The flexion–rotation test and active cervical mobility—A comparative measurement study in cervicogenic headache

Differences in physical examination findings between those who present with or without headache soon after a whiplash injury: a cross-sectional study

AIM

To determine differences in physical examination findings between people with acute whiplash-associated disorders (WAD) with and without headache.

METHODS

In this cross-sectional study, participants with acute WAD were evaluated to assess differences in the presence of physical impairments. The following were assessed: pain intensity on manual palpation the over spinous process of C1-C3, zygapophyseal joints of C0-C4, and trapezius, sternocleidomastoid, suboccipitalis, masseter and temporalis muscles; cervical range of motion (ROM); flexion-rotation test (FRT); forward head posture; cranio-cervical flexion test (CCFT); neck flexor and extensor endurance; pressure-pain thresholds (PPT) over neural structures and upper limb neural tests (ULNT) in addition to median UNLT + CCF. Correlation analyses were performed to assess the association between examination findings and headache intensity. Logistic regression and discriminant analyses were also performed.

RESULTS

Forty-seven participants (26 men and 21 women; mean age = 38.9 years old) were included in the study. 60% of the participants presented with headache. Several examination findings were significantly different between groups. A group of examination findings composed of neck endurance, manual palpation over cervical and muscular structures, PPT, CCFT, ROM and FRT could discriminate between groups with a sensitivity of 86.7% and specificity of 90%.

CONCLUSIONS

Several neuromusculoskeletal features are different between people with acute WAD with or without headache. A combination of features could distinguish between groups with high levels of sensitivity and specificity.

Dry needling in the management of chronic tension-type headache associated with levator scapulae syndrome: A case report

Key Clinical Message

The use of DN to the muscular trigger points and distal periosteal enthesis of the levator scapulae may be a useful adjunct intervention within a multi-modal plan of care for the management of work-related chronic tension-type headaches associated with LSS.

Abstract

Chronic tension-type headaches (CTTH) have a lifetime prevalence of 42% and account for more lost workdays than migraine headaches. Dry needling (DN) is being increasingly used by physical therapists in the management of CTTH; however, to date, the supporting evidence is limited. The purpose of this case report was to describe how three sessions of DN targeting myofascial trigger points in the levator scapulae (LS) muscle and its distal enthesis was used to treat a 63-year-old male patient who presented with work-related CTTH associated with levator scapulae syndrome (LSS). The patient was treated for five visits over the course of 2 months. At discharge and 6-month follow-up, the patient reported full resolution of symptoms. Self-report outcomes included the numeric pain rating scale and the Neck Disability Index. The use of DN to the LS muscle and its distal enthesis may be a valuable addition to a multi-modal plan of care in the treatment of work-related CTTH associated with LSS.

Reliability and measurement properties of upper cervical flexion-extension range of motion testing in people with cervicogenic headache and asymptomatic controls

OBJECTIVE

The objective was to determine reliability of sagittal plane range of motion (ROM) assessment in a healthy population and in people with cervicogenic headache (CGH).

METHODS

Upper cervical flexion/extension ROM was measured using an iPhone magnetometer sensor and retraction/protraction ROM measured by linear displacement. Two independent raters evaluated these movements in 33 subjects with CGH and 33 age and gender matched asymptomatic healthy controls on two occasions. Measurement procedures were standardized; and the order of testing randomized. Reliability, standard error of measurement (SEM) and minimum detectable change (MDC) were calculated.

RESULTS

Subjects comprised 30 females and 36 males. The iPhone method demonstrated high reliability (ICC >0.82) with SEM values ranging from 0.62 to 1.0 and MDC values ranging from 1.70 to 4.81 respectively. Evaluation of linear displacement demonstrated moderate reliability (ICC >64). with SEM values ranging from 0.38 to 1.91 and MDC values ranging from 1.05 to 1.63 respectively. Compared to healthy controls, upper cervical flexion, retraction and protraction ROM was significantly less in the CGH group with mean difference of 6.50°, 1.52 cm and 2.34 cm respectively.

DISCUSSION

Upper cervical spine sagittal plane ROM can be measured with moderate to high reliability and was found to be more restricted in people with 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.

Application of biomechanical principles to upper cervical spine anatomy to alleviate symptoms of intermittent cranial nerve IX irritation. Directions for successful self-management of headache post-concussion? A case series

BACKGROUND

The neck has been implicated as a potential generator of symptoms such as dizziness and headache in individuals with persistent symptoms post concussion. Anatomically, the neck could also be a potential trigger for autonomic or cranial nerve symptoms. The glossopharyngeal nerve which innervates the upper pharynx is one possible autonomic trigger that might be affected by the upper cervical spine.

CASE DESCRIPTION

This is a case series of three individuals with persistent post-traumatic headache (PPTH) and symptoms of autonomic dysregulation who also had signs of intermittent glossopharyngeal nerve irritation associated with certain neck positions or movements. Biomechanical principles were applied to anatomical research on the path of the glossopharyngeal nerve, in relation to the upper cervical spine and the dura mater, to alleviate these intermittent symptoms. The patients were provided techniques to be used as tools to immediately alleviate the intermittent dysphagia, which also alleviated the constant headache at the same time. As part of the overall long-term management program, patients were also taught daily exercises to improve upper cervical and dural stability and mobility.

OUTCOME

The result was a decrease in intermittent dysphagia, headache, and autonomic symptoms in the long term in persons with PPTH following concussion.

DISCUSSION

Autonomic and dysphagia symptoms may provide clues as to the origin of symptoms in a subgroup of individuals with PPTH.

Elastic Modulus of Suboccipital Muscles, Cervical Range of Motion, and Forward Head Posture in Cervicogenic Headache

Background

Although stiffness of neck muscles, the limitation of cervical range of motion (ROM), and forward head posture (FHP) are proposed as clinical characteristics of cervicogenic headache (CGH), adequate consistent data failed to support these characteristics.

Objective

This study aims to compare the elastic modulus of suboccipital muscles, cervical ROM, and FHP between individuals suffering from CGH and healthy controls.

Material and Methods

In this cross-sectional study, 20 individuals with a history of CGH and 20 normal individuals participated. Sonography images and a universal goniometer (UG) were used to assess elastic modulus and cervical ROM, respectively. In addition, FHP was assessed based on measuring craniovertebral angle (CVA) using a digital imaging technique and also the distance of anterior tragus of the ear with the vertical line passed from anterior of lateral malleolus according to the Kendall and McCreary method.

Results

Elastic modulus of suboccipital muscles in the CGH group was significantly higher than that of the normal group (P=0.008). The two groups were not significantly different in terms of FHP. Moreover, ROM of cervical extension (P=0.035), right rotation (P=0.046), and left rotation (P=0.018) showed a significant reduction in the CGH group compared to the control group.

Conclusion

Suboccipital muscles are stiffer and ROM of cervical rotation and extension is smaller in CGH patients than the healthy controls, but FHP is not different between the groups, leading to diagnosing CGH and treatment.

Headache production during physical examination in patients with and without headache attributed to a whiplash injury: A case-control study

BACKGROUND

Provocation of headache on physical examination of the neck may reflect a role of cervical structures in the presence of acute whiplash-associated headache (WAH).

OBJECTIVE

To determine differences in headache provocation during physical tests in people with and without WAH after a whiplash injury.

DESIGN

Case-control study.

METHODS

Forty-seven people with acute whiplash-associated disorders participated, 28 with WAH. Passive accessory intervertebral movement over the tubercle of C1, the spinous processes of C2-C3 and facet joints of C0-C4, the flexion-rotation test (FRT), manual palpation of cranio-cervical muscles and the upper limb neurodynamic test + cranio-cervical flexion were assessed bilaterally twice by a blinded examiner; headache provocation was determined. Cohen's kappa and Chi-squared were determined to evaluate the intra-rater reliability of test results and differences between groups, respectively. A logistic regression model was also performed.

RESULTS

Intra-rater reliability of headache provocation was good or excellent for most tests. Significant differences between groups were found with higher positive tests in WAH for the assessment of C2 (68%), the most painful side of C0-C1 (57%), C1-C2 (75%) and C2-C3 (53%), most (79%) and least (25%) restricted sides of the FRT, and manual palpation of the most painful side for the trapezius (53%), masseter (50%) and temporalis (46%) muscles. Provocation of headache during the assessment of C2 and C1-C2 on the most painful side demonstrated the highest association with WAH.

CONCLUSION

Mechanical provocation of headache is more frequent in people with WAH than in those without headache soon after a whiplash injury.

Impact of Movement Control Training Using a Laser Device on the Neck Pain and Movement of Patients with Cervicogenic Headache: A Pilot Study

This study verified the effect of movement control training using a laser device on the neck pain and movement of patients with cervicogenic headache. A total of twenty outpatients recruited from two Busan hospitals were equally divided into two groups. The experimental group underwent movement control training with visual biofeedback, while the control group performed self-stretching. Both groups received therapeutic massage and upper cervical spine mobilization. A four-week intervention program was also conducted. Measurement tools including the cervical flexion-rotation test, visual analog scale, Headache Impact Test-6, pressure pain threshold, range of motion, sensory discrimination, and Neck Disability Index helped assess the participating patients before and after the intervention. Additionally, the Wilcoxon signed-rank test and the Mann-Whitney U test helped determine inter and intra-group variations, respectively, before and after the intervention. Most of the measurement regions revealed significant changes post-intervention within the experimental group, while only the cervical flexion-rotation test, visual analog scale, Headache Impact Test-6, and Neck Disability Index indicated significant changes post-intervention within the control group. There were also considerable inter-group differences. Thus, movement control training using a laser device more effectively improves neck pain and movement of patients with cervicogenic headache.

Sub-occipital muscle pressure pain thresholds correlate to direction of symptomatic active comfortable sustained neck rotation testing in post-concussive headache: a retrospective observational cross-sectional study

OBJECTIVES

To compare sub-occipital muscle pressure sub pain thresholds (PPTs) in individuals with persistent-post-traumatic-headache (PPTH) in relation to the presence or not of cranial nerve and/or autonomic symptoms reported during sustained neck rotation (SNR).

BACKGROUND

Previously 81% of military service members with PPTH demonstrated symptoms with SNR up to 60 seconds. Of these, 54% reported symptoms in one (Uni-Symp) and 46% in both directions of rotation (Bi-Symp). Sub-occipital PPTs, in relation to SNR direction, were of interest.

METHODS

Retrospective review of records of 77 individuals, with PPTH with both SNR and PPTs. Average suboccipital and scalene PPTs were compared between Asymptomatic (n = 13), upon SNR testing, or Symptomatic (Uni-Symp, n = 32, Bi-Symp, n = 32), groups.

RESULTS

The Bi-Symp group had significantly reduced sub-occipital PPTs relative to the Asymptomatic group on both sides [p < 0.009] with no side-to-side differences in either group. The Uni-Symp group had significantly lower sub-occipital PPTs on the symptomatic SNR test direction compared to the asymptomatic side [t(31) = 3.37, p = 0.002]. There were no differences within or between groups in the scalene PPTs(p's > 0.08).

CONCLUSIONS

An upper cervical mechanical trigger of symptoms during SNR tests in some individuals with PPTH is possible. The direction of symptomatic SNR tests may indicate direction of guarded hypermobile dysfunction and direct treatment.

Physical testing in patients with acute whiplash-associated disorders: A within session test-retest reliability study

BACKGROUND

People with whiplash-associated disorders (WAD) commonly present with a variety of physical impairments. However, the reliability of physical tests has not been established for patients with acute WAD.

OBJECTIVE

To assess test-retest reliability of different physical tests in acute WAD.

DESIGN

Intra-rater test-retest reliability.

METHODS

Patients with acute WAD were recruited. Physical tests were used to evaluate articular, muscular and neural systems in two blocks of measurements separated by 10 min. Bland-Altman plots were performed to assess intrarater agreement, which included calculation of the mean difference (d) between rates, the 95% CI for d, the standard deviation of the differences and the 95% limits of agreement. Reliability was calculated via the standard error of measurement, the minimal detectable change, percent of agreement, the intraclass-correlation coefficient, and kappa coefficient.

RESULTS

47 patients participated. Test-retest reliability was excellent or good for almost all measures, except for extension ROM, ULTT for the radial nerve, and active cervical extension and upper cervical rotation performed in 4-point kneeling, which presented moderate reliability. Systematic bias was found in cervical ROM in flexion, left and right lateral-flexion, left and right rotation; left ULTT for radial nerve; right trapezius, suboccipitalis and temporalis muscles, left temporalis; C3, both sides of C1-C2, left C3-C4.

CONCLUSION

The majority of physical tests achieved good or excellent test-retest intra-rater reliability when tested in patients with acute WAD. Findings must be considered with caution for those tests which demonstrated systematic bias. Additional research is warranted to evaluate inter-rater reliability.

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.

A perspective on the use of the cervical flexion rotation test in the physical therapy management of cervicogenic headaches

BACKGROUND

The Cervical Flexion-Rotation Test (CFRT) is widely used in the assessment of upper cervical spine mobility impairments and in the diagnosis of cervicogenic headache (CGH) by physiotherapist. Many studies investigated its different properties, and the results show that the CFRT has good construct validity in the measurement of C1-C2 rotation as well as good to excellent reliability.

PURPOSE

In this theoretical paper, we explore the value and point out two methodological issues associated to the CFRT, one related to the procedures and another related to its diagnostic accuracy.

RESULTS

Our analysis indicate that there are many confounding factors that could affect the CFRT cut-off's accuracy, which are likely to overestimate the diagnosis properties of CFRT. Potential solutions are discussed. Moreover, the gold standard (manual examination) used to examine the validity of the CFRT for the diagnosis of CGH appears to be far from perfect - we could argue that the diagnostic properties of the CFRT for CGH might be biased and the likelihood ratios are likely to be overestimated. However, it could be relevant to explore if results of the CFRT could be considered as a treatment-effect modifier. Maybe the CFRT could be more valuable as a prognostic factor?

CONCLUSION

The quality of evidence supporting the validity of the CFRT is most likely biased. In the absence of a better gold standard, maybe the CFRT could be a more valuable test to establish the patient's prognosis and help the clinician to choose the most appropriate treatment options.

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.

The effectiveness of Sustained Natural Apophyseal Glide on Flexion Rotation Test, pain intensity, and functionality in subjects with Cervicogenic Headache: A Systematic Review of Randomized Trials

OBJECTIVE

To determine the effect of sustained natural apophyseal glide (SNAG) on Flexion Rotation Test, pain intensity, and functionality in subjects with Cervicogenic Headache (CH).

METHODS

The research was conducted on five computerized databases PubMed/Medline, Web of Science, PEDro, Lilacs, and Cochrane Library (CENTRAL), using the keywords combination: (sustained natural apophyseal glide OR SNAG OR joint mobilization OR Mulligan) AND (cervicogenic headache) according to PRISMA guidelines. The methodological quality of the included studies was analyzed using the Physiotherapy Evidence Database (PEDro) scale.

RESULTS

Eight articles fulfilled the eligibility criteria and were included in the review. The selected studies had a methodological quality of 6.6/10 on the PEDro scale and included a total of 357 participants. The SNAG significantly improved pain, Flexion Rotation Test and reduced functional symptoms.

CONCLUSION

The available evidence suggests that SNAG may be a relevant intervention for CH.

The University of Kansas Health System Outpatient Clinical Concussion Comprehensive Protocol: An Interdisciplinary Approach

Objective:

The concussion team at The University of Kansas Health System outpatient rehabilitation spine center is comprised of experienced multi-disciplinary experts including physical therapists and a speech language pathologist. The team set forth with a purpose of creating and organizing an internal physical therapy clinical recommendation protocol for initial evaluations and subsequent treatments for the concussed patient. The aim of this paper is to share these recommendation protocols with other therapy teams and provide a foundational layout for treating the patient with post-concussion symptoms in an outpatient physical therapy clinical setting.

Study design:

Clinical recommendation protocol provides guidance for patients ages 10+ from initial evaluation through discharge with emphasis on evidence-based research in the areas of: oculomotor, cervical, vestibular, post-concussion migraine influence, mood disorders(such as anxiety and depression), exertion, and cognitive communicative dysfunction.

Results:

Finding a written, comprehensive clinical resource protocol for post-concussion outpatient evaluation(s) and treatment strategies can be difficult. This document serves as a resource for other outpatient concussion rehabilitation clinics, providing rationale, and objective measurement tools, for assessing and treating concussion patients. To the authors’ knowledge, no other research has produced a practical, efficient evaluation tool to be utilized at bed side, condensing evidence-based research into an easy-to-use form.

Conclusion:

The University of Kansas Health System outpatient concussion rehabilitation center developed clinical recommendation protocols for concussion care. The intent was to standardize assessment and treatment for concussion patients and to share these objective measurement tools and procedures, focused on a team approach of concussion providers, as a clinical outline for both the novice and seasoned clinician specializing in the field of concussion work in an outpatient rehabilitation setting.

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.

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.

Teaching Physiotherapy Students Physical Examination Skills by Using Photogrammetry: A Randomized Control Trial of 3- Versus 2-Dimensional Images

INTRODUCTION

Education research explains how healthcare professional training could be more efficient and effective by integrating simulation technology. Despite its relevance in training medical students, the evidence of its effectiveness in the manual skill training of physiotherapy students remains limited. The aim of this study was to compare the effectiveness of 3-dimensional (3D) images of real objects produced by photogrammetry and traditional 2-dimensional (2D) images when introducing manual therapy skills to undergraduate physiotherapy students via an online course.

METHODS

In a randomized controlled trial, a group of first-year physiotherapy bachelor honor degree students participated in a 2-hour online course on 3 manual assessment skills: cervical compression, distraction, and flexion-rotation tests. They demonstrated 2 sets of learning materials, including either 3D images of real rotating objects using close-range photogrammetry (experimental group) or traditional 2D images (control group). After their respective training, an Objective Structured Clinical Evaluation procedure was conducted to demonstrate their knowledge about the techniques. A standardized 9-item practical performance test was used as the primary outcome measure for the analyses.

RESULTS

Seventy-seven students participated in the study. The average Objective Structured Clinical Evaluation score for the experimental group (n = 40) was 41.3/50 (±3.9) and the control group (n = 37) was 39.1/50 (±4.5, P = 0.02).

CONCLUSIONS

For learning 3 cervical spine assessment skills, this study shows that photogrammetry creates 3D images of real rotating objects that are more effective than 2D images for first-year physiotherapy students.

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

Background

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

Purpose

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

Methods

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

Results

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

Conclusion

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

Cervical musculoskeletal impairments in migraine

Background

Neck pain is common and disabling amongst individuals with migraine. Cervical musculoskeletal interventions are often sought but there is currently no evidence to support such interventions for this population. Improved understanding of how cervical musculoskeletal impairments present in migraine can elucidate neck pain mechanisms and guide clinicians and researchers in the management of patients with migraine and neck pain.

Main body

Migraine hypersensitivity is a major consideration when assessing for cervical impairments as it can aggravate migraine and confound findings. Current evidence of cervical impairments in migraine is limited by disregard for the different underlying causes of neck pain and possible influence of hypersensitivity. Findings of cervical musculoskeletal impairments are mixed within and across studies, indicating that different forms of neck pain are present in migraine. Some migraineurs have neck pain that is part of the migraine symptom complex and therefore exhibit little or no cervical musculoskeletal impairment. Others have a cervical source of neck pain and therefore exhibit a pattern of cervical musculoskeletal impairments akin to that of cervical disorders. The presence of cervical musculoskeletal dysfunction may or may not be related to migraine but knowledge of this is currently lacking which impacts decision making on management. Cervical musculoskeletal interventions may be indicated for migraineurs with identified cervical dysfunction but other factors requiring further clarification include determination of i) patient specific outcomes, ii) impact of co-existing migraine referred neck pain, and iii) potential moderating effects of migraine hypersensitivity on treatment efficacy.

Conclusions

Physiotherapists should seek a combination of cervical impairments through skilful assessment to identify if cervical musculoskeletal dysfunction is present or not in individual patients. The relevance of cervical dysfunction to migraine and influence of co-existing migraine referred neck pain need to be established through detailed evaluation of pain behaviours and further research. Future clinical trials should define expected treatment outcomes and select individuals with cervical musculoskeletal dysfunction when investigating the efficacy of cervical musculoskeletal interventions.

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.

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.

Neck pain associated with migraine does not necessarily reflect cervical musculoskeletal dysfunction

OBJECTIVE

To identify how frequently the neck pain associated with migraine presents with a pattern of cervical musculoskeletal dysfunction akin to cervical musculoskeletal disorders, and to determine if pain hypersensitivity impacts on cervical musculoskeletal function in persons with migraine.

BACKGROUND

Many persons with migraine experience neck pain and often seek local treatment. Yet neck pain may be part of migraine symptomology and not from a local cervical source. If neck pain is of cervical origin, a pattern of musculoskeletal impairments with characteristics similar to idiopathic neck pain should be present. Some individuals with migraine may have neck pain of cervical origin, whereas others may not. However, previous studies have neglected the disparity in potential origins of neck pain and treated persons with migraine as a homogenous group, which does not assist in identifying the origin of neck pain in individuals with migraine.

METHODS

This cross-sectional, single-blinded study was conducted in a research laboratory at the University of Queensland, Australia. Persons with migraine (total n = 124: episodic migraine n = 106, chronic migraine = 18), healthy controls (n = 32), and persons with idiopathic neck pain (n = 21) were assessed using a set of measures typically used in the assessment of a cervical musculoskeletal disorder, including cervical movement range and accuracy, segmental joint dysfunction, neuromuscular and sensorimotor measures. Pain hypersensitivity was assessed using pressure pain thresholds and the Allodynia Symptom Checklist. People with migraine with diagnoses of comorbid neck disorders were excluded. Cluster analysis was performed to identify how participants grouped on the basis of their performance across cervical musculoskeletal assessments. Post hoc analyses examined the effects of pain hypersensitivity on musculoskeletal function, and if any symptoms experienced during testing were related to musculoskeletal function.

RESULTS

Two distinct clusters of cervical musculoskeletal function were found: (i) neck function similar to healthy controls (n = 108) and (ii) neck dysfunction similar to persons with neck pain disorders (n = 69). Seventy-six of the individuals with migraine (62 with neck pain and 14 without neck pain) were clustered as having normal cervical musculoskeletal function, whereas the remaining 48 with neck pain had cervical dysfunction comparable with a neck disorder. Musculoskeletal dysfunction was not related to pain hypersensitivity or symptoms experienced during testing.

CONCLUSIONS

Neck pain when present with migraine does not necessarily indicate the existence of cervical musculoskeletal dysfunction. Skilled assessment without reliance only on the person reporting symptoms is needed to identify actual cervical dysfunction. Treatments suitable for neck musculoskeletal disorders would seem inappropriate for the individuals without cervical dysfunction. Future studies evaluating any potential effects of such treatments should only select participants with neck pain of cervical origin.

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.

Short-term effects of an upper cervical spine traction-manipulation program in patients with cervicogenic dizziness: A case series study

BACKGROUND

Damage on the somatosensory system could cause sensation of dizziness, a condition known as cervicogenic dizziness (CD). Manual physical therapy has shown beneficial effects, relieving the symptoms of cervicogenic dizziness. However, the effect of upper cervical spine manipulation is unknown, as this is a technique that respects the International Federation of Orthopedic Manipulative Physical Therapists (IFOMPT) safety criteria.

OBJECTIVE

To assess the effects of upper cervical spine traction-manipulation in subjects with cervicogenic dizziness.

METHODS

This was a descriptive case series study. Treatment focused on the upper cervical spine manipulation procedure. Evaluation was performed before and after the treatment. Variables recorded include upper and lower cervical range of motion, Cervical Flexion-Rotation Test (CFRT), dizziness intensity and cervical pain (VAS), self-perceived dizziness measured with Dizziness Handicap Inventory (DHI) and subjective perception of outcome (GROC-scale).

RESULTS

Ten subjects were recruited. After the treatment protocol, there was an increased range of movement towards the most restricted side, as measured by the CFRT (p< 0.001), decreased intensity of dizziness (p< 0.001) and intensity of pain (p< 0.001). Functional capacity also improved after the intervention (p< 0.011).

CONCLUSION

Upper cervical spine manipulation may decrease dizziness intensity and cervical pain and improve functional ability and upper cervical spine mobility in patients with cervicogenic dizziness.

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.

Are there gender differences in neck pain and musculoskeletal disorders of the cervical spine associated with migraine?

OBJECTIVE

To evaluate gender differences in clinical characteristics of migraine by examining presence and severity of cutaneous allodynia, migraine-related disability, neck pain and its associated disability, passive mobility of the upper cervical spine, and performance of the deep neck flexor muscles.

DESIGN

cross-sectional study.

SUBJECTS

30 men and 30 women with migraine.

METHODS

Participants responded to the questionnaires Migraine Disability Assessment questionnaire, 12-item Allodynia Symptom Checklist and Neck Disability Index. The mobility of the upper cervical spine was assessed by using the Flexion-Rotation Test. Performance of the deep neck flexor muscles was evaluated by applying the Craniocervical Flexion Test. Comparison of the groups was carried out by using the Student's t-test or the chi-square test. The prevalence ratio was also calculated.

RESULTS

Women showed a higher prevalence of cutaneous allodynia (p = 0.001) and a 4 times greater risk of having severe cutaneous allodynia than to men (p = 0.007). No gender differences were observed in migraine-related disability (p = 0.08). Women showed higher prevalence of self-reported neck pain (p = 0.03) and increased risk of having this symptom in comparison to men (Prevalence Ratio=1.69; p = 0.025). However, there were no gender differences in neck pain-related disability (p = 0.25), mobility of the upper cervical spine (p = 0.92), or performance of the deep neck flexor muscles (p = 0.52).

CONCLUSION

Women with migraine had a higher frequency of self-reported neck pain and higher prevalence and severity of cutaneous allodynia when compared to men. However, the two groups did not differ regarding neck pain-related disability and performance in the physical tests.

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). .

The C0-C2 axial rotation test - Reliability and correlation with the flexion rotation test in people with cervicogenic headache and migraine

OBJECTIVES

The C0-C2 axial rotation test is a measure of upper cervical range of motion (UCROM), reported to be reliable in a headache free population. The objective was to determine the intra- and inter-rater reliability of the C0-C2 axial rotation test in people with a diagnosis of cervicogenic headache (CGH) or episodic migraine.

METHODS

Two therapists independently evaluated UCROM during the C0-C2 axial rotation test and flexion-rotation test (FRT) with an iPhone in 70 subjects (mean age 37.7 SD 11.6 years) with a diagnosis of CGH (35 subjects) or episodic migraine (35 subjects) on two occasions. Measurement procedures were standardized; and the order of testing randomized.

RESULTS

Reliability of the C0-C2 axial rotation test was moderate to high (ICC > 0.70). The standard error of measurement and minimum detectable change for this test were at most 2°. In subjects with CGH mean UCROM to the most restricted side was 9.3° (1.9) and 8.8° (2.1) for rater 1 and 2 respectively. While in patients with episodic migraine mean UCROM to the restricted side was 13.7° (1.6) and 13.6° (2.0) for rater 1 and 2 respectively.

DISCUSSION

The C0-C2 axial rotation test has at least moderate levels of reliability and correlates well with mobility determined by the FRT.

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.

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.

Interaction between Pain, Disability, Mechanosensitivity and Cranio-Cervical Angle in Subjects with Cervicogenic Headache: A Cross-Sectional Study

The relationship between the forward head posture and mechanosensitivity in subjects with a cervicogenic headache (CGH) remains uncertain. The aim of the study was to evaluate if there was a relationship between the tissue mechanosensitivity and cranio-cervical angle (CCA) that was moderated by pain intensity and/or disability in subjects with CGH. A convenience sample of 102 subjects was recruited. The CCA was measured with photographs, using a postural assessment software. The pain intensity was measured with a visual analogue scale (VAS), and the disability was measured with the Northwick Park Questionnaire. The pressure pain threshold (PPT) was measured at the spinous process of C2, the upper trapezius and splenius capitis muscles, and the median nerve. Simple moderation multiple regression analyses were constructed. There was a positive relationship between PPT at C2 and CCA, but a nonsignificant relationship for the PPT measured at the muscles and median nerve. The effect of PPT at C2 over CCA was moderated by pain intensity (R² = 0.17; R² change = 0.06; p < 0.05) but not disability. The Johnson–Neyman analysis revealed a cut-off point for the statistical significance of 4.66 cm in VAS. There seems to be a positive relationship between PPT at C2 and CCA, which is positively moderated by pain intensity in subjects with CGH.

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.

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.

Headache and neck

Cervicogenic headache (CEH) is currently identified with different diagnostic criteria. The latest one is the International classification of headache disorders (ICHD), 3rd edition (2018). At the present time, there are not enough published articles with reliable sensitivity and specificity that may support a classification for clinical and research purposes. Current literature suggests improvement to the classification(s). The ICHD criteria should be modified to reach an optimal sensitive and specific level to identify CEH as a secondary headache. The B, C1, and C2 criteria should be implemented with proposed suggestions. The C3 criterion should be upgraded. Criteria such as mechanical precipitation of pain by digital pressure on neck trigger points and specific movements, strictly unilateral pain without side-shift, diffuse unilateral shoulder and arm pain, pain starting posteriorly and spreading anteriorly should be integral part of the classification.

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.

International consensus on the most useful assessments used by physical therapists to evaluate patients with temporomandibular disorders: A Delphi study

OBJECTIVE

To identify assessment tools used to evaluate patients with temporomandibular disorders (TMD) considered to be clinically most useful by a panel of international experts in TMD physical therapy (PT).

METHODS

A Delphi survey method administered to a panel of international experts in TMD PT was conducted over three rounds from October 2017 to June 2018. The initial contact was made by email. Participation was voluntary. An e-survey, according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES), was posted using SurveyMonkey for each round. Percentages of responses were analysed for each question from each round of the Delphi survey administrations.

RESULTS

Twenty-three experts (completion rate: 23/25) completed all three rounds of the survey for three clinical test categories: 1) questionnaires, 2) pain screening tools and 3) physical examination tests. The following was the consensus-based decision regarding the identification of the clinically most useful assessments. (1) Four of 9 questionnaires were identified: Jaw Functional Limitation (JFL-8), Mandibular Function Impairment Questionnaire (MFIQ), Tampa Scale for Kinesiophobia for Temporomandibular disorders (TSK/TMD) and the neck disability index (NDI). (2) Three of 8 identified pain screening tests: visual analog scale (VAS), numeric pain rating scale (NRS) and pain during mandibular movements. (3) Eight of 18 identified physical examination tests: physiological temporomandibular joint (TMJ) movements, trigger point (TrP) palpation of the masticatory muscles, TrP palpation away from the masticatory system, accessory movements, articular palpation, noise detection during movement, manual screening of the cervical spine and the Neck Flexor Muscle Endurance Test.

CONCLUSION

After three rounds in this Delphi survey, the results of the most used assessment tools by TMD PT experts were established. They proved to be founded on test construct, test psychometric properties (reliability/validity) and expert preference for test clusters. A concordance with the screening tools of the diagnostic criteria of TMD consortium was noted. Findings may be used to guide policymaking purposes and future diagnostic research.

Measurement of range-of-motion in infants with indications of upper cervical dysfunction using the Flexion-Rotation-Test and Lateral-Flexion-Test: a blinded inter-rater reliability study in a clinical practice setting

Background: In infants with indications of upper cervical dysfunction, the Flexion-Rotation-Test and Lateral-Flexion-Test are used to indicate reduced upper cervical range-of-motion (ROM). In infants, the inter-rater reliability of these tests is unknown.

Objective: To assess the inter-rater reliability of subjectively and objectively measured ROM by using the Flexion-Rotation-Test and Lateral-Flexion-Test.

Methods: 36 infants (<6 months) and three manual therapists participated in this cross-sectional observational study. Pairs of two manual therapists independently assessed infants’ upper cervical ROM using the Flexion-Rotation-Test and Lateral-Flexion-Test, blinded for each other’s outcomes. Two inertial motion sensors objectively measured cervical ROM. Inter-rater reliability was determined between each pair of manual therapists. For subjective outcomes, Cohen’s kappa (ĸ) and the proportion of agreement (Pra) were calculated. For objectively measured ROM, Bland Altman plots were conducted and Limits of Agreement and Intraclass Correlation Coefficients (ICC) were calculated.

Results: The inter-rater reliability of the Flexion-Rotation-Test and Lateral-Flexion-Test for subjective (ĸ: 0.077–0.727; Pra: 0.46–0.86) and objective outcomes (ICC: 0.019–0.496) varied between pairs of manual therapists.

Conclusion: Assessed ROM largely depends on the performance of the assessment and its interpretation by manual therapists, leading to high variation in outcomes. Therefore, the Flexion-Rotation-Test and Lateral-Flexion-Test cannot be used solely as a reliable outcome measure in clinical practice and research context.

Bruxism, temporomandibular dysfunction and cervical impairments in females - Results from an observational study

PURPOSE

Bruxism is highly prevalent and defined as abnormal habitual mouth activity including clenching of the teeth and increased jaw muscle activity. The association between bruxism and temporomandibular dysfunction (TMD) is debated, in particular the association between cervical spine impairments, bruxism, and TMD. Hence the purpose of this study was to identify the relationship between bruxism, TMD, and cervical spine impairments.

METHODS

This observational study categorized 55 female volunteers suitable for evaluation to a bruxism (n = 33) or non-bruxism group (n = 22) based on comprehensive screening using questionnaires and visual observation of the mouth by 2 independent dentists. Following this, both groups were evaluated for TMD, severity and location of head/neck pain, neck disability index (NDI), cervical spine impairments, and tissue mechanosensitivity. Regression analysis was used to evaluate the relationship between bruxism, TMD severity, and cervical impairments.

RESULTS

Coefficients of pain and bruxism were significantly associated with NDI scores (0.43, p < 0.001; 3.24, p = 0.01) with large and medium sized effects. As a consequence, both severity of TMD and bruxism status are independently associated with cervical impairments. Having TMD is an independent predictor for head/neck pain and cervical impairments. Pain associated with movement tests and tissue mechanosensitivity was found to be an important factor in bruxism.

CONCLUSION

Clinicians need to be aware that signs of cervical movement impairment are not likely to be associated with bruxism, rather they should focus on improving orofacial function and tissue mechanosensitivity.

Validity and reliability of two Smartphone applications to measure the lower and upper cervical spine range of motion in subjects with chronic cervical pain

BACKGROUND

Cervical pain is the biggest musculoskeletal health problem in industrialised countries. There is an important association between this and decrease in range of motion.

OBJECTIVE

Estimate the validity and reliability intra and inter examiner of two Smartphone apps regarding the measurement of lower and upper cervical spine range of motion in subjects with chronic cervical pain.

METHODS

A cross-sectional study was conducted. The sample consisted of 25 subjects with chronic cervical pain. An examiner made a measurement of the range of motion using the CROM device as a gold standard, afterwards, another examiner did the same using a Smartphone, in order to establish validity. After this, the Smartphone examiner and a new examiner simultaneously conducted the intra and inter examiner reliability.

RESULTS

Measurement of the lower and upper cervical spine range show an excellent validity (> 0.75), with an excellent intra and inter reliability (> 0.75) in all movements except flexion of upper cervical spine (0.75-0.65).

CONCLUSION

The two Smartphone applications used in this study showed an excellent validity compared to the CROM. The intra and inter reliability is excellent for all movements, except for the upper cervical spine flexion.

Considerations for Diagnosis and Management of Concussion

Concussion is an ongoing concern for health care providers. The incidence rates continue to be high and the rate of recovery is variable due to potential risk factors. With no valid biomarkers, diagnosis and assessment of concussion remain a clinical challenge. The heterogeneity in presentation following injury provides an additional level of complexity, requiring the screening and evaluation of diverse body systems, including oculomotor, vestibular, autonomic, psychiatric, cervical, and cognitive symptoms. While a few tools, such as the Vestibular/Ocular Motor Screening and Balance Error Scoring System, have been developed specifically for concussion, the vast majority of tests are adapted from other conditions. Further complicating the process is the overlapping and interactive nature of the multiple domains of postconcussion presentation. This commentary illustrates how clinicians can conceptualize the multiple profiles that present following concussion and describes tools that are available to assist with screening and evaluation of each area. The multifaceted nature of concussion warrants broad clinical screening skills and an interdisciplinary approach to management.
