anxiety ratings for those receiving acupuncture decreased by an average of 7.19 points (S.D. 2.5, n = 35). The difference of the means was -2.02 (S.E. 0.595; 95% CI = -2.203 to -0.837; t = -3.394; p = 0.001). Headaches, shoulder pains, and upper back pain also decreased. Patients reported high levels of benefit from the acupuncture and encouraged other patients to continue to come and try the acupuncture. Usually, the needles could be placed within the first third of the group.ConclusionsAcupuncture improved anxiety ratings for people in group psychotherapy for anxiety over group alone, though the possibility of a placebo effect cannot be eliminated. Patients chose acupuncture, which could also present a potential bias.Disclosure of InterestNone Declared

Clinical experience of professor ZHANG Ren in the staging treatment with characteristic acupuncture techniques for oculomotor paralysis.

The paper summarizes the clinical experience of professor ZHANG Ren in the staging treatment with characteristic acupuncture techniques for oculomotor paralysis. According to the symptoms of oculomotor paralysis, the staging treatment is given, in which acupuncture is dominant and the needling techniques are optioned in compliance with the symptoms. In the early, middle and late stages of illness, three different acupuncture therapies are delivered accordingly, i.e. the combination of the point-toward-point needling at the four acupoints located on the forehead and the electroacupuncture with disperse-dense wave, the surrounding needling and the triple needling at the acupoints around the eyeball, as well as the perpendicular needle insertion at the three acupoints within the orbit. Professor ZHANG Ren lays the stress on identifying the etiology and differentiating the symptoms, as well as the early intervention for the disease. For the intractable cases, the comprehensive regimen such as acupoint injection, dermal needling and auricular point sticking is supplemented. During treatment, the spirit harmonization is greatly considered to ensure the effectiveness. On the basis of the staging acupuncture therapy, the acupuncture technique for harmonizing the spirit and regulating qi is combined to obtain the favorable clinical effect on oculomotor paralysis.

Retention, adherence, and acceptability testing of a digital health intervention in a 3-group randomized controlled trial for chronic musculoskeletal pain

ObjectivesEvaluate a digital health intervention using Auricular Point Acupressure (APA) for chronic musculoskeletal pain in terms of participant retention, adherence, acceptability, and satisfaction. Chronic musculoskeletal pain is a global concern and there are persistent challenges in pain management. Despite the value of digital health interventions, these interventions need to be fully evaluated for feasibility. MethodsWe conducted a 3-group, longitudinal, randomized controlled trial (RCT). After Institutional Review Board approval, we posted recruitment flyers in a university, healthcare clinics, and community settings. Participants were randomized into an in-person + app group (n = 8), virtual + app group (n = 7), and a wait-list, education-enhanced control group (n = 8), evaluating our outcomes using standard feasibility measures. The 4-week intervention consisted of virtual sessions, telecommunications, and our APA app, followed by a 3-month follow-up. ResultsData from 22 participants were subsequently analyzed (95.7%). All app participants adhered to the study protocol and used APA at the minimum recommended frequency and duration. The virtual + app group used APA more during the intervention and follow-up periods. All app participants found the intervention to be acceptable and at least 80% overall were satisfied with APA at the 3-month follow-up. There were no adverse events reported. ConclusionsOur digital health intervention was found to be acceptable and sustainable; participants adhered to and were satisfied with the intervention providing support for a larger RCT.

Deep learning approach for automatic segmentation of auricular acupoint divisions

The automatic segmentation of auricular acupoint divisions is the basis for realizing intelligent auricular acupoint therapy. However, due to the large number of ear acupuncture areas and the lack of clear boundary, existing solutions face challenges in automatically segmenting auricular acupoints. Therefore, a fast and accurate automatic segmentation approach of auricular acupuncture divisions is needed. A deep learning-based approach for automatic segmentation of auricular acupoint divisions is proposed, which mainly includes three stages: ear contour detection, anatomical part segmentation and keypoints localization, and image post-processing. In the anatomical part segmentation and keypoints localization stages, K-YOLACT was proposed to improve operating efficiency. Experimental results showed that the proposed approach achieved automatic segmentation of 66 acupuncture points in the frontal image of the ear, and the segmentation effect was better than existing solutions. At the same time, the mean average precision (mAP) of the anatomical part segmentation of the K-YOLACT was 83.2%, mAP of keypoints localization was 98.1%, and the running speed was significantly improved. The implementation of this approach provides a reliable solution for the accurate segmentation of auricular point images, and provides strong technical support for the modern development of traditional Chinese medicine.
