Action of ear acupuncture in people with chronic pain in the spinal column: a randomized clinical trial1

A scoping review of mechanisms of auricular acupuncture for treatment of pain

OBJECTIVES

Auricular acupuncture (AA) is becoming increasingly common in primary care clinics, emergency departments and peri-operatively for pain relief. Over the last decade, since the last comprehensive reviews were published, the literature has expanded. In this scoping review, we seek to document the efficacy of AA in treating both acute and chronic pain, describe the mechanism of action of AA in treating pain, and discuss how AA has been integrated into Western medicine to date.

METHODS

The authors performed a MEDLINE search inclusive of articles from 1966 to June 2023 including articles written in English identifying literature. We included human studies when more than 3 patients were included. Three hundred and fourteen unique articles were identified and 152 were selected by title screen. After abstract review, 117 were chosen for full-text review. Following full-text review, 33 articles were excluded and 21 added from references, totaling 105 articles included in our scoping review.

RESULTS

AA reduces pain severity in patients with both acute and chronic pain. The best studies in the acute settings have occurred in the peri-operative setting where sham AA is employed, multiple sessions of AA are given, and medication dosing is carefully monitored. In these cases, AA reduced pain and post-operative medications. In patients with chronic pain, multiple sessions of AA resulted not only in pain relief but also in improvements in function and disability. Literature suggests that AA works through multiple mechanisms with the most compelling data coupled to the autonomic nervous system and neuroendocrine system. Curriculums designed to teach AA and aid in implementation have been published.

CONCLUSION

AA is an accessible, effective means of pain relief. AA is relatively straightforward to learn, and protocols and curriculums exist to teach healthcare professionals this valuable skill. Overcoming implementation barriers, including patient education, are essential next steps.

Laser auriculotherapy associated with cupping therapy in chronic spinal pain: Randomized controlled clinical trial

BACKGROUND

Musculoskeletal spine disorders are common causes of chronic pain and impair functionality. Laser auriculotherapy and cupping has played a significant role in the treatment of chronic pain.

OBJECTIVE

to evaluate the effect of laser auriculotherapy associated with cupping at systemic acupuncture points on chronic spinal pain.

METHODS

Randomized controlled clinical trial. Volunteers underwent three evaluations: an initial evaluation, a final evaluation immediately after the last intervention session, and a 15-day follow-up. The pain was identified using the numeric pain scale. The pain threshold was also evaluated against mechanical stimulation using a Digital Dynamometer at specific points in the cervical, thoracic and lumbar regions. Fifty individuals with chronic spinal pain, randomized into groups: experimental (n = 25), submitted to 10 sessions of auriculotherapy with laser and cupping therapy and control (n = 25).

RESULTS

The experimental group achieved pain intensity reduction between pre and post and follow-up moments (p < 0.0001), of greatest pain in the last seven days among all moments (p < 0.0001), of least pain in the pre with post moment (p = 0.006) and follow-up (p = 0.002), and an increased pain threshold between pre and post (p = 0.023). The control group achieved a reduction in the nociceptive threshold between pre and post (p = 0.001) and follow-up (p < 0.0001). The experimental group showed reduced pain intensity (p = 0.027) and greater pain (p = 0.005) after intervention and in pain intensity (p = 0.018), greater (p < 0.0001) and less pain (p = 0.025) at follow-up, compared to the control group.

CONCLUSION

Auriculotherapy with laser associated with cupping therapy may effectively reduce pain intensity and increase the nociceptive threshold.

PHYSICAL AND EMOTIONAL FACTORS ASSOCIATED WITH THE SEVERITY OF CHRONIC BACK PAIN IN ADULTS: A CROSS-SECTIONAL STUDY

ABSTRACT Objective: determining the multidimensional factors associated with the severity of chronic back pain is essential to design appropriate interventions. The objective of this study was to assess the physical and emotional factors associated with the severity of chronic back pain in adults. Method: a descriptive, analytical and cross-sectional study, carried out between November 2017 and December 2018 in Family Health Strategies, with 198 adults with chronic back pain. Pain severity, assessed by the Brief Pain Inventory, was considered the outcome variable; and the pain interference in daily activities (Brief Pain Inventory), physical disability (Roland Morris Disability Questionnaire), quality of life (World Health Organization Quality of Life-Brief) and pain threshold (digital algometer) variables were considered explanatory. A Multivariate Multiple Linear Regression analysis, using the stepwise method with 5% significance, was preformed to establish an explanatory model of pain severity. Results: the mean age was 48.03 years old (standard deviation: 12.41). Most of the participants were women, married and worked. The variables that had a significant and joint impact on pain severity were pain interference in daily activities (parameter: 0.196; p-value<0.001) and in mood (parameter: 0.054; p-value=0.039) and physical domain of quality of life (parameter: -0.032; p-value<0.001). Conclusion: physical factors (pain interference in daily activities and physical domain of quality of life) and emotional factors (pain interference in mood) play an important role in the severity of chronic back pain, which reinforces its multidimensional character.

Effects of ear acupuncture combined with cupping therapy on severity and threshold of chronic back pain and physical disability: A randomized clinical trial

Background and aim

Chronic back pain causes physical, functional, and emotional disabilities. Traditional Chinese Medicine therapies have been shown as interventions to treat chronic back pain. The present study aimed to clinically evaluate the effects of ear acupuncture combined with cupping therapy on people with chronic back pain.

Experimental procedure

We conducted an open-label, randomized, parallel-group controlled clinical trial. Following the CONSORT statement recommendations, 198 participants were randomized into ‘ear acupuncture’ and ‘ear acupuncture and cupping therapy’ groups. Data were collected in three different points; before the first session (initial) with the patient, after the last session (final), and seven days after the end of the treatment (follow-up). The Brief Pain Inventory, a digital algometer, and the Rolland Morris Disability Questionnaire were used for data collection. Generalized Estimation Equation model was used to examine the association between the interventions and the primary outcome pain severity.

Results

Pain severity, pressure pain threshold, and physical disability improved over time in both groups. However, for the patients being treated with both ear acupuncture and cupping therapy, significant changes were seen in pain severity, pain relief, and physical disabilities between the initial and final sessions. For the ‘ear acupuncture and cupping therapy’ group, significant changes were also seen for pain relief and physical disability in the follow-up session.

Conclusion

Ear acupuncture combined with cupping therapy was shown to be more effective in the treatment of chronic back pain when compared to treatment using only ear acupuncture.

•

Ear acupuncture plus cupping therapy is effective to treat chronic back pain.

•

Patients treated with both interventions achieved positive changes in all variables.

•

These are interventions that can be implemented in clinical practice.

Efeitos da auriculoterapia com sementes de mostarda na dor lombar crônica de profissionais de enfermagem

RESUMO Mais de 60% dos trabalhadores de enfermagem apresentam episódio de lombalgia durante um ano, provocando um impacto socioeconômico negativo, uma vez que é uma das maiores causas de faltas e afastamentos do trabalho. A auriculoterapia é uma técnica da acupuntura de baixo custo e não invasiva, que utiliza o pavilhão auricular como um microssistema do organismo humano mapeado por pontos que, estimulados, podem tratar diversas enfermidades. Sendo assim, o objetivo deste estudo foi verificar a eficácia da auriculoterapia com sementes de mostarda (Brassica juncea) na melhora da dor, na funcionalidade e na mobilidade lombar de profissionais técnicos e auxiliares de enfermagem do sexo feminino com dor lombar crônica. Foi realizado um ensaio clínico randomizado cego, dividido em dois grupos: um utilizou sementes de mostarda para acupressão nos pontos auriculares “Shen-Men”, “Rim”, “Simpático” e “Coluna Lombar” e o grupo placebo utilizou espuma de poliuretano de baixa densidade no lugar das sementes. Cada grupo realizou quatro sessões de auriculoterapia, uma vez por semana. Os grupos foram analisados por meio de termogramas infravermelhos e algometria por pressão para a dor, a medida dedo-chão para mobilidade e Questionário Roland-Morris para funcionalidade da coluna, com intervalo de confiança de 95%. A auriculoterapia com sementes de mostarda reduziu a temperatura média nos termogramas analisados em 0,8°C, bem como, aumentou o limiar de dor à pressão na coluna lombar das voluntárias em 0,4 Kgf, o que demonstra uma melhora significativa da dor lombar. Portanto, a auriculoterapia com sementes de mostarda mostrou-se eficaz na melhora da dor lombar.

Auriculotherapy and reducing chronic musculoskeletal pain: integrative review

OBJECTIVES

to describe the scientific evidence on the use of auriculotherapy to reduce chronic musculoskeletal pain in adults and the elderly.

METHODS

integrative literature review conducted in the Latin American and Caribbean Health Sciences, SciVerse Scopus and MEDLINE databases (via National Library of Medicine), in March 2019, with no time frame.

RESULTS

14 original scientific articles were analyzed, 64.3% of which were classified with level of evidence 2. All productions show the benefit of auriculotherapy in reducing chronic musculoskeletal pain, especially in the lumbar spine (42.9%). The treatment was developed in one or more sessions, using semi-permanent needles (42.9%) and electro-auriculotherapy (21.4%).

CONCLUSIONS

auriculotherapy was effective in reducing chronic musculoskeletal pain, showing itself as an alternative to be used for the promotion and recovery of individuals' health.

Using laser Doppler flowmetry with wavelet analysis to study skin blood flow regulations after cupping therapy

BACKGROUND

The purpose of this study was to use laser Doppler flowmetry (LDF) with wavelet analysis to investigate skin blood flow control mechanisms in response to various intensities of cupping therapy. To the best of our knowledge, this is the first study to assess skin blood flow control mechanism in response to cupping therapy using wavelet analysis of laser Doppler blood flow oscillations.

MATERIALS AND METHODS

Twelve healthy participants were recruited for this repeated-measures study. Three different intensities of cupping therapy were applied using 3 cup sizes at 35, 40, and 45 mm (in diameter) with 300 mm Hg negative pressure for 5 minutes. LDF was used to measure skin blood flow (SBF) on the triceps before and after cupping therapy. Wavelet analysis was used to analyze the blood flow oscillations (BFO) to assess blood flow control mechanisms.

RESULTS

The wavelet amplitudes of metabolic and cardiac controls after cupping therapy were higher than those before cupping therapy. For the metabolic control, the 45-mm cupping protocol (1.65 ± 0.09) was significantly higher than the 40-mm cupping protocol (1.40 ± 0.10, P < .05) and the 35-mm cupping protocol (1.35 ± 0.12, P < .05). No differences were showed in the cardiac control among the 35-mm (1.61 ± 0.20), 40-mm (1.64 ± 0.24), and 45-mm (1.27 ± 0.25) cupping protocols.

CONCLUSION

The metabolic and cardiac controls significantly contributed to the increase in SBF after cupping therapy. Different intensities of cupping therapy caused different responses within the metabolic control and not the cardiac control.

Auriculotherapy to control chemotherapy-induced nausea and vomiting in patients with cancer: protocol of a systematic review

BACKGROUND

Due to the worldwide rise in cancer incidence, and therefore the rise in the need for antineoplastic chemotherapy, it is important for both healthcare professionals and patients alike that the side effects of chemotherapy, such as chemotherapy-induced nausea and vomiting (CINV), are treated and prevented. Auriculotherapy is a type of acupuncture and may be a low-cost and safe antiemetic measure to control the side effects of chemotherapy. The goal of this systematic review is to synthesize the available evidence in the literature regarding the auriculotherapy effects to treat CINV in people with cancer.

METHODS

The review will only include randomized controlled trials (RCTs) that compare the clinical effects of the auriculotherapy intervention (used alone or as an add-on), with sham auriculotherapy, routine treatment with antiemetic drugs, or other non-pharmacological interventions in patients with cancer with CINV who are undergoing chemotherapy. The outcomes to be evaluated are nausea and vomiting: in acute, delayed, or anticipated stages, when induced by chemotherapy. A comprehensive search for studies will be carried out in these databases: MEDLINE via PubMed, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, ICTRP, LILACS, CUMED, IBECS, BVS MTCI Americas, Web of Science, Scopus, PEDro, CNKI, and CBMdisc up until December 31, 2018. Only articles in English, Portuguese, and Spanish will be selected. Two independent reviewers will evaluate full texts, extract data, and assess the risk of bias of eligible articles. The quality of evidence will be assessed using Grading of Recommendations, Assessment, Development and Evaluation (GRADE). A meta-analysis will be undertaken to assess the interventions and outcomes' homogeneity, assessing statistical heterogeneity using the Cochran's Q test and quantified using Higgins' inconsistency index. If there is insufficient data for a meta-analysis, a narrative synthesis will be presented. This protocol has been prepared according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines.

DISCUSSION

The results of this systematic review will summarize the strength of evidence for the use of auriculotherapy in the control of CINV of patients with cancer and will be used to identify evidence gaps.

Contribution of Chinese and French ear acupuncture for the management of chronic back pain: A randomised controlled trial

AIMS AND OBJECTIVES

To compare the efficacy of Chinese and French ear acupuncture in people with chronic back pain.

BACKGROUND

Chronic back pain is a common public health problem worldwide. An intervention for this condition is ear acupuncture. Several approaches are used for ear acupuncture, particularly the Chinese and French guidelines.

METHODS

An open, randomised and controlled clinical trial, followed the recommendations of the CONSORT Checklist. One hundred and eleven people were selected and randomised into three groups: Chinese ear acupuncture, French ear acupuncture and Control. Evaluations were performed before the first intervention session (initial), 1 week after the fifth session (final) and after a fifteen-day follow-up period (follow-up), using the Brief Pain Inventory, Rolland Morris Disability Questionnaire, and a thermal imaging camera. For data analysis, the Generalized Estimating Equation Model was applied, with significance level set at 5%.

RESULTS

Pain severity was significantly decreased by Chinese ear acupuncture throughout intervention period. Both types of ear acupuncture affected pain interference with daily activities. However, in the comparison between initial and final evaluations, only Chinese ear acupuncture produced statistically significant results. A reduction in physical disability was observed in both ear acupuncture-treated groups during the intervention period and, although Chinese ear acupuncture failed to induce significant changes in tissular temperature at individual time points, a significant increase in cutaneous temperature was detected after the follow-up period in the dorsal region of individuals treated with Chinese ear acupuncture. Importantly, at this time point, the mean difference between Chinese and French ear acupuncture revealed a more benefic effect of Chinese procedure on this parameter.

CONCLUSIONS

The individualised treatment based on the Chinese precepts showed, in an overall evaluation, better results for management of chronic back pain in the present study.

RELEVANCE TO CLINICAL PRACTICE

Ear acupuncture can be implemented in the nurse's clinical practice to assist the treatment of people with chronic back pain.

Acupuncture in adults with Chemotherapy-Induced Peripheral Neuropathy: a systematic review

Objective:

to analyze and synthesize knowledge about the effect of acupuncture on chemotherapy-induced peripheral neuropathy symptoms in adults with cancer.

Method:

the method used was a Systematic Review. Potential articles were identified by searching in the PubMed of National Library of Medicine, Cumulative Index to Nursing and Allied Health Literature, Embase, Cochrane Central and Scopus. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy, 607 articles were identified. After removing the duplicates, all titles and abstracts were reviewed, and seven articles were selected for full review. After the full review, five studies were selected for inclusion.

Results:

of the five articles included, four were cohort studies and one was a quasi-experimental study. All articles showed that acupuncture was associated with an improvement in the peripheral neuropathy, but the type of protocol, use of medications, time of treatment, and different outcome measures made it difficult to compare the studies.

Conclusion:

the use of acupuncture appears to be associated with an improvement in the symptoms of chemotherapy-induced peripheral neuropathy and has no side effects. In order to improve the evidence about benefits associated with acupuncture, more experimental studies using both subjective and objective measures are needed.
