Acupuncture for lateral epicondylitis (tennis elbow): study protocol for a randomized, practitioner-assessor blinded, controlled pilot clinical trial

Efficacy and safety of electroacupuncture for oxaliplatin-induced peripheral neuropathy in colorectal cancer patients: a single-blinded, randomized, sham-controlled trial

BACKGROUND

Oxaliplatin-based chemotherapy is a major first-line conventional therapy for advanced and metastatic colorectal cancer (CRC). However, oxaliplatin causes chemotherapy-induced peripheral neuropathy (CIPN). Acupuncture has long been used to alleviate limb numbness in Chinese medicine practice.

AIM

The aim of this study was to examine the efficacy and safety of electroacupuncture (EA) for the alleviation of CIPN in CRC patients.

DESIGN

This was a pilot single-blinded, randomized, sham-controlled trial.

SETTING/PARTICIPANTS

Sixty eligible patients, who had been diagnosed with CRC and were undergoing oxaliplatin-based chemotherapy, were randomized in a ratio of 1:1 to the EA intervention group or sham acupuncture (SA) control group. During a 12-week treatment period, patients in the EA group received EA once a week, while patients in the SA group received SA; both groups were followed up for 12 weeks.

RESULTS

Compared with the SA group, the EA group exhibited significant alleviation of CIPN severity during chemotherapy. Moreover, EA also improved the physical function, role function, and social function of CRC patients. However, there were no significant differences in tests of vibration or light touch sensation. In addition, EA appeared to be a safe treatment for CIPN and was both feasible and acceptable to CRC patients during chemotherapy.

CONCLUSION

This study showed preliminary evidence for the efficacy and safety of EA in acute CIPN among CRC patients, although further studies are needed to verify these effects and to further explore the potential role of EA in chronic CIPN (effects on which remain unclear).

Suggesting a mechanism for acupuncture as a global percutaneous needle fasciotomy that respects tensegrity principles for treating fibromyalgia

Acupuncture is a minimally invasive therapeutic method that uses small caliber needles while inserting them through the skin into various areas of the body. Some empirical studies find evidence to support the use of acupuncture as a treatment for certain medical conditions, however, this peculiar practice is widely considered as the domain of alternative and non-evidence-based medicine. Several mechanisms have been suggested in an attempt to explain the therapeutic action of acupuncture, but the way in which acupuncture alleviates chronic non-cancer pain or psychosomatic and psychiatric disorders is not fully understood. A recent study suggested a theoretical model (coined "Fascial Armoring") with a cellular pathway to help explain the pathogenesis of myofascial pain/fibromyalgia syndrome and functional psychosomatic syndromes. It proposes that these syndromes are a spectrum of a single medical entity that involves myofibroblasts with contractile activity in fascia and aberrant extracellular matrix (ECM) remodeling, which may lead to widespread mechanical tension and compression. This can help explain diverse psycho-somatic manifestations of fibromyalgia-like syndromes. Fascia is a continuous interconnected tissue network that extends throughout the body and has qualities of bio-tensegrity. Previous studies show that a mechanical action by needling induces soft tissue changes and lowers the shear modulus and stiffness in myofascial tissue. This hypothesis and theory paper offers a new mechanism for acupuncture therapy as a global percutaneous needle fasciotomy that respects tensegrity principles (tensegrity-based needling), in light of the theoretical model of "Fascial Armoring." The translation of this model to other medical conditions carries potential to advance therapies. These days opioid overuse and over-prescription are ubiquitous, as well as chronic pain and suffering.

Healthcare Utilization for Lateral Epicondylitis: A 9-Year Analysis of the 2010–2018 Health Insurance Review and Assessment Service National Patient Sample Data

This retrospective cross-sectional study examined healthcare utilization among 213,025 patients with lateral epicondylitis over a nine-year period using the 2010–2018 Health Insurance Review and Assessment Service (HIRA) data (ICD code M771). Healthcare utilization, types of treatment, and the route of the visit were analyzed with frequency analysis for Western medicine (WM) and Korean medicine (KM). The findings revealed that the number of patients visiting WM and KM facilities for lateral epicondylitis rose every year from 2010 to 2018. Over this period, the age distribution of patients was 45–54 years (39.93%), 55–64 (23.12%), and 35–44 years (21.07%), and there were slightly more female patients (53.66%) than male patients (46.34%). The number of claims for lateral epicondylitis tended to increase with decreasing average monthly temperature; an increased proportion of middle-aged patients (45–64 years) was the most evident. The most frequently performed interventions in WM were subcutaneous or intramuscular injection (injection), deep heat therapy (physical therapy), and spinal peripheral nerve block-axillary nerve block (treatment/operation); the most frequently performed intervention in KM was acupuncture (injection). For pharmacological treatment, analgesics and anti-inflammatory medications were most frequently prescribed. The findings can be useful for health policymakers and as foundational data for clinicians and researchers.

Efficacy of ultrasound therapy for the treatment of lateral elbow tendinopathy (the UCICLET Trial): study protocol for a three-arm, prospective, multicentre, randomised controlled trial

INTRODUCTION

Lateral elbow tendinopathy (LET) is a highly prevalent disease among the middle-aged population, with no consensus on optimal management. Non-operative treatment is generally accepted as the first-line intervention. Ultrasound (US) therapy has been reported to be beneficial for various orthopaedic diseases, including tendinopathy. The purpose of this study is to investigate the efficacy of US for LET treatment.

METHODS AND ANALYSIS

This protocol entails a three-arm, prospective, multicentre, randomised controlled trial. Seventy-two eligible participants with clinically confirmed LET will be assigned to either (1) US, (2) corticosteroid injections or (3) control group. All participants will receive exercise-based therapy as a fundamental intervention. The primary outcome is Patient-rated Tennis Elbow Evaluation. The secondary outcomes include Visual Analogue Scale for pain, shortened version of the Disabilities of the Arm, Shoulder and Hand for upper limb disability, pain free/maximum grip strength, Work Limitations Questionnaire-25 for functional limitations at work, EuroQol-5D for general health, Hospital Anxiety and Depression Scale for mental status, Global Rating of Change for treatment success and recurrence rate, and Mahomed Scale for the participant's satisfaction. Adverse events will be recorded. Intention-to-treat analyses will be used.

ETHICS AND DISSEMINATION

Ethics committees of all clinical centres have approved this study. The leading centre is Shanghai Sixth People's Hospital, whose approval number is 2021-153. New versions with appropriate amendments will be submitted to the committee for further approval. Final results will be published in peer-reviewed journals and presented at local, national and international conferences.

Immediate Effects of Acupuncture on Force and Delayed Onset of Muscle Soreness

Background: The ability to produce force is critical to several daily activities. Strategies to reduce delayed onsent muscle soreness (DOMS) and restore force-generating properties that occur in response to training and impair physical performance have been proposed. Acupuncture has been proposed to accelerate recovery and optimize muscle functioning. It was to determine the effects of acupuncture on DOMS and on the muscle force production capacity. Methods: Thirty physically active volunteers (26.3 ± 3.1 years old, 1.70 ± 0.08 m, 66.5 ± 12.6 kg) were allocated in a control (CG; n = 10), placebo (PG; n = 10), and acupuncture (AG; n = 10) groups. The groups were subjected to an exercise protocol to induce DOMS and were assessed for muscle force, threshold, and rate of perceived pain and activation of the biceps brachialis muscle before (PRE) and 20 minutes after (POST) a single acupuncture session using a mixed model analysis. Results: The threshold and rate of perceived pain were reduced in the AG (P < 0.05) but remained unchanged in the other groups (P > 0.05). Muscle activation also showed larger changes in the AG in comparison with the other groups (P < 0.05). No changes in the ability to produce force were found after acupuncture in any groups (P > 0.05). Conclusions: Acupuncture may reduce discomfort and improve muscle activation but was not effective to promote force improvement and/or restore the force-generating properties. It may be speculated that muscle disruption may have played a role and did not allow participants to restore their muscular performance.

Effects of manual acupuncture and electroacupuncture for lateral epicondylalgia of musculoskeletal origin: a systematic review and meta-analysis

OBJECTIVE

The aim of this study was to evaluate the effect of acupuncture/electroacupuncture, alone or combined with other interventions, on pain intensity, pain-related disability, and strength in lateral epicondylalgia (LE) of musculoskeletal origin.

DATABASES AND DATA TREATMENT

Electronic databases were searched for randomized clinical trials, where at least one group received acupuncture or electroacupuncture for LE of musculoskeletal origin. To be eligible, trials had to include humans and collect outcomes on pain intensity or pain-related disability in LE. Data were extracted by two reviewers. The risk of bias (RoB) of the trials was assessed using the Cochrane RoB tool, methodological quality was assessed with the Physiotherapy Evidence Database (PEDro) score, and the level of evidence was summarized using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Standardized mean differences (SMDs) using random effects were calculated.

RESULTS

A total of 14 trials (10 acupuncture) were included. The meta-analysis found a moderate effect size of acupuncture (SMD = -0.66, 95% confidence interval (CI) = -1.22 to -0.10), but not electroacupuncture (SMD = -0.08, 95% CI = -0.99 to 0.83), in the reduction of elbow pain as compared to a comparative group. Acupuncture exhibited a significant moderate effect size (SMD = -0.51, 95% CI = -0.91 to -0.11) in the improvement of related-disability. Acupuncture (SMD = 0.36, 95% CI = 0.16 to 0.57), but not electroacupuncture (SMD = 0.34, 95% CI = -0.29 to 0.98), exhibited a significant but small effect size on strength. Most significant effects were in the short term. The RoB was low but the heterogeneity of trial results led to a downgrading of the GRADE evidence level.

CONCLUSION

Low-level evidence suggests positive effects of acupuncture, but not electroacupuncture, for pain, related-disability, and strength, in LE of musculoskeletal origin, in the short term.

The efficacy and safety of electro-acupuncture for alleviating chemotherapy-induced peripheral neuropathy in patients with coloreactal cancer: study protocol for a single-blinded, randomized sham-controlled trial

Background

Colorectal cancer is the most common cancer in Hong Kong. Oxaliplatin-based chemotherapy is a major first-line conventional therapy for advanced and metastatic colorectal cancer. However, oxaliplatin causes chemotherapy-induced peripheral neuropathy (CIPN). Acupuncture has long been used to alleviate limb numbness in Chinese medicine. This study aims to examine the efficacy and safety of acupuncture for alleviating CIPN in patients with colorectal cancer in Hong Kong.

Methods/design

This is a single-blinded, randomized, sham-controlled efficacy trial. Eighty-four eligible patients, who are Hong Kong Chinese, aged ≥ 18 years, diagnosed with colorectal cancer and undergoing oxaliplatin-based chemotherapy, will be randomized in a ratio of 1:1 to the electro-acupuncture group or the sham-controlled group. During a 12-week treatment period, patients in the electro-acupuncture group will undergo electro-acupuncture once a week from the first cycle of chemotherapy, while patients in the control group will receive sham acupuncture, and the patients in both groups will be followed up for 12 weeks. The primary outcome measure is the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOC-Ntx) questionnaire. The secondary outcome measures include numerical rating scale (NRS) for numbness/pain, vibration and light touch sense test, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) and Constitution of Chinese Medicine Questionnaire (CCMQ).

Discussion

The study will compare electro-acupuncture with sham acupuncture to explore the feasibility for electro-acupuncture in improving symptoms caused by chemotherapy-induced peripheral neuropathy.

Effect of extracorporeal shock wave for tennis elbow: A protocol for systematic review of randomized controlled trial

BACKGROUND

Previous clinical studies have reported that extracorporeal shock wave (EPSW) is an effective treatment for patients with tennis elbow (TE). However, no systematic review has assessed its effectiveness and safety for the treatment of TE.

METHODS

In this systematic review, we will search the potential eligible literature from the following electronic databases: Central, Embase, MEDLINE, CINAHL, and CNKI from inception to the present. All literatures of randomized controlled trials of EPSW for TE will be considered without language restrictions. Two reviewers will independently select the studies, extract the data, and evaluate the methodology quality. All disagreements between those 2 reviewers will be resolved by a third reviewer involved through discussion. Outcome data will be pooled by RevMan 5.3 software if the heterogeneity is reasonable. Reporting bias will also be conducted if more than 10 included studies can be reached.

RESULTS

This systematic review will evaluate the clinical effectiveness and safety of EPSW for TE.

CONCLUSION

The findings of this study will summarize the current evidence of EPSW on TE outcomes and may provide guidance for both clinical practice and further studies.

DISSEMINATION AND ETHICS

This systematic review does not need ethical approval, because it does not utilize the individual patient data. Its findings are expected to publish in peer-reviewed journals.

The combination effects of body acupuncture and auricular acupressure compared to sham acupuncture for body weight control: study protocol for a randomized controlled trial

BACKGROUND

Obesity is an increasingly prevalent chronic condition that is associated with serious morbidity and mortality. Excess body weight is a risk factor contributing to diseases such as hypertension, heart disease, hypercholesterolaemia, diabetes mellitus, cerebrovascular disease, gall bladder disease, and some types of cancer. Almost all the Western anti-obesity drugs have adverse effects or body weight is regained upon cessation of therapy. Recent studies have found that acupuncture had a similar efficacy as the Western anti-obesity drugs with fewer reported adverse effects. However, these conclusions were limited due to the small sample size and low quality of methodologies of these studies. Therefore, we design this study to explore the effectiveness and safety of acupuncture on weight control.

METHODS/DESIGN

This is a pilot single-blinded, randomized, sham-controlled trial on acupuncture for body weight control. Seventy-two participants are randomly assigned to the acupuncture group or the control group. Tianshu (ST-25), Daheng (SP-15), Daimai (GB-26), Qihai (CV-6), Zhongwan (CV-12), Zusanli (ST-36), Fenglong (ST-40), and Sanyinjiao (SP-6) are selected as acupuncture points. For the acupuncture group, disposable acupuncture needles will be inserted at a depth of 10-25 mm into the points and electrical stimulation with dense-disperse waves at 50 Hz and 10 V will be applied on the abdominal points. The bodily needles will be retained for 30 minutes. For subjects assigned to the control group, Streitberger's non-invasive acupuncture needles will be applied to serve as the sham control at the same acupoints with the same stimulation modality, except that the needles are only adhered to the skin instead of inserted. The duration of the treatment is 8 weeks with two sessions per week, and the follow-up period is 8 weeks. The primary outcome is the change in body weight before and after treatment. The secondary outcomes include changes in body mass index, waist circumference, hip circumference, and body fat percentage during the treatment and follow-up period.

DISCUSSION

The study will compare the efficacy and safety of acupuncture with sham acupuncture on weight control, in the hope of obtaining evidence for utilizing acupuncture for body weight control.

Acupuncture for Lateral Epicondylitis: A Systematic Review

Objective. This systematic review aimed to assess the effectiveness and safety of acupuncture for lateral epicondylitis (LE). Methods. Seven databases and the WHO International Clinical Trials Registry Platform Search Portal were searched to identify relevant studies. The data were extracted and assessed by two independent authors, and Review Manager Software (V.5.3) was used for data synthesis with effect estimate presented as standard mean difference (SMD) and mean difference (MD) with a 95% confidence interval. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess the level of evidence. Results. Four RCTs with 309 participants were included with poor methodological quality. Participants who received acupuncture and acupuncture plus moxibustion with material insulation were likely to have an improvement in elbow functional status and/or myodynamia. The overall quality rated by GRADE was from very low to low. Two studies reported that the needle pain would be the main reason for the dropout. Conclusion. For the small number of included studies with poor methodological quality, no firm conclusion can be drawn regarding the effect of acupuncture of elbow functional status and myodynamia for LE. This trial is registered with CRD42015016199.

Analgesic Effect of Manual Acupuncture and Laser Acupuncture for Lateral Epicondylalgia: A Systematic Review and Meta-Analysis

Lateral epicondylalgia is a common orthopedic disorder. In traditional Chinese medicine, acupuncture is often used for treating lateral epicondylalgia. Laser acupuncture, compared with manual acupuncture, has more advantages because it is painless, aseptic and safe. However, the analgesic effect of manual acupuncture and laser acupuncture on lateral epicondylalgia has rarely been explored. We conducted a systematic review and meta-analysis to compare the analgesic effect of laser acupuncture and manual acupuncture for the treatment of lateral epicondylalgia. We investigated studies published in the Medline, PubMed, and CINAHL databases from January 1980 to December 2013. This review included 9 randomized articles. Six of them examined manual acupuncture and the others focused on laser acupuncture. We analyzed the meta-analysis results regarding the analgesic effect of the treatment, and observed substantial differences in 4 articles related to manual acupuncture. Manual acupuncture is effective in short-term pain relief for the treatment of lateral epicondylalgia; however, its long-term analgesic effect is unremarkable. A suitable acupuncture point and depth can be used to treat lateral epicondylalgia. Manual acupuncture applied on lateral epicondylalgia produced stronger evidence of an analgesic effect than did laser acupuncture, and further study on the analgesic effect of laser acupuncture is required.

Força de preensão manual em atletas de judô

INTRODUÇÃO: A força de preensão manual é a capacidade da mão em realizar tarefas, imprimir forças e segurar objetos. Dentre os diversos esportes que utilizam a força de preensão manual com predominância em sua prática, um deles é o judô, aonde a força de preensão manual é imprescindível para que o judoca consiga se impor ao adversário, pois está ligada à capacidade de realização do golpe. O objetivo deste estudo foi avaliar a força de preensão manual em atletas de judô.MÉTODOS: O estudo contou com a participação de 30 judocas, sendo formado por 15 faixas brancas e 15 faixas pretas, que foram submetidos a uma avaliação da força de preensão com um dinamômetro manual da marca Jamar(r). Foi utilizada a estatística descritiva (média e desvio-padrão) para análise dos dados antropométricos, o teste tde Student para verificação da homogeneidade entre os grupos e o Teste de Shapiro-Wilk para verificação da distribuição. Para análise de comparação intra e intergrupos foi utilizado o Teste de Mann-Whitney para amostras independentes (p≤0,05). Os dados foram analisados através do software BioEstat 5.0.RESULTADOS: Os resultados demonstraram que os judocas faixas pretas apresentam uma força de preensão palmar significativamente maior na mão dominante em relação à não dominante, e também significativamente maior em relação aos atletas de faixas brancas tanto na mão dominante quanto na mão não dominante.CONCLUSÃO: Atletas de judô faixas pretas têm preensão manual mais forte do que os atletas de faixas brancas, sugerindo que quanto maior o tempo de prática esportiva na modalidade, maior a força de preensão manual em ambas as mãos.
