Daoyin therapy in chronic neck pain: study protocol for a randomized controlled trial.

BACKGROUND: Daoyin therapy (DT), an ancient therapeutic approach with a history spanning thousands of years, has traditionally been employed to address musculoskeletal pain and psychosomatic disorders. However, the application of DT for chronic neck pain (CNP) has received limited attention in the existing literature, and systematic randomized clinical trials (RCTs) in this context remain scarce. This manuscript outlines an RCT protocol designed to investigate whether DT is more effective at alleviating CNP in adult individuals compared to other interventions. METHODS: A 12-week RCT was conducted, with participants undergoing randomization into one of three groups: DT, Meditation + Fitness Exercise (M+FE), or a control group. Participants in the DT and M + FE groups attended their respective training classes three times per week for 12 weeks. Participants in the control group were required to attend health education workshops every 2 weeks. Following the 12-week intervention period, all participants underwent follow-up assessments at the 16th week. Outcome measures encompassed the Simplified Chinese Neck Pain and Disability Scale (SC-NPAD) and Visual Analog Scale (VAS) for pain assessment, Static Neck Posture Assessment (SNPA) to evaluate neck and shoulder posture and function, Short Form-36 (SF-36) to assess quality of life, and blood tests measuring 5-Hydroxytryptamine (5-HT), Norepinephrine/Noradrenaline (NE/NA), γ-aminobutyric acid (GABA), Adreno-Cortico-Tropic-Hormone (ACTH), ß-Endorphin (ß-EP), and Calcitonin-Gene-Related Peptide (CGRP) levels via high-performance liquid chromatography (HPLC), chemiluminescence immunoassay (CLIA), enzyme-linked immunosorbent assay (ELISA), and radioimmunoassay (RIA). Brain activity changes were monitored through MRI scans. Repeated measures analyses of variance (ANOVAs) will be used to evaluate the outcomes at baseline, at the 12th week, and at the 16th week. Generalized Estimating Equation (GEE) models will be applied to analyze changes in outcomes over time and differences between groups. DISCUSSION: This trial aims to evaluate the efficacy of DT in comparison to other interventions and explore the neuroendocrine mechanisms underlying its effects in adults with CNP. If the intervention and procedures demonstrate feasibility and acceptability, there are plans to conduct a more extensive controlled trial. This could potentially pave the way for the broader application of DT, not only in the context of CNP but also for other chronic diseases. TRIAL REGISTRATION: This trial has been registered with the Chinese Clinical Trial Registry (Registration ID: [ChiCTR2400079571]).

Massage for neck pain.

BACKGROUND: Massage is widely used for neck pain, but its effectiveness remains unclear. OBJECTIVES: To assess the benefits and harms of massage compared to placebo or sham, no treatment or exercise as an adjuvant to the same co-intervention for acute to chronic persisting neck pain in adults with or without radiculopathy, including whiplash-associated disorders and cervicogenic headache. SEARCH METHODS: We searched multiple databases (CENTRAL, MEDLINE, EMBASE, CINAHL, Index to Chiropractic Literature, trial registries) to 1 October 2023. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing any type of massage with sham or placebo, no treatment or wait-list, or massage as an adjuvant treatment, in adults with acute, subacute or chronic neck pain. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. We transformed outcomes to standardise the direction of the effect (a smaller score is better). We used a partially contextualised approach relative to identified thresholds to report the effect size as slight-small, moderate or large-substantive. MAIN RESULTS: We included 33 studies (1994 participants analysed). Selection (82%) and detection bias (94%) were common; multiple trials had unclear allocation concealment, utilised a placebo that may not be credible and did not test whether blinding to the placebo was effective. Massage was compared with placebo (n = 10) or no treatment (n = 8), or assessed as an adjuvant to the same co-treatment (n = 15). The trials studied adults aged 18 to 70 years, 70% female, with mean pain severity of 51.8 (standard deviation (SD) 14.1) on a visual analogue scale (0 to 100). Neck pain was subacute-chronic and classified as non-specific neck pain (85%, including n = 1 whiplash), radiculopathy (6%) or cervicogenic headache (9%). Trials were conducted in outpatient settings in Asia (n = 11), America (n = 5), Africa (n = 1), Europe (n = 12) and the Middle East (n = 4). Trials received research funding (15%) from research institutes. We report the main results for the comparison of massage versus placebo. Low-certainty evidence indicates that massage probably results in little to no difference in pain, function-disability and health-related quality of life when compared against a placebo for subacute-chronic neck pain at up to 12 weeks follow-up. It may slightly improve participant-reported treatment success. Subgroup analysis by dose showed a clinically important difference favouring a high dose (≥ 8 sessions over four weeks for ≥ 30 minutes duration). There is very low-certainty evidence for total adverse events. Data on patient satisfaction and serious adverse events were not available. Pain was a mean of 20.55 points with placebo and improved by 3.43 points with massage (95% confidence interval (CI) 8.16 better to 1.29 worse) on a 0 to 100 scale, where a lower score indicates less pain (8 studies, 403 participants; I2 = 39%). We downgraded the evidence to low-certainty due to indirectness; most trials in the placebo comparison used suboptimal massage doses (only single sessions). Selection, performance and detection bias were evident as multiple trials had unclear allocation concealment, utilised a placebo that may not be credible and did not test whether blinding was effective, respectively. Function-disability was a mean of 30.90 points with placebo and improved by 9.69 points with massage (95% CI 17.57 better to 1.81 better) on the Neck Disability Index 0 to 100, where a lower score indicates better function (2 studies, 68 participants; I2 = 0%). We downgraded the evidence to low-certainty due to imprecision (the wide CI represents slight to moderate benefit that does not rule in or rule out a clinically important change) and risk of selection, performance and detection biases. Participant-reported treatment success was a mean of 3.1 points with placebo and improved by 0.80 points with massage (95% CI 1.39 better to 0.21 better) on a Global Improvement 1 to 7 scale, where a lower score indicates very much improved (1 study, 54 participants). We downgraded the evidence to low-certainty due to imprecision (single study with a wide CI that does not rule in or rule out a clinically important change) and risk of performance as well as detection bias. Health-related quality of life was a mean of 43.2 points with placebo and improved by 5.30 points with massage (95% CI 8.24 better to 2.36 better) on the SF-12 (physical) 0 to 100 scale, where 0 indicates the lowest level of health (1 study, 54 participants). We downgraded the evidence once for imprecision (a single small study) and risk of performance and detection bias. We are uncertain whether massage results in increased total adverse events, such as treatment soreness, sweating or low blood pressure (RR 0.99, 95% CI 0.08 to 11.55; 2 studies, 175 participants; I2 = 77%). We downgraded the evidence to very low-certainty due to unexplained inconsistency, risk of performance and detection bias, and imprecision (the CI was extremely wide and the total number of events was very small, i.e < 200 events). AUTHORS' CONCLUSIONS: The contribution of massage to the management of neck pain remains uncertain given the predominance of low-certainty evidence in this field. For subacute and chronic neck pain (closest to 12 weeks follow-up), massage may result in a little or no difference in improving pain, function-disability, health-related quality of life and participant-reported treatment success when compared to a placebo. Inadequate reporting on adverse events precluded analysis. Focused planning for larger, adequately dosed, well-designed trials is needed.

Changes in Multiple Aspects of Pain Outcomes After Rehabilitation: Analysis of Pain Data in a Randomized Controlled Trial Evaluating the Effects of Adding Sensorimotor Training to Manual Therapy and Exercise for Chronic Neck Pain.

OBJECTIVES: To examine changes in pain outcomes to fully evaluate the effect of adding sensorimotor training to manual therapy and exercise in patients with chronic neck pain and sensorimotor deficits. Concordance was examined between pain distribution and pain intensity and patient-reported outcomes. METHODS: Participants (n=152) were randomly allocated into 4 intervention groups: One group received local neck treatment (NT) comprising manual therapy and exercise and the other 3 groups received additional sensorimotor training (either joint position sense/oculomotor exercises, balance exercises or both). Treatment was delivered twice a week for 6 weeks. Pain and patient-reported outcomes were measured at baseline, posttreatment, and 3-, 6- and 12-month follow-ups. RESULTS: There were greater changes in pain location, extent, and intensity at 6- and 12-month follow-ups in the sensorimotor training groups compared with the NT group ( P <0.05). A greater number of patients in the sensorimotor training groups gained ≥50% reduction in pain extent and intensity relative to the NT group at 6 and 12 months ( P <0.05). Clinical improvement in pain extent was concordant with pain intensity (adjusted kappa=056 to 0.66, %agreement=78.3 to 82.9, P <0.001) and disability (adjusted kappa=0.47 to 0.58, % agreement=73.7 to 79.0, P <0.01) at 3-, 6- and 12-month follow-ups, but not with function and well-being. The concordance tended to decline with time. DISCUSSION: Multiple aspects of the pain experience improved in the longer term by adding sensorimotor training to NT for patients with neck pain and sensorimotor deficits. The concordance between pain and patient-reported outcomes was not always evident and varied over time, suggesting the need for multidimensional assessments of pain.

Is adding dry needling to a standard care protocol beneficial in patients with chronic neck pain? A randomized placebo-controlled trial.

PURPOSE: To evaluate the short-term effects of adding a dry needling therapy to a standard care protocol based on education, exercise and electrotherapy, compared to a sham procedure and to a standard care protocol in isolation in patients with chronic neck pain. MATERIAL AND METHODS: A randomized placebo-controlled trial was performed. The participants in the dry needling group received a standard care protocol based on patient education, therapeutic exercise and electrotherapy, as well as two sessions of dry needling in the upper trapezius, levator scapulae, and/or sternocleidomastoid muscles. The participants in the sham dry needling group received the same standard care protocol and two sessions of sham dry needling. The participants in the control group received the same standard care protocol. The outcomes measured were pain intensity, pressure pain threshold, neck disability, range of movement, activation of deep cervical flexor muscles, kinesiophobia, pain catastrophizing, anxiety, and depression. RESULTS: No significant group by time interactions were found for any of the outcome variables except for lower cervical spine range of movement (F = 3.79; p = 0.030). CONCLUSION: The addition of two sessions of dry needling in the superficial neck muscles to a standard protocol did not yield superior results compared to either the standard care alone or the standard care plus sham dry needling in patients with chronic neck pain in any outcome except for cervical range of movement.

Effectiveness of musculoskeletal manipulations in patients with neck pain: a protocol for a systematic review and network meta-analysis.

INTRODUCTION: Neck pain is a common problem that severely affects physical and mental health. While musculoskeletal manipulations are recommended as the first-line treatment for adults with neck pain, the comparative effectiveness of different musculoskeletal manipulations remains unclear. This systematic review and network meta-analysis of randomised controlled trials (RCTs) will compare the effectiveness of different types of musculoskeletal manipulations, with the overarching aim of guiding clinical practice. METHODS AND ANALYSIS: Two independent reviewers will search four English electronic databases (Web of Science, Cochrane Library, EMBASE, PubMed) and three Chinese electronic databases (China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang) for relevant RCTs published from 1 January 2013 to 30 April 2023. The Clinical Trials Registry (ClinicalTrials.gov) will be searched for completed but unpublished RCTs. English and Chinese will be used to search English databases and Chinese databases, respectively. RCTs of musculoskeletal manipulations for adults (aged ≥18 years) with neck pain will be considered eligible for inclusion. A pairwise meta-analysis and network meta-analysis will be performed, and pooled risk ratios, standardised mean differences and 95% CIs will be determined. ETHICS AND DISSEMINATION: Ethics approval is not required as this study is a literature review. The results of this review will be published in peer-reviewed journals or disseminated at conferences.

Clinical effectiveness of trigger point acupuncture on chronic neck and shoulder pain (katakori) with work productivity loss in office workers: a randomized clinical trial.

OBJECTIVES: To evaluate whether trigger point acupuncture (TrPA) is beneficial for office workers who have reduced job performance (presenteeism) due to chronic neck and shoulder pain (katakori). METHODS: A 4-week single-center randomized controlled trial was conducted on 20 eligible female office workers with chronic neck and shoulder pain of at least 3-month duration. The control group implemented only workplace-recommended presenteeism measures, whereas the intervention group received TrPA up to 4 times per month in addition to the presenteeism measures recommended by each workplace. The major outcome measure was the relative presenteeism score on the World Health Organization Health and Work Performance (WHO-HPQ). The secondary outcome measures were pain intensity (numerical rating scale), absolute presenteeism (WHO-HPQ), anxiety and depression (Hospital Anxiety and Depression Scale; HADS), catastrophic thoughts related to pain (Pain Catastrophizing Scale; PCS), and sleep (Athens Insomnia Scale; AIS). RESULTS: All 9 cases in the intervention group and 11 cases in the control group were analyzed. TrPA up to 4 times per month reduced the intensity of neck and shoulder pain by 20% (P < .01, d = 1.65) and improved labor productivity (relative presenteeism value) by 0.25 (P < .01, d = 1.33) compared with the control group over 1 month. No significant differences were observed between the 2 groups in terms of absolute presenteeism score, HADS, PCS, or AIS. CONCLUSIONS: These results suggest that regular intervention with TrPA may be effective in the relative presenteeism score before and after the intervention and the degree of neck and shoulder pain over 28 days compared with the control group.

Dry Needling Versus Manual Therapy for Patients With Mechanical Neck Pain: A Randomized Controlled Trial.

OBJECTIVE: To compare the short- and intermediate-term effects of dry needling to manual therapy on pain, disability, function, and patient-perceived improvement in patients with mechanical neck pain. DESIGN: A single (therapist) blinded randomized controlled trial. METHODS: Seventy-eight patients (mean ± SD age, 50.74 ± 13.81) were randomly assigned to one of the 2 groups: (1) dry needling and therapeutic exercises (DN + Exercises) and (2) manual therapy and therapeutic exercises (MT + Exercises). Both groups received 7 treatment sessions over a maximum of 6 weeks. Outcome measures, collected at baseline, 2 weeks, discharge (7th treatment session), and 3 months after discharge, were as follows: Neck Disability Index (NDI), numeric pain-rating scale (NPRS), Patient-Specific Functional Scale (PSFS), global rating of change (GROC), Fear-Avoidance Belief Questionnaire (FABQ), and Deep Neck Flexor Endurance Test (DNFET). Data were analyzed with mixed-model analysis of covariance (ANCOVA), using pretest scores as covariates, and a Mann-Whitney U test for GROC scores. RESULTS: The ANCOVA revealed significant group-by-time interaction for all variables. Significant between-group differences, favoring MT + Exercises, were observed at all 3 time points on the NDI (2 weeks: F1,446 = 172.68, P≤.001, [Formula: see text] = .27; discharge: F1,446 = 254.15, P≤.001, [Formula: see text] = .36; and 3 months: F1,446 = 339.40, P≤.001, [Formula: see text] = .43). Results for the MT + Exercises group exceeded recommended minimal clinically important difference for all variables, at all follow-up points. CONCLUSION: MT + Exercises was more effective, both in the short term and intermediate term, than DN + Exercises in reducing pain, disability, and improving function in patients with mechanical neck pain.

Efficacy of acupuncture for whiplash injury: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to establish clinical evidence for acupuncture by analysing data from trials that demonstrated the efficacy of acupuncture for whiplash-associated disorder (WAD) with the following research question: Is acupuncture treatment effective for symptom alleviation in patients with WAD compared with other usual care? DESIGN: A systematic review and meta-analysis. DATA SOURCES: PubMed, Ovid Medline, Embase, The Cochrane Library, China National Knowledge Infrastructure, ScienceOn, KMBASE, Korean Studies Information Service System, Korea Med, Oriental Medicine Advanced Searching Integrated System and Research Information Sharing Service were searched from their inception to 1 October 2023. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCTs) using acupuncture on patients with WAD. The outcomes were the pain visual analogue scale (VAS) score or numerical rating scale score for neck pain, the range of motion (ROM) of the neck, the Neck Disability Index and safety. DATA EXTRACTION AND SYNTHESIS: Two independent researchers analysed and extracted data from the selected literatures. The risk of bias and the quality of evidence were assessed according to the Cochrane Handbook for Systematic Reviews of Interventions and the Grading of Recommendations Assessment, Development, and Evaluation method, respectively. RESULTS: A total of 525 patients with WAD from eight RCTs were included in this study. The meta-analysis revealed that the outcomes showed significant differences in the pain VAS score (standard mean difference (SMD): -0.57 (-0.86 to -0.28), p<0.001) and ROM-extension (SMD: 0.47 (0.05 to 0.89), p=0.03). The risk of bias assessment revealed that four studies published after 2012 (50%, 4 out of 8 studies) showed low bias in most domains. The pain VAS score was graded as having moderate certainty. CONCLUSION: Acupuncture may have clinical value in pain reduction and increasing the ROM for patients with WAD. High-quality RCTs must be conducted to confirm the efficacy of acupuncture in patients with WAD. TRIAL REGISTRATION NUMBER: PROSPERO CRD42021261595.

Modulatory effects of acupuncture on raphe nucleus-related brain circuits in patients with chronic neck pain: A randomized neuroimaging trial.

OBJECTIVE: Acupuncture has shown promise in treating neck pain. Clinical trials have shown mixed results, possibly due to heterogeneous methodologies and the lack of knowledge regarding underlying brain circuit mechanism of action. In this study, we investigated the specific contribution of the serotonergic system in treating neck pain, and the specific brain circuits involved. METHODS: A total of 99 patients with chronic neck pain (CNP) were randomized to receive true acupuncture (TA) or sham acupuncture (SA) 3 times weekly for 4 weeks. Patients with CNP in each group were assessed for primary outcomes by measuring the Visual Analog Scale (VAS) and the duration of each attack; secondary outcomes were measured using the Neck Disability Index (NDI), Northwick Park Neck Pain Questionnaire (NPQ), McGill Pain Questionnaire (MPQ), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and the 12-item Short Form Quality Life Scale (SF-12); levels of functional circuits connectivity were assessed using resting-state functional magnetic resonance imaging in the dorsal (DR) and median (MR) raphe nucleus, before and after undergoing acupuncture. RESULTS: Patients receiving TA showed more extensive symptom improvement compared with SA. Regarding the primary outcomes, changes observed in the TA group were as follows: VAS = 16.9 mm (p < 0.001) and the duration of each attack = 4.30 h (p < 0.001); changes in the SA group: VAS = 5.41 mm (p = 0.138) and the duration of each attack = 2.06 h (p = 0.058). Regarding the secondary outcomes, changes in the TA group: NDI = 7.99 (p < 0.001), NPQ = 10.82 (p < 0.001), MPQ = 4.23 (p < 0.001), SAS = 5.82 (p < 0.001), SDS = 3.67 (p = 0.003), and SF-12 = 3.04 (p < 0.001); changes in the SA group: NDI = 2.97 (p = 0.138), NPQ = 5.24 (p = 0.035) and MPQ = 2.90 (p = 0.039), SAS = 1.48 (p = 0.433), SDS = 2.39 (p = 0.244), and SF-12 = 2.19 (p = 0.038). The modulatory effect of TA exhibited increased functional connectivity (FC) between the DR and thalamus, between the MR and parahippocampal gyrus, amygdala, and insula, with decreased FC between the DR and lingual gyrus and middle frontal gyrus, between the MR and middle frontal gyrus. Furthermore, changes in the DR-related circuit were specifically associated with the intensity and duration of pain, and the MR-related circuit was correlated with the quality of life with CNP. CONCLUSION: These results demonstrated the effectiveness of TA in treating neck pain and suggested that it regulates CNP by reconfiguring the function of the raphe nucleus-related serotonergic system.

Effects of muscle specific as compared to movement specific muscle energy technique in mechanical neck pain: A randomized controlled trial.

BACKGROUND: Muscle energy technique (MET) is found to be effective for the management of neck pain and in addition to the muscle specific approach, clinicians may also adopt movement specific approach for METs. However, the literature is deficient in terms of comparison of muscle specific and movement specific METs in the management of mechanical neck pain. OBJECTIVE: To compare the effects of muscle specific and movement specific METs in the management of mechanical neck pain. METHODS: A single blind parallel design randomized controlled trial was conducted on 66 participants with mechanical neck pain ranging from 40-80 mm on visual analogue scale (VAS), aged between 19-44 years with pain and limitation on cervical motion. Once included, the participants were randomly allocated to two groups, namely the muscle specific MET group and the movement specific MET group. Outcome measures included VAS, Neck Disability Index (NDI) and cervical range of motion (ROM). RESULTS: No significant differences (p> 0.05) were observed, neither immediately nor after 5 days, between muscle specific and movement specific MET in terms of VAS, NDI and ROM. However, a significant difference (p< 0.05) was observed in both groups in terms of pre- and post-analysis for all outcome variables. CONCLUSIONS: Both muscle specific and movement specific METs are effective in the management of mechanical neck pain, with no significant differences between the two treatment techniques.

Does manual therapy meaningfully change quantitative sensory testing and patient reported outcome measures in patients with musculoskeletal impairments related to the spine?: A 'trustworthy' systematic review and meta-analysis.

OBJECTIVES: To perform a 'trustworthy' systematic review (SR) with meta-analysis on the potential mechanisms of manual therapy used to treat spinal impairments. DESIGN: SR with meta-analysis. LITERATURE SEARCH: Articles published between January 2010 and October 2022 from CENTRAL, CINAHL, MEDLINE, PubMed, ProQuest, and PEDro. METHODS: This SR included English-language randomized clinical trials (RCTs) involving manual therapy to treat spinal impairments in adults. The primary outcome was pressure pain thresholds (PPTs). To synthesize RCTs with high confidence in estimated effects using the GRADE, RCTs with questionable prospective, external, and internal validity, and high risk of bias (RoB) were excluded. RESULTS: Following title and abstract screening, 89 full-text RCTs were reviewed. Twenty-two studies included the criteria of interest. Sixteen were not prospectively registered, two contained discussion/conclusions judged to be inconsistent with the registry, and one was rated as having a high RoB. Three studies met the inclusion criteria; heterogeneous interventions and locations for PPT testing prevented synthesis into practice recommendations. The two studies with high confidence in estimated effects had small effect sizes, and one study had confidence intervals that crossed zero for the outcome measures of interest. DISCUSSION: Standardized PPT testing, as a potential measure of centrally mediated pain, could provide clues regarding the mechanisms of manual therapy or help identify/refine research questions. CONCLUSION: High-quality RCTs could not be synthesized into strong conclusions secondary to the dissimilarity in research designs. Future research regarding quantitative sensory testing should develop RCTs with high confidence in estimated effects that can be translated into strong recommendations.

Description of massage interventions in randomised clinical trials for neck pain; a review using the TIDieR checklist.

OBJECTIVE: How interventions are reported can impact the ability to implement these intervention in clinical practice. Therefore, our aim is to assess the reporting of massage interventions in randomised controlled trials for patients with neck pain. DATA SOURCES: This manuscript concerns a secondary analysis of trials evaluating massage for neck pain selected for a scoping review. An updated literature search was completed using four databases to 31 July 2023. REVIEW METHODS: Trials were selected that evaluate massage interventions. Two independent assessors extracted descriptive information, methodological quality (PEDro-scale) and assessed completeness of reporting of the intervention using the Template for Intervention Description and Replication (TIDier-checklist). We present frequencies of the extracted data. RESULTS: We included 35 trials (2840 patients) with neck pain. Most trials (n = 23) included patients with chronic non-specific neck pain. We found a wide variety of massage interventions from Chinese massage, Swedish massage to myofascial release. In addition, the dose, number of sessions and the duration of the intervention varied widely. The methodological quality overall was fair to good (varied between 4-8/10), and we found a moderate completeness of reporting. All trials provided the name of the intervention, 30 (86%) provided a rationale and 26 (74%) trials described details of the massage intervention. CONCLUSION: The massage interventions were moderately described in trials in patients with neck pain, but provided enough information to guide the decision making for designing future Network Meta-analysis as to what trials need to be considered when grouping massage interventions in a clinically relevant way.

Effect of osteopathic manipulative treatment and Bio-Electro-Magnetic Energy Regulation (BEMER) therapy on generalized musculoskeletal neck pain in adults.

CONTEXT: General neck pain is a prevalent complaint made by patients to their physicians and is often of a suspected musculoskeletal origin. Osteopathic manipulative treatment (OMT) is a form of manual therapy utilized by osteopathic physicians and some allopathic physicians to treat a broad variety of musculoskeletal ailments, including neck pain. Bio-Electro-Magnetic Energy Regulation (BEMER) is an emerging therapeutic modality that deploys a biorhythmically defined stimulus through a pulsed electromagnetic field and has been shown to reduce musculoskeletal pain. Studies on these treatments have independently yielded promising results. Therefore, it is possible that the utility of OMT and BEMER can produce an additive improvement in the treatment of neck pain. OBJECTIVES: The objectives of this study are to investigate the individual and combined effects of OMT and BEMER therapy on neck pain in adults. METHODS: Adults with nonspecific neck pain were recruited for the study. A total of 44 participants met the study inclusion criteria and were randomized into one of four study groups: OMT-only, BEMER-only, OMT+BEMER, or CONTROL (light touch and sham). Forty subjects completed the study, and data for 38 participants were included in our analyses. An OMT and BEMER protocol were specifically designed for this study under the guidance of a licensed osteopathic physician. Participants underwent intervention for a duration of 3 weeks. Data were obtained through baseline and postintervention assessments utilizing three surveys: Neck Disability Index (NDI), Visual Analog Scale (VAS), and Short Form 12-item Health Survey (SF-12, divided into Mental and Physical). One-way analysis of variance (ANOVA) analysis was performed retrospectively on pre- and postintervention absolute means between study groups. Significance was set at p<0.05. RESULTS: One-way ANOVA analysis demonstrated a statistically significant difference in pre- vs. postintervention mean scores between BEMER and CONTROL (p<0.05), BEMER compared to OMT (p<0.005), and BEMER compared to BEMER+OMT (p<0.05), in the NDI. The OMT+BEMER group reported an average reduction in pain on the VAS of 21.3 (±29.3) points, or a 65.0 % reduction of pain. A similarly substantial decrease in pain was reported in the BEMER study group, which showed a 46.2 % reduction in pain from baseline. The OMT and CONTROL study groups only reported a 2.9 and 23.9 % decrease, respectively. The BEMER and OMT+BEMER study groups also demonstrated a reduction in subjective reporting on the NDI, by 53.8 and 26.3 %, respectively. The BEMER study group also achieved the most substantial improvement in mental and physical well-being as reported by the SF-12. CONCLUSIONS: Study arms that incorporated BEMER yielded improvements on the NDI, VAS, and SF-12, indicating benefits to BEMER regarding improved overall functionality in routine daily activities as well as a reduction in nonspecific neck pain. Perceived pain, as demonstrated on the VAS, was seemingly improved in an additive fashion from the BEMER group to the OMT+BEMER group, although the results did not achieve statistical significance. Further study with greater participation could provide additional insight.

Specific and shared mechanisms associated with treatment for chronic neck pain: study protocol for the SS-MECH trial.

BACKGROUND: Treatment mechanisms involve the steps or processes through which an intervention unfolds and produces change in an outcome variable. Treatment mechanisms can be specific to the intervention provided (i.e. pain modulation) or shared with other treatments (i.e. reduced fear of movement). Whether specific and shared treatment mechanisms are different across interventions and whether they lead to the outcomes seen in trials is largely unknown. The management of individuals with chronic neck pain routinely include manual therapy (MT) and resistance exercise (RE), as both approaches are included in clinical practice guidelines and both yield similar outcomes. OBJECTIVES: Our study plans to answer two research questions: 1) what are the specific mechanisms associated with MT versus interventions (and are these different), and 2) what are the shared mechanisms associated with these interventions, and do specific or shared mechanisms mediate clinical outcomes? METHODS: This study will involve a 2-group parallel (1:1) single-blinded randomized trial to compare the specific and potential shared treatment mechanisms between these two approaches. We will enroll individuals with a history of chronic neck pain and evaluate whether specific or shared mechanisms mediate clinical outcomes. RESULTS: We hypothesize that MT and RE approaches will both exhibit different specific treatment mechanisms, and that both approaches will exhibit shared treatment mechanisms, which will notably influence outcomes at both discharge and 6-months. CONCLUSIONS: This study is important because it will help identify what specific or shared treatment mechanisms are associated with different interventions and, how different treatment mechanisms influence clinical outcomes.

Self-stretching exercises with kinesio taping for management of chronic nonspecific neck pain in taxi drivers: A single-blind, randomized controlled trial.

OBJECTIVES: Taxi drivers experience chronic neck pain owing to their posture while driving. The aim of this study was to investigate the effect of self-stretching exercises with kinesio taping on pain, stress, pressure pain threshold (PPT), disability, cervical range of motion (CROM) in this population. DESIGN: A single-blind, randomized controlled trial SETTING: Forty-three taxi drivers with nonspecific chronic nonspecific neck pain were randomly assigned to experimental (n = 22) and control (n = 21) groups. METHODS: In the experimental group, self-stretching exercises were performed 3 times a day, 5 days per week, for 4 weeks, with kinesio taping applied while driving. In the control group, only kinesio taping was applied while driving for 4 weeks. Pain intensity, stress intensity, PPT, neck disability, and CROM were assessed pre-intervention, post-intervention, and at 4 weeks post-intervention. RESULTS: Significant time and group interactions were observed in pain intensity at rest (p = 0.048) and while driving (p = 0.001). In the experimental group, the Pre - Post - Follow-up mean (95% CI) was 4.41 (4.14 to 4.68) - 3.82 (3.57 to 4.07) - 3.78 (3.55 to 3.99). In the control group, the Pre - Post - Follow-up mean (95% CI) was 4.29 (4.01 to 4.56) - 3.86 (3.60 to 4.11) - 4.05 (3.82 to 4.27) for pain at rest. In the experimental group, the Pre - Post - Follow-up mean (95% CI) was 4.91 (4.63 to 5.19) - 4.00 (3.76 to 4.24) - 3.69 (3.69 to 4.22), while in the control group, the Pre - Post - Follow-up mean (95% CI) was 4.81 (4.53 to 5.09) - 4.38 (4.13 to 4.63) - 4.57 (4.30 to 4.85) for pain while driving. PPT on the right (p = 0.029) and left (p < 0.001) sides, and neck disability (p = 0.001) also showed significant time and group interactions. NDI was not clinically significant based on the minimum clinically important difference. All CROM showed significant time and group interactions (flexion, p = 0.008; right lateral flexion, p = 0.009; left lateral flexion, p = 0.004; right rotation, p = 0.001; left rotation, p = 0.001), except for extension. CONCLUSION: This study showed that self-stretching exercises with kinesio taping provided benefits over kinesio taping alone on pain intensity, PPT, disability, and CROM in taxi drivers with nonspecific chronic neck pain. CLINICAL TRIAL REGISTRATION: This study registered with the Clinical Research Information Service (WHO International Clinical Trials Registry Platform) on September 22, 2020 (KCT0005406).

Chiropractic spinal manipulative therapy for acute neck pain: A 4-arm clinical placebo randomized controlled trial. A prospective study protocol.

INTRODUCTION: Neck pain poses enormous individual and societal costs worldwide. Spinal manipulative therapy and Non-Steroidal Anti-Inflammatory Drug treatment are frequently used despite a lack of compelling efficacy data. This protocol describes a multicentre 4-arm, clinical placebo randomized controlled trial (RCT), investigating the efficacy of chiropractic spinal manipulative therapy (CSMT) versus sham CSMT, ibuprofen, and placebo medicine for acute neck pain. This superiority study will employ parallel groups, featuring a 1:1:1:1 allocation ratio. MATERIAL AND METHODS: We will randomize 320 participants equally into four groups: CSMT, sham CSMT, ibuprofen, or placebo medicine. CSMT groups are single-blinded, while the medicine groups are double-blinded. Data will be collected at baseline (Day 0), during treatment and post-treatment. The primary endpoint will assess the difference in mean pain intensity from Day 0 to Day 14 on a numeric rating scale 0-10; the CSMT group is compared to sham CSMT, ibuprofen, and placebo medicine groups, respectively. Secondary endpoints will assess mean pain intensity and mean duration at different time points, and adverse events, blinding success, and treatment satisfaction, including comparison between ibuprofen and placebo medicine. Power calculation is based on a mean neck pain rating of 5 at Day 0, with standard deviation of 1 in all groups. Mean pain reduction at Day 14 is expected to be 60% in the CSMT group, 40% in sham CSMT and ibuprofen groups, and 20% in the placebo medicine group. A linear mixed model will compare the mean values for groups with corresponding 95% confidence intervals. P values below 0.017 will be considered statistically significant. All analyses will be conducted blinded from group allocation. DISCUSSION: This RCT aims towards the highest research standards possible for manual-therapy RCTs owing to its two placebo arms. If CSMT and/or ibuprofen proves to be effective, it will provide evidence-based support for CSMT and/or ibuprofen for acute neck pain. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05374057.

Acupuncture for Japanese Katakori (Chronic Neck Pain): A Randomized Placebo-Controlled Double-Blind Study.

Background and Objectives: Although acupuncture is listed as a beneficial treatment for neck/shoulder stiffness, which has increased with the spread of information technology, to date, evidence of its efficacy under double-blind conditions has not been shown. This study aimed to assess whether acupuncture treatment with superficial skin piercing is superior to placebo treatment. Materials and Methods: A randomized, double-blind (practitioner-patient) placebo-controlled trial was performed at a single center with four arms (ISRCTN76896018). Four hundred patients with essential neck/shoulder stiffness were randomly assigned to penetrating needle treatment (acupuncture ritual and skin penetration), skin-touch needle treatment (acupuncture ritual and skin touch), no-touch needle treatment (acupuncture ritual alone), and no-treatment control. Each of the six acupuncturists applied a needle to each of the four acupoints in the neck/shoulder of 50 patients. Results: Each of the three treatments significantly (p = 0.01) improved neck/shoulder stiffness compared with the no-treatment control immediately and 24 h after treatment. There was a significant improvement in penetrating needle treatment over no-touch needle treatment 24 h later. However, there was no significant difference between the penetrating and skin-touch and skin-touch vs. no-touch. Conclusions: All treatments that received the ritual of acupuncture were better than the no-treatment control. Only genuine acupuncture involves the specific effects of needle insertion into the body. The acupuncture ritual had a significant impact on the subjective improvement of neck/shoulder stiffness; however, improvement with ritual alone versions of placebo acupuncture was not maintained as with superficial skin piercing. Our study provides important evidence of acupuncture efficacy and information regarding inert no-touch placebo control in acupuncture research.

Problems With Medium-Sized Joints: Neck Conditions.

The incidence of neck pain in US primary care settings ranges from 10% to 21% per year. A key component in evaluation of patients with neck pain is identification of red flag signs or symptoms that indicate the need for urgent evaluation for possible serious conditions. These include fever, unexplained weight loss, trauma, vision changes, new or severe headache, and altered mental status, among others. Patients with acute onset or worsening chronic neck pain without trauma or red flag signs or symptoms should be assessed initially with x-ray. Magnetic resonance imaging study is recommended for patients with progressive neurologic symptoms, neurologic compromise, suspected infection, or other red flag signs or symptoms. Common conditions and injuries associated with neck pain in the primary care setting include cervical strains and sprains, cervical spondylosis, cervical discogenic pain, cervical radiculopathy and myelopathy, whiplash, cervical fracture, and postural pain. Most patients with neck pain without red flag signs or symptoms recover with conservative management, however, there is little evidence to support these treatments. Pharmacotherapy includes nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants. Small benefits have been shown for combination exercise programs, mind-body programs, and acupuncture. Referral for surgical management is indicated for patients with progressive neurologic deficits.
