Intertester Reliability and Diagnostic Validity of the Cervical Flexion-Rotation Test

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.

Profiling migraine patients according to clinical and psychophysical characteristics: clinical validity of distinct migraine clusters

AIMS

Investigate if different clinical and psychophysical bedside tools can differentiate between district migraine phenotypes in ictal/perictal (cohort 1) and interictal (cohort 2) phases.

METHOD

This observational study included two independent samples in which patients were subgrouped into distinct clusters using standardized bedside assessment tools (headache frequency, disability, cervical active range of motion, pressure pain threshold in different areas): (A) cohort 1-ictal/perictal migraine patients were subgrouped, based on previous studies, into two clusters, i.e., Cluster-1.1 No Psychophysical Impairments (NPI) and Cluster-1.2 Increased Pain Sensitivity and Cervical Musculoskeletal Dysfunction (IPS-CMD); (B) cohort 2-interictal migraine patients were subgrouped into three clusters, i.e., Cluster-2.1 NPI, Cluster-2.2 IPS, and Cluster-2.3 IPS-CMD. Clinical characteristics (multiple questionnaires), somatosensory function (comprehensive quantitative sensory testing (QST)), and cervical musculoskeletal impairments (cervical musculoskeletal assessment) were assessed and compared across headache clusters and a group of 56 healthy controls matched for sex and age.

RESULTS

Cohort 1: A total of 156 subjects were included. Cluster-1.2 (IPS-CMD) had higher headache intensity (p = 0.048), worse headache-related (p = 0.003) and neck-related disability (p = 0.005), worse quality of life (p = 0.003), and higher symptoms related to sensitization (p = 0.001) and psychological burden (p = 0.005) vs. Cluster-1.1(NPI). Furthermore, Cluster-1.2 (IPS-CMD) had (1) reduced cervical active and passive range of motion (p < 0.023), reduced functionality of deep cervical flexors (p < 0.001), and reduced values in all QST(p < 0.001) vs. controls, and (2) reduced active mobility in flexion, left/right lateral flexion (p < 0.045), and reduced values in QST (p < 0.001) vs. Cluster-1.1 (NPI). Cohort 2: A total of 154 subjects were included. Cluster-2.3 (IPS-CMD) had (1) longer disease duration (p = 0.006), higher headache frequency (p = 0.006), disability (p < 0.001), and psychological burden (p = 0.027) vs. Cluster-2.2 (IPS) and (2) higher headache-related disability (p = 0.010), neck-related disability (p = 0.009), and higher symptoms of sensitization (p = 0.018) vs. Cluster-2.1 (NPI). Cluster-2.3(IPS-CMD) had reduced cervical active and passive range of motion (p < 0.034), and reduced functionality of deep cervical flexors (p < 0.001), vs. controls, Custer-2.1 (NPI), and Cluster-2.2 (IPS). Cluster-2.2 (IPS) and 2.3 (IPS-CMD) had reduced QST values vs. controls (p < 0.001) and Cluster-2.1 (p < 0.039).

CONCLUSION

A battery of patient-related outcome measures (PROMs) and quantitative bedside tools can separate migraine clusters with different clinical characteristics, somatosensory functions, and cervical musculoskeletal impairments. This confirms the existence of distinct migraine phenotypes and emphasizes the importance of migraine phases of which the characteristics are assessed. This may have implications for responders and non-responders to anti-migraine medications.

Cervicogenic headache - How to recognize and treat

Cervicogenic headache, described almost 100 years ago, only had its clinical awakening at the end of the century with the work of Professor Sjaastad. Its classic definition is the induction of trigeminal symptoms from cervical disorders, thanks to trigeminocervical convergence mechanisms. For this reason, it can manifest several features typical of migraine, leading to diagnostic errors. Classically, subjects complain of fixed unilateral headaches, with cervical onset and trigeminal irradiation, associated with reduced neck mobility and flexion strength. The headache is mild to moderate, described as pulsatile or compressive, accompanied by nausea, vomiting, photophobia, phonophobia, and may present autonomic symptoms and dizziness. The pain duration varies from one day to weeks, and its frequency is unpredictable. A history of whiplash injury is common. The differential diagnosis encompasses migraine and tension-type headache. Management includes physiotherapy rehabilitation, anesthetic blocks, and selectively surgical procedures. In this article, all these aspects were extensively covered.

Immediate effects of superficial dry needling of the trigeminal nerve innervation field for participants with cervicogenic headache. A randomized controlled trial

BACKGROUND

Cervicogenic headache (CGH) is a common condition with a neuroanatomical basis involving the trigeminal nerve. Dry needling (DN) is a safe and effective treatment for CGH but most studies involve deep DN to cervical musculature.

OBJECTIVE

The aim of this study was to investigate immediate effects of superficial DN of the trigeminal nerve innervation field on numeric pain rating scale (NPRS), flexion-rotation test (FRT), cervical range of motion (AROM), and pain-pressure threshold (PPT) of right (R) and left (L) supraorbital (SO), and right (R) and left (L) greater occipital (GO) nerves in participants with CGH.

METHODS

A parallel controlled randomized design involving 30 participants with CGH received either superficial DN (N = 17) or sham DN (N = 13). Participants and outcome assessors were blind to group assignment. Wilcoxon signed rank analyzed within-group effects and Mann-Whitney U analyzed between-group.

RESULTS

Statistically significant between-group differences were observed for NPRS (P < .001) and AROM (P < .006) favoring DN and were clinically meaningful. Right and left Flexion rotation tests (FRT) outcomes were non-significant (P = .137) but clinically meaningful. No differences were observed for PPT over: R SO (P = .187); L SO (P = .052); R GO (P = .187); or L GO (P = .052). Between-group effect sizes across variables were moderate to large (0.53-1.4) but confidence intervals were wide.

CONCLUSION

Superficial DN targeting the innervation field of the trigeminal nerve improves clinical outcomes in patients with CGH. Only the immediate effects were analyzed and the sample size was small. Larger, longer-term assessments are needed comparing superficial DN of the trigeminal innervation field and other conservative interventions for CGH.

Is device guided training targeted to the craniocervical flexor and extensor muscles efficacious? A preliminary randomized controlled trial in a cervicogenic headache population

BACKGROUND

Specific neck exercise is effective in the management of cervicogenic headache (CH). The Spinertial device was designed to facilitate craniocervical flexion and extension training, but its efficacy, judged on change in headache impact, has not been tested.

OBJECTIVE

To compare guided and progressive resisted specific neck exercise targeted to the craniocervical flexors and extensors (SNE-fe) performed with Spinertial device to progressive SNE-fe without the device in a cohort with CH.

DESIGN

Randomised controlled trial.

METHODS

Twenty-eight participants with CH were randomly allocated to the Spinertial group (SG) or SNE-fe exercise group without the device (EG). Both groups performed 12 sessions of SNE-fe over six-weeks. The primary outcome was headache impact (HIT-6). Secondary outcomes were the craniocervical flexion test (CCFT), upper cervical (UCS) and lower cervical range of movement, flexion rotation test (FRT) analysed as more or less restricted side (MRS, LRS), the self-reported global rating of change (GROC-scale) and satisfaction with the exercise program (PACES). Outcomes were measured at baseline, post-intervention (T1) and after 1-month (T2).

RESULTS

Significant between-groups differences were found favouring the SG for HIT-6 (T1 p = 0.010, d = 0.5; T2 p < 0.004, d = 0.4), CCFT, UCS ROM, FRT MRS, FRT LRS, PACES and GROC-scale (T1: all p < 0.01; T2: all p < 0.01). Effects sizes were large (>0.8) at T1 and T2. No between-groups differences were found for lower cervical ROM.

CONCLUSION

Training with the Spinertial was more effective than SNE without the device for improving the impact of headache, the endurance of deep neck flexors and UCS ROM in participants with CH.

Utilizing directional preference in the management of cervicogenic headache: a case series

BACKGROUND/PURPOSE

Headaches are among the most common complaints requiring medical care, and annual expenditures for this condition are estimated to be 14 billion US dollars. The International Headache Society (IHS) describes cervicogenic headache (CGH) as a secondary type of headache emanating from the cervical spine which may be referred to one or more regions of the head and/or face. Mechanical Diagnosis and Therapy (MDT) is an approach shown to be effective in the management of spinal musculoskeletal disorders; however, there is limited evidence as to its efficacy in the management of CGH. The purpose of this case series was to examine the MDT approach in the assessment, classification, and management of a sample of patients experiencing cervicogenic headache.

CASE DESCRIPTION

This study was a prospective case series. Following IRB approval, 15 patients meeting the study inclusion criteria were recruited from a hospital-based outpatient physical therapy clinic. All subjects received a physical therapy examination by a Diploma trained MDT clinician which included but was not limited to patient self-report forms and the testing of repeated end range movements. The Numerical Pain Rating Scale (NPRS), Neck Disability Index (NDI), Headache Disability Index (HDI), Yellow Flag Risk Form (YFRF), Cervical Flexion Rotation Test (CFRT), and the Craniocervical Flexion Test (CCFT) were administered at the initial visit, 5th visit, and 10th visit or discharge, whichever occurred first. The NPRS, NDI, and HDI were re-administered at a 3 month follow up. Following the initial examination, patients were classified into the MDT categories of derangement, dysfunction, postural, or 'other' and then received intervention based on directional preference.

OUTCOMES

Fifteen subjects (mean age, 45.9 years; F = 11, M = 4; symptom duration, 44.3 months; average visits, 8.8) received an examination and intervention and completed follow-up outcome measures. Based on MDT classification criteria, all 15 subjects in this case series were classified as derangements. A non-parametric Friedman test of Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation differences among repeated measures was conducted on all outcome measures revealing statistically significant improvements in NPRS (p < .01), NDI(p < .01), and HDI (p < .01) scores at visit 10 and 3 month follow up. The mean change scores exceeded the minimal clinical important difference (MCID) for NPRS (4.2), NDI (7.6), and HDI (28.5). CCFT scores improved significantly from the initial examination to visit 5 (p < .01) and YFRF scores improved significantly between visits 5 and 10 (p < .01).

DISCUSSION/CONCLUSION

The diagnosis of CGH is difficult to determine based on pathoanatomical assessment. This case series suggests that the patient's response to repeated end range movements may indicate a directional preference for manual procedures and exercises which may be used in management of musculoskeletal conditions such as CGH.

Cervical musculoskeletal impairments and pain sensitivity in migraine patients

INTRODUCTION

Currently, examination of migraine patients relies on a clinical interview investigating symptoms characteristics. Despite this, to help identify distinct migraine subtypes and allow a personalized treatment approach, biomarkers to profile distinct migraine subtypes should be utilized in clinical and research settings. Therefore, there is a need to include physical and psychophysical examinations aimed at assessing migraine features quantitatively.

PURPOSE

This paper aimed to discuss if increased pressure pain sensitivity and impaired cervical musculoskeletal function could be considered 1) as quantitative features of migraine and 2) if they could be used as biomarkers to profile migraine patients in distinct subtypes.

IMPLICATION

Increased pain sensitivity and cervical musculoskeletal impairments have been suggested as quantitative biomarkers to phenotype and subgroup migraine patients in clinical and research settings. This could provide the first step for a mechanistically-driven and personalized treatment approach according to migraine phenotypes.

Cervical musculoskeletal impairments and pressure pain sensitivity in office workers with headache

BACKGROUND

Office workers are specifically vulnerable to headache conditions. Neck pain is reported by almost 80% of patients with headaches. Associations between currently recommended tests to examine cervical musculoskeletal impairments, pressure pain sensitivity and self-reported variables in headache, are unknown. The aim of this study is to evaluate whether cervical musculoskeletal impairments and pressure pain sensitivity are associated with self-reported headache variables in office workers.

METHODS

This study reports a cross-sectional analysis using baseline data of a randomized controlled trial. Office workers with headache were included in this analysis. Multivariate associations, controlled for age, sex and neck pain, between cervical musculoskeletal variables (strength, endurance, range of motion, movement control) and pressure pain threshold (PPT) over the neck and self-reported headache variables, such as frequency, intensity, and the Headache-Impact-Test-6, were examined.

RESULTS

Eighty-eight office workers with a 4-week headache frequency of 4.8 (±5.1) days, a moderate average headache intensity (4.5 ± 2.1 on the NRS), and "some impact" (mean score: 53.7 ± 7.9) on the headache-impact-test-6, were included. Range of motion and PPT tested over the upper cervical spine were found to be most consistently associated with any headache variable. An adjusted R2 of 0.26 was found to explain headache intensity and the score on the Headache-Impact-Test-6 by several cervical musculoskeletal and PPT variables.

DISCUSSION

Cervical musculoskeletal impairments can explain, irrespective of coexisting neck pain, only little variability of the presence of headache in office workers. Neck pain is likely a symptom of the headache condition, and not a separate entity.

Migraine patients with and without neck pain: Differences in clinical characteristics, sensitization, musculoskeletal impairments, and psychological burden

AIMS

This study aims to assess differences in clinical characteristics across healthy controls and migraine patients with (MNP) and without (MwoNP) neck pain.

METHOD

This study assessed: headache frequency; headache disability index (HDI); central sensitization inventory (CSI); Hospital Anxiety (HADS-A) and Depression (HADS-D) scale; active range of motion (AROM); flexion rotation test (FRT); activation pressure score (APS); number of active/latent myofascial trigger points (MTrPs) in head/neck muscles; number of positive cervical vertebral segments (C1/C2) who reproduce migraine pain; wind-up ratio (WUR); mechanical pain threshold (MPT) and static pressure pain threshold (sPPT) over the trigeminal area; sPPT and dynamic PPT (dPPT) over the cervical area; sPPTs and MPT over the hand.

RESULTS

Compared to controls, MNP had: worse CSI, HADS-A, and HADS-D (all, p < 0.002); reduced AROM (flexion, extension, left lateral-flexion, and right-rotation), FRT, APS, and a higher number of MTrPs and positive cervical vertebral segments (all, p < 0.020); reduced trigeminal MPT and sPPT, cervical sPPT and dPPT, hand MPT and sPPT (all, p < 0.006). Compared to controls, MwoNP had: worse CSI, and HADS-A (all, p < 0.002); reduced AROM (flexion, and left lateral-flexion), FRT, APS, and a higher number of MTrPs and positive cervical vertebral segments (all, p < 0.017); reduced trigeminal MPT and cervical dPPT (all, p < 0.007). Compared to MwoNP, MNP had higher headache frequency, worse HDI and CSI (all, p < 0.006); reduced AROM (flexion, and right rotation) (all, p < 0.037); reduced cervical dPPT (all, p < 0.002).

CONCLUSION

MNP had worse headache characteristics, more pronounced cervical musculoskeletal impairments, enhanced signs and symptoms related to sensitization, and worse psychological burden compared to MwoNP.

Headache and orofacial pain: A traffic-light prognosis-based management approach for the musculoskeletal practice

Introduction

Headache (HA) is one of the most prevalent disabling conditions worldwide and is classified as either primary or secondary. Orofacial pain (OFP) is a frequent pain perceived in the face and/or the oral cavity and is generally distinct from a headache, according to anatomical definitions. Based on the up-to-date classification of the International Headache Society, out of more than 300 specific types of HA only two are directly attributed to the musculoskeletal system: The cervicogenic HA and HA attributed to temporomandibular disorders. Because patients with HA and/or OFP frequently seek help in the musculoskeletal practice, a clear and tailored prognosis-based classification system is required to achieve better clinical outcomes.

Purpose

The aim of perspective article is to suggest a practical traffic-light prognosis-based classification system to improve the management of patients with HA and/or OFP in the musculoskeletal practice. This classification system is based on the best available scientific knowledge based on the unique set-up and clinical reasoning process of musculoskeletal practitioners.

Implications

Implementation of this traffic-light classification system will improve clinical outcomes by helping practitioners invest their time in treating patients with significant involvement of the musculoskeletal system in their clinical presentation and avoid treating patients that are not likely to respond to a musculoskeletal based intervention. Furthermore, this framework incorporates medical screening for dangerous medical conditions, and profiling the psychosocial aspects of each patient; thus follows the biopsychosocial rehabilitation paradigm.

Are there differences between a real C0-C1 mobilization and a sham technique in function and pressure pain threshold in patients with chronic neck pain and upper cervical restriction? A randomised controlled clinical trial

BACKGROUND

Chronic neck pain is one of the main reasons for visiting a healthcare professional. In recent years, it has been shown that upper cervical restriction may be a factor involved in neck pain.

OBJECTIVE

To compare the immediate effects of a real cervical mobilization technique versus a sham cervical mobilization technique in patients with chronic neck pain and upper cervical restriction.

METHODS

This was a randomised, controlled, double-blind clinical trial. Twenty-eight patients with chronic neck pain were recruited and divided into two groups (14 = real cervical mobilization; 14 = sham mobilization). Both groups received a single 5-minute treatment session. Upper cervical range motion, flexion-rotation test, deep cervical activation and pressure pain threshold were measured.

RESULTS

In the between-groups comparison, statistically significant differences were found in favour of the real cervical mobilization group in upper cervical extension (p= 0.003), more restricted side of flexion-rotation test (p< 0.001) and less restricted side of flexion-rotation test (p= 0.007) and in the pressure pain threshold of the right trapezius (p= 0.040) and right splenius (p= 0.049). No differences in deep muscle activation were obtained.

CONCLUSION

The real cervical mobilization group generates improvements in upper cervical spine movement and pressure pain threshold of right trapezius and right splenius compared to the sham group in patients with chronic neck pain and upper cervical restriction.

Association between age, sex and cervical and upper cervical rotation tests. Descriptive and correlational study in healthy volunteers

Background

Active cervical spine rotation (ACROM Rot) shows cervical rotation and flexion rotation test (FRT); side-bending rotation test (SBRT) and upper cervical axial rotation test (C0-C2ART) are described to measure upper cervical rotation. The objectives of this study are (1) to describe the normal range of motion (ROM) of ACROM Rot, and the ROM in FRT, SBRT and C0-C2ART tests; (2) to explore the correlation among the four tests and (3) to investigate the influence of age and sex in their ROM.

Methods

A cross-sectional study was carried out with healthy volunteers from 18 to 75 years of age. Tests were measured using a CROM device and a bubble inclinometer. Descriptive analysis was performed to establish normative data for the ROM tests. Correlation analysis was conducted to understand the relation between upper and global cervical rotation ROM and among the three upper cervical rotation tests. Linear regression models were developed to understand the influence of age and sex in the ROM of all tests.

Results

Normative values were obtained from 122 healthy volunteers (50% male), by sex and age strata. The degree of correlation ranged between 0.582 (p < 0.01) for FRT and ACROM Rot left and 0.217 (p < 0.05) for SBRT and C0-C2ART left. Linear regression models showed the influence of sex for ACROM Rot right (men -4.64° less than women), SBRT (men -4.1° less than women) left and C0-C2ART right and left (men -2.24° and -1.78° less than women). The age influenced rotation ROM with a decrease for every 10 years of -2.11° and -1.96° for ACROM Rot right and left, of -1.72° and -1.26° for FRT right and left and -0.58° and -0.41° for C0-C2ART right and left in the linear regression models. No association was found between age and SBRT (p = 0.63 for right SBRT and p = 0.49 for left SBRT).

Conclusion

Weak-to-moderate correlation was found between the upper cervical spine rotation tests and with the ACROM. Women had a larger ROM in ACROM Rot right, SBRT left and C0-C2ART. Decreases in ROM related with age were observed for ACROM Rot, FRT and C0-C2ART but not for SBRT.

Assessment of atlantoaxial rotation: how accurate is clinical measurement? a comparative study of cervical range of motion using MRI and standard orthopedic techniques

PURPOSE

Measurement of neck rotation is currently reliant on radiologic imaging. Given the radiation exposure for CT imaging and the additional inconvenience for the patients, an alternative assessment is needed. Goniometers are comfortably to use and easy to access, also for private consulting. The aim of this study was the assessment of whether a handheld goniometer can be used for accurately measuring the rotation of C1-C2.

METHODS

Clinical measurement of rotation was taken in flexed position of the neck. As comparison functional MRI was used. The measured rotation of C1-C2 was compared to identify the accuracy of the goniometer, in comparison to functional MRI scan.

RESULTS

Analysis of accuracy using a goniometer and dynamic MRI to assess C1-2 axial rotation showed significant differences for absolute values, but not regarding the percentage of rotation compared to total neck rotation.

CONCLUSION

The goniometer is exact to impartially determine the percentage contribution of C1-2 rotation to total neck rotation.

Sports-related concussion: assessing the comprehension, collaboration, and contribution of chiropractors

Over the last 2 decades, sports-related concussion (SRC) awareness and management have evolved from an emphasis on complete cognitive and physical rest to evidence-based protocols and interventions. Chiropractors are primary care providers with exposure to athletes and teams in collision sports and, in addition, manage patients with concussion-like symptoms including neck pain, dizziness, and headache. With SRC frequently occurring in the absence of a medical practitioner, the role of allied health practitioners like chiropractors should be emphasised when it comes to the recognition, assessment, and management of SRC. This commentary discusses the potential contribution of chiropractors in SRC and the specific role their expertise in the cervical spine may play in symptom evaluation and management. A PubMed and Google scholar review of the chiropractic SRC literature suggests that the chiropractic profession appears under-represented in concussion research in athletic populations compared to other medical and allied health fields. This includes an absence of chiropractic clinicians with a focus on SRC participating in the Concussion in Sport Group (CISG) and the International Consensus Conferences on Concussion. Furthermore, with evolving evidence suggesting the importance of cervicogenic manifestations in SRC, there is an opportunity for chiropractors to participate in SRC diagnosis and management more fully and contribute scientifically to an area of specialised knowledge and training. With a dearth of chiropractic orientated SRC science, clinical SRC expertise, and clinical chiropractic representation in the CISG; it is incumbent on chiropractic clinicians and scientists to take up this opportunity through meaningful contribution and involvement in the SRC field.

Cervicogenic headache, an easy diagnosis? A systematic review and meta-analysis of diagnostic studies

BACKGROUND

The diagnosis of cervicogenic headache (CGH) remains a challenge for clinicians as the diagnostic value of detailed history and clinical findings remains unclear.

OBJECTIVES

To update and evaluate available evidence of the prevalence and the diagnostic accuracy of the detailed history and clinical findings for CGH in adults with headache.

DESIGN

Systematic review with meta-analysis.

METHODS

CINAHL, Cochrane Central, Embase, PEDro and PubMed were searched for studies before March 2022 that reported detailed history and/or clinical findings related to the diagnosis of cervicogenic headache. Study selection, risk of bias assessment (QUADAS-2 and PROBAST), and data extraction were performed. Meta-analyses for the cervical flexion-rotation test (CFRT) was performed. Certainty of the evidence was assessed with the GRADE approach.

RESULTS

Eleven studies were included. Moderate certainty evidence indicated that the CFRT differentiated CGH from lower cervical facet-induced headache, migraine, concomitant headaches or asymptomatic subjects (Se 83.0% [95%CI:70.0%-92.0%]; Sp 83.0% [95%CI:71.0%-91.0%]; positive LR 5.0 [95%CI:2.6-9.5]; negative LR 0.2 [95%CI:0.1-0.4]; n = 4 studies; n = 182 participants). Several diagnostic classifications and test clusters based on headache history and clinical findings can be useful, despite uncertain accuracy, in formulating the diagnosis of CGH.

CONCLUSION

Evidence support to undertake an evaluation of headache history and signs and symptoms and a physical examination of the patient neck to diagnose CGH. During the physical examination, a positive or negative CFRT probably has a small to moderate effect on the probability of a patient having a CGH. The diagnostic value of the other findings remains unclear.

Flexion-rotation test and C0-C2 axial rotation test. Are they equally reliable for novice clinicians?

OBJECTIVE

To analyse the inter- and intra-examiner reliability for the neck flexion-rotation test and the C0-C2 axial rotation test when applied in asymptomatic subjects by two novice physiotherapists.

DESIGN

Repeated measures reliability study design. The study was approved by the Research Ethics Committee of [X], in compliance with the Declaration of Helsinki (CSEULS-PI: 004/2020).

METHODS

32 asymptomatic adults were included, recruited by convenience sampling. Two sessions were scheduled for each subject, with an intersession break of 30 min. Two inexperienced raters blinded to their own previous and peer results performed three movements to both sides using the flexion-rotation test and the C0-C2 axial rotation test in randomised order of rater, test and direction. A third researcher collected the data measured by inertial sensors and displayed to the Pro Motion Capture software.

RESULTS

Both raters showed good-excellent intra-examiner reliability (ICC_(2,3) ranging from 0.88 to 0.94) and moderate to good inter-examiner reliability (ICC_(2,3) ranging from 0.58 to 0.86) to measure the rotation ROM with the FRT. The C0-C2 axial rotation test resulted in poor to moderate intra-examiner reliability (ICC_(2,3) ranging from 0.33 to 0.74) and poor inter-examiner reliability using (ICC_(2,3) ranging from 0.16 to 0.37).

CONCLUSION

Although performed by novice raters, the FRT showed good to excellent intra and inter-examiner reliability. Results for the C0-C2 axial rotation test were less reliable. We suggest that novice physiotherapists use the FRT instead of the C0-C2 axial rotation test in order to determine C1-C2 dysfunction.

Reproduction and resolution of familiar head pain with upper cervical spine sustained joint mobilization may help identify cervicogenic headaches: a case-control study

BACKGROUND

The relative value of clinical tests toward identifying cervicogenic headache (CGH) remains under investigated. Whilst certain physical examination findings have been associated with CGH, consensus on which findings provide the strongest association remains elusive.

OBJECTIVES

To determine which cervical musculoskeletal assessment procedures used in CGH are positively associated with CGH.

DESIGN

Single blind observational study.

METHODS

Four selected musculoskeletal assessment procedures of the cervical spine, craniocervical flexion test, cervical flexion-rotation test, cervical retraction range of motion and reproduction and resolution of familiar head pain with upper cervical spine sustained joint mobilization, were applied to 20 headache and 20 controls. Inclusion criteria for the headache group met the International Headache Society criteria for CGH except positive diagnostic blocks.

RESULTS

Upper cervical spine sustained joint mobilization testing associated with reproduction and resolution of familiar head pain was strongly associated with CGH (Odds Ratio = 36, p < 0.01). This was 78% sensitive and 90% specific in identifying CGH. Other physical tests were not statistically associated with CGH.

CONCLUSIONS

Reproduction and resolution of familiar head pain with upper cervical spine sustained joint mobilization is effective in differentiating those with CGH from control participants. Other cervical measures did not clearly identify CGH in this study.

Combination of Two Manipulative Techniques for the Treatment of Cervicogenic Dizziness: A Randomized Controlled Trial

Cervicogenic dizziness is clinically associated with upper cervical spine dysfunctions. It seems that manual therapy decreases the intensity of dizziness in these subjects, but what happens to pain measured by pressure pain threshold (PPT) has not been studied. Purpose: analyze the short-term effects of combination two manipulation techniques protocol in worst dizziness intensity (wVAS), dizziness and cervical disability, upper cervical spine mobility and mechanosensivity of cervical tissue. Methods: Assessor-blinded randomized controlled trial was developed. A total of 40 patients with cervicogenic dizziness were randomly divided into two groups. The experimental group received three treatments consisting of a functional massage and a manipulation technique, and compared with a control group. The wVAS, dizziness handicap inventory (DHI), neck disability index (NDI), UCS mobility, and PPTs were measured. Measurements were made at the baseline, first follow-up 48 h after intervention and second follow-up 1 month after the intervention. Results: at second follow-up wVAS (p < 0.001), NDI (p < 0.001), DHI (p < 0.001), and upper right trapezius (p < 0.022) and right suboccipital (p < 0.043) PPTs showed a difference between groups in favor of the experimental group. Conclusions: apparently, the proposed intervention protocol decreases the intensity of dizziness and the mechanosensitivity of the cervical tissue and improves the feeling of disability due to neck pain and dizziness.

Alterations in kinematics of temporomandibular joint associated with chronic neck pain

BACKGROUND

Temporomandibular disorder (TMD) is an umbrella term for pain and dysfunction of the temporomandibular joint (TMJ) and its associated structures. Patients with TMD show changes in TMJ kinematics and masticatory muscle activation. TMD is commonly comorbid with non-specific chronic neck pain (NCNP), which may be one of the risk factors for TMD.

OBJECTIVES

This study aimed to investigate whether patients with NCNP have altered TMJ kinematics and masticatory muscle activity.

METHODS

This was a cross-sectional exploratory study including 19 healthy participants and 20 patients with NCNP but without TMD symptoms. TMJ kinematics was measured during mouth opening and closing, jaw protrusion and jaw lateral deviation. Surface electromyography was used to record the muscle activity of the anterior temporalis, masseter, sternocleidomastoid and upper trapezius while clenching. Furthermore, cervical posture, cervical range of motion (ROM) and pressure-pain threshold of the neck and masticatory muscles were measured.

RESULTS

Compared with the healthy group, the NCNP group showed significantly reduced upper cervical rotation ROM (p = .041) and increased condylar path length (p = .02), condylar translation (opening p = .034, closing p = .011) and mechanical pain sensitivity of the upper trapezius (p = .018). Increased condylar translation was significantly correlated with reduced upper cervical mobility and poor cervical posture (r = -0.322 to -0.397; p = .012-.046).

CONCLUSION

Increased condylar translation and path length in patients with NCNP may indicate poor control of TMJ articular movement, which may result from neck pain or may be a compensation for limited neck mobility. Evaluation of excessive TMJ translation may be considered in patients with NCNP.

Cervical musculoskeletal impairments in the 4 phases of the migraine cycle in episodic migraine patients

OBJECTIVE

To assess cervical musculoskeletal impairments during the 4 phases of a migraine cycle in episodic migraine patients, controlling for the presence of concomitant neck pain.

METHODS

Differences in cervical musculoskeletal impairments were assessed during the 4 migraine phases in episodic migraine patients and compared with healthy controls controlling for concomitant neck pain. Cervical musculoskeletal impairments were assessed as follow: cervical active range of motion; flexion rotation test; craniocervical flexion test and calculation of activation pressure score; the total number of myofascial trigger points in head/neck muscles; the number of positivevertebral segments (headache's reproduction) during passive accessory intervertebral movement; pressure pain thresholds over C1, C2, C4, C6 vertebral segments bilaterally, trigeminal area, hand, and leg. Signs of pain sensitization were assessed by evaluating mechanical pain threshold over trigeminal area and hand, pressure pain thresholds, and the wind-up ratio. The Bonferroni-corrected p-value (05/4 = 0.013) was adopted to assess the difference between groups, while a p-value of 0.05 was considered significant for the correlation analysis.

RESULTS

A total of 159 patients and 52 controls were included. Flexion rotation test and craniocervical flexion test were reduced in all 4 phases of the migraine cycle versus healthy controls (p < 0.001). The number of myofascial trigger points and positive vertebral segments was increased in all 4 phases of the migraine cycle versus healthy controls (p < 0.001). Flexion, extension, and total cervical active range of motion and cervical pressure pain thresholds were reduced in episodic migraine in the ictal phase versus controls (p < 0.007) with no other significant differences. Outside the ictal phase, the total cervical active range of motion was positively correlated with trigeminal and leg pressure pain threshold (p < 0.026), the number of active myofascial trigger points and positive positive vertebral segments were positively correlated with higher headache frequency (p=0.045), longer headache duration (p < 0.008), and with headache-related disability (p = 0.031). Cervical pressure pain thresholds were positively correlated with trigeminal, hand, and leg pressure pain threshold (p < 0.001), and trigeminal and leg mechanical pain thresholds (p < 0.005), and negatively correlated with the wind-up ratio (p < 0.004).

CONCLUSION

In all phases of the migraine cycle, independent of the presence of concomitant neck pain, episodic migraine patients showed reduced flexion rotation test and craniocervical flexion test and an increased number of myofascial trigger points and passive accessory vertebral segments. These impairments are correlated with enhanced headache duration, headache-related disability, and signs of widespread pain sensitization. Reduction in active cervical movement and increased mechanical hyperalgesia of the cervical was consistent in ictal episodic migraine patients and the subgroups of episodic migraine patients with more pronounced widespread sensitization.

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

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

Response rate and comparison of clinical features associated with positive or negative responses to a scapular positioning test in patients with neck pain and altered scapular alignment: a cross-sectional study

Objective

To investigate the frequency and clinical aspects of patients with neck pain who responded and did not respond to scapular repositioning and to determine the clinical features associated with a positive response.

Design

Cross-sectional study.

Setting

Research unit, Department of Physical Therapy, Chiang Mai University.

Participants

Volunteers with non-specific neck pain aged 18–59 years were recruited between May 2020 and February 2021 from hospitals, clinics, university and community.

Outcome measures

Clinical data documented were neck pain (intensity, duration and disability), the presence of headache, type of scapular dysfunction, cervical musculoskeletal impairment (range of motion (ROM), flexion rotation test (FRT) and location of any symptomatic cervical joint dysfunction), upper limb functional limitation and self-reported disability. Manual scapular repositioning was performed on the side of neck pain. Participants were categorised as responsive or non-responsive based on a change in pain and/or cervical rotation range.

Results

A total of 219 people with neck pain responded to advertisements, of which 144 were eligible. Of the eligible participants, 107 (74.3%) demonstrated a clinically relevant improvement in either neck pain or rotation range or both following the scapular repositioning and 37 (25.7%) had no relevant improvement. The responsive group had a high incidence of scapular downward rotation, greater neck pain intensity, headache and cervical musculoskeletal impairment (reduced ROM, positive FRT and symptomatic C1-3 dysfunction) compared with the non-responsive group (p<0.05). A logistic regression model revealed that features strongly associated with a positive response were the presence of headache (Exp(B)=6.0, 95% CI 2.3 to 15.8), scapular downward rotation (Exp(B)=5.3, 95% CI 2.3 to 12.6) and a positive FRT (Exp(B)=4.0, 95% CI 1.5 to 10.6).

Conclusion

Almost 75% of neck pain patients with altered scapular alignment responded to scapular repositioning. The predominance of upper cervical dysfunction with a downwardly rotated scapular in this group suggests a role of poor axioscapular muscle function which might benefit from rehabilitation.

Clinical Assessment of Concussion and Persistent Post-Concussive Symptoms for Neurologists

PURPOSE OF REVIEW

Concussion produces a variety of signs and symptoms. Most patients recover within 2-4 weeks, but a significant minority experiences persistent post-concussive symptoms (PPCS), some of which may be from associated cervical or persistent neurologic sub-system (e.g., vestibular) dysfunction. This review provides evidence-based information for a pertinent history and physical examination of patients with concussion.

RECENT FINDINGS

The differential diagnosis of PPCS is based on the mechanism of injury, a thorough medical history and concussion-pertinent neurological and cervical physical examinations. The concussion physical examination focuses on elements of autonomic function, oculomotor and vestibular function, and the cervical spine. Abnormalities identified on physical examination can inform specific forms of rehabilitation to help speed recovery. Emerging data show that there are specific symptom generators after concussion that can be identified by a thorough history, a pertinent physical examination, and adjunct tests when indicated.

Effects of dry needling of the obliquus capitis inferior on sensorimotor control and cervical mobility in people with neck pain: A double-blind, randomized sham-controlled trial

BACKGROUND

Impairments of sensorimotor control relating to head and eye movement control and postural stability are often present in people with neck pain. The upper cervical spine and particularly the obliquus capitis inferior (OCI) play an important proprioceptive role; and its impairment may alter cervical sensorimotor control. Dry needling (DN) is a valid technique to target the OCI.

OBJECTIVES

To investigate if a single DN session of the OCI muscle improves head and eye movement control-related outcomes, postural stability, and cervical mobility in people with neck pain.

METHODS

Forty people with neck pain were randomly assigned to receive a single session of DN or sham needling of the OCI. Cervical joint position error (JPE), cervical movement sense, standing balance and oculomotor control were examined at baseline, immediately post-intervention, and at one-week follow-up. Active cervical rotation range of motion and the flexion rotation test were used to examine the global and upper cervical rotation mobility, respectively.

RESULTS

Linear mixed-models revealed that the DN group showed a decrease of JPE immediately post-intervention compared to the sham group (mean difference [MD]= -0.93°; 95% confidence interval [CI]: -1.85, -0.02) which was maintained at one-week follow-up (MD= -1.64°; 95%CI: -2.85, -0.43). No effects on standing balance or cervical movement sense were observed in both groups. Upper cervical mobility showed an increase immediately after DN compared to the sham group (MD= 5.14°; 95%CI: 0.77, 9.75) which remained stable at one-week follow-up (MD= 6.98°; 95%CI: 1.31, 12.40). Both group showed an immediate increase in global cervical mobility (MD= -0.14°; 95%CI: -5.29, 4.89).

CONCLUSION

The results from the current study suggest that a single session of DN of the OCI reduces JPE deficits and increases upper cervical mobility in patients with neck pain. Future trials should examine if the addition of this technique to sensorimotor control training add further benefits in the management of neck pain.

Differentiating migraine, cervicogenic headache and asymptomatic individuals based on physical examination findings: a systematic review and meta-analysis

BACKGROUND

Migraine and cervicogenic headache (CGH) are common headache disorders, although the large overlap of symptoms between them makes differential diagnosis challenging. To strengthen differential diagnosis, physical testing has been used to examine for the presence of musculoskeletal impairments in both conditions. This review aimed to systematically evaluate differences in physical examination findings between people with migraine, CGH and asymptomatic individuals.

METHODS

The databases MEDLINE, PubMed, CINAHL, Web of Science, Scopus, EMBASE were searched from inception until January 2020. Risk of bias was assessed with the Downs and Black Scale for non-randomized controlled trials, and with the Quality Assessment of Diagnostic Accuracy Studies tool for diagnostic accuracy studies. When possible, meta-analyses with random effect models was performed.

RESULTS

From 19,682 articles, 62 studies were included in this review and 41 were included in the meta-analyses. The results revealed: a) decreased range of motion [°] (ROM) on the flexion-rotation test (FRT) (17.67, 95%CI:13.69,21.65) and reduced neck flexion strength [N] (23.81, 95%CI:8.78,38.85) in CGH compared to migraine; b) compared to controls, migraineurs exhibit reduced flexion ROM [°] (- 2.85, 95%CI:-5.12,-0.58), lateral flexion ROM [°] (- 2.17, 95% CI:-3.75,-0.59) and FRT [°] (- 8.96, 95%CI:-13.22,-4.69), reduced cervical lordosis angle [°] (- 0.89, 95%CI:-1.72,-0.07), reduced pressure pain thresholds over the cranio-cervical region [kg/cm²], reduced neck extension strength [N] (- 11.13, 95%CI:-16.66,-5.6) and increased activity [%] of the trapezius (6.18, 95%CI:2.65,9.71) and anterior scalene muscles (2.87, 95%CI:0.81,4.94) during performance of the cranio-cervical flexion test; c) compared to controls, CGH patients exhibit decreased neck flexion (- 33.70, 95%CI:-47.23,-20.16) and extension (- 55.78, 95%CI:-77.56,-34.00) strength [N].

CONCLUSION

The FRT and neck flexion strength could support the differential diagnosis of CGH from migraine. Several physical tests were found to differentiate both headache types from asymptomatic individuals. Nevertheless, additional high-quality studies are required to corroborate these findings.

STUDY REGISTRATION

Following indications of Prisma-P guidelines, this protocol was registered in PROSPERO on 21/05/2019 with the number CRD42019135269 . All amendments performed during the review were registered in PROSPERO, indicating the date and what and why was changed.

Effectiveness of Exercise and Manual Therapy as Treatment for Patients with Migraine, Tension-Type Headache or Cervicogenic Headache: An Umbrella and Mapping Review with Meta-Meta-Analysis

The aim of the study was to perform a mapping and umbrella review with meta-meta-analysis (MMA) to synthesise and critically evaluate the effectiveness of manual therapy (MT) and aerobic exercise (AE) in relation to pain intensity, frequency, disability and quality of life in patients with migraines, tension-type headaches (TTH) and cervicogenic headaches (CGH). A systematic search was conducted in PubMed, PEDro, Scielo and Google Scholar up to December 2020. A total of 18 articles met the inclusion criteria, and only 8 were included in the quantitative analysis. The MMA showed results in favour of the interventions in terms of pain intensity and quality of life in migraine, TTH and CCH. Data were also in favour of the intervention in terms of pain frequency in migraine and in terms of disability in TTH. However, there were no significant effects on pain frequency in TTH and CGH. The results showed moderate evidence to suggest that AE reduces pain intensity in patients with migraine. In addition, the evidence in favour of MT or a mixed intervention (including therapeutic exercise) was also moderate in terms of reducing pain intensity in patients with TTH.

The effect of high-intensity physical exertion on measures of cervical spine, vestibular/ocular-motor screening, and vestibulo-ocular reflex function in university level collision and combative sport athletes

OBJECTIVES

To examine how high-intensity physical exertion affects clinical measures of cervical spine (CSp), vestibular/ocular motor screen (VOMS), and vestibulo-ocular reflex (VOR) function.

DESIGN

Case series.

SETTING

Sports Medicine Centre.

PARTICIPANTS

A total of 37 athletes consented to participate (22 rugby, 15 wrestling; 9 men, 28 women; median age = 19 years [range 17-23 years]).

MAIN OUTCOME MEASURES

Outcome measures included tests of CSp (cervical flexor endurance, head perturbation test, cervical flexion rotation test and anterolateral strength), VOR (head thrust test and dynamic visual acuity [DVA]), and a quantified version of the VOMS. These metrics were assessed prior to and after completing the 30-15 Intermittent Fitness Test. Bland-Altman plots and Wilcoxon signed-rank tests were utilized to analyze the data using an alpha of p < 0.004.

RESULTS

Cervical anterolateral strength (kg) was reduced post-exertion on the left (z = 3.87; p < 0.001), but not on the right between conditions (z = -1.49; p = 0.14). Athletes reported increased dizziness (z = -3.55; p = 0.004) and had reduced DVA following exertion (z = -2.78; p < 0.001). All other metrics were not significantly different following exertion (p > 0.011).

CONCLUSION

Reduced performance on DVA, decreased left-anterolateral strength, and increased dizziness occurred following high-intensity exertion in varsity collision and combative athletes, which has implications for sideline screening for sport-related concussion.

Physical therapist guided active intervention of chronic temporomandibular disorder presenting as ear pain: A case report

This case report describes the successful physical therapy management of a 40-year-old female who presented with left ear pain referred from the temporomandibular joint. Diagnosis was primarily based on clinical examination findings and ruling out of red flags. Guidance was given on active self-care approaches consisting of pain neuroscience education designed with individualized pain curriculum, exercise therapy, manual therapy, and breathing exercises for a period of  sixweeks. Clinically meaningful improvements were obtained in the outcome measures of Numeric Pain Rating Scale (NPRS), Patient-Specific Functional Scale (PSFS), and Global Rating of Change (GROC) scale and progress in Pain-Self Efficacy Questionnaire (PSEQ) and Tampa Scale for Kinesiophobia (TSK) scores. Positive changes were achieved with functional activities (chewing, eating, yawing, brushing teeth and physical intimacy), and the patient was pain-free on discharge, which was maintained at a six-month follow-up.

Inter-examinerreliability study of physical examination procedures to assess the cervical spine

Objective

The objective of this study was to establish the level of inter-examiner reliability for six common cervical manual and physical examination procedures used to assess the cervical spine.

Materials:

Reliability study that used a convenience sample of 51 patients between the ages of 16–70 years presenting with a chief complaint of neck pain. Two physical therapists independently performed the same series of cervical physical examination procedures on each of the participant. The clinicians were blinded to each other’s findings and the clinical status of the patient. Kappa coefficients (κ) were calculated for levels of agreement between the clinicians for each procedure.

Results

When assessing for asymmetrical motion, excellent levels of reliability (κ range: 0.88–0.96) were observed for the Bilateral Modified Lateral Shear (asymmetry criterion), Bilateral C2 Spinous Kick (asymmetry criterion) and Flexion-Rotation Tests. When pain provocation was used as the indicator of a positive test during palpation of the cervical facet joints, moderate to substantial levels of reliability (κ range: 0.53–0.76) were observed. When patients were instructed not to provide feedback to the clinicians about pain provocation during facet joint palpation and clinicians relied solely on their qualitative assessment of segmental mobility, the level of reliability was lower (κ range: 0.45–0.53). Due to 100 % prevalence of negative findings, Kappa values could not be calculated for the Sharp-Purser test or the Unilateral C2 Spinous Kick Test.

Conclusions

Most physical examination procedures examined in this study demonstrated moderate to excellent levels of inter-examiner reliability. Palpation for segmental mobility without pain provocation demonstrated a lower level of reliability compared to palpation for pain provocation. Correlation with clinical findings is necessary to establish validity and the applicability of these procedures in clinical practice.

Between-week reliability of the cervical range of motion (CROM) device for upper cervical rotation

Background: The Cervical Range of Motion (CROM) device is a valid and reliable clinical tool used to measure full cervical rotation, however, its reliability for measuring upper cervical rotation is unknown.Objectives: Assess between-week test-retest reliability of the CROM device in measuring upper cervical rotationMethod: Thirty students participated in this test-retest reliability study. The CROM device was used to measure left and right cervical rotation in both a seated neutral and fully flexed head-neck position. Interclass correlation coefficient (ICC) was calculated for all motions. Measurement error was determined using standard error of measurement (SEM) and minimal detectable change (MDC).Results: The CROM device demonstrated moderate to good reliability (ICCs 0.65-0.9) of full and upper cervical rotation. The SEMs and MDCs of this study are small and suggest that the chance of repeated measurement error was relatively minimal for the between-week trials.Conclusions: The CROM device is a reliable outcome tool for measuring upper cervical rotation. The clinical implications of these findings suggest that therapists can utilize the CROM device to more completely examine all planes of upper and full cervical mobility. It may also assist in identifying upper cervical ROM limitations associated with underlying cervical pathology or motion dysfunction.

The association between specific temporomandibular disorders and cervicogenic headache

BACKGROUND AND AIMS

Upper neck signs, symptoms and hypomobility have been shown to present with a higher prevalence in patients with temporomandibular disorders (TMDs). However, there is currently no evidence of an association between specific TMDs and cervicogenic headache (CGH). Therefore, the aim of this study was to evaluate the odds ratio and the relative risk of CGH in patients with specific TMDs.

METHOD

116 participants, including 74 patients with TMD (pain-related/intraarticular/mixed TMD) and 42 healthy controls took part in this study. The TMD diagnosis was made by senior faculty members of the Dental School according to the Diagnostic Criteria for TMD, while the cervical diagnosis was made by a qualified senior physical therapist. The analysis comprised the evaluation of the odds ratio of CGH among patients with TMD and the relative risk (RR) for CGH during 14-24 months of follow-up.

RESULTS

Significantly higher odds ratios of cervicogenic headache were found among pain-related and mixed TMD (12.17 and 10.76, respectively) versus healthy controls. During the 14-24 months of follow-up, there was no significant difference of relative risk for CGH among patients with TMD versus healthy controls.

SUMMARY AND CONCLUSIONS

The results support a clear clinical association between painful TMD (pain-related and mixed TMD) and cervicogenic headache.

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.

Effects of the Manual Therapy Approach of Segments C0-1 and C2-3 in the Flexion-Rotation Test in Patients with Chronic Neck Pain: A Randomized Controlled Trial

Background: Flexion-rotation test predominantly measures rotation in C1-2 segment. Restriction in flexion-rotation may be due to direct limitation in C1-2, but also to a premature tightening of the alar ligament as a result of lack of movement in C0-1 or C2-3. The aim of this study was to compare the effect of a 20-min single cervical exercise session, with or without manual therapy of C0-1 and C2-3 segment in flexion-rotation test, in patients with chronic neck pain and positive flexion-rotation test. Methods: Randomized controlled clinical trial in 48 subjects (24 manual therapy+exercise/24 exercise). Range of motion and pain during flexion-rotation test, neck pain intensity and active cervical range of motion were measured before and after the intervention. Results: Significant differences were found in favour of the manual therapy group in the flexion-rotation test: right (p < 0.001) and left rotation (p < 0.001); pain during the flexion-rotation test: right (p < 0.001) and left rotation (p < 0.001); neck pain intensity: (p < 0.001); cervical flexion (p < 0.038), extension (p < 0.010), right side-bending (p < 0.035), left side-bending (p < 0.002), right rotation (p < 0.001), and left rotation (p < 0.006). Conclusions: Addition of one C0-C1 and C2-C3 manual therapy session to cervical exercise can immediately improve flexion-rotation test and cervical range of motion and reduce pain intensity.

Upper cervical range of rotation during the flexion-rotation test is age dependent: an observational study

Background:

The flexion-rotation test (FRT) is widely used to detect movement dysfunction in the spinal segment C1/C2, especially in patients with cervicogenic headache. The current published literature indicates that range recorded during the FRT is not age dependent. This is questionable, considering the well documented relationship between aging and degeneration in the cervical spine and loss of cervical movement in older people. The present study therefore aims to examine the influence of age on FRT mobility, and to provide normative values for different age groups. An additional aim is to examine the influence of age on the ratio between lower and upper cervical rotation mobility.

Methods:

For this cross-sectional, observational study, healthy subjects aged from 18 to 90 years were recruited. The upper cervical range of rotation during the FRT was measured using a digital goniometer. Personal data including age, weight, height, and lifestyle factors were also assessed.

Results:

A total of 230 (124 male) healthy, asymptomatic subjects, aged between 18 and 87 years were included. Regression analysis showed that 27.91% (p < 0.0001) of the variance in FRT mobility can be explained by age alone, while 41.28% (p < 0.0001) of the variance in FRT mobility can be explained by age and total cervical range of motion (ROM). Normative values for different age decades were calculated using regression analysis. No significant influence of age on the ratio between ROM of lower and upper cervical rotation was found. There was no relevant impact of personal (gender, height, and weight) and lifestyle (smartphone and PC use) factors on ROM during the FRT.

Conclusion:

Upper cervical rotation mobility determined by the FRT correlates strongly with age; hence, the results of the FRT have to be interpreted taking into account the individual age of the tested subject. The ratio between lower and upper cervical rotation mobility is maintained in all age groups.

Does Upper Cervical Manual Therapy Provide Additional Benefit in Disability and Mobility over a Physiotherapy Primary Care Program for Chronic Cervicalgia? A Randomized Controlled Trial

Introduction: Neck pain is a condition with a high incidence in primary care. Patients with chronic neck pain often experience reduction in neck mobility. However, no study to date has investigated the effects of manual mobilization of the upper cervical spine in patients with chronic mechanical neck pain and restricted upper cervical rotation. Objective: To evaluate the effect of adding an upper cervical translatoric mobilization or an inhibitory suboccipital technique to a conventional physical therapy protocol in patients with chronic neck pain test on disability and cervical range of motion. Design: Randomized controlled trial. Methods: Seventy-eight patients with chronic neck pain and restricted upper cervical rotation were randomized in three groups: Upper cervical translatoric mobilization group, inhibitory suboccipital technique group, or control group. The neck disability index, active cervical mobility, and the flexion-rotation test were assessed at baseline (T0), after the treatment (T1), and at three-month follow-up (T2). Results: There were no statistically significant differences between groups in neck disability index. The upper cervical translatoric mobilization group showed a significant increase in the flexion-rotation test to the more restricted side at T1 (F = 5.992; p < 0.004) and T2 (F = 5.212; p < 0.007) compared to the control group. The inhibitory suboccipital technique group showed a significant increase in the flexion-rotation test to the less restricted side at T1 (F = 3.590; p < 0.027). All groups presented high percentages of negative flexion-rotation tests. (T1: 69.2% upper neck translator mobilization group; 38.5% suboccipital inhibition technique group, 19.2% control group; at T2: 80.8%; 46.2% and 26.9% respectively). No significant differences in the active cervical mobility were found between groups. Conclusion: Adding manual therapy to a conventional physical therapy protocol for the upper cervical spine increased the flexion-rotation test in the short- and mid-term in patients with chronic neck pain. No changes were found in the neck disability index and the global active cervical range of motion.

Physician Medical Assessment in a Multidisciplinary Concussion Clinic

Concussive brain injury (CBI) is encountered by clinicians in sports medicine, pediatrics, neurosurgery, neurology, physiatry, and primary care. There is no gold standard diagnostic test for CBI, nor is there consensus on what neuromusculoskeletal physical examination tests should be performed on patients who have sustained CBI. This article presents an approach to the history and physical examination of the patient who has sustained a CBI that is based on a review of the literature evidence and the authors' extensive experience with this patient population. Suggested components include an elemental neurological examination that emphasizes the oculomotor/ophthalmologic and vestibular systems, as well as appropriate musculoskeletal assessment of the craniocervical and upper shoulder girdle complex. The use of supplementary tests for CBI, including assessment of exercise tolerance using the Buffalo Concussion Treadmill Test and tests of neurocognitive function, can aid in the differential diagnosis of CBI. The proposed protocol is envisioned for initial and follow-up assessments in the clinic after CBI, as well as for those with more protracted signs or symptoms. If symptoms persist beyond 2 weeks in adults or 4 weeks in adolescents, then referral to a multidisciplinary center that focuses on CBI is recommended.

"Short- and mid-term effects of adding upper cervical manual therapy to a conventional physical therapy program in patients with chronic mechanical neck pain. Randomized controlled clinical trial."

OBJECTIVE

To evaluate the effect of adding an Upper Cervical Translatoric Mobilization (UCTM) or an Inhibitory Suboccipital Technique (IST) to a physiotherapy treatment in the symptomatology and function of mechanical chronic neck pain patients.

DESIGN

Randomized controlled trial.

SETTING

Primary Care Center in Cornellà, Spain.

SUBJECTS

78 patients (64 women), with mean age (SD) of 59.96 (13.30) years with mechanical chronic neck pain were divided in three groups: control, IST and UCTM groups.

INTERVENTIONS

All groups received 15 physiotherapy sessions for three weeks. The UCTM and IST groups added 5 minutes of the assigned technique during six sessions.

MAIN MEASURES

Neck disability index (NDI) and numeric pain rating scale (NPRS) for neck pain were measured baseline, three-weeks and 15-weeks follow-up.

RESULTS

NDI (SD) at baseline, three-weeks and 15-weeks were 11.62 (7.08), 9.65 (6.25), 7.58 (5.64) for the control group, 14.38 (6.92), 8.50 (6.11), 7.12 (4.98) for the IST group and 13.19(7.23), 5.35(6.10), 4.35(2.76) for the UCTM group. NPRS (SD) at baseline, three-weeks and 15-weeks were 58.69 (19.46), 45.19 (23.43), 44.58 (24.08) for the control group; 64.08 (19.26), 42.19 (19.69), 34 (21.14) for the IST group; and 67.65 (20.65), 36.23 (20.10), 39.85 (25.44) for the UCTM group.

CONCLUSIONS

Compared with no treatment, both forms of mobilization were associated with reduced disability at three weeks, and UCTM remained better than control at 15 weeks; there were no significant differences between the two mobilization groups.

Does the Addition of Manual Therapy Approach to a Cervical Exercise Program Improve Clinical Outcomes for Patients with Chronic Neck Pain in Short- and Mid-Term? A Randomized Controlled Trial

Chronic neck pain is one of today’s most prevalent pathologies. The International Classification of Diseases categorizes four subgroups based on patients’ associated symptoms. However, this classification does not encompass upper cervical spine dysfunction. The aim is to compare the short- and mid-term effectiveness of adding a manual therapy approach to a cervical exercise protocol in patients with chronic neck pain and upper cervical spine dysfunction. Fifty-eight subjects with chronic neck pain and upper cervical spine dysfunction were recruited (29 = Manual therapy + Exercise; 29 = Exercise). Each group received four 20-min sessions, one per week during four consecutive weeks, and a home exercise regime. Upper flexion and flexion-rotation test range of motion, neck disability index, craniocervical flexion test, visual analogue scale, pressure pain threshold, global rating of change scale, and adherence to self-treatment were assessed at the beginning, end of the intervention and at 3- and 6-month follow-ups. The Manual therapy + Exercise group statistically improved short- and medium-term in all variables compared to the Exercise group. Four 20-min sessions of Manual therapy + Exercise along with a home-exercise program is more effective in the short- to mid-term than an exercise protocol and a home-exercise program for patients with chronic neck pain and upper cervical dysfunction.

Concurrent validity and reliability of measuring range of motion during the cervical flexion rotation test with a novel digital goniometer

BACKGROUND

Headache is a common and costly health problem. Although the pathogenesis of headache is heterogeneous, reported contributing factors are dysfunctions of the upper cervical spine. The flexion rotation test (FRT) is a commonly used diagnostic test to detect upper cervical movement impairment. A digital goniometer may support precise measurement of movement impairment in the upper cervical spine. However, its reliability and validity is not assessed, yet. The aim of this study was to investigate the reliability and validity of the digital goniometer compared to an ultrasound-based movement analysis system.

METHODS

Two separate cross-sectional studies were conducted using the digital goniometer EasyAngle (Meloq AB, Stockholm, Sweden) for a) investigating the concurrent validity of upper cervical range of motion (ROM) during the FRT and b) determining the inter- and intra-rater reliability in the target population of patients with head and neck pain. Sixty-two participants, 39 with and 23 without head and neck pain, were recruited for the concurrent validity study. For the reliability study, a total of 50 participants were recruited. Intraclass correlation coefficients (ICC) and Bland Altmann plots were used to assess validity and ICC values, Bland Altmann plots as well as Kappa coefficients were used for estimating intra-rater and inter-rater reliability.

RESULTS

Concurrent validity was strong with an ICC (2,1) of 0.97 for ROM to either side (95%CI = 0.95-0.98). Bland Altman Plots revealed a mean difference between measurement systems of 0.5° for the left and 0.11° for the right side. The inter-rater ICC (2,1) was 0.66 (95%CI 0.47-0.79, p <  0.001, SEM 6.6°), indicating good reliability. The limits of agreement were between 10.25° and - 11.89°, the mean difference between both raters was - 0.82°. Intra-rater reliability for the measurement of ROM during the FRT was between 0.96 (ICC 3,1) for rater 1 and 0.94 (ICC 3,1) for rater 2.

CONCLUSIONS

The digital goniometer demonstrated strong concurrent validity and good to strong reliability and can be used in clinical practice to accurately determine movement impairment in the upper cervical spine.

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.

Relationship between specific temporomandibular disorders and impaired upper neck performance

Upper neck impairments are more prevalent in patients with temporomandibular disorders (TMDs) but the differences between specific types of TMDs are unclear. This study evaluated the distribution of such impairments among different forms of TMD. In total, 116 participants (86 women and 30 men, age range 21-75 yr) were investigated. Forty-two individuals had no TMDs and were assigned to the control group. The remaining 74 patients were assigned to one of three groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) findings: pain-related (n = 37); intra-articular (n = 17); or mixed (combined pain-related and intra-articular) (n = 20). Analyses of impairments included between-group comparisons of key parameters of upper neck performance (active/passive mobility and muscular capabilities) and pain (subjective neck disability and pain sensitivity). Patients in the pain-related and mixed TMD groups were found to have decreased upper neck mobility in the cervical flexion-rotation test compared with patients in intra-articular and control groups, as well as poorer capabilities of the deep neck flexor muscles in the cranio-cervical flexion test compared to the control group. It was concluded that patients with pain-related TMD diagnoses are more likely to experience significant upper-neck hypomobility and poor muscular capabilities than patients with intra-articular diagnoses of TMD.

Temporomandibular disorders and cervicogenic dizziness: Relations between cervical range of motion and clinical parameters

OBJECTIVE

To analyze the cervical range of motion (CROM) and clinical parameters in patients affected by myogenous temporomandibular disorders (TMD), cervicogenic dizziness (CGD), both TMD and CGD (TMD/CGD), and a group of healthy subjects (HS).

METHODS

CROM degrees, Dizziness Handicap Inventory (DHI), Tampa Scale for Kinesiophobia (TSK-17), Hospital Anxiety and Depression Scale (HADS), and Jaw Functional Limitation Scale 20 (JFLS-20) scores were compared between 46 TMD patients, 49 CGD subjects, 43 TMD/CGD patients, and 98 HS.

RESULTS

TMD/CGD and CGD patients demonstrated significantly lower CROM degrees and higher DHI, TSK-17, and HADS values when compared to TMD patients. TMD/CGD and TMD patients demonstrated higher JFLS-20 values when compared to CGD and HS. Significant negative correlations were found in TMD/CGD and TMD patients between JFLS-20 and CROM in flexion and extension.

DISCUSSION

Present findings demonstrated a relation between spine movement impairment and TMD.

Validation of a clinical examination to differentiate a cervicogenic source of headache: a diagnostic prediction model using controlled diagnostic blocks

OBJECTIVES

Neck pain commonly accompanies recurrent headaches such as migraine, tension-type and cervicogenic headache. Neck pain may be part of the headache symptom complex or a local source. Patients commonly seek neck treatment to alleviate headache, but this is only indicated when cervical musculoskeletal dysfunction is the source of pain. Clinical presentation of reduced cervical extension, painful cervical joint dysfunction and impaired muscle function collectively has been shown to identify cervicogenic headache among patients with recurrent headaches. The pattern's validity has not been tested against the 'gold standard' of controlled diagnostic blocks. This study assessed the validity of this pattern of cervical musculoskeletal signs to identify a cervical source of headache and neck pain, against controlled diagnostic blocks, in patients with headache and neck pain.

DESIGN

Prospective concurrent validity study that employed a diagnostic model building approach to analysis.

SETTING

Hospital-based multidisciplinary outpatient clinic in Joliet, Illinois.

PARTICIPANTS

A convenience sample of participants who presented to a headache clinic with recurrent headaches associated with neck pain. Sixty participants were enrolled and thirty were included in the analysis.

OUTCOME MEASURES

Participants underwent a clinical examination consisting of relevant tests of cervical musculoskeletal dysfunction. Controlled diagnostic blocks of C2/C3-C3/C4 established a cervical source of neck pain. Penalised logistic regression identified clinical signs to be included in a diagnostic model that best predicted participants' responses to diagnostic blocks.

RESULTS

Ten of thirty participants responded to diagnostic blocks. The full pattern of cervical musculoskeletal signs best predicted participants' responses (expected prediction error = 0.57) and accounted for 65% of the variance in responses.

CONCLUSIONS

This study confirmed the validity of the musculoskeletal pattern to identify a cervical source of headache and neck pain. Adopting this criterion pattern may strengthen cervicogenic headache diagnosis and inform differential diagnosis of neck pain accompanying migraine and tension-type headache.

Changes in Vertebral Arterial Blood Flow During Premanipulative Tests in Participants With Upper Cervical Spine Motion Restriction

OBJECTIVE

The purpose of the present study was to measure changes in blood flow velocity and volume flow rate (VFR) in the contralateral vertebral artery (VA) during end-range rotation and pre-manipulative hold at C1-C2 and to compare these measurements between participants with and without C1-C2 range of motion (ROM) restriction.

METHODS

This research was approached as an exploratory study and designed as a parallel noninterventional controlled trial with intentionally equal allocation, for studying diagnostic tests. Fifteen women and 13 men (mean age 44) were recruited (volunteer sample) in physiotherapy clinics. No participant had any current neurologic or vertebrobasilar insufficiency symptoms. The measurements of 13 participants with a limited ROM C1-C2 and 15 with no limitation were compared. Blood flow velocity and VFR in the contralateral VA were measured using color duplex Doppler imaging in 3 neck positions: neutral, maximal rotation, and pre-manipulative hold of C1-C2.

RESULTS

Pre-manipulative hold significantly (P < .01) decreased all blood flow velocity parameters and VFR, mainly in the left VA. End-range rotation showed a significant (P < .05) decrease in the peak systolic velocity in the left VA. No significant differences were found between participants grouped by the presence or absence of a C1-C2 ROM restriction.

CONCLUSION

A C1-C2 rotational ROM restriction does not appear associated with change in a significantly reduced VA blood flow due to the neck position.
