Upper cervical and upper thoracic manipulation versus mobilization and exercise in patients with cervicogenic headache: a multi-center randomized clinical trial

The majority of clinical trials assessing mobilization and manipulation for neck pain lack a pragmatic approach: a systematic review of 174 trials

BACKGROUND

Disorders of the cervical spine are some of the costliest musculoskeletal conditions to manage globally. Joint mobilization and manipulation have been shown to be an effective treatment for neck pain. However, the generalizability and clinical translation depends on the nature of the trial designs that inform its use. The extent to which randomized control trials (RCTs) assessing manual therapy treatments for cervical spine disorders fall on the efficacy (explanatory) -effectiveness (pragmatic) spectrum often informs how the findings are translated into clinical practice.

OBJECTIVE

The aim of this systematic review was to determine where RCTs of manual therapy for neck disorders fall on the efficacy-effectiveness spectrum.

METHODS

A search of three electronic databases including PubMed, CINAHL, and CENTRAL were completed for trials published from inception to May 2023. RCTs in which joint mobilization or manipulation were used to treat cervical spine disorders were assessed on the effectiveness-efficacy spectrum using the Rating of Included Trials on the Efficacy-Effectiveness Spectrum (RITES) tool and risk of bias using the Revised Cochrane Risk of Bias tool.

RESULTS

A total of 174 trials met eligibility. RITES domain two trial setting (71.3% vs 16.1%), domain three flexibility of intervention(s) (62.1% vs 23%), and domain four clinical relevance of experimental and comparison intervention(s) (51.7% vs 29.3%) all favored efficacy over effectiveness. Domain one participant characteristic(s) had a slightly greater emphasis on effectiveness compared to efficacy (36.8% vs 44.8%). Most studies (96%) had at least some risk of bias.

CONCLUSION

Over half of the RCTs assessing the treatment effect of joint mobilization and manipulation for neck pain favor efficacy (explanatory) over effectiveness (pragmatic) designs. Future RCTs on this topic should consider a greater emphasis on pragmatic trial design components in order to better reflect real-world translation to clinical practice.

Influence of Sagittal Cervical and Thoracic Range of Motion on Neck Pain Severity in Young White-Collar Workers: A Cross-Sectional Study

Background: Neck pain (NP) is a prevalent musculoskeletal disorder, especially among individuals with sedentary occupations. The interplay between cervical and thoracic spine mobility is hypothesized to contribute significantly to NP severity, yet this relationship requires further exploration. Methods: This cross-sectional study involved 179 young white-collar workers with NP lasting for at least six weeks. Participants were stratified into mild (n = 78) and moderate (n = 101) pain groups based on their scores on the Northwick Park Neck Pain Questionnaire (NPQ). Cervical and thoracic range of motion (ROM) in the sagittal plane was measured using inclinometers. NP severity was further assessed using the NPQ and the Neck Disability Index (NDI). Correlation, regression, and mediation analyses were conducted to investigate the relationship between cervical and thoracic ROM and NP severity. Results: Thoracic ROM was higher in the mild pain group (median: 47.35, IQR: 10.13) than in the moderate pain group (median: 42.10, IQR: 13.60; p < 0.001). The NDI had a negative correlation with thoracic ROM (r = -0.65; p < 0.05) and a positive correlation with cervical ROM (r = 0.84; p < 0.01). Additionally, thoracic ROM mediated the effect of cervical ROM on NP, particularly influencing NDI scores (p < 0.01). Conclusions: This study found a significant association between reduced thoracic ROM and increased NP severity, highlighting the role of thoracic spine mobility in NP among young white-collar workers. Targeted interventions for thoracic dysfunction may reduce compensatory cervical strain and improve NP management, suggesting that thoracic spine assessments should be integrated into routine clinical evaluations.

Thoracic spinal postures and mobility in patients with cervicogenic headache versus asymptomatic healthy controls: A longitudinal study

INTRODUCTION

Studies analyzing postures and mobility of the thoracic spine in the context of cervicogenic headache are missing. Insight in these parameters is needed since the cervical and thoracic spine are biomechanically related.

OBJECTIVE

To compare self-perceived optimal and habitual postures, active-assisted maximal range of motion, and repositioning error of the upper-thoracic and lower-thoracic spine between a cervicogenic headache-group and matched healthy control-group before and after a 30 min-laptop-task.

METHODS

A non-randomized longitudinal design was used to compare thoracic postures and mobility between 18 participants with cervicogenic headache (29-51 years) and 18 matched healthy controls (26-52 years). Outcomes were: self-perceived optimal and habitual postures, active-assisted maximal range of motion, and repositioning error of the upper-thoracic and lower-thoracic spine evaluated in sitting with a 3D-Vicon motion analysis system.

RESULTS

Habitual upper-thoracic postures in the cervicogenic headache-group were significantly (p = .04) less located toward the maximal range of motion for flexion compared to the control-group, self-perceived optimal upper-thoracic posture was significantly (p = .004) more extended in the cervicogenic headache-group compared to the control-group, and self-perceived optimal lower-thoracic posture could not be reestablished in the cervicogenic headache-group after the laptop-task (p = .009).

CONCLUSION

Thoracic postures differ between a cervicogenic headache-group and control-group. These differences were detected by expressing the habitual thoracic posture relative to its maximal range of motion, and by analyzing the possibility of repositioning the thoracic spine after a headache provoking activity. Longitudinal studies are needed to determine the contribution of these musculoskeletal dysfunctions to the pathophysiology of cervicogenic headache.

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

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

The utilization of dry needling and an upper extremity exercise program for individuals with cervicogenic headaches: A pilot study

OBJECTIVE

To investigate whether a combination of dry-needling treatments and upper extremity neuromuscular reeducation exercises can significantly improve neck pain and/or headache-related disability, joint position error, cervical range of motion, and pain pressure threshold in individuals suffering from cervicogenic headache (CGH).

METHODS

This study is a quasi-experimental design. Seven participants met the inclusion criteria and received dry needling to three muscles that reproduced the participant's headache symptoms and completed the Neck Disability Index (NDI), Headache Disability Inventory (HDI), Visual Analog Scale (VAS), and Numeric Pain Rating Scale (NPRS). Participants performed an exercise regimen designed to address strength and mobility of cervical and scapulothoracic musculature.

RESULTS

There were significant improvements seen in cervical range of motion and neck pain-related disability (NDI) during the 4-week treatment period.

CONCLUSION

Dry needling and neuromuscular re-education (NMR) exercises could be effective components of treatment for individuals suffering from CGH to reduce disability and pain.

Autonomic nervous system and endocrine system response to upper or lower cervical spine mobilization in males with persistent post-concussion symptoms: a proof-of-concept trial

INTRODUCTION

The peripheral stress response, consisting of the autonomic nervous system (ANS) and hypothalamic pituitary adrenal-axis (HPA-axis), functions to maintain homeostasis in response to stressors. Cervical spine manual therapy has been shown to differentially modulate the stress response in healthy populations. No study has investigated whether cervical spine mobilizations can differentially modulate the stress response in individuals with persistent post-concussion symptoms (PPCS), a population characterized by a dysfunctional stress response.

METHODS

A randomized, controlled, parallel design trial was performed to investigate whether upper or lower cervical spine mobilization can differentially modulate components of the stress response in individuals with PPCS. The outcomes were salivary cortisol (sCOR) concentration (primary) and the HRV metric, rMSSD, measured with a smartphone application (secondary). Nineteen males diagnosed with PPCS, aged 19-35, were included. Participants were randomly assigned into either intervention group, upper (n = 10) or lower (n = 9) cervical spine mobilization. Each outcome was collected at different time points, pre- and post-intervention. Statistical analyses were performed using the Friedman's Two-Way ANOVA, Mann-Whitney U test, and Wilcoxon Signed Rank Test.

RESULTS

There was a statistically significant within-group reduction in sCOR concentration 30 minutes following lower cervical spine mobilizations and statistically significant within-group increase in rMSSD 30 minutes following upper cervical spine mobilizations.

CONCLUSION

The results of this trial provide preliminary evidence for cervical spine mobilizations to differentially modulate components of the stress response at specific time points. Understanding the mechanisms of the effect of cervical spine mobilizations on the stress response provides a novel rationale for selecting cervical spine mobilizations to rehabilitate individuals with PPCS.

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

BACKGROUND CONTEXT

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

PURPOSE

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

STUDY DESIGN/SETTING

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

PATIENT SAMPLE

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

OUTCOME MEASURES

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

METHODS

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

RESULTS

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

CONCLUSION

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

Can upper cervical manual therapy affect the blink reflex in subjects with migraine and neck pain?

BACKGROUND

Neck pain is a common complaint among migraineurs possibly due to the anatomic connections between cervical and trigeminal afferents in the trigeminocervical complex (TCC). Manual therapy (MT) is used in the management of headache disorders, with demonstrable neurophysiological effects. The blink reflex (BR) is one method of analyzing neurophysiological effects in headache patients. The purpose of this study was to investigate the effect of upper cervical spine MT on BR in subjects with migraine and neck pain.

METHODS & MATERIALS

Twenty subjects were assigned to a medication plus MT (MedMT) group (n = 10) and medication plus sham MT (sham MT) group (n = 10). After random assignment, all patients underwent testing for the BR (R1, R2, R2c responses). Then, subjects in group MedMT and group sham MT received either 4 sessions of MT or sham MT to the upper cervical spine. After completion of the intervention, BR testing was repeated.

RESULTS

There were no significant differences in both side R1 latency between group MT and group sham MT (P > 0.050). For both sides, R2 latencies were significantly prolonged in MedMT group compared with sham MT group (P < 0.050). Subjects in MedMT group showed significant prolongation in right and left R2c latency compared with sham MT group (P < 0.050).

DISCUSSION

The present study demonstrated that upper cervical MT affected trigeminal nociceptive neurotransmission in subjects with migraine and neck pain as reflected by changes in the BR. The increase in BR late response latencies of BR indicates an inhibitory effect of upper cervical spine MT on the TCC in these subjects. Trial Registration: The trial design was registered at the Iranian Registry of Clinical Trials (IRCT ID: IRCT20160621028567N2, url: https://www.irct.ir/) before the first patient was enrolled.

Comparative effectiveness of cervical vs thoracic spinal-thrust manipulation for care of cervicogenic headache: A randomized controlled trial

BACKGROUND

There is ample evidence supporting the use of different manipulative therapy techniques for Cervicogenic Headache (CgH). However, no technique can be singled as the best available treatment for patients with CgH. Therefore, the objective of the study is to find and compare the clinical effects of cervical spine over thoracic spine manipulation and conventional physiotherapy in patients with CgH.

DESIGN, SETTING, AND PARTICIPANTS

It is a prospective, randomized controlled study conducted between July 2020 and January 2023 at the University hospital. N = 96 eligible patients with CgH were selected based on selection criteria and they were divided into cervical spine manipulation (CSM; n = 32), thoracic spine manipulation (TSM; n = 32) and conventional physiotherapy (CPT; n = 32) groups, and received the respective treatment for four weeks. Primary (CgH frequency) and secondary CgH pain intensity, CgH disability, neck pain frequency, neck pain intensity, neck pain threshold, cervical flexion rotation test (CFRT), neck disability index (NDI) and quality of life (QoL) scores were measured. The effects of treatment at various intervals were analyzed using a 3 × 4 linear mixed model analysis (LMM), with treatment group (cervical spine manipulation, thoracic spine manipulation, and conventional physiotherapy) and time intervals (baseline, 4 weeks, 8 weeks, and 6 months), and the statistical significance level was set at P < 0.05.

RESULTS

The reports of the CSM, TSM and CPT groups were compared between the groups. Four weeks following treatment CSM group showed more significant changes in primary (CgH frequency) and secondary (CgH pain intensity, CgH disability, neck pain frequency, pain intensity, pain threshold, CFRT, NDI and QoL) than the TSM and CPT groups (p = 0.001). The same gradual improvement was seen in the CSM group when compared to TSM and CPT groups (p = 0.001) in the above variables at 8 weeks and 6 months follow-up.

CONCLUSION

The reports of the current randomized clinical study found that CSM resulted in significantly better improvements in pain parameters (intensity, frequency and threshold) functional disability and quality of life in patients with CgH than thoracic spine manipulation and conventional physiotherapy.

Physical Therapist Interventions to Reduce Headache Intensity, Frequency, and Duration in Patients With Cervicogenic Headache: A Systematic Review and Network Meta-Analysis

OBJECTIVE

The aim of this study was to assess the efficacy of physical therapist interventions on the intensity, frequency, and duration of headaches, as well as on the quality of life of patients with cervicogenic headache.

METHODS

The following databases were searched up to October 2022: Physiotherapy Evidence Database, Web of Science, Pubmed, and Cochrane Library. Randomized controlled trials assessing the effect of physical therapist interventions on adults with cervicogenic headache were included. Quality appraisal was conducted using the Cochrane risk of bias 2.0 tool and the Confidence in Network Meta-analysis web app. Synthesis methods were conducted in accordance with the Cochrane Handbook.

RESULTS

Of the 28 identified reports, 23 were included in the quantitative synthesis. Manipulation plus dry needling was the highest-ranked intervention to reduce the short-term headache intensity (mean difference [MD] = -4.87; 95% CI = -8.51 to -1.24) and frequency (MD = -3.09; 95% CI = -4.93 to -1.25) when compared to a control intervention. Other high-ranked and clinically effective interventions (when compared to a control intervention) were muscle-energy technique plus exercise (MD = 4.37; 95% CI = -8.01 to -0.74), as well as soft tissue techniques plus exercise (MD = -3.01; 95% CI = -5.1 to -0.92) to reduce short-term headache intensity, and dry needling plus exercise (MD = -2.92; 95% CI = -4.73 to -1.11) to reduce short-term headache frequency. These results were based on a low certainty of evidence.

CONCLUSION

The 4 most highly ranked interventions can be considered in clinical practice. However, no conclusive recommendation can be made due to the low certainty of evidence.

IMPACT

Combined interventions such as spinal joint manipulation plus dry needling and muscle-energy technique or soft tissue techniques or dry needling plus exercises seem to be the best interventions to reduce short-term cervicogenic headache intensity and/or frequency.

Autonomic nervous system and endocrine system response to upper and lower cervical spine mobilization in healthy male adults: a randomized crossover trial

BACKGROUND

Cervical spine mobilizations may differentially modulate both components of the stress response, consisting of the autonomic nervous system and hypothalamic pituitary adrenal-axis, depending on whether the target location is the upper or lower cervical spine. To date, no study has investigated this.

METHODS

A randomized, crossover trial investigated the effects of upper versus lower cervical mobilization on both components of the stress response simultaneously. The primary outcome was salivary cortisol (sCOR) concentration. The secondary outcome was heart rate variability measured with a smartphone application. Twenty healthy males, aged 21-35, were included. Participants were randomly assigned to block-AB (upper then lower cervical mobilization, n = 10) or block-BA (lower than upper cervical mobilization, n = 10), separated by a one-week washout period. All interventions were performed in the same room (University clinic) under controlled conditions. Statistical analyses were performed with a Friedman's Two-Way ANOVA and Wilcoxon Signed Rank Test.

RESULTS

Within groups, sCOR concentration reduced thirty-minutes following lower cervical mobilization (p = 0.049). Between groups, sCOR concentration was different at thirty-minutes following the intervention (p = 0.018).

CONCLUSION

There was a statistically significant reduction in sCOR concentration following lower cervical spine mobilization, and between-group difference, 30 min following the intervention. This indicates that mobilizations applied to separate target locations within the cervical spine can differentially modulate the stress response.

Brain Microstructure and Brain Function Changes in Space Headache by Head-Down-Tilted Bed Rest

INTRODUCTION: Several astronauts have experienced severe headaches during spaceflight, but no studies have examined the associated brain microstructure and functional changes. Head-down-tilted bed rest (HDBR) is a well-established method for studying the physical effects of microgravity on the ground. In this study, we analyzed the changes in brain microstructure and function during headache caused by HDBR using diffusion tensor imaging (DTI) and resting state functional magnetic resonance imaging (R-fMRI).METHODS: We imaged 28 healthy subjects with DTI and R-fMRI in the horizontal supine position and HDBR. Using Tract-Based Spatial Statistics, fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity were compared between the headache and non-headache groups. Additionally, an analysis of functional connectivity (FC) was performed, followed by a correlation analysis between FC and numerical rating scale.RESULTS: HDBR caused headaches in 21 of 28 subjects. DTI analysis showed no significant change in fractional anisotropy after HDBR, whereas axial diffusivity, radial diffusivity, and mean diffusivity increased significantly. R-fMRI analysis showed a significant decrease in FC in several areas after HDBR. The headache group showed significantly higher FC before HDBR, and both groups showed higher FC after HDBR. Correlation analysis showed a positive correlation between FC and numerical rating scale before HDBR but negative after HDBR.DISCUSSION: We demonstrated the image change in the acute phase of space headache by HDBR using DTI and R-fMRI. Changes in brain microstructure and function specific to patients developing headaches may be evaluated by imaging.Goto M, Shibata Y, Ishiyama S, Matsumaru Y, Ishikawa E.

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.

Bibliometric Analysis of Research Trends on Tuina Manipulation for Neck Pain Treatment Over the Past 10 Years

Tuina is an effective treatment for neck pain (NP). However, there has been no bibliometric analysis of the global application and emerging trends of tuina performed for NP. Therefore, this study aimed to provide an overview of the current state and future trends in the field. Articles about tuina for NP, published from January 1, 2013, to January 1, 2023, were searched in the Web of Science Core Collection database. CiteSpace (6.1.R6) and VOSviewer (1.6.18) software were used to analyze annual trends in literature posts, countries, institutions, authors, cited references, and knowledge graphs of keyword co-occurrence, clustering, and burst using standard bibliometric indicators. The final analysis comprised 505 valid documents. The results demonstrate that the number of articles in the field of tuina therapy for NP has gradually increased over the years, showing the most active countries, institutions, journals, and authors. There were 323 keywords in the field, 322 research authors, and 292 research institutions, with the USA having the most publications (n = 140). The most published institution is Vrije University Amsterdam, and the most published journal is the Cochrane Database of Systematic Reviews. Peter R Blanpied is the most influential and most-cited author. Interventions (dry needling, massage therapy, and muscle energy techniques), common treatment sites for NP (upper trapezius), and complications (cervicogenic headache) are the top three frontiers mentioned in the field of tuina research for NP. The bibliometric study showed the current status and trends in clinical research on treating patients with NP using tuina, which may help researchers identify topics of interest and scope for future research in this field.

Headache Characteristics in Chronic Neck Pain Patients with Loss of Cervical Lordosis: A Cross-Sectional Study Considering Cervicogenic Headache

BACKGROUND Loss of cervical lordosis and cervicogenic headache have similar tissue abnormalities, including weakness and atrophy in the neck muscles. Cervicogenic headache is mainly unilateral and is perceived in the occipito-temporo-frontal regions. However, it is not clear whether loss of cervical lordosis is a sign of headache with cervical origin. Herein, we aimed to assess and compare headache characteristics in patients with and without loss of cervical lordosis. MATERIAL AND METHODS This was a cross-sectional study conducted on chronic neck pain patients with (n=38; F/M: 28/10; mean age 33.34±7.73 yrs; range 18 to 45 yrs) and without loss of cervical lordosis (n=38; F/M: 29/9; mean age 33.13±6.41 years; range 20 to 45 years), between May 2019 and November 2019. The 2 groups were assessed and compared for headache characteristics such as frequency, severity, localization, lateralization, duration, and spread scores. Cervical lordosis was assessed on the lateral cervical radiographs by using posterior tangent technique measuring the C2-C7 total cervical spine angle. RESULTS The 2 groups were similar for individual features, including age, sex, employment status, and duration of neck pain (P>0.05). The duration of headache attack was longer in patients with loss of cervical lordosis (5.72±8.12) than in those with normal cervical lordosis (3.29±3.92) (P=0.009). However, there were no significant differences between the 2 groups for headache characteristics, including frequency, severity, localization, lateralization, and spread scores (P>0.05). CONCLUSIONS Patients with loss of cervical lordosis have longer duration of headache attack than those without. Loss of cervical lordosis may be a specific finding associated with longer cervicogenic headache attacks.

Use of Rimegepant in the Management of Cervicogenic Headache Secondary to Trauma: A Case Series

A cervicogenic headache (CH) originates from a cervical source. Multiple diagnostic criteria and treatment strategies for CH are present. Rimegepant is a calcitonin gene-related peptide receptor (CGRP) antagonist. We present a case series of three patients with CH who reported varying degrees of decreased headache intensity after using rimegepant.

The effectiveness of manual and exercise therapy on headache intensity and frequency among patients with cervicogenic headache: a systematic review and meta-analysis

BACKGROUND

Cervicogenic headache is a secondary headache, and manual therapy is one of the most common treatment choices for this and other types of headache. Nonetheless, recent guidelines on the management of cervicogenic headache underlined the lack of trials comparing manual and exercise therapy to sham or no-treatment controls. The main objective of this systematic review and meta-analysis was to assess the effectiveness of different forms of manual and exercise therapy in people living with cervicogenic headache, when compared to other treatments, sham, or no treatment controls.

METHODS

Following the PRISMA guidelines, the literature search was conducted until January 2022 on MEDLINE, CENTRAL, DOAJ, and PEDro. Randomized controlled trials assessing the effects of manual or exercise therapy on patients with cervicogenic headache with headache intensity or frequency as primary outcome measures were included. Study selection, data extraction and Risk of Bias (RoB) assessment were done in duplicate. GRADE was used to assess the quality of the evidence.

RESULTS

Twenty studies were included in the review, with a total of 1439 patients. Common interventions were spinal manipulation, trigger point therapy, spinal mobilization, scapulo-thoracic and cranio-cervical exercises. Meta-analysis was only possible for six manual therapy trials with sham comparators. Data pooling showed moderate-to-large effects in favour of manual therapy for headache frequency and intensity at short-term, small-to-moderate for disability at short-term, small-to-moderate for headache intensity and small for headache frequency at long-term. A sensitivity meta-analysis of low-RoB trials showed small effects in favor of manual therapy in reducing headache intensity, frequency and disability at short and long-term. Both trials included in the sensitivity meta-analysis studied spinal manipulation as the intervention of interest. GRADE assessment showed moderate quality of evidence.

CONCLUSION

The evidence suggests that manual and exercise therapy may reduce headache intensity, frequency and disability at short and long-term in people living with cervicogenic headache, but the overall RoB in most included trials was high. However, a sensitivity meta-analysis on low-RoB trials showed moderate-quality evidence supporting the use of spinal manipulation compared to sham interventions. More high-quality trials are necessary to make stronger recommendations, ideally based on methodological recommendations that enhance comparability between studies. Trial registration The protocol for this meta-analysis was pre-registered on PROSPERO under the registration number CRD42021249277.

Translating the new International IFOMPT Cervical Framework into a framework flowchart for clinical practice and education

BACKGROUND

In 2020, a revised version of the International IFOMPT Cervical Framework was published. This framework provides both physical therapists and educators the necessary information to guide the assessment of the cervical spine region for potential vascular pathologies of the neck in advance of planned Orthopaedic Manual Therapy (OMT) interventions.

OBJECTIVE

The objective was to develop a framework flowchart which is useful in clinical practice and education to assist physical therapists to improve the safety of OMT, and apply this in a case report.

METHODS

The framework was developed in co-creation with manual therapy experts, researchers, educators in manual therapy, patients, medical specialists and the Manual Therapy Association in The Netherlands and Belgium. Manual therapists and patients tested the framework for intelligibility and usefulness.

RESULTS

A framework flowchart is developed and presented, that is easy to use in both clinical practice and education. It is a visual representation of the sequence of steps and decisions needed during the process. A case description of a patient with neck pain and headache is added to illustrate the clinical usefulness of the framework flowchart.

CONCLUSION

The framework flowchart helps physical therapists in their clinical reasoning to provide safe OMT interventions.

TECAR Therapy Associated with High-Intensity Laser Therapy (Hilt) and Manual Therapy in the Treatment of Muscle Disorders: A Literature Review on the Theorised Effects Supporting Their Use

Background: It has been estimated that between 30 and 50 per cent of all injuries that take place throughout participation in a sport are the consequence of soft tissue injuries, and muscle injuries are the primary cause of physical disability. Methods: The current literature review was designed between October 2021 and April 2022, according to the PRISMA standards, using the PubMed, Scopus, and Web of Science databases. At the screening stage, we eliminated articles that did not fit into the themes developed in all subchapters of the study (n = 70), articles that dealt exclusively with orthopaedics (n = 34), 29 articles because the articles had only the abstract visible, and 17 articles that dealt exclusively with other techniques for the treatment of musculoskeletal disorders. The initial search revealed 343 titles in the databases, from which 56 duplicate articles were automatically removed, and 2 were added from other sources. Results: The combination of these three techniques results in the following advantages: It increases joint mobility, especially in stiff joints, it increases the range of motion, accelerates tissue repair, improves tissue stability, and extensibility, and it reduces soft tissue inflammation (manual therapy). In addition, it decreases the concentration of pro-inflammatory mediators and improves capillary permeability, resulting in the total eradication of inflammation (HILT). It warms the deep tissues, stimulates vascularity, promotes the repose of tissues (particularly muscle tissue), and stimulates drainage (TECAR). Conclusions: TECAR therapy, combined with manual therapy and High-Intensity Laser therapy in treating muscle diseases, presented optimal collaboration in the recovery process of all muscle diseases.

Knowledge, beliefs, and attitudes of spinal manipulation: a cross-sectional survey of Italian physiotherapists

BACKGROUND AND OBJECTIVE

High-velocity low-amplitude thrust spinal manipulation (SM) is a recommended and commonly used manual therapy intervention in physiotherapy. Beliefs surrounding the safety and effectiveness of SM have challenged its use, and even advocated for its abandonment. Our study aimed to investigate the knowledge and beliefs surrounding SM by Italian physiotherapists compared with similar practitioners in other countries.

METHODS

An online survey with 41 questions was adapted from previous surveys and was distributed via a mailing list of the Italian Physiotherapists Association (March 22-26, 2020). The questionnaire was divided into 4 sections to capture information on participant demographics, utilization, potential barriers, and knowledge about SM. Questions were differentiated between spinal regions. Attitudes towards different spinal regions, attributes associated with beliefs, and the influence of previous educational background were each evaluated.

RESULTS

Of the 7398 registered physiotherapists, 575 (7.8%) completed the survey and were included for analysis. The majority of respondents perceived SM as safe and effective when applied to the thoracic (74.1%) and lumbar (72.2%) spines; whereas, a smaller proportion viewed SM to the upper cervical spine (56.8%) as safe and effective. Respondents reported they were less likely to provide and feel comfortable with upper cervical SM (respectively, 27.5% and 48.5%) compared to the thoracic (respectively, 52.2% and 74.8%) and lumbar spines (respectively, 46.3% and 74.3%). Most physiotherapists (70.4%) agreed they would perform additional screening prior to upper cervical SM compared to other spinal regions. Respondents who were aware of clinical prediction rules were more likely to report being comfortable with SM (OR 2.38-3.69) and to perceive it as safe (OR 1.75-3.12). Finally, physiotherapists without musculoskeletal specialization, especially those with a traditional manual therapy background, were more likely to perform additional screening prior to SM, use SM less frequently, report being less comfortable performing SM, and report upper cervical SM as less safe (p < 0.001).

DISCUSSION

The beliefs and attitudes of physiotherapists surrounding the use of SM are significantly different when comparing the upper cervical spine to other spinal regions. An educational background in traditional manual therapy significantly influences beliefs and attitudes. We propose an updated framework on evidence-based SM.

Barbed Suture versus Interrupted Suture in Posterior Cervical Spine Surgery: Are They Equivalent?

Introduction

Posterior cervical spine approaches have been associated with increased rates of wound complications compared to anterior approaches. While barbed suture wound closure for lumbar spine surgery has been shown to be safe and efficacious, there is no literature regarding its use in posterior cervical spine surgery. In a cohort of patients undergoing elective posterior cervical spine surgery, we sought to compare postoperative complication rates between barbed and traditional interrupted suture closure.

Methods

A retrospective review of demographics, past medical history, and operative and postoperative variables collected from a prospective registry between July 1, 2016, and June 30, 2020 was undertaken. All patients 18 years old and above undergoing elective posterior cervical fusion were included. The primary outcome of interest was wound complications, including surgical site infection (SSI), dehiscence, or hematoma. In addition, numerical rating scale (NRS) neck pain (NP), NRS arm pain (AP), Neck Disability Index (NDI), and operative time were collected. A variety of statistical tests were used to compare the two suture groups.

Results

Of 117 patients undergoing posterior cervical fusion, 89 (76%) were closed with interrupted suture and 28 (24%) with barbed suture. The interrupted cohort were more likely to have >1 comorbidity (p<0.001), diabetes mellitus (p=0.013), and coronary artery disease (p=0.002). No difference in postoperative wound complications between interrupted/barbed sutures was observed after univariate (OR 1.07, 95% CI: 0.27-4.25, p=0.927) and multivariable logistic regression analysis (OR 0.77, 95% CI: 0.15-4.00, p=0.756). Univariate logistic regression revealed no differences in achieving minimal clinically important difference (MCID) NRS-NP (OR 0.73, 95% CI: 0.28-1.88, p=0.508) or NRS-AP (OR 0.68, 95% CI: 0.25-1.90, p=0.464) at 3 months between suture groups. The interrupted suture group was less likely to achieve MCID NDI at 3 months (OR 0.29, 95% CI: 0.11-0.80, p=0.016).

Conclusions

Barbed suture closure in posterior cervical spine surgery does not lead to higher rates of postoperative wound complications/SSI compared to traditional interrupted fascial closure.

Dry needling and upper cervical spinal manipulation in patients with temporomandibular disorder: A multi-center randomized clinical trial

OBJECTIVE

To compare the effects of dry needling and upper cervical spinal manipulation with interocclusal splint therapy, diclofenac, and temporomandibular joint (TMJ) mobilization in patients with temporomandibular disorder (TMD).

METHODS

One hundred-twenty patients with TMD were randomized to receive six treatment sessions of dry needling plus upper cervical spinal manipulation (n = 62) or interocclusal splint therapy, diclofenac, and joint mobilization to the TMJ (n = 58).

RESULTS

Patients receiving dry needling and upper cervical spinal manipulation experienced significantly greater reductions in jaw pain intensity over the last 7 days (VAS: F = 23.696; p < 0.001) and active pain-free mouth opening (F = 29.902; p < 0.001) than those receiving interocclusal splint therapy, diclofenac, and TMJ mobilization at the 3-month follow-up.

CONCLUSION

Dry needling and upper cervical spinal manipulation was more effective than interocclusal splint therapy, diclofenac, and TMJ mobilization in patients with TMD.

Effectiveness of manual therapy in the treatment of cervicogenic headache: A systematic review

OBJECTIVE

The aim of this study was to identify the manual therapy (MT) methods and techniques that have been evaluated for the treatment of cervicogenic headache (CH) and their effectiveness.

BACKGROUND

MT seems to be one of the options with the greatest potential for the treatment of CH, but the techniques to be applied are varied and there is no consensus on which are the most indicated.

METHODS

A systematic search in Scopus, Medline, PubMed, Cinahl, PEDro, and Web of Science with the terms: secondary headache disorders, physical therapy modalities, musculoskeletal manipulations, cervicogenic headache, manual therapy, and physical therapy. We included articles published from 2015 to the present that studied interventions with MT techniques in patients with CH. Two reviewers independently screened 365 articles for demographic information, characteristics of study design, study-specific intervention, and results. The Oxford 2011 Levels of Evidence and the Jadad scale were used.

RESULTS

Of a total of 14 articles selected, 11 were randomized control trials and three were quasi-experimental studies. The techniques studied were: spinal manipulative therapy, Mulligan's Sustained Natural Apophyseal Glides, muscle techniques, and translatory vertebral mobilization. In the short-term, the Jones technique on the trapezius and ischemic compression on the sternocleidomastoid achieved immediate improvements, whereas adding spinal manipulative therapy to the treatment can maintain long-term results.

CONCLUSIONS

The manual therapy techniques could be effective in the treatment of patients with CH. The combined use of MT techniques improved the results compared with using them separately. This review has methodological limitations, such as the inclusion of quasi-experimental studies and studies with small sample sizes that reduced the generalizability of the results obtained.

Evaluation and Treatment of Trigeminal Symptoms of Cervical Origin After a Motor-Vehicle Crash: A Case Report With 9-Month Follow-up

Objective

The purpose of this case report is to describe the management of a patient with trigeminal symptoms of cervical origin after a motor-vehicle crash (MVC).

Clinical Features

After a head-on MVC, a 65-year-old woman presented with complaints of dizziness, headaches, facial tingling, visual disturbance, tinnitus, loss of cervical motion, and pain in the cervical spine.

Intervention and Outcome

The intervention applied was manipulation of the left C1-C2 and right C2-C3, with targeted exercise to strengthen the cervical musculature. After 4 weeks of treatment, the patient reported improvement in functional tasks and reduction in overall pain, headaches, facial tingling, tinnitus, and dizziness. At a 9-month follow-up, the patient had no report of facial tingling, tinnitus, loss of motion, or eye pain.

Conclusion

This patient with trigeminal symptoms of cervical origin after an MVC responded well to manual therapy to the cervical spine as part of a combination of services.

Effectiveness of spinal mobilization and postural correction exercises in the management of cervicogenic headache: A randomized controlled trial

OBJECTIVE

The study aims to assess the effect of spinal mobilization and postural correction exercises in patients suffering from cervicogenic headache.

METHODS

A randomized controlled trial was conducted with 72 patients. Patients were randomly allocated into three groups: spinal mobilization (n = 24), postural correction exercises (n = 24), and control group (n = 24). The primary outcome measure was headache impact test-6, and secondary outcomes were headache intensity, neck pain intensity, and neck pain-related disability measured at baseline, postintervention, and follow-up period.

RESULT

Comparison of baseline data (at 0 weeks) among groups showed a statistically nonsignificant difference. There was statistically significant improvement at postintervention (immediately after fourth week) in postural correction exercises group [headache disability: 14.95 ± 7.91 (p < .001); headache intensity: 2.58 ± 1.24 (p < .001); neck disability: 27.66 ± 18.71 (p < .001); neck pain: 1.91 ± 1.44 (p < .001)] and spinal mobilization group [headache disability: 13.83 ± 6.21 (p < .001); headache intensity: 2.29 ± 1.23 (p < .001); neck disability: 23.39 ± 19.51 (p < .001); neck pain: 1.72 ± 0.84 (p < .001)] as compared to the control group. The result of within-group analysis suggests that there was a statistically significant improvement in postintervention (immediately after fourth week) and follow-up (immediately after eighth week) scores as compared to baseline (at 0 weeks) scores for all outcomes in postural correction exercises [headache disability (p < .001), headache intensity (p < .001), neck disability (p < .001), neck pain (p < 0 .001)] as well as in spinal mobilization group [headache disability (p < .001), headache intensity (p < .001), neck disability (p < .001), neck pain (p < .001 for pre versus post; p = .001 for pre versus follow-up)]. There was a statistically nonsignificant difference between postintervention and follow-up scores of all the outcomes in the postural correction exercise and spinal mobilization group, which indicates that improvement in these groups was maintained during the follow-up period.

CONCLUSION

Spinal mobilization and postural correction exercises are effective in the management of cervicogenic headache.

Enlarged Vertebral Venous Plexus Alleviated Intracranial Hypertension-Related Symptoms in Patients with Bilateral Transverse Sinus Stenosis

BACKGROUND

Enlarged vertebral venous plexus (EVVP) was often observed in patients with bilateral transverse sinus stenosis (BTSS). The purpose of this study was to investigate the physiological role of EVVP in BTSS patients.

METHODS

Forty-five BTSS patients and 92 normal controls were prospectively recruited from January 2014 to December 2019. The index of transverse sinus stenosis (ITSS) was used for the assessment of BTSS severity. Subjects underwent a standard lumbar puncture to measure the intracranial pressure (ICP). Papilledema and tinnitus were evaluated by using Frisén's grade and questionnaires for Tinnitus Handicap Inventory (THI), respectively. The intensity and impact of headache were assessed by using 10-point Numeric Pain Rating Scale and six-item Headache Impact Test, respectively.

RESULTS

The BTSS group had more subjects with intracranial hypertension (IH) and less subjects with normal ICP than normal controls (p < 0.01; p < 0.01). BTSS patients had higher ICP than normal controls (p < 0.01). ICP was significantly lower in BTSS patients with EVVP than in those without EVVP (p < 0.01). No significant difference in ICP was found between normal controls with EVVP and those without EVVP (p = 0.99). A similar incidence of EVVP in BTSS patients and normal controls was found (p = 0.86). BTSS patients with IH exhibited a lower incidence of EVVP than those with normal ICP and overlapping ICP (p < 0.01; p < 0.01). The incidence of EVVP was not correlated with ITSS (p = 0.81). EVVP, rather than ITSS, correlated with ICP (p = 0.01). Furthermore, EVVP alleviated papilledema evaluated by Frisén's grade and tinnitus evaluated by the THI score in BTSS patients (p = 004; p = 0.02).

CONCLUSIONS

EVVP in normal controls is a congenital phenomenon that exerts no impact on ICP. However, the presence of EVVP reduces ICP and alleviates IH-related papilledema and tinnitus in BTSS patients.

The Unknown Prevalence of Postrandomization Bias in 15 Physical Therapy Journals: A Methods Review

OBJECTIVES

To determine the prevalence of prospective clinical trial registration and postrandomization bias in published musculoskeletal physical therapy randomized clinical trials (RCTs).

DESIGN

A methods review.

LITERATURE SEARCH

Articles indexed in MEDLINE and published between January 2016 and July 2020 were included.

STUDY SELECTION CRITERIA

Two independent blinded reviewers identified the RCTs using Covidence. We included RCTs related to musculoskeletal interventions that were published in International Society of Physiotherapy Journal Editors member journals.

DATA SYNTHESIS

Data were extracted independently for the variables of interest from the identified RCTs by 2 blinded reviewers. The data were presented descriptively or in frequency tables.

RESULTS

One hundred thirty-eight RCTs were identified. One third of RCTs were consistent with their prospectively registered intent (49/138); consistency with prospectively registered intent could not be determined for two thirds (89/138) of the RCTs. Four RCTs (8%)reported inconsistent results with the primary aims and 7 (14%) with the outcomes from the prospective clinical trial registry, despite high methodological quality (Physiotherapy Evidence Database [PEDro] scale score). Differences between prospectively registered and non-prospectively registered RCTs for PEDro scale scores had a medium effect size (r = 0.30). Two of 15 journals followed their clinical trial registration policy 100% of the time; in 1 journal, the published RCTs were consistent with the clinical trial registration.

CONCLUSION

Postrandomization bias in musculoskeletal physical therapy RCTs could not be ruled out, due to the lack of prospective clinical trial registration and detailed data analysis plans. J Orthop Sports Phys Ther 2021;51(11):542-550. Epub 21 Sep 2021. doi:10.2519/jospt.2021.10491.

Immediate effects of thoracic manipulation on cervical joint position sense in individuals with mechanical neck pain: A randomized controlled trial

BACKGROUND

Performing thoracic manipulations for neck pain can result in immediate improvements in neck function.

OBJECTIVE

The aim of this study was to investigate the immediate effects of thoracic manipulation on cervical joint position sense and cervical range of motion in individuals with chronic mechanical neck pain.

METHODS

Eighty male volunteers between 18-25 years and having chronic or recurrent neck or shoulder pain of at least 3 months duration with or without arm pain were randomized into two groups: Thoracic Manipulation Group (TMG:50) and Control Group (CG:30), with a pretest-posttest experimental design. The TMG was treated with thoracic extension manipulation while the CG received no intervention. Cervical joint position error and cervical range of motion of the individuals were assessed at baseline and 5 minutes later.

RESULTS

There was no difference in demographic variables such as age (p= 0.764), Body Mass Index (p= 0.917) and Neck Pain Disability Scale (NPDS) scores (p= 0.436) at baseline outcomes between TMG and CGs. Joint position error outcomes between the two groups following intervention were similar in all directions at 30 and 50 degrees. Differences in range of motion following intervention in neck flexion (p< 0.001) and right rotation (p= 0.004) were higher in TMG compared to CG.

CONCLUSIONS

A single session of thoracic manipulation seems to be inefficient on joint position sense in individuals with mild mechanical neck pain. However, thoracic manipulation might be an effective option to increase flexion and rotation of the cervical region as an adjunctive to treatment.

Effectiveness of a manual therapy protocol based on articulatory techniques in migraine patients. A randomized controlled trial

BACKGROUND

Physiotherapy is used as a non-pharmacological treatment for migraine. However, controversy exists over whether articulatory manual techniques are effective in some aspects related to migraine.

OBJECTIVES

To assess the effectiveness of a manual therapy protocol based on articulatory techniques in pain intensity, frequency of episodes, migraine disability, quality of life, medication intake and self-reported perceived change after treatment in migraine patients.

DESIGN

Randomized controlled trial.

METHODS

Fifty individuals with migraine were randomized into the experimental group, which received manual therapy based on articulatory techniques (n = 25), or the placebo group (n = 25). The intervention lasted 4 weeks and included 4 sessions. Patients were assessed before (T1), after (T2) and at a one-month follow-up following the intervention (T3). The instruments used were the Migraine Disability Assessment (MIDAS) questionnaire, the Short Form-36 Health Survey (SF-36), the medication intake and The Patients' Global Impression of Change scale.

RESULTS

In comparison with placebo group, manual therapy patients reported significant effects on pain intensity at T2 (p < 0.001; d = 1.15) and at T3 (p < 0.001; d = 1.13), migraine disability at T3 (p < 0.05; d = 0.69), physical quality of life at T2 (p < 0.05; d = 0.72), overall quality of life at T2 (p < 0.05; d = 0.60), decrease in medication intake at T2 (p < 0.001; d = 1.11) and at T3 (p < 0.05; d = 0.77) and self-reported perceived change after treatment at T2 and T3 (p < 0.001). No serious adverse events were reported.

CONCLUSIONS

The application of a manual therapy protocol based on articulatory techniques reduced pain intensity, migraine disability, and medication intake, while improving quality of life in patients with migraine.

Thoracic spine thrust manipulation for individuals with cervicogenic headache: a crossover randomized clinical trial

Objective: To determine if thoracic spine manipulation (TSM) improves pain and disability in individuals with cervicogenic headache (CeH).Methods: A randomized controlled crossover trial was conducted on 48 participants (mean age: 34.4 years) with CeH symptoms. Participants were randomized to 6 sessions of TSM or no treatment (Hold) and after 4-weeks, groups crossed over. Outcomes were collected at 4, 8 and 12 weeks and included: headache disability inventory (HDI), neck disability index (NDI), and the global rating of change (GRC). Outcomes were analyzed using a linear mixed-effects model with Bonferroni correction. Odds of achieving the minimal clinically important difference (MCID) on the GRC of +4 or greater were also calculated. Scores at 4 weeks represent the only timepoint where 1 group is fully treated and other group has not received any treatment.Results: Comparing hold to active treatment, HDI were not significantly different between groups (mean difference = 7.39, 95 CI: -4.39 to 19.18; P = 0.214) at any timepoint; the NDI was significant (mean difference = 6.90, 95 CI: 0.05 to 13.75; P = 0.048) at 4 weeks. Odds of achieving the +4 MCID on the GRC (OR = 38.0, 95 CI: 6.6 to 220.0; p < 0.001) favored TSM at 4 weeks.Conclusion: TSM had no effect on headache-related disability but resulted in significant improvements in neck-related disability and participant reported perceived improvement. Future studies are needed to examine the long-term impact of TSM in this population.

Short-term effect of adding graston technique to exercise program in treatment of patients with cervicogenic headache: a single-blinded, randomized controlled trial

BACKGROUND

Physical Therapists may use the Graston technique to relieve soft-tissue restrictions and pain in the upper cervical region. However, no studies have tested the efficacy of the Graston technique in patients with cervicogenic headache.

AIM

To investigate the effect of adding the Graston technique to an exercise program on pain intensity, neck disability, cervical range of motion, headache frequency and duration, and medication intake in subjects with cervicogenic headache.

DESIGN

A single-blinded(assessor), randomized controlled trial.

SETTING

Outpatient rehabilitation clinic.

POPULATION

Sixty patients,35 to 50 years old, with cervicogenic headache have participated in the study. Patients were recruited from the outpatient clinics of Tala general hospital in Menoufia governorate.

METHODS

Patients were assigned randomly into two groups. Patients in the study group received the Graston technique in addition to an exercise program, while patients in the control group received the exercise program only. All patients received 3 sessions a week for 4 weeks. The primary outcome measure was the visual analogue scale(VAS), while the secondary outcome measures were neck disability index (NDI), cervical range of motion(CROM), headache frequency and duration, and medication intake. All outcomes were measured at baseline, after 2 weeks as well as after 4 weeks of intervention.

RESULTS

After 2 weeks of the treatment, statistically significant differences were found in all the measured outcomes (p< 0.05) in favor of the Graston group except for neck extension(p=0.08). After 4 weeks of the intervention, statistically significant differences were found in all the measured outcomes (p< 0.05) in favor of the Graston group.

CONCLUSIONS

Short-term effect of using the Graston technique in combination with an exercise program can reduce pain, decrease headache frequency and duration, and medication intake more than the exercise program alone in the medium-term. However, although the study results for NDI and neck ROM were statistically significant, it is neither clinically relevant change nor clearly outside the range of measurement error.

[The Second Short Form of the McGill Pain Questionnaire as the useful additional tool for differential diagnostics of migraine and cervicogenic headache]

OBJECTIVE

To study the effectiveness of the Second Short Form of the McGill Pain Questionnaire (SF-MPQ-2) as an instrument for assessment and comparison of quantitative characteristics of pain in patients with chronic musculoskeletal impairment of the cervical spine and nonspecific neck pain accompanied by chronic migraine or cervicogenic headache (CeH).

MATERIAL AND METHODS

Forty-nine patients, aged from 19 to 60 years (mean age 42.8±10.4), were divided into 2 comparable by age and gender groups with migraine (n=18) and CeH (n=31). Neck pain and headache intensity was measured by the 11-points Numerical Rating Scale (NRS). Quality of pain and related symptoms were measured by SF-MPQ-2. Multidisciplinary and multimodal approaches were applied for treatment, including several modalities of manual therapy.

RESULTS

Headache intensity was higher in the migraine group in comparison with the CeH group (7.8±1.7 vs 6.0±1.5, respectively; p<0.05). No significant differences in neck pain intensity were found (6.2±1.8 vs 5.3±1.7; p=0.08). Patients with migraine usually chose more descriptors than patients with CeH (14 vs 4, respectively) and higher range of their intensity (p<0.001). By the end of treatment session, the number of descriptors and their intensity decreased significantly on all SF=MPQ-2 scales (p<0.001) in both groups. Most patients of migraine and CeH group were satisfied with treatment (83% and 97%, respectively) and marked «much improved» and «very much improved» on the 7-point Patient Global Impression of Change scale.

CONCLUSION

SF-MPQ-2 is a useful tool for differential diagnosis of migraine and CeH, as it contains the sufficient number of descriptors and the scale for measuring their intensity.

Effectiveness of Mulligan manual therapy over exercise on headache frequency, intensity and disability for patients with migraine, tension-type headache and cervicogenic headache - a protocol of a pragmatic randomized controlled trial

BACKGROUND

Non - pharmacological management of migraine, tension-type headache (TTH), and cervicogenic headache (CGH) may include spinal manual therapy and exercise. Mulligan Manual Therapy (MMT) utilizes a protocol of headache elimination procedures to manage headache parameters and associated disability, but has only been evaluated in CGH. There is little evidence for its effectiveness in migraine and TTH. This study aims to determine the effectiveness of MMT and exercise over exercise and placebo in the management of migraine, TTH, and CGH.

METHODS

This pragmatic trial is designed as a prospective, three-armed randomised controlled trial in a clinical setting provided at a general hospital physiotherapy department. Two hundred ninety-seven participants with a diagnosis of migraine, TTH or CGH based on published headache classification guidelines will be included. An assessor blind to group allocation will measure outcomes pre-and post-intervention as well as 3 and 6 months after commencement of treatment. Participants will be allocated to one of the three groups: MMT and exercise; placebo and exercise; and exercise alone. The primary outcome measure is headache frequency. Secondary outcome measures are headache duration and intensity, medication intake, pressure pain threshold (PPT), range of motion recorded with the flexion rotation test, and headache disability recorded with Headache Activities of Daily Living Index (HADLI). The intention-to-treat principle will be followed for statistical analysis. Between groups differences for all outcome measures at baseline and at reassessment points and 95% confidence intervals will be calculated using a mixed model ANOVA. Post hoc tests will be conducted to identify any significant difference between groups and over time.

DISCUSSION

This pragmatic study will provide evidence for the effectiveness of MMT when compared with a placebo intervention and exercise on headache frequency, intensity, and disability. Limitations are that baseline evaluation of headache parameters may be affected by recall bias. External validity will be limited to the population with a minimum 1-year history of headache. The HADLI is not yet extensively evaluated for its psychometric properties and association between PPT and headache parameters is lacking. Performance bias is inevitable as a single therapist will be delivering all interventions.

TRIAL REGISTRATION

The trial was registered prospectively under the Clinical Trial Registry India (Registration number: CTRI/2019/06/019506 , dated on 03/06/2019). .

Physical therapy treatment of a pediatric patient with symptoms consistent with a spinal cord injury without radiographic abnormality: A retrospective case report

BACKGROUND

A spinal cord injury without radiographic abnormality (SCIWORA) is a relatively uncommon event that occurs in children following cervical trauma primarily due to sports-related injuries or physical abuse.

CASE DESCRIPTION

This case report describes an 11-year-old wrestler that developed signs and symptoms consistent with a SCIWORA following neck trauma during competition. Despite all diagnostic tests being inconclusive, the patient demonstrated increased cervical, thoracic, and lumbar paraspinal tone along with pain, loss of sensation, loss of mobility, and weakness of the lower extremities. As a result, the patient was confined to a wheelchair and required maximum assistance to transfer and ambulate with a walker. The patient was referred to physical therapy nine days after the traumatic event, where he received interferential current with moist heat, myofascial release of paraspinal muscles, functional exercise, gait training, and spinal manipulative therapy targeting the cervical, thoracic, and lumbar vertebrae.

OUTCOME

After 13 physical therapy treatments over 5-weeks, the patient was able to ambulate independently and perform all activities of daily living without pain or functional limitation. The following case report outlines this patient's successful journey toward recovery.

CONCLUSION

This case report suggests that spinal manipulative therapy may be a safe and effective intervention when used within a multi-modal treatment strategy for patients with signs and symptoms consistent with SCIWORA. Moreover, spinal manipulative therapy may be considered a beneficial treatment in some pediatric patients. However, this report describes a single patient, and further research is required on the use of spinal manipulation in this patient population.

Effects of SNAG mobilization combined with a self-SNAG home-exercise for the treatment of cervicogenic headache: a pilot study

INTRODUCTION

Cervicogenic headache (CGH) may originate from the C1-C2 zygapophyseal joints. CGH is often associated with loss of range of motion (ROM), specific to this segment, and measurable by the cervical flexion-rotation test (CFRT). The main purposes of the study were: 1) to investigate the immediate effect of C1-C2 rotation SNAG mobilizations plus C1-C2 self-SNAG rotation exercise for patients with CGH and 2) to explore the link between the CFRT results and treatment response.

METHODS

A prospective quasi-experimental single-arm design was used where patients with CGH received eight physical therapy treatments using a C1-C2 rotational SNAG technique combined with a C1-C2 self-SNAG rotation exercise over a four-week period. Outcome measures were pain intensity/frequency and duration, active cervical ROM, CFRT, neck-related and headache-related self-perceived physical function, fear-avoidance beliefs, pain catastrophizing and kinesiophobia.

RESULTS

The intervention produced strong effects on pain intensity, CFRT, physical function and pain catastrophizing. Moderate improvement was noted on active cervical ROM and on fear-avoidance beliefs and kinesiophobia. No link was found between pre-intervention CFRT ROM and treatment response.

CONCLUSION

SNAG mobilization combined with a self-SNAG exercise resulted in favorable outcomes for the treatment of CGH on patient-important and biomechanical outcomes, as well as pain-related cognitive-affective factors.

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

OBJECTIVES

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

DESIGN

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

METHODS

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

RESULTS

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

CONCLUSION

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

Spinal manipulation and perineural electrical dry needling in patients with cervicogenic headache: a multicenter randomized clinical trial

BACKGROUND CONTEXT

Spinal manipulation, spinal mobilization, and exercise are commonly used in individuals with cervicogenic headache (CH). Dry needling is being increasingly used in the management of CH. However, questions remain about the effectiveness of these therapies and how they compare to each other.

PURPOSE

The present study aims to compare the combined effects of spinal manipulation and dry needling with spinal mobilization and exercise on pain and disability in individuals with CH.

STUDY DESIGN/SETTING

Randomized, multicenter, parallel-group trial.

PATIENT SAMPLE

One hundred forty-two patients (n=142) with CH from 13 outpatient clinics in 10 different states were recruited over a 36-month period.

OUTCOME MEASURES

The primary outcome was headache intensity as measured by the Numeric Pain Rating Scale. Secondary outcomes included headache frequency and duration, disability (Neck Disability Index), medication intake, and the Global Rating of Change (GROC). Follow-up assessments were taken at 1 week, 4 weeks, and 3 months.

METHODS

Patients were randomized to receive upper cervical and upper thoracic spinal manipulation plus electrical dry needling (n=74) or upper cervical and upper thoracic spinal mobilization and exercise (n=68). In addition, the mobilization group also received a program of craniocervical and peri-scapular resistance exercises; whereas, the spinal manipulation group also received up to eight sessions of perineural electrical dry needling. The treatment period for both groups was 4 weeks. The trial was prospectively registered at ClinicalTrials.gov (NCT02373605). Drs Dunning, Butts and Young are faculty within the AAMT Fellowship and teach postgraduate courses in spinal manipulation, spinal mobilization, dry needling, exercise and differential diagnosis. The other authors declare no conflicts of interest. None of the authors received any funding for this study.

RESULTS

The 2 × 4 analysis of covariance revealed that individuals with CH who received thrust spinal manipulation and electrical dry needling experienced significantly greater reductions in headache intensity (F=23.464; p<.001), headache frequency (F=13.407; p<.001), and disability (F=10.702; p<.001) than those who received nonthrust mobilization and exercise at a 3-month follow-up. Individuals in the spinal manipulation and electrical dry needling group also experienced shorter duration of headaches (p<.001) at 3 months. Based on the cutoff score of ≥+5 on the GROC, significantly (X²=54.840; p<.001) more patients (n=57, 77%) within the spinal manipulation and electrical dry needling group achieved a successful outcome compared to the mobilization and exercise group (n=10, 15%) at 3-month follow-up. Between-groups effect sizes were large (0.94<standardized mean score difference<1.25) in all outcomes in favor of the spinal manipulation and electrical dry needling group at 3 months. In addition, significantly (X²=29.889; p<.001) more patients in the spinal manipulation and electrical dry needling group (n=49, 66%) completely stopped taking medication for their pain compared to the spinal mobilization and exercise group (n=14, 21%) at 3 months.

CONCLUSION

Upper cervical and upper thoracic high-velocity low-amplitude thrust spinal manipulation and electrical dry needling were shown to be more effective than nonthrust mobilization and exercise in patients with CH, and the effects were maintained at 3 months.

Approaches to cervical spine mobilization for neck pain: a pilot randomized controlled trial

Study design

Pilot randomized controlled trial.

Background

Better understanding of the relative effectiveness of different approaches to cervical spine mobilization has been identified as a research priority in manual therapy practice. Two distinct approaches to the practice of mobilization have emerged in recent years, based on different reasoning models for selection of mobilization techniques. The objective of this pilot study was to assess feasibility aspects for a future randomized clinical trial by exploring short-term pain and disability outcomes after a single treatment with pragmatic versus prescriptive approaches to cervical mobilization for people with recent-onset neck pain at 48-h follow-up after randomization.

Methods

Twenty adults with a new episode of mechanical neck pain were randomly allocated to either pragmatic or prescriptive mobilization intervention groups. The pragmatic group received a single treatment of cervical mobilization with the technique, target segment, and grade selected by their treating therapist. The prescriptive group received a single treatment of standardized mobilization with techniques similar to a previous mobilization clinical trial. Feasibility outcomes were recruitment rates, randomization audit and completion of treatment and follow-up per protocol. The primary clinical outcome of interest was disability level measured at 48-h follow-up after randomization.

Results

Recruitment rates were approximately 2.5 participants per week and 100% of eligible participants were deemed suitable for treatment with cervical mobilization. There was sufficient variety in the range of pragmatic treatments selected and the data collection process imposed minimal burden on participants.

Conclusions

Our results provide supporting evidence for the feasibility of a future larger scale randomized clinical trial.

Pragmatic application of manipulation versus mobilization to the upper segments of the cervical spine plus exercise for treatment of cervicogenic headache: a randomized clinical trial

BACKGROUND

The effectiveness of manipulation versus mobilization for the management of spinal conditions, including cervicogenic headache, is conflicting. However, a pragmatic approach comparing manipulation to mobilization has not been examined in a patient population with cervicogenic headache.

OBJECTIVES

To evaluate the effectiveness of manipulation compared to mobilization applied in a pragmatic fashion for patients with cervicogenic headache.

METHODS

Forty-five (26 females) patients with cervicogenic headache (mean age 47.8 ± SD 16.9 years) were randomly assigned to receive either pragmatically selected manipulation or mobilization. Outcomes were measured at baseline, the second visit, discharge, and 1-month follow-up and included the Neck Disability Index (NDI), Numeric Pain Rating Scale (NPRS), the Headache Impact Test (HIT-6), the Global Rating of Change (GRC), the Patient Acceptable Symptoms Scale (PASS). The primary aim (effects of treatment on disability and pain were examined with a mixed-model analysis of variance (ANOVA), with treatment group (manipulation versus mobilization) as the between subjects variable and time (baseline, 48 hours, discharge and follow-up) as the within subjects variable.

RESULTS

The interaction for the mixed model ANOVA was not statistically significant for NDI (p = 0.91), NPRS (p = 0.81), or HIT (p = 0.89). There was no significant difference between groups for the GRC or PASS.

DISCUSSION AND CONCLUSION

The results suggest that manipulation has similar effects on disability, pain, GRC, and cervical range of motion as mobilization when applied in a pragmatic fashion for patients with cervicogenic headaches.

Dry needling as a novel intervention for cervicogenic somatosensory tinnitus: a case study

Tinnitus is defined as conscious perception of sound in the absence of a corresponding external stimulus. A condition that affects 10 - 15% of the adult population, tinnitus may be caused by an interaction between the somatosensory and auditory system, more formally known as somatosensory tinnitus. Cervicogenic somatosensory tinnitus is a subgroup of somatosensory tinnitus involving anatomical structures and physiological mechanisms associated with the cervical spine. A limited number of studies have reported inconsistent outcomes for treating cervicogenic somatosensory tinnitus with conservative treatment strategies such as manual therapy and exercise. However, dry needling is a skilled, manual therapy intervention that has recently gained popularity among the physical therapy profession that may be useful for both evaluating and treating the condition. The following case report describes the use of dry needling to evaluate and treat a patient with cervical somatosensory tinnitus and concurrent cervicogenic headaches. Physical therapy that targeted the muscles of the upper cervical spine with dry needling resulted in a meaningful reduction in cervicogenic somatosensory tinnitus, and the improvements persisted at 1-year follow-up. Further research, including randomized control trials, is warranted to fully determine the potential of dry needling to treat cervicogenic somatosensory tinnitus.

Post-traumatic cephalalgia

After traumatic brain injury (TBI), a host of symptoms of varying severity and associated functional impairment may occur. One of the most commonly encountered and challenging to treat are the post-traumatic cephalalgias. Post-traumatic cephalalgia (PTC) or headache is often conceptualized as a single entity as currently classified using the ICHD-3. Yet, the terminology applicable to the major primary, non-traumatic, headache disorders such as migraine, tension headache, and cervicogenic headache are often used to specify the specific type of headache the patients experiences seemingly disparate from the unitary definition of post-traumatic headache adopted by ICHD-3. More complex post-traumatic presentations attributable to brain injury as well as other headache conditions are important to consider as well as other causes such as medication overuse headache and medication induced headache. Treatment of any post-traumatic cephalalgia must be optimized by understanding that there may be more than one headache pain generator, that comorbid traumatic problems may contribute to the pain presentation and that pre-existing conditions could impact both symptom complaint, clinical presentation and recovery. Any treatment for PTC must harmonize with ongoing medical and psychosocial aspects of recovery.

Immediate and Short-Term Effects of Upper Cervical High-Velocity, Low-Amplitude Manipulation on Standing Postural Control and Cervical Mobility in Chronic Nonspecific Neck Pain: A Randomized Controlled Trial

This study aimed to determine the immediate and short-term effects of a single upper cervical high-velocity, low-amplitude (HVLA) manipulation on standing postural control and cervical mobility in chronic nonspecific neck pain (CNSNP). A double-blinded, randomized placebo-controlled trial was performed. Forty-four patients with CNSNP were allocated to the experimental group (n = 22) or control group (n = 22). All participants were assessed before and immediately after the intervention, with a follow-up on the 7th and 15th days. In each evaluation, we assessed global and specific stabilometric parameters to analyze standing postural balance and performed the cervical flexion-rotation test (CFRT) to analyze upper cervical mobility. We obtained statistically significant differences, with a large effect size, in the limited cervical rotation and global stabilometric parameters. Upper cervical HVLA manipulation produced an improvement in the global stabilometric parameters, significantly decreasing the mean values of velocity, surface, path length, and pressure in all assessments (p < 0.001; ƞ 2 p = 0.323–0.856), as well as significantly decreasing the surface length ratio (L/S) on the 7th (−0.219 1/mm; p = 0.008; 95% confidence interval (CI): 0.042–0.395) and 15th days (−0.447 1/mm; p < 0.001; 95% CI: 0.265–0.629). Limited cervical rotation values increased significantly immediately after manipulation (7.409°; p < 0.001; 95% CI: 6.131–8.687) and were maintained during follow-up (p < 0.001). These results show that a single upper cervical HVLA manipulation produces an improvement in standing postural control and increases the rotational range of motion (ROM) in the upper cervical spine in patients with CNSNP.

Effectiveness of Cervical Spine High-Velocity, Low-Amplitude Thrust Added to Behavioral Education, Soft Tissue Mobilization, and Exercise for People With Temporomandibular Disorder With Myalgia: A Randomized Clinical Trial

OBJECTIVE

To determine the immediate and short-term effects of adding cervical spine high-velocity, low-amplitude thrust (HVLAT) to behavioral education, soft tissue mobilization, and a home exercise program on pain and dysfunction for people with a primary complaint of temporomandibular disorder (TMD) with myalgia.

DESIGN

Randomized clinical trial.

METHODS

Fifty individuals with TMD were randomly assigned to receive cervical HVLAT or sham manipulation for 4 visits over 4 weeks. Participants in both groups received other treatments, including standardized behavioral education, soft tissue mobilization, and a home exercise program. Primary outcomes included maximal mouth opening, the numeric pain-rating scale, the Jaw Functional Limitation Scale (JFLS), the Tampa Scale of Kinesiophobia for TMD (TSK-TMD), and a global rating of change (GROC). Self-report and objective measurements were taken at baseline, immediately after initial treatment, and follow-ups of 1 week and 4 weeks. A 2-by-4 mixed-model analysis of variance was used, with intervention group as the between-subjects factor and time as the within-subject factor. Separate analyses of variance were performed for dependent variables, and the hypothesis of interest was the group-by-time interaction.

RESULTS

There was no significant interaction for maximal mouth opening, the numeric pain-rating scale, or secondary measures. There were significant 2-way interactions for the JFLS (d = 0.60) and TSK-TMD (d = 0.80). The HVLAT group had lower fear at 4 weeks and improved jaw function earlier (1 week). The GROC favored the HVLAT group, with significant differences in successful outcomes noted immediately after baseline treatment (thrust, 6/25; sham, 0/25) and at 4 weeks (thrust, 17/25; sham, 10/25).

CONCLUSION

Both groups improved over time; however, differences between groups were small. There were significant differences between groups for the JFLS, TSK-TMD, and GROC. The additive clinical effect of cervical HVLAT to standard care remains unclear for treating TMD. J Orthop Sports Phys Ther 2020;50(8):455-465. Epub 6 Jan 2020. doi:10.2519/jospt.2020.9175.

Short-term effects of spinal thrust joint manipulation on postural sway in patients with chronic mechanical neck pain: a randomized controlled trial

PURPOSE

Our aim was to compare the efficacy of spinal manipulation of the upper cervical spine (C1-C2) on postural sway in patients with chronic mechanical neck pain with the application of a combination of cervical (C3-C4), cervicothoracic (C7-T1) and thoracic spine (T5-T6) thrust joint manipulation.

METHODS

One hundred eighty-six (n = 186) individuals with chronic mechanical neck pain were randomised to receive an upper cervical spine manipulation (n = 93) or three different spinal manipulation techniques applied to the cervical spine, cervicothoracic joint and thoracic spine (n = 93). Measures included the assessment of stabilometric parameters using the Medicapteurs S-Plate platform. Secondarily, neck pain was analysed using the Numeric Pain Rating Scale.

RESULTS

We observe a decrease in the length of the centre of pressure path, average speed, medio-lateral and antero-posterior displacement with statistically significant results (p < 0.05) in the upper cervical manipulation group. Both interventions are equally effective in reducing neck pain after fifteen days (p < 0.001).

CONCLUSION

The application of upper cervical thrust joint manipulation is more effective in improving stabilometric parameters in patients with chronic mechanical neck pain. Trial registration: The study was registered in the Australian and New Zealand Clinical Trial Registry (no. ACTRN12619000546156).Implications for rehabilitationPatients who suffer from neck pain exhibit increased postural sway than asymptomatic subjects.Both spinal manipulation treatments applied in this study are equally effective in reducing neck pain.Spinal manipulation treatment on the upper cervical spine improves postural stability parameters.

Spinal manipulation for the management of cervicogenic headache: A systematic review and meta-analysis

BACKGROUND

Spinal manipulative therapy (SMT) is frequently used to manage cervicogenic headache (CGHA). No meta-analysis has investigated the effectiveness of SMT exclusively for CGHA.

OBJECTIVE

To evaluate the effectiveness of SMT for CGHA.

DATABASES AND DATA TREATMENT

Five databases identified randomized controlled trials comparing SMT with other manual therapies. The PEDro scale assessed the risk-of-bias. Pain and disability data were extracted and converted to a common scale. A random effects model was used for several follow-up periods. GRADE described the quality of evidence.

RESULTS

Seven trials were eligible. At short-term follow-up, there was a significant, small effect favouring SMT for pain intensity (mean difference [MD] -10.88 [95% CI, -17.94, -3.82]) and small effects for pain frequency (standardized mean difference [SMD] -0.35 [95% CI, -0.66, -0.04]). There was no effect for pain duration (SMD - 0.08 [95% CI, -0.47, 0.32]). There was a significant, small effect favouring SMT for disability (MD - 13.31 [95% CI, -18.07, -8.56]). At intermediate follow-up, there was no significant effects for pain intensity (MD - 9.77 [-24.21 to 4.68]) and a significant, small effect favouring SMT for pain frequency (SMD - 0.32 [-0.63 to - 0.00]). At long-term follow-up, there was no significant effects for pain intensity (MD - 0.76 [-5.89 to 4.37]) and for pain frequency (SMD - 0.37 [-0.84 to 0.10]).

CONCLUSION

For CGHA, SMT provides small, superior short-term benefits for pain intensity, frequency and disability, but not pain duration, however, high-quality evidence in this field is lacking. The long-term impact is not significant.

SIGNIFICANCE

CGHA are a common headache disorder. SMT can be considered an effective treatment modality, with this review suggesting it providing superior, small, short-term effects for pain intensity, frequency and disability when compared with other manual therapies. These findings may help clinicians in practice better understand the treatment effects of SMT alone for CGHA.

Reaction Force Magnitude and Orientation During Supine Thoracic Spine Thrust Manipulation: An Exploratory Analysis and Reliability of Preload and Impulse Phase

OBJECTIVE

The main purpose of this study was to explore specific kinetic parameters during supine thoracic thrust manipulation and to analyze task reliability and differences between various practitioners METHODS: Kinetic parameters were assessed by examining ground reaction force magnitude and orientation (on the basis of the zenithal angle) using force platforms. The manipulative procedure (consisting of the application of 3 preloads followed by 1 single thrust adjustment) was performed by different practitioners at 3 sessions. Application of thrust was allowed for trained practitioners only. Preload force, peak force, and vector force orientation were compared between sessions and practitioners.

RESULTS

Reliability analysis showed that practitioners achieved similar preload and peak force independent of the session, with comparable force orientation data. Differences between practitioners were observed for preload and peak force but not regarding the zenithal angle during the thrust phase.

CONCLUSION

This study is the first that explores kinetic parameters for supine thoracic thrust manipulation. Task repeatability was confirmed and several differences were observed between practitioners. Certainly, there is a need for further investigation examining both dynamic parameters (ie, velocity and accelerations) and the potential neurologic effect of such manipulative technique.
