Manual therapy and exercise for neck pain: A systematic review

The effects of exercise on neuromuscular function in people with chronic neck pain: A systematic review and meta-analysis

BACKGROUND

Differences in cervical neuromuscular function are commonly observed between people with and without chronic neck pain. Exercise may improve cervical neuromuscular function of people with neck pain although the evidence for this has not been systematically reviewed.

OBJECTIVE

To systematically review the existing evidence on the effect of exercises targeting the neck muscles on neuromuscular function in people with chronic non-specific neck pain.

METHODS

This systematic review was conducted based on a registered protocol (CRD42021298831) with searches conducted on the following databases from inception to 21st October 2023: MEDLINE, CINAHL, Web of Science, Scopus, AMED, Google Scholar, Open Grey and Zetoc. Studies of interest were trials investigating neuromuscular adaptations to a program of exercise targeting the neck muscles (>2 weeks) in people with chronic non-specific neck pain. Two reviewers independently screened the studies and performed data extraction, risk of bias assessment, and rated the overall certainty of the evidence (GRADE).

RESULTS

Fourteen articles from 2110 citations were included. There is moderate certainty of evidence that the use of craniocervical flexion training (either in isolation or in combination with resistance training) can induce neural adaptations within the neck muscles. A meta-analysis showed a reduction in sternocleidomastoid muscle activity after neck exercise interventions compared to control interventions.

CONCLUSION

The articles included in this systematic review confirmed that exercise can result in neuromuscular adaptations within neck muscles, as measured by electromyography. Specificity of training was seen to be relevant for the type of neuromuscular adaptations induced.

Knowledge and utilization of manual therapy in the management of knee osteoarthritis by physical therapists in Saudi Arabia: a cross-sectional study

BACKGROUND

The knowledge and utilization of manual therapy in treating knee osteoarthritis (OA) may help explain the effective utilization of manual therapy for managing knee OA. Little is known about the knowledge and utilization of manual therapy in the management of knee OA by physical therapists (PTs) in Saudi Arabia. The present study aimed to evaluate the knowledge and utilization of manual therapy by PTs in Saudi Arabia via a survey method.

METHODS

A cross-sectional study design was used. PTs working in various hospitals in Saudi Arabia participated. A 29-item questionnaire was developed based on previous studies. One hundred ninety-seven participants returned the completed questionnaire (response rate, 78.8%). Descriptive statistics were utilized to summarize and present the study participants' characteristics and responses.

RESULTS

Approximately one-third (35.2%) of the participants did not receive any formal manual therapy training, whereas the others received formal manual therapy training in undergraduate (23.8%) or postgraduate (40.9%) studies. Only approximately one-third of the participants (29.9%) were qualified as certified manual therapy practitioners. Most participants (57%) reported using manual therapy according to the patient's condition. Most of the participants cited several treatment goals for manual therapy, including pain reduction (84.8%), improved range of motion (77.2%), increased mobility (58.2%), and improved function (55.4%).

CONCLUSIONS

PTs in Saudi Arabia showed a positive attitude toward using manual therapy for treating knee OA. However, they suggested combining exercise and manual therapy as the best treatment option for knee OA.

Manual physical therapy for neck disorders: an umbrella review

INTRODUCTION

Neck pain is a common musculoskeletal disorder, with a prevalence rate (age-standardized) of 27.0 per 1000 in 2019. Approximately 50-85% of individuals with acute neck pain do not experience complete resolution of symptoms, experiencing chronic pain. Manual therapy is a widely employed treatment approach for nonspecific neck pain (NSNP), cervical radiculopathy (CR) and cervicogenic headaches (CGH). This umbrella review synthesized systematic reviews examining manual physical therapy for individuals with cervical disorders.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed with Prospero registration (CRD42022327434). Four databases were searched from January 2016 to May 2023 for systematic reviews with or without meta-analysis examining manual therapy for individuals with neck pain of any stage. Interventions included any manual physical therapy of the cervical or thoracic spine as well as neuromobilization of the upper quarter. Primary outcomes included pain and disability. Two reviewers screened for eligibility and completed data extraction. Methodological quality was assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2) tool.

RESULTS

A total of 35 SRs were included: 15 NSNP, 7 cervical radiculopathy, 9 CGH and 4 samples with combined diagnoses. AMSTAR 2 ratings of the SRs support high confidence in results for 10 reviews, moderate confidence in 12 reviews and low to critically low confidence in 13 reviews. For NSNP, there was high confidence in the results showing manual therapy combined with exercise was superior to either treatment in isolation. In cervical radiculopathy, neural mobilization, distraction, soft tissue treatment and mobilization/manipulation to cervical and thoracic spine were supported with moderate confidence in results. For CGH, there was high confidence in the results supporting the use of cervical spine mobilization/manipulation, soft tissue mobilization, and manual therapy combined with exercise. Original authors of SRs reported varying quality of primary studies with lack of consistent high quality/low risk of bias designs.

CONCLUSION

Manual therapy plus exercise, cervical or thoracic mobilization and manipulation, neuromobilization, and other types of manual therapy were supported as effective interventions in the management of pain and disability for individuals with NSNP, CGH, or CR in the short-term.

Reduced Cervical Muscle Fat Infiltrate Is Associated with Self-Reported Recovery from Chronic Idiopathic Neck Pain Over Six Months: A Magnetic Resonance Imaging Longitudinal Cohort Study

Background: It is unclear why neck pain persists or resolves, making assessment and management decisions challenging. Muscle composition, particularly muscle fat infiltrate (MFI), is related to neck pain, but it is unknown whether MFI changes with recovery following targeted interventions. Methods: We compared muscle composition quantified from fat-water magnetic resonance images from the C3 to T1 vertebrae in individuals with and without chronic idiopathic neck pain at two times 6 months apart. Those with neck pain received six weeks of intervention (physiotherapy or chiropractic) after their baseline MRI; at 6 months, they were classified as recovered (≥3 on the 11-point Global Rating of Change scale) or not recovered. Results: At 6 months, both asymptomatic and recovered individuals had decreased MFI compared to baseline (asymptomatic estimated marginal mean difference -1.6% 95%; CI -1.9, -1.4; recovered -1.6; -1.8, -1.4; p < 0.001) whereas those classified as not recovered had increased MFI compared to baseline (0.4; 0.1, 0.7; p = 0.014), independent of age, sex and body mass index. Conclusions: It appears MFI decreases with recovery from neck pain but increases when neck pain persists. The relationship between cervical MFI and neck pain suggests MFI may inform diagnosis, theragnosis and prognosis in individuals with neck pain. Future development of a clinical test for MFI may assist in identifying patients who will benefit from targeted muscle intervention, improving outcomes.

Efficacy of Therapeutic Exercise in Reducing Pain in Instrumental Musicians: Systematic Review and Meta-Analysis

Playing-related pain poses a significant health concern for musicians, often impacting their ability to perform. Therapeutic exercise emerges as a viable approach to alleviate these symptoms, offering a low-cost intervention with minimal side effects. This review seeks to examine and assess the efficacy of therapeutic exercise in reducing pain intensity among instrumental musicians. Three major databases (PubMed, Web of Science, and Scopus) were systematically searched from November 2023 to June 2024. The inclusion criteria required studies to be randomized clinical trials focusing on pain intensity in instrumental musicians, published in the last 10 years. Two independent researchers assessed the characteristics and methodological quality of the selected studies. Out of 305 identified studies, 15 underwent full-text reviews, with 5 ultimately included in the analysis. The total participant count was 273, with an average intervention duration of 32.5 min per session, twice weekly for eight weeks. Overall, therapeutic exercise interventions demonstrated favorable effects, with three studies exhibiting good methodological quality. The meta-analysis revealed significant positive results favoring exercise in reducing pain intensity, with positive responses observed across all clinical populations, so therapeutic exercise appears to be an effective approach for reducing pain intensity in musicians experiencing playing-related pain.

Unknotting tech neck by breaking the cycle of pain and disability: Comparing the impact of instrument assisted soft tissue mobilization on specific muscles and superficial back arm line

BACKGROUND

Computer professionals often develop a forward head posture due to prolonged hours of computer use, leading to neck pain. Instrument-assisted soft tissue mobilization (IASTM), an advanced technique for treating myofascial trigger points, has become increasingly popular for addressing these musculoskeletal issues.

OBJECTIVES

The study aimed to compare the effectiveness of IASTM mobilization on SBAL (superficial back arm line) and SM(specific muscles-upper trapezius, levator scapulae, and sternocleidomastoid) in managing chronic neck pain among computer professionals.

PARTICIPANTS & METHODS

The study involved 62 computer professionals, randomly divided into two groups. Group A received IASTM on SBAL and group B received IASTM on SM for neck pain each receiving three sessions weekly for four weeks. Outcome variables like Neck Disability Index (NDI), NPRS(Neck Pain Rating Scale), Craniovertebral angle (CVA), and range of motion (ROM) for flexion, and side flexion (right & left side) were evaluated at baseline, 2 weeks and 4 weeks.

RESULTS

Significant improvement in NPRS were observed in both the SBAL and SM groups after 2 weeks of IASTM, wth the SBAL group demonstrating greater improvement. At 4 weeks, IASTM on SBAL showed significantly higher improvements in NPRS, CVA, NDI, and flexion compared to the SM group. The repeated measures ANOVA indicated a significant main effect of both time and group, along with a significant interaction between time and group for all outcome variables, except for CVA.

CONCLUSION

The study indicates that IASTM on SBAL may offer a more effective treatment for chronic neck pain in computer professionals compared to targeting specific muscles.

Moving from the clinic to telehealth during the COVID-19 pandemic - a pilot clinical trial comparing in-clinic rehabilitation versus telerehabilitation for persisting symptoms following a mild Traumatic brain injury

PURPOSE

The objective of this study was to compare the effects of an in-clinic cervicovestibular rehabilitation program (education, home exercises, manual techniques, sub-symptom threshold aerobic exercise [STAE] program) to a similar program (education, home-exercises, STAE program), but without manual techniques, provided in a telerehabilitation format in adults with persisting post-concussion symptoms (PCS).

MATERIALS AND METHODS DESIGN

In this parallel-group non-randomized clinical trial, 41 adults with persisting PCS were allocated to the in-clinic (n = 30) or telerehabilitation (n = 11) program. The outcome measures, which included the Post-Concussion Symptom Scale (PCSS; primary outcome), Numerical Pain Rating Scale (NPRS) for neck pain and headache and three disability questionnaires, were collected at baseline, weeks 6, 12, and 26. Non-parametric analysis for longitudinal data (NparLD) was used.

RESULTS

For the PCSS, there was a group-by-time interaction (p = 0.05) with significant between-group differences at week 6, 12, and 26 (p < 0.05) for the in-clinic group. There were also group-by-time interactions for NPRS neck pain and headache (p < 0.05) for the in-clinic group.

CONCLUSION

The study suggests that a telehealth format failed to reach the efficiency of an in-clinic rehabilitation program in terms of symptoms reduction and functional improvement. These results must be interpreted with caution given the limited number of participants. ClinicalTrials.gov Identifier: NCT03677661.IMPLICATION FOR REHABILITATIONThe telerehabilitation format for adults with persisting post-concussion symptoms was widely implemented in the COVID-19 pandemic without any evidence of efficacy over the more traditional in-clinic rehabilitation format.The study suggests that a telerehabilitation format failed to reach the efficiency of an in-clinic rehabilitation program in terms of symptoms reduction and functional improvement.Clinicians should try to incorporate some in-clinic appointments when a telerehabilitation format is required such as for patients in underserved area.

Efficacy of neck muscle activation versus strengthening for adults with chronic cervical radiculopathy: a study protocol for a randomised clinical trial

Introduction

Chronic cervical radiculopathy is a common condition characterised by neck and arm pain, numbness and weakness. Both neck muscle activation and strengthening exercises are widely recognised treatments for cervical radiculopathy, but there is a research gap on the efficacy of neck muscle activation versus strengthening. This protocol will determine the efficacy of neck muscle activation alongside conventional care versus strengthening exercise and conventional care for cervical radiculopathy.

Methods and analysis

We planned a 5-week parallel, two-arm randomised clinical trial on 80 participants with chronic cervical radiculopathy (lasting over 3 months) between July and December 2023. Participants will be recruited from Dhaka's Agrani Specialised Physiotherapy Centre in Bangladesh and randomly assigned to two groups in a 1:1 ratio. Both groups will receive 14 sessions, each lasting 30-45 min. Post-treatment evaluations will be employed on Brief Pain Inventory (BPI), range of motion, craniovertebral angle (CVA), strength, endurance and Neck Disability Index (NDI) after 5 weeks and follow-up after 12 weeks of post-test analysis. Primary outcomes (strength, endurance and CVA) will be measured using a handheld dynamometer, digital inclinometer and goniometer. Secondary outcomes (pain, range of motion and disability) will be assessed through the BPI scale, digital inclinometer and NDI.

Ethics and dissemination

The Institute of Physiotherapy Rehabilitation and Research of Bangladesh Physiotherapy Association has approved the study. All participants will provide informed consent, and data will be anonymised and accessible only to authorised personnel. The study's findings will be disseminated in peer-reviewed journals and conferences.

Effect of proprioceptive neuromuscular facilitation and cranio-cervical flexor training on pain and function in chronic mechanical neck pain: A randomized clinical trial

BACKGROUND

Chronic neck pain is known to be caused by the weakness of the deep neck flexors and disturbances in the mechanoreceptors and the proprioceptors of the cervical spine. Proprioceptive neuromuscular facilitation (PNF) is hypothesized to balance the relative stiffness and weakness of the muscles and activate the mechanoreceptors and proprioceptors.

OBJECTIVE

To investigate PNF techniques and the craniocervical flexor training (CCFT) techniques for pain and function in chronic neck pain.

METHODS

A randomized clinical trial was conducted on 66 chronic mechanical neck pain patients randomly assigned to either the PNF or CCFT groups using block randomization for a duration of 4 weeks. Numerical Pain Rating Scale (NPRS), Neck disability Index (NDI) and Active cervical range of motion (ACROM) were measured at baseline and after 4 weeks of intervention. Data were analysed using independent t test and MANOVA.

RESULTS

The mean difference scores for NPRS and NDI were 2.18 and 15.72 in PNF group and 2.26 and 15.76 in the CCFT groups, respectively. Both the groups showed a change that was statistically significant. Also, the mean differences for the ACROM in all the planes in both the groups were statistically significant. However, the between group changes did not reveal any statistical significance in this study except for the right rotation in the CCFT group (p = 0.01).

CONCLUSIONS

This study concluded that the PNF treatment is also beneficial to pain and function in treating chronic mechanical neck pain patients as its results stand similar to the CCFT treatment, which is already established to be a reliable tool to treat this condition.

Assessment of Long-term Effects of Adding Osteopathic Manipulative Treatment to Neck Exercises for Individuals With Non-specific Chronic Neck Pain: A Randomized Trial

Objective

The purpose of this study was to evaluate the long-term effects of adding osteopathic manipulative treatment (OMT) to neck exercises compared to exercises alone for individuals with non-specific chronic neck pain (NCNP).

Methods

A randomized controlled trial was conducted by assigning 90 individuals with NCNP into the following 2 groups: (1) exercises group (EG, n = 45) or (2) OMT plus exercises group (OMT/EG, n = 45). All participants received 4 weeks of treatment. The clinical outcomes were recorded at baseline and at 3 and 6 months after the treatment. The primary outcomes were pain and function-Numerical Pain Rating Scale (NPRS), Pressure Pain Threshold, and the Neck Disability Index (NDI). The secondary outcomes included range of motion for cervical spine rotation, Fear-Avoidance Beliefs Questionnaire, and Pain Self-Efficacy Questionnaire.

Results

In comparison to baseline data, both groups had a reduction of NPRS (P < .05) and NDI (P < .05) after the treatment. However, no statistically significant differences in pain intensity or disability were found when OMT/EG was compared to EG alone at 3 months (P = 0.1 and P = 0.2, respectively) and at 6 months (P = 0.4 and P = 0.9, respectively for pain and disability) and no difference was found between OMT/EG and the EG in the secondary outcomes during the same follow-up period (P > .05).

Conclusion

Outcomes of pain and functionality for patients in both groups were improved at 6 months. Our findings show that the combination of OMT and neck exercises for 4 weeks did not improve functionality and reduction of pain in patients with NCNP.

Exercise therapy including the cervical extensor muscles in individuals with neck pain: A systematic review

OBJECTIVE

To review the use (dosage parameters and combination with other therapeutic interventions) of cervical extensor muscle exercises and their effect on pain, disability (primary outcomes), range of motion, endurance and strength (secondary outcomes) in people with neck pain.

DATA SOURCES

An extensive literature search was conducted through MEDLINE (Ovid), Scopus (Elsevier) and Physiotherapy Evidence Database (PEDro) up to May 2023. The reference lists of all included studies and relevant reviews were screened for additional studies.

REVIEW METHODS

Randomised controlled trials reporting the use of cervical extensor muscle exercises (alone or combined) applied to adults with idiopathic or traumatic neck pain were included. Study selection, data extraction and critical appraisal (PEDro assessment scale) were performed by two blinded reviewers. Data extraction included dosage parameters, other modalities combined with these exercises and outcomes.

RESULTS

Thirty-five randomised controlled trails (eight of which were complementary analyses) with 2409 participants fulfilled the inclusion criteria. Twenty-six were of moderate to high quality. In most studies, cervical extensor muscle exercises were combined with various other therapeutic modalities and applied at different dosages. Only two studies (one high and one low quality) specifically assessed their effectiveness. The high-quality study showed significant improvements in neck pain and disability, pressure point threshold and neck mobility after both low load and high load training for 6 weeks.

CONCLUSION

The results suggest cervical extensor muscle exercises may reduce neck pain and disability; however firm conclusions cannot be drawn because of the few studies that addressed this question and the heterogeneity of the dosage parameters.

Immediate effect of craniocervical flexion exercise and Mulligan mobilisation in patients with mechanical neck pain - A randomised clinical trial

Background

Mechanical neck pain (MNP) is one of the most prevalent musculoskeletal pathologies in the present time. Physiotherapy management strategies comprising manual therapy and exercise therapy are routinely administered in patients with MNP.

Objective

To compare the immediate effect of craniocervical flexion (CCF) exercise and Mulligan mobilisation on pain, active cervical range of motion (CROM) and CCF test performance in patients with MNP.

Methods

This prospective, randomised, single-blinded study involved 26 patients with MNP (16 females; mean age; 31 . 12 ± 8 . 40 years) randomised to a single session of active CCF exercise (3 sets of 10 repetitions) or Mulligan mobilisation (3 sets of 6-10 repetitions). Pain intensity was measured on a numerical pain rating scale (NPRS), active CROM was measured using CROM device, and CCF test performance with surface electromyography (EMG) from bilateral sternocleidomastoid (SCM) and anterior scalene (AS) muscles recorded pre- and immediately post-intervention by an assessor blinded to the treatment groups. Mann-Whitney U test was used to analyse between groups and Wilcoxon signed rank test was used to analyse within-group significance for pain and CROM, Cochran-Mantel-Haenszel correlation test was used to analyse the CCF test performance on EMG from the bilateral SCM and AS muscles.

Results

Comparison between pre- and post-intervention readings revealed statistically significant within-group (p < 0 . 05 ) and no between-group significant difference for pain, ROM, and CCF test performance, indicating both interventions were equally effective.

Conclusion

Patients with MNP who received active CCF exercise or Mulligan mobilisation exhibited similar reduction in pain intensity and increased CROM and CCF test performance post-intervention. Surprisingly, AS surface EMG amplitudes were increased post-intervention in both groups warranting further exploration of its role in neck pain.

Effect of acupuncture on pain and substance P levels in middle-aged women with chronic neck pain

Chronic neck pain is a leading health issue affecting a significant proportion of the global population. Multiple treatment options for chronic neck pain include anti-inflammatory drugs and analgesics. Acupuncture has been widely used for the treatment of chronic pain. In this study, we aimed to determine the efficacy of acupuncture for female patients with chronic neck pain. Twenty-three participants were enrolled in the study, and participants waited 4 weeks without acupuncture treatment and then received 4 weeks of treatment. One-way ANOVA with repeated measures was used to determine differences in the visual analogue scale (VAS), neck disability index (NDI), and substance P (SP) over time. The subjects' pain intensity and degree of disability due to neck pain were measured as primary outcomes. SP in the blood was also analyzed as a secondary outcome. There was no significant difference between the VAS score and NDI value of baseline and after 4 weeks waiting. However, there was an improvement in both VAS and NDI after 4 weeks treatment. SP level was decreased after 4 weeks treatment. We could conclude that acupuncture is effective in alleviating chronic neck pain. Moreover, our findings revealed the efficacy of acupuncture on chronic pain with potential underlying biological mechanisms.

The effectiveness of aerobic versus strengthening exercise therapy in individuals with chronic whiplash-associated disorder: a randomised single case experimental design study

PURPOSE

Recent RCTs and meta-analyses compare the effectiveness of different types of exercise for chronic whiplash associated disorder (WAD). This study aimed to verify whether the results of these studies translate to statistically significant and clinically meaningful effects in individual participants.

MATERIALS AND METHODS

A series of replicated randomised single case experimental design studies (SCEDs) with A-B design (A: baseline, B: intervention). Eight participants with chronic WAD (8 female, mean [SD] age 47 [10] years) were randomised into one of four baseline durations (5, 8, 11, and 14 days) and to one of two eight-week exercise interventions (aerobic or strengthening). Daily measures of pain intensity, bothersomeness, and interference were collected during the baseline phase and the intervention phase.

RESULTS

Visual analyses indicated that three participants in the aerobic exercise group meaningfully improved. No improvements were found in the strengthening group. Effect sizes favoured the aerobic exercise group, yet randomisation tests of pooled effects did not show a difference in between-intervention effectiveness.

CONCLUSION

Contrary to our expectations, three out of four participants were nearly pain-free at the end of the aerobic exercise intervention, whereas none of the participants in the strengthening group improved meaningfully. This suggests that aerobic exercise may be favourable for WAD.Implications for RehabilitationOur results suggest that aerobic exercises are favourable over strengthening exercises and may be the preferred option for patients with chronic WAD.We found substantial variability in self-reported outcomes within participants, clinicians should be aware of this in the judgement of treatment effectiveness.

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.

Protocol for the development of a 'trustworthy' living systematic review and meta analyses of manual therapy interventions to treat neuromusculoskeletal impairments

BACKGROUND

Preprocessed research resources are believed to be highly 'trustworthy' when translating research to clinical practice. However, the overall 'trustworthiness' is unknown if this evidence contains randomized clinical trials (RCTs) where prospective has not been/cannot be verified, has low confidence in estimated effects, and if they are not up to date.

OBJECTIVES

This protocol will be used to create a baseline benchmark for a series of trustworthy living systematic reviews (SRs) regarding manual therapy interventions.

METHODS

Data will originate from RCTs related to manual therapy neuromusculoskeletal interventions, indexed in 6 search engines in English from 1 January 2010, to the present. Two blinded reviewers will identify the RCTs and extract data using Covidence. The data will be synthesized based on consensus and analyzed using the Cochrane collaboration's Review Manager.

EXPECTED OUTCOMES

It is expected that there will be a shortage of RCTs with at least a moderate confidence in estimated effects that will allow for strong practice recommendations.

DISCUSSION

Identifying evidence that can be translated into strong practice recommendations is essential to identify beneficial and harmful interventions, decrease practice variability, and identify neuromusculoskeletal manual therapy interventions that require further disciplined methodological focus.

Manual therapy for non-radicular cervical spine related impairments: establishing a 'Trustworthy' living systematic review and meta-analysis

OBJECTIVES

To establish a 'trustworthy' living systematic review (SR) with a meta-analysis of manual therapy for treating non-radicular cervical impairments.

DESIGN

SR with meta-analysis.

LITERATURE SEARCH

Articles published between January 2010 and September 2022 were included from: Cochrane Central Register of Controlled Trials (CENTRAL); CINAHL; MEDLINE; PubMed; PEDro, and ProQuest Nursing and Allied Health.

METHODS

This SR included English-language randomized clinical trials (RCTs) of manual therapy involving adults used to treat non-radicular cervical impairments. The primary outcomes were pain and region-specific outcome measures. Cervicogenic headaches and whiplash were excluded to improve homogeneity. Two reviewers independently assessed RCTs. The prospective plan was to synthesize results with high confidence in estimated effects using GRADE.

RESULTS

Thirty-five RCTs were screened for registration status. Twenty-eight were not registered or registered prospectively. In 5 studies, the discussion and conclusion did not match the registry, or this could not be determined. One study did not meet the external validity criterion, and another was rated as having a high risk of bias. One study met the inclusion and exclusion criteria, so practice recommendations could not be made. The remaining study did not identify any clinically meaningful group differences.

DISCUSSION

Only one prospectively registered RCT met this SR's strict, high-quality standards. The single identified paper provides initial high-quality evidence on this topic.

CONCLUSION

This SR establishes a foundation of trustworthiness and can be used to generate research agendas to determine the potential clinical utility of manual therapy directed at the cervical spine for non-radicular cervical complaints.

Effectiveness of McKenzie approach and segmental spinal stabilization exercises on neck pain in individuals with cervical postural syndrome: An experimental study

BACKGROUND

This study "Effectiveness of Mckenzie approach and segmental spinal stabilization exercises on neck pain in individuals with cervical postural syndrome: an experimental study" was conducted to study and find the effectiveness of Mckenzie approach and segmental spinal stabilization exercises on reduction of pain, correction of rounded shoulder, and disability. Pain, disability, and rounded shoulders are the major limiting factors as it affects the quality of life and reduces efficiency and social participation.

MATERIALS AND METHODS

The study was conducted among 120 individuals with cervical postural syndrome, and fulfilling the inclusion and exclusion criteria was included. The outcome measures were Visual Analogue Scale (VAS), Neck Disability Index (NDI), and Vernier caliper to evaluate pain, functional disability, and rounded shoulder, respectively. Subjects were randomly divided into two groups, Group A and Group B, by using SPSS software. Interventional training was given for 6 weeks to the patients. Group A subjects were given spinal stabilization exercises. Group B subjects were given Mckenzie approach. The statistical analysis was performed using SPSS; pre-test and post-test were used to calculate the results, followed by data presentation and analysis.

RESULT

The result showed that at the end of the 6 weeks on comparison between pre- and post-intervention of Group A and Group B, both the techniques were effective, but group B was significantly effective than Group A.

CONCLUSION

It was noted that McKenzie approach and segmental spinal stabilization exercises were effective on neck pain in individuals with cervical postural syndrome, but on comparing both techniques, Mckenzie protocol is more beneficial than segmental spinal stabilization exercises. The study accepts the alternate hypothesis that there is significant effect of McKenzie approach and segmental spinal stabilization exercises on neck pain in individuals with cervical postural syndrome.

Role of non‑coding RNAs in cartilage endplate (Review)

Cartilage endplate (CEP) degeneration is considered one of the major causes of intervertebral disc degeneration (IDD), which causes non-specific neck and lower back pain. In addition, several non-coding RNAs (ncRNAs), including long ncRNAs, microRNAs and circular RNAs have been shown to be involved in the regulation of various diseases. However, the particular role of ncRNAs in CEP remains unclear. Identifying these ncRNAs and their interactions may prove to be is useful for the understanding of CEP health and disease. These RNA molecules regulate signaling pathways and biological processes that are critical for a healthy CEP. When dysregulated, they can contribute to the development disease. Herein, studies related to ncRNAs interactions and regulatory functions in CEP are reviewed. In addition, a summary of the current knowledge regarding the deregulation of ncRNAs in IDD in relation to their actions on CEP cell functions, including cell proliferation, apoptosis and extracellular matrix synthesis/degradation is presented. The present review provides novel insight into the pathogenesis of IDD and may shed light on future therapeutic approaches.

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.

Effects of manual therapy combined with therapeutic exercise versus routine physical therapy on brain biomarkers in patients with chronic non-specific neck pain in Thailand: a study protocol for a single-blinded randomised controlled trial

INTRODUCTION

Structural brain alterations in pain-related areas have been demonstrated in patients with non-specific neck pain. While manual therapy combined with therapeutic exercise is an effective management for neck pain, its underlying mechanisms are poorly understood. The primary objective of this trial is to investigate the effects of manual therapy combined with therapeutic exercise on grey matter volume and thickness in patients with chronic non-specific neck pain. The secondary objectives are to assess changes in white matter integrity, neurochemical biomarkers, clinical features of neck pain, cervical range of motion and cervical muscle strength.

METHODS AND ANALYSIS

This study is a single-blinded, randomised controlled trial. Fifty-two participants with chronic non-specific neck pain will be recruited into the study. Participants will be randomly allocated to either an intervention or control group (1:1 ratio). Participants in the intervention group will receive manual therapy combined with therapeutic exercise for 10 weeks (two visits per week). The control group will receive routine physical therapy. Primary outcomes are whole-brain and regional grey matter volume and thickness. Secondary outcomes are white matter integrity (fractional anisotropy and mean diffusivity), neurochemical biomarkers (N-acetylaspartate, creatine, glutamate/glutamine, myoinositol and choline), clinical features (neck pain intensity, duration, neck disability and psychological symptoms), cervical range of motion and cervical muscle strength. All outcome measures will be taken at baseline and postintervention.

ETHICS AND DISSEMINATION

Ethical approval of this study has been granted by Faculty of Associated Medical Science, Chiang Mai University. The results of this trial will be disseminated through a peer-reviewed publication.

A systematic review and meta-analysis of randomized controlled trials of manipulative therapy for patients with chronic neck pain

BACKGROUND

An increasing number of people suffer from chronic neck pain due to increased telecommuting. Manual therapy is considered a safe and less painful method and has been increasingly used to alleviate chronic neck pain. However, there is controversy about the effectiveness of manipulation therapy on chronic neck pain. Therefore, this systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to determine the effectiveness of manipulative therapy for chronic neck pain.

METHODS

A search of the literature was conducted on seven databases (PubMed, Cochrane Center Register of Controlled Trials, Embase, Medline, CNKI, WanFang, and SinoMed) from the establishment of the databases to May 2022. This study included RCTs on chronic neck pain managed with manipulative therapy compared with sham, exercise, and other physical therapies. The retrieved records were independently reviewed by two researchers. Further, the methodological quality was evaluated using the PEDro scale. All statistical analyses were performed using RevMan V.5.3 software. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) assessment was used to evaluate the quality of the study results.

RESULTS

Seventeen RCTs, including 1190 participants, were included in this meta-analysis. Manipulative therapy showed better results regarding pain intensity and neck disability than the control group. Manipulative therapy was shown to relieve pain intensity (SMD = -0.83; 95% confidence interval [CI] = [-1.04 to -0.62]; p < 0.0001) and neck disability (MD = -3.65; 95% CI = [-5.67 to - 1.62]; p = 0.004). However, the studies had high heterogeneity, which could be explained by the type and control interventions. In addition, there were no significant differences in adverse events between the intervention and the control groups.

CONCLUSIONS

Manipulative therapy reduces the degree of chronic neck pain and neck disabilities.

Comparison of two different manual techniques for an exercise program for the management of chronic neck pain: A randomized clinical trial study

BACKGROUND

Both spinal manipulation (SM) and Integrated Neuromuscular Inhibition Technique (INIT) have a positive effect in individuals with chronic neck pain (CNP), especially when they are combined with therapeutic exercise (TE). However, it has not been determined which of the above combinations is more effective in patients with CNP.

OBJECTIVE

To compare the efficacy of two different manual techniques (SM and INIT), when combined with the same TE program in the management of CNP.

METHODS

Eighty women with CNP, allocated into four groups of 20 persons each. The first group followed a 10-week TE program, the second TE and INIT, the third TE and SM, and the fourth was the control group. The Visual Analogue Scale (VAS) for pain, Neck Disability Index (NDI), Pressure Pain Threshold (PPT) of the neck muscles, neck active Range of Motion (ROM), Maximum Isometric Strength (MIS) of the neck muscles, craniocervical flexion test (CCFT) and SF-36 questionnaire scores were evaluated before, during and after the treatment period, with a six-month follow-up.

RESULTS

There was between groups differences between the three intervention groups and the control group (p< 05), with the positive effects being maintained until the six-month follow-up. However, this improvement occurred earlier in the "TE + INIT" and "TE + SM" groups than in the "TE" group. Differences between the "TE + INIT" and the "TE + SM" groups were noticed only in the neck muscles PPT values, in which the "TE + INIT" group showed greater improvement. Furthermore, some non-statistically significant indications for further improvement of "TE + SM" were noted in the left lateral flexion ROM.

CONCLUSION

The addition of INIT as well as SM in the same TE program can further increase the beneficial effect of exercise in women with CNP. In most measurements both combinations seem to be equally effective. However, INIT improved more local muscle tenderness, whereas SM aided more in the neck lateral flexion ROM.

Global trends in research on cervicogenic headache: a bibliometric analysis

Background

There has been a marked increase in cervicogenic headaches in recent years, significantly affecting sufferers' daily lives and work. While several treatments exist for this type of headache, their long-term effects could be improved, and additional data from large clinical samples are needed. This study aims to systematically examine the current state of research in cervicogenic headaches through a bibliometric analysis, identify areas of current interest, and provide insight into potential future research directions.

Methods

This article examines research trends in the field of cervicogenic headache through a bibliometric analysis of scholarly articles in the field of cervicogenic headache over the past four decades. The bibliometric analysis method employed included searching the Web of Science database using topics related to cervicogenic headaches. Inclusion criteria were limited to articles and review papers on cervicogenic headaches published between 1982 and 2022. The retrieved dataset was then analyzed using R software and VOSviewer to identify the major research areas, countries and institutions, the most influential authors, journals and keywords, co-citations in the literature, and co-authorship networks.

Results

This study analyzed 866 articles published between 1982 and 2022, involving 2,688 authors and generating 1,499 unique author keywords. Neuroscience and neurology were the primary focus, with participation from 47 countries, primarily led by the United States, which has the most published articles (n = 207), connections (n = 29), and citations (n = 5,238). In the cervicogenic headache study, which involved 602 institutions, the University of Queensland received the most significant number of citations (n = 876), and Cephalalgia was the journal with the most published articles and received the most local citations (n = 82) and highest growth (n = 36). Two hundred sixty-nine journals have published articles on cervicogenic headaches. Among researchers studying cervicogenic headache, Sjaastad O had the most published articles (n = 51) and citations (n = 22). The most commonly occurring keyword was "cervicogenic headache." Except for the fourth most impactful paper, as determined by the Local Citation Score, which analyzed clinical treatments, all the top documents emphasized investigating the diagnostic mechanisms of cervicogenic headache. The most commonly occurring keyword was "cervicogenic headache."

Conclusion

This study used bibliometric analysis to provide a comprehensive overview of the current research on cervicogenic headaches. The findings highlight several areas of research interest, including the need for further investigation into the diagnosis and treatment of cervicogenic headaches, the impact of lifestyle factors on cervicogenic headaches, and the development of new interventions to improve patient outcomes. By identifying these gaps in the literature, this study provides a foundation for guiding future research to improve the diagnosis and treatment of cervicogenic headaches.

Evaluation of single session physical therapy methods in bruxism patients using shear wave ultrasonography

OBJECTIVE

To compare the immediate effects of a single session of manual therapy (MT) or Kinesio taping following MT (KTMT) in patients with bruxism using shear wave ultrasonography.

METHODS

Twenty patients were included in the MT group (mean age 27.3 ± 4.8), and 19 patients were included in the KTMT group (age mean 26.2 ± 5.4), randomly. Muscle thickness and stiffness were assessed via shear wave ultrasonography, and pain pressure threshold was assessed with an algometer before and after one session of MT or KTMT.

RESULTS

Significant decreases were found in muscle thickness and stiffness of the bilateral masseter (p < 0.05). Significant decrease in pain was seen in the masseter and temporalis muscle PPT measurements in the KTMT group (p < 0.05) only.

CONCLUSION

Kinesio taping in addition to MT is recommended in the immediate physiotherapy treatment of bruxism for acute pain.

The effect of exercise on health-related quality of life in persons with musculoskeletal pain: A meta-analysis of randomised control trials

OBJECTIVES

Exercise has positive effects on musculoskeletal pain. In this project, the impact of exercise was studied on improving health-related quality of life in persons with musculoskeletal pain.

METHOD

The study design was a systematic review and meta-analysis. A search was conducted to find original studies in four sources, including PubMed, Web of Science, the Cochrane Library and Scopus, and this search was limited to the original articles published until April 2021, which were in English. For each study, the effect size was calculated. The analysis was based on the random-effects method.

RESULT

Twenty-Seven randomised control trial studies were included in the meta-analysis. The total population of participants in the meta-analysis was 1927 persons. Exercise improves health-related quality of life in these persons and the hedges' g was 0.66 (95% CI = 0.38-0.94; I²  = 88.29%).

DISCUSSION

Overall, based on the findings, exercise is associated with improving the health-related quality of life of persons with musculoskeletal pain, and therefore the health implications of this finding are beneficial to the general population and professionals.

Analysis of cervical and upper thoracic spinal segmental rotation angles during end-range neck rotation: Comparison with and without neck pain

BACKGROUND

Neck pain is a common manifestation of musculoskeletal disorders of the cervical and thoracic spine. Manual therapy interventions to the thoracic spine are recommended for treating patients with several types of neck pain. However, only a few studies have investigated the thoracic spine mobility associated with neck movement.

OBJECTIVES

Compare cervical and upper thoracic rotation angles in subjects with and without neck pain.

METHODS

The subjects included nine individuals who experienced neck pain (pain, Group P) and 11 who did not (non-pain, Group N). The rotation angle was measured using MRI. The imaging limb position was at 90% of the maximum neck rotation. The MR images were analyzed using image analysis software to calculate the rotation angle of C1 to Th3. The rotation angle of the segment was then calculated by subtracting the rotation angle corresponding to the lower vertebra from that corresponding to the upper vertebra. The total rotation of each segment was calculated as the sum of the right and left rotation angle. Then, the segmental rotation angles were compared between groups.

RESULTS/FINDINGS

The rotation angles of C3-C4, C7-Th1, and Th1-Th2 were significantly smaller in Group P than in Group N, and C5-C6 and C6-C7 were significantly larger in Group P than in Group N. There was no statistical difference in rotational angle at all other spinal levels measured.

CONCLUSIONS

The results of this study indicate subjects with neck pain had hypermobility of the lower cervical spine and hypomobility of the cervico-thoracic junction and upper thoracic spine compared with subjects without neck pain. These results add to current understanding of biomechanical factors that may be related to neck pain.

Evidence (-based medicine) in manual medicine/manual therapy—a summary review

Objective

The aim of this summary review is to analyse the current state of evidence in manual medicine or manual therapy.

Methods

The literature search focussed on systematic reviews listed in PubMed referring to manual medicine treatment until the beginning of 2022, limited to publications in English or German. The search concentrates on (1) manipulation, (2) mobilization, (3) functional/musculoskeletal and (4) fascia. The CASP Checklist for Systematic Reviews was used to present the included reviews in a clear way.

Results

A total of 67 publications were included and herewith five categories: low back pain, neck pain, extremities, temporomandibular disorders and additional effects. The results were grouped in accordance with study questions.

Conclusion

Based on the current systematic reviews, a general evidence-based medicine level III is available, with individual studies reaching level II or Ib. This allows manual medicine treatment or manual therapy to be used in a valid manner.

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.

Effects of Cervical Spine Exercise Protocol on Neck Pain, Pericervical Muscle Endurance, and Range of Motion in Medical Students: A Prospective Study

Introduction

Neck pain is a common and debilitating ailment that places a significant burden on the healthcare system. No practical protocols have been published utilizing a portable, commercially available, and affordable device that significantly reduces acute and chronic neck pain.

Methods

Forty-six young adults with or without mild-to-moderate neck pain completed a six-week neck stretching and strengthening protocol with a portable cervical stretching and strengthening device. The primary outcome was changes to pericervical muscle endurance. Secondary outcomes were changes to cervical range of motion (ROM), neck length, circumference, and subjective pain, flexibility, and strength. Measurements were obtained on study days 0, 21, and 42.

Results

A significant increase in pericervical muscle endurance was demonstrated across all planes of cervical motion, ranging from 84% to 105%. Cervical ROM improved across all planes of motion but was only significant in right-side bending (5.3°), left rotation (6.2°), and right rotation (7.8°). Subjective pain evaluated via the Numeric Rating Scale (NRS) saw statistically significant improvement as well (1.33 to 0.51). Subjective assessment of participant cervical pain, strength, and flexibility improved 61.3%, 95.7%, and 97.8%, respectively.

Conclusions

A six-week pericervical muscle stretching and strengthening program increased pericervical endurance and ROM in young adults. Decreased cervical pain was seen using the NRS and modified pain scale across most participants.

A Single-Center Study Comparing the Effects of Thoracic Spine Manipulation vs Mobility Exercises in 26 Office Workers with Chronic Neck Pain: A Randomized Controlled Clinical Study

Background

Neck pain is associated with computer work, poor posture, imbalanced neck muscles, and fatigue, particularly in office workers. This study from a single center aimed to compare the effects of thoracic spine mobility exercise and thoracic spine manipulation to improve cervical spine range of motion in 26 office workers who had chronic neck pain for more than 12 weeks.

Material/Methods

The participants were 26 office workers with neck pain lasting >12 weeks. These participants were randomly assigned to undergo TSME (n=13) or TSM (n=13). Both groups underwent cervical joint mobilization and deep cervical flexor muscle exercises for 25 min a day, twice weekly, for 6 weeks. The TSME group additionally performed TSME 15 min a day, twice a week, for 6 weeks, while the TSM group received TSM 2 times a day, twice a week, for 6 weeks. Cervical and thoracic spine ROM, numeric pain rating scale (NPRS), and neck disability index (NDI) were measured before and after interventions. The ROM of cervical and thoracic spine was measured using a dual inclinometer.

Results

Both groups showed significant changes in cervical spine ROM, thoracic spine ROM, NPRS, and NDI after intervention compared to before intervention (P<0.05). Cervical spine right lateral flexion and right rotation differed significantly between the groups (P<0.05), while thoracic spine ROM, NPRS, and NDI did not.

Conclusions

TSME and TSM have similar effects in improving pain and disability in office workers with non-specific chronic neck pain.

Health Care Resource Utilization in Management of Opioid-Naive Patients With Newly Diagnosed Neck Pain

IMPORTANCE

Research has uncovered heterogeneity and inefficiencies in the management of idiopathic low back pain, but few studies have examined longitudinal care patterns following newly diagnosed neck pain.

OBJECTIVE

To understand health care utilization in patients with new-onset idiopathic neck pain.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used nationally sourced longitudinal data from the IBM Watson Health MarketScan claims database (2007-2016). Participants included adult patients with newly diagnosed neck pain, no recent opioid use, and at least 1 year of continuous postdiagnosis follow-up. Exclusion criteria included prior or concomitant diagnosis of traumatic cervical disc dislocation, vertebral fractures, myelopathy, and/or cancer. Only patients with at least 1 year of prediagnosis lookback were included. Data analysis was performed from January 2021 to January 2022.

MAIN OUTCOMES AND MEASURES

The primary outcome of interest was 1-year postdiagnosis health care expenditures, including costs, opioid use, and health care service utilization. Early services were those received within 30 days of diagnosis. Multivariable regression models and regression-adjusted statistics were used.

RESULTS

In total, 679 030 patients (310 665 men [45.6%]) met the inclusion criteria, of whom 7858 (1.2%) underwent surgery within 1 year of diagnosis. The mean (SD) age was 44.62 (14.87) years among nonsurgical patients and 49.69 (9.53) years among surgical patients. Adjusting for demographics and comorbidities, 1-year regression-adjusted health care costs were $24 267.55 per surgical patient and $515.69 per nonsurgical patient. Across all health care services, $95 379 949 was accounted for by nonsurgical patients undergoing early imaging who did not receive any additional conservative therapy or epidural steroid injections, for a mean (SD) of $477.53 ($1375.60) per patient and median (IQR) of $120.60 ($20.70-$452.37) per patient. On average, patients not undergoing surgery, physical therapy, chiropractic manipulative therapy, or epidural steroid injection, who underwent either early advanced imaging (magnetic resonance imaging or computed tomography) or both early advanced and radiographic imaging, accumulated significantly elevated health care costs ($850.69 and $1181.67, respectively). Early conservative therapy was independently associated with 24.8% (95% CI, 23.5%-26.2%) lower health care costs.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, early imaging without subsequent intervention was associated with significantly increased health care spending among patients with newly diagnosed idiopathic neck pain. Early conservative therapy was associated with lower costs, even with increased frequency of therapeutic services, and may have reduced long-term care inefficiency.

Cervical facet joint platelet-rich plasma in people with chronic whiplash-associated disorders: A prospective case series of short-term outcomes

Objective

To explore the safety and feasibility of a single autologous injection of platelet-rich plasma (PRP) in cervical facet joints of people with chronic WAD and facet-mediated pain, and explore the association between pain relief reported with diagnostic medial branch blocks (MBBs) and 3-months post-PRP.

Design

A prospective case series of people with chronic whiplash-associated disorders and cervical facet joint mediated pain in a community setting.

Interventions

A single autologous PRP injection was provided to cervical facet joints under ultrasound and fluoroscopic guidance.

Measures

Adverse events were recorded one-week, and measures of pain (numerical pain rating scale - NPRS) and disability (Neck Disability Index - NDI) were collected prior to and 3-months following cervical facet joint PRP. People not reached for follow-up were considered failures for worst-case analysis. The correlation between percentage response to diagnostic cervical medial branch blocks (MBBs) and percentage pain relief reported at 3-months was also investigated.

Results

Forty-four people (82% female; mean age (SD): 45.2 (10.8) years) underwent cervical facet joint PRP. There was a significant improvement in pain and disability following PRP. Seventy percent of people exceeded MCID for pain. For NDI scores, 80% of people exceeded MCID. Forty-one percent of people reported greater than 50% relief of pain 3-months post-cervical facet joint PRP.There was no significant correlation between percentage relief of pain with cervical MBBs and percentage relief of pain 3-months post-PRP (r ​= ​0.06, p ​= ​0.73).There were no adverse events reported.

Conclusion

In people with chronic WAD and facet-mediated pain, preliminary data suggests that PRP is safe and it is feasible to move forwards with randomized studies to further investigate efficacy and effectiveness.

Two Distinct Neural Mechanisms Underlying Acupuncture Analgesia

Acupuncture analgesia is a traditional treatment with a long history, although it lacks scientific evidence. It is reportedly associated with the central nervous system, including various brain regions, from the cortices to the brain stem. However, it remains unclear whether the distributed regions behave as a single unit or consist of multiple sub-units playing different roles. Magnetoencephalography is a neuroimaging technique that can measure the oscillatory frequency of neural signals and brain regions. The frequency band of neural signals allows further understanding of the characteristics of the acupuncture-related neural systems. This study measured resting-state brain activity using magnetoencephalography in 21 individuals with chronic pain before and after acupuncture treatment. The subjective level of pain was assessed using a visual analog scale, and brain activity was compared to identify the brain regions and the frequencies associated with acupuncture analgesia. Here, we categorized the changes in resting-state brain activity into two groups: low-frequency oscillatory activity (&lt;3 Hz) in the left middle occipital and right superior partial lobule and high-frequency oscillatory activity (81–120 Hz) on both sides of the prefrontal, primary sensory, and right fusiform gyri. These findings suggest that acupuncture analgesia influences two or more sub-units of the neural systems, which helps us understand the neural mechanisms underlying acupuncture analgesia.

Is Cervical Stabilization Exercise Immediately Effective in Patients with Chronic Neck Pain and Upper Cervical Spine Dysfunction? Randomized Controlled Trial

Purpose: To compare the effectiveness of a single exercise session with manual therapy techniques in the segments of the upper cervical spine (C0−1, C1−2 and C2−3), against a single exercise session in patients with chronic neck pain and mobility deficits in the upper cervical spine. Methods: A single-blind randomized controlled trial was performed. Fifty-eight patients were recruited (29 for the manual therapy and exercise group and 29 for the exercise group) who presented chronic neck pain and upper cervical spine dysfunction. The exercise focused on the deep muscles. The manual therapy combined manipulations and mobilizations with these exercises. Cervical range of motion, flexion-rotation test, pressure pain threshold and pain intensity were measured by a blind evaluator before and after the intervention. Results: Compared to pre-intervention, after intervention, the exercise group was significantly lower in terms of the range of motion, flexion-rotation test, and pressure pain threshold (p < 0.05). The manual therapy and exercise group improved in upper cervical flexion, the flexion-rotation test and intensity of pain (p < 0.05). Conclusions: It may be necessary to normalize the mobility of the upper cervical spine before cervical stabilization training, in patients with chronic neck pain and mobility deficits in the upper cervical spine.

Systematic review and meta-analysis of the therapeutic management of patients with cervicogenic dizziness

BACKGROUND

Patients with cervicogenic dizziness (CGD) present with dizziness, cervical spine dysfunctions, and postural imbalance, symptoms that can significantly impact their daily functioning.

OBJECTIVES

To provide evidence-based recommendations for the management of patients with CGD.

METHODS

Three databases were searched for randomized controlled trials (RCTs) (last search 15 May 2021). Outcome measures included dizziness, cervical spine, and balance parameters. Cochrane standard methodological procedures were used and included the RoB 2.0 and GRADE. Where possible, RCTs were pooled for meta-analysis.

RESULTS

Thirteen RCTs (n = 898 patients) of high (two RCTs), moderate (five RCTs), and low (six RCTs) methodological quality were analyzed. Six RCTs were included in the meta-analysis. Only three RCTs specified the cause of CGD. They showed inconsistent findings for the effectiveness of exercise therapy in patients with traumatic CGD. Manual therapy and manual therapy combined with exercise therapy may reduce CGD, cervical spine, and balance dysfunctions.

CONCLUSION

There is moderate quality of evidence that manual therapy reduces CGD, cervical spine, and balance symptoms. When manual therapy is combined with exercise therapy, the positive effect on CGD, cervical spine, and balance symptoms is even stronger. However, the quality of the evidence here is very low.

Cervicovestibular Rehabilitation in Adults with Mild Traumatic Brain Injury: A Randomised Clinical Trial

The objective of this study was to compare the effects of a cervicovestibular rehabilitation program combined with symptom-limited aerobic exercise (SLAE) program to a SLAE program alone in adults with persistent symptoms following mild traumatic brain injury (mTBI) on severity of symptoms and other indicators of clinical recovery. In this single-blind, parallel-group randomised clinical trial, 60 adults with persistent symptoms following mTBI were randomly assigned to: 1) a 6-week SLAE program or 2) a 6-week cervicovestibular rehabilitation program combined with SLAE program. All participants took part in 4 evaluation sessions (baseline, week 6, 12 and 26) performed by a blinded evaluator. The primary outcome was the Post-Concussion Symptoms Scale (PCSS). The secondary outcomes were Numerical Pain Rating Scale (NPRS), Neck Disability Index (NDI), Headache Disability Inventory (HDI), Dizziness Handicap Inventory (DHI), time to return to function, and physical cervical and vestibular measures. Nonparametric analysis for longitudinal data was used to evaluate the effect of interventions on outcomes. For PCSS, NPRS, NDI, HDI, DHI and return to function, there were no group-by-time interactions at any time-points follow-up (p>0.05); clinically significant time effects were however observed (p0.05). There were group-by-time interactions at weeks 6 and 12 for vestibulo-ocular reflex (p0.003) and the cranio-vertebral mobility (p0.001) measures in favor of the cervicovestibular rehabilitation group. The study indicates that a cervicovestibular rehabilitation program combined with SLAE was not superior to a SLAE program alone in term of symptoms and functional level improvement but resulted in improved physical cervical and vestibular function. Keywords: mild traumatic brain injury, rehabilitation, neck pain, dizziness, headache.

Effect of Combined Manual Therapy and Therapeutic Exercise Protocols on the Postural Stability of Patients with Non-Specific Chronic Neck Pain. A Secondary Analysis of Randomized Controlled Trial

Postural stability is a little-studied factor in non-specific chronic neck pain; the causes that can alter it are unknown. The relationship with chronic pain could be a determining factor for its deficit. The aim of this study was to investigate the relationship between sustained pain and a postural stability deficit. A randomized and blinded clinical trial (double-blind; placebo control; 12 weeks follow-up) was conducted with a total of 69 subjects divided into three groups, two experimental (manual therapy and specific exercise) and a control treatment, and carried out over a treatment period of three weeks with a follow-up after 12 weeks. Their postural stability was assessed through the overall balance index (OBI). The postural stability of subjects with non-specific chronic neck pain improved in the experimental treatments. There were no statistically significant differences between the experimental groups. This trial found that manual therapy and therapeutic exercise significantly improved OBI compared to the control group. Trial registration: Brazilian Clinical Trial Registry, RBR-2vj7sw.

Comparison of an exercise program with and without manual therapy for patients with chronic neck pain and upper cervical rotation restriction. Randomized controlled trial

Background

Cervical exercise has been shown to be an effective treatment for neck pain, but there is still a need for more clinical trials evaluating the effectiveness of adding manual therapy to the exercise approach. There is a lack of evidence on the effect of these techniques in patients with neck pain and upper cervical rotation restriction.

Purpose

To compare the effectiveness of adding manual therapy to a cervical exercise protocol for the treatment of patients with chronic neck pain and upper cervical rotation restriction.

Methods

Single-blind randomized clinical trial. Fifty-eight subjects: 29 for the Manual Therapy+Exercise (MT+Exercise) Group and 29 for the Exercise group. Neck disability index, pain intensity (0–10), pressure pain threshold (kPa), flexion-rotation test (°), and cervical range of motion (°) were measured at the beginning and at the end of the intervention, and at 3-and 6-month follow-ups. The MT+Exercise Group received one 20-min session of manual therapy and exercise once a week for 4 weeks and home exercise. The Exercise Group received one 20-min session of exercise once a week for 4 weeks and home exercise.

Results

The MT+Exercise Group showed significant better values post-intervention in all variables: neck disability index: 0% patient with moderate, severe, or complete disability compared to 31% in the Exercise Group (p = 0.000) at 6-months; flexion-rotation test (p = 0.000) and pain intensity (p = 0.000) from the first follow-up to the end of the study; cervical flexion (p = 0.002), extension (p = 0.002), right lateral-flexion (p = 0.000), left lateral-flexion (p = 0.001), right rotation (p = 0.000) and left rotation (p = 0.005) at 6-months of the study, except for flexion, with significative changes from 3-months of follow up; pressure pain threshold from the first follow-up to the end of the study (p values range: 0.003–0.000).

Conclusion

Four 20-min sessions of manual therapy and exercise, along with a home-exercise program, was found to be more effective than an exercise protocol and a home-exercise program in improving the neck disability index, flexion-rotation test, pain intensity, and pressure pain threshold, in the short, medium, and medium-long term in patients with chronic neck pain and upper rotation restriction. Cervical range of motion improved with the addition of manual therapy in the medium and medium-long term. The high dropout rate may have compromised the external validity of the study.

Comparison of Kinesio Taping and manual therapy in the treatment of patients with bruxism using shear-wave elastography-A randomised clinical trial

BACKGROUND

Bruxism is significantly associated with craniofacial pain, feeling of stiffness or fatigue of the jaw and neck pain. Various physiotherapeutic strategies are used in the treatment of bruxism; however, it is not clear which method leads to greater decrease in pain.

OBJECTIVE

The aim of this study is to compare the effects of two physiotherapy methods (manual therapy [MT] and Kinesio taping with manual therapy [KTMT]) in patients with bruxism.

METHODS

Patients were randomised into MT or KTMT groups. Evaluations were performed at baseline and following 4 weeks of physiotherapy. Muscle thickness and stiffness were assessed via shear wave elastography; pain thresholds were evaluated using algometer. Sleep quality was assessed using Pittsburgh Sleep Quality Index, and quality of life was assessed with Likert scales regarding the associated symptoms.

RESULTS

Significant decreases were found in muscle stiffness, pain threshold, sleep quality and quality of life (P < .05) in both MT and KTMT groups. Pain in bilateral temporalis and right occipital region of the trapezius muscle decreased more in the KTMT group compared with the MT group (P < .05). No significant differences in muscle thickness (P > .05) were found in either of the groups.

CONCLUSION

Both MT and KTMT methods were effective in the treatment of bruxism. Kinesio Tape used in conjunction with MT has additionally decreased jaw pain and temporal region pain compared with MT intervention only. Therefore, if jaw pain is the primary complaint of a patient, our results recommend including Kinesio Tape application in the physiotherapeutic treatment program.

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.

Effects of Sling-Based Thoracic Active Exercise on Pain and Function and Quality of Life in Female Patients with Neck Pain: A Randomized Controlled Trial

This study aimed to investigate the effects of sling-based thoracic active exercise on pain, function, and quality of life in female patients with neck pain. A total of 27 female patients with neck pain were divided into the sling-based thoracic active exercise group (n = 14) and the control group (n = 13). The study group performed a sling-based thoracic active exercise with cervical manual therapy for 50 min a day, twice a week for 4 weeks, whereas the control group performed a placebo exercise with cervical manual therapy in the same manner as the study group. Evaluation of the degree of pain before and after treatment was based on the pressure pain threshold and numeric pain rating scale scores. The craniovertebral angle and neck disability index (NDI) were used to evaluate neck function, and quality of life was measured using the Short Form-36. Afterwards, the patients’ pressure pain thresholds were significantly increased, and the numeric pain rating scale score was significantly decreased in both groups (p < 0.05). In terms of function, the craniovertebral angle was significantly increased in both groups (p < 0.05), and neck dysfunction significantly decreased (p < 0.05). The quality of life significantly increased in both groups (p < 0.05). The pressure pain threshold, craniovertebral angle, neck dysfunction index, and quality of life scores (p < 0.05) were significantly different between groups, except the numeric pain scale score. Our results showed that sling-based thoracic active exercise is effective in reducing pain and improving function and quality of life in female patients with neck pain, thus emphasizing the need for thoracic treatment for such patients.

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

Based on the current findings, there is no additional treatment effect from adding spinal manipulative therapy to neck stretching exercises over 2 weeks for patients with persistent or recurrent neck pain.

Clinical Effectiveness and Efficacy of Chiropractic Spinal Manipulation for Spine Pain

Spine pain is a highly prevalent condition affecting over 11% of the world's population. It is the single leading cause of activity limitation and ranks fourth in years lost to disability globally, representing a significant personal, social, and economic burden. For the vast majority of patients with back and neck pain, a specific pathology cannot be identified as the cause for their pain, which is then labeled as non-specific. In a growing proportion of these cases, pain persists beyond 3 months and is referred to as chronic primary back or neck pain. To decrease the global burden of spine pain, current data suggest that a conservative approach may be preferable. One of the conservative management options available is spinal manipulative therapy (SMT), the main intervention used by chiropractors and other manual therapists. The aim of this narrative review is to highlight the most relevant and up-to-date evidence on the effectiveness (as it compares to other interventions in more pragmatic settings) and efficacy (as it compares to inactive controls under highly controlled conditions) of SMT for the management of neck pain and low back pain. Additionally, a perspective on the current recommendations on SMT for spine pain and the needs for future research will be provided. In summary, SMT may be as effective as other recommended therapies for the management of non-specific and chronic primary spine pain, including standard medical care or physical therapy. Currently, SMT is recommended in combination with exercise for neck pain as part of a multimodal approach. It may also be recommended as a frontline intervention for low back pain. Despite some remaining discrepancies, current clinical practice guidelines almost universally recommend the use of SMT for spine pain. Due to the low quality of evidence, the efficacy of SMT compared with a placebo or no treatment remains uncertain. Therefore, future research is needed to clarify the specific effects of SMT to further validate this intervention. In addition, factors that predict these effects remain to be determined to target patients who are more likely to obtain positive outcomes from SMT.

Immediate effect of a motor control exercise target to the neck muscles on upper cervical range of motion and motor control in patients with temporomandibular disorder

ObjectiveTo evaluate whether a single specific motor control training session for the neck flexor and deep extensor muscles improves upper cervical range of motion and neck motor control in patients with temporomandibular disorder (TMD) and compare them to a group without TMD. MethodsThis is a before and after, controlled study. The TMD group included women aged between 18-45 years old, complaining of pain in the orofacial region in the last 6 months and diagnosed with masticatory myofascial pain according to Research Diagnostic Criteria (RDC/MD). The control group included match-controls without TMD. The participants were evaluated to global and upper (Flexion Rotation Test - FRT) neck range of motion (ROM) and to neck motor control (Cranio-Cervical Flexion Test - CCFT). They were treated with a protocol of specific motor control exercises targeted to flexor and extensor neck muscles for 30 minutes. One day after the protocol the patients were reevaluated. ResultsA total of 23 volunteers were evaluated. The TMD group showed immediate improvement in left cervical rotation (p=0.043) and right FRT (p=0.036), while the control group did not show any improvement. There was no difference between the groups before and after treatment in relation to cervical movements. Regarding cervical motor control in both groups, the highest prevalence was of results between 24 and 26 mmHg after treatment, different from before the intervention (20 and 22 mmHg) in both groups.ConclusionA single session of specific neck motor control training only improved the left cervical rotation and upper right rotation in the TMD group, but not in the control group. There is no difference at the end of treatment between the groups. Volunteers with TMD showed improvement in the pattern of motor control of the neck when compared to volunteers without TMD.

Effects of Global Postural Reeducation versus Specific Therapeutic Neck Exercises on Pain, Disability, Postural Control, and Neuromuscular Efficiency in Women with Chronic Nonspecific Neck Pain: Study Protocol for a Randomized, Parallel, Clinical Trial

Background: Chronic nonspecific neck pain is the most frequent form of neck pain. It is more prevalent in women, and a costly public health issue. It is commonly associated with biomechanical, functional, proprioceptive, and postural impairments. The aim of this trial is to compare the effects of global postural exercises versus specific therapeutic exercises on neck pain, disability, mobility, pressure pain threshold, kinesiophobia, pain catastrophizing, postural control, and neuromuscular efficiency in women with chronic nonspecific neck pain. Methods and analysis: This study is a randomized, parallel-group and single blinded clinical trial. Sixty-two women with nonspecific chronic neck pain were recruited from the community of Guarda, Portugal, and randomly assigned to one of two intervention groups: (1) global postural reeducation (GPR group), (2) specific therapeutic exercises (STE group). The intervention was carried out over 4 weeks, with two sessions per week (eight sessions), and applied by a physiotherapist and paired with a daily individual at-home-exercise program. Primary outcomes are neck pain intensity and disability (Numerical Pain Rating Scale, Neck Disability Index). Secondary outcomes are cervical mobility and pressure pain threshold (CROM, algometry), attitude to pain (kinesiophobia, pain catastrophizing), standing postural control (Center of Pressure (COP) displacements), and neuromuscular efficiency (electromyography). There are four points of evaluation where the outcomes were assessed twice before the intervention, 1 week apart, and the two post-intervention assessments will be carried out after four and eight sessions. The objective was to increase scientific knowledge of different exercise modalities, such as global postural reeducation, in musculoskeletal disorders.

Focus on the Scapular Region in the Rehabilitation of Chronic Neck Pain Is Effective in Improving the Symptoms: A Randomized Controlled Trial

Chronic neck pain is a common human health problem. Changes in scapular posture and alteration of muscle activation patterns of scapulothoracic muscles are cited as potential risk factors for neck pain. The purpose of this study was to compare the effects of neck exercise training (NET) with and without scapular stabilization training (SST) on pain intensity, the scapula downward rotation index (SDRI), forward head angle (FHA) and neck range of motion (ROM) in patients with chronic neck pain and scapular dyskinesia. A total of sixty-six subjects with chronic neck pain and scapular dyskinesia were randomly divided into three groups: neck exercise training, n = 24, combined training (NET + SST), n = 24 and a control group, n = 24. Pain intensity, SDRI, FHA and ROM were measured by the numerical rating scale, caliper, photogrammetry and IMU sensor, respectively. When the combined intervention group consisting of NET and SST was compared with NET alone at six weeks, there was a statistically significant difference in pain intensity, SDRI, FHA and cervical ROM for flexion and extension (p ≤ 0.05). Adding scapular exercises to neck exercises had a more significant effect in decreasing pain intensity, SDRI, FHA and increased cervical ROM than neck exercises alone in patients with chronic neck pain. These findings indicate that focus on the scapular posture in the rehabilitation of chronic neck pain effectively improves the symptoms.
