Alexander Technique Lessons or Acupuncture Sessions for Persons With Chronic Neck Pain: A Randomized Trial

Altered coordination strategies during upright stance and gait in teachers of the Alexander Technique

Deterioration in movement and posture often occurs with aging. Yet there may be approaches to movement training that can maintain posture and movement coordination patterns as we age. The Alexander Technique is a non-exercise-based approach that aims to improve everyday movement and posture by increasing awareness and modulating whole-body postural muscle activity. This study assessed whether nineteen 55-72-year-old Alexander Technique teachers showed different posture and movement coordination patterns than twenty age-matched controls during a standing and walking protocol using 3D inertial sensors. During upright stance, Alexander Technique teachers showed lower centroidal sway frequency at the ankle (p = .04) and lower normalized jerk at the sternum (p = .05) than controls. During gait, Alexander Technique teachers had more symmetrical gait cycles (p = .04), more symmetrical arm swing velocity (p = .01), greater arm swing velocity (p < .01), greater arm swing range of motion (p = .02), and lower range of acceleration of the torso in the frontal plane (p = .03) than controls. Smoother control of upright posture, more stable torso motion, and less restrained arm mobility suggest that Alexander Technique training may counter movement degradation that is found with aging. Results highlight the important balance between mobility and stability within the torso and limbs.

Efficacy and Safety of Electro-Thumbtack Needle Therapy for Patients With Chronic Neck Pain: Protocol for a Randomized, Sham-Controlled Trial

Background

Chronic neck pain is a prevalent condition adversely impacting patients' wellbeing in both life and work experience. Electro-thumbtack needle (ETN) therapy, combining acupuncture with transcutaneous stimulation, might be one of the effective complementary and alternative medicine (CAM) therapies in treating chronic neck pain, although the evidence is scarce. This study aims to estimate the efficacy and safety of ETN therapy for chronic neck pain.

Methods and Analysis

This is a sham-controlled, randomized clinical trial. A total of 180 subjects will be randomly allocated to either the ETN group or the sham ETN group. Treatment will be administrated three times a week for four consecutive weeks, with a 6-month follow-up. The primary outcome measure will be the Numerical Rating Scale for neck pain (NRS-NP) over a period of the 4 weeks. Secondary outcome measures include the Northwick Park Neck Pain Questionnaire (NPQ), Neck Disability Index (NDI), Patient Global Impression of Change (PGIC), patient expectation, and preference assessment. The chi-square test or Fisher's exact test will be used for proportions of participants having clinically meaningful improvement. Analysis of covariance or repeated-measures analysis of variance will be applied to examine changes in the outcome measures from baseline.

Discussions

This prospective trial will contribute to evaluating the efficacy and safety of ETN in the treatment of chronic neck pain, with an intermediate-term follow-up. This study will provide further evidence for clinical neck pain management.

Ethics and Dissemination

This trial has been approved by the Research Ethical Committee of Guang'anmen Hospital (ethical approval number: 2021-039-KY-01). Recruitment began in March 2022 and will continue until December 2023. Dissemination plans include posters, WeChat, websites, and bulletin boards in hospital and communities.

Clinical Trial Registration

This trial is registered at ClinicalTrials.gov (identifier: NCT04981171).

Posture biofeedback increases cognitive load

Attention may be important for actively maintaining posture during computer tasks, resulting in a dual-task tradeoff, where maintaining posture through extrinsic feedback imposes cognitive load. Mindfulness may make intrinsic postural feedback (which imposes less cognitive load) more available. Therefore, we hypothesized that the use of biofeedback would improve posture and negatively impact game performance; additionally, higher levels of mindfulness would be associated with lower game performance costs in the biofeedback condition. Healthy young adult participants played a challenging computer game for 10 min with and without neck length biofeedback, in a counterbalanced repeated-measures design. For each condition, we assessed posture using neck shrinkage (percentage of best), and task performance (computer game score). Neck length was better retained and game performance was worse with biofeedback than without, consistent with the hypothesis that posture biofeedback imposed a cognitive load. In addition, participants with the most neck shrinkage suffered the greatest performance decrements from using biofeedback, and neck length retention during the task without biofeedback was associated with lower self-reported daily neck pain and higher self-reported mindfulness. Thus, those with the greatest need for postural feedback suffer the greatest performance decrements from extrinsic feedback. The results are consistent with the idea that mindfulness enables people to use intrinsic feedback to maintain posture without imposing a dual-task cost.

Efficacy of acupuncture treatment for chronic spontaneous urticaria: study protocol for a randomised controlled trial

INTRODUCTION

Chronic spontaneous urticaria (CSU) is a troublesome dermatological problem that can have a significant impact on quality of life. Previous studies have indicated that acupuncture may be beneficial for patients with CSU. However, well-designed studies determine the effects of acupuncture on CSU are rare. The aim of this study is to investigate the efficacy and safety of acupuncture treatment for patients with CSU.

METHODS AND ANALYSIS

This study is designed as a multicentre, parallel, three-arm, randomised, sham-controlled trial. A total of 330 patients diagnosed as CSU will be randomly allocated into three groups: the verum acupuncture group, the sham acupuncture group and the waiting-list control group in a 1:1:1 ratio. Patients in the verum and sham acupuncture groups will receive 16 treatment sessions over 4 weeks, while patients in the waiting-list control group will not receive any acupuncture treatment. The primary outcome is the changes of weekly urticaria activity scores at the end of treatment. Secondary outcomes include itching severity measurement, Dermatology Life Quality Index, Hamilton Depression Scale, Hamilton Anxiety Scale, Pittsburgh Sleep Quality Index and serum total IgE level. Adverse events will be recorded during the study observation period. All patients who are randomised in this study will be included in the intention-to-treat analysis.

ETHICS AND DISSEMINATION

Ethical approval of this study has been granted by the Sichuan Regional Ethics Review of Committee on Traditional Chinese Medicine (TCM) (ID: 2019 kl-006), the Medical Ethic Committee of the First Hospital of Wuhan (ID: (2019) number 7)) and the Medical Ethics Committee of the First Hospital of Hunan University of TCM (ID: HN-LLKY-2019-017-01/03) in three clinical centres in China, respectively. The results will be disseminated through peer-reviewed journals.

Effect of Electroacupuncture on Shoulder Subluxation in Poststroke Patients with Hemiplegic Shoulder Pain: A Sham-Controlled Study Using Multidimensional Musculoskeletal Ultrasound Assessment

OBJECTIVE

This study aimed to use multidimensional musculoskeletal ultrasound imaging technique to investigate the effect of electroacupuncture (EA) on shoulder subluxation in poststroke patients with hemiplegic shoulder pain.

METHODS

In this prospective single-blind, randomized, sham-controlled study, thirty-four patients with shoulder subluxation and hemiplegic shoulder pain were recruited and randomly assigned into the EA group or the sham EA (SEA) group. In the EA group, EA was applied to the Jian yu (LI15), Bi nao (LI14), Jian zhen (SI9), and Jian liao (TE14) acupoints. In the SEA group, the EA was applied 15 mm away from the Lou gu (SP7), Di ji (SP8), Jiao xin (KI8), and Zhu bin (KI9) acupoints. Both groups underwent treatment 30 minutes/day, five days a week, for two weeks using dense waves with a frequency of 2/100 Hz. A Visual Analogue Scale (VAS) was used to evaluate the effectiveness of treatment in reducing shoulder pain. Musculoskeletal ultrasound was used to evaluate the changes of measures of shoulder subluxation in multidimensions (i.e., the acromiohumeral distance, AHD; acromion-greater tuberosity, AGT; and acromion-lesser tuberosity, ALT). Both the within- and between-groups treatment effects were assessed.

RESULTS

The pain intensity measured by VAS and shoulder subluxation measured by musculoskeletal ultrasound (i.e., AHD, AGT, and ALT) showed significant (p < 0.05) within-group difference in both groups. The between-group difference appeared in the pain intensity (p < 0.05), while it disappeared in the three measures of shoulder subluxation (p > 0.05).

CONCLUSIONS

Using VAS for measuring pain intensity and multidimensional musculoskeletal ultrasound imaging technique for measuring shoulder subluxation, this study finds that the hemiplegic shoulder pain can be improved significantly by the EA while the shoulder subluxation cannot be. Our findings further reveal the analgesic mechanism of EA on hemiplegic shoulder pain following stroke.

Efficacy and central mechanism of acupuncture treatment in patients with neck pain: study protocol for a randomized controlled trial

Background

Acupuncture is effective for reducing the symptoms of neck pain (NP). However, the underlying mechanisms are not fully elucidated. Based on evaluating the efficacy of two acupuncture prescriptions for treating NP, this study aims to investigate the potential central mechanism of acupuncture treatment for NP by functional magnetic resonance imaging (fMRI).

Methods

This is a randomized controlled trial; 86 patients will be randomly assigned into two acupuncture treatment groups at a ratio of 1:1. The whole study period includes 2 weeks baseline, 2 weeks treatments, and 12 weeks follow-up (4 and 12 weeks after treatment). The pain severity, the neck disability index, the cervical range of motion, and the pressure pain threshold, etc., will be used to evaluate the clinical efficacy of two acupuncture prescriptions for NP treatment. The MRI scans will be performed to detect cerebral activity changes of 20 patients in each group. The clinical data and MRI data will be analyzed, respectively. Pearson correlation coefficient will be used to evaluate the association between changes of cerebral activity features and improvement of clinical symptoms.

Discussion

The results will provide further evidence for the clinical application of acupuncture in the treatment of NP.

Electroacupuncture vs Prucalopride for Severe Chronic Constipation: A Multicenter, Randomized, Controlled, Noninferiority Trial

INTRODUCTION

This multicenter, randomized, noninferiority trial compared electroacupuncture with prucalopride for the treatment of severe chronic constipation (SCC).

METHODS

Participants with SCC (≤ 2 mean weekly complete spontaneous bowel movements [CSBMs]) were randomly assigned to receive either 28-session electroacupuncture over 8 weeks with follow-up without treatment over 24 weeks or prucalopride (2 mg/d before breakfast) over 32 weeks. The primary outcome was the proportion of participants with ≥3 mean weekly CSBMs over weeks 3-8, based on the modified intention-to-treat population, with -10% as the noninferior margin.

RESULTS

Five hundred sixty participants were randomized, 280 in each group. Electroacupuncture was noninferior to prucalopride for the primary outcome (36.2% vs 37.8%, with a difference of -1.6% [95% confidence interval, -8% to 4.7%], P < 0.001 for noninferiority); almost the same results were found in the per-protocol population. The proportions of overall CSBM responders through weeks 1-8 were similar in the electroacupuncture and prucalopride groups (24.91% vs 25.54%, with a difference of -0.63% [95% confidence interval, -7.86% to 6.60%, P = 0.864]). Except during the first 2-week treatment, no between-group differences were found in outcomes of excessive straining, stool consistency, and quality of life. Adverse events occurred in 49 (17.69%) participants in the electroacupuncture group and 123 (44.24%) in the prucalopride group. One non-treatment-related serious adverse event was recorded in the electroacupuncture group.

DISCUSSION

Electroacupuncture was noninferior to prucalopride in relieving SCC with a good safety profile. The effects of 8-week electroacupuncture could sustain for 24 weeks after treatment. Electroacupuncture is a promising noninferior alternative for SCC (see Visual Abstract, http://links.lww.com/AJG/B776).

The Efficacy of Acupuncture Treatment for Attention Deficit Hyperactivity Disorder: A Systematic Review and Meta-Analysis

BACKGROUND

This study aimed to assess the efficacy of acupuncture for treating attention deficit hyperactivity disorder (ADHD) in children and adolescents.

PATIENTS AND METHODS

Systematic review and meta-analysis including randomized controlled trials that compared the effects of acupuncture treatment (AT) with pharmacotherapy (methylphenidate hydrochloride, MPH) among patients with ADHD. A total of 12 electronic databases were searched from inception until February 3, 2020. The main outcomes were the effective rate and post-treatment hyperactivity scores. We also assessed the incidence of adverse events and follow-up course.

RESULTS

A total of 10 studies involving 876 patients were included in this study. The meta-analysis revealed that AT yielded a significantly higher effective rate than MPH (odds ratio 2.239, 95% CI 1.438-3.487, p < 0.001, 8 studies), and that AT can reduce the hyperactivity scores to a lesser degree than MPH (standardized mean difference = -0.882, 95% CI -1.295 to -0.469, p < 0.001, 3 studies). Two studies reported no adverse events in the AT group, while one study suggested that AT can reduce adverse drug reactions. Furthermore, 3 studies concluded that the effects of AT were maintained, even after completion of treatment.

CONCLUSION

This study suggests that AT may be more beneficial than MPH therapy for ADHD patients. However, the evidence may be highly limited, especially considering the outcome of hyperactivity scores with the high risk of bias, very low GRADE, and small number of studies. Thus, further studies of rigorous design and high quality are needed to confirm and strengthen the results, especially in the Western part of the world. Additionally, well-designed randomized controlled trials that evaluate adverse events and include a long-term follow-up should be conducted to determine the efficacy, safety, and side effects of AT for ADHD in children and adolescents.

Do the effects of acupuncture vary between acupuncturists? Analysis of the Acupuncture Trialists' Collaboration individual patient data meta-analysis

OBJECTIVES

The degree to which the effects of acupuncture treatment vary between acupuncturists is unknown. We used a large individual patient dataset of trials of acupuncture for chronic pain to assess practitioner heterogeneity.

METHODS

Individual patient data linked to identifiable acupuncturists were drawn from a dataset of 39 high-quality trials of acupuncture, where the comparators were either sham acupuncture or non-acupuncture controls, such as standard care or waitlist. Heterogeneity among acupuncturists was assessed by meta-analysis.

RESULTS

A total of 1206 acupuncturists in 13 trials were included. Statistically significant heterogeneity was found in trials with sham-control groups (p < 0.0001) and non-acupuncture control groups (p <0.0001). However, the degree of heterogeneity was very small, with the observed distribution of treatment effects virtually overlapping that expected by chance. For instance, for non-acupuncture-controlled trials, the proportion of acupuncturists with effect sizes half a standard deviation greater or less than average was expected to be 34%, but was observed to be 37%. A limitation is that the trials included a relatively limited range of acupuncturists, mainly physician-acupuncturists.

DISCUSSION

Although differences in effects between acupuncturists were greater than expected by chance, the degree of variation was small. This suggests that most chronic pain patients in clinical practice would have similar results to those reported in high-quality trials; comparably, we did not find evidence to suggest that greater standardization of acupuncture practice would improve outcomes. Further research needs to be conducted exploring variability using a sample of acupuncturists with a broader range of practice styles, training and experience.

Dry needling strategies for musculoskeletal conditions: Do the number of needles and needle retention time matter? A narrative literature review

Acupuncture and dry needling are both minimally invasive procedures that use thin, filiform needles without injectate for the management of a variety of neuromusculoskeletal pain conditions. While the theoretical constructs underlying the use of acupuncture and dry needling are unique, both appear to have the ability to elicit biochemical, biomechanical, endocrinological and neurovascular changes associated with reductions in pain and disability. However, optimal treatment dosage has yet to be determined, and there is a lack of consistency in the literature on the number of needles that should be inserted and the needle retention time. Therefore, the purpose of this narrative review is to further explore the importance of these two variables. While trigger point dry needling advocates single needle insertions via repetitive, quick in-and-out pistoning, most acupuncture and dry needling clinical trials have incorporated multiple needles for five to 40 min. Notably and to date, using a single needle to repeatedly prick trigger points one at a time with fast-in and fast-out pistoning maneuvers has not yet been shown to produce significant and clinically meaningful long term improvements in pain and disability in a wide array of musculoskeletal conditions. Insertion of multiple needles for typically 20-30 min durations has been shown to produce larger treatment effect sizes and longer-lasting outcomes than brief, single-needle strategies. Moreover, the number of needles and needle retention time are two variables associated with treatment dosage and must be carefully matched with specific musculoskeletal conditions and the patient's goals.

The Effect of Patient Characteristics on Acupuncture Treatment Outcomes: An Individual Patient Data Meta-Analysis of 20,827 Chronic Pain Patients in Randomized Controlled Trials

OBJECTIVES

To optimally select chronic pain patients for different treatments, as it is of interest to identify patient characteristics that might moderate treatment effect. Our aim was to evaluate the impact of possible moderators on the effect of acupuncture treatment using a large data set.

METHODS

We used data from an individual patient data meta-analysis of high-quality randomized trials of acupuncture for chronic headache and migraine, osteoarthritis, and back, neck, and shoulder pain. Using meta-analytic trial-level and patient-level regression analyses, we explored the impact of 5 documented patient characteristics (patients' age at baseline, sex, pain duration, baseline pain severity and baseline psychological distress) on the effect of acupuncture.

RESULTS

A total of 39 trials met the inclusion criteria: 25 use sham-acupuncture controls (n = 7097) and 25 non-acupuncture controls (n = 16,041). Of the 5 patient characteristics analyzed, only baseline pain severity was found to potentially moderate the treatment effect of acupuncture, with patients reporting more severe pain at baseline experiencing more benefit from acupuncture compared to either sham-control or non-acupuncture control. Baseline psychological distress showed small treatment moderating effects, and results for sex were inconsistent. There was no strong evidence that age or duration of pain influenced the response to acupuncture.

DISCUSSION

Of 5 patient characteristics tested, we found only baseline severity of pain to potentially moderate the effect of acupuncture treatment. For clinical practice, the evidence from this analysis does not justify stratifying chronic pain patients into subgroups that should or should not receive acupuncture on the basis of these 5 characteristics. Future acupuncture trials should assess other potentially important effect moderators.

Which Interventions Enhance Pain Self-efficacy in People With Chronic Musculoskeletal Pain? A Systematic Review With Meta-analysis of Randomized Controlled Trials, Including Over 12 000 Participants

OBJECTIVE

To find out which interventions enhance pain self-efficacy in people with chronic musculoskeletal pain and to evaluate the reporting of interventions designed to enhance pain self-efficacy.

DESIGN

Intervention systematic review with meta-analysis.

LITERATURE SEARCH

PubMed, Embase, Scopus, PsycINFO, CINAHL, PEDro, and the Cochrane Central Register of Controlled Trials were searched from inception up to September 2019.

STUDY SELECTION CRITERIA

Randomized controlled trials evaluating pain self-efficacy as a primary or secondary outcome in chronic musculoskeletal pain.

DATA SYNTHESIS

We used the Cochrane risk of bias tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to evaluate the risk of bias and the certainty of the evidence, respectively.

RESULTS

Sixty randomized controlled trials were included (12 415 participants). There was a small effect of multicomponent, psychological, and exercise interventions improving pain self-efficacy at follow-ups of 0 to 3 months, a small effect of exercise and multicomponent interventions enhancing pain self-efficacy at follow-ups of 4 to 6 months, and a small effect of multicomponent interventions improving pain self-efficacy at follow-ups of 7 to 12 months. No interventions improved pain self-efficacy after 12 months. Self-management interventions did not improve pain self-efficacy at any follow-up time. Risk of bias, the nature of the control group, and the instrument to assess pain self-efficacy moderated the effects of psychological therapies at follow-ups of 7 to 12 months. The certainty of the evidence for all included interventions was low, due to serious risk of bias and indirectness. No trial reported the intervention in sufficient detail to allow full replication.

CONCLUSION

There was low-quality evidence of a small effect of multicomponent exercise and psychological interventions improving pain self-efficacy in people with chronic musculoskeletal pain. J Orthop Sports Phys Ther 2020;50(8):418-430. doi:10.2519/jospt.2020.9319.

Alexander Technique classes improve pain and performance factors in tertiary music students

BACKGROUND

Professional and student instrumental musicians experience high rates of playing-related pain (PR pain) and other playing-related musculoskeletal disorders (PRMDs). This significant occupational health risk signals an urgent need for preventive education at the college level. During tertiary studies however, music students may be more focused on musical skill development than health outcomes. Alexander Technique (AT) is reputed to be beneficial for factors relating to both PR pain and the improvement of performance quality in musicians, therefore AT training for music students could be relevant for prevention.

OBJECTIVES

To examine the effects of AT classes for tertiary music students on PR pain, associated risk factors for PR pain, and factors associated with improvements in music performance quality.

METHODS

Responses were collected from 23 volunteer music performance students at an Australian University who undertook weekly AT classes for one semester using a curriculum specifically designed for music students.

RESULTS

The majority of participants rated AT classes as beneficial for all factors, particularly reduction of PR pain, posture, ability to release excess muscle tension, improvements in instrumental technique, and improvements in performance level. Benefits to practice effectiveness and a reduction in non-playing-related pain, stress levels and performance anxiety were also reported.

CONCLUSIONS

Purpose-designed AT classes may contribute to the management of PR pain and pertinent risk factors in music students, thus further investigation of the potential role of AT classes in pain prevention programs is warranted. Reports of benefit across a range of performance-related skills strengthen relevance to music practice and performance.

Classic Chinese Acupuncture versus Different Types of Control Groups for the Treatment of Chronic Pain: Review of Randomized Controlled Trials (2000-2018)

Objective

To review the effectiveness of classic Chinese acupuncture in the treatment of chronic pain by comparing treatment groups with different types of control groups in accordance with the newly published guidelines for systematic reviews.

Methods

We searched EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials databases from 2000 to 2018. We included randomized controlled trials that included acupuncture as the sole treatment or as an adjunctive treatment for chronic pain. The outcome was pain intensity measured by the visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale, 11-point numeric rating scale (NRS), and other tools. Two researchers conducted the study selection, data extraction, and quality assessment processes independently. Disagreements were solved by discussion and reanalysis of the data. The quality of all included studies was evaluated using the CBNG (the Cochrane Back and Neck Group) and the STRICTA (Standards for Reporting Interventions in Controlled Trials of Acupuncture) checklists.

Results

Sixty-one studies were fully analyzed and ranked based on the newest STRICTA and CBNG standards. We found good evidence that receiving acupuncture is better than not receiving treatment or being placed on a waiting list and reasonable evidence that it is better than conventional or usual care. Limited evidence was found regarding placebo treatments that involve the expectation of needling (real or fake).

Conclusion

Sham acupuncture may not be appropriate as a control intervention for assessing the effectiveness of acupuncture. Acupuncture effectiveness in controlling chronic pain is still limited due to the low quality of the studies published.

The duration of acupuncture effects and its associated factors in chronic severe functional constipation: secondary analysis of a randomized controlled trial

BACKGROUND

Electroacupuncture (EA) has been shown to improve complete spontaneous bowel movements (CSBMs), but the duration of its effects remains unknown. The objective of this study was to explore the duration of acupuncture effects after treatment and its associated factors for chronic severe functional constipation (CSFC).

METHODS

This was a secondary analysis of a multicenter, randomized, sham-acupuncture (SA) controlled trial that included 1075 participants with CSFC. The primary outcome, the duration of acupuncture effects after treatment, was the number of weeks during the 12-week follow-up period that participants were to meet the weekly CSBM responder criteria. A weekly CSBM responder was defined as a participant who had at least three CSBMs for a given week and an increase from baseline of at least one CSBM for that same week. We performed a retrospective multivariate analysis to explore potential factors associated with sustained acupuncture effects.

RESULTS

The duration of acupuncture effects in the EA group (5.5 weeks) was significantly higher than the duration of SA effects in the SA group (2.2 weeks) with a between-group difference of 3.2 weeks (95% CI, 2.77-3.78; p < 0.001). A younger age and higher baseline CSBMs per week [regression coefficient (RC) -0.06, 95% confidence interval (CI) (-0.06 to -0.04); RC 2.43, 95% CI 1.78-3.60; respectively] were associated with longer durations of acupuncture effects.

CONCLUSIONS

EA had sustained post-treatment effects for CFSC. A significant association among a younger age, higher baseline CSBMs and sustained acupuncture effects was observed. Further research is needed to confirm the association.

Cochrane reviews on acupuncture therapy for pain: A snapshot of the current evidence

Cochrane is an international non-profit organization established in 1993 to produce and disseminate high quality and unbiased systematic reviews of evidence on health care interventions. At the forefront of systematic review methodology, Cochrane is generally accepted to be among the most carefully prepared and rigorous sources of systematic review evidence. There are numerous Cochrane reviews on nonpharmacologic interventions for pain and multiple Cochrane reviews evaluating acupuncture therapy in pain conditions. But how complete and up to date are those reviews relative to other rigorous systematic reviews with meta-analyses of acupuncture therapy for pain published in the literature? In this 'snapshot' overview, we found 22 relevant Cochrane reviews, some concluding that acupuncture therapy is probably useful for treating specific pain conditions. However, many of the conditions for which acupuncture is most commonly used are either not represented in Cochrane reviews or the existing Cochrane reviews are seriously outdated and do not reflect current evidence. This creates confusion with the risks of adverse effects and addiction liability associated with pain medications, the prevalence of chronic pain, the ongoing opioid epidemic and the need for evidence-based options for pain as part of comprehensive pain care. Clinicians and patients want clarification on safe and effective options to treat pain. Issues involving reviewed trials' inadequate use of sham comparators, of acupuncture as a complex intervention with interactive components and a shift in research focus from efficacy trials to real-world pragmatic trials are discussed in relation to updating Cochrane reviews of acupuncture therapy for pain.

What Is the Appropriate Acupuncture Treatment Schedule for Chronic Pain? Review and Analysis of Randomized Controlled Trials

Background

Acupuncture is widely used for the treatment of chronic pain. Different protocols of acupuncture practice exist and lack agreement on the optimal schedule of acupuncture treatment.

Objective

To review the appropriate acupuncture treatment schedule for chronic pain.

Methods

Embase, Pubmed, Cochrane Central Register of Controlled Trials, and reference lists were searched from 2009 to 2018 to identify randomized controlled trials of acupuncture for chronic pain conditions. We collected factors of treatment schedule (D, duration of each treatment session; N, number of treatment sessions; T, total duration of treatment in weeks) from each of the trials, and the linear regression analysis with real pain relief rate (both treatment and follow-up) was performed. Furthermore, we recommend the concept of “DOSE” and frequency (F) to evaluate the dose and frequency effect of acupuncture.

Results

Twenty-four trials with a total number of 3461 patients met the inclusion criteria. Of these, data from 23 studies were available for analysis. Firstly, the results showed that follow-up pain relief rate was decreased slightly with the increase of the duration of each session and DOSE (r=-0.3414 and r=-0.3246, respectively), but those two factors had no correlation with the pain relief rate after treatment. Secondly, it showed that either lower frequency with 2 sessions/week and higher frequency greater than 2 sessions/week or DOSE of 30 mins/week can achieve higher pain relief rate after treatment. Thirdly, we found the rate of pain relief remained at a high level greater than 20% up to 18 weeks after the treatment, and then it dropped sharply below 10% with the follow-up extended. A positive relationship was found between study score and pain relief both in treatment and follow-up (r=0.4654 and r=0.3046, respectively).

Conclusions

The effect of acupuncture varies greatly with the different schedules of acupuncture, so it is necessary to review and choose the appropriate schedule. Although the current work is based on a limited number of trials, the findings suggest that acupuncture has a dose and frequency effect presenting within a certain range, which would have considerable implications for the design and interpretation of clinical trials. More high-quality randomized controlled trials on acupuncture schedule research were needed for providing more definitive evidence.

Traditional Chinese Medicine Self-Care and Lifestyle Medicine Outside of Asia: A Systematic Literature Review

Background: Chinese medicine, when applied as a whole system of care, traditionally incorporates self-care techniques and patient understanding as key aspects of patient recovery and health maintenance. Objectives: This review aims to explore the literature to date on Traditional Chinese Medicine (TCM) self-care in settings outside of Asia, beyond the sole application of t'ai chi or qigong, to consider simple self-care techniques as health care interventions that may be generalized to a wider population. Design: AMED, CINAHL, EMBASE, PubMed, and MEDLINE databases were searched for articles from inception to July 2018. Studies were included, which were undertaken in settings outside of Asia and/or Asian communities, and were excluded if they solely examined t'ai chi or qigong. Results: Findings of the included studies (n = 37) were categorized into four key areas in relation to the TCM self-care component evaluated: self-acupressure, self-acupuncture, self-moxibustion, and the adoption of prescribed lifestyle, diet, and exercise advice based on a TCM diagnosis. The studies included randomized clinical trials, case studies, hospital audits, and qualitative evaluations. The studies assessed TCM self-care in relation to a wide range of health conditions, with the majority of studies concluding positive findings. Conclusion: This review draws attention to the potential role of TCM self-care techniques, in settings outside of Asia, beyond the sole practices of t'ai chi and qigong, as an adjunct to health maintenance and recovery. Only tentative conclusions can be drawn from the existing research, however, due to variability across studies in reporting transparency and the overall low number of studies retrieved. Further research is warranted.

Neck posture is influenced by anticipation of stepping

BACKGROUND

Postural deviations such as forward head posture (FHP) are associated with adverse health effects. The causes of these deviations are poorly understood. We hypothesized that anticipating target-directed movement could cause the head to get "ahead of" the body, interfering with optimal head/neck posture, and that the effect may be exacerbated by task difficulty and/or poor inhibitory control.

METHOD

We assessed posture in 45 healthy young adults standing quietly and when they anticipated walking to place a tray: in a simple condition and in conditions requiring that they bend low or balance an object on the tray. We defined FHP as neck angle relative to torso; we also measured head angle relative to neck and total neck length. We assessed inhibitory control using a Go/No-Go task, Stroop task, and Mindful Attention Awareness Scale (MAAS).

RESULTS

FHP increased when participants anticipated movement, particularly for more difficult movements. Worse Stroop performance and lower MAAS scores correlated with higher FHP. False alarms on the Go/No-Go task correlated with a more extended head relative to the neck and with shortening of the neck when anticipating movement.

CONCLUSIONS

Maintaining neutral posture may require inhibition of an impulse to put the head forward of the body when anticipating target-directed movement.

Effectiveness and Safety of Polydioxanone Thread-Embedding Acupuncture as an Adjunctive Therapy for Patients with Chronic Nonspecific Neck Pain: A Randomized Controlled Trial

OBJECTIVE

To evaluate the effectiveness and safety of treatment with thread-embedding acupuncture (TEA) using polydioxanone in addition to usual care for patients with chronic nonspecific neck pain (CNP) compared with treatment with usual care alone.

METHODS

A single-center, assessor-blinded, two-armed randomized controlled trial was performed. One hundred and six outpatients with CNP were randomly allocated into the TEA plus usual care (TU) group or the usual care (UC) group in a 1:1 ratio. TEA treatments in the neck region were provided once a week for 4 weeks, and usual care, as needed, was allowed. The primary outcome was the mean Neck Pain and Disability Scale (NPDS) score. Secondary outcomes included clinical relevance measured by using the clinically important difference (CID), pressure pain threshold (PPT), Hospital Anxiety and Depression Scale (HADS), EuroQol-5 Dimension (EQ-5D), and patient global impression of change (PGIC). Participants were assessed at baseline and at weeks 3, 5, and 9. Statistical analyses included analysis of covariance with baseline score as a covariate.

RESULTS

The TU group showed significant improvement in NPDS scores compared with the UC group (adjusted group difference, week 5: 13.74 [95% confidence interval: 7.57-19.90]; p < 0.0001 and week 9: 17.46 [11.15-23.76]; p < 0.0001). The proportion of patients with a decrease on the NPDS score of ≥11.5 points (minimal CID) was significantly higher in the TU group at weeks 5 and 9 than in the UC group. At weeks 5 and 9, significant differences were observed on the anxiety/depression subscale of HADS, EQ-5D, and PGIC between the two groups, but not the PPTs at three sites. Temporary stiffness was observed after TEA treatment, but no serious adverse events occurred.

CONCLUSIONS

The results suggest that polydioxanone TEA is a safe and clinically beneficial adjunctive treatment for patients with CNP.

Comparative effectiveness and economic evaluation of Chuna manual therapy for chronic neck pain: protocol for a multicenter randomized controlled trial

Background

Neck pain is a highly prevalent medical condition that incurs substantial social burden. Although manual therapy is widely used for treatment of neck pain, the body of evidence supporting its effectiveness and safety is not conclusive. The aim of this study is to examine the effect, safety, and cost-effectiveness of Chuna manual therapy, a traditional Korean manual therapy for treatment of various musculoskeletal complaints.

Methods/Design

This study is the protocol for a two-armed parallel, assessor-blinded, multicenter, randomized controlled trial. A total 108 patients with chronic neck pain (time to onset ≥ 3 months, numeric rating scale [NRS] of neck pain ≥ 5) will be recruited at five Korean medicine hospital sites. Participants will be allotted to one of two groups (n = 54, respectively): the Chuna manual therapy group, and the usual care (conventional physical therapy and medication treatment) group. Ten sessions of Chuna manual therapy or usual care will be administered twice a week for five weeks. Since the study design does not permit patient or physician blinding, the outcome assessor and statistician will be blinded. The primary outcome will be the visual analogue scale (VAS) of neck pain at 5 weeks after randomization. Secondary outcomes include the VAS of radiating arm pain, NRS of neck pain and radiating arm pain, Vernon-Mior neck disability index (NDI), Northwick Park neck pain questionnaire (NPQ), EuroQol-5 Dimension (EQ-5D), EQ-VAS, patient global impression of change (PGIC), economic evaluation, adverse effects, and drug consumption. Follow-up outcome assessments will be conducted at 3, 6, 9, and 12 months after randomization.

Discussion

This study will evaluate the comparative effectiveness of Chuna manual therapy and usual care on chronic neck pain. Adverse events, and costs and effectiveness (utility) data will be evaluated to assess safety and exploratory cost-effectiveness (economic evaluation). This study aims to provide evidence on the effectiveness, safety, and cost-effectiveness of Chuna manual therapy.

Is cupping therapy effective in patients with neck pain? A systematic review and meta-analysis

OBJECTIVES

Neck pain is a significant condition that is second only to depression as a cause of years lived with disability worldwide. Thus, identifying and understanding effective treatment modalities for neck pain is of heightened importance. This systematic review aimed to investigate the effects of cupping on neck pain from the current literature.

DESIGN

Systematic review and meta-analysis of randomised controlled trials (RCTs).

SETTING

Nine databases, including Chinese, Korean and Japanese databases, were searched for data up to January 2018 with no restrictions on publication language.

PARTICIPANTS

Patients with neck pain.

INTERVENTIONS

Cupping therapy as the sole or add-on intervention compared with no treatment or active controls.

PRIMARY AND SECONDARY OUTCOME MEASURES

Pain severity, functional disability and quality of life.

RESULTS

Eighteen RCTs were selected. Compared with the no intervention group, the cupping group exhibited significant reduction in pain (mean difference (MD) -2.42(95% CI -3.98 to -0.86)) and improvement in function (MD -4.34(95% CI -6.77 to -1.19)). Compared with the active control, the cupping group reported significant reduction in pain (p=0.0009) and significantly improved quality of life (p=0.001). The group that received control treatment with cupping therapy (add-on group) displayed significant pain reduction compared with the active control group (p=0.001). Of the 18 studies, only 8 reported occurrence of adverse events, which were mostly mild and temporary.

CONCLUSIONS

Cupping was found to reduce neck pain in patients compared with no intervention or active control groups, or as an add-on treatment. Depending on the type of control group, cupping was also associated with significant improvement in terms of function and quality of life; however, due to the low quality of evidence of the included studies, definitive conclusions could not be drawn from this review. Future well-designed studies are needed to substantiate the effectiveness of cupping on neck pain.

Preliminary evidence for feasibility, efficacy, and mechanisms of Alexander technique group classes for chronic neck pain

OBJECTIVES

To determine feasibility and potential of Alexander technique (AT) group classes for chronic neck pain and to assess changes in self-efficacy, posture, and neck muscle activity as potential mechanisms for pain reduction.

DESIGN

A single-group, multiple-baseline design, with two pre-tests to control for regression toward the mean, a post-test immediately after the intervention, and another post-test five weeks later to examine retention of benefits. Participants were predominately middle-aged; all had experienced neck pain for at least six months.

INTERVENTION

Participants attended ten one-hour group classes in AT, an embodied mindful approach that may reduce habitual overactivation of muscles, including superficial neck muscles, over five weeks.

OUTCOME MEASURES

(1) self-reports: Northwick Park Questionnaire (to assess neck pain and associated disability) and Pain Self-Efficacy Questionnaire; (2) superficial neck flexor activation and fatigue (assessed by electromyography and power spectral analysis) during the cranio-cervical flexion test; (3) posture during a video game task.

RESULTS

There were no significant changes in outcomes between pre-tests. All participants completed the intervention. After the intervention: (1) participants reported significantly reduced neck pain; (2) fatigue of the superficial neck flexors during the cranio-cervical flexion test was substantially lower; (3) posture was marginally more upright, as compared to the second pre-intervention values. Changes in pain, self-efficacy, and neck muscle fatigue were retained at the second post-test and tended to be correlated with one another.

CONCLUSIONS

Group AT classes may provide a cost-effective approach to reducing neck pain by teaching participants to decrease excessive habitual muscle contraction during everyday activity.

A systematic review of outcome measures utilised to assess self-management in clinical trials in patients with chronic pain

OBJECTIVES

The aim of this review was to identify, appraise and synthesise the outcome measures used to assess self-management in patients with chronic pain.

METHODS

Medline, Embase, CINAHL, PsycINFO, the Cochrane Library and Google Scholar were searched to identify quantitative measures used within randomised or non-randomised clinical trials to assess self-management in adults (≥18 years) with chronic pain.

RESULTS

25 RCTs published between 1998 and 2016 were included in this review. Studies included patients with chronic pain, hip/knee osteoarthritis, rheumatoid arthritis, chronic low back pain, fibromyalgia and chronic fatigue syndrome. Included studies utilised 14 different measures assessing a variety of constructs including self-efficacy (n = 19), coping (n = 4), empowerment (n = 2), pain attitude and management (n = 3), self-care (n = 1), role behaviour (n = 1) and multiple constructs of self-management (n = 1). The Chronic Pain Coping Inventory (CPCI) and Health Education Impact Questionnaire (heiQ) cover different self-management related constructs across the physical, mental and social health domains.

CONCLUSION

The review identified 14 measures used as proxy measure to assess self-management in patients with chronic pain. These measures have good content and construct validity, and internal consistency. However additional research is required to develop their reliability, responsiveness and interpretability.

PRACTICE IMPLICATIONS

Multi-constructs measures (CPCI, heiQ) are suitable for assessing self-management.

Cortical remodeling after electroacupuncture therapy in peripheral nerve repairing model

Electroacupuncture (EA) is an alternative therapy for peripheral nerve injury (PNI). The treatment relies on post-therapeutic effect rather than real-time effect. We utilized fMRI to clarify the resting-state alteration caused by sustained effect of EA on peripheral nerve repairing model. Twenty-four rats were divided equally into three groups: normal group, model group and intervention group. Rats of the model and intervention group underwent sciatic nerve transection and direct anastomosis. EA intervention at ST-36 and GB-30 was conducted continuously for 4 months on the intervention group. Behavioral assessments and fMRI were performed 1 month and 4 months after surgery. Intervention group showed significant improvement on the gait parameters max contact mean intensity (MCMI) and thermal withdrawal latency (TWL) than model group. EA-related sustained effects of amplitude of low frequency fluctuations (ALFF) could be described as a remolding pattern of somatosensory area and sensorimotor integration regions which presented higher ALFF in the contralateral hemisphere and lower in the ipsilateral hemisphere than model group. Interhemispheric functional connectivity (FC) analysis showed a significantly lower FC after EA therapy between the largest significantly different clusters in bilateral somatosensory cortices than the model group 4 months after surgery(p < 0.05). And the model group presented significantly higher FC than the normal group at both two time-points (p < 0.01). The sustained effect of EA on peripheral nerve repairing rats appeared to induce both regional and extensive neuroplasticity in bilateral hemispheres. We proposed that such EA-related effect was a reverse of maladaptive plasticity caused by PNI.

Self-efficacy and embodiment associated with Alexander Technique lessons or with acupuncture sessions: A longitudinal qualitative sub-study within the ATLAS trial

Background and purpose

A large randomised controlled trial found that the provision of either Alexander Technique lessons or acupuncture, for those with chronic neck pain, resulted in significantly increased self-efficacy when compared with usual care alone. In turn, enhanced self-efficacy was associated with significant reductions in neck pain at 6 and 12 months. In this analysis we explore the perspectives of participants within the trial, with the aim of gaining a better understanding of how these interventions had an impact.

Methods

We used a longitudinal qualitative approach; in-depth interviews, informed by a topic guide, were conducted with a sample of the trial population. Participants were interviewed twice: at around six months (n = 30) and twelve months (n = 26) after trial entry. Analysis was guided by the principles of grounded theory, and key themes were developed.

Results

Five key themes emerged: pre-trial experiences of biomedical treatment against which subsequent interventions were compared; emergence of tangible benefits from the interventions; factors that contributed to the observed benefits, notably growing self-care and self-efficacy; a developing sense of embodiment as an integral part of the transformative process; and contribution of these factors to sustaining benefits over the longer term.

Conclusions

In-depth interviews revealed a rich array of experiences. They gave insight into the positive impact of the interventions on development of self-care, self-efficacy and embodiment. These findings complement the quantitative trial data, providing a more nuanced understanding of the factors that underpin the previously quantified improvement in self-efficacy and its association with longer-term reductions in pain.

A Longitudinal Mapping Study on Cortical Plasticity of Peripheral Nerve Injury Treated by Direct Anastomosis and Electroacupuncture in Rats

OBJECTIVE

We used functional magnetic resonance imaging to provide a longitudinal description of cortical plasticity caused by electroacupuncture (EA) of sciatic nerve transection and direct anastomosis in rats.

METHODS

Sixteen rats in a sciatic nerve transection and direct anastomosis model were randomly divided into intervention and control groups. EA intervention in the position of ST-36, GB-30 was conducted continuously for 4 months in the intervention group. Functional magnetic resonance imaging and gait assessment were performed every month after intervention.

RESULTS

The somatosensory area was more activated in the first 2 months and then deactivated in the rest 2 months when EA was applied. The pain-related areas had the same activation pattern as the somatosensory area. The limbic/paralimbic areas fluctuated more during the EA intervention, which was not constantly activated or deactivated as previous studies reported. We attributed such changes in somatosensory and pain-related areas to the gradual reduction of sensory afferentation. The alterations in limbic/paralimbic system might be associated with the confrontation between the upregulating effect of paresthesia or pain and the downregulating effect of EA intervention through the autonomic nerve system. The gait analysis showed significantly higher maximum contact mean intensity in the intervention group.

CONCLUSIONS

The alterations in the brain brought about by the long-term therapeutic effect of EA could be described as a synchronized activation pattern in the somatosensory and pain-related areas and a fluctuating pattern in the limbic/paralimbic system.

Evidence-Based Nonpharmacologic Strategies for Comprehensive Pain Care: The Consortium Pain Task Force White Paper

Medical pain management is in crisis; from the pervasiveness of pain to inadequate pain treatment, from the escalation of prescription opioids to an epidemic in addiction, diversion and overdose deaths. The rising costs of pain care and managing adverse effects of that care have prompted action from state and federal agencies including the DOD, VHA, NIH, FDA and CDC. There is pressure for pain medicine to shift away from reliance on opioids, ineffective procedures and surgeries toward comprehensive pain management that includes evidence-based nonpharmacologic options. This White Paper details the historical context and magnitude of the current pain problem including individual, social and economic impacts as well as the challenges of pain management for patients and a healthcare workforce engaging prevalent strategies not entirely based in current evidence. Detailed here is the evidence-base for nonpharmacologic therapies effective in postsurgical pain with opioid sparing, acute non-surgical pain, cancer pain and chronic pain. Therapies reviewed include acupuncture therapy, massage therapy, osteopathic and chiropractic manipulation, meditative movement therapies Tai chi and yoga, mind body behavioral interventions, dietary components and self-care/self-efficacy strategies. Transforming the system of pain care to a responsive comprehensive model necessitates that options for treatment and collaborative care must be evidence-based and include effective nonpharmacologic strategies that have the advantage of reduced risks of adverse events and addiction liability. The evidence demands a call to action to increase awareness of effective nonpharmacologic treatments for pain, to train healthcare practitioners and administrators in the evidence base of effective nonpharmacologic practice, to advocate for policy initiatives that remedy system and reimbursement barriers to evidence-informed comprehensive pain care, and to promote ongoing research and dissemination of the role of effective nonpharmacologic treatments in pain, focused on the short- and long-term therapeutic and economic impact of comprehensive care practices.

Thread embedding acupuncture for musculoskeletal pain: a systematic review and meta-analysis protocol

INTRODUCTION

Thread embedding acupuncture (TEA) is a special type of acupuncture that inserts certain medical threads (eg, catgut or polydioxanone) into subcutaneous tissue or muscles at specific points. Although TEA has been widely used for the treatment of musculoskeletal pain in Korea, China and Taiwan, evidence regarding its efficacy is lacking. The aim of this protocol is to evaluate the effectiveness and safety of TEA in the treatment of musculoskeletal pain, by conducting a systematic review and meta-analysis.

METHODS AND ANALYSIS

The following 16 databases will be searched from their inception to 14 May 2017: MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE, the Cumulative Index to Nursing and Allied Health Literature, the Allied and Complementary Medicine Database, three Chinese database (China National Knowledge Infrastructure, the Chongqing VIP Chinese Science and Technology Periodical Database and the Wanfang database) and eight Korean databases (Korean Medical Database, Korean Association of Medical Journal Editors, Korean Studies Information Service System, Korean National Assembly Digital Library, National Digital Science Library, Oriental Medicine Advanced Searching Integrated System, 'Database Periodical Information Academic and Korean Traditional Knowledge Portal'). The WHO International Clinical Trials Registry Platform will also be searched to retrieve the recently completed studies.All randomised controlled studies in which TEA was used on specific points for the treatment of musculoskeletal pain will be included and no restrictions on language will be applied. The risk of bias of each study will be evaluated by the Cochrane risk of bias tool.Mean difference or standardised mean difference for continuous data and risk ratio for dichotomous data will be calculated with 95% CIs using a random effects model or a fixed effects model. Additional subgroup and sensitivity analyses will be conducted according to a predefined protocol.

ETHICS AND DISSEMINATION

No ethical issues are predicted. The systematic review will be published in a peer-reviewed journal or conference presentation. These findings will summarise the current evidence of TEA for the treatment of musculoskeletal pain and may provide guidance for clinicians and patients to select TEA for musculoskeletal pain.

Self-efficacy and self-care-related outcomes following Alexander Technique lessons for people with chronic neck pain in the ATLAS randomised, controlled trial

Introduction

ATLAS was a pragmatic randomised (1:1:1 ratio), controlled trial recruiting patients with chronic neck pain (N = 517) and evaluating one-to-one Alexander Technique lessons, or acupuncture, each plus usual care, compared with usual care alone. The primary outcome (12-month Northwick Park Neck Pain Questionnaire [NPQ]) demonstrated significant and clinically meaningful reductions in neck pain and associated disability for both interventions compared with usual care alone. Here we describe pre-specified, self-efficacy and other self-care-related outcomes for the Alexander group compared with usual care.

Methods

Participants reported on 11 self-efficacy/self-care-related outcome measures at 6 and 12 months. Linear or logistic regression models evaluated changes in parameters and impact on NPQ. Alexander teachers reported on lesson content.

Results

Lesson content reflected standard UK practice. The Alexander group (n = 172) reported significantly greater improvements, compared with usual care alone (n = 172), in most of the self-efficacy/self-care measures (9/11 measures at 6 months, and 8/11 at 12 months), including the ability to reduce pain in daily life. At 6 months, 81% (106/131) of Alexander participants reported significant improvement in the way they lived and cared for themselves (versus 23% for usual care), increasing to 87% (117/135) at 12 months (usual care: 25%). NPQ scores at both 6 and 12 months were related to improvement in self-efficacy and ability to reduce pain during daily life.

Conclusions

Alexander Technique lessons led to long-term improvements in the way participants lived their daily lives and managed their neck pain. Alexander lessons promote self-efficacy and self-care, with consequent reductions in chronic neck pain.

An economic evaluation of Alexander Technique lessons or acupuncture sessions for patients with chronic neck pain: A randomized trial (ATLAS)

Objectives

To assess the cost-effectiveness of acupuncture and usual care, and Alexander Technique lessons and usual care, compared with usual GP care alone for chronic neck pain patients.

Methods

An economic evaluation was undertaken alongside the ATLAS trial, taking both NHS and wider societal viewpoints. Participants were offered up to twelve acupuncture sessions or twenty Alexander lessons (equivalent overall contact time). Costs were in pounds sterling. Effectiveness was measured using the generic EQ-5D to calculate quality adjusted life years (QALYs), as well as using a specific neck pain measure–the Northwick Park Neck Pain Questionnaire (NPQ).

Results

In the base case analysis, incremental QALY gains were 0.032 and 0.025 in the acupuncture and Alexander groups, respectively, in comparison to usual GP care, indicating moderate health benefits for both interventions. Incremental costs were £451 for acupuncture and £667 for Alexander, mainly driven by intervention costs. Acupuncture was likely to be cost-effective (ICER = £18,767/QALY bootstrapped 95% CI £4,426 to £74,562) and was robust to most sensitivity analyses. Alexander lessons were not cost-effective at the lower NICE threshold of £20,000/QALY (£25,101/QALY bootstrapped 95% CI -£150,208 to £248,697) but may be at £30,000/QALY, however, there was considerable statistical uncertainty in all tested scenarios.

Conclusions

In comparison with usual care, acupuncture is likely to be cost-effective for chronic neck pain, whereas, largely due to higher intervention costs, Alexander lessons are unlikely to be cost-effective. However, there were high levels of missing data and further research is needed to assess the long-term cost-effectiveness of these interventions.

Acupuncture for Chronic Pain: Update of an Individual Patient Data Meta-Analysis

Despite wide use in clinical practice, acupuncture remains a controversial treatment for chronic pain. Our objective was to update an individual patient data meta-analysis to determine the effect size of acupuncture for 4 chronic pain conditions. We searched MEDLINE and the Cochrane Central Registry of Controlled Trials randomized trials published up until December 31, 2015. We included randomized trials of acupuncture needling versus either sham acupuncture or no acupuncture control for nonspecific musculoskeletal pain, osteoarthritis, chronic headache, or shoulder pain. Trials were only included if allocation concealment was unambiguously determined to be adequate. Raw data were obtained from study authors and entered into an individual patient data meta-analysis. The main outcome measures were pain and function. An additional 13 trials were identified, with data received for a total of 20,827 patients from 39 trials. Acupuncture was superior to sham as well as no acupuncture control for each pain condition (all P < .001) with differences between groups close to .5 SDs compared with no acupuncture control and close to .2 SDs compared with sham. We also found clear evidence that the effects of acupuncture persist over time with only a small decrease, approximately 15%, in treatment effect at 1 year. In secondary analyses, we found no obvious association between trial outcome and characteristics of acupuncture treatment, but effect sizes of acupuncture were associated with the type of control group, with smaller effects sizes for sham controlled trials that used a penetrating needle for sham, and for trials that had high intensity of intervention in the control arm. We conclude that acupuncture is effective for the treatment of chronic pain, with treatment effects persisting over time. Although factors in addition to the specific effects of needling at correct acupuncture point locations are important contributors to the treatment effect, decreases in pain after acupuncture cannot be explained solely in terms of placebo effects. Variations in the effect size of acupuncture in different trials are driven predominantly by differences in treatments received by the control group rather than by differences in the characteristics of acupuncture treatment.

PERSPECTIVE

Acupuncture is effective for the treatment of chronic musculoskeletal, headache, and osteoarthritis pain. Treatment effects of acupuncture persist over time and cannot be explained solely in terms of placebo effects. Referral for a course of acupuncture treatment is a reasonable option for a patient with chronic pain.

Acupuncture for neuropathic pain in adults

BACKGROUND

Neuropathic pain may be caused by nerve damage, and is often followed by changes to the central nervous system. Uncertainty remains regarding the effectiveness and safety of acupuncture treatments for neuropathic pain, despite a number of clinical trials being undertaken.

OBJECTIVES

To assess the analgesic efficacy and adverse events of acupuncture treatments for chronic neuropathic pain in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four Chinese databases, ClinicalTrials.gov and World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 14 February 2017. We also cross checked the reference lists of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) with treatment duration of eight weeks or longer comparing acupuncture (either given alone or in combination with other therapies) with sham acupuncture, other active therapies, or treatment as usual, for neuropathic pain in adults. We searched for studies of acupuncture based on needle insertion and stimulation of somatic tissues for therapeutic purposes, and we excluded other methods of stimulating acupuncture points without needle insertion. We searched for studies of manual acupuncture, electroacupuncture or other acupuncture techniques used in clinical practice (such as warm needling, fire needling, etc).

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcomes were pain intensity and pain relief. The secondary outcomes were any pain-related outcome indicating some improvement, withdrawals, participants experiencing any adverse event, serious adverse events and quality of life. For dichotomous outcomes, we calculated risk ratio (RR) with 95% confidence intervals (CI), and for continuous outcomes we calculated the mean difference (MD) with 95% CI. We also calculated number needed to treat for an additional beneficial outcome (NNTB) where possible. We combined all data using a random-effects model and assessed the quality of evidence using GRADE to generate 'Summary of findings' tables.

MAIN RESULTS

We included six studies involving 462 participants with chronic peripheral neuropathic pain (442 completers (251 male), mean ages 52 to 63 years). The included studies recruited 403 participants from China and 59 from the UK. Most studies included a small sample size (fewer than 50 participants per treatment arm) and all studies were at high risk of bias for blinding of participants and personnel. Most studies had unclear risk of bias for sequence generation (four out of six studies), allocation concealment (five out of six) and selective reporting (all included studies). All studies investigated manual acupuncture, and we did not identify any study comparing acupuncture with treatment as usual, nor any study investigating other acupuncture techniques (such as electroacupuncture, warm needling, fire needling).One study compared acupuncture with sham acupuncture. We are uncertain if there is any difference between the two interventions on reducing pain intensity (n = 45; MD -0.4, 95% CI -1.83 to 1.03, very low-quality evidence), and neither group achieved 'no worse than mild pain' (visual analogue scale (VAS, 0-10) average score was 5.8 and 6.2 respectively in the acupuncture and sham acupuncture groups, where 0 = no pain). There was limited data on quality of life, which showed no clear difference between groups. Evidence was not available on pain relief, adverse events or other pre-defined secondary outcomes for this comparison.Three studies compared acupuncture alone versus other therapies (mecobalamin combined with nimodipine, and inositol). Acupuncture may reduce the risk of 'no clinical response' to pain than other therapies (n = 209; RR 0.25, 95% CI 0.12 to 0.51), however, evidence was not available for pain intensity, pain relief, adverse events or any of the other secondary outcomes.Two studies compared acupuncture combined with other active therapies (mecobalamin, and Xiaoke bitong capsule) versus other active therapies used alone. We found that the acupuncture combination group had a lower VAS score for pain intensity (n = 104; MD -1.02, 95% CI -1.09 to -0.95) and improved quality of life (n = 104; MD -2.19, 95% CI -2.39 to -1.99), than those receiving other therapy alone. However, the average VAS score of the acupuncture and control groups was 3.23 and 4.25 respectively, indicating neither group achieved 'no worse than mild pain'. Furthermore, this evidence was from a single study with high risk of bias and a very small sample size. There was no evidence on pain relief and we identified no clear differences between groups on other parameters, including 'no clinical response' to pain and withdrawals. There was no evidence on adverse events.The overall quality of evidence is very low due to study limitations (high risk of performance, detection, and attrition bias, and high risk of bias confounded by small study size) or imprecision. We have limited confidence in the effect estimate and the true effect is likely to be substantially different from the estimated effect.

AUTHORS' CONCLUSIONS

Due to the limited data available, there is insufficient evidence to support or refute the use of acupuncture for neuropathic pain in general, or for any specific neuropathic pain condition when compared with sham acupuncture or other active therapies. Five studies are still ongoing and seven studies are awaiting classification due to the unclear treatment duration, and the results of these studies may influence the current findings.

Current practice and usual care of major cervical disorders in Korea: A cross-sectional study of Korean health insurance review and assessment service national patient sample data

Neck pain is a highly common condition and is the 4th major cause of years lived with disability. Previous literature has focused on the effect of specific treatments, and observations of actual practice are lacking to date. This study examined Korean health insurance review and assessment service (HIRA) claims data to the aim of assessing prevalence and comparing current medical practice and costs of cervical disorders in Korea.Current practice trends were determined through assessment of prevalence, total expenses, per-patient expense, average days in care, average days of visits, sociodemographic characteristics, distribution of medical costs, and frequency of treatment types of high frequency cervical disorders (cervical sprain/strain, cervical intervertebral disc displacement [IDD], and cervicalgia).Although the number of cervical IDD patients was few, total expenses, per-patient expense, average days in care, and average days of visits were highest. The proportion of women was higher than men in all 3 groups with highest prevalence in the ≥50s middle-aged population for IDD compared to sprain/strain. Primary care settings were commonly used for ambulatory care, of which approximately 70% chose orthopedic specialist treatment. In analysis of medical expenditure distribution, costs of visit (consultation) (22%-34%) and physical therapy (14%-16%) were in the top 3 for all 3 disorders. Although heat and electrical therapies were the most frequently used physical therapies, traction use was high in the cervical IDD group. In nonnarcotics, aceclofenac and diclofenac were the most commonly used NSAIDs, and pethidine was their counterpart in narcotics.This study investigated practice trends and cost distribution of treatment regimens for major cervical disorders, providing current usage patterns to healthcare policy decision makers, and the detailed treatment reports are expected to be of use to clinicians and researchers in understanding current usual care.

Effects of Implementing the Alexander Technique on Enjoying the Sense of Motherhood in the Postpartum Period

BACKGROUND

The broad concept of maternal well-being includes psychological concepts, social aspects, and aspects of becoming a mother. The present study aimed to investigate the effects of implementing the Alexander technique on enjoying the sense of motherhood.

MATERIALS AND METHODS

This study was a clinical trial conducted in two phases. In the first phase, using the exploratory and confirmatory factor analysis, 226 mothers were asked to undergo a scale test of enjoying the sense of motherhood after childbirth. In the second phase, 88 pregnant women were divided into two experimental groups. The data collection tool was a researcher-made questionnaire about enjoying the sense of motherhood. Independent samples t-test, Mann-Whitney test, Chi-square test, Fisher's exact test, analysis of variance test, Box test, and Levine test were used to analyze the data.

RESULTS

Results of this study showed that the mean scores of the constructs of enjoying pregnancy (P > 0.001), motherhood, and child care satisfaction (P > 0.001) in the experimental group were significantly higher than the control group. Moreover, the construct of trusting their own abilities to cope with maternal duties (P > 0.01) did not show significant differences between the two groups.

CONCLUSIONS

The findings indicated that the Alexander technique can promote mothers' psychological well-being and their pleasure of becoming a mother and the related constructs. Results also revealed that using this technique, educating and recommending pregnant women to use this technique will be beneficial.

Interventional Pain Management in Multidisciplinary Chronic Pain Clinics: A Prospective Multicenter Cohort Study with One-Year Follow-Up

Background

Interventional Pain Management (IPM) is performed in multidisciplinary chronic pain clinics (MCPC), including a range of invasive techniques to diagnose and treat chronic pain (CP) conditions. Current patterns of use of those techniques in MCPC have not yet been reported.

Objective

We aimed to describe quantitatively and qualitatively the use of IPM and other therapeutic procedures performed on-site at four Portuguese MCPC.

Methods

A prospective cohort study with one-year follow-up was performed in adult patients. A structured case report form was systematically completed at baseline and six and 12 months.

Results

Among 808 patients referred to the MCPC, 17.2% had been prescribed IPM. Patients with IPM were on average younger and had longer CP duration and lower levels of maximum pain and pain interference/disability. The three main diagnoses were low back pain (n = 28), postoperative CP, and knee pain (n = 16 each). From 195 IPM prescribed, nerve blocks (n = 108), radiofrequency (n = 31), and viscosupplementation (n = 22) were the most prevalent. Some IPM techniques were only available in few MCPC. One MCPC did not provide IPM.

Conclusions

IPM are seldom prescribed in Portuguese MCPC. Further studies on IPM safety and effectiveness are necessary for clear understanding the role of these techniques in CP management.

Detection of peripheral and central sensitisation at acupoints in patients with unilateral shoulder pain in Beijing: a cross-sectional matched case-control study

OBJECTIVE

To investigate the pattern of experimental pain responses at acupoints in patients with unilateral shoulder pain.

DESIGN

A cross-sectional matched study.

SETTING

Acupuncture and Moxibustion Department, Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University.

PARTICIPANTS

Volunteer samples of 60 participants (30 patients with unilateral shoulder pain, 30 healthy controls).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Pressure pain thresholds (PPTs) were measured at four acupoints-namely, Tianzong (SI 11), Jianliao (SJ 14), Jianyu (LI 15) and Jianzhen (SI 9), on the painful/non-painful side in patients with unilateral shoulder pain or healthy controls, respectively. The correlations between the Peripheral Sensitisation Index (PSI) and Central Sensitisation Index (CSI) were compared.

RESULTS

Analysis showed significantly lower PPT values at acupoints on the painful side compared with the non-painful side in patients with shoulder pain (p<0.025). Meanwhile, PPTs on the non-painful side of these patients were lower than those on the ipsilateral side of healthy controls (p<0.025). No significant differences in PPT values were found between the non-acupoint of the painful/non-painful side in patients with shoulder pain and the ipsilateral side of healthy controls (p>0.05). Additionally, it was observed that the pressure pain assessment acupoints have a strong association with PSI and CSI; three acupoints, in particular, SJ 14, LI 15 and SI 9, showed a correlation with PSI and CSI.

CONCLUSION

The results suggest the presence of peripheral and central sensitisation at acupoints in participants with unilateral shoulder pain. There exists an obvious relationship among the three acupoints SJ 14, LI 15 and SI 9, which are usually chosen to treat shoulder pain. The results provide evidence for the selection of acupoints to treat shoulder pain by acupuncture.

Lifestyle Advice and Self-Care Integral to Acupuncture Treatment for Patients with Chronic Neck Pain: Secondary Analysis of Outcomes Within a Randomized Controlled Trial

Background: Lifestyle advice is widely considered as an integral component of acupuncture treatment. However, it is unclear whether lifestyle advice and related self-care are important for sustaining benefit over the longer term. In a novel secondary analysis of trial data, this paper explores the nature and impact of acupuncture-related diagnosis, and associated lifestyle advice and self-care, in patients with chronic neck pain.

Design: In a three-arm, randomized, controlled multicenter trial with 12 months of follow-up, a total of 517 patients with chronic neck pain were randomized in equal proportions to acupuncture, Alexander technique, or usual care alone.

Methods: For each acupuncture patient, practitioners reported treatment components that included an acupuncture-related diagnosis and provision of associated lifestyle advice. Patients reported at baseline, 3, 6, and 12 months on variables related to treatment, which included aspects of self-care, self-efficacy, and lifestyle advice acted upon, as well as pain and disability scores. Congruence between practitioner advice and patient take-up was assessed using chi-squared test. Impact of lifestyle advice and self-efficacy on outcome was evaluated using regression models.

Results: Among patients randomized to acupuncture, the most common diagnostic framework involved the Zang–Fu syndromes for 139/160 (87%) patients. Lifestyle advice was provided by practitioners to 134/160 (84%) of patients, most commonly related to exercise, relaxation, diet, rest, and work. Significant congruence with patient take-up was found for diet, rest, and work. Moreover, patients in the acupuncture group improved their ability to use what they had learnt and increased their self-efficacy. In turn, these characteristics were associated with significant reductions in pain and disability scores at 12 months.

Conclusion: Acupuncture-related lifestyle advice helped patients improve the way they live and care for themselves and enhanced self-efficacy and ability to use what they had learnt. These changes were associated with reductions in pain and disability at 12 months.

Older adult Alexander Technique practitioners walk differently than healthy age-matched controls

The Alexander Technique (AT) seeks to eliminate harmful patterns of tension that interfere with the control of posture and movement and in doing so, it may serve as a viable intervention method for increasing gait efficacy in older adults. The purpose of this study was to compare the comfortable pace gait kinematics of older AT practitioners with those of healthy, age-matched controls. Participants were six licensed AT practitioners and seven healthy age-matched controls between the ages of 61-76. During the stance phase, AT participants exhibited significantly greater ankle stance range of motion (ROM) and plantar flexion at toe off, as well as lower ROM of the trunk and head compared to controls. During the swing phase, the AT practitioners had significantly increased hip and knee flexion and a trend toward significantly increased dorsiflexion. The findings suggest that the older AT practitioners walked with gait patterns more similar to those found in the literature for younger adults. These promising results highlight the need for further research to assess the AT's potential role as an intervention method for ameliorating the deleterious changes in gait that occur with aging.

Reductions in co-contraction following neuromuscular re-education in people with knee osteoarthritis

Background

Both increased knee muscle co-contraction and alterations in central pain processing have been suggested to play a role in knee osteoarthritis pain. However, current interventions do not target either of these mechanisms. The Alexander Technique provides neuromuscular re-education and may also influence anticipation of pain. This study therefore sought to investigate the potential clinical effectiveness of the AT intervention in the management of knee osteoarthritis and also to identify a possible mechanism of action.

Methods

A cohort of 21 participants with confirmed knee osteoarthritis were given 20 lessons of instruction in the Alexander Technique. In addition to clinical outcomes EMG data, quantifying knee muscle co-contraction and EEG data, characterising brain activity during anticipation of pain, were collected. All data were compared between baseline and post-intervention time points with a further 15-month clinical follow up. In addition, biomechanical data were collected from a healthy control group and compared with the data from the osteoarthritis subjects.

Results

Following AT instruction the mean WOMAC pain score reduced by 56 % from 9.6 to 4.2 (P < 0.01) and this reduction was maintained at 15 month follow up. There was a clear decrease in medial co-contraction at the end of the intervention, towards the levels observed in the healthy control group, both during a pre-contact phase of gait (p < 0.05) and during early stance (p < 0.01). However, no changes in pain-anticipatory brain activity were observed. Interestingly, decreases in WOMAC pain were associated with reductions in medial co-contraction during the pre-contact phase of gait.

Conclusions

This is the first study to investigate the potential effectiveness of an intervention aimed at increasing awareness of muscle behaviour in the clinical management of knee osteoarthritis. These data suggest a complex relationship between muscle contraction, joint loading and pain and support the idea that excessive muscle co-contraction may be a maladaptive response in this patient group. Furthermore, these data provide evidence that, if the activation of certain muscles can be reduced during gait, this may lead to positive long-term clinical outcomes. This finding challenges clinical management models of knee osteoarthritis which focus primarily on muscle strengthening.
