Acupuncture and dry-needling for low back pain: an updated systematic review within the framework of the cochrane collaboration

Research trends between diabetes mellitus and bariatric surgery researches: Bibliometric analysis and visualization from 1998 to 2023

This study conducted a bibliometric analysis using the Web of Science Core Collection (WOSCC) to explore the relationship between diabetes mellitus and bariatric surgery (BS) from January 1985 to August 2023. No publications were found between 1985 and 1998. However, from 1998 to 2023, a total of 9,496 English articles were identified, accumulating 291,289 citations (241,563 excluding self-citations) and achieving an H-Index of 197. Leading contributors to the field were the United States, China, and Italy. Noteworthy authors in this area of research included Philip R. Schauer, Wei-Jei Lee, and Carel W. le Roux. The major journals that featured this research were 'Obesity Surgery,' 'Diabetes Care,' and 'Surgery for Obesity and Related Diseases.' The most highly cited article focused on lifestyle, diabetes, and cardiovascular risks 10 years after BS, emphasizing the significant attention given to the nutritional, cardiac, and general internal medicine impacts of diabetes and BS. The increase in research output during the review period indicates a growing interest in the relationship between diabetes and BS, providing a valuable reference for future studies in this evolving field.

Percutaneous tendon dry needling and thrust manipulation as an adjunct to multimodal physical therapy in patients with lateral elbow tendinopathy: A multicenter randomized clinical trial

OBJECTIVE

The purpose of this study was to assess the effects of adding electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization, and ultrasound in patients with lateral elbow tendinopathy.

DESIGN

Randomized, single-blinded, multicenter, parallel-group trial.

SETTING

Thirteen outpatient physical therapy clinics in nine different US states.

PARTICIPANTS

One hundred and forty-three participants (n = 143) with lateral elbow tendinopathy were randomized.

INTERVENTION

Cervical spine manipulation, extremity manipulation, and percutaneous tendon electrical dry needling plus multimodal physical therapy (n = 73) or multimodal physical therapy (n = 70) alone.

MAIN MEASURES

The primary outcome was elbow pain intensity and disability as measured by the Patient-Rated Tennis Elbow Evaluation at baseline, 1 week, 4 weeks, and 3 months. Secondary outcomes included the Numeric Pain Rating Scale, Tennis Elbow Functional Scale, Global Rating of Change, and medication intake.

RESULTS

The 2 × 4 analysis of covariance demonstrated that individuals with lateral elbow tendinopathy receiving electrical dry needling and thrust manipulation plus multimodal physical therapy experienced significantly greater improvements in disability (Patient-Rated Tennis Elbow Evaluation: F = 19.675; P < 0.001), elbow pain intensity (Numeric Pain Rating Scale: F = 22.769; P < 0.001), and function (Tennis Elbow Function Scale: F = 13.269; P < 0.001) than those receiving multimodal physical therapy alone at 3 months. The between-group effect size was large for pain and disability (Patient-Rated Tennis Elbow Evaluation: standardized mean difference = 1.13; 95% confidence interval: 0.78, 1.48) in favor of the electrical dry needling and thrust manipulation group.

CONCLUSIONS

The inclusion of percutaneous tendon electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization and ultrasound was more effective than multimodal physical therapy alone in individuals with lateral elbow tendinopathy.Trial Registration: www.clinicaltrials.gov NCT03167710 May 30, 2017.

The role of conservative treatment in lumbar disc herniations: WFNS spine committee recommendations

Objective

To formulate the most current, evidence-based recommendations for the conservative management of lumbar disc herniations (LDH).

Methods

A systematic literatüre search was performed 2012-2022 in PubMed/Medline and Cochrane using the keywords ''lumbar disc herniation'' and ''conservative treatment,'' yielding 342 total manuscripts. Screening criteria resulted in 12 final manuscripts which were summarized and presented at two international consensus meetings of the World Federation of Neurosurgical Societies (WFNS) Spine Committee. The Delphi method was utilized to arrive at three final consensus statements.

Results and conclusion

s: In the absence of cauda equina syndrome, motor, or other serious neurologic deficits, conservative treatment should be the first line of treatment for LDH. NSAIDs may significantly improve acute low back and sciatic pain caused by LDH. A combination of activity modification, pharmacotherapy, and physical therapy provides good outcomes in most LDH patients.

Spinal manipulation and electrical dry needling as an adjunct to conventional physical therapy in patients with lumbar spinal stenosis: a multi-center randomized clinical trial

BACKGROUND CONTEXT

Nonoperative management of lumbar spinal stenosis (LSS) includes activity modification, medication, injections, and physical therapy. Conventional physical therapy includes a multimodal approach of exercise, manual therapy, and electro-thermal modalities. There is a paucity of evidence supporting the use of spinal manipulation and dry needling as an adjunct to conventional physical therapy in patients with LSS.

PURPOSE

This study aimed to determine the effects of adding thrust spinal manipulation and electrical dry needling to conventional physical therapy in patients with LSS.

STUDY DESIGN/SETTING

Randomized, single-blinded, multi-center, parallel-group clinical trial.

PATIENT SAMPLE

One hundred twenty-eight (n=128) patients with LSS from 12 outpatient clinics in 8 states were recruited over a 34-month period.

OUTCOME MEASURES

The primary outcomes included the Numeric Pain Rating Scale (NPRS) and the Oswestry Disability Index (ODI). Secondary outcomes included the Roland Morris Disability Index (RMDI), Global Rating of Change (GROC), and medication intake. Follow-up assessments were taken at 2 weeks, 6 weeks, and 3 months.

METHODS

Patients were randomized to receive either spinal manipulation, electrical dry needling, and conventional physical therapy (MEDNCPT group, n=65) or conventional physical therapy alone (CPT group, n=63).

RESULTS

At 3 months, the MEDNCPT group experienced greater reductions in overall low back, buttock, and leg pain (NPRS: F=5.658; p=.002) and related-disability (ODI: F=9.921; p<.001; RMDI: F=7.263; p<.001) compared to the CPT group. Effect sizes were small at 2 and 6 weeks, and medium at 3 months for the NPRS, ODI, and RMDI. At 3 months, significantly (p=.003) more patients in the MEDNCPT group reported a successful outcome (GROC≥+5) than the CPT group.

CONCLUSION

Patients with LSS who received electrical dry needling and spinal manipulation in addition to impairment-based exercise, manual therapy and electro-thermal modalities experienced greater improvements in low back, buttock and leg pain and related-disability than those receiving exercise, manual therapy, and electro-thermal modalities alone at 3 months, but not at the 2 or 6 week follow-up.

[Evidence-based interventions to treat chronic low back pain: treatment selection for a personalized medicine approach : German version]

INTRODUCTION

Chronic low back pain (cLBP) is highly prevalent in the United States and globally, resulting in functional impairment and lowered quality of life. While many treatments are available for cLBP, clinicians have little information about which specific treatment(s) will work best for individual patients or subgroups of patients. The Back Pain Research Consortium, part of the National Institutes of Health Helping to End Addiction Long-termSM (HEAL) Initiative, will conduct a collaborative clinical trial, which seeks to develop a personalized medicine algorithm to optimize patient and provider treatment selection for patients with cLBP.

OBJECTIVE

The primary objective of this article is to provide an update on evidence-based cLBP interventions and describe the process of reviewing and selecting interventions for inclusion in the clinical trial.

METHODS

A working group of cLBP experts reviewed and selected interventions for inclusion in the clinical trial. The primary evaluation measures were strength of evidence and magnitude of treatment effect. When available in the literature, duration of effect, onset time, carryover effect, multimodal efficacy, responder subgroups, and evidence for the mechanism of treatment effect or biomarkers were considered.

CONCLUSION

The working group selected 4 leading, evidence-based treatments for cLBP to be tested in the clinical trial and for use in routine clinical treatment. These treatments include (1) duloxetine, (2) acceptance and commitment therapy, (3) a classification-based exercise and manual therapy intervention, and (4) a self-management approach. These interventions each had a moderate to high level of evidence to support a therapeutic effect and were from different therapeutic classes.

Improvements after dry needling for craniofacial pain in a patient with chronic rhinosinusitis: a case report

BACKGROUND

Typically treated medically, chronic rhinosinusitis (CRS) is a prevalent condition characterized by multiple craniofacial symptoms, some of which may respond favorably to dry needling intervention.

OBJECTIVE

To describe the outcomes of a patient presenting with craniofacial pain and symptoms consistent with a diagnosis of CRS who was treated with dry needling. Case Description: A 41-year-old male, self-referred to physical therapy with a diagnosis of CRS, with a 20-year history of signs and symptoms associated with CRS, including craniofacial pain and headaches. The patient had been treated with multiple medication regimens over this time, including antihistamines, anti-inflammatories, decongestants, leukotriene inhibitors, and antibiotics; all of which provided only short-term relief. On initial examination, the patient was tender to palpation in multiple muscles of the head, neck, and face. Intervention consisted of dry needling to these muscular tender points once or twice weekly over 2 months.

OUTCOMES

After 2 months of dry needling, the patient demonstrated clinically meaningful improvements in pain and quality of life, which included a decrease in both medication usage and the frequency of sinus infections.

CONCLUSION

Although CRS is generally managed medically, we observed areas of muscular tenderness in this case, which were effectively managed with dry needling. Rehabilitative providers may consider screening CRS patients for muscular impairments that may be modifiable with dry needling. Further research should be performed to determine whether dry needling has a role in the management of CRS.

A Bibliometric Analysis of Acupuncture Therapy in the Treatment of Musculoskeletal Pain from 2003 to 2022

Background

Acupuncture therapy has been widely used in the treatment of musculoskeletal pain (MP) in many countries around the world. However, there are no bibliometric studies on acupuncture therapy for MP. Therefore, the aim of this study was to analyze the current status, frontiers and hot spots in the use of acupuncture therapy for the treatment of MP.

Methods

Literature on acupuncture therapy for MP was extracted from the Web of Science Core Collection database from 2003 to 2022. CiteSpace 6.2.R4 (64-bit) software was used to analyze the number and centrality of journals, countries, institutions, authors, references and keywords, and the functions of co-occurrence and clustering were applied to draw a visual knowledge map.

Results

Over the past 20 years, the annual journal publications have been on a steady upward trend, with 438 articles published in 143 journals, including Acupuncture in Medicine Journal published the most (28, 6.39%), JAMA-Journal of the American Medical Association was the journal with the highest impact factor (IF = 120.7003), USA dominated with the most publications (140, 31.96%) among 44 countries, and among 196 research organizations Kyung Hee University was the most prolific (19, 4.34%) and Ha, In-Hyuk was the most published author (9, 2.05%). "Acupuncture" is the most popular and highly sought after keywords. "Low back pain" is the keyword with the highest centrality.

Conclusion

This article provides the current situation of the use of acupuncture therapy in the treatment of MP in the past 20 years, and statistical analysis reveals that "low back pain", "knit osteoporosis" and "break cancer" are new research diseases related to acupuncture therapy for MP, and "myobasic trigger point" is a new research direction of acupuncture therapy for MP. Therefore, this study helps researchers grasp the research hotspots and provide certain references for in-depth research and future topic selection.

Improved Understanding of the Inflammatory Response in Synovial Fluid and Serum after Traumatic Knee Injury, Excluding Fractures of the Knee: A Systematic Review

BACKGROUND

Traumatic knee injury results in a 4- to 10-fold increased risk of post-traumatic osteoarthritis (PTOA). Currently, there are no successful interventions for preventing PTOA after knee injury. The aim of this study is to identify inflammatory proteins that are increased in serum and synovial fluid after acute knee injury, excluding intra-articular fractures.

METHODS

A literature search was done according to the PRISMA guidelines. Articles reporting about inflammatory proteins after knee injury, except fractures, up to December 8, 2021 were collected. Inclusion criteria were as follows: patients younger than 45 years, no radiographic signs of knee osteoarthritis at baseline, and inflammatory protein measurement within 1 year after trauma. Risk of bias was assessed of the included studies. The level of evidence was determined by the Strength of Recommendation Taxonomy.

RESULTS

Ten studies were included. All included studies used a healthy control group or the contralateral knee as healthy control. Strong evidence for interleukin 6 (IL-6) and limited evidence for CCL4 show elevated concentrations of these proteins in synovial fluid (SF) after acute knee injury; no upregulation in SF for IL-2, IL-10, CCL3, CCL5, CCL11, granulocyte colony-stimulating factor (G-CSF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) was found. Limited evidence was found for no difference in serum concentration of IL-1β, IL-6, IL-10, CCL2, and tumor necrosis factor alpha (TNF-α) after knee injury.

CONCLUSION

Interleukin 6 and CCL4 are elevated in SF after acute knee injury. Included studies failed to demonstrate increased concentration of inflammatory proteins in SF samples taken 6 weeks after trauma. Future research should focus on SF inflammatory protein measurements taken less than 6 weeks after injury.

Acupuncture-Induced Changes in Nociception, Measured by Pain-Related Evoked Potentials: A Pilot Mechanistic Study

Objective: The nociceptive system has been implicated in acupuncture analgesia, although acupuncture's precise mechanism of action remains unknown. Electric pain-related evoked potentials (PREPs) have emerged as an effective and reliable electrophysiologic method for evaluation of the human nociceptive system by electric stimulation of nociceptive Aδ and C fibers. This pilot mechanistic study aims to assess the feasibility of using advanced PREP techniques together with electroacupuncture and to use PREPs to characterize acupuncture's effect on nociception. Methods: Seven healthy volunteers underwent a previously designed electroacupuncture protocol using acupoints in the legs bilaterally, which has been demonstrated to induce systemic analgesia. Advanced PREP techniques involving tripolar stimulating electrode, varying interstimulus interval, and incorporating a cognitive task during PREPs were used. PREPs were assessed before electroacupuncture, during electroacupuncture, and 30 min after electroacupuncture. Subjective pain perception in response to the PREP-related electric pain stimuli delivered to the nondominant hand was assessed on the visual analog scale (VAS) at baseline, during electroacupuncture, and 30 min postelectroacupuncture. Results: Reliable PREP N1, P1, and N2 waves were obtained from all subjects at the following average latencies: N1 = 131.5 msec, P1 = 189.4 msec, and N2 = 231.1 msec. Electroacupuncture caused a significant reduction in PREP N1P1 wave amplitudes from 25.6 to 15.4 μV (p = 0.006) and electric pain perception on the VAS-from 2.86 to 2.14 (p = 0.008), compared to baseline. These effects were sustained at 30 min postacupuncture with N1P1 wave amplitude 17.2 μV (p = 0.030) and VAS 2.28 (p = 0.030), compared to baseline. Conclusions: Electroacupuncture causes significant changes in objective nociception, measured by PREP N1P1 wave amplitudes, and in subjective nociception, measured by the VAS, and these effects are sustained for 30 min after electroacupuncture. Planned future studies will involve chronic pain populations and will aim to assess acupuncture's longer term analgesic effects.

Short-Term Effects of Dry Needling with a Standard Exercise Program on Pain and Quality of Life in Patients with Chronic Mechanical Neck Pain

Background: This study aimed to determine the short-term effects of dry needling (DN) combined with a standard exercise program on pain and quality of life in patients with chronic mechanical neck pain (CMNP). Methods: Thirty-one patients with CMNP were randomly allocated to the experimental and control groups. The experimental group received DN and underwent a standard exercise program (one DN session and six exercise sessions) for two weeks, whereas the control group underwent the same exercise program alone for two weeks. The participants’ scores in the Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI), Short Form-36 Quality of Life Scale (SF-36 QOLS), and Beck Depression Inventory (BDI) before and after the intervention were assessed. Results: The control and experimental groups’ post-test NDI, NPRS, SF-36 QOLS, and BDI scores significantly differed from their baseline scores (p ≤ 0.05). The between-group comparison of the post-test scores using Wilcoxon rank-sum test revealed no significant differences between the NDI, NPRS, BDI, and SF-36 QOLS scores of both groups (p ≥ 0.05). Conclusions: One session of trigger point DN (TrP-DN) with exercise and exercise alone showed the same pain and quality-of-life outcomes after a two-week intervention. We did not recognise TrP-DN as an efficient intervention, not because we obtained evidence that it is ineffective, but because there were inadequate high-quality studies on the subject and unavailable data on the minimum quantity of injections required for better DN outcomes in CMNP patients.

Comparative efficacy and acceptability of non-pharmacological interventions in fibromyalgia: Protocol for a network meta-analysis

INTRODUCTION

Although several non-pharmacological interventions have been tested in the management of Fibromyalgia (FM), there is little consensus regarding the best options for the treatment of this health condition. The purpose of this network meta-analysis (NMA) is to investigate the comparative efficacy and acceptability of non-pharmacological interventions for FM, in order to assist clinical decision making through a ranking of interventions in relation to the most important clinical outcomes in these patients.

METHODS AND ANALYSIS

We will perform a systematic search to identify randomised controlled trials of non-pharmacological interventions endorsed in guidelines and systematic reviews. Information sources searched will include major bibliographic databases without language or date restrictions (MEDLINE, Cochrane Library, EMBASE, AMED, PsycINFO and PEDro). Our primary outcomes will be pain intensity, patient-reported quality of life (QoL), and acceptability of treatment will be our secondary outcome. Risk of bias of the included trials will be assessed using the Cochrane risk of bias tool (RoB2). For each pairwise comparison between the different interventions, we will present mean differences (MDs) for pain intensity and QoL outcomes and Relative Risks (RRs) for acceptability, both with respective 95% confidence intervals (CIs). Initially, standard pairwise meta-analyses will be performed using a DerSimonian-Laird random effects model for all comparisons with at least two trials and then we will perform a frequentist NMA using the methodology of multivariate meta-analysis assuming a common heterogeneity parameter, using the mvmeta command and network suite in STATA. In the NMA, two different types of control group, such as placebo/sham and no intervention/waiting list will be combined as one node called "Control". The competing interventions will be ranked using the P-score, which is the frequentist analogue of surface under the cumulative ranking curve (SUCRA) for the outcomes of interest at immediate- (intervention duration of up to 2 weeks), short- (over 2 weeks up to 12 weeks) and long-terms (over 12 weeks). The confidence in the results from NMA will be assessed using the Confidence in Network Meta-analysis (CINeMA) framework.

ETHICS AND DISSEMINATION

This work synthesises evidence from previously published studies and does not require ethics review or approval. A manuscript describing the findings will be submitted for publication in a peer-reviewed scientific journal.

Effectiveness of Dry Needling and Ischemic Trigger Point Compression in the Gluteus Medius in Patients with Non-Specific Low Back Pain: A Randomized Short-Term Clinical Trial

BACKGROUND

The presence of latent myofascial trigger points (MTrPs) in the gluteus medius is one of the possible causes of non-specific low back pain. Dry needling (DN) and ischemic compression (IC) techniques may be useful for the treatment of these MTrPs.

METHODS

For this study, 80 participants were randomly divided into two groups: the dry needling group, who received a single session of DN to the gluteus medius muscle plus hyperalgesia (n = 40), and the IC group, who received a single session of IC to the gluteus medius muscle plus hyperalgesia (n = 40). Pain intensity, the pressure pain threshold (PPT), range of motion (ROM), and quality of life were assessed at baseline, immediately after treatment, after 48 h, and one week after treatment.

RESULTS

Statistically significant differences were shown between the two groups immediately after the intervention, showing a decrease in PPT (p < 0.05) in the DN group and an increase in PPT in the IC group. These values increased more and were better maintained at 48 h and after one week of treatment in the DN group than in the IC group. Quality of life improved in both groups, with greater improvement in the DN group than in the IC group.

CONCLUSIONS

IC could be more advisable than DN with respect to UDP and pain intensity in the most hyperalgesic latent MTrPs of the gluteus medius muscle in subjects with non-specific low back pain, immediately after treatment. DN may be more effective than IC in terms of PPT, pain intensity, and quality of life in treating latent plus hyperalgesic gluteus medius muscle MTrPs in subjects with non-specific low back pain after 48 h and after one week of treatment.

Immediate Effect of Dry Needling on the Viscoelastic Properties of a Trigger Point on the Infraspinatus Muscle Measured with MyotonPRO

Purpose: This article investigates the immediate effects of a dry needling (DN) puncture on the viscoelastic properties (tone, stiffness, elasticity) of a trigger point (TP) in the infraspinatus muscle in non-traumatic chronic shoulder pain. Method: Forty-eight individuals with non-traumatic chronic shoulder pain were recruited. The presence of a TP in the infraspinatus muscle was confirmed by a standardized palpatory exam. The viscoelastic properties were measured with a MyotonPRO device at baseline (T1), immediately after DN (T2), and 30 minutes later (T3). A DN puncture was applied to the TP to obtain a local twitch response while performing the technique. Results: Analyses of variance showed significant decreases in tone ( p < 0.001) and stiffness ( p = 0.003) across time after the DN technique. Post hoc tests revealed a significant reduction in tone and stiffness from T1 to T2 ( p ≤ 0.004) and no significant changes from T2 to T3 ( p ≥ 0.10). At T3, only stiffness remained significantly lower compared to T1 ( p = 0.013). Conclusions: This study brings new insights on the immediate mechanical effect of DN on tone and stiffness of TPs. Whether these effects are associated with symptom improvement and long-term effects still needs to be verified.

Electrical dry needling versus conventional physiotherapy in the treatment of active and latent myofascial trigger points in patients with nonspecific chronic low back pain

Background

Chronic low back pain is considered to be one of the main causes of absenteeism from work and primary and specialized consultations. The symptoms of nonspecific chronic low back pain may be accompanied by the activation of myofascial trigger points in the muscles, together with local and/or referred pain. Electrical dry needling is increasingly used in the treatment of lumbar myofascial pain. Conventional physiotherapy, however, is a popular approach to chronic pathologies, and there is evidence of different modalities of physiotherapy being used in the treatment of chronic low back pain. The aim of this study has been to determine the effectiveness of electrical dry needling versus conventional physiotherapy when applied to active and latent myofascial trigger points in patients with nonspecific chronic low back pain.

Methods

This is a controlled, randomized, two-arm, double-blind study. A total of 92 patients with chronic low back pain (time to onset ≥ 3 months, Roland Morris Disability Questionnaire score ≥ 4) will be recruited from the University of Almería. Participants will be divided into two study groups (n = 40) to receive treatment of low back pain with electrical dry needling and conventional physiotherapy (ischaemic compression, analytic stretching and postural education training dossier). A total of 6 sessions will be administered once a week for 6 weeks. Pain intensity, disability, fear of movement, quality of life, quality of sleep, anxiety and depression, pressure pain threshold, abdominal strength and lumbar mobility will be recorded at 6 weeks (post-immediate) and 2 months after the end of treatment.

Discussion

We believe that an approach including electrical dry needling to chronic low back pain dysfunction will be more effective in these patients. The results of this study will inform clinicians on which type of treatment is more beneficial for patients with chronic low back pain.

Can Post-Exercise Hemodynamic Response Be Influenced by Different Recovery Methods in Paraplegic Sportsmen?

Post-exercise hypotension is of great clinical relevance and also in sports training settings, as recovery speed is important. The aim of this study was to compare the influence of different recovery methods on post-exercise hemodynamic response. Twelve male paraplegic sportsmen (25.40 ± 3.30 years) performed a strength training (ST) session using the bench press exercise. After the ST, three recovery methods were randomly performed over a 15-min period: passive recovery (PR), cold-water (CW) and dry needle (DN). Blood pressure (BP), heart rate (HR) and myocardial oxygen were measured before and post ST, as well as post the recovery method. Results: Dry needling induced lower systolic blood pressure (SBP) immediately after the treatment when compared with the other recovery methods, but the contrary was observed at 50 and 60-min post recovery, where records with DN exhibit higher mean values (η²p = 0.330). There were no differences in post-exercise diastolic BP and mean BP between recovery methods. There was a significantly higher HR after the PR method, when compared with CW and with DN (η²p = 0.426). The same was observed for double product and for myocardial oxygen, though with a larger effect size (η²p = 0.446). We conclude that dry needling seems to induce a faster SBP lowering immediately after the procedure but at 50-min post procedure the cold-water method showed better result. As for HR, both procedures (DN and CW) showed a better recovery when compared with passive recovery, along the several moments of measurement.

EFFECT OF THE MAITLAND CONCEPT TECHNIQUES ON LOW BACK PAIN: A SYSTEMATIC REVIEW

ABSTRACT Low back pain has a prevalence that reaches up to 70% of the population between 35-55 years of age and is the principal cause of occupational disability. The scientific evidence on the effect of manual therapy on low back pain is conflicting and there are no specific reviews on the Maitland concept of manual therapy. Therefore, the objective of this systematic review is to analyze the effect of the techniques of the Maitland concept of manual therapy in patients with low back pain and/or determine the level of scientific evidence.For this, a search was carried out in the Cinahl, Medline, Web of Science, PubMed and Scopus databases during the months of January and February 2021 and it was updated in August 2021. In the search, 894 records were obtained, of which 15 randomized clinical trials that obtained a minimum of 3 points out of 5 on the Jadad scale were included.The main results in the current scientific literature suggest that there is solid evidence that the manipulations and mobilizations described in the Maitland Concept, applied alone or in combination with other interventions, reduce pain and disability in subjects with low back pain.The effects on musculature are contradictory. Exercise and patient education increase the effect of manual therapy. Future research requires analyzing whether the effects are preserved in the long term and more homogeneous treatment protocols are needed to determine a prescriptive guideline for manual therapy. Level of evidence I; Systematic review.

Knowledge Mapping Analysis of International Research on Acupuncture for Low Back Pain Using Bibliometrics

Objective

Acupuncture has made recommendations to relieve low back pain (LBP) in a few guidelines. However, few articles focused on the papers published before, which may reflect the trend of study, main researchers, reciprocal collaboration, and other information in this field. In this study, we utilize the bibliometric analysis methods to objectively analyze the current trend and research hotspots about this field, aiming to provide a foundation and reference for future study.

Methods

The Web of Science database was searched for publications related to acupuncture therapy for treating low back pain between 1985 and 2021. VOSviewer and CiteSpace were used to analyze the annual publication, authors and co-cited authors and their countries (regions) and institutions, journals and co-cited journals, co-cited references, co-occurrence keywords, burst keywords, and the relevant centrality.

Results

A total of 1279 papers were retrieved from the database, and the trend of annual publications maintained growth. Article was the most document type (867). The USA (451) and the Kyung Hee University (49) were the most productive country (region) and institution, respectively, while the USA (0.37) and University of Maryland (0.13) had the highest centrality. MacPherson, Hugh and Sherman, Karen J. published the most papers in this field (32), and Ernst, Edzard became the most influential author (474 co-citations). Journal of Alternative and Complementary Medicine was the most productive journal (79), whereas SPINE was the most influential one (3111 co-citations). Haake's (2007) article had the most co-citation count (186), while Furlan's (2005) article had the highest centrality (0.23). The three frontier topics were pain management, disease, and protocol.

Conclusion

The present study investigated publications on acupuncture for treating low back pain using bibliometric analysis methods, which may help researchers explore the potential directions for the future.

Cost-effectiveness analysis of acupuncture compared with usual care for acute non-specific low back pain: secondary analysis of a randomised controlled trial

OBJECTIVE

To assess the cost-effectiveness of a single treatment session of acupuncture, when applied in addition to usual care for acute low back pain (ALBP).

METHODS

Secondary analysis of a multicentre randomised controlled trial in Norwegian general practice. In total, 171 participants with ALBP ⩽14 days were randomised to a control group (CG) receiving usual care or to an acupuncture group (AG) receiving one additional session of Western medical acupuncture alongside usual care. Primary outcome measures for this cost-effectiveness analysis were quality-adjusted life years (QALYs), health care costs and societal costs at days 28 and 365, the incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB). The NMB was calculated on the basis of the Norwegian cost-effectiveness threshold of NOK 275,000 (USD 35,628) per QALY gained. Missing data were replaced by multiple chained imputation.

RESULTS

Eighty-six participants in the CG and 81 in the AG were included in the analysis. We found no QALY gain at day 28. At day 365, the incremental QALY of 0.035 was statistically significant. The differences in health care costs and societal costs were not statistically significant. Three out of four calculations led to negative ICERs (cost saving) and positive NMBs. For the health care perspective at day 365, the ICER was USD -568 per QALY and the NMB was USD 1265, with 95.9% probability of acupuncture being cost-effective.

CONCLUSION

To our knowledge, this is the first cost-effectiveness analysis of acupuncture for ALBP. The findings indicate that acupuncture may be cost-effective from a 1-year perspective, but more studies are needed.

A mixed-methods survey of physiotherapists who practice acupuncture and dry needling in Ontario, Canada: practice characteristics, motivations, and professional outcomes

Background

Physiotherapists (PTs) across the globe are increasingly incorporating filiform needling techniques (e.g., acupuncture, dry needling) into their clinical toolkits; and, the evidence base for these complementary therapies is becoming progressively more robust. However, to date, little is known about needling PTs themselves.

Methods

Using a cross-sectional survey design, PTs authorized to perform needling therapies in Ontario, Canada were recruited for anonymous participation (n = 2061) in an online survey. The survey asked providers about their demographics and practice characteristics, rationale for and views about therapeutic needling, and their related clinical and professional outcomes. The response rate was 20.7% (n = 426), and 22.3% (n = 95) of respondents provided textual responses to an open-ended qualitative question.

Results

While study respondents’ demographic features appear similar to their broader professional population, Ontario’s needling PTs are less likely to work in public sector settings. Most completed training in medical acupuncture rather than dry needling, and typically used needling in over one-third of patient visits. Almost all endorsed needling as an effective musculoskeletal treatment, the primary factor informing their adoption of the practice. While many viewed traditional Chinese medical theories as a useful explanatory framework, most relied on biomedical epistemology to drive their needling work. A majority of respondents reported that the inclusion of needling within their clinical toolkits had improved their likelihood of achieving excellent clinical results, helped support patient recruitment and retention, and heightened their professional satisfaction. While a few reported earning a higher income as a result, most reported that their clinical use of needling in addition to other PT modalities reduced their physical fatigue after a day’s work.

Conclusions

This study represents a first scholarly investigation into the motivations, training backgrounds and practice patterns of PTs who use acupuncture or dry needling. Additional research from other jurisdictions is needed to evaluate the transferability of study findings.

Can Acupuncture Improve Chronic Spinal Pain? A Systematic Review and Meta-Analysis

STUDY DESIGN

Systematic review and meta-analysis.

OBJECTIVE

To investigate the effect and safety of acupuncture for the treatment of chronic spinal pain.

METHODS

MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, the WHO Clinical Trial Registry, and the US National Library of Medicine clinical trial registry were searched from January 1, 2000, to November 1, 2019. Randomized controlled trials (RCTs) involving patients with chronic spinal pain treated by acupuncture versus sham acupuncture, no treatment, or another treatment were included.

RESULTS

Data was extracted from 22 RCTs including 2588 patients. Pooled analysis revealed that acupuncture can reduce chronic spinal pain compared to sham acupuncture (weighted mean difference [WMD] -12.05, 95% confidence interval [CI] -15.86 to -8.24), mediation control (WMD -18.27, 95% CI -28.18 to -8.37), usual care control (WMD -9.57, 95% CI -13.48 to -9.44), and no treatment control (WMD -17.10, 95% CI -24.83 to -9.37). In terms of functional disability, acupuncture can improve physical function at immediate-term follow-up (standardized mean difference [SMD] -1.74, 95% CI -2.04 to -1.44), short-term follow-up (SMD -0.89, 95% CI -1.15 to -0.62), and long-term follow-up (SMD -1.25, 95% CI -1.48 to -1.03).

CONCLUSION

In summary, compared to no treatment, sham acupuncture, or conventional therapy such as medication, massage, and physical exercise, acupuncture has a significantly superior effect on the reduction in chronic spinal pain and function improvement. Acupuncture might be an effective treatment for patients with chronic spinal pain and it is a safe therapy.

The Role of Skin Mast Cells in Acupuncture Induced Analgesia in Animals: A Preclinical Systematic Review and Meta-analysis

While mast cells (MCs) are previously well-known as a pathological indicator of pain, their role in alleviating pain is recently emerged in acupuncture research. Thus, this study systematically reviews the role of MC in acupuncture analgesia. Animal studies on MC changes associated with the acupuncture analgesia were searched in PubMed and EMBASE. The MC number, degranulation ratio and pain threshold changes were collected as outcome measures for meta-analyses. Twenty studies were included with 13 suitable for meta-analysis, most with a moderate risk of bias. A significant MC degranulation after acupuncture was indicated in the normal and was significantly higher in the pain model. In the subgroup analysis by acupuncture type, manual (MA) and electrical (EA, each P < .00001) but not sham acupuncture had significant MC degranulation. Meta-regression revealed the linear proportionality between MC degranulation and acupuncture-induced analgesia (P < .001), which was found essential in MA (P < .00001), but not in EA (P = .45). MC mediators, such as adenosine and histamine, are involved in its mechanism. Taken together, skin MC is an essential factor for acupuncture-induced analgesia, which reveals a new aspect of MC as a pain alleviator. However, its molecular mechanism requires further study. PERSPECTIVE: This systematic review synthesizes data from studies that examined the contribution of skin MC in acupuncture analgesia. Current reports suggest a new role for skin MC and its mediators in pain alleviation and explain a peripheral mechanism of acupuncture analgesia, with suggesting the need of further studies to confirm these findings.

Traditional Chinese Medicine in the United States: Current state, regulations, challenges, and the way forward

In the United States, there has been a steady presence and growth of Traditional Medicine (interchangeable in this paper with Complementary or Alternative Medicine) over the past few decades. The costs for such practices are relatively low along with minimal-to-no obvious side effects. Amongst a variety of traditional medical systems, Traditional Chinese Medicine is one of the most popular alternatives to help manage chronic health conditions or to improve the overall quality of life. While not exhaustive, this paper provides a snapshot of Traditional Chinese Medicine in the United States with insights into its current state, regulations, challenges, and the way forward.

Spinal Manipulation and Electrical Dry Needling in Patients With Subacromial Pain Syndrome: A Multicenter Randomized Clinical Trial

OBJECTIVES

To compare the effects of spinal thrust manipulation and electrical dry needling (TMEDN group) to those of nonthrust peripheral joint/soft tissue mobilization, exercise, and interferential current (NTMEX group) on pain and disability in patients with subacromial pain syndrome (SAPS).

DESIGN

Randomized, single-blinded, multicenter parallel-group trial.

METHODS

Patients with SAPS were randomized into the TMEDN group (n = 73) or the NTMEX group (n = 72). Primary outcomes included the Shoulder Pain and Disability Index and the numeric pain-rating scale. Secondary outcomes included the global rating of change scale (GROC) and medication intake. The treatment period was 6 weeks, with follow-ups at 2 weeks, 4 weeks, and 3 months.

RESULTS

At 3 months, the TMEDN group experienced greater reductions in shoulder pain and disability (P<.001) compared to the NTMEX group. Effect sizes were large in favor of the TMEDN group. At 3 months, a greater proportion of patients within the TMEDN group achieved a successful outcome (GROC score of 5 or greater) and stopped taking medication (P<.001).

CONCLUSION

Cervicothoracic and upper-rib thrust manipulation combined with electrical dry needling resulted in greater reductions in pain, disability, and medication intake than nonthrust peripheral joint/soft tissue mobilization, exercise, and interferential current in patients with SAPS. The effects were maintained at 3 months. J Orthop Sports Phys Ther 2021;51(2):72-81. Epub 28 Aug 2020. doi:10.2519/jospt.2021.9785.

Effects of Dry Needling on Spasticity and Range of Motion: A Systematic Review

IMPORTANCE

This systematic review summarizes existing studies on dry needling for spasticity and range of motion (ROM) and discusses its potential for use as an occupational therapy intervention.

OBJECTIVE

To examine existing studies on the effects of dry needling on spasticity and ROM.

DATA SOURCES

Article citations and abstracts from Scopus, Cochrane Library, PubMed, CINAHL, and a university library search.

STUDY SELECTION AND DATA COLLECTION

Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used in abstracting data. Peer-reviewed journal articles published in English between January 2007 and June 2019 were searched. Of 270 identified studies, 10 met the inclusion criteria. Studies were divided into categories on the basis of outcome measures (Modified Modified Ashworth Scale and ROM). Pain outcome measures were excluded because a systematic review addressing this outcome has recently been completed.

FINDINGS

Strong evidence was found to support the use of dry needling to decrease spasticity and increase ROM.

CONCLUSIONS AND RELEVANCE

This systematic review suggests that dry needling is an effective physical agent modality to decrease spasticity and increase ROM, both of which are potentially beneficial to functional outcomes.

WHAT THIS ARTICLE ADDS

This article provides information that may be helpful in determining the appropriateness of dry needling as an occupational therapy intervention.

A sonographic comparison of the effect of dry needling and ischemic compression on the active trigger point of the sternocleidomastoid muscle associated with cervicogenic headache: A randomized trial

BACKGROUND

Cervicogenic headache (CeH) is among the common types of headache which has an undesirable influence on the quality of life. The myofascial trigger point (MTrP) within the sternocleidomastoid (SCM) muscle is one of the most important causes of CeH.

OBJECTIVE

The purpose of this study was to compare the effect of dry needling (DN) and ischemic compression (IC) on the headache symptoms as well as MTrP-related features in subjects with CeH originating from MTrPs of the SCM muscle using a sonographic method.

METHODS

A total of 29 female subjects aged 35.34 ± 12.19 on average with a clinical diagnosis of CeH originating from MTrP in the SCM muscle were randomly divided into the DN, IC, and control groups. Both DN and IC groups received 4 treatment sessions. Headache intensity, duration, frequency, MTrP elastic modulus, MTrP area, and pressure pain threshold (PPT) were assessed 2 weeks before and after treatments.

RESULTS

In both DN and IC groups, a significant improvement was found in the headache intensity, duration, frequency, PPT, and MTrP area (P< 0.05). No significant differences were observed between DN and IC (P> 0.05). Pearson correlation revealed a significant correlation between headache intensity and the MTrP elastic modulus (P< 0.05).

CONCLUSIONS

Both interventions could reduce headache symptoms, PPT, and MTrP area. Neither intervention was found to be superior to the other in short-term follow-up. IC may be preferred since it has fewer unwanted side effects compared to DN. Based on the data, it may be concluded that some MTrP biomechanical features such as stiffness may influence the produced headache symptoms.

Dry Needling Adds No Benefit to the Treatment of Neck Pain: A Sham-Controlled Randomized Clinical Trial With 1-Year Follow-up

OBJECTIVE

To examine the short- and long-term effectiveness of dry needling on disability, pain, and patient-perceived improvements in patients with mechanical neck pain when added to a multimodal treatment program that includes manual therapy and exercise.

DESIGN

Randomized controlled trial.

METHODS

Seventy-seven adults (mean ± SD age, 46.68 ± 14.18 years; 79% female) who were referred to physical therapy with acute, subacute, or chronic mechanical neck pain were randomly allocated to receive 7 multimodal treatment sessions over 4 weeks of (1) dry needling, manual therapy, and exercise (needling group); or (2) sham dry needling, manual therapy, and exercise (sham needling group). The primary outcome of disability (Neck Disability Index score) and secondary outcomes of pain (current and 24-hour average) and patient-perceived improvement were assessed at baseline and follow-ups of 4 weeks, 6 months, and 1 year by blinded assessors. Between-group differences were analyzed with a 2-way, repeated-measures analysis of variance. Global rating of change was analyzed with a Mann-Whitney U test.

RESULTS

There were no group-by-time interactions for disability (Neck Disability Index: F_2.37,177.47 = 0.42, P = .69), current pain (visual analog scale: F_2.84,213.16 = 1.04, P = .37), or average pain over 24 hours (F_2.64,198.02 = 0.01, P = .10). There were no between-group differences for global rating of change at any time point (P≥.65). Both groups improved over time for all variables (Neck Disability Index: F_2.37,177.47 = 124.70, P<.001; current pain: F_2.84,213.16 = 64.28, P<.001; and average pain over 24 hours: F_2.64,198.02 = 76.69, P<.001).

CONCLUSION

There were no differences in outcomes between trigger point dry needling and sham dry needling when added to a multimodal treatment program for neck pain. Dry needling should not be part of a first-line approach to managing neck pain. J Orthop Sports Phys Ther 2021;51(1):37-45. doi:10.2519/jospt.2021.9864.

Acute and Short-Term Effects of Dry Needling in Patients with Chronic Nonspecific Low Back Pain and Hamstring Tightness: A Pilot Study

BACKGROUND

Chronic nonspecific low back pain (LBP) is one of the common health issues. Hamstring tightness contributes to the development of LBP. This study aimed to investigate the acute and short-term effects of deep dry needling (DN) in patients with chronic nonspecific LBP and hamstring muscle tightness.

METHODS

A single-group pretest-posttest clinical study design was followed. The outcome measures were the visual analog scale (VAS), passive knee extension (PKE) test, finger-floor distance (FFD) test, and functional rating index (FRI). Patients underwent one session of deep DN of three points on both hamstring muscles, each point for one minute. Patients were assessed before (T0), immediately after (T1), and one week after DN (T2). The FRI was assessed at T0 and T2.

RESULTS

Ten women with a mean age of 21.1 years (SD = 1.6) participated in the study. Significant large effect sizes in VAS pain reduction (d = 1.25) and PKE hamstring tightness were obtained (hamstring: right, d = 0.82; left, d = 0.88) at T2. Medium effect sizes were obtained for FFD (d = 0.45) and FRI (d = 0.72) at T2.

CONCLUSION

A single session of deep DN improved pain and function and increased hamstring flexibility. This pilot study supports the use of DN in patients with LBP and hamstring tightness; however, future research with a rigorous study design of randomized controlled trial is required to confirm the findings. This trial is registered with IRCT20180511039612N1.

Evaluating the Characteristics, Reporting and Methodological Quality of Systematic Reviews of Acupuncture for Low Back Pain by Using the Veritas Plot

Objective

To evaluate systematic reviews (SRs) of acupuncture for low back pain (LBP) in terms of characteristics, reporting and methodological quality using a Veritas plot and to explore factors that may be associated with methodological quality and reporting quality.

Study Design and Setting

We searched 8 electronic bibliographic databases to find all SRs, and we evaluated the SRs' quality in 6 dimensions, including publication year, design type, homogeneity, risk of publication bias, methodological quality by Assessment of Multiple Systematic Reviews (AMSTAR) 2 and reporting quality by Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Excel 2010 and Adobe Illustrator CC were used to draw and optimize Veritas plots. Exploratory analysis was done using SPSS software version 23.0 to explore factors related to AMSTAR-2 and PRISMA scores. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) evidence quality evaluation tool was used to grade all the outcome indicators in the included literature.

Results

We included 19 SRs in the analysis. Literature quality rank scores ranged from 9.67 to 17.00, with an average score of 13.18 ± 2.35. The average score of AMSTAR-2 was 7.47, and the average score of PRISMA was 18.47. Overall, the main issues were research strategies, inclusion and exclusion criteria, publication bias, and registration in PROSPERO. The results of exploratory analysis showed that duplication of literature selected and appropriate tools to assess the risk of bias were related to the AMSTAR-2 score, and the summary of evidence was related to the PRISMA score. The GRADE quality evaluation results showed mainly low quality.

Conclusion

The quality of SRs on acupuncture for low back pain should be improved, mainly by strengthening the methodological quality and reporting quality. The Veritas plot is an effective graphical evaluation method that is worth popularizing.

Intramuscular stimulation vs sham needling for the treatment of chronic midportion Achilles tendinopathy: A randomized controlled clinical trial

Background

The insertion of filiform needles intramuscularly (a.k.a. intramuscular stimulation/dry needling) has been suggested as a possible treatment for various painful musculoskeletal conditions. Our aim was to answer the question, is intramuscular stimulation more effective than sham intramuscular stimulation/dry needling for the treatment of Achilles tendinopathy?

Methods

52 participants with persistent midportion Achilles tendinopathy began and 46 completed one of three treatment protocols which were randomly assigned: (G3) a 12-week rehabilitation program of progressive tendon loading plus intramuscular stimulation (n = 25), (G2) the same rehabilitation program but with sham intramuscular stimulation (n = 19), or (G1) a reference group of rehabilitation program alone (as an additional control) (n = 8). The a priori primary outcome measure was change in VISA-A score at 12 weeks–VISA-A was also measured at 6 weeks, and at 6 and 12 months. Secondary outcome measures include the proportion of patients who rated themselves as much or very much improved (%), dorsiflexion range of motion (degrees), and tendon thickness (mm).

Results

The study retention was 94% at 12 weeks and 88% at 1 year. VISA-A score improved in all three groups over time (p<0.0001), with no significant difference among the three groups in VISA-A score at the start of the study (mean ± SD: G3 59 ± 13, G2 57 ± 17, G1 56 ± 22), at 12 weeks (G3 76 ± 14, G2 76 ± 15, G1 82 ± 11) or at any other timepoint. The percentage of patients who rated themselves as much or very much improved (i.e. treatment success) was not different after 12 weeks (G3 70%, G2 89%, G1 86% p = 0.94), or at 26 (p = 0.62) or 52 weeks (p = 0.71). No clinically significant effects of intervention group were observed in any of the secondary outcome measures.

Conclusion

The addition of intramuscular stimulation to standard rehabilitation for Achilles tendinopathy did not result in any improvement over the expected clinical benefit achieved with exercise-based rehabilitation alone.

Combination Acupuncture and Cupping for Treating Adult Idiopathic Scoliosis

Background: There is limited previous English-language literature on acupuncture's ability to treat idiopathic scoliosis. This report shows the potential effectiveness of a combination of acupuncture and cupping therapies to treat curvature progression and thoracic back pain in adult idiopathic scoliosis. Intervention: A 34-year-old male veteran of the U.S. Armed Forces with thoracic back pain and muscle spasms originally presented to the chiropractic clinic at the Fargo Veterans Affairs Healthcare System, Fargo, ND. Per radiographs taken prior to the consultation, the chiropractor determined that the patient had an idiopathic right-convex scoliosis curve of ∼21°. Due to immobility of the thoracic spinal vertebra upon adjustment, he was referred to acupuncture care. After a clinical review, the acupuncturist hypothesized that a combination of utilizing acupuncture and cupping techniques would help relax the muscles along the thoracic spine, allowing correction of the patient's abnormal spinal curvature. Combination Traditional Chinese Medicine (TCM), using acupuncture with cupping therapy was given ∼2 times per week for several weeks, resulting in a total of 15 treatments. Results: After 15 treatments, this patient's subjective pain decreased by 85%. Anecdotally, he reported "feeling a bit looser." He continued to receive acupuncture and cupping treatments when his schedule allowed. Conclusions: The combination therapy was effective for treating musculoskeletal pain but was inconclusive with respect to its ability to treat adult idiopathic scoliosis. More research is needed on the efficacy of TCM for treating adult idiopathic scoliosis.

Pragmatic Randomized Controlled Pilot Trial on Trigger Point Injections With 1% Lidocaine Versus Conventional Approaches for Myofascial Pain in the Emergency Department

BACKGROUND

Myofascial neck and back pain is an increasingly common chief symptom in the emergency department. Currently, there are no widely accepted conventional therapies, and there is little evidence on the efficacy of interventions such as trigger point injections (TPIs).

OBJECTIVE

This study evaluates whether TPIs with 1% lidocaine can improve myofascial back and neck pain compared with conventional therapies. Secondary outcomes include changes in length of stay and number of opioid prescriptions on discharge.

METHODS

This single-center, prospective, randomized, pragmatic trial was carried out in patients clinically determined to have myofascial back or neck pain. Patients were randomized into the experimental arm (TPI with 1% lidocaine) or the control arm (standard conventional approach). Numeric Rating Scores (NRS) for pain and additional surveys were obtained prior to and 20 min after the intervention.

RESULTS

The NRS for pain was lower in the TPI group compared with the control group after adjustment for initial pain (median difference -3.01; 95% confidence interval -4.20 to -1.83; p < 0.001). Median length of stay was 2.61 h for the TPI group and 4.63 h for the control group (p < 0.001). More patients in the control group (47.4%) were discharged home with an opioid compared with the TPI group (2.9%) (p < 0.001).

CONCLUSIONS

TPI is an effective method for managing myofascial pain in the emergency department. This study indicates it may improve pain compared with conventional methods, reduce length of stay in the emergency department, and reduce opioid prescriptions on discharge.

The cerebral mechanism of the specific and nonspecific effects of acupuncture based on knee osteoarthritis: study protocol for a randomized controlled trial

Background

Research on the effect of acupuncture has been limited. Whether the effect of acupuncture is equivalent to placebo has been the focus of debate in this field. This study will explore the specific and non-specific effects of acupuncture for knee osteoarthritis (KOA) by functional magnetic resonance imaging (fMRI).

Methods and design

Ninety participants diagnosed with KOA will be randomly divided into the acupuncture group, sham acupuncture group, and waiting list group in a ratio of 1:1:1. Except for the waiting list group, the other participants will receive acupuncture or sham acupuncture three sessions per week for 4 weeks respectively. The primary outcome will be the response rate which is defined on an individual basis as at least a 2-point decrease in the numerical rating scale (NRS) of pain at the end of intervention period compared with the baseline. fMRI scans will be performed at baseline and the end of the intervention period to examine the response of various brain regions. The secondary outcomes will include the Western Ontario and McMaster Osteoarthritis Index (WOMAC), State-Trait Anxiety Scale-State Anxiety Subscale (STAI-S), and Stanford Expectations of Treatment Scale (SETS). Pearson’s correlation coefficient will be performed to investigate the changes in brain activity and clinical variables.

Discussion

The results of our study will help to evaluate the specific and nonspecific effects of acupuncture combined with clinical and brain function changes based on KOA.

The effects of acupressure on the symptoms severity and function status and electrodiagnostic findings in patients with carpal tunnel syndrome

OBJECTIVE

This study aimed to evaluate the effects of acupressure on the symptoms severity, function status and electrodiagnostic findings in patients with Carpal tunnel syndrome (CTS).

DESIGN

This double blind, randomized, controlled clinical trial study was conducted on 57 patients with CTS that selected through convenience sampling. The patients were randomly assigned to three groups, including (1) acupressure; (2) placebo acupressure; and (3) control.

SETTING

The study was conducted in the medical centers affiliated to Semnan University of Medical Sciences, Iran.

INTERVENTION

The intervention groups received acupressure or placebo for one month. The control group received only routine cares (splints and analgesics) with no additional intervention.

PRIMARY OUTCOMES

The severity of symptoms and hand function were evaluated by the Boston Carpal Tunnel Syndrome Questionnaire, and electrodiagnostic findings, including Nerve Conduction Velocity (NCV), Distal Sensory Latency (DSL), and Distal Motor Latency (DML) were measured by Electromyography device before and after the intervention.

RESULTS

The results showed significant differences in the mean severity of symptoms, hand function, NCV, DSL, and DML before and after the intervention in the acupressure group (P < 0.05). Significant differences were also observed between the means difference in severity of symptoms, hand function, and NCV, DSL, and DML before and after the intervention in the three groups (P < 0.05).

CONCLUSION

According to the results, acupressure was effective in reducing the severity of clinical symptoms, improving the hand function, and improving the electrodiagnostic findings. Therefore, the application of acupressure can be recommended for improving clinical symptoms of patients with CTS.

Local and Systemic Analgesic Effects of Nerve-Specific Acupuncture in Healthy Adults, Measured by Quantitative Sensory Testing

OBJECTIVE

This study aims to assess whether acupuncture analgesia's effects are local or systemic and whether there is a dose response for these effects.

METHODS

Twenty-eight healthy volunteers aged 18-45 were randomized to two doses of acupuncture using points closely associated with peripheral nerves in the legs. The lower-dose group involved acupoints overlying the deep peroneal nerve (DP), and the higher-dose involved acupoints overlying the deep peroneal and posterior tibial nerves (DPTN). Baseline and acupuncture quantitative sensory testing (QST) assessments were obtained locally in the calf and great toe and systemically in the hand. Results were analyzed using factorial repeated-measures analysis of variance for each of the QST variables-cold detection threshold (CDT), vibration detection threshold (VDT), heat pain threshold (HP0.5), and heat pain perception of 5/10 (HP5.0). Location (leg/hand) and time (baseline/acupuncture) were within-subject factors. Intervention (DP/DPTN) was a between-subject factor.

RESULTS

CDT was increased in the calf (P < 0.001) and in the hand (P < 0.001). VDT was increased in the toe (P < 0.001) but not in the hand. HP0.5 was increased in the calf (P < 0.001) and in the hand (P < 0.001). HP5.0 was increased in the calf (P = 0.002) and in the hand (P < 0.001), with the local effect being significantly greater than the systemic (P = 0.004). In all of the above QST modalities, there was no difference between the low-dose (DP) and high-dose (DPTN) acupuncture groups.

CONCLUSIONS

Acupuncture caused comparable local and systemic analgesic effects in cold detection and heat pain perception and only local effects in vibration perception. There was no clear acupuncture dose response to these effects.

Immediate Effects of Dry Needling as a Novel Strategy for Hamstring Flexibility: A Single-Blinded Clinical Pilot Study

CONTEXT

There are numerous studies on the benefits of dry needling (DN) for pain relief. No studies exist examining the effects of DN on hamstring flexibility.

OBJECTIVE

To determine the immediate effects of DN on hamstring flexibility in healthy subjects with shortened hamstrings.

DESIGN

A single-blinded, pretest-posttest clinical pilot study.

SETTING

A university physiotherapy clinic.

SUBJECTS

A total of 15 healthy subjects (female = 11; age = 23.26 [4.3] y) with shortened hamstrings participated in this study.

INTERVENTION

Subjects received a single session of DN. Three locations on the hamstring muscle group were needled, each for 1 minute.

MAIN OUTCOME MEASURES

The active knee extension test, muscle compliance, passive peak torque, and stretch tolerance were measured at baseline, immediately, and 15 minutes after DN.

RESULTS

There were statistically significant improvements in all outcome measures immediately after DN and at the 15-minute follow-up. The effect sizes for all outcome measures were large (Cohen's d ≥ 0.8). No serious adverse events were observed with DN.

CONCLUSIONS

This is the first study that demonstrates the beneficial effects of DN on hamstring flexibility, muscle compliance, and stretch tolerance without added stretching. The beneficial effects of DN should encourage clinicians to use DN as a novel strategy for increasing muscle flexibility.

Benefits of dry needling of myofascial trigger points on autonomic function and photoelectric plethysmography in patients with fibromyalgia syndrome

Background:

Fibromyalgia syndrome (FMS) is a condition characterised by the presence of chronic, widespread musculoskeletal pain, low pain threshold and hyperalgesia. Myofascial trigger points (MTrPs) may worsen symptoms in patients with FMS.

Objective:

The purpose of this randomised controlled trial was to compare the effects of dry needling and transcutaneous electrical nerve stimulation (TENS) on pain intensity, heart rate variability, galvanic response and oxygen saturation (SpO2).

Methods:

74 subjects with FMS were recruited and randomly assigned to either the dry needling group or the TENS group. Outcomes measures (pain intensity, heart rate variability, galvanic skin response, SpO2 and photoplethysmography) were evaluated at baseline and after 6 weeks of treatment. 2×2 mixed-model analyses of variance (ANOVAs) were performed.

Results:

The mixed-model ANOVAs showed significant differences between groups for the sensory dimension of pain, affective dimension of pain, total dimension of pain, visual analogue scale (VAS) and present pain intensity (PPI) (P=0.001). ANOVAs also showed that significant differences between groups were achieved for very low frequency power of heart rate variability (P=0.008) and low frequency power (P=0.033). There were no significant differences in dry needling versus TENS groups on the spectral analysis of the photoplethysmography and SpO2.

Conclusions:

This trial showed that application of dry needling therapy and TENS reduced pain attributable to MTrPs in patients with FMS, with greater improvements reported in the dry needling group across all dimensions of pain. Additionally, there were between-intervention differences for several parameters of heart rate variability and galvanic skin responses.

Acupuncture Differentially Affects the High-Frequency Spectral Energy in Radial Pulse Positions Depending on Type of Lower Back Pain

Acupuncture is a core discipline in traditional Chinese medicine (TCM) and has been practised in China for centuries. In traditional acupuncture, pulse palpation is an important clinical diagnostic technique that guides practitioners in their treatment strategies as they evaluate the effectiveness of the treatment. This paper provides the findings of our investigation of acupuncture's effect on specific radial pulse spectral energies in 41 individuals with lower back pain (LBP), in response to a single acupuncture treatment delivered bilaterally at acupoints BL23, BL25, and BL40. Baseline assessments (vital signs and radial pulse diagnoses), primary outcome measures (radial pulse diagnoses), and secondary outcome measures (the Faces Pain Scale-Revised (FPS-R) and fingertip-to-floor (FTF) tests) were performed at specified intervals before and after the intervention. Our study provides novel information about the effects of acupuncture on the radial pulse spectral energy in individuals with different types of LBP. Our findings suggest that the right Chi pulse is an effective indicator to assess the effects of acupuncture in individuals with fixed, distended, or sharp pain, whereas the left Guan pulse is a potentially useful diagnostic technique to determine acupuncture's effects in individuals with dull, aching pain. The acupoints BL23, BL25, and BL40 provide effective treatment for LBP. Study participants with dull, aching pain had a significant improvement in their lumbar ranges of motion, and their pain rating scores were markedly decreased after acupuncture treatment.

Efficacy and tolerability of injectable collagen-containing products in comparison to trimecaine in patients with acute lumbar spine pain (Study FUTURE-MD-Back Pain)

Low back pain (LBP) represents an important subgroup of vertebrogenic pain with estimated prevalence around 80 %. Locally acting injectable collagen for topical application has recently extended the limited range of treatment options. The aim of the study was to evaluate the efficacy and safety of injectable collagen in patients with LBP. Patients suffering from LBP (< three months) were enrolled. They were administered either collagen 4 ml or trimecaine 1 % 4 ml in the form of subcutaneous paravertebral injections into eight pre-specified points (0.5 ml per each point) in the following schedule: two administrations in the first and second week, one in the third week. The pain intensity, Thomayer distance, Oswestry disability index, Lasseque test, quality of life, consumption of rescue medication and safety were evaluated. Exertional and rest pain, evaluated by a visual analogue scale, gradually decreased in both groups. Both treatments showed a statistically significant improvement in mobility and quality of life. The consumption of paracetamol as a rescue medication was significantly lower in patients treated with collagen than in the group treated with trimecaine (p=0.048). The analgesic efficacy of locally acting injectable collagen, as well as an analgesic sparing effect when compared to local anesthetics were demonstrated.

Periosteal Electrical Dry Needling as an Adjunct to Exercise and Manual Therapy for Knee Osteoarthritis: A Multicenter Randomized Clinical Trial

Objectives:

To compare the effects of adding electrical dry needling into a manual therapy (MT) and exercise program on pain, stiffness, function, and disability in individuals with painful knee osteoarthritis (OA).

Materials and Methods:

In total, 242 participants (n=242) with painful knee OA were randomized to receive 6 weeks of electrical dry needling, MT, and exercise (n=121) or MT and exercise (n=121). The primary outcome was related-disability as assessed by the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index at 3 months.

Results:

Individuals receiving the combination of electrical dry needling, MT, and exercise experienced significantly greater improvements in related-disability (WOMAC: F=35.504; P<0.001) than those receiving MT and exercise alone at 6 weeks and 3 months. Patients receiving electrical dry needling were 1.7 times more likely to have completely stopped taking medication for their pain at 3 months than individuals receiving MT and exercise (OR, 1.6; 95% confidence interval, 1.24-2.01; P=0.001). On the basis of the cutoff score of ≥5 on the global rating of change, significantly (χ²=14.887; P<0.001) more patients (n=91, 75%) within the dry needling group achieved a successful outcome compared with the MT and exercise group (n=22, 18%) at 3 months. Effect sizes were large (standardized mean differences >0.82) for all outcome measures in favor of the electrical dry needling group at 3 months.

Discussion:

The inclusion of electrical dry needling into a MT and exercise program was more effective for improving pain, function, and related-disability than the application of MT and exercise alone in individuals with painful knee OA.

Myofascial pain and treatment: Editorial

The first article featured in this quarter's overview deserves special attention. Margalef and colleagues developed the first viable animal model of trigger points (TrPs). They also provided evidence of glycosaminoglycans (GAGs) near TrPs, which is a new finding that deserves further scientific inquiry (Margalef et al 2019). In 2011, Stecco et al. already mentioned a possible role of hyaluronan, which constitutes a subgroup of GAGs, in the etiology of myofascial pain (Stecco et al 2011). Mayoral Del Moral and colleagues published an excellent study that showed very good inter-examiner reliability for identifying subjects with MPS for identifying specific muscles (Mayoral Del Moral et al 2018). Sollmann and colleagues described a new and objective method to identify TrPs, using T2 mapping with quantitative MRI-based techniques (Sollmann et al 2016). As usual, many new dry needling (DN) studies, reviews, manual TrP papers and case reports are included. Finally, we would like to thank Dr. Michelle Finnegan for her contributions to this overview paper during the past 5 years. Dr. Finnegan will be focusing on other professional endeavors and she will not return as a contributing author.

Evidence of efficacy of acupuncture in the management of low back pain: a systematic review and meta-analysis of randomised placebo- or sham-controlled trials

Objectives:

To assess the evidence for the efficacy of acupuncture for non-specific low back pain (NSLBP), compared with sham or placebo therapies.

Methods:

We searched Cochrane CENTRAL to December 2016, and conducted searches from 1980 to December 2016 in PubMed, MEDLINE and Embase. There were no regional restrictions applied. We included only randomised controlled trials of adults with NSLBP. Placebo/sham procedures were required of the control interventions. The trials were combined using meta-analysis when the data reported allowed for statistical pooling.

Results:

14 trials (2110 participants) were included in the review, and 9 were included in the meta-analysis. Immediately after the acupuncture treatment we found statistically significant differences in pain reduction between acupuncture and sham or placebo therapy (standardised mean difference (SMD) −0.40, 95% CI −0.54 to −0.25; I2 7%; 753 participants; 9 studies), but there were no differences in function (weighted mean difference (WMD) −1.05, 95% CI −3.61 to 1.52; I2 79%; 462 participants; 4 studies). At follow-up, there were significant differences in pain reduction (SMD −0.46, 95% CI −0.82 to −0.09; I2 67%), but not in function (WMD −0.98, 95%CI −3.36 to 1.40; I2 87%). We conducted subgroup analyses both immediately after treatment and at follow-up.

Conclusion:

There is moderate evidence of efficacy for acupuncture in terms of pain reduction immediately after treatment for NSLBP ((sub)acute and chronic) when compared to sham or placebo acupuncture.

Time effect for in-situ dry needling on the autonomic nervous system, a pilot study

Study design: Pilot study.Background: Dry needling has been an emerging treatment option for physical therapists over the last decade. Despite the fact that studies have demonstrated the overall benefit of dry needling, there is no clear understanding how long needles should be left in place (situ). This pilot study investigated the effects of needles remaining in situ based on autonomic responses over time.Methods: A convenience sample of 21 subjects were recruited for this study. Automated pupillometry was utilized to obtain a direct measure of autonomic nervous system activity. Directly following a baseline measurement, 8 type J Seirin Acupuncture needles were inserted paravertebral at the C7-T3 segments. A total of 8 post-needling 60 seconds pupil measurements were taken at 3 minutes intervals for 24 minutes post needling.Outcomes: A statistical significant difference in mean pupil diameter was found following the needle intervention (p < .01), which implies an increased sympathetic activity. This subject sample had a statistically significantly larger mean pupil diameter immediately after the needling, which lasted until measure point 7, at 18 minutes (P < .05). At measure point 8 there was no longer a statistical significant difference compared to the premeasurement measure.Discussion: The results of this study provide evidence that dry needling results in a significant increased activity of the sympathetic nervous system for up to 18 minutes. Between 18 and 21 minutes autonomic activity returned to a non-significant difference compared to baseline. The results of this study could assist clinicians in clinical decision making to determine needle placement time.
