Efficacy of a C1-C2 self-sustained natural apophyseal glide (SNAG) in the management of cervicogenic headache

Contextual Factors-Enriched Standard Care on mechanical neck pain (ContextualizAR trial): Protocol for a randomised controlled trial

BACKGROUND

Understanding the influence of contextual factors (CFs) on interventions for mechanical neck pain (MNP) is essential for evidence-based practice in physical therapy. However, the specific effects and synergies of combining different CFs remain unclear.

OBJECTIVE

The primary purpose of this study will be to determine if a CFs-Enriched Standard Care (SC) approach is an effective treatment for MNP in terms of reducing pain and improving function.

METHODS

This will be an assessor-blinded, 2-group (1:1) randomised clinical trial (RCT) aiming to enrol 94 participants with neck pain persisting for more than 4 weeks. Both groups will undergo 4 weeks of SC twice weekly, following established clinical practice guidelines. In the intervention group, CFs will be enhanced, encompassing the physical, psychological, and social elements inherent in the clinical encounter, based on existing evidence. The primary outcomes will encompass changes in pain and disability after 4 weeks of treatment, with a follow-up reassessment at week 12 post-treatment. Secondary outcomes will include changes in Active Range of Motion, Global Rating of Change, and Satisfaction with treatment. The change between groups after treatment and at the 12-week follow-up will be reported for all outcomes, considering the difference from scores recorded at baseline.

RESULTS

We hypothesise that a 4-week CFs-Enriched SC approach will be superior to SC alone in terms of patient-reported disability and pain, with measurements conducted using the Northwick Park Neck Pain Questionnaire and the Numeric Pain Rating Scale, respectively.

CONCLUSION

This RCT rigorously assesses the effect of purposeful manipulation of CFs during MNP treatment. By elucidating the role of these factors, our findings have the potential to significantly refine clinical practice in managing MNP, thereby enhancing patient care, and advancing the fields of physical therapy and rehabilitation.

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.

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.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

IMPACT

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

Effectiveness of mid thoracic spine mobilization on postural balance and gait ability in subacute stroke patients: A randomized clinical trial

BACKGROUND

Although mulligan sustained natural apophyseal glides (SNAG) and maitland mobilization (MM) are common interventions for musculoskeletal disease, no study has directly compared the effectiveness of mid-thoracic spine mobilization in subacute stroke patients.

OBJECTIVE

To investigate the effects of mid-thoracic spine mobilization (SNAG vs. MM) on postural balance and gait ability in subacute stroke patients.

METHODS

Fifty subacute stroke patients were randomly allocated to the SNAG (n= 17), MM (n= 16), and control (n= 17) groups, each receiving a neuro-developmental therapy program for four successive weeks. The SNAG and MM groups additionally received mid-thoracic spine mobilization (T4∼8). The primary outcome measure was postural sway, and secondary outcome measures included the five times sit-to-stand test (FTSST), functional reach test (FRT), 10-m walk test (10MWT), 6-minute walk test (6MWT) and global rating of change (GRC).

RESULTS

Participants reported no adverse events, and there was no loss to follow-up. The SNAG and MM group patients demonstrated significant improvements (p< 0.05) in postural sway, FTSST, FRT, 10MWT, and 6MWT compared with those in the control group, with no between-group differences.

CONCLUSIONS

Mid-thoracic spine mobilization allows significant improvements in postural balance and gait ability in subacute stroke patients, with no differences between the SNAG and MM techniques.

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.

Effectiveness of therapeutic exercise for the management of cervicogenic headache: A systematic review

OBJECTIVE

The main aim of this systematic review is to evaluate the effectiveness of therapeutic exercise for managing pain and disability in patients with cervicogenic headache (CEH).

METHODS

A protocol for this systematic review was published in PROSPERO (CRD42019122703). PRISMA and AMSTAR2 standards were followed. Based on an extensive systematic search in five databases (EMBASE, MEDLINE, CINHAL, PsychInfo and SportDISCUS) and the CENTRAL trial register, two reviewers carefully and independently assessed, selected results, collected data, rated the risk of bias (RoB) of included studies with the Cochrane risk of bias tool, synthesized the available evidence, and rated it using GRADE methodology.

RESULTS

A total of 12 manuscripts, reporting on 11 studies were included. Most studies showed a high risk of bias (63,63%). Additionally, a great deal of heterogeneity was observed regarding interventions, comparisons, and outcomes and thus, results could not be synthesized in meta-analyses. The quality of the evidence was found to be from low to very low. Significant differences with large effect sizes were found when comparing multimodal exercise vs. control groups on headache outcomes (SMD = 0.73; 95%CI [0.31, 1.14] for headache intensity and SMD = 0.98; 95%CI [0.56, 1.41], for headache frequency).

CONCLUSIONS

Findings indicate that therapeutic exercise may be effective to achieve clinically relevant reductions in headache intensity and frequency as well as disability for patients suffering from cervicogenic headache. However, more high-quality research is needed to gain confidence in this finding and possibly determine optimal types and dosage of therapeutic exercise.

Effectiveness of manual therapy and cervical spine stretching exercises on pain and disability in myofascial temporomandibular disorders accompanied by headaches: a single-center cohort study

BACKGROUND

Previous studies have demonstrated a relationship between headaches and temporomandibular disorders (TMDs). Moreover, recent studies have shown functional, anatomical, and neurological associations between the temporomandibular joint (TMJ) and upper cervical spine. This study aimed to investigate the effectiveness of manual therapy and cervical spine stretching exercises for pain and disability in patients with myofascial TMDs accompanied by headaches.

METHODS

Thirty-four patients recruited from Gyeryong Hospital with headaches and diagnosed with TMDs were randomly assigned to the experimental (n = 17) and control (n = 17) groups. Headache impact was assessed using the Korean Headache Impact Test-6. Masseter myofascial pain was measured using the visual analog scale, and TMJ pressure pain threshold levels were evaluated using an algometer. Neck pain intensity was assessed using the numerical rating scale. Once per week for 10 weeks, the experimental group received cervical spine-focused manual therapy and stretching exercises alongside conservative physical therapy, and the control group received conservative physical therapy alone. Patients were evaluated at baseline and 5 and 10 weeks post-intervention.

RESULTS

After the intervention, the experimental group exhibited significant reductions in the cervical kyphotic angle, Korean Headache Impact Assessment score, neck pain intensity, TMJ pain pressure threshold, Neck Disability Index score, and Jaw Functional Limitation Scale level compared with the control group (p < 0.01).

CONCLUSION

Manual therapy and stretching exercises could help resolve TMDs accompanied by headaches through biomechanical changes in the cervical spine. These findings may guide protocols and clinical trials involving manual therapy that align morphological structures.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

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.

Accuracy of Palpation Procedures for Locating the C1 Transverse Process and Masseter Muscle as Confirmed by Computed Tomography Images

OBJECTIVE

The purpose of this study was to examine the accuracy of palpation methods for locating the transverse processes of the first cervical vertebra and masseter muscle using radiographic images as the gold-standard method and the association between personal characteristics with the observed accuracy.

METHODS

This was a single-blinded, diagnostic accuracy study. Ninety-five participants (49 women, 58 ± 16 years of age) were enrolled in this study. A single examiner palpated the neck and face region of all participants to identify the transverse processes of the first cervical vertebra and masseter muscles bilaterally. In sequence, participants underwent a multislice computed tomography scan for assessment of the superimposed inner body structure. Two radiologists assessed the computed tomography images using the same criteria and were blinded regarding each other's assessment and the anatomic landmarks under investigation. The palpation accuracy was calculated as the proportion of the correctly identified landmarks in the studied sample. The correlation of the palpation outcome (correct = 1; incorrect = 0) with age, sex (male = 1; female = 0), and body mass index was investigated using the point-biserial correlation coefficient.

RESULTS

The right and left transverse processes were correctly located in 76 (80%) and 81 (85%) participants, respectively, and bilaterally in 157 events (83%), as evaluated by the consensus of the 2 radiologists. The masseter muscles were correctly localized bilaterally in 95 of 95 (100%) participants. Body mass showed statistical evidence of a weak, positive correlation with the correct location of the transverse processes of the first cervical vertebra at the right body side (r = .219; 95% confidence interval, 0.018-0.403; P = .033).

CONCLUSION

Palpation methods used in this study accurately identified the location of the first cervical vertebra spinous processes and the masseter muscles.

Efficacy of Physiotherapy Interventions for The Management of Adults With Cervicogenic Headache: A Systematic Review and Meta-Analyses of Randomized Controlled Trials

OBJECTIVE

To update and appraise the efficacy of physiotherapy for adults with cervicogenic headache.

LITERATURE SURVEY

Bibliographic searches were conducted up to September 2021 for randomized controlled trials, assessing the efficacy of physiotherapy interventions for adults with cervicogenic headache, in five databases: CINAHL, PEDro, PubMed, Sage Journals and Wiley Online Library.

METHODS

Data extraction of included trials was conducted by two reviewers according to a standardized extraction form. The PEDro tool and the GRADE approach were used for grading evidence. Results from trials with similar interventions and with similar outcome measures were pooled into separate meta-analyses. A qualitative synthesis was performed for studies that were not pooled into meta-analyses.

SYNTHESIS

Fourteen trials were included. Moderate-certainty evidence indicates that manual therapy significantly reduces headache frequency (MD: -0.93 episodes/week; 95%CI: -1.40 to -0.46; 2 RCTs; n=265) compared to sham manual therapy, and headache frequency (MD: -1.23 episodes/week; 95%CI: -1.55 to -0.91; 3 RCTs; n=126) and intensity (MD: -1.63/10; 95%CI: -2.15 to -1.10; 4 RCTs; n=208) compared to no treatment in the short term. At 12-month follow-up, moderate-certainty evidence indicates that manual therapy did not lead to greater reduction in headache intensity (MD VAS 0-10: -0.12; 95%CI: -0.49 to 0.26; 2 RCTs; n=265) nor frequency (MD: -0.32 episodes/week; 95%CI: -0.91 to 0.28; 2 RCTs; n=265) when compared to a sham manual therapy. In the long-term, in one high quality trial, neck exercise significantly reduces headache intensity compared to no treatment (MD: -1.51/10; 95%CI: -2.52 to -0.50; n=100) or to aerobic exercises in another trial of moderate quality (MD: -1.15/10; 95%CI: -2.1 to -0.20; n=180).

CONCLUSIONS

Manual therapy in the short term and neck exercise in the long term may be efficacious to treat adults with cervicogenic headache. More high quality evidence is needed and future results may change the current conclusions. This article is protected by copyright. All rights reserved.

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

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

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

OBJECTIVE

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

METHODS

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

RESULT

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

CONCLUSION

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

Consensus practice guidelines on interventions for cervical spine (facet) joint pain from a multispecialty international working group

BACKGROUND

The past two decades have witnessed a surge in the use of cervical spine joint procedures including joint injections, nerve blocks and radiofrequency ablation to treat chronic neck pain, yet many aspects of the procedures remain controversial.

METHODS

In August 2020, the American Society of Regional Anesthesia and Pain Medicine and the American Academy of Pain Medicine approved and charged the Cervical Joint Working Group to develop neck pain guidelines. Eighteen stakeholder societies were identified, and formal request-for-participation and member nomination letters were sent to those organizations. Participating entities selected panel members and an ad hoc steering committee selected preliminary questions, which were then revised by the full committee. Each question was assigned to a module composed of 4-5 members, who worked with the Subcommittee Lead and the Committee Chairs on preliminary versions, which were sent to the full committee after revisions. We used a modified Delphi method whereby the questions were sent to the committee en bloc and comments were returned in a non-blinded fashion to the Chairs, who incorporated the comments and sent out revised versions until consensus was reached. Before commencing, it was agreed that a recommendation would be noted with >50% agreement among committee members, but a consensus recommendation would require ≥75% agreement.

RESULTS

Twenty questions were selected, with 100% consensus achieved in committee on 17 topics. Among participating organizations, 14 of 15 that voted approved or supported the guidelines en bloc, with 14 questions being approved with no dissensions or abstentions. Specific questions addressed included the value of clinical presentation and imaging in selecting patients for procedures, whether conservative treatment should be used before injections, whether imaging is necessary for blocks, diagnostic and prognostic value of medial branch blocks and intra-articular joint injections, the effects of sedation and injectate volume on validity, whether facet blocks have therapeutic value, what the ideal cut-off value is for designating a block as positive, how many blocks should be performed before radiofrequency ablation, the orientation of electrodes, whether larger lesions translate into higher success rates, whether stimulation should be used before radiofrequency ablation, how best to mitigate complication risks, if different standards should be applied to clinical practice and trials, and the indications for repeating radiofrequency ablation.

CONCLUSIONS

Cervical medial branch radiofrequency ablation may provide benefit to well-selected individuals, with medial branch blocks being more predictive than intra-articular injections. More stringent selection criteria are likely to improve denervation outcomes, but at the expense of false-negatives (ie, lower overall success rate). Clinical trials should be tailored based on objectives, and selection criteria for some may be more stringent than what is ideal in clinical practice.

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.

The Effect of Adding Dry Needling to Physical Therapy in the Treatment of Cervicogenic Headache: A Randomized Controlled Trial

OBJECTIVE

To compare the long-term effect of adding real or sham dry needling with conventional physiotherapy in cervicogenic headache.

DESIGN

A randomized controlled trial.

SETTING

Physiotherapy Clinic, Rouhani Hospital of Babol University of Medical Sciences, Iran.

SUBJECTS

Sixty-nine patients with cervicogenic headache.

METHODS

Patients were randomly assigned into a control group (n = 23) receiving conventional physical therapy; a dry needling group (n = 23) receiving conventional physical therapy and dry needling on the cervical muscles; placebo needling group (n = 23) receiving conventional physical therapy and superficial dry needling at a point away from the trigger point. The primary outcome was the headache intensity and frequency. Neck disability, deep cervical flexor performance and range of motion were secondary outcomes. Outcomes were assessed immediately after treatment and one, three and six months later.

RESULTS

Sixty-five patients were finally included in the analysis. Headache intensity and neck disability decreased significantly more in the dry needling compared to sham and control groups after treatment and during all follow-ups. The frequency of headaches also reduced more in the dry needling than in control and sham groups, but it did not reach statistical significance. Higher cervical range of motion and enhancement of deep cervical flexors performance was also observed in the dry needling compared to sham and control groups.

CONCLUSION

Dry needling has a positive effect on pain and disability reduction, cervical range of motion and deep cervical flexor muscles performance in patients with cervicogenic headache and active trigger points, although the clinical relevance of the results was small.

Manual therapy in adults with tension-type headache: A systematic review

INTRODUCTION

Tension-type headache is the most common primary headache, with a high prevalence and a considerable socioeconomic impact. Manual physical therapy techniques are widely used in the clinical field to treat the symptoms associated with tension-type headache. This systematic review aims to determine the effectiveness of manual and non-invasive therapies in the treatment of patients with tension-type headache.

DEVELOPMENT

We conducted a systematic review of randomised controlled trials in the following databases: Brain, PubMed, Web of Science, PEDro, Scopus, CINAHL, and Science Direct. Ten randomised controlled trials were included for analysis. According to these studies, manual therapy improves symptoms, increasing patients' well-being and improving the outcome measures analysed.

CONCLUSIONS

Manual therapy has positive effects on pain intensity, pain frequency, disability, overall impact, quality of life, and craniocervical range of motion in adults with tension-type headache. None of the techniques was found to be superior to the others; combining different techniques seems to be the most effective approach.

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.

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). .

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.

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.

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

BACKGROUND

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

OBJECTIVES

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

METHODS

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

RESULTS

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

DISCUSSION AND CONCLUSION

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

Upper cervical spine dysfunction and dizziness

Although various causes of dizziness have been identified, many patients suffer from dizziness of unknown etiology and continue to visit hospitals to resolve their symptoms. Problems that occur in the ligaments or muscles of the upper cervical spine can cause confusion in proprioception. These changes can convey misinformation to the vestibular nucleus, resulting in abnormal reactions that can lead to cervicogenic dizziness (CGD). Though CGD remains controversial, it should be considered while diagnosing patients with dizziness. Understanding CGD can help create treatment strategies for them. This article suggested a relationship between the structure and function of the upper cervical spine and dizziness, and presented evaluations and treatments for the same.

Four-week training involving self-ankle mobilization with movement versus calf muscle stretching in patients with chronic stroke: a randomized controlled study

Background: In self-ankle mobilization with movement (S-MWM) therapy, a strap can be utilized to stabilize the posterior glide of the talus during ankle dorsiflexion movements.Objectives: Our objective was to compare the effects of 4-week self-mobilization with movement (S-MWM) with those of calf muscle stretching (CMS) on ankle dorsiflexion passive range of motion (DF-PROM), gait parameters, and fall risk in patients with chronic stroke with limited ankle dorsiflexion.Methods: Participants were randomized into the S-MWM (n = 19) and CMS groups (n = 19). Both groups received conventional physiotherapy for 30 minutes per session. In addition, S-MWM and CMS techniques were performed 3 times per week for 4 weeks and were performed by the participants themselves. Ankle DF-PROM, gait parameters, and fall risk were measured after 4 weeks of training.Results: After 4 weeks of training, both groups showed significant improvement in all outcome measures (p < .05). Furthermore, ankle DF-PROM, gait parameters (gait speed, cadence, and stride lengths on both sides), and fall risk showed greater improvement in the S-MWM group than in the CMS group (p < .05).Conclusions: This study shows that S-MWM training combined with conventional physiotherapy improved ankle DF-PROM, gait parameters, and fall risk in patients with chronic stroke.

Headache symptom modification: the relevance of appropriate manual therapy assessment and management of a patient with features of migraine and cervicogenic headache - a case report

OBJECTIVES

People who suffer from headache frequently present with multiple headache forms and the precise diagnosis of the dominant headache form can be challenging. This case report describes a headache symptom modification approach in the diagnosis and management of a patient presenting with combined features of chronic migraine and cervicogenic headache (CGH).

METHODS

A 28-year-old female presented with combined features of chronic migraine and CGH diagnosed according to guidelines published by the International Headache Society. Her main complaints were frequent and severe headache along with frequent neck pain and disability. Symptom modification based on the Mulligan Concept was utilized for assessment of musculoskeletal dysfunction associated with headache which identified upper cervical articular impairment. Impairments were also identified in craniocervical muscle control and endurance. Interventions comprised six sessions of Mulligan manual therapy to address cervical spine impairments, exercise for craniocervical control and endurance, as well as patient education.

RESULTS

Headache frequency at 6 months follow up was reduced from 16 to 3 days per month and intensity from 72 to 23 on Visual Analogue Scale. Clinically relevant improvements were also found in headache duration, pressure pain thresholds, medication intake and Headache Activities of Daily Living Index post-treatment and continued up to 6 months follow-up without adverse events.

DISCUSSION

This case report illustrates the use of a manual therapy symptom modification approach in the management of headache. Improvement in headache symptoms and disability suggests that the musculoskeletal impairments and headache symptoms were more a feature of CGH rather than migraine. The mechanisms underlying these changes in symptoms and impairments are discussed.

Physical therapist clinical reasoning and classification inconsistencies in headache disorders: a United States survey

Objective: The purpose of this study was to investigate the decision-making processes of physical therapists relating to evaluation and categorization of patients with headaches, including consistency with criteria proposed by the International Headache Society (IHS).Methods: A national online survey was distributed in cooperation with the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association. Three hypothetical patient case vignettes featuring headache disorders were used as assessment instruments. Additionally, data on physical therapist education, clinical experience, manual therapy training, self-efficacy, and familiarity & consistency with IHS criteria were collected. Physical therapist identification and valuation of clinical features of headache disorders were also examined in the decision-making processes.Results: Among the 384 respondents, 32.3% classified the tension-type headache case consistent with IHS criteria. The cervicogenic and migraine headache cases were classified at 54.8% and 41.7% consistent with IHS categories, respectively. Experienced clinicians and those with formal manual training categorized patient presentations with greater consistency. Clinician familiarity with IHS classification criteria was low with 73.6% collectively somewhat and not familiar, while 26.4% of physical therapists were self-described as very or moderately familiar.Discussion: Clinicians' headache categorization was significantly affected by symptom misattribution and weighting of individual examination findings. Weighting by practitioners of clinical features varied markedly with greatest emphasis being placed on detailed manual examination procedures, including passive intervertebral movements. Inconsistencies in valuation of clinical features in headache categorization suggest a need for further formal education in physical therapy educational curricula and in post-graduate education, including of IHS criteria and classification.Level of Evidence: 2a.

The Chinese Association for the Study of Pain (CASP): Expert Consensus on the Cervicogenic Headache

Cervicogenic headache is a relatively common but unique form of headache, and in China, as well as in several other countries, both diagnosis and a clear evidence-based treatment plan remain controversial. Therefore, the Chinese Association for the Study of Pain organized a meeting of pain management experts and created an expert consensus on the diagnosis and treatment of cervicogenic headache in China. This article summarizes the conclusions of the consensus group regarding the epidemiology, etiology, clinical features, diagnosis, differential diagnosis, treatment, and rehabilitation of cervicogenic headache in China.

Combined use of cervical headache snag and cervical snag half rotation techniques in the treatment of cervicogenic headache

[Purpose] Cervicogenic headache is a major problem in patients with upper cervical dysfunction. However, its physical therapy management is a topic of debate. This study aims to determine the effect of C1-C2 Mulligan sustained natural apophyseal glide mobilizations on cervicogenic headache and associated dizziness. [Participants and Methods] This study included 48 patients with cervicogenic headache, who were randomly assigned to three equal groups: Group A (Headache SNAG), group B (C1-C2 SNAG rotation), and group C (combined). Neck Disability Index was used to examine neck pain intensity and cervicogenic headache symptoms. The 6-item Headache Impact Test scale was used to examine headache severity and its adverse effects on social life and functions. Flexion-Rotation Test was used to assess rotation range of motion at the level of C1-C2 and confirmed by a cervical range of motion device. Dizziness Handicap Inventory scale was used to evaluate dizziness. The evaluation was done pre- and post-treatment and compared between the groups. [Results] Group C showed significant improvement in all variables compared with groups A and B. [Conclusion] Sustained natural apophyseal glide mobilizations used in the study were effective in reducing cervicogenic headache and dizziness in all groups with a greater improvement in the combined group. The use of cervical SNAG mobilizations is encouraged as a noninvasive intervention depending on the therapist's assessment, findings, and clinical reasoning.

Endogenous Neurostimulation and Physiotherapy in Cluster Headache: A Clinical Case

OBJECTIVE

The aim of this paper is to describe the progressive changes of chronic cluster headaches (CHs) in a patient who is being treated by a multimodal approach, using pharmacology, neurostimulation and physiotherapy.

SUBJECT

A male patient, 42 years of age was diagnosed with left-sided refractory chronic CH by a neurologist in November 2009. In June 2014, the patient underwent a surgical intervention in which a bilateral occipital nerve neurostimulator was implanted as a treatment for headache.

METHODS

Case report.

RESULTS

Primary findings included a decreased frequency of CH which lasted up to 2 months and sometimes even without pain. Besides this, there were decreased levels of anxiety, helplessness (PCS subscale) and a decreased impact of headache (HIT-6 scale). Bilateral pressure pain thresholds (PPTs) were improved along with an increase in strength and motor control of the neck muscles. These improvements were present at the conclusion of the treatment and maintained up to 4 months after the treatment.

CONCLUSIONS

A multimodal approach, including pharmacology, neurostimulation and physiotherapy may be beneficial for patients with chronic CHs. Further studies such as case series and clinical trials are needed to confirm these results.

Comparative study of the effects of two inhibitory suboccipital techniques in non-symptomatic subjects with limited cervical mobility

BACKGROUND

Hypomobility on a cervical segment is a frequent finding which is sometimes asymptomatic. The effects of inhibitory suboccipital techniques on cervical mobility have not been evaluated.

OBJECTIVE

To compare the effect on cervical mobility, of pressure maintained suboccipital inhibition manual technique versus a self-treatment using an Occipivot cushion, in asymptomatic subjects with limited mobility assessed by the flexion-rotation test.

METHODS

Before-after randomized uncontrolled trial. Thirty-two subjects were recruited and randomized into two groups: Manual Group and Instrumental Group, receiving a single session of the assigned technique. Upper and overall cervical spine mobility was measured. Subjective sensation during technique application and post-treatment, and number and intensity of headache episodes during the following 15 days after treatment were also registered.

RESULTS

Comparing with the Instrumental Group, the Manual Group showed statistically significant improvements on flexion-rotation test (p< 0.01 to p< 0.03), upper cervical extension (p< 0.01), overall right rotation (p< 0.05) and overall right (p< 0.01) and left (p< 0.01) side-bending.

CONCLUSION

In asymptomatic subjects with limited cervical mobility, pressure maintained suboccipital inhibition manual technique achieves further improvement on cervical range of motion than the technique using the Occipivot cushion.

The C0-C2 axial rotation test: normal values, intra- and inter-rater reliability and correlation with the flexion rotation test in normal subjects

OBJECTIVES

Impairment in upper cervical spine mobility is associated with cervicogenic headache severity and disability. Measures of such mobility include the flexion-rotation test (FRT), which requires full cervical flexion and may be influenced by lower cervical spine dysfunction. The C0-C2 axial rotation test also evaluates upper cervical mobility but normal values and reliability have not been reported. Our objective is to determine normal values, and intra-rater and inter-rater reliability of the C0-C2 axial rotation test.

METHODS

Two therapists independently evaluated the FRT and C0-C2 axial rotation test with an iPhone compass application on 32 asymptomatic subjects with mean age 40.53 (SD 11.64) years on two occasions. Measurement procedures were standardized; and order of testing randomized.

RESULTS

For the FRT and C0-C2 axial rotation test reliability was high (ICC > 0.88). For rater one, Mean range to the left during the FRT and C0-C2 axial rotation test was 45.0° (6.04) and 14.43° (2.94), respectively, while range to the right was 44.6° (6.57) and 15.44° (2.68). For the FRT and C0-C2 axial rotation test the standard error of measurement was at most 2°, while the minimum detectable change was at most 4°. A strong positive correlation exists between the FRT and C0-C2 axial rotation test (r = 0.84, P < 0.01).

DISCUSSION

The range recorded during the C0-C2 axial rotation test and FRT have high levels of reliability when evaluated using an iPhone. The strong correlation between the FRT and C0-C2 axial rotation test indicate that both may be measuring similar constructs, but each test needs to be referenced to normal values.

Effects of a 4-Week Self-Ankle Mobilization with Movement Intervention on Ankle Passive Range of Motion, Balance, Gait, and Activities of Daily Living in Patients with Chronic Stroke: A Randomized Controlled Study

GOAL

To compare the effects of a 4-week self-ankle mobilization with movement training program with those of self-ankle mobilization with movement with a 10° inclined board in patients with chronic stroke.

MATERIALS AND METHODS

A randomized controlled assessor-blind trial was conducted. The patients were randomized into 2 arms. Subjects were 28 chronic stroke patients with hemiplegia. Both arms attended standard rehabilitation therapy for 30 minutes per session. In addition, self-ankle mobilization with movement and self-ankle mobilization with movement with a 10° inclined board trainings were performed 3 times per week for 4 weeks. Ankle dorsiflexion passive range of motion, static balance ability, Berg balance scale, gait parameters (walking speed, cadence, and step length), and activities of daily living were used to assess changes in motor function after training.

FINDINGS

After 4 weeks of training, all dependent variables were significantly improved in both arms as compared with their baseline values. Furthermore, relative to the self-ankle mobilization with movement arm, the self-ankle mobilization with movement with a 10° inclined board arm demonstrated significantly improved ankle dorsiflexion passive range of motion, static balance ability, gait speed, cadence, and affected-side step length.

CONCLUSIONS

Our results support the hypothesis that self-ankle mobilization with movement with a 10° inclined board combined with standard rehabilitation was superior to self-ankle mobilization with movement combined with standard rehabilitation with respect to the improvement in motor function in the patients with chronic stroke.

Three-Dimensional Motion Analysis of the 2nd Cervical Spinous Process at End Range Cervical Rotation in Different Scapular Positions Using 3D Digitizer

OBJECTIVE

The study used a 3D digitizer to determine three-dimensional motion analysis of the 2nd cervical (C2) spinous process at end range cervical rotation with the scapula in different positions.

METHODS

30 healthy adults participated in this study. Different scapula positions were adopted bilaterally and positioned passively at normal resting, depression, adduction, and abduction. Under each scapula position, bilateral end range cervical rotation and displacement of the C2 spinous process were analyzed by a 3D digitizer.

RESULTS

Displacement of the C2 spinous process relative to the occiput was significantly correlated with range of cervical rotation under all scapular positions (p<0.05). However, there were no significant differences between end range cervical rotation and displacement of the C2 spinous process relative to the occiput in any scapular position.

CONCLUSION

These results suggest that measurement of upper cervical mobility using the 3D digitizer is a reliable method that holds promise in the evaluation of people with cervical spine disorders.

Orofacial pain of cervical origin: A case report

BACKGROUND

The etiopathogenesis of orofacial pain remains complex and a number of pain referral patterns for this region have been reported in the literature. The purpose of this report is to describe the assessment and successful clinical management of orofacial pain possibly attributable to cervical origin.

CASE DESCRIPTION

A 55-year-old male teacher with a 3-year history of pain in the right lower jaw, radiating to the ear, consulted our institute for assessment and management. The patient was unsuccessfully treated for dental pain and trigeminal neuralgia. The patient's functioning was grossly limited and the patient was unable to sleep because of severe pain. Current and previous medical and physical examinations revealed no infection, malignancies, or sinusitis. Palpation revealed no temporomandibular disorder, tenderness or myofascial trigger points. Examination of the cervical range of motion showed a reduction in rotation to the right side. The patient was treated for upper cervical joint dysfunction involving mobilization of the first three cervical vertebrae and motor control exercises. The patient had an almost complete resolution of symptoms and reported significant improvement in the Patient Specific Functional Scale (PSFS) and the Global Rating of Change (GRC) scale.

CONCLUSION

This case study demonstrates the importance of considering, assessing and treating the cervical spine as a possible source of orofacial pain, and the positive role of cervical mobilization on these disorders.

The Effect of Mulligan Mobilization Technique in Older Adults with Neck Pain: A Randomized Controlled, Double-Blind Study

Background

The purpose of this study was to examine the effect of Mulligan mobilization technique (MMT) on pain, range of motion (ROM), functional level, kinesiophobia, depression, and quality of life (QoL) in older adults with neck pain (NP).

Methods

Forty-two older adults with NP were included in the study, and they were randomly divided into two groups: traditional physiotherapy (TP) group and traditional physiotherapy-Mulligan mobilization (TPMM) group. Treatment program was scheduled for 10 sessions. Participants were assessed in terms of pain, ROM, functional level, kinesiophobia, depression, and QoL both pre- and posttreatment.

Results

Pain, ROM, functional level, kinesiophobia, depression, and QoL improved in both groups following treatment (p < 0.05). When comparing effects of these two treatment programs, it was observed that the TPMM group had a better outcome (p < 0.05) in terms of ROM, kinesiophobia, depression, and QoL.

Conclusion

In older adults with NP, MMT has been found to have significant effects on pain, ROM, functional level, kinesiophobia, depression, and QoL as long as it is performed by a specialist. "This trial is registered with NCT03507907".
