Headache management in traumatic brain injury.

Traumatic brain injury (TBI) is estimated to rank as the third most important disease burden worldwide. About 60% of the survivors develop chronic headaches and visual symptoms, and the long-term management of headaches in these patients is controversial. Importantly, the care pathway of most patients is fragmented, complicating conclusive headache management. Here we review the epidemiology and aetiology of post traumatic headaches (PTH), discuss the diagnostic work up and summarise the acute and long-term management.

The Effects of Cervical Mobilization with Clinical Pilates Exercises on Pain, Muscle Stiffness and Head and Neck Blood Flow in Cervicogenic Headache: Randomized Controlled Trial.

Background and Objectives: Physiotherapy approaches are used to eliminate the problems caused by cervicogenic headache (CHA), known as secondary headache associated with the structures of the upper cervical region. This study aimed to investigate the effects of cervical mobilization (CM) with clinical Pilates exercises (CPE) on pain, muscle stiffness and head-neck blood flow in CGH. Materials and Methods: A total of 25 patients participated in this randomized controlled study and were randomized into either the CM group or the CM+CPE group. All treatment methods were applied 3 days a week for 6 weeks. The outcome measure was headache intensity and frequency, the number of analgesics, muscle stiffness and vertebral artery (VA) and internal carotid artery (ICA) blood flow. Headache intensity was measured by a visual analogue scale, muscle stiffness by a myotonometer and blood flow by Doppler US. Evaluations were repeated after 6 weeks of treatment. Within-group comparisons were made by the Wilcoxon signed rank test, and between-group comparisons were made by the Mann-Whitney U test. Results: After treatments in the two groups, headache intensity and frequency and the number of analgesics decreased, the muscle stiffness of the suboccipital, upper trapezius and sternocleidomastoid (SCM) muscles decreased, and the blood flow of the ICA and VA increased (p < 0.05). There was a significant difference between the groups in terms of headache intensity (p = 0.025) and muscle stiffness in SKM (p = 0.044) in favor of the CM+CPE group. Conclusions: Non-pharmacological treatment approaches have an important role in CHA related to the upper cervical region. This study suggests that it would be beneficial to add CM in combination with CPE to the non-pharmacological treatment of patients with CHA.

Mulligan manual therapy added to exercise improves headache frequency, intensity and disability more than exercise alone in people with cervicogenic headache: a randomised trial.

QUESTION: What is the effect of a 4-week regimen of Mulligan manual therapy (MMT) plus exercise compared with exercise alone for managing cervicogenic headache? Is MMT plus exercise more effective than sham MMT plus exercise? Are any benefits maintained at 26 weeks of follow-up? DESIGN: A three-armed, parallel-group, randomised clinical trial with concealed allocation, blinded assessment of some outcomes and intention-to-treat analysis. PARTICIPANTS: Ninety-nine people with cervicogenic headache as per International Classification of Headache Disorders (ICHD-3). INTERVENTIONS: Participants were randomly allocated to 4 weeks of: MMT with exercise, sham MMT with exercise or exercise alone. OUTCOME MEASURES: The primary outcome was headache frequency. Secondary outcomes were headache intensity, headache duration, medication intake, headache-related disability, upper cervical rotation range of motion, pressure pain thresholds and patient satisfaction. Outcome measures were collected at baseline and at 4, 13 and 26 weeks. RESULTS: MMT plus exercise reduced headache frequency more than exercise alone immediately after the intervention (MD between groups in change from baseline: 2 days/month, 95% CI 2 to 3) and this effect was still evident at 26 weeks (MD 4 days, 95% CI 3 to 4). There were also benefits across all time points in several secondary outcomes: headache intensity, headache duration, headache-related disability, upper cervical rotation and patient satisfaction. Pressure pain thresholds showed benefits at all time points at the zygapophyseal joint and suboccipital areas but not at the upper trapezius. The outcomes in the sham MMT with exercise group were very similar to those of the exercise alone group. CONCLUSIONS: In people with cervicogenic headache, adding MMT to exercise improved: headache frequency, intensity and duration; headache-related disability; upper cervical rotation; and patient satisfaction. These benefits were not due to placebo effects. TRIAL REGISTRATION: CTRI/2019/06/019506.

Meta-Analysis of Acupuncture Treatment for Cervicogenic Headache.

OBJECTIVE: To analyze and evaluate the clinical effect of acupuncture on cervicogenic headache (CEH), and provide evidence-based basis for clinical selection of acupuncture for CEH. METHODS: Databases including China Knowledge Network, Wanfang, VIP Chinese sci-tech journals, Chinese Biomedical, and PubMed were searched to collect clinical randomized controlled trials on the effectiveness of acupuncture in the treatment of CEH until November 2023. Statistical analysis was performed using the RevMan 5.4.1 software, and heterogeneity was assessed using the Q test (P value), allowing for the calculation of the combined effect odds ratio through either the fixed or random-effect model. Sensitivity analysis will be conducted by excluding articles with the highest weight, while the validity of the literature will be evaluated through the creation of a funnel plot to identify any potential biases. RESULTS: A total of 400 articles were retrieved, and eventually, 20 clinical randomized controlled trials were included in the analysis. Comparing with control, acupuncture exhibited a higher total effective rate in treating CEH. The cure rate was also higher in the experimental group, and improvements in short-term and long-term visual analogue scale scores outcomes were significantly greater than those in the control group. The quality-of-life scores were higher in CEH patients treated with acupuncture. Sensitivity analysis confirmed the stability and reliability of the pooled effect size results. The results of the funnel plot indicated the presence of publication bias. CONCLUSIONS: Acupuncture treatment is effective for CEH relief and worthy of clinical application.

Can Long-Term Outcomes of Posttraumatic Headache be Predicted?

PURPOSE OF REVIEW: Headache is one of the most common symptoms of traumatic brain injury, and it is more common in patients with mild, rather than moderate or severe, traumatic brain injury. Posttraumatic headache can be the most persistent symptom of traumatic brain injury. In this article, we review the current understanding of posttraumatic headache, summarize the current knowledge of its pathophysiology and treatment, and review the research regarding predictors of long-term outcomes. RECENT FINDINGS: To date, posttraumatic headache has been treated based on the semiology of the primary headache disorder that it most resembles, but the pathophysiology is likely to be different, and the long-term prognosis differs as well. No models exist to predict long-term outcomes, and few studies have highlighted risk factors for the development of acute and persistent posttraumatic headaches. Further research is needed to elucidate the pathophysiology and identify specific treatments for posttraumatic headache to be able to predict long-term outcomes. In addition, the effect of managing comorbid traumatic brain injury symptoms on posttraumatic headache management should be further studied. Posttraumatic headache can be a persistent symptom of traumatic brain injury, especially mild traumatic brain injury. It has traditionally been treated based on the semiology of the primary headache disorder it most closely resembles, but further research is needed to elucidate the pathophysiology of posttraumatic headache and determine risk factors to better predict long-term outcomes.

Myofascial Release for the Treatment of Tension-Type, Cervicogenic Headache or Migraine: A Systematic Review and Meta-Analysis.

Objective: To assess the effectiveness of myofascial release (MFR) techniques on the intensity of headache pain and associated disability in patients with tension-type headache (TTH), cervicogenic headache (CGH), or migraine. Design: A systematic review and meta-analysis. Methods: Eight databases were searched on September 15, 2023, including PubMed, Scopus, Web of Science, CINAHL, Cochrane Library, Embase, CNKI, and Wanfang Database. The risk of bias was evaluated utilizing the Cochrane Risk of Bias 2 (RoB 2) tool. Results: Pooled results showed that MFR intervention significantly reduces pain intensity [SMD = -2.01, 95% CI (-2.98, -1.03), I2 = 90%, P < 0.001] and improves disability [SMD = -1.3, 95% CI (-1.82, -0.79), I2 = 74%, P < 0.001]. Subgroup analysis based on the type of headache revealed significant reductions in pain intensity for CGH [SMD = -2.01, 95% CI (-2.73, -1.29), I2 = 63%, P < 0.001], TTH [SMD = -0.86, 95% CI (-1.52, -0.20), I2 = 50%, P=0.01] and migraine [SMD = -6.52, 95% CI (-8.15, -4.89), P < 0.001] and in disability for CGH [SMD = -1.45, 95% CI (-2.07, -0.83), I2 = 0%, P < 0.001]; TTH [SMD = -0.98, 95% CI (-1.32, -0.65), I2 = 0%, P < 0.001] but not migraine [SMD = -2.44, 95% CI (-6.04, 1.16), I2 = 97%, P=0.18]. Conclusion: The meta-analysis results indicate that MFR intervention can significantly alleviate pain and disability in TTH and CGH. For migraine, however, the results were inconsistent, and there was only moderate quality evidence of disability improvement for TTH and CGH. In contrast, the quality of other evidence was low or very low.

Cervicogenic Headaches: A Literature Review and Proposed Multifaceted Approach to Diagnosis and Management.

Cervicogenic headaches are a secondary headache disorder attributable to cervical spine dysfunction resulting in head pain with or without neck pain. Diagnosis of this condition has been complicated by varied clinical presentations, causations, and differing diagnostic criteria. In this article, we aim to clarify the approach to diagnosing cervicogenic headaches by providing an overview of cervicogenic headaches, clinical case examples, and a practical diagnostic algorithm based on the most current criteria. A standardized approach will aid in confirmation of the diagnosis of cervicogenic headaches and facilitate further research into this condition.

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

BACKGROUND: There is ample evidence supporting the use of different manipulative therapy techniques for Cervicogenic Headache (CgH). However, no technique can be singled as the best available treatment for patients with CgH. Therefore, the objective of the study is to find and compare the clinical effects of cervical spine over thoracic spine manipulation and conventional physiotherapy in patients with CgH. DESIGN, SETTING, AND PARTICIPANTS: It is a prospective, randomized controlled study conducted between July 2020 and January 2023 at the University hospital. N = 96 eligible patients with CgH were selected based on selection criteria and they were divided into cervical spine manipulation (CSM; n = 32), thoracic spine manipulation (TSM; n = 32) and conventional physiotherapy (CPT; n = 32) groups, and received the respective treatment for four weeks. Primary (CgH frequency) and secondary CgH pain intensity, CgH disability, neck pain frequency, neck pain intensity, neck pain threshold, cervical flexion rotation test (CFRT), neck disability index (NDI) and quality of life (QoL) scores were measured. The effects of treatment at various intervals were analyzed using a 3 × 4 linear mixed model analysis (LMM), with treatment group (cervical spine manipulation, thoracic spine manipulation, and conventional physiotherapy) and time intervals (baseline, 4 weeks, 8 weeks, and 6 months), and the statistical significance level was set at P < 0.05. RESULTS: The reports of the CSM, TSM and CPT groups were compared between the groups. Four weeks following treatment CSM group showed more significant changes in primary (CgH frequency) and secondary (CgH pain intensity, CgH disability, neck pain frequency, pain intensity, pain threshold, CFRT, NDI and QoL) than the TSM and CPT groups (p = 0.001). The same gradual improvement was seen in the CSM group when compared to TSM and CPT groups (p = 0.001) in the above variables at 8 weeks and 6 months follow-up. CONCLUSION: The reports of the current randomized clinical study found that CSM resulted in significantly better improvements in pain parameters (intensity, frequency and threshold) functional disability and quality of life in patients with CgH than thoracic spine manipulation and conventional physiotherapy. TRIAL REGISTRATION: Clinical trial registration: CTRI/2020/06/026092 trial was registered prospectively on 24/06/2020.

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.

Effects of sustained natural apophyseal glides versus rocabado 6 × 6 program in subjects with cervicogenic headache.

BACKGROUND: Cervicogenic headache is designated as the most common type of secondary headache that results from conditions affecting the neck's bony components, muscles, and intervertebral discs rather than the head itself. OBJECTIVE: The purpose was to determine the effects of Sustained Natural Apophyseal Glides (SNAGs) versus the Rocabado 6 × 6 program in subjects with cervicogenic headaches. METHODS: This study was a randomized clinical trial. The sample size was 38, and participants aged 20-60 years (mean age 40.22 ± 9.66) suffering from cervicogenic headaches were randomly allocated using the lottery method into two groups with 19 participants in each group. Assessment of subjects was done before starting treatment and by the end of the 8th week for all the variables. Outcome measures were the Neck Disability Index (NDI), 6-item Headache Impact Test (HIT-6), Flexion-Rotation test (FRT) to assess the rotation range of motion at the level of C1-C2 (goniometer) and the Numeric Pain Rating Scale (NPRS) for the intensity of pain. Data analysis was done by SPSS (IBM) 25. To check the normality of the data the Shapiro-Wilk test was used. RESULTS: In the Shapiro-Wilk test p-value of all the testing variables i.e. NDI, HIT-6 score, FRT and NPRS was > 0.05, data was normally distributed and parametric tests were used. Group A showed a considerable improvement (p < 0.05) in all variables compared to Group B, while within-group analysis of both groups shows that all outcome measures show significant results (p < 0.05). CONCLUSION: It was concluded that both SNAGs and Rocabado's 6 × 6 exercises were effective for the treatment of cervicogenic headache but the effects of headache SNAG were superior and produced more improvement in intensity of headache, disability, frequency of headache, duration of headache as compared to Rocabado 6 × 6 exercises. TRIAL REGISTRATION NUMBER: This study was registered at ClinicalTrials.gov ID: NCT05865808 on date 19/05/2023.

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.

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.

Efficacy and safety of acupuncture in the treatment of post-traumatic headache secondary to mild traumatic brain injury: A systematic evaluation and meta-analysis protocol of randomized controlled trials.

INTRODUCTION: Post-traumatic headache secondary to mild traumatic brain injury in patients has become an important factor in their prognosis. Due to the lack of effective pharmacological treatments, non-pharmacological interventions such as acupuncture are considered to have greater potential. However, the efficacy and safety of acupuncture treatment have not been clearly demonstrated. The purpose of this meta-analysis protocol is to investigate the effectiveness and safety of acupuncture in the treatment of headache secondary to mild traumatic brain injury. METHODS AND ANALYSIS: Seven English and Chinese databases will be selected and searched according to their respective search methods, spanning the period from database creation to April 2022, and the languages will be limited to English and Chinese. Only randomized controlled trials will be included. Study selection, data collection, and risk of bias control will be performed by two independent investigators. Any disagreements will be referred to a third independent investigator for decision and documentation. Revman software will be used to complete our meta-analysis, and risk of bias assessment, subgroup analysis, and sensitivity analysis will be performed to correct the results. Finally we will assess the reliability of our final results using the Recommended Guidelines Development Tool for Assessment. ETHICS AND DISSEMINATION: All data for this study will be obtained from published journals, so no ethical review will be required. The completed review will be published in a peer-reviewed journal and the findings will be further disseminated through presentation at an appropriate forum or conference.

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.

The Role of Manual Therapies in the Treatment of Headache Disorders.

PURPOSE OF REVIEW: A comprehensive headache treatment plan typically requires both medication and non-medication treatment strategies. Manual therapies offer another therapeutic approach to headache treatment. This article reviews the evidence for manual therapies in the treatment of headache disorders. RECENT FINDINGS: Current evidence shows potential benefit from myofascial trigger point injections, myofascial release, and massage for the treatment of various headache types. There is also evidence for strain counterstrain technique, ischemic compression, and spinal manipulative therapies for cervicogenic headache. Although larger randomized clinical trials are necessary for many of these modalities, recent findings show that manual therapies could be an important tool for the treatment of some headache disorders.

Cervicogenic headache.

INTRODUCTION: Cervicogenic headache, first proposed as a distinct headache in 1983, is a secondary headache to a primary cervical musculoskeletal disorder. Research into physical impairments was integral to clinical diagnosis and to develop and test research informed conservative management as the first line approach. PURPOSE: This narrative presents an overview of the body of cervicogenic headache research from our laboratory which was undertaken in the context of a broad program of research into neck pain disorders. IMPLICATIONS: Early research validated manual examination of the upper cervical segments against anaesthetic nerve blocks, which was vital to clinical diagnosis of cervicogenic headache. Further studies identified reduced cervical motion, altered motor control of the neck flexors, reduced strength of flexor and extensor muscles, and occasional presentation of mechanosensitivity of the upper cervical dura. Single measures are variable and not reliable in diagnosis. We proved that a pattern of reduced motion, upper cervical joint signs and impaired deep neck flexor function accurately identified cervicogenic headache and differentiated it from migraine and tension-type headache. The pattern was validated against placebo controlled diagnostic nerve blocks. A large multicentre clinical trial determined that a combined program of manipulative therapy and motor control exercise is effective in the management of cervicogenic headache and outcomes are maintained in the long term. More specific research into cervical related sensorimotor controlled is warranted in cervicogenic headache. Further adequately powered clinical trials of current research informed multimodal programs are advocated to further strengthen the evidence base for conservative management of cervicogenic headache.

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

BACKGROUND/PURPOSE: Headaches are among the most common complaints requiring medical care, and annual expenditures for this condition are estimated to be 14 billion US dollars. The International Headache Society (IHS) describes cervicogenic headache (CGH) as a secondary type of headache emanating from the cervical spine which may be referred to one or more regions of the head and/or face. Mechanical Diagnosis and Therapy (MDT) is an approach shown to be effective in the management of spinal musculoskeletal disorders; however, there is limited evidence as to its efficacy in the management of CGH. The purpose of this case series was to examine the MDT approach in the assessment, classification, and management of a sample of patients experiencing cervicogenic headache. CASE DESCRIPTION: This study was a prospective case series. Following IRB approval, 15 patients meeting the study inclusion criteria were recruited from a hospital-based outpatient physical therapy clinic. All subjects received a physical therapy examination by a Diploma trained MDT clinician which included but was not limited to patient self-report forms and the testing of repeated end range movements. The Numerical Pain Rating Scale (NPRS), Neck Disability Index (NDI), Headache Disability Index (HDI), Yellow Flag Risk Form (YFRF), Cervical Flexion Rotation Test (CFRT), and the Craniocervical Flexion Test (CCFT) were administered at the initial visit, 5th visit, and 10th visit or discharge, whichever occurred first. The NPRS, NDI, and HDI were re-administered at a 3 month follow up. Following the initial examination, patients were classified into the MDT categories of derangement, dysfunction, postural, or 'other' and then received intervention based on directional preference. OUTCOMES: Fifteen subjects (mean age, 45.9 years; F = 11, M = 4; symptom duration, 44.3 months; average visits, 8.8) received an examination and intervention and completed follow-up outcome measures. Based on MDT classification criteria, all 15 subjects in this case series were classified as derangements. A non-parametric Friedman test of Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation differences among repeated measures was conducted on all outcome measures revealing statistically significant improvements in NPRS (p < .01), NDI(p < .01), and HDI (p < .01) scores at visit 10 and 3 month follow up. The mean change scores exceeded the minimal clinical important difference (MCID) for NPRS (4.2), NDI (7.6), and HDI (28.5). CCFT scores improved significantly from the initial examination to visit 5 (p < .01) and YFRF scores improved significantly between visits 5 and 10 (p < .01). DISCUSSION/CONCLUSION: The diagnosis of CGH is difficult to determine based on pathoanatomical assessment. This case series suggests that the patient's response to repeated end range movements may indicate a directional preference for manual procedures and exercises which may be used in management of musculoskeletal conditions such as CGH.

The cervical spine in tension type headache.

INTRODUCTION: The concept that headaches may originate in the cervical spine has been discussed over decades and is still a matter of debate. The cervical spine has been traditionally linked to cervicogenic headache; however, current evidence supports the presence of cervical musculoskeletal dysfunctions also in tension-type headache. PURPOSE: This position paper discusses the most updated clinical and evidence-based data about the cervical spine in tension-type headache. IMPLICATIONS: Subjects with tension-type headache exhibit concomitant neck pain, cervical spine sensitivity, forward head posture, limited cervical range of motion, positive flexion-rotation test and also cervical motor control disturbances. In addition, the referred pain elicited by manual examination of the upper cervical joints and muscle trigger points reproduces the pain pattern in tension-type headache. Current data supports that the cervical spine can be also involved in tension-type headache, and not just in cervicogenic headache. Several physical therapies including upper cervical spine mobilization or manipulation, soft tissue interventions (including dry needling) and exercises targeting the cervical spine are proposed for managing tension-type headache; however, the effectiveness of these interventions depends on a proper clinical reasoning since not all will be equally effective for all individuals with tension-type headache. Based on current evidence, we propose to use the terms cervical "component" and cervical "source" when discussing about headache. In such a scenario, in cervicogenic headache the neck can be the cause (source) of the headache whereas in tension-type headache the neck will have a component on the pain pattern, but it will be not the cause since it is a primary headache.

[Analysis of the efficacy and safety of coblation and pulsed radiofrequency in the treatment of cervicogenic headache].

Objective: To explore the efficacy and safety of coblation and pulsed radiofrequency on cervicogenic headache (CEH). Methods: A total of 118 patients with CEH who underwent coblation or pulsed radiofrequency in the Department of Pain Management at Xuanwu Hospital, Capital Medical University from August 2018 to June 2020 was retrospectively collected. Patients were divided into the coblation group (n=64) and the pulsed radiofrequency group (n=54) according to different surgical methods. In the coblation group, there were 14 males and 50 females, aged 29-65 (49.8±10.2) years, while in the pulse radiofrequency group, there were 24 males and 30 females, aged 18-65 (41.7±14.8) years. Visual analogue scale (VAS) score, postoperative numbness in the affected areas and other complications were recorded and compared between the two groups at preoperative 3 d, and 1 month, 3 months and 6 months postoperatively. Results: The VAS score of the coblation group was (7.16±0.91), (3.67±1.13), (1.59±0.91), (1.66±0.84) and (1.56±0.90) before operation, and 3 days, 1 month, 3 months and 6 months after surgery. Likewise, the VAS score of the pulsed radiofrequency group was (7.01±0.78), (1.58±0.88), (1.57±0.94), (3.71±1.08) and (6.92±0.83) at the aforementioned time points. There were statistically significant differences of VAS scores between the coblation group and the pulsed radiofrequency group at 3 days, 3 months and 6 months postoperatively (all P<0.001). Intra-group comparison revealed that VAS scores in the coblation group were significantly lower than those before surgery at all time points after surgery (all P<0.001), while VAS scores in the pulsed radiofrequency group were significantly decreased at 3 days, 1 month and 3 months after surgery (P<0.001). The incidence of numbness was 72% (46/64), 61% (39/64), 6% (4/64) and 3% (2/62) in the coblation group and 7% (4/54), 7% (4/54), 2% (1/54) and 0 (0/54) in the pulsed radiofrequency group, respectively. At 3 days and 1 month after surgery, the incidence of numbness in the coblation group was higher than those in the pulsed radiofrequency group (both P<0.001). In the coblation group, one patient developed pharyngeal discomfort 3 days after surgery, which disappeared spontaneously 1 week after surgery without special treatment. One patient developed vertigo after getting up in the morning at 3 days postoperatively, and the possibility of transient cerebral ischemia was considered. In the pulsed radiofrequency group, one patient developed nausea and vomiting after operation, but spontaneous remission was observed after one hour without special treatment. Conclusions: Both coblation and pulsed radiofrequency are effective and safe in the treatment of CEH. But the VAS scores at 3 and 6 months after coblation is significantly lower than those of pulsed radiofrequency ablation group, and the efficacy is better in those undergoing coblation.

Developing multivariable models for predicting headache improvement in patients with acute post-traumatic headache attributed to mild traumatic brain injury: A preliminary study.

OBJECTIVES/BACKGROUND: Post-traumatic headache (PTH) is a common symptom after mild traumatic brain injury (mTBI). Although there have been several studies that have used clinical features of PTH to attempt to predict headache recovery, currently no accurate methods exist for predicting individuals' improvement from acute PTH. This study investigated the utility of clinical questionnaires for predicting (i) headache improvement at 3 and 6 months, and (ii) headache trajectories over the first 3 months. METHODS: We conducted a clinic-based observational longitudinal study of patients with acute PTH who completed a battery of clinical questionnaires within 0-59 days post-mTBI. The battery included headache history, symptom evaluation, cognitive tests, psychological tests, and scales assessing photosensitivity, hyperacusis, insomnia, cutaneous allodynia, and substance use. Each participant completed a web-based headache diary, which was used to determine headache improvement. RESULTS: Thirty-seven participants with acute PTH (mean age = 42.7, standard deviation [SD] = 12.0; 25 females/12 males) completed questionnaires at an average of 21.7 (SD = 13.1) days post-mTBI. The classification of headache improvement or non-improvement at 3 and 6 months achieved cross-validation area under the curve (AUC) of 0.72 (95% confidence interval [CI] 0.55 to 0.89) and 0.84 (95% CI 0.66 to 1.00). Sub-models trained using only the top five features still achieved 0.72 (95% CI 0.55 to 0.90) and 0.77 (95% CI 0.52 to 1.00) AUC. The top five contributing features were from three questionnaires: Pain Catastrophizing Scale total score and helplessness sub-domain score; Sports Concussion Assessment Tool Symptom Evaluation total score and number of symptoms; and the State-Trait Anxiety Inventory score. The functional regression model achieved R = 0.64 for modeling headache trajectory over the first 3 months. CONCLUSION: Questionnaires completed following mTBI have good utility for predicting headache improvement at 3 and 6 months in the future as well as the evolving headache trajectory. Reducing the battery to only three questionnaires, which assess post-concussive symptom load and biopsychosocialecologic factors, was helpful to determine a reasonable prediction accuracy for headache improvement.
