Acupoint Embedding of Polyglactin 910 Sutures in Patients with Chronic Pain due to Cervical Spondylotic Radiculopathy: A Multicenter, Randomized, Controlled Clinical Trial

Eligibility Criteria of Participants in Randomized Controlled Trials Assessing Conservative Management of Cervical Radiculopathy: A Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVE

The aim of this study was to evaluate the inclusion and exclusion criteria for participants in randomized control trials (RCTs) assessing conservative management for cervical radiculopathy (CR), to determine if any consensus exists within the literature.

SUMMARY OF BACKGROUND DATA

A 2012 systematic review identified a lack of uniformity for the eligibility criteria of participants in RCTs evaluating conservative interventions for CR. Since then, a large number of RCTs have been published, signaling the need for an updated evaluation of this topic.

MATERIALS AND METHODS

We electronically searched MEDLINE, CENTRAL, CINAHL, Embase, and PsycINFO from inception to June 15, 2022, to identify RCTs assessing conservative management of CR. Information extracted was analyzed to determine the level of homogeneity and/or heterogeneity of the inclusion and exclusion criteria across studies.

RESULTS

Seventy-six RCTs met our inclusion criteria with 68 distinct trials identified. The inclusion of arm pain with or without another symptom ( i.e. numbness, paresthesia, or weakness) was required in 69.12% of trials, 50% of trials required participants to exhibit neck symptoms, and 73.53% of studies required some form of clinical examination findings, but inconsistencies existed for the number and type of tests used. Furthermore, 41.18% of trials included imaging, with 33.82% of trials requiring magnetic resonance imaging findings. The most common exclusion criteria included were the presence of red flags and cervical myelopathy in 66.18% and 58.82% of trials, respectively.

CONCLUSIONS

Overall, there is still a lack of uniformity for the inclusion/exclusion criteria of trials assessing the conservative management of CR, with some improvements noted compared with the 2012 review. Based on the current literature assessing the diagnostic utility of clinical symptoms and confirmatory tests, we proposed inclusion criteria for trials assessing conservative interventions. Future research should aim to develop standardized classification criteria to improve consistency among studies.

Conservative Management of Cervical Radiculopathy: A Systematic Review

OBJECTIVE

The purpose of this systematic review was to assess the effectiveness and safety of conservative interventions compared with other interventions, placebo/sham interventions, or no intervention on disability, pain, function, quality of life, and psychological impact in adults with cervical radiculopathy (CR).

METHODS

We searched MEDLINE, CENTRAL, CINAHL, Embase, and PsycINFO from inception to June 15, 2022 to identify studies that were randomized controlled trials, had at least one conservative treatment arm, and diagnosed participants with CR through confirmatory clinical examination and/or diagnostic tests. Studies were appraised using the Cochrane Risk of Bias 2 tool and the quality of the evidence was rated using the Grades of Recommendations, Assessment, Development, and Evaluation approach.

RESULTS

Of the 2561 records identified, 59 trials met our inclusion criteria (n = 4108 participants). Due to clinical and statistical heterogeneity, the findings were synthesized narratively. There is very-low certainty evidence supporting the use of acupuncture, prednisolone, cervical manipulation, and low-level laser therapy for pain and disability in the immediate to short-term, and thoracic manipulation and low-level laser therapy for improvements in cervical range of motion in the immediate term. There is low to very-low certainty evidence for multimodal interventions, providing inconclusive evidence for pain, disability, and range of motion. There is inconclusive evidence for pain reduction after conservative management compared with surgery, rated as very-low certainty.

DISCUSSION

There is a lack of high-quality evidence, limiting our ability to make any meaningful conclusions. As the number of people with CR is expected to increase, there is an urgent need for future research to help address these gaps.

Thread Embedded Acupuncture for Non-Specific Posterior Neck Pain: A PRISMA-Compliant Protocol for Systematic Review and Meta-Analysis

Purpose

The prevalence of non-specific posterior neck pain (NPNP) has been increasing yearly. There are several treatments for NPNP, but in this review, we will focus on thread-embedded acupuncture (TEA). TEA is used in the Republic of Korea, Taiwan, and China for managing musculoskeletal diseases, obesity, and sequelae of facial palsy. However, there is insufficient evidence on its effectiveness and safety. This study aims to assess the efficacy and safety of TEA for NPNP.

Methods

We will search the following nine electronic databases, from their inception to May 2020: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Citation Information by the National Information infrastructure, Korean Studies Information Service System, National Digital Science Library, Oriental Medicine Advanced Searching Integrated System, and Research Information Service System. Only randomized controlled trials of TEA for NPNP will be included. The methodological quality of the included trials will be assessed using the Cochrane risk-of bias tool. To conduct the meta-analysis, the risk ratio and mean difference with the 95% confidence interval will be used. Sensitivity analyses will be conducted based on this protocol.

Results

The results of this study will be submitted to a peer-reviewed journal for publication.

Conclusion

The results of this study would provide the evidence of whether TEA can be effective for treating NPNP.

Thunder-fire moxibustion for cervical spondylotic radiculopathy: Study protocol for a randomized controlled trial

BACKGROUND

Thunder-fire moxibustion originated in China and contains traditional Chinese medicine. It can produce strong firepower, infrared thermal radiation, and medicinal effects when burning on the acupoints. Thunder-fire moxibustion is commonly used in patients with neck pain, but its efficacy has rarely been systematically demonstrated. We designed a randomized trial of thunder-fire moxibustion on cervical spondylotic radiculopathy (CSR) to investigate whether it is more effective than ibuprofen sustained-release capsules.

METHODS

One hundred patients will be recruited and randomly divided into thunder-fire moxibustion and ibuprofen groups. The intervention consists of ten treatments and will last for 2 weeks. The Yasuhisa Tanaka 20 Score Scale is used as the primary outcome measure. It contains a combination of the self-conscious symptom in patients, objective clinical evaluation from doctors, and social evaluation (the ability to work and live). The objective and comprehensive evaluation of CSR patients before and after treatment is particularly needed. The Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2), Neck Disability Index score scale (NDI), and the Quality of Life Assessment (SF-36) are applied as secondary outcome measures. The assessment will take place at the baseline and the first and second weekends of treatment. If an adverse event (AEs) occurs, it will be reported.

DISCUSSION

The aim of this trial is to determine whether thunder-fire moxibustion is more effective than ibuprofen in the treatment of patients with CSR.
