Comparison of CPG's for the diagnosis, prognosis and management of non-specific neck pain: a systematic review

Nonpharmacological Spine Pain Management in Clinical Practice Guidelines: A Systematic Review Using AGREE II and AGREE-REX Tools

OBJECTIVE: To summarize the content and critically appraise the quality and applicability of recent clinical practice guidelines (CPGs) for nonpharmacological, nonsurgical management of spine pain. DESIGN: Systematic review of CPGs. LITERATURE SEARCH: Six databases and seven guideline clearinghouses. STUDY SELECTION CRITERIA: Included de novo CPGs for nonpharmacological, nonsurgical management of spine pain designed for any primary health care providers, published in English, Arabic, French, or traditional Chinese within the past 12 years. DATA SYNTHESIS: Five reviewers independently appraised the guidelines using AGREE II and AGREE-REX. Interrater agreements were calculated for each domain and the total score of these tools using the intraclass correlation coefficient (2, 1) with absolute agreement. RESULTS: We included 30 CPGs, primarily (90%) developed in Western countries, which contained 404 recommendations. High-quality CPGs consistently recommended exercise therapy and multimodal care, encompassing a combination of exercises, mobilization/manipulation, education, alternative medicine, and cognitive-behavioral treatments. Generally, CPGs did not recommend assistive (eg, corsets and orthosis) devices or electro/thermotherapies (eg, therapeutic ultrasound and transcutaneous electrical nerve stimulation). Approximately half of the CPGs demonstrated good methodological quality according to AGREE II, whereas the rest were of poor quality. On the AGREE-REX assessment, one third of the recommendations were of excellent quality. CONCLUSION: Although recent guidelines frequently recommended exercise therapy and multimodal care for the management of spine pain, their recommendations often overlooked demographics and comorbidities. Despite methodological improvements, most CPGs lacked simple clinical applicability and considerations of knowledge users' values. J Orthop Sports Phys Ther 2025;55(1):1-14.

Patterns of initial treatment and subsequent care escalation among medicare beneficiaries with neck pain: a retrospective cohort study

PURPOSE

To compare long-term care escalation encounters among three care patterns for new episodes of neck pain among Medicare beneficiaries.

METHODS

We examined Medicare claims spanning a four-year period for beneficiaries with new episodes of neck pain beginning in 2019. All patients were continuously enrolled under Medicare parts A, B, and D and aged 65-99 years. We calculated the cumulative frequency and propensity- weighted rate ratios for escalated care encounters across three distinct, index-visit related neck pain treatment cohorts: 1) Spinal manipulative therapy; 2) Primary care without prescription analgesics within 7 days; 3) Primary care with prescription analgesics within 7 days.

RESULTS

When compared to the primary care without analgesics cohort, the spinal manipulative therapy cohort was associated with a 64% lower rate (RR 0.36, 95% CI 0.35,0.37) for long-term care escalation encounters, while the primary care with prescription analgesics cohort was associated with an 8% higher rate (RR 1.08; 95% CI 1.05,1.10).

CONCLUSION

Initial spinal manipulative therapy was associated with a significant reduction in downstream care escalation encounters among Medicare beneficiaries with new episodes of neck pain. Our study contributes to a growing body of evidence supporting the integration of non-pharmacological care strategies for neck pain management.

An overview of systematic reviews investigating clinical features for diagnosing neck pain and its associated disorders

BACKGROUND

Neck pain is a common condition that is often difficult to diagnose. Previous literature has investigated diagnostic accuracy of examination measures, but the strength and clinical applicability are limited. This overview of systematic reviews aimed to investigate clinical features for diagnosing neck pain and its associated disorders.

METHODS

An overview of systematic reviews was conducted searching four electronic databases for systematic reviews evaluating diagnostic criteria for neck pain. Quality and risk of bias were assessed using the AMSTAR 2 and ROBIS. Clinical features for neck pain were investigated for diagnostic utility.

RESULTS

Twenty-seven systematic reviews were included. Hand radiculopathy and numbness have good specificities (0.89-0.92) for facet and uncinate joint hypertrophy. For facet-related dysfunction, the extension rotation test (ERT) and manual assessment have good sensitivities and moderate-good specificities. Positive ERT combined with positive manual assessment findings (+LR = 4.71; Sp = 0.83) improves diagnostic accuracy compared to positive ERT alone (+LR = 2.01; Sp = 0.59). Canadian C-spine Rules and Nexus criteria have excellent validity in screening for cervical fracture or instability. Imaging appears to have validity in diagnosing ligamentous disruption or fractures but lacks clarity on predicting future neck pain. Increased fatty infiltrates have been found with whiplash-associated disorders and mechanical neck pain.

CONCLUSIONS

This review found limited indicators providing strong diagnostic utility for diagnosing neck pain. Strength of recommendations are limited by heterogeneous outcomes, methodology, and classification systems. Future research should investigate new differential diagnostic criteria for specific structures contributing to neck pain.

Redesigning the Care of Musculoskeletal Conditions With Lifestyle Medicine

Value-based health care has been accelerated by alternative payment models and has catalyzed the redesign of care delivery across the nation. Lifestyle medicine (LM) is one of the fastest growing medical specialties and has emerged as a high-value solution for root cause treatment of chronic disease. This review detailed a large integrated health care delivery system's value transformation efforts in the nonoperative treatment of musculoskeletal (MSK) conditions by placing patient-centric, team-based, lifestyle-focused care at the foundation. With an economic and treatment imperative to reimagine care, recognizing more intervention is not always better, a collaborative approach was designed, which placed functional improvement of the patient at the center. This article described the process of implementing LM into an MSK model of care. The change management process impacted clinical, operational, and benefit plan design to facilitate an integrated care model. A new understanding of patients' co-occurring physical impairments, medical comorbidities, and behavioral health needs was necessary for clinicians to make the shift from a pathoanatomic, transactional model of care to a biopsychosocial, longitudinal model of care. The authors explored the novel intersection of the implementation of a biopsychosocial model of care using LM principles to achieve greater value for the MSK patient population.

Comparison of Short-Term Effects of Different Spinal Manipulations in Patients with Chronic Non-Specific Neck Pain: A Randomized Controlled Trial

Spinal manipulations for chronic non-specific neck pain (CNNP) include cervical, cervicothoracic junction, and thoracic spine (CCT) manipulations as well as upper cervical spine (UCS) manipulations. This study aimed to compare the short-term effects of UCS manipulation versus a combination of CCT spine manipulations on pain intensity, disability, and cervical range of motion (CROM) in CNNP patients. In a private physiotherapy clinic, 186 participants with CNNP were randomly assigned to either the UCS (n = 93) or CCT (n = 93) manipulation groups. Neck pain, disability, and CROM were measured before and one week after the intervention. No significant differences were found between the groups regarding pain intensity and CROM. However, there was a statistically significant difference in neck disability, with the CCT group showing a slightly greater decrease (CCT: 16.9 ± 3.8 vs. UCS: 19.5 ± 6.8; p = 0.01). The findings suggest that a combination of manipulations in the CCT spine results in a slightly more pronounced decrease in self-perceived disability compared to UCS manipulation in patients with CNNP after one week. However, no statistically significant differences were observed between the groups in terms of pain intensity or CROM.

Active behavioural physiotherapy intervention for acute non-specific neck pain: a cluster randomised double-blind pilot and feasibility clinical trial

PURPOSE

To evaluate the feasibility of an active behavioural physiotherapy intervention (ABPI) and procedures to prevent the transition to chronicity in patients with acute non-specific neck pain (ANSNP).

MATERIALS AND METHODS

A cluster-randomised double-blind (assessors and participants), parallel 2-arm (ABPI versus standard physiotherapy intervention [SPI]) pilot and feasibility clinical trial was conducted owing to a pre-specified published protocol. Six public hospitals were recruited and cluster-randomised (computer-generated randomisation with block sampling). Sixty participants (30 in each arm, 10 per hospital) were assessed at baseline and 3 months following baseline for neck disability index, numerical pain rating scale, cervical range-of-motion, fear-avoidance beliefs questionnaire and EuroQol 5-dimension 5-level.

RESULTS

All procedures worked well. The participants' median age was 36.5 (range 21-59, interquartile range: 20.75) years. Participants in the ABPI demonstrated better improvement in all outcomes compared to SPI. Furthermore, the number of fully recovered participants following ABPI (27/30, 90.00%) was higher than SPI (16/30, 53.33%) with fewer treatment sessions and lower costs of management.

CONCLUSIONS

The findings suggest that the ABPI is feasible and valuable (e.g. a high number of fully recovered participants, fewer treatment sessions and reduced management costs compared to the SPI) in conducting a future definitive trial to evaluate the effectiveness of the ANSNP management.

Association between clinical biomechanical metrics of cervical spine function and pain or disability in people with neuromusculoskeletal neck pain: Protocol for a systematic review and planned meta-analysis

INTRODUCTION/BACKGROUND

Neck pain is a burdensome condition associated with pain, disability, and economic cost. Neck pain has been associated with observable changes in neuromuscular function and biomechanics. Prior research shows impairments in kinematic control, including reduced mobility, velocity, and smoothness of cervical motion. However, the strength of association between these impairments and patient-reported pain and disability is unclear rendering development of novel and relevant rehabilitation strategies difficult. The aim of this systematic review is to synthesize existing evidence on the strength of association between clinical biomechanical metrics of neck function (ROM, strength, acceleration, accuracy, smoothness, etc.) and patient-reported neck pain and disability.

METHODS/ANALYSIS

This protocol follows Cochrane guidelines and adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). MEDLINE, EMBASE, CINAHL, SPORTDiscus, Web of Science and Scopus will be searched, along with the gray literature, up to 20 November 2023, using terms and keywords derived from initial scoping searches. Observational studies, including cohorts and cross-sectional studies, that explore associations between clinical biomechanics of the neck and patient-reported outcomes of neck pain or disability will be included. Two reviewers will independently perform study selection, data extraction, and risk of bias assessment (National Institute of Health tool). Data will be synthesized using either a random effects meta-analytic approach or qualitatively using a modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, dependent on the homogeneity of data available.

DISCUSSION AND RELEVANCE

This review addresses a gap in the literature by systematically synthesizing findings on the relationship between neck function impairments and patient-reported outcomes. It will identify priorities for neck pain rehabilitation and gaps in current knowledge.

DISSEMINATION

The results of this review will be disseminated through a peer-reviewed publication, conference presentation, and lay language summaries posted on an open-access website.

The effects of neck exercise in comparison to passive or no intervention on quantitative sensory testing measurements in adults with chronic neck pain: A systematic review

BACKGROUND

Previous systematic reviews have identified the benefits of exercise for chronic neck pain on subjective reports of pain, but not with objective measures such as quantitative sensory testing (QST). A systematic review was conducted to identify the effects of neck specific exercise on QST measures in adults with chronic neck pain to synthesise existing literature and provide clinical recommendations.

METHODS

The study protocol was registered prospectively with PROSPERO (PROSPERO CRD42021297383). For both randomised and non-randomised trials, the following databases and trial registries were searched: AMED, CINAHL, Embase, Google Scholar, Medline, PEDro, PubMed, Scopus, SPORTDiscus, Science Citation Index and Social Science Citation Index from Web of Science Core Collection, clinicaltrials.gov, GreyOpen, and ISRCTN registry. These searches were conducted from inception to February 2022 and were updated until September 2023. Reference lists of eligible studies were screened. Study selection was performed independently by two reviewers, with data extraction and quality appraisal completed by one reviewer and independently ratified by a second reviewer. Due to high heterogeneity, narrative synthesis was performed with results grouped by exercise type.

FINDINGS

Three trials were included. Risk of bias was rated as moderate and the certainty of evidence as low or moderate for all studies. All exercise groups demonstrated statistically significant improvement at an intermediate-term follow-up, with progressive resistance training combined with graded physical training demonstrating the highest certainty of evidence. Fixed resistance training demonstrated statistically significant improvement in QST measures at a short-term assessment.

INTERPRETATION

Fixed resistance training is effective for short-term changes in pain sensitivity based on low-quality evidence, whilst moderate-quality evidence supports progressive resistance training combined with graded physical training for intermediate-term changes in pain sensitivity.

Education can reassure people with rotator cuff-related shoulder pain: a 3-arm, randomised, online experiment

ABSTRACT

We aimed to investigate the immediate effect of best practice education (with and without pain science messages) and structure-focused education on reassurance among people with rotator cuff-related shoulder pain. We conducted a 3-arm, parallel-group, randomised experiment. People with rotator cuff-related shoulder pain were randomised (1:1:1) to (1) best practice education (highlights that most shoulder pain is not serious or a good indicator of tissue damage and recommends simple self-management strategies); (2) best practice education plus pain science messages (which attempt to improve understanding of pain); and (3) structure-focused education (highlighting that structural changes are responsible for pain and should be targeted with treatment). Coprimary outcomes were self-reported reassurance that no serious condition is causing their pain and continuing with daily activities is safe. Secondary outcomes measured management intentions, credibility and relevance of the education, and similarity to previous education. Two thousand two hundred thirty-seven participants were randomised and provided primary outcome data. Best practice education increased reassurance that no serious condition is causing their pain (estimated mean effect 0.5 on a 0-10 scale, 95% confidence interval [CI] 0.2-0.7) and continuing with daily activities is safe (0.6, 95% CI 0.3-0.8) compared with structure-focused education . Adding pain science messages to best practice education slightly increased both measures of reassurance (0.2, 95% CI 0.0-0.4). Clinicians treating patients with rotator cuff-related shoulder pain should highlight that most shoulder pain is not serious or a good indicator of tissue damage and recommend simple self-management strategies. The benefit of adding pain science messages is small.

Assessment of the methodological, recommendation and reporting quality of global guidelines for neck pain and synthesis of evidence and recommendations: a systematic review protocol

INTRODUCTION

Neck pain is a global health problem that can cause severe disability and a huge medical burden. Clinical practice guideline (CPG) is an important basis for clinical diagnosis and treatment. A high-quality CPG plays a significant role in clinical practice. However, the quality of the CPGs for neck pain lacks comprehensive assessment. This protocol aims to evaluate the methodological, recommendation, reporting quality of global CPGs for neck pain and identify key recommendations and gaps that limit evidence-based practice.

METHOD

CPGs from January 2013 to November 2023 will be identified through a systematic search on 13 scientific databases (PubMed, Cochrane Library, Embase, etc) and 7 online guideline repositories. Six reviewers will independently evaluate the quality of CPGs for neck pain by using the Appraisal of Guidelines for Research and Evaluation, the Appraisal of Guidelines Research and Evaluation-Recommendations Excellence and the Reporting Items for Practice Guidelines in Healthcare tools. Intraclass correlation coefficient will be used to test the consistency of the assessment. We will identify the distribution of evidence and recommendations in each evidence-based CPGs for neck pain and regrade the level of evidence and strength of recommendations by adopting the commonly used Grading of Recommendations, Assessment, Development and Evaluations system. The key recommendations based on high-quality evidence will be summarised. In addition, we will categorise CPGs by different characteristics and conduct a subgroup analysis of the results of assessment.

ETHICS AND DISSEMINATION

No subjects will be involved in this systematic review, so there is no need for ethical approval. The finding of this review will be summarised as a paper for publication in a peer-reviewed journal.

Usability of a visual feedback system to assess and improve movement disorders related to neck pain: Perceptions of physical therapists and patients

A prototype visual feedback system has been developed to assess and improve movement disorders related to neck pain. The aim of this study was to assess the usability of the prototype in a rehabilitation setting. Twelve physical therapists integrated the device into their regular therapy programs for 24 neck pain patients with movement disorders. Each patient performed three individual therapy sessions with the device under physical therapist supervision. Usability was assessed by the physical therapists and patients using therapy diaries, the System Usability Scale, and focus group or personal interviews. Based on an overall usability rating of marginally acceptable, the visual feedback system was generally found to be a device with the potential to assess and train neck pain patients but needs improvement. To become a useful adjunct to regular physical therapy, improvements in the hardware and software, and further system developments are required.

An overview of systematic reviews examining the quantitative sensory testing-derived hypoalgesic effects of manual therapy for musculoskeletal pain

BACKGROUND

Changes in quantitative sensory testing (QST) after manual therapy can provide insight into pain relief mechanisms. Prior systematic reviews have evaluated manual-therapy-induced QST change. This overview of systematic reviews aims to consolidate this body of literature and critically review evidence on the hypoalgesic effects of manual therapy in clinical populations.

METHODS

A comprehensive search was conducted on PubMed, CINAHL, PsycInfo, and Embase. Peer-reviewed systematic reviews with or without meta-analysis were eligible if the reviews examined the effect of manual therapy compared to non-manual therapy interventions on QST outcomes in clinical populations. Methodological quality was assessed with the AMSTAR 2 tool. Meta-analysis results and qualitative (non-meta-analysis) interpretations were summarized by type of manual therapy. Overlap of studies was examined with the corrected covered area (CCA) index.

RESULTS

Thirty systematic reviews, including 11 meta-analyses, met inclusion. There was a slight overlap in studies (CCA of 1.72% for all reviews and 1.69% for meta-analyses). Methodological quality was predominantly low to critically low. Eight (27%) reviews examined studies with a range of manual therapy types, 13 (43%) reviews focused on joint-biased manual therapy, 7 (23%) reviews focused on muscle-biased manual therapy, and 2 (7%) reviews focused on nerve-biased manual therapy. Twenty-nine (97%) reviews reported on pressure pain threshold (PPT). Meta-analytic results demonstrated conflicting evidence that manual therapy results in greater hypoalgesic effects compared to other interventions or controls.

CONCLUSION

Our overview of QST effects, which has relevance to mechanisms underlying hypoalgesia, shows conflicting evidence from mostly low to critically low systematic reviews.

Clinical validation of grouping conservative treatments in neck pain for use in a network meta-analysis: a Delphi consensus study

BACKGROUND

A network meta-analysis aims to help clinicians make clinical decisions on the most effective treatment for a certain condition. Neck pain is multifactorial, with various classification systems and treatment options. Classifying patients and grouping interventions in clinically relevant treatment nodes for a NMA is essential, but this process is poorly defined.

OBJECTIVE

Our aim is to obtain consensus among experts on neck pain classifications and the grouping of interventions into nodes for a future network meta-analysis.

DESIGN

A Delphi consensus study involving neck pain experts worldwide.

METHODS

We invited authors of neck pain clinical practice guidelines published from 2014 onwards. The Delphi baseline questionnaire was developed based on the findings of a scoping review, including four items on classifications and 19 nodes. Participants were asked to record their level of agreement on a seven-point Likert scale or using Yes/No/Not sure answer options for the various statements. We used descriptive analysis to summarise the responses on each statement with content analysis of the free-text comments.

RESULTS

In total, 18/80 experts (22.5%) agreed to participate in one or more Delphi rounds. We needed three rounds to reach consensus for two classification of neck pain: one based on aetiology and one on duration. In addition, we also reached consensus on the grouping of interventions, including a definition of each node, with the number of nodes reduced to 17.

CONCLUSION

With this consensus we clinically validated two neck pain classifications and grouped conservative treatments into 17 well-defined and clinically relevant nodes.

Red flags for potential serious pathologies in people with neck pain: a systematic review of clinical practice guidelines

Introduction

We conducted a systematic review of clinical practice guidelines to identify red flags for serious pathologies in neck pain mentioned in clinical practice guidelines, to evaluate agreement in red flag recommendations across guidelines, and to investigate the level of evidence including what study type the recommendations are based on.

Methods

We searched for guidelines focusing on specific and nonspecific neck pain in MEDLINE, EMBASE, and PEDro up to June 9, 2023. Additionally, we searched for guidelines through citation tracking strategies, by consulting experts in the field, and by checking guideline organization databases.

Results

We included 29 guidelines, 12 of which provided a total of 114 red flags for fracture (n = 17), cancer (n = 21), spinal infection (n = 14), myelopathy (n = 15), injury to the spinal cord (n = 1), artery dissection (n = 7), intracranial pathology (n = 3), inflammatory arthritis (n = 2), other systemic disease (n = 6), or unrelated to a specific condition (n = 19). Overall, there is very little agreement (median Fleiss' kappa of 0) between guidelines on the red flags to screen for serious pathologies.

Conclusion

Red flags were mainly supported by expert opinions. We also observed a general lack of consensus among guidelines regarding which red flags to endorse. Considering the current limitations of the evidence, specific recommendations on which red flags to use cannot be provided, except for using the Canadian C-Spine rule for screening posttraumatic fractures.

The reliability of pressure pain threshold in individuals with low back or neck pain: a systematic review

Background and Objective

Low-back and neck pain affect a great number of individuals worldwide. The pressure pain threshold has the potential to be a useful quantitative measure of mechanical pain in a clinical setting, if it proves to be reliable in this population. The objectives of this systematic review are to: (1) analyze the literature evaluating the reliability of pressure pain threshold (PPT) measurements in the assessment of neck and low-back pain, (2) summarize the evidence from these studies, and (3) characterize the limitations of PPT measurement.

Databases and Data Treatment

Relevant literature from PubMed and the Web of Science electronic databases were screened in a 3-step process according to inclusion/exclusion criteria. Relevant studies were assessed for risk of bias using the Quality Appraisal of Reliability Studies (QAREL) tool, and results of all studies were summarized and tabulated.

Results

Of 922 citations identified, 11 studies were deemed relevant for critical appraisal, and 8 studies were deemed to have low risk-of bias. Intra-rater reliability, reported in all studies (n = 637) and inter-rater reliability, reported in 2 studies (n = 200) were consistently reported to be good to excellent (ICC 0.75-0.99 and ICC 0.81-0.90, respectively). Studies were also found to have significant variation in PPT measurement procedures.

Conclusions

Though intra- and inter-rater reliability was found to be high in all studies, the variation in PPT measurement protocols could affect validity and absolute reliability. As such, it is recommended that standard guidelines be developed for clinical use.

Effects of fasciatherapy versus fascial manipulation on pain, range of motion and function in patients with chronic neck pain

BACKGROUND

Neck pain is among the common musculoskeletal problem that hinders a person's daily activities. Fascial tightness is a familiar cause of chronic neck pain that is often neglected and can further cause neck disability and a limited range of motion.

OBJECTIVE

The purpose was to compare the effects of fascia therapy and fascial manipulation on pain, range of motion and function in patients with chronic neck pain.

METHODS

A randomized clinical trial was conducted from February to August 2022 in the Riphah Rehabilitation Centre, Lahore, Pakistan. Fifty-two participants of both genders, aged 18-40 years with chronic neck pain of at least 3-6 months were included. Group A (n = 26) received fascia therapy along with a conventional physical therapy protocol of hot pack, strengthening and stretching, while group B (n = 26) received the fascial manipulation treatment with conventional physical therapy. All the participants were assessed at baseline and after 3 weeks (3 sessions per week). Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI) and Goniometer (range of motions) were the outcome measures. SPSS 25 was used for the data analysis and normality of the data through the Shaphiro-Wilk test (p > 0.05), and parametric tests were applied.

RESULTS

The mean age of group A was 24.82 ± 2.64 years, and group B was 24.17 ± 2.20 years. The independent t-test result showed no significant difference (p ≥ 0.05) in all parameters except in cervical extension and right-side bending (p < 0.05). At the same time, the pair-wise comparison showed significant results (p < 0.05) for all outcome measures in both groups.

CONCLUSION

DBM fascia therapy improved cervical extension and side bending (right) more than the fascial manipulation group.It is concluded that DBM fascia therapy shows more improvement as compared to other group.

Effectiveness of Exercise Interventions for Preventing Neck Pain: A Systematic Review With Meta-analysis of Randomized Controlled Trials

OBJECTIVE: To update the evidence on the effectiveness of exercise interventions to prevent episodes of neck pain. DESIGN: Systematic review with meta-analysis. LITERATURE SEARCH: MEDLINE, Embase, CENTRAL, CINAHL, SPORTDiscus, PEDro, and trial registries from inception to December 2, 2022. Forward and backward citation searches. STUDY SELECTION CRITERIA: Randomized controlled trials (RCTs) that enrolled adults without neck pain at baseline and compared exercise interventions to no intervention, placebo/sham, attention control, or minimal intervention. Military populations and astronauts were excluded. DATA SYNTHESIS: Random-effects meta-analysis. Risk of bias was assessed using the Cochrane RoB 2 tool. The certainty of evidence was judged according to the GRADE approach. RESULTS: Of 4703 records screened, 5 trials (1722 participants at baseline) were included and eligible for meta-analysis. Most (80%) participants were office workers. Risk of bias was rated as some concerns for 2 trials and high for 3 trials. There was moderate-certainty evidence that exercise interventions probably reduce the risk of a new episode of neck pain (OR, 0.49; 95% confidence interval: 0.31, 0.76) compared to no or minimal intervention in the short-term (≤12 months). The results were not robust to sensitivity analyses for missing outcome data. CONCLUSION: There was moderate-certainty evidence supporting exercise interventions for reducing the risk for an episode of neck pain in the next 12 months. The clinical significance of the effect is unclear. J Orthop Sports Phys Ther 2023;53(10):1-16. Epub: 8 September 2023. doi:10.2519/jospt.2023.12063.

Efficacy of Combining Traditional Chinese Manual Therapy (Tuina) and Specific Therapeutic Neck Exercise in Young Adults with Non-Specific Chronic Neck Pain: Study Protocol for a Randomized Controlled Trial

Purpose

Non-specific chronic neck pain (NSCNP) is an increasingly common musculoskeletal disease and an important issue in the global healthcare system. Some studies have shown that the combination of manual therapy and exercise is effective in treating NSCNP but still with several limitations. Traditional Chinese manual therapy (tuina) is a Chinese manual therapy that consists of soft tissue manipulation and spinal manipulation. This study aims to design a randomized controlled trial to assess the effect of a tuina combined with specific therapeutic neck exercise modified protocol for NSCNP patients.

Patients and Methods

This is a study protocol for a randomized, participant-, assessor- and analyst-blinded controlled trial. Eighty-eight eligible NSCNP patients will be randomly allocated into tuina combined with specific therapeutic neck exercise group (TSTE group) and tuina combined with sham therapeutic neck exercise group (TS group) in a ratio of 1:1. All participants will receive 8 treatment sessions applied in 4 weeks and then be followed up for another 12 weeks. Clinical data will be collected at baseline, during treatment phase (at the 2- and 4-week) and at the 8-, 12-, 16-week follow-ups. The primary outcome is the changes in neck pain intensity (visual analogue scale). The secondary outcomes include neck disability (Neck Disability Index), cervical range of motion (ROM), neck muscle endurance, cervical muscle cross-sectional area, cervical curvature and analgesic consumption. Adverse events will be collected and recorded throughout the study.

Conclusion

We will discuss whether our tuina combined with specific therapeutic neck exercise modified protocol is more effective at improving pericervical muscle endurance, ROM, cervical muscle cross-sectional area and cervical curvature than tuina alone, thereby decreases neck pain and disability in individuals with NSCNP more effectively.

The Use of Virtual Reality in the Rehabilitation of Chronic Nonspecific Neck Pain: A Systematic Review and Meta-Analysis

OBJECTIVES

There has been a major interest in using virtual reality (VR) as a pain-management tool. This systematic review evaluated the literature on the use of VR in the treatment of chronic nonspecific neck pain (CNNP).

METHODS

Electronic database searches were conducted in Cochrane, Medline, PubMed, Web of Science, Embase, and Scopus between inception and November 22, 2022. Search terms used were synonyms of "chronic neck pain" and "virtual reality." Inclusion criteria were as follows: chronic neck pain patients or pain lasting longer than 3 months; nonspecific neck pain; adult population; VR intervention; and functional and/or psychological outcomes. Study characteristics, quality, participant demographics, and results were independently extracted by 2 reviewers.

RESULTS

VR interventions demonstrated significant improvement in patients experiencing CNNP. Scores in the visual analogue scale, the Neck Disability Index, and range of motion were significantly improved compared with baseline but not better than gold standard kinematic treatments.

DISCUSSION

Our results suggest that VR is a promising tool for chronic pain management; however, there is a lack of VR intervention design consistency, objective outcome measures, follow-up reporting, and large sample sizes. Future research should focus on designing VR interventions to serve specific, individualized movement goals as well as combining quantifiable outcomes with existing self-report measures.

Benefits and Harms of Spinal Manipulative Therapy for Treating Recent and Persistent Nonspecific Neck Pain: A Systematic Review With Meta-analysis

OBJECTIVE: We aimed to estimate the benefits and harms of cervical spinal manipulative therapy (SMT) for treating neck pain. DESIGN: Intervention systematic review with meta-analysis of randomized controlled trials (RCTs). LITERATURE SEARCH: We searched the MEDLINE, Cochrane CENTRAL, Embase, CINAHL, PEDro, Chiropractic Literature Index bibliographic databases, and grey literature sources, up to June 6, 2022. STUDY SELECTION CRITERIA: RCTs evaluating SMT compared to guideline-recommended and nonrecommended interventions, sham SMT, and no intervention for adults with neck pain were eligible for our systematic review. Prespecified outcomes included pain, range of motion, disability, health-related quality of life. DATA SYNTHESIS: Random-effects meta-analysis for clinically homogenous RCTs at short-term and long-term outcomes. Risk of bias was assessed using the Cochrane Risk of Bias 2.0 Tool. We used the Grading of Recommendations, Assessment, Development, and Evaluations approach to judge the certainty of evidence. RESULTS: We included 28 RCTs. There was very low to low certainty evidence that SMT was more effective than recommended interventions for improving pain at short term (standardized mean difference [SMD], 0.66; 95% confidence interval [CI]: 0.35, 0.97) and long term (SMD, 0.73; 95% CI: 0.31, 1.16), and for reducing disability at short-term (SMD, 0.95; 95% CI: 0.48, 1.42) and long term (SMD, 0.65; 95% CI: 0.23, 1.06). Transient side effects only were found (eg, muscle soreness). CONCLUSION: There was very low certainty evidence supporting cervical SMT as an intervention to reduce pain and improve disability in people with neck pain.

Treatment classifications and interventions for neck pain: a scoping review

OBJECTIVES

Our aim is to provide an overview of how neck pain is classified in the literature, define and group conservative interventions into 'nodes', and develop draft networks of interventions in preparation for a network meta-analysis (NMA).

STUDY DESIGN AND SETTINGS

We performed a scoping review. For feasibility reasons, we searched for randomized clinical trials (RCTs) via neck pain clinical practice guidelines (CPGs) published from 2014. We used standardized data extraction forms to extract data about classification of neck pain and interventions evaluated in the included RCTs. We calculated frequencies of neck pain classifications and grouped interventions into nodes based on the definitions used in Cochrane reviews. Draft network graphs comparing interventions were constructed using the online Shiny R application CINEMA.

RESULTS

We included 242 RCTs from seven CPGs, evaluating 28,581 patients. We found three different classification systems of which The Neck Pain Task Force classification was used most often. We defined and grouped all interventions into 19 discrete potential nodes.

CONCLUSION

We found a wide variation in neck pain classifications and conservative interventions. Grouping the interventions was challenging and needs further evaluation before conducting a final NMA.

Incomplete reporting of manual therapy interventions and a lack of clinician and setting diversity in clinical trials for neck pain limits replication and real-world translation. A scoping review

INTRODUCTION

Neck pain is a leading cause of disability, and manual therapy (MT) is a common intervention used across disciplines and settings to treat it. While there is consistent support for MT in managing neck pain, questions remain about the feasibility of incorporating MT from research into clinical practice. The purpose of this scoping review was to assess the adequacy of MT intervention descriptions and the variability in clinician and setting for MT delivery in trials for neck pain.

METHODS

Medline (via PubMed), CINAHL, PEDRo, and the Cochrane Central Registry for Controlled Trials were searched for clinical trials published from January 2010 to November 2021. A 11-item tool modified from the Consensus on Exercise Reporting Template was used to assess appropriateness of intervention reporting. Clinicians, subclassifications of neck pain, and clinical settings were also extracted.

RESULTS

113 trials were included. A low percentage of studies provided the recommended level of detail in the description of how MT was delivered (4.4%), while 39.0% included no description at all. Just over half of trials included clinician's qualifications (58.4%), dose of MT (59.3%), and occurrence of adverse events (55.8%). The proportion of trials with clinicians delivering MT were physical therapists (77.9%), chiropractors (10.6%), and osteopaths (2.7%).

DISCUSSION/CONCLUSION

These results reveal incomplete reporting of essential treatment parameters, and a lack of clinician diversity. To foster reproducibility, researchers should report detailed descriptions of MT interventions. Future research should incorporate a variety of MT practitioners to improve generalizability.

A Cross-Sectional Study on Mediating Effect of Chronic Pain on the Relationship between Cervical Proprioception and Functional Balance in Elderly Individuals with Chronic Neck Pain: Mediation Analysis Study

(1) Background: Cervical proprioception maintains head orientation in space and contributes to maintaining bodily balance. Evaluating cervical proprioception in elderly individuals with chronic neck pain (CNP) and understanding how pain intensity mediates the relationship between proprioception and functional balance helps formulate treatment strategies for this population. The objectives of this study are to (a) compare the cervical proprioception and functional balance between CNP and asymptomatic, (b) investigate the relationship between cervical proprioception and functional balance ability in CNP individuals and (c) mediation effect of chronic pain on the relationship between cervical proprioception and functional balance tests (2) Methods: This cross-sectional comparative study recruited 60 elderly individuals with a diagnosis of CNP (mean age: 66.40 years) and 60 asymptomatic (mean age: 66.42 years). The cervical proprioception is measured using the target head repositing technique. The subjects were asked to close their eyes and reposition their head actively to the target position from the neutral position, and the reposition accuracy is estimated as joint position errors (JPE) in degrees. The cervical proprioception was measured in the directions of flexion, extension, and left and right rotation. The functional balance was assessed using the berg balance test (BBS) score and timed-up-and-go (TUG) test in seconds. (3) Results: The elderly individuals with CNP had increased cervical JPE compared to the asymptomatic group (p < 0.001) in all the directions tested, indicating that cervical proprioception is impaired in CNP patients. Moreover, the CNP individual functional balance is significantly impaired (p < 0.001) compared to asymptomatic. The BBS test scores were lower, and the TUG scores were higher in the CNP group. In CNP individuals, the cervical JPE showed a significant correlation with the BBS test scores (r = -0.672 to -0.732, p < 0.001) and TUG scores (r = 0.328 to -0.414, p < 0.001). (4) Conclusions: Cervical proprioception and functional balance are impaired in elderly individuals with CNP. Physical therapists and rehabilitation professionals may consider these factors during the evaluation and development of treatment strategies in elderly adults with CNP.

A guide to identify cervical autonomic dysfunctions (and associated conditions) in patients with musculoskeletal disorders in physical therapy practice

BACKGROUND

Differential diagnosis is a hot topic in physical therapy, especially for those working in a direct access setting dealing with neck pain and its associated disorders. All international guidelines agree in recommending to first rule out non-musculoskeletal pathologies as the cause of signs and symptoms in the patient. Although the autonomic nervous system (ANS) has a crucial role and is also involved in pain conditions, coverage of it in neuroscience textbooks and educational programmes is limited and most healthcare professionals are unfamiliar with it. Although autonomic conditions are benign in nature, they are clinically of great importance as they may be a 'red flag' warning of an injury along the sympathetic pathway. Therefore, sound knowledge of the ANS system is essential for clinicians.

OBJECTIVE

To develop physical therapists' knowledge of and confidence in understanding cervical ANS function and dysfunction, thus enhancing clinical reasoning skills and the pattern recognition process, and performing and interpreting objective examinations.

METHODS

This master class provides an introductory guide and essential knowledge to facilitate clinicians to understand cervical autonomic dysfunctions and their clinical evaluation. The optimal referral method is also handled.

CONCLUSIONS

Gaining knowledge and understanding of the ANS, its function, its dysfunction, and the related clinical manifestations is likely to lead to a decision-making process driven by 'science and conscience'. This will empower physical therapists to be aware of subtle clues that may be offered by patients during the interview and history intake leading to the appropriate physical examination and triage.

Bee Venom Acupuncture for Neck Pain: A Review of the Korean Literature

Bee venom is a natural toxin that is effective in treating various types of pain. The purpose of this paper was to review all the features of clinical studies conducted on bee venom acupuncture (BVA) for the treatment of neck pain in Korean publications. Six Korean databases and 16 Korean journals were searched in August 2022 for clinical studies on BVA for neck pain. We identified 24 trials that met our inclusion criteria, of which 316 patients with neck pain were treated with BVA. The most common diagnosis in the patients with neck pain was herniated intervertebral discs (HIVDs) of the cervical spine (C-spine) (29.2%), and the concentration and dosage per session were 0.05-0.5 mg/mL and 0.1-1.5 mL, respectively. The visual analog scale was most often measured for neck pain severity (62.5%), and all clinical research reported improvements in 16 outcome measures. This study shows that BVA could be recommended for the treatment of neck pain, especially HIVD of the C-spine; however, the adverse effects of BVA must be examined in future studies.

The effects of osteopathic manipulative treatment on pain and disability in patients with chronic neck pain: A single-blinded randomized controlled trial

BACKGROUND

Neck pain (NP) affects up to 70% of individuals at some point in their lives. Systematic reviews indicate that manual treatments can be moderately effective in the management of chronic, nonspecific NP. However, there is a paucity of studies specifically evaluating the efficacy of osteopathic manipulative treatment (OMT).

OBJECTIVE

To evaluate the efficacy of OMT in reducing pain and disability in patients with chronic NP.

DESIGN

Single-blinded, cross-over, randomized-controlled trial.

SETTING

University-based, osteopathic manipulative medicine outpatient clinic.

PARTICIPANTS

Ninety-seven participants, 21 to 65 years of age, with chronic, nonspecific NP.

INTERVENTIONS

Participants were randomized to two trial arms: immediate OMT intervention or waiting period first. The intervention consisted of three to four OMT sessions over 4 to 6 weeks, after which the participants switched groups.

MAIN OUTCOME MEASURES

Primary outcome measures were pain intensity (average and current) on the numerical rating scale and Neck Disability Index. Secondary outcomes included Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) health domains and Fear Avoidance Beliefs Questionnaire. Outcomes obtained prior to the cross-over allocation were evaluated using general linear models and after adjusting for baseline values.

RESULTS

A total of 38 and 37 participants were available for the analysis in the OMT and waiting period groups, respectively. The results showed significantly better primary outcomes in the immediate OMT group for reductions in average pain (-1.02, 95% confidence interval [CI] -1.72, -0.32; p = .005), current pain (-1.02, 95% CI -1.75, -0.30; p = .006), disability (-5.30%, 95% CI -9.2%, -1.3%; p = .010) and improved secondary outcomes (PROMIS) related to sleep (-3.25, 95% CI -6.95, -1.54; p = .003), fatigue (-3.26, 95% CI -6.04, -0.48; p = .022), and depression (-2.59, 95% CI -4.73, -0.45; p = .018). The effect sizes were in the clinically meaningful range between 0.5 and 1 standard deviation. No study-related serious adverse events were reported.

CONCLUSIONS

OMT is relatively safe and effective in reducing pain and disability along with improving sleep, fatigue, and depression in patients with chronic NP immediately following treatment delivered over approximately 4 to 6 weeks.

Neck pain clinical practice guidelines: a systematic review of the quality and quantity of complementary and alternative medicine recommendations

BACKGROUND

Individuals with neck pain frequently turn to complementary and alternative medicine (CAM) to seek relief. However, conventional healthcare providers often lack adequate CAM therapy knowledge to deliver informed recommendations to patients. The purpose of this study was to identify mention of CAM in neck pain clinical practice guidelines (CPG) and assess the quality of CAM recommendations using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument.

METHODS

MEDLINE, EMBASE and CINAHL were systematically searched from 2009 to 2020 in addition to the Guidelines International Network and National Center for Complementary and Integrative Health websites. Eligible CPGs providing CAM recommendations were assessed twice with the AGREE II instrument, once to assess the overall CPG and then once to assess the CAM sections specifically.

RESULTS

From 643 unique search results, 15 CPGs on the treatment and/or management of neck pain were identified, and 8 made recommendations on CAM therapy. Regarding scaled domain percentages, the overall CPG scored higher than the CAM section for 5 of 6 domains (overall, CAM): (1) scope and purpose (93.4%, 93.1%), (2) stakeholder involvement (81.6%, 81.9%), (3) rigour of development (70.8%, 66.3%), (4) clarity of presentation (64.9%, 60.8%), (5) applicability (39.3%, 33.6%), and (6) editorial independence (47.9%, 45.3%).

CONCLUSIONS

Most neck pain CPGs made CAM recommendations. The quality of CAM recommendations is lower than overall recommendations across all domains with the exception of stakeholder involvement. This disparity highlights the need for CAM recommendations quality improvement. Although many patients with neck pain seek CAM therapies, few CPGs are available for healthcare providers and patients.

Some conservative interventions are more effective than others for people with chronic non-specific neck pain: a systematic review and network meta-analysis

QUESTION

Which is the most effective conservative intervention for patients with non-specific chronic neck pain (CNSNP)?

DESIGN

A systematic review and network meta-analysis of randomised clinical trials.

PARTICIPANTS

Adults with CNSNP of at least 3 months duration.

INTERVENTIONS

All available pharmacological and non-pharmacological interventions.

OUTCOME MEASURES

The primary outcomes were pain intensity and disability. The secondary outcome was adverse events.

RESULTS

Overall, 119 RCTs (12,496 patients; 32 interventions) were included. Risk of bias was low in 50.4% of trials, unclear in 22.7% and high in 26.9%. Compared with inert treatment, a combination of active and/or passive multimodal non-pharmacological inventions (eg, exercise and manual therapy) were effective for pain on a 0-to-10 scale at 1 month (MD range 0.84 to 3.74) and at 3 to 6 months (MD range 1.06 to 1.49), and effective on disability on a 0-to-100 scale at 1 month (MD range 10.26 to 14.09) and 3 to 6 months (MD range 5.60 to 16.46). These effects ranged from possible to definite clinical relevance. Compared with inert treatment, anti-inflammatory drugs alone or in combination with another non-pharmacological treatment did not reduce pain at 1 month or 3 to 6 months. At 12 months, no superiority was found over inert treatment on both outcomes. Most mild adverse events were experienced following acupuncture/dry needling intervention. On average, the evidence varied from low to very low certainty.

CONCLUSIONS

While multimodal non-pharmacological interventions may reduce pain and disability for up to 3 to 6 months of follow-up when compared with inert treatment, the evidence was very uncertain about their effects. Better quality and larger trials are needed to improve the certainty of evidence.

Spinal pain patients seeking care in primary care and referred to physiotherapy: A cross-sectional study on patients characteristics, referral information and physiotherapy care offered by general practitioners and physiotherapists in France

Objectives

To describe spinal pain patients referred by their treating general practitioners to physiotherapy care, examine to which extent physiotherapy interventions proposed by general practitioners and physiotherapists were compliant to evidence based recommendations, and evaluate concordance between providers in terms of diagnosis and contraindications to physiotherapy interventions.

Methods

This study included spinal pain patients recruited from a random sample of sixty French physiotherapists. Physiotherapists were asked to supply patients’ physiotherapy records and characteristics from the general practitioner’s physiotherapy referral for the five new consecutive patients referred to physiotherapy. General practitioner’s physiotherapy referral and physiotherapists’ clinical findings characteristics were analyzed and compared to evidence-based recommendations using Chi-squared tests. Cohen’s kappas were calculated for diagnosis and contraindications to physiotherapy interventions.

Results

Three hundred patients with spinal pain were included from sixty physiotherapists across France. The mean age of the patients was 48.0 ± 7.2 years and 53% were female. The most common spinal pain was low back pain (n = 147). Diagnoses or reason of referral formulated by general practitioners were present for 27% of all patients (n = 82). Compared to general practitioners, physiotherapists recommended significantly more frequently recommended interventions such as education, spinal exercises or manual therapy. General practitioners prescribed significantly more frequently passive physiotherapy approaches such as massage therapy and electrotherapy. The overall proportion of agreement beyond chance for identification of a diagnosis or reason of referral was 41% with a weak concordance (κ = 0.19; 95%CI: 0.08–0.31). The overall proportion of compliant physiotherapists was significantly higher than for general practitioners (76.7% vs 47.0%; p<0.001).

Conclusions

We found that information required for the referral of spinal pain patients to physiotherapy is often incomplete. The majority of general practitioners did not conform to evidence-based recommendations in terms of prescribed specific physiotherapy care; in contrast to a majority of physiotherapists.

Quality assessment of Japanese clinical practice guidelines including recommendations for acupuncture

Background

The quality of clinical practice guidelines (CPGs) should be extensively evaluated. This study aimed to evaluate Japanese CPGs that include recommendations for acupuncture.

Methods

In a literature search, CPGs including recommendations for acupuncture published in Japan until October 2021 were sought. We assessed (1) whether the CPGs were developed in accordance with the Grading Recommendations Assessment, Development and Evaluation (GRADE) system, (2) the quality of the CPGs using the Appraisal of Guidelines for Research and Evaluation (AGREE) II, and (3) whether the strength of the recommendations for acupuncture was consistent with each CPG's predefined procedure.

Results

Seventeen CPGs including 23 recommendations in total were identified and assessed. (1) Three CPGs were in accordance with the GRADE system. (2) The mean score of overall assessment using AGREE II was 4.5 on a 7-point Likert scale. The mean domain scores were 77% for domain 1 (scope and purpose), 54% for domain 2 (stakeholder involvement), 48% for domain 3 (rigor of development), 78% for domain 4 (clarity of presentation), 20% for domain 5 (applicability), and 51% for domain 6 (editorial independence). (3) The strength of the recommendations for acupuncture in two CPGs was judged to be underestimated. Some of the CPGs contained elementary problems that were not considered in AGREE II.

Conclusion

The methodological quality of Japanese CPGs including recommendations for acupuncture was not necessarily high. Since technical issues exist in each field of therapy, the respective experts should be involved in developing and reviewing CPGs to disseminate accurate health information.

Effectiveness of interventions for middle-aged and ageing population with neck pain: a systematic review and network meta-analysis protocol

INTRODUCTION

Neck pain (NP) is a common musculoskeletal complaint and is increasing in prevalence. Current clinical practice guidelines and systematic reviews recommended conservative, pharmacological and invasive interventions for individuals with NP. However, optimal management specifically for those who are middle-aged or older adults (≥45 years) is not available; and important considering our ageing population.

METHODS AND ANALYSIS

A systematic review with network meta-analysis (NMA) will be conducted following the Cochrane guidelines. Eligibility criteria include randomised controlled/clinical trials evaluating any of acute (<3 months) or chronic (≥3 months) non-specific NP, whiplash associated disorders, cervical radiculopathy and cervicogenic headache. Any interventions and outcome measures detailed within The International Classification of Functioning, Disability and Health domains will be included. Two independent reviewers will search key databases (AMED, CENTRAL, CINAHL, Embase, MEDLINE, PEDro and PsycINFO), grey literature, key journals and reference lists in May 2022. Two reviewers will decide eligibility and assess risk of bias (ROB) of included studies. The kappa statistic will be used to evaluate agreement between the reviewers at each stage. Data will be extracted by one reviewer and checked for accuracy by a second reviewer. Descriptive data and ROB will be summarised and tabulated. Traditional pairwise meta-analysis using random-effect model will be performed for all direct comparisons, and NMA using a frequentist random-effect model then performed based on NP classification where possible. A network of traditional pairwise meta-analysis allows comparisons of multiple interventions from both direct and indirect evidence to provide a hierarchal establishment for enhancing decision making of clinical practitioners.

ETHICS AND DISSEMINATION

Ethic approval is not required as the study is a literature review. The findings will be shared with the national and international researchers, healthcare professionals and the general public through publishing in a peer-reviewed journal and presentations at conferences.

Patients' satisfaction with physiotherapy management of chronic mechanical neck pain in physiotherapy departments of public hospitals in Ibadan, Nigeria: A mixed-method study

INTRODUCTION

The study was aimed at determining patients' satisfaction level with physiotherapy in the management of chronic mechanical neck pain (CMNP) in physiotherapy departments of the 3 public hospitals in Ibadan, Nigeria.

METHODS

A mixed-method design that involved 51 and five both purposively selected participants for the cross-sectional survey (CSS) and qualitative study, respectively. For the CSS, data was collected using the MedRisk instrument and analyzed using the Chi-square test at p ≤ .05. For the qualitative study, patients' satisfaction was explored through a focus group discussion (FGD) and analyzed using thematic analysis.

RESULTS

For CSS, 49.0% and 7.8% of the participants reported excellent and fair satisfaction, respectively, with physiotherapy in the management of CMNP. There was no significant association of patients' satisfaction level with: age (p = .588); sex (p = .851); and marital status (p = .409). For the FGD, three themes (patients' experience with physiotherapists; patient satisfaction with physiotherapy services; patient satisfaction with other health care services) that emerged further explained that participants were satisfied with physiotherapy management of their CMNP. However, they were not satisfied with the attitude of the record officers, constancy of the same treating physiotherapists, and unavailability of resources.

CONCLUSION

Patients with CMNP are satisfied with the physiotherapy care they received.

Head kinematics in patients with neck pain compared to asymptomatic controls: a systematic review

BACKGROUND

Neck pain is one of the most common musculoskeletal disorders encountered by healthcare providers. A precise assessment of functional deficits, including sensorimotor control impairment, is regarded necessary for tailored exercise programmes. Sensorimotor control can be measured by kinematic characteristics, such as velocity, acceleration, smoothness, and temporal measures, or by assessing movement accuracy. This systematic review aims to identify movement tasks and distinct outcome variables used to measure kinematics and movement accuracy in patients with neck pain and present their results in comparison to asymptomatic controls.

METHODS

Electronic searches were conducted in MEDLINE, PEDro, Cochrane Library and CINAHL databases from inception to August 2020. Risk of bias of included studies was assessed. Movement tasks and specific outcome parameters used were collated. The level of evidence for potential group differences in each outcome variable between patients with neck pain and controls was evaluated.

RESULTS

Twenty-seven studies examining head kinematics and movement accuracy during head-aiming, functional and unconstrained movement tasks of the head were included. Average Risk of Bias of included studies was moderate. In total, 23 different outcome variables were assessed. A strong level of evidence for an increased movement time and for an increased number of errors during head aiming tasks was found. Moderate evidence was found in traumatic neck pain for a decreased mean velocity, peak acceleration, and reaction time, and for point deviation and time on target during head aiming tasks. Moderate evidence was found for decreased acceleration during unconstrained movements, too. Results on the remaining movement task and outcome variables showed only limited, very limited or even conflicting level of evidence for patients with neck pain to differ from controls.

CONCLUSIONS

Sensorimotor control in NP in the way of kinematic and movement accuracy characteristics of head motion was examined in head aiming, functional or unconstrained movement tasks. The results from this review indicate that for some characteristics that describe sensorimotor control, patients with NP differ from healthy controls.

Effectiveness of Specific Neck Exercise for Nonspecific Neck Pain; Usefulness of Strategies for Patient Selection and Tailored Exercise-A Systematic Review With Meta-Analysis

OBJECTIVE

Specific neck exercises (SNE) targeting deep cervical flexors and extensors are commonly used for the treatment of nonspecific neck pain (NSNP). However, whether SNE are more effective than alternative exercise interventions (AEI) remains unclear. Furthermore, it has been postulated that SNE may be most effective when they are tailored and targeted to patients with evidence of motor control dysfunction, yet this notion also remains unproven. The objectives of this study were to compare the effectiveness of SNE with that of AEI for reducing pain and disability in people with NSNP and to assess whether the effectiveness of SNE is increased when the exercises are tailored and provided to patients with evidence of motor control dysfunction.

METHODS

For this systematic review with meta-analysis, Medline, Web of Science, Scopus, and Physiotherapy Evidence Database were searched. Eligibility criteria included randomized controlled trials evaluating the effectiveness of SNE against that of AEI in people with NSNP. Meta-analysis included subgroup analyses to determine the effect of exercise tailoring and participant selection criteria on the effectiveness of SNE.

RESULTS

Twelve studies were included. Meta-analysis revealed greater effectiveness of SNE in the short to medium term for reducing pain (pooled standardized mean difference [SMD] = -0.41; 95% CI = -0.76 to -0.06; P = .02) and disability (pooled SMD = -0.41; 95% CI = -0.78 to -0.04; P = .03) but no differences in the long term for pain (pooled SMD = -1.30; 95% CI = -3.35 to 0.75; P = .21) and disability (pooled SMD = -1.81; 95% CI = -4.29 to 0.67; P = .15), although evidence was limited for the latter. The effectiveness of SNE was not superior in studies that included only participants with motor control dysfunction or when exercises were tailored to each participant. Overall, the studies were of low quality. Grading of Recommendations Assessment, Development and Evaluation revealed low certainty, serious risk of bias, and inconsistency of findings for short- to medium-term effects and very low certainty, serious risk of bias, and very serious inconsistency for long-term effects.

CONCLUSION

The preferential use of SNE may be recommended to achieve better short- to medium-term outcomes, although the low quality of evidence affects the certainty of these findings. Currently used strategies for selecting patients and tailoring SNE are not supported by the evidence and therefore cannot be recommended for clinical practice.

IMPACT

SNE are more effective than AEI for reducing pain and disability in patients with NSNP in the short to medium term, but overall evidence is of low quality, affecting the certainty of the findings. Tests of muscle dysfunction (mostly the craniocervical flexion test) currently used in studies to select patients and tailor SNE do not result in greater effectiveness of these exercises.

LAY SUMMARY

Evidence suggests SNE are more effective than other forms of exercise, although evidence is overall of low quality. Use of the craniocervical flexion test in isolation to select participants and/or tailor SNE cannot be recommended.

No Uniformity in the References of Clinical Practice Guidelines for Bariatric Surgery: a Review of 3 Similar Guidelines Published in 2020

In 2020, updated versions of the clinical practice guidelines of the European Association for Endoscopic Surgery, the Canadian Adult Obesity Clinical Practice Guidelines and the Dutch Federation for Medical Specialist clinical practice guidelines on bariatric surgery were published. We systematically reviewed and compared them on recommendations and references. Although the authors would have had access to the same literature, only 5 out of 655 unique references were used by all 3 guidelines and just 49 references by any combination of 2 guidelines. These findings attest to the subjectivity involved in clinical practice guidelines development and could be the cause for the observed differences in recommendations. International cooperation in guideline development might be a conceivable solution.

The effect of spinal manipulative therapy and home stretching exercises on heart rate variability in patients with persistent or recurrent neck pain: a randomized controlled trial

BACKGROUND

Persistent or recurrent neck pain is, together with other chronic conditions, suggested to be associated with disturbances of the Autonomic Nervous System. Acute effects on the Autonomic Nervous System, commonly measured using Heart Rate Variability, have been observed with manual therapy. This study aimed to investigate the effect on Heart Rate Variability in (1) a combination of home stretching exercises and spinal manipulative therapy versus (2) home stretching exercises alone over 2 weeks in participants with persistent or recurrent neck pain.

METHODS

A randomized controlled clinical trial was carried out in five multidisciplinary primary care clinics in Stockholm from January 2019 to April 2020. The study sample consisted of 131 participants with a history of persistent or recurrent neck. All participants performed home stretching exercises daily for 2 weeks and were scheduled for four treatments during this period, with the intervention group receiving spinal manipulative therapy in addition to the home exercises. Heart Rate Variability at rest was measured at baseline, after 1 week, and after 2 weeks, with RMSSD (Root mean square of successive RR interval differences) as the primary outcome. Both groups were blinded to the other group intervention. Thus, they were aware of the purpose of the trial but not the details of the "other" intervention. The researchers collecting data were blinded to treatment allocation, as was the statistician performing data analyses. The clinicians provided treatment for participants in both groups and could not be blinded. A linear mixed-effects model with continuous variables and person-specific random intercept was used to investigate the group-time interaction using an intention to treat analysis.

RESULTS

Sixty-six participants were randomized to the intervention group and sixty-five to the control group. For RMSSD, a B coefficient of 0.4 (p value: 0.9) was found, indicating a non-significant difference in the regression slope for each time point with the control group as reference. No statistically significant differences were found between groups for any of the Heart Rate Variability indices.

CONCLUSION

Adding four treatments of spinal manipulation therapy to a 2-week program of daily stretching exercises gave no significant change in Heart Rate Variability.

TRIAL REGISTRATION

The trial was registered 03/07/2018 at ClinicalTrials.gov, registration number: NCT03576846. ( https://pubmed.ncbi.nlm.nih.gov/31606042/ ).

Cervical disc degeneration: important considerations for the manual therapist

Cervical disc degeneration (CDD) is a progressive, age-related occurrence that is frequently associated with neck pain and radiculopathy. Consistent with the majority of published clinical practice guidelines (CPG) for neck pain, the 2017 American Physical Therapy Association Neck Pain CPG recommends cervical manipulation as an intervention to address acute, subacute, and chronic symptoms in the 'Neck Pain With Mobility Deficits' category as well for individuals with 'Chronic Neck Pain With Radiating Pain'. While CPGs are evidence-informed statements intended to help optimize care while considering the relative risks and benefits, these guidelines generally do not discuss the mechanical consequences of underlying cervical pathology nor do they recommend specific manipulation techniques, with selection left to the practitioner's discretion. From a biomechanical perspective, disc degeneration represents the loss of structural integrity/failure of the intervertebral disc. The sequelae of CDD include posterior neck pain, segmental hypermobility/instability, radicular symptoms, myelopathic disturbance, and potential vascular compromise. In this narrative review, we consider the mechanical, neurological, and vascular consequences of CDD, including information on the anatomy of the cervical disc and the mechanics of discogenic instability, the anatomic and mechanical basis of radiculitis, radiculopathy, changes to the intervertebral foramen, the importance of Modic changes, and the effect of spondylotic hypertrophy on the central spinal canal, spinal cord, and vertebral artery. The pathoanatomical and biomechanical consequences of CDD are discussed, along with suggestions which may enhance patient safety.

Physiotherapist-led rehabilitation for patients with chronic musculoskeletal pain: interventions and promising long-term outcomes

BACKGROUND

There is no consensus on best content, set-up, category of involved healthcare professionals or duration of rehabilitation-programs for patients with chronic musculoskeletal pain, and outcomes show varying results. Individual care regimes for sub-groups of patients have been proposed.

AIM

To describe the type of interventions used in a physiotherapist-led, rehabilitation-program for patients with chronic musculoskeletal pain, refractory to preceding treatments. A second aim was to report clinical outcomes at 1-year follow-up after the intervention period.

METHODS

All patients referred to physiotherapist within a specialist pain-unit due to being refractory to preceding treatments, and deemed fit to undergo physiotherapy-based, individualized rehabilitation during 2014-2018 were consecutively included and followed-up 1 year after ending the program. The inclusion was based on structured 'clinical reasoning' using the referral, examination and on patient-relevant outcome measures. The individual interventions, recorded according to a manual used when reading the patients' medical records, were described. Primary outcomes were clinical results of perceived pain, disability and overall health at start, discharge and 1 year after discharge.

RESULTS

In total, 274 patients (mean age 42 years, 71% women) were included, suffering from chronic, severe, musculoskeletal pain (VAS median 7/10, duration median 2.8 years) and moderate disability. The most frequent interventions were education, sensorimotor training, physical activity-advice and interventions for structures/functions (for example manual techniques, stretching) for a median of nine sessions during five months. Despite refractory to preceding treatments, 45% of the patients rated clinically important improvements on pain, 61% on disability and 50% on overall health at discharge and the figures were similar at 1-year follow-up.

CONCLUSIONS

A physiotherapist-led, one-to-one, rehabilitation-program of median nine sessions during five months, combining individualized education, sensorimotor training, physical activity-advice and interventions for structures/functions rendered clinically relevant improvements on pain, disability and overall health in half of the patients at 1-year follow-up. Since the cohort consisted of patients refractory to preceding treatments, we believe that these results warrant further studies to identify the subgroups of patients with chronic musculoskeletal pain that will improve from new, distinctive, resource-effective rehabilitation-programs involving individualized rehabilitation.

The effect of two weeks of spinal manipulative therapy and home stretching exercises on pain and disability in patients with persistent or recurrent neck pain; a randomized controlled trial

Background

Recurrent or persistent neck pain affects a vast number of people globally, leading to reduced quality of life and high societal costs. Clinically, it is a difficult condition to manage, and treatment effect sizes are often moderate at best. Activity and manual therapy are first-line treatment options in current guidelines. We aimed to investigate the combination of home stretching exercises and spinal manipulative therapy in a multicentre randomized controlled clinical trial, carried out in multidiscipline ary primary care clinics.

Methods

The treatment modalities utilized were spinal manipulative therapy and home stretching exercises compared to home stretching exercises alone. Both groups received 4 treatments for 2 weeks. The primary outcome was pain, where the subjective pain experience was investigated by assessing pain intensity (NRS − 11) and the quality of pain (McGill Pain Questionnaire). Neck disability and health status were secondary outcomes, measured using the Neck Disability Indexthe EQ-5D, respectively. One hundred thirty-one adult subjects were randomized to one of the two treatment groups. All subjects had experienced persistent or recurrent neck pain the previous 6 months and were blinded to the other group intervention. The clinicians provided treatment for subjects in both group and could not be blinded. The researchers collecting data were blinded to treatment allocation, as was the statistician performing data analyses. An intention-to-treat analysis was used.

Results

Sixty-six subjects were randomized to the intervention group, and sixty-five to the control group. For NRS − 11, a B-coefficient of − 0,01 was seen, indication a 0,01 improvement for the intervention group in relation to the control group at each time point with a p-value of 0,305. There were no statistically significant differences between groups for any of the outcome measures.

Conclusion

Efficacy of Yijinjing combined with Tuina for patients with non-specific chronic neck pain: study protocol for a randomized controlled trial

BACKGROUND

Non-specific chronic neck pain (NCNP) is a common musculoskeletal disorder which has caused a huge economic burden due to its expensive health costs and high re-occurrence rate. Yijinjing and Tuina are widely used for non-specific chronic neck pain in China. But there is little scientific evidence to evaluate their efficacy for NCNP. The aim of this research is to compare the efficacy of Yijinjng combined with Tuina versus Tuina for patients with NCNP.

METHODS/DESIGN

A randomized controlled trial in which 102 patients with non-specific chronic neck pain will be recruited and randomly allocated to either the Tuina group or the Yijinjng combined with Tuina group in a 1:1 ratio. The interventions for both groups will be carried out three times a week for 8 weeks. The patients in the two groups will receive follow-up 1 month after the intervention. The primary outcome will be the changes in the visual analog scale (VAS). Secondary outcomes will be measured by the Neck Disability Index (NDI), Self-Rating Anxiety Scale (SAS), and Tissue Hardness and Active Range of Motion (AROM). The data will be analyzed at the baseline, 4 weeks during the intervention, at the end of the intervention, and 1 month after the intervention. The significance level sets as 5%. The safety of interventions will be evaluated after each treatment session.

DISCUSSION

The purpose of this trial is to determine whether Yijinjing combined with Tuina is not inferior to Tuina for patients with NCNP. This study will provide clinicians and stakeholders much-needed knowledge for a complementary and alternative therapy for patients with non-specific chronic neck pain.

Risk of Treatment Escalation in Recipients vs Nonrecipients of Spinal Manipulation for Musculoskeletal Cervical Spine Disorders: An Analysis of Insurance Claims

OBJECTIVE

The purpose of this study was to evaluate the relationship between treatment escalation and spinal manipulation in a retrospective cohort of people diagnosed with musculoskeletal disorders of the cervical spine.

METHODS

We used retrospective analysis of insurance claims data (2012-2018) from a single Fortune 500 company. After isolating the first episode of care, we categorized 58 147 claims into 7951 unique patient episodes. Treatment escalation included claims where imaging, injection, emergency room, or surgery was present. Modified Poisson regression was used to determine the relative risk of treatment escalation comparing recipients vs nonrecipients of spinal manipulation, adjusted for age, sex, episode duration, and risk scores.

RESULTS

The sample was 55% women, with a mean age of 44 years (range, 18-103). Treatment escalation was present in 42% of episodes overall: 2448 (46%) associated with other care and 876 (26%) associated with spinal manipulation. The estimated risk of any treatment escalation was 2.38 times higher in those who received other care than in those who received spinal manipulation (95% confidence interval, 2.22-2.55, P = .001).

CONCLUSION

Among episodes of care associated with neck pain diagnoses, those associated with other care had twice the risk of any treatment escalation compared with those associated with spinal manipulation. In the United States, over 90% of spinal manipulation is provided by doctors of chiropractic; therefore, these findings are relevant and should be considered in addressing solutions for neck pain. Additional research investigating the factors influencing treatment escalation is necessary to moderate the use of high-cost and guideline-incongruent procedures in people with neck pain.

What Determines the Quality of Rehabilitation Clinical Practice Guidelines?: An Overview Study

OBJECTIVE

The aim of the study was to determine what factors determine the quality of rehabilitation clinical practice guidelines.

DESIGN

Six databases were searched for articles that had applied the Appraisal of Guidelines for Research & Evaluation II quality assessment tool to rehabilitation clinical practice guidelines. The 573 deduplicated abstracts were independently screened by two authors, resulting in 81 articles, the full texts of which were independently screened by two authors for Appraisal of Guidelines for Research & Evaluation II application to rehabilitation clinical practice guidelines, resulting in a final selection of 40 reviews appraising 504 clinical practice guidelines. Data were extracted from these by one author and checked by a second. Data on each clinical practice guideline included the six Appraisal of Guidelines for Research & Evaluation II domain scores, as well as the two Appraisal of Guidelines for Research & Evaluation II global evaluations.

RESULTS

All six Appraisal of Guidelines for Research & Evaluation II domain scores were statistically significant predictors of overall clinical practice guideline quality rating; D3 (rigor of development) was the strongest and D1 (scope and purpose) the weakest (overall model P < 0.001, R2 = 0.53). Five of the six domain scores were significant predictors of the clinical practice guideline use recommendation, with D3 the strongest predictor and D5 (applicability) the weakest (overall model P < 0.001, pseudo R2 = 0.53).

CONCLUSIONS

Quality of rehabilitation clinical practice guidelines may be improved by addressing key domains such as rigor of development.

Chuna Manual Therapy vs Usual Care for Patients With Nonspecific Chronic Neck Pain: A Randomized Clinical Trial

IMPORTANCE

The incidence rate of neck pain is increasing worldwide, and the disease is associated with a high social burden. Manual therapy has been widely applied in the treatment of neck pain, but a high-quality, pragmatic randomized clinical trial for this treatment has not been conducted to date.

OBJECTIVE

This study aimed to compare the effectiveness of Chuna manual therapy with that of usual care for patients with chronic neck pain.

DESIGN, SETTING, AND PARTICIPANTS

A multicenter, assessor-blinded, pragmatic, randomized clinical trial was conducted between October 18, 2017, and June 28, 2019. This intention-to-treat analysis included 108 patients with chronic neck pain persisting for at least 3 months; patients were recruited from 5 hospitals in Korea.

INTERVENTIONS

Ten sessions (2 sessions per week for 5 weeks) of Chuna manual therapy or usual care (electrotherapy and oral medication) were conducted.

MAIN OUTCOMES AND MEASURES

The main outcome was the difference in visual analog scale (VAS) score for chronic neck pain between baseline and 5 weeks after randomization.

RESULTS

This randomized clinical trial recruited 108 patients (mean [SD] age, 38.4 [9.3] years; 73 women [67.6%]). Fifty-four patients were allocated to the Chuna therapy group, and 54 received usual care. At 5 weeks after randomization, manual therapy showed statistically superior results compared with usual care in terms of pain (difference in chronic neck pain VAS, 16.8 mm; 95% CI, 10.1-23.5 mm), function (difference in Neck Disability Index, 8.6%; 95% CI, 4.2%-13.1%), and quality of life (difference in the European Quality of Life-5 Dimension 5 Levels (EQ-5D-5L) scores, -0.07 points; 95% CI, -0.11 to -0.02 points). Regarding the 1-year cumulative values measured using area under the curve analyses, superior outcomes were attained in the manual therapy group in terms of the numerical rating scale for chronic neck pain (1.3 points; 95% CI, 0.5-2.0 points), Neck Disability Index (6.7%; 95% CI, 2.5%-10.9%), Neck Pain Questionnaire (7.4%; 95% CI, 2.3%-12.6%), and EQ-5D-5L scores (-0.03 points; -0.07 to 0.00 points).

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, for patients with chronic neck pain, Chuna manual therapy was more effective than usual care in terms of pain and functional recovery at 5 weeks and 1 year after randomization. These results support the need to consider recommending manual therapies as primary care treatments for chronic neck pain.

The clinical management of neck pain of novice and experienced Australian osteopaths: A secondary analysis of a nationally representative sample

INTRODUCTION

Neck pain is one of the most common musculoskeletal disorders worldwide. Osteopaths are primary contact health professionals who predominantly manage musculoskeletal complaints. How Australian osteopaths manage neck pain is beginning to emerge in the literature and there may be differences based on clinical experience. This work presents a secondary data analysis of the Australian osteopathy practice-based research network and aims to examine the clinical management characteristics of experienced and novice osteopaths who often treat neck pain.

METHODOLOGY

Secondary analysis of a cross-sectional survey of osteopaths registered with the Osteopathy Research and Innovation Network (ORION), an Australian practice-based research network. Demographic, practice and treatment characteristics of osteopaths who 'often' treat neck pain. Data was split into two groups: novice practitioners (up to nine years in clinical practice), and experienced practitioners (10 years or more in clinical practice), and clinical management was compared.

RESULTS

Most (98%) of the 971 osteopaths reported that they treat neck pain often. Of those that treat neck pain often, 58% reported being male. The mean number of patient care hours per week was 28.1 ± 12.1 and the mean number of patient visits per week was 36.7 ± 18.7. There was a statistically significant difference between novice and experienced groups for discussing occupation (p < 0.01; d = 0.26) and stress (p = 0.045; d = 0.13) during their consultations, with a low to medium and low effect size, respectively.

CONCLUSION

This work demonstrates differences in the management strategies of experienced and novice Australian osteopaths that includes utilisation of a multidisciplinary approach to patient management. The results support the conclusion that there are differences in the clinical management strategies employed by experienced versus novice Australian osteopaths.

The development and evaluation of an online educational tool for the evidence-based management of neck pain by chiropractic teaching faculty

OBJECTIVE

To develop an online, interactive educational tool to deliver an evidence-based clinical practice guideline to faculty members at a Canadian chiropractic college. Second, to evaluate the learning, design, and engagement constructs of the tool in a sample of chiropractic faculty members.

METHODS

Using an integrated knowledge translation methodology and the Knowledge to Action Framework, we developed an evidence-based online learning tool. The context of the tool focused on a clinical practice guideline on the management of neck pain. We evaluated the learning, design, and engagement constructs in a sample of faculty members and residents using the Learning Object Evaluation Scale for Students. Participants were also asked to provide suggestions for improvement of the tool.

RESULTS

Sixteen participants completed the evaluation. Most (68.8%) participants were chiropractors, 75% were male and 56% were between the ages of 25 and 44 years. At least 75% of participants agreed that the learning, design, and engagement constructs of the learning tool were adequate. The open-ended suggestions unveiled 3 pedagogical themes, relating to multimedia, thinking skills, and learner control, within the tool that could benefit from further development. These themes informed recommendations to improve the tool.

CONCLUSION

Our online, interactive, module-based learning tool has sound pedagogical properties. Further research is needed to determine if its use is associated with a change in knowledge.

Effectiveness of standard cervical physiotherapy plus diaphragm manual therapy on pain in patients with chronic neck pain: A randomized controlled trial

BACKGROUND

Literature concerning the effect of diaphragm treatment to reduce neck pain symptoms is scarce. Aim of this trial was to investigate the effects of diaphragm manual therapy associated with standard physiotherapy treatment on pain in patients with Chronic Neck Pain (CNP).

METHODS

In a private practice clinic, subjects with CNP were randomly assigned to receive three 30-min treatment sessions of standard cervical physiotherapy and Diaphragm Manual Therapy (DMT) or Sham Diaphragm Technique (SDT). Participants and assessors were blinded to the assignment. Primary outcome was pain, secondary outcomes were cervical active range of motion, pain pressure threshold, disability and quality of life measured at baseline, before and after each session, at 3 and 6-months. Adverse events were monitored. A non-parametric multivariate approach (combined permutation test) was applied to assess the effect of the treatment on all the outcomes. An intention to treat analysis was performed.

RESULTS

Forty patients were randomly allocated to DMT and SDT groups. Combined permutation test showed a significant higher improvement in DMT group compared to SDT group (p-value = 0.0002). The between-group comparisons on single outcomes showed a statistically significant improvement only for pain pressure threshold on upper trapezius (adjusted p-value = 0.029). No adverse events related to the intervention were registered.

CONCLUSIONS

In patients with CNP, addition of diaphragm manual techniques to standard cervical treatment seems to give a better global outcome, but this improvement is of unclear clinical relevance; the primary outcome seems not to have a role. Further studies are needed to confirm and clarify these results.
