Warm needle acupuncture in primary osteoporosis management: a systematic review and meta-analysis

Efficacy of acupuncture for primary osteoporosis: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Primary osteoporosis (POP) is a common metabolic bone disorder that has a devastating effect on their quality of life in patients. Acupuncture, a traditional Chinese therapy, has been used to treat osteoporosis for over 2000 years. This study aimed to determine the efficacy of acupuncture in treating POP compared to conventional medicine or placebo.

METHODS

We searched for potentially relevant studies in PubMed, Web of Science, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, China Biology Medicine disc, Wanfang database and ClinicalTrials.gov up to December 20, 2024. Randomized controlled trials investigating treatment of POP for which acupuncture was administered as a stand-alone treatment or combined with conventional medicine compared to conventional medicine or placebo, were included. The outcomes included bone mineral density (BMD), visual analogue scale (VAS) scores, clinical effectiveness rate, estradiol (E2), Oswestry Disability Index (ODI), and levels of serum alkaline phosphatase (ALP). Data were synthesized using a random-effects meta-analysis model, and the observed heterogeneity was investigated using subgroup analyses. Study quality was appraised using the Cochrane RoB 2 tools, and the quality of the aggregated evidence was evaluated using the GRADE guidelines. Publication bias was assessed by funnel plots and validated by Egger's test.

RESULTS

Forty eligible articles with 2654 participants were identified. Compared to the control group, acupuncture effectively increased the BMD (MD 0.04 [0.03-0.06], P < 0.001, I2 = 92%), clinical efficacy (RR 1.24 [1.14-1.34], P < 0.001, I2 = 81%), and levels of E2 (SMD 0.30 [0.09-0.52], P = 0.006, I2 = 0%), and reduced the VAS scores (SMD - 1.79 [- 2.29 to - 1.29], P < 0.001, I2 = 95%). Data on ODI and ALP were insufficient for meta-analysis.

CONCLUSION

The current evidence suggests that the efficacy of acupuncture in improving the symptoms of POP are encouraging for its use in clinical practice as a physical intervention for patients with POP. However, since the included patients were all from China, there was a risk of sample bias, high-quality multicenter studies in different countries or regions should be conducted in the future.

Efficacy and safety of warm needle acupuncture for allergic rhinitis: A systematic review and meta-analysis with trial sequential analysis

Backgrounds

Warm needle acupuncture is a distinct form of acupuncture therapy in which, after the needle is inserted into the acupoint, a lit moxa stick is placed on the needle's handle.

Objective

This research aims to provide evidence for efficacy and safety of warm needle acupuncture for allergic rhinitis.

Search strategies

Seven online databases were searched for study collection, which were published up to March 15th, 2022. Keywords of searching included "AR", "allergic rhinitis", "anaphylactic rhinitis", "warming needle", "warming needle acupuncture", "needle warming moxibustion", "warm needle", "warm needling method" and "warmed needle". The quality of the included trials was assessed using the Cochrane risk of bias tool.

Interventions

Among the included trials, warm needle acupuncture-either alone or in combination with Western medicine or other acupoint-based therapies-served as the primary intervention for the experimental groups. In contrast, the control groups received treatments such as Western medicine alone, manual acupuncture alone, or a combination of electro and manual acupuncture. Systematic reviews and meta-analyses were conducted using RevMan 5.3, following the Cochrane systematic review methodology, while trial sequential analysis was performed with TSA 0.9. The quality of the findings was assessed using GRADEpro.

Results

Finally, 23 studies involving 2230 participants were covered. Results of this study revealed that warm needle acupuncture only, or with western medicine, or with other acupoint-based interventions were significantly superior to western medicine alone, manual acupuncture alone, or electro plus manual acupuncture for allergic rhinitis. Adverse events associated with warm needle acupuncture included sensations of chest tightness, throat itching, and allergic reactions to moxa smoke; however, these occurrences were not more frequent than those observed with Western medicine. There is need for RCTs of high quality with placebo or waitlist controls of the intervention for allergic rhinitis.

Conclusion

Warm needle acupuncture is with potential efficacy and is safe for patients with allergic rhinitis, but more trials are need for further confirmation of the evidence.

Warming acupuncture-moxibustion combined with Bushen Qianggu Recipe effectively improves bone metabolism in osteoporosis patients

BACKGROUND

Osteoporosis (OP) increases the risk of fractures in older adults, with no effective treatment options at present.

OBJECTIVES

To analyze the effects of warming acupuncture-moxibustion (WAM) combined with Bushen Qianggu Recipe on bone metabolism, bone mineral density (BMD), and pain intensity in OP patients.

METHODS

This retrospective study involved 103 patients with OP who were admitted to Wuhan Hospital of Traditional Chinese Medicine between July 2021 and December 2023. The control group consisted of 47 cases given WAM and the research group consisted of 56 cases receiving WAM + Bushen Qianggu Recipe (Rehmanniae Radix 15 g, Radix Rehmanniae Preparata 15 g, Poria cocos 10 g, yam 10 g, rhizoma alismatis 10 g, raspberry 10 g, medlar 10 g, Schisandra chinensis 10 g, Semen Cuscutae 10 g, Epimedium 10 g, Polygonatum sibiricum Red. 10 g, Drynaria 10 g, and Eucommia ulmoides 10 g). Bone metabolism markers (procollagen type I N-terminal propeptide (PINP) and bone-specific alkaline phosphatase (B-ALP)), BMD (lumbar vertebrae at L2-4, femoral neck, and distal 1/3 of the radius), pain intensity (visual analog score (VAS)), dysfunction (Oswestry Dysfunction Index), quality of life (Short-Form 36 Item Health Survey (SF-36)), and overall treatment efficacy were analyzed comparatively.

RESULTS

Compared with the baseline (before treatment) and post-treatment levels in the control group, the research group showed a reduction in PINP and B-ALP, an increase in BMD at the lumbar vertebrae L2-4, femoral neck, and distal 1/3 of the radius, and a decrease in VAS and Oswestry Disability Index scores. Additionally, the research group performed better across various dimensions of the SF-36 scale and had a higher overall effective rate.

CONCLUSIONS

WAM combined with Bushen Qianggu Recipe is effective in alleviating pain intensity and improving bone metabolism, BMD, and quality of life in OP patients; therefore it is deserving of clinical promotion.

Attenuation of immobilization stress-induced hypertension by temperature-controllable warm needle acupuncture in rats and the peripheral neural mechanisms

Introduction

We and others have shown that electrical stimulation of the PC-6 acupoint over the wrist relieves hypertension by stimulating afferent sensory nerve fibers and activating the central endogenous opioid system. Warm needle acupuncture has long been utilized to treat various diseases in clinics.

Methods

Here, we developed a temperature-controllable warm needle acupuncture instrument (WAI) and investigated the peripheral mechanism underlying the effect of warm needle acupuncture at PC-6 on hypertension in a rat model of immobilization stress-induced hypertension.

Results

Stimulation with our newly developed WAI and traditional warm needle acupuncture attenuated hypertension development. Such effects were reproduced by capsaicin (a TRPV1 agonist) injection into PC-6 or WAI stimulation at 48°C. In contrast, PC-6 pretreatment with the TRPV1 antagonist capsazepine blocked the antihypertensive effect of WAI stimulation at PC-6. WAI stimulation at PC-6 increased the number of dorsal root ganglia double-stained with TRPV1 and CGRP. QX-314 and capsaicin perineural injection into the median nerve for chemical ablation of small afferent nerve fibers (C-fibers) prevented the antihypertensive effect of WAI stimulation at PC-6. Additionally, PC-6 pretreatment with RTX ablated the antihypertensive effect of WAI stimulation.

Conclusion

These findings suggest that warm needle acupuncture at PC-6 activates C-fiber of median nerve and the peripheral TRPV1 receptors to attenuate the development of immobilization stress-induced hypertension in rats.

Effect of laser acupuncture on pain and density of bone in osteoporotic postmenopausal women: a randomized controlled trial

OBJECTIVE

This study aimed to evaluate the value of laser acupuncture (LA) on forearm bone mineral density (BMD) and wrist pain in osteoporotic postmenopausal women.

METHODS

Sixty-eight postmenopausal women diagnosed with osteoporosis were randomly allocated equally to one of two sets. The drug-only group received calcium and vitamin D 3 supplement containing fluoride daily for 12 weeks, whereas the drug/LA group received LA therapy for 20 minutes per session, three sessions weekly, in addition to the same supplementation. The primary outcome parameter was assessment of BMD of the nondominant arm. Other outcomes included wrist pain.

RESULTS

There was a highly significant improvement in the T-score of forearm BMD in both groups (-2.844 ± 0.476 to -2.597 ± 0.478 and -2.944 ± 0.486 to -1.652 ± 0.728 in the drug-only and drug/LA groups, respectively; P < 0.0001) and visual analog scale score (7.50 ± 0.79 to 4.24 ± 1.07 and 7.24 ± 0.82 to 3.09 ± 0.75 in the drug-only and drug/LA group, respectively; P < 0.0001). The improvement of both BMD and pain score was significantly higher in the drug/LA group (-1.303 and 4.15) compared with the drug-only group (-0.247 and 3.26; P < 0.0001).

CONCLUSIONS

LA in combination with calcium and vitamin D supplementation containing fluoride is an effective modality in improving forearm BMD and reducing pain in osteoporotic postmenopausal women.

Overall adjustment acupuncture improves osteoporosis and exerts an endocrine-modulating effect in ovariectomized rats

BACKGROUND

Acupuncture is a widely practiced, convenient, and safe treatment modality within complementary and integrative medicine. Increasing studies have revealed the efficacy of acupuncture for the treatment of osteoporosis in both human and non-human subjects. The aim of the present study was to assess the improvement of osteoporosis after overall adjustment acupuncture (OA) as well as its endocrine-modulating effect in an ovariectomized rat model.

METHODS

In total, 32 female Sprague-Dawley (SD) rats were randomly divided into the sham, model, ovariectomy+estrogen (OVX+E), and OVX+OA (OVX+A) groups with eight rats in each group. The postmenopausal osteoporosis (PMOP) rat model was induced by bilateral ovariectomy. At 12 weeks after surgery, rats in the OVX+E group received estradiol (0.2 mg/kg/i.g./qod) for 12 weeks, and rats in the OVX+A group were treated with acupuncture at Zusanli (ST36), Shenshu (BL23), and Dazhu (BL11) points (qod) for 12 weeks. At the end of the treatment, all rats were sacrificed, and the body weight, uterus index, bone mineral density (BMD), bone mineral content (BMC), bone trabeculae structural parameters, femoral biomechanical properties, femoral histomorphology, and several hormone levels were examined.

RESULTS

In OVX rats, OA abrogated the body weight gain and improved osteoporosis in terms of BMD, BMC, bone trabeculae structural parameters, bone strength, and bone tissue histomorphology. Moreover, OA modulated the serum levels of estradiol, corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT).

CONCLUSIONS

OA improves osteoporosis and exerts an endocrine-modulating effect in ovariectomized rats.

The effect of warm needle moxibustion on lumbar disc herniation

OBJECTIVE

To investigate the effect of warm needle moxibustion on patients with lumbar disc herniation (LDH).

METHODS

A total of 100 patients with lumbar disc herniation treated in our hospital were recruited as the study cohort and randomly assigned into a control group and an observation group. The patients in the control group underwent routine acupuncture treatment, while those in the observation group underwent warm needle moxibustion treatment. The observed indexes, including the clinical efficacy, the visual analogue scale (VAS) scores, the Japanese Orthopedic Association (JOA) scores, the Oswestry disability index (ODI) scores, and the serum inflammatory factor levels were compared between the control group and the observation group.

RESULTS

The total cure rate in the observation group was significantly higher than it was in the control group (76.0% vs 92%, P=0.029). Compared with the patients in the control group after the treatment, the patients' VAS and ODI scores in the observation group were significantly lower, but their JOA scores were significantly higher, and the differences were statistically significant (all P<0.001). Moreover, the serum IL-6 and tumor necrosis factor α (TNF-α) levels in the observation group were remarkably lower than the corresponding levels in the control group (all P<0.001).

CONCLUSIONS

Warm needle moxibustion has a significant effect on patients with lumbar disc herniation, because it helps to relieve the pain and other symptoms and reduces the serum inflammatory factor levels.

Effects of acupoint catgut embedding on the postmenopausal osteoporosis patients and related mechanism

OBJECTIVE

To study the effect and mechanism of acupoint catgut embedding on patients of postmenopausal osteoporosis (PMOP).

METHODS

In this prospective study, 90 patients with PMOP who received treatment in our hospital were randomly divided into the drug treatment group (n=45) and drug treatment + catgut embedding group (n=45) according to SPSS random table method. The drug treatment group was given conventional western medicine treatment, and the drug treatment + catgut embedding group was given point embedding therapy. Bone mineral density (BMD), calcium (Ca²⁺), osteoprotegerin (OPG), estrogen (E₂), receptor activator of nuclear factor-kB ligand (RANKL), liver and kidney function and blood lipids were detected before treatment in the two groups, and visual analogue score (VAS) and PMOP symptom score were evaluated. The above-mentioned indexes were detected again 3 months and 6 months after treatment.

RESULTS

At 3 and 6 months after treatment, the BMD and the levels of Ca²⁺ and E₂ in the two groups were increased, while the levels of OPG and RANKL were decreased, and the improvement in the drug treatment + catgut embedding group was significantly better than that in the drug treatment group (P<0.05). The symptom scores of VAS and PMOP in the drug treatment + catgut embedding group were significantly lower than those in the drug treatment group (all P<0.001). There was no significant difference in the levels of alanine aminotransferase (ALT), total bilirubin (TBil), albumin (ALB), blood urea nitrogen (BUN), serum creatinine (SCr) and serum uric acid (SUA) between the two groups, but the levels of total cholesterol (TC) and triglyceride (TG) in the drug treatment + catgut embedding group were significantly lower than those in the drug treatment group (all P<0.001).

CONCLUSION

Acupoint catgut embedding has a good effect on PMOP, and it can increase BMO and improve the clinical symptoms of patients, which is worthy of clinical promotion.

Effectiveness of electroacupuncture as a treatment for osteoporosis: A systematic review and meta-analysis

BACKGROUND

Osteoporosis (OP) results in an increased risk of fragility fractures, representing a major public health problem. In preventing OP, complementary and alternative medicine, such as acupuncture, was recommended because of the low efficiency and side effects of medications. Recently, there is insufficient evidence on electroacupuncture as an effective therapy for OP management. Hence, we evaluated the effectiveness of electroacupuncture for OP treatment.

METHODS

We conducted a systematic review and meta-analysis of clinical studies on patients with OP. Five databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and Wanfang) were searched from the earliest publication date to March 12, 2020. Randomized controlled trials (RCTs) were included if electroacupuncture was applied as the sole treatment or as an adjunct to other treatments compared with medications in patients with OP. The measurement outcomes included serum aminoterminal propeptide of type I procollagen (PINP) and C-telopeptide of type I collagen (CTX) levels, bone mineral density (BMD) of lumbar, and visual analog scale scores for OP-related pain. Acupoints were extracted when available.

RESULTS

In total, 11 RCTs involving 731 participants were included for further meta-analysis. The meta-analysis showed that the use of electroacupuncture as a sole treatment or as an adjunct to other treatments could relieve OP-related pain compared with medications [mean difference (MD) =  -0.58, 95% confidence interval (CI); MD =  -0.97 to -0.19, P = .003, I2 = 88%; MD =  -1.47, 95% CI = -2.14 to -0.79, P < .001, I2 = 96%). Meanwhile, the results showed a favorable effect of electroacupuncture on decreasing serum beta-CTX levels. However, there were no significant differences in serum PINP levels and BMD of lumbar. Shenshu (BL23) was the most frequent acupoint stimulation among these studies.

CONCLUSIONS

The application of electroacupuncture as an independent therapy or as an adjunct to other treatments might attenuate OP-related pain and serum beta-CTX levels. However, to overcome the methodological shortcomings of the existing evidence, due to a small size of samples and high risk of bias in these included RCTs, further rigorous studies are required.

Acupuncture and moxibustion for primary osteoporosis: An overview of systematic review

Primary osteoporosis (PO) is a common disease that was characterized by a systemic impairment of bone mass and microarchitecture that results in fragility fractures and constitutes a pressing public health problem. But the effect of acupuncture or moxibustion treatment for PO is controversial.To provide a comprehensive systematic overview of current evidence from systematic reviews (SR)/Meta-analysis of acupuncture treatment for PO pertaining to risk of bias, quality of evidence and report quality.A total of 9 international and Chinese databases were searched for SR/meta-analysis of randomized controlled trials (RCTs). The risk of bias of SR/meta-analysis was appraised using the risk of bias in systematic reviews (ROBIS) instrument, the quality of the evidence was evaluated via Grading of Recommendations Assessment, Development and Evaluation (GRADE), and the report quality of the included studies are estimated by Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA).According to ROBIS, only 2 articles were with risk of low bias; according to PRISMA, and most articles were reported incomplete, mainly in Q2, Q7, Q24, and Q27; according to GRADE, a total of 28 outcome indicators were evaluated under 4 different interventions of experimental group and control group: the evidence quality of bone mineral density (BMD) from treatment of acupuncture and moxibustion/acupuncture and moxibustion plus was high or moderate; Visual Analogue Score (VAS) of acupuncture plus moxibustion or acupuncture plus moxibustion plus other was low or very low; clinical effectiveness of acupuncture plus moxibustion or acupuncture plus moxibustion plus other was uncertain.Acupuncture and moxibustion can improve the BMD of PO patients according to high-quality evidence, and may benefit VAS, pain score, clinical efficacy based on moderate or low-quality evidence. Further research that provides higher quality evidence of SR/RCTs of acupuncture and moxibustion treatment for PO is required.

Acupuncture for the Relief of Chronic Pain: A Synthesis of Systematic Reviews

Background and Objectives: It is estimated that 28 million people in the UK live with chronic pain. A biopsychosocial approach to chronic pain is recommended which combines pharmacological interventions with behavioural and non-pharmacological treatments. Acupuncture represents one of a number of non-pharmacological interventions for pain. In the current climate of difficult commissioning decisions and constantly changing national guidance, the quest for strong supporting evidence has never been more important. Although hundreds of systematic reviews (SRs) and meta-analyses have been conducted, most have been inconclusive, and this has created uncertainty in clinical policy and practice. There is a need to bring all the evidence together for different pain conditions. The aim of this review is to synthesise SRs of RCTs evaluating the clinical efficacy of acupuncture to alleviate chronic pain and to consider the quality and adequacy of the evidence, including RCT design. Materials and Methods: Electronic databases were searched for English language SRs and meta-analyses on acupuncture for chronic pain. The SRs were scrutinised for methodology, risk of bias and judgement of efficacy. Results: A total of 177 reviews of acupuncture from 1989 to 2019 met our eligibility criteria. The majority of SRs found that RCTs of acupuncture had methodological shortcomings, including inadequate statistical power with a high risk of bias. Heterogeneity between RCTs was such that meta-analysis was often inappropriate. Conclusions: The large quantity of RCTs on acupuncture for chronic pain contained within systematic reviews provide evidence that is conflicting and inconclusive, due in part to recurring methodological shortcomings of RCTs. We suggest that an enriched enrolment with randomised withdrawal design may overcome some of these methodological shortcomings. It is essential that the quality of evidence is improved so that healthcare providers and commissioners can make informed choices on the interventions which can legitimately be provided to patients living with chronic pain.

The Effectiveness and Safety of Acupoint Catgut Embedding for the Treatment of Postmenopausal Osteoporosis: A Systematic Review and Meta-Analysis

Purpose

To evaluate the effectiveness and safety of acupoint catgut embedding therapy (ACET) in postmenopausal osteoporosis (PMOP).

Methods

Review of some databases from their inception to June 2018 and randomized controlled trials (RCTs) in which ACET with PMOP were included. Two researchers extracted and evaluated the information independently. Cochrane Collaboration's tool and Jadad scale were used to evaluate the quality of the studies. RevMan V.5.3.3 software was used to carry out the meta-analysis while trial sequential analysis (TSA) performed with TSA 0.9 software.

Results

12 RCTs with 876 participants were included in this review. Meta-analysis showed that ACET alone was not superior to medication in effectiveness rate (RR= 1.11; 95% CI (0.89, 1.40); P=0.35) and E2 (SMD= 0.20; 95% CI (-0.17, 0.57); P=0.28; I ² =20%) while ACET combining medication was more effective on the effectiveness rate (RR= 1.32; 95% CI (1.20, 1.46); P<0.000 01) and E2 (SMD= 1.24; 95% CI (0.63, 1.84); P<0.0001). Additionally, ACET combining calcium could increase the bone mineral density (BMD) of the L2~4 vertebrae and femur-neck [WMD_L2~4 = 0.03; 95% CI (0.01, 0.05); P=0.003; and WMD_Femur-neck = 0.07; 95% CI (0.03, 0.10); P = 0.0006], reduce TCM syndrome score [WMD = -1.85; 95% CI (-2.13, -1.57); P<0.000 01], improve patient's quality of life [WMD_{three  months} = 6.90; 95% CI (3.90, 9.89); P<0.000 01; and WMD_{six  months} = 12.34; 95% CI (5.09, 19.60); P=0.0009], and relieve pain [WMD_VAS = -1.26; 95% CI (-1.66, -0.85); P<0.000 01; and WMD_{Pain  score} = -2.59; 95% CI (-4.76, -0.43); P= 0.02]. The TSA showed that the effectiveness of ACET for PMOP was demonstrated accurately.

Conclusions

ACET combining medication but not ACET alone is more effective than medication as comparison in the treatment of PMOP. As a novel treatment, ACET shows the potential of effectiveness and deserves further high quality of well-designed study.

Acupuncture for Primary Osteoporosis: Evidence, Potential Treatment Prescriptions, and Mechanisms

Many clinical trials and meta-analyses related to acupuncture for osteoporosis (OP) have been published. However, identifying the evidence from these studies still remains a challenge for acupuncturists. We conducted a systematic search of the Chinese Biomedical Medicine (CBM), VIP Database, Wanfang Data, China National Knowledge Infrastructure (CNKI), PubMed, Springer, Cochrane Library, and Embase to identify relevant trials, systematic reviews, and/or meta-analyses up to October 31, 2018. Data were extracted to assess the methodological quality using Veritas plots and to explore potential acupuncture prescriptions using the Traditional Chinese Medicine inheritance support system (TCMISS). In addition, potential mechanisms of core acupoints identified by data mining were summarized based on published studies. A total of 218 clinical trials and ten meta-analyses were included, involving 212 acupuncture prescriptions, 102 acupoints, 13 meridians, three extra meridians, and one Ashi point. The mean Veritas score of publication year, type of study, Assessment of Multiple Systematic Reviews 2, Preferred Reporting Items for Systematic Reviews and Meta-Analyses, heterogeneity, and publication bias were 5.5, 7.2, 6, 5.6, 5.8, and 7.5, respectively. The study of Pan et al. received the highest Veritas score of 8.67 points. The most frequently used meridian was BL. Acupoint combinations BL23 and BL20, BL23 and GV4, and BL23 and ST36 were used frequently. The core acupoints association networks were acupoints BL23, BL20, ST36, GV4, SP6, CV4, and KI3. The potential mechanisms of core acupoints involved upregulated expression of members in OPG/RANKL, Wnt/β-catenin, and MAPK pathways, such as LRP5, β-catenin, Runx2, and OPG. In conclusion, our Veritas plots enable acupuncturists to evaluate key attributes of meta-analysis quality related to acupuncture for primary OP and to improve the quality of evidence-based medicine relating to acupuncture. Data mining analysis revealed an association network of meridians, acupoint combinations, core acupoints, and the underlying mechanisms of acupuncture for primary OP.

Efficacy and safety of Zuogui Pill in treating osteoporosis: Study protocol of a systematic review

BACKGROUND

Osteoporosis (OP) is a common skeletal disorder worldwide, resulting in increased bone fragility and high risk of fractures. The Zuogui Pill (ZGP), a classic Chinese herbal formulation, has played a vital role in the clinical practice of OP in China for centuries. Increasing studies have been performed for clarifying its anti-osteoporotic mechanisms. However, this treatment still lacks a systematic review for its efficacy and safety in the treatment of OP.

METHODS

Eight electronic databases will be searched from inception to November 2018 by 2 independent researchers, in order to collect qualified randomized controlled trials (RCTs) on the ZGP treatment for OP. The therapeutic effects according to bone mineral density (BMD) will be adopted as the primary outcomes. RevMan V.5.3 software will be used for the data synthesis and the Cochrane's risk of bias assessment tool will be used to assess the risk of bias.

RESULTS

This review will conduct a high-quality synthesis on present evidence of ZGP for OP.

CONCLUSION

The conclusion of the study will indicate whether ZGP is an effective treatment for OP by providing updated evidence.PROSPERO registration number: PROSPERO CRD 42018114366.

BACKGROUND

Warm needle acupuncture (WNA) combines acupuncture and moxibustion, which is an integral part of the acupuncture therapy. Insomnia is a common sleep disorder, which affects sub-healthy people and patients with chronic disease. The clinical practice indicates that WNA has a therapeutic effect on insomnia. Here we will provide a protocol to explore the effectiveness and safety of WNA for insomnia.

METHODS

We will search the randomized controlled trails (RCT) literatures of WNA for insomnia in 9 electronic databases, including 5 English databases [PubMed, Web of Science, EMBASE, the Cochrane Central Register of Controlled Trials (Cochrane Library), and WHO International Clinical Trials Registry Platform (TCTRP)] and 4 Chinese databases [Chinese National Knowledge Infrastructure (CNKI), Chinese VIP Information, Wanfang Database, and Chinese Biomedical Literature Database (CBM)]. Sleep quality value of the patient will be considered as the primary outcome and the secondary outcome will include biochemical, indicators total scores on the insomnia severity index, quality of life, adverse events caused by WNA, and changes of symptom in Traditional Chinese Medicine. The selection of the studies will be performed by EndnoteX7 software. All analyses will be conducted by using RevMan software V5.3.

RESULT

This study will provide a rational synthesis of current evidences for warm needle acupuncture on insomnia.

CONCLUSION

The conclusion of this study will provide evidence to judge the effectiveness and safety of WNA on insomnia.
