[more] © 2019 Elsevier Ltd Aims: Neck pain is common in migraine and tension type headache (TTH). This review aimed to examine the evidence for cervical musculoskeletal impairments in these headaches. Methods: Databases PubMed (Medline), EMBASE, CINAHL, SCOPUS, and Web of Science were searched from inception to December 2018. Observational studies using a comparator group were included. Risk of bias was assessed using the Appraisal tool for Cross-Sectional Studies. Results were pooled using random effects meta-analysis. Level of evidence for each outcome was assigned based on risk of bias, consistency of results and magnitude of difference between participants with headache and controls. (PROSPERO registration: CRD42018083683). Results: Of 48 studies included, the majority were rated moderate risk of bias due to possible confounding influences. In total, 17 cervical outcomes were assessed, with confidence in findings ranging from very low to moderate levels. Compared to controls, participants with TTH had greater forward head posture (FHP) (MD = -6.18°, 95% CI [-8.18°, -4.18°]) and less cervical range of motion (ROM) (greatest difference transverse plane MD = -15.0°, 95% CI [-27.7°, -2.3°]. Participants with migraine demonstrated minimally reduced cervical ROM (greatest difference sagittal plane MD = -5.4°, 95% CI [-9.9°, -0.9°]. No differences presented in head posture, strength, craniocervical flexion test performance or joint position error between migraineurs and controls. Conclusions: TTH presented with more findings of cervical musculoskeletal impairments than migraine however levels of confidence in findings were low. Future studies should differentiate episodic from chronic headache, identify coexisting musculoskeletal cervical disorders, and describe neck pain behaviour in headache.

[more] © 2017 National Stroke Association Background Cervical artery dissection (CAD) is a leading cause of stroke among middle-aged adults, but the etiology is unclear. Some reports of seasonal variation in CAD incidence have been suggested but may reflect extreme climatic conditions. Seasonal variation may implicate more transient seasonal causes such as proinflammatory or hypercoagulable states. This study aimed to assess whether CAD incidence varied with season between UK and Australian sites. Also, this study aimed to determine whether there was a different pattern of seasonal variation between arteries (carotid and vertebral) and any association between CAD incidence and clinical factors. Methods This was a retrospective observational study of patients older than 18 years with radiological diagnosis of internal carotid or vertebral arterial dissection, from sites in Australia and the UK. Clinical variables were compared between autumn-winter and spring-summer and site of dissection. Results A total of 133 CAD cases were documented in Australia and 242 in the UK. There was a seasonal pattern to CAD incidence in countries in both the northern and the southern hemispheres, with a trend for dissection to occur more commonly in autumn, winter, and spring than in summer (incidence rate ratios [IRR] 1.4-1.5, P¿<¿.05). CAD counts were also slightly higher in internal carotid than in vertebral artery (IRRs 1.168, 1.43, and 1.127, respectively). Neither systolic blood pressure nor pulse pressure was significantly associated with CAD counts. Conclusions CAD occurs more commonly in cooler months regardless of geographical location, suggesting transient seasonal causes may be important in the pathophysiology. This effect was slightly higher in internal carotid than in vertebral artery, suggesting differing trigger mechanisms between dissection sites.

[more] © 2015 Elsevier Ltd. Introduction: Cervical arterial dissection (CAD) is a common cause of stroke in young people under 55 years. It can occur spontaneously or subsequent to minor trauma or infection. The incidence is difficult to determine accurately as not all CAD progress to stroke. CAD is the most catastrophic adverse event associated with cervical manipulative therapy but it is rare. Early features of CAD can mimic a painful musculoskeletal presentation and a patient may present for treatment of neck pain and headache with a dissection in progress. Whether the manipulative technique is responsible for dissection or whether the diagnosis of CAD has been missed is unclear. Identification of individuals at risk, or early recognition of CAD could help expedite medical intervention and avoid inappropriate treatment. Purpose: The aims of this masterclass are to outline current research into the pathophysiology, aetiology and clinical presentation of CAD, to place the risk in context in a manipulative therapy setting and to discuss its possible clinical recognition. Implications: For those patients presenting with recent onset, moderate to severe unusual headache or neck pain, clinicians should perform a careful history, in particular questioning about recent exposure to head/neck trauma or neck strain. Cardiovascular factors may not be particularly useful indicators of risk of dissection. Clinicians should also be alert to reports of transient neurological dysfunction such as visual disturbance and balance deficits, arm paraesthesia and speech deficits, as these may be subtle. If clinicians suspect arterial dissection is in progress patients should be urgently referred for medical evaluation.

[more] Copyright ©2015 Journal of Orthopaedic & Sports Physical Therapy®. All rights reserved. STUDY DESIGN: Cross-sectional case-control study. OBJECTIVES: To identify risk factors and clinical presentation of individuals with cervical arterial dissection. BACKGROUND: Cervical arterial dissection is a common cause of stroke in young people and has in rare cases been associated with cervical manipulative therapy. The mechanism is considered to involve pre-existing arterial susceptibility and a precipitating event, such as minor trauma. Identification of individuals at risk or early recognition of a dissection in progress could help expedite medical intervention and avoid inappropriate treatment. METHODS: Participants were individuals 55 years of age or younger from the Hunter region of New South Wales, Australia with radiologically confirmed vertebral or internal carotid artery dissection and an age- and sex-matched comparison group. Participants were interviewed about risk factors, preceding events, and clinical features of their stroke. Physical examination of joint mobility and soft tissue compliance was undertaken. RESULTS: Twenty-four participants with cervical arterial dissection and 21 matched comparisons with ischemic stroke but not dissection were included in the study. Seventeen (71%) of the 24 participants with dissection reported a recent history of minor mechanical neck trauma or strain, with 4 of these 17 reporting recent neck manipulative therapy treatment. Cardiovascular risk factors were uncommon, with the exception of diagnosed migraine. Among the participants with dissection, 67% reported transient ischemic features in the month prior to their admission for dissection. CONCLUSION: Recent minor mechanical trauma or strain to the head or neck appears to be associated with cervical arterial dissection. General cardiovascular risk factors, with the exception of migraine, were not important risk factors for dissection in this cohort. Preceding transient neurological symptoms appear to occur commonly and may assist in the identification of this serious pathology.
