Conservative physical therapy management for the treatment of cervicogenic headache: a systematic review

The utilization of dry needling and an upper extremity exercise program for individuals with cervicogenic headaches: A pilot study

OBJECTIVE

To investigate whether a combination of dry-needling treatments and upper extremity neuromuscular reeducation exercises can significantly improve neck pain and/or headache-related disability, joint position error, cervical range of motion, and pain pressure threshold in individuals suffering from cervicogenic headache (CGH).

METHODS

This study is a quasi-experimental design. Seven participants met the inclusion criteria and received dry needling to three muscles that reproduced the participant's headache symptoms and completed the Neck Disability Index (NDI), Headache Disability Inventory (HDI), Visual Analog Scale (VAS), and Numeric Pain Rating Scale (NPRS). Participants performed an exercise regimen designed to address strength and mobility of cervical and scapulothoracic musculature.

RESULTS

There were significant improvements seen in cervical range of motion and neck pain-related disability (NDI) during the 4-week treatment period.

CONCLUSION

Dry needling and neuromuscular re-education (NMR) exercises could be effective components of treatment for individuals suffering from CGH to reduce disability and pain.

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 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.

Spinal manipulation and adverse event reporting in the pregnant patient limits estimation of relative risk: a narrative review

OBJECTIVE

To describe variability in spinal manipulation technique details and adverse event (AE) documentation of spinal manipulation during pregnancy.

METHODS

Five databases were searched for peer-reviewed investigations of spinal manipulation during pregnancy. Criteria for inclusion was as follows: high velocity, low amplitude thrust manipulation performed, subjects pregnant during manipulation, and English language. Studies were excluded when participants were not currently pregnant, and when the manipulation performed was not high-velocity, low-amplitude thrust. Data extraction included study design, number of participants, gestational age, spinal region, number of manipulations, manipulation technique details, profession of manipulator, AE reporting (Yes vs. No), type, and number of AE.

RESULTS

Out of 18 studies included in the review, only three provide details of the spinal manipulation technique. The reported variables include patient position, practitioner position, and direction of thrust. Fourteen studies documented AE; however, only seven provide AE details.

DISCUSSION

Reporting of spinal manipulation techniques and AE during pregnancy were inconsistent. Replication of methods in future investigations is limited without more detailed documentation of manipulation techniques performed. Furthermore, determining the relative risk and safety of spinal manipulation during pregnancy is not possible without more detailed reporting of AE. Due to these inconsistencies, a checklist is proposed for standardized reporting of spinal manipulation techniques and AE. With more consistent reporting of these parameters, results of future investigations may allow for more definitive and generalizable safety recommendations on spinal manipulation during pregnancy.

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

Introduction

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

Purpose

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

Implications

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

Inter-individual variability in mechanical pain sensation in patients with cervicogenic headache: an explorative study

Currently, evidence for effective physiotherapy interventions in patients with cervicogenic headache (CeH) is inconsistent. Although inter-individual variability in pain response is predictive for successful physiotherapy interventions, it was never explored in patients with CeH. Therefore the objective of the current study was to explore inter-individual variability in mechanical pain sensation, and its association with biopsychosocial-lifestyle (BPSL) characteristics in patients with CeH. A cross-sectional explorative analysis of inter-individual variability in mechanical pain sensation in 18 participants with CeH (29-51 years) was conducted. Inter-individual variability in mechanical pain sensation (standard deviations (SDs), F-statistics, Measurement System Analysis) was deducted from bilateral pressure pain thresholds of the suboccipitals, erector spine, tibialis anterior. BPSL-characteristics depression, anxiety, stress (Depression Anxiety Stress Scale-21), quality of life (Headache Impact Test-6), sleep-quality (Pittsburgh Sleep Quality Index), and sedentary time (hours/week) were questioned. Inter-individual variability in mechanical pain sensation explained 69.2% (suboccipital left), 86.8% (suboccipital right), 94.6% (erector spine left), 93.2% (erector spine right), 91.7% (tibialis anterior left), and 82% (tibialis anterior right) of the total variability in patients with CeH. The significant p-values and large F-statistic values indicate inter-individual differences in SDs. Significant associations between (1) lower quality of life and lower SDs of the suboccipital left PPT (p .005), and (2) longer sedentary time and higher SDs of the suboccipital left PPT (p .001) were observed. Results from our explorative study could suggest inter-individual variability in mechanical pain sensation at the left suboccipitals which associates with quality of life and sedentary time. These novel findings should be considered when phenotyping patients and 'individually' match interventions.

Cervical and scapula-focused resistance exercise program versus trapezius massage in patients with chronic neck pain: A randomized controlled trial

OBJECTIVE

The purpose of this study was to investigate the effects of resistance exercise in comparison with those of common exercise on chronic neck pain (CNP) to provide useful clinical guidelines for reducing pain or increasing cervical range of motion (ROM), upper trapezius tone, disability level, and quality of life (QOL).

METHODS

The subjects were randomized into a cervical and scapula-focused resistance exercise group (CSREG, n = 21) or trapezius massage group (TMG, n = 20). All groups received a 4-week, five times per week CSRE or TM program for CNP. The visual analogue scale (VAS) score, cervical ROM, myotonometer measures (upper trapezius tone, stiffness, and elasticity), neck disability index (NDI), and short form-36 (SF-36) were identified as the primary outcomes.

RESULTS

Within-group changes in VAS, cervical ROM, myotonometer measures, NDI, and SF-36 were significant in the CSREG and TMG (P < .05). The between-group changes in VAS, cervical rotation, myotonometer (upper trapezius tone and stiffness), NDI, and SF-36 after intervention showed significant differences between the CSREG and TMG (P < .05).

CONCLUSION

These results suggest that the CSRE program is effective in improving pain, cervical ROM, upper trapezius tone, disability level, and QOL in patients with CNP. More comprehensive studies with longer follow-up durations are needed to better understand the potential effects of the CSRE program in patients with CNP.

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.

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

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

Consensus among musculoskeletal experts for the management of patients with headache by physiotherapists? A delphi study

BACKGROUND

Though a large amount of research on the management of headache has been conducted, the clinical effectiveness of these treatments remains unclear.

OBJECTIVES

To reach consensus among international musculoskeletal experts on what the most appropriate management is in patients that suffer from headache.

DESIGN

Expert group and Delphi-study.

METHODS

A total of 11 experts participated in the expert panel groups, where the role of physiotherapy in the management of headache was discussed. Afterwards, 14 of the initial 25 participants in the field of headache completed the whole Delphi study, which was conducted over 4 rounds. The first round aimed to identify clinical indicators and treatments that are useful in patients with headache. These questions were then categorized and ranked during the second, third, and fourth rounds. Consensual agreement was set at ≥ 80%.

RESULTS

After the final round, 9 interventions were rated as useful by the participants. In the final extra round, 14 clinical indicators were retrieved as important to decide whether or not to start one of the consensual treatments. The top 3 management strategies were (1) upper cervical spine mobilisations in cervivogenic headache, (2) active mobilisation exercises of the cervical spine in cervivogenic headache, and (3) lifestyle advice in tension-type headache and migraine.

CONCLUSION

International experts agreed that most scientifically established effective treatments are useful in cervicogenic headache. Consensual agreement on treatments for migraine and tension-type headache were only reached for specific treatments. Their recommendations provide a framework for further research and the clinical management of headache.

Does restoration of sagittal cervical alignment improve cervicogenic headache pain and disability: A 2-year pilot randomized controlled trial

BACKGROUND

To investigate the feasibility and effect of a multimodal program for improving chronic cervicogenic headache (CGH) via the addition of sagittal cervical spine alignment correction.

DESIGN

Pilot, parallel-group, randomized controlled trial.

PARTICIPANTS

60 patients with CGH, straightening of the cervical lordosis, and forward head posture (FHP) were randomly assigned using permuted-block randomization either to a control (n = 30) or an experimental group (n = 30).

INTERVENTIONS

Subjects in both groups received a multimodal program where the denneroll cervical spine extension traction orthotic was added to the experimental group only. Feasibility was assessed through recruitment rate, compliance rate, adherence rate, safety, and global satisfaction in addition to clinical outcome measures: FHP distance, cervical lordosis, headache frequency, headache disability inventory (HDI), headache impact test-6 (HIT-6), and daily defined dose (DDD). Evaluations were performed at: baseline, 10 weeks, 1 year follow up, and 2-year follow up. The assessor was blind to group allocation for all measured outcomes.

RESULTS

The recruitment rate was 60%, 78 % out of them completed the entire study. The recruited participants complied with 98% of the required visits. No adverse events were recorded and greater overall satisfaction with the interventions was reported. Greater improvements were found for the experimental group's cervical lordosis (f = 259.9, P< < .001) and FHP (f = 142.5, P< < .001). At 10 weeks, both groups showed equal improvements in CGH outcomes: headache frequency (P = 0.07), HDI (P = 0.07), HIT-6 (P = .2), and DDD (P = .3). In contrast, at the 1-year and 2-year follow up, between group differences were found for all CGH outcomes, P < .00, indicating greater improvement in the experimental group.

CONCLUSION

The results indicated feasibility for recruitment rate, compliance rate, exercise session adherence, safety, and global satisfaction. At 1-year and 2-year follow-up, the addition of the denneroll orthotic device revealed positive influence on CGH management outcomes.

TRIAL REGISTRATION

The trial was retrospectively registered with the Pan African Clinical Trial Registry (PACTR201605001650300).

A sonographic comparison of the effect of dry needling and ischemic compression on the active trigger point of the sternocleidomastoid muscle associated with cervicogenic headache: A randomized trial

BACKGROUND

Cervicogenic headache (CeH) is among the common types of headache which has an undesirable influence on the quality of life. The myofascial trigger point (MTrP) within the sternocleidomastoid (SCM) muscle is one of the most important causes of CeH.

OBJECTIVE

The purpose of this study was to compare the effect of dry needling (DN) and ischemic compression (IC) on the headache symptoms as well as MTrP-related features in subjects with CeH originating from MTrPs of the SCM muscle using a sonographic method.

METHODS

A total of 29 female subjects aged 35.34 ± 12.19 on average with a clinical diagnosis of CeH originating from MTrP in the SCM muscle were randomly divided into the DN, IC, and control groups. Both DN and IC groups received 4 treatment sessions. Headache intensity, duration, frequency, MTrP elastic modulus, MTrP area, and pressure pain threshold (PPT) were assessed 2 weeks before and after treatments.

RESULTS

In both DN and IC groups, a significant improvement was found in the headache intensity, duration, frequency, PPT, and MTrP area (P< 0.05). No significant differences were observed between DN and IC (P> 0.05). Pearson correlation revealed a significant correlation between headache intensity and the MTrP elastic modulus (P< 0.05).

CONCLUSIONS

Both interventions could reduce headache symptoms, PPT, and MTrP area. Neither intervention was found to be superior to the other in short-term follow-up. IC may be preferred since it has fewer unwanted side effects compared to DN. Based on the data, it may be concluded that some MTrP biomechanical features such as stiffness may influence the produced headache symptoms.

Spinal manipulation for the management of cervicogenic headache: A systematic review and meta-analysis

BACKGROUND

Spinal manipulative therapy (SMT) is frequently used to manage cervicogenic headache (CGHA). No meta-analysis has investigated the effectiveness of SMT exclusively for CGHA.

OBJECTIVE

To evaluate the effectiveness of SMT for CGHA.

DATABASES AND DATA TREATMENT

Five databases identified randomized controlled trials comparing SMT with other manual therapies. The PEDro scale assessed the risk-of-bias. Pain and disability data were extracted and converted to a common scale. A random effects model was used for several follow-up periods. GRADE described the quality of evidence.

RESULTS

Seven trials were eligible. At short-term follow-up, there was a significant, small effect favouring SMT for pain intensity (mean difference [MD] -10.88 [95% CI, -17.94, -3.82]) and small effects for pain frequency (standardized mean difference [SMD] -0.35 [95% CI, -0.66, -0.04]). There was no effect for pain duration (SMD - 0.08 [95% CI, -0.47, 0.32]). There was a significant, small effect favouring SMT for disability (MD - 13.31 [95% CI, -18.07, -8.56]). At intermediate follow-up, there was no significant effects for pain intensity (MD - 9.77 [-24.21 to 4.68]) and a significant, small effect favouring SMT for pain frequency (SMD - 0.32 [-0.63 to - 0.00]). At long-term follow-up, there was no significant effects for pain intensity (MD - 0.76 [-5.89 to 4.37]) and for pain frequency (SMD - 0.37 [-0.84 to 0.10]).

CONCLUSION

For CGHA, SMT provides small, superior short-term benefits for pain intensity, frequency and disability, but not pain duration, however, high-quality evidence in this field is lacking. The long-term impact is not significant.

SIGNIFICANCE

CGHA are a common headache disorder. SMT can be considered an effective treatment modality, with this review suggesting it providing superior, small, short-term effects for pain intensity, frequency and disability when compared with other manual therapies. These findings may help clinicians in practice better understand the treatment effects of SMT alone for CGHA.

Clinical Reasoning Behind Non-Pharmacological Interventions for the Management of Headaches: A Narrative Literature Review

Headache is the clinical syndrome most commonly observed by neurologists in daily practice. Pharmacological and non-pharmacological treatments are commonly used for the management of headaches; however, the clinical reasoning behind these interventions is not properly applied. We conducted a narrative literature review using as data sources for academic PubMed, MEDLINE, EMBASE, AMED, CINAHL, EBSCO, PEDro, Cochrane Database of Systematic Reviews, Cochrane Collaboration Trials Register, and SCOPUS. This narrative literature review mainly considered systematic reviews, meta-analyses, randomised clinical trials, and expert opinions published after the year 2000 discussing clinical reasoning for application of non-pharmacological interventions in individuals with tension-type, migraine, and cervicogenic headaches. After the data extraction, we organized the literature thematically as follows: (1) mapping of theoretical aspects of non-pharmacological interventions; (2) summarizing most updated literature about effectiveness of non-pharmacological interventions grouped by targeted tissue and headache; (3) identifying research gaps in the existing literature and proposing hypotheses for better understanding of current clinical reasoning. We found that there are many non-pharmacological treatment strategies used for headaches, including beyond the tissue-based impairment treatments (bottom-up) and strategies targeting the central nervous system (top down). Bottom-up strategies include joint-biased, soft-tissue biased, or needling interventions, whereas top-down strategies include exercise and cognitive interventions. Evidence shows that the effectiveness of these interventions depends on the application of proper clinical reasoning, since not all strategies are effective for all headaches. For instance, evidence of non-pharmacological interventions is more controversial for migraines than for tension-type or cervicogenic headaches, since migraine pathogenesis involves activation of sub-cortical structures and the trigemino- vascular system, whereas pathogenesis of tension-type or cervicogenic headaches is most associated to musculoskeletal impairments of the cervical spine. We conclude that current literature suggests that not all non-pharmacological interventions are effective for all headaches, and that multimodal, not isolated, approaches seem to be more effective for patients with headaches. Most published studies have reported small clinical effects in the short term. This narrative literature review provides some hypotheses for discrepancies in the available literature and future research. Clinical reasoning should be applied to better understand the effects of non-pharmacological interventions.

Neck pain in South Africa: An overview of the prevalence, assessment and management for the contemporary clinician

BACKGROUND

Neck pain is a prevalent condition and is associated with high levels of disability and pain. The long-term prognosis can be poor, and therefore effective management in the acute stage is important.

OBJECTIVES

To provide an overview of the prevalence of neck pain and physiotherapy management and to provide evidence-informed recommendations for clinical practice within a South African context.

METHOD

The literature was reviewed considering prevalence, risk factors and examination. Management recommendations were derived from the highest levels of evidence of clinical practice guidelines, systematic reviews and randomised clinical trials.

RESULTS

Neck pain is classified into four grades, and three trajectories of recovery have been identified. Although the incidence of neck pain globally is high, in the South African context the majority of the population have limited access to physiotherapy management. Sound clinical reasoning is important in the assessment and decision-making process for management. Exercise, and mobilisation or manipulation are effective treatment options in the management of most types of neck pain. Other physical modalities such as needling, transcutaneous electrical nerve stimulation, laser and intermittent traction may be used as an adjunct to management.

CONCLUSION

The burden of neck pain globally is high; however, there is a lack of information on current practice, prevalence and burden of neck pain in the South African context. Sound evidence-informed clinical reasoning to inform a working diagnosis and to enable patient-centred management is important.

CLINICAL IMPLICATIONS

A thorough assessment is essential to gather information to formulate hypotheses regarding diagnosis and prognosis for neck pain. Exercise, and mobilisation or manipulation are effective management options.

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.

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.

The management of common recurrent headaches by chiropractors: a descriptive analysis of a nationally representative survey

BACKGROUND

Headache management is common within chiropractic clinical settings; however, little is yet known about how this provider group manage headache sufferers. The aim of this study is to report on the prevalence of headache patients found within routine chiropractic practice and to assess how chiropractors approach key aspects of headache management applicable to primary care settings.

METHODS

A 31-item cross-sectional survey was distributed to a national sample of chiropractors (n = 1050) to report on practitioner approach to headache diagnosis, interdisciplinary collaboration, treatment and outcome assessment of headache patients who present with recurrent headache disorders.

RESULTS

The survey attracted a response rate of 36% (n = 381). One in five new patients present to chiropractors with a chief complaint of headache. The majority of chiropractors provide headache diagnosis for common primary (84.6%) and secondary (90.4%) headaches using formal headache classification criteria. Interdisciplinary referral for headache management was most often with CAM providers followed by GPs. Advice on headache triggers, stress management, spinal manipulation, soft tissue therapies and prescriptive neck exercises were the most common therapeutic approaches to headache management.

CONCLUSION

Headache patients make up a substantial proportion of chiropractic caseload. The majority of chiropractors managing headache engage in headache diagnosis and interdisciplinary patient management. More research information is needed to understand the headache types and level of headache chronicity and disability common to chiropractic patient populations to further assess the healthcare needs of this patient population.

Comparison of acute effects of superficial and deep dry needling into trigger points of suboccipital and upper trapezius muscles in patients with cervicogenic headache

OBJECTIVE

The purpose of this study was to compare the acute effects of superficial and deep dry needling into trigger points of suboccipital and upper trapezius muscles in patients with cervicogenic headache.

METHODS

Thirty participants (8 men, 22 women) aged 19-60 years (mean age ± SD, 39 ± 10 y) with a clinical diagnosis of cervicogenic headache were randomly divided into superficial and deep groups. Headache index, trigger points tenderness, cervical range of motion (CROM), functional rating index was assessed at baseline, immediate and 1 week after the treatment.

RESULTS

Two approaches of dry needling showed reduction in headache index and trigger points tenderness. Deep dry needling showed greater improvement of cervical range of motion (p < 0.001) and functional rating index (p < 0.01).

CONCLUSION

The application of dry needling into trigger points of suboccipital and upper trapezius muscles induces significant improvement of headache index, trigger points tenderness, functional rating index and range of motion in patients with cervicogenic headache. Deep dry needling had greater effects on CROM and function.

Prevalence, characteristics and management of headache experienced by people with schizophrenia and schizoaffective disorder: a cross sectional cohort study

OBJECTIVES

Headache is the most common type of pain reported by people with schizophrenia. This study aimed to establish prevalence, characteristics and management of these headaches.

METHODS

One hundred participants with schizophrenia/schizoaffective disorder completed a reliable and valid headache questionnaire. Two clinicians independently classified each headache as migraine, tension-type, cervicogenic or other.

RESULTS

The 12-month prevalence of headache (57%) was higher than the general population (46%) with no evidence of a relationship between psychiatric clinical characteristics and presence of headache. Prevalence of cervicogenic (5%) and migraine (18%) was comparable to the general population. Tension-type (16%) had a lower prevalence and 19% of participants experienced other headache. No one with migraine was prescribed migraine specific medication; no one with cervicogenic and tension-type received best-practice treatment.

CONCLUSIONS

Headache is a common complaint in people with schizophrenia/schizoaffective disorder with most fitting recognised diagnostic criteria for which effective interventions are available. No one in this sample was receiving best-practice care for their headache.

A CONCEPTUAL MODEL FOR PHYSICAL THERAPISTS TREATING ATHLETES WITH PROTRACTED RECOVERY FOLLOWING A CONCUSSION

Sports-related concussions are receiving growing attention in healthcare. Most concussions resolve spontaneously with little or no treatment, but twenty percent of concussions take longer than three weeks to resolve. In some cases, symptoms can last for five years following a traumatic brain injury. Physical Therapists have unique skills that can assist patients experiencing protracted recovery. The purpose of this clinical commentary is to describe a new conceptual model that provides a framework for Physical Therapy management of patients with protracted recovery following a sports-related concussion. The end product is a visual diagram that represents the full scope of clinical practice that Physical Therapy can provide to an athlete following a concussion.

A critical review of manual therapy use for headache disorders: prevalence, profiles, motivations, communication and self-reported effectiveness

Background

Despite the expansion of conventional medical treatments for headache, many sufferers of common recurrent headache disorders seek help outside of medical settings. The aim of this paper is to evaluate research studies on the prevalence of patient use of manual therapies for the treatment of headache and the key factors associated with this patient population.

Methods

This critical review of the peer-reviewed literature identified 35 papers reporting findings from new empirical research regarding the prevalence, profiles, motivations, communication and self-reported effectiveness of manual therapy use amongst those with headache disorders.

Results

While available data was limited and studies had considerable methodological limitations, the use of manual therapy appears to be the most common non-medical treatment utilized for the management of common recurrent headaches. The most common reason for choosing this type of treatment was seeking pain relief. While a high percentage of these patients likely continue with concurrent medical care, around half may not be disclosing the use of this treatment to their medical doctor.

Conclusions

There is a need for more rigorous public health and health services research in order to assess the role, safety, utilization and financial costs associated with manual therapy treatment for headache. Primary healthcare providers should be mindful of the use of this highly popular approach to headache management in order to help facilitate safe, effective and coordinated care.

Cervico-cephalalgiaphobia: a subtype of phobia in patients with cervicogenic headache and neck pain? A pilot study

OBJECTIVES

The term 'cephalalgiaphobia' was introduced in the mid-1980s and defined as fear of migraine (attacks). We hypothesized that a specific subtype of cephalalgiaphobia affects patients with cervicogenic headache (CEH). This study aimed to: (1) define the term 'cervico-cephalalgiaphobia'; (2) develop a set of indicators for phobia relevant to patients with CEH; and (3) apply this set to a practice test in order to estimate the frequency of cervico-cephalalgiaphobia in the Dutch primary care practice of manual physical therapy.

METHODS

A systematic approach was used to develop a definition and potential indicators for cervico-cephalalgiaphobia. An expert group appraised the definition and the set of indicators (score per indicator: never; sometimes; often/always). An invitation to participate in the practice test was sent to Dutch manual physical therapy practices (n = 56) representing 134 manual physical therapists (MPTs). The cut-off point for percentages of scores for coverage of the indicators was set at ≥ 60%.

RESULTS

The expert group agreed with the proposed definition of cervico-cephalalgiaphobia. A set of eight indicators for cervico-cephalalgiaphobia was selected from 10 initial indicators. Thirty-six MPTs provided data from 46 patients diagnosed with CEH. The coverage of 'often/always' was substantial for the indicators, 'Short-term positive results in previous manual physical therapeutic treatment', 'Shorter interval between treatment sessions', 'Fear of "locked facet joints" of the neck', 'More frequent manipulation', and 'Fear of increase in headaches'. Coverage was also substantial for 'never' regarding 'Long-term positive results in previous manual physical therapeutic treatment'. 'Confirmation of "locked facet joints" of the cervical spine by MPT as a cause for increase of CEH' scored 'often/always' in all patients. Coverage for 'Increased use of medication with insufficient effect' was substantial, scoring as 'sometimes' in 39 (84.8%) patients.

DISCUSSION

Cervico-cephalalgiaphobia was defined and a set of eight indicators formulated based on the literature and clinical expertise. The practice test provides valuable information on the frequency of indicators for cervico-cephalalgiaphobia in the Dutch manual physical therapy practice, suggesting that cervico-cephalalgiaphobia is common in patients with CEH.

Physical therapy for headaches

Background Headache is the medical problem most commonly observed by neurologists. Non-pharmacological treatments are commonly demanded by individuals with headaches, but their evidence of effectiveness is conflicting. Aim The current review provides an updated discussion on what is supported by current scientific evidence about physical therapies for tension-type headache (TTH), migraine, and cervicogenic headache (CeH), and which gaps there still may be in our understanding of the interventions. Methods PubMed, MEDLINE, EMBASE, AMED, CINAHL, EBSCO, Cochrane Database of Systematic Reviews, Cochrane Collaboration Trials Register, PEDro, and SCOPUS were searched from their inception through March 2015. Results/Discussion Several physical therapies including spinal joint manipulation/mobilization, soft tissue interventions, therapeutic exercises and needling therapies are proposed to be effective for the management of headaches. Current evidence has shown that the effectiveness of these interventions will depend on proper clinical reasoning since not all interventions are equally effective for all headache pain conditions. For instance, evidence of physical therapy in migraine is more controversial than in TTH, since migraine pathogenesis involves activation of sub-cortical structures and the trigemino-vascular system, whereas pathogenesis of TTH is more associated with musculoskeletal disorders, e.g. muscle pain. It seems that multimodal approaches including different interventions are more effective for patients with TTH, migraine and CeH.

Spinal rehabilitative exercise or manual treatment for the prevention of cervicogenic headache in adults

This is the protocol for a review and there is no abstract. The objectives are as follows: To quantify and compare the short- and long-term effects of manual treatment and spinal rehabilitative exercise for cervicogenic headache, classified according to the International Headache Society's (IHS) diagnostic criteria, with an active or placebo/sham comparison or wait-list control.

Therapeutic Exercise Training to Reduce Chronic Headache in Working Women: Design of a Randomized Controlled Trial

BACKGROUND

Cervicogenic headache and migraine are common causes of visits to physicians and physical therapists. Few randomized trials utilizing active physical therapy and progressive therapeutic exercise have been previously published. The existing evidence on active treatment methods supports a moderate effect on cervicogenic headache.

OBJECTIVE

The aim of this study is to investigate whether a progressive, group-based therapeutic exercise program decreases the intensity and frequency of chronic headache among women compared with a control group receiving a sham dose of transcutaneous electrical nerve stimulation (TENS) and stretching exercises.

DESIGN

A randomized controlled trial with 6-month intervention and follow-up was developed. The participants were randomly assigned to either a treatment group or a control group.

SETTING

The study is being conducted at 2 study centers.

PATIENTS

The participants are women aged 18 to 60 years with chronic cervicogenic headache or migraine.

INTERVENTION

The treatment group's exercise program consisted of 6 progressive therapeutic exercise modules, including proprioceptive low-load progressive craniocervical and cervical exercises and high-load exercises for the neck muscles. The participants in the control group received 6 individually performed sham TENS treatment sessions.

MEASUREMENTS

The primary outcome is the intensity of headache. The secondary outcomes are changes in frequency and duration of headache, neck muscle strength, neck and shoulder flexibility, impact of headache on daily life, neck disability, fear-avoidance beliefs, work ability, and quality of life. Between-group differences will be analyzed separately at 6, 12, and 24 months with generalized linear mixed models. In the case of count data (eg, frequency of headache), Poisson or negative binomial regression will be used.

LIMITATIONS

The therapists are not blinded.

CONCLUSIONS

The effects of specific therapeutic exercises on frequency, intensity, and duration of chronic headache and migraine will be reported.

Exercises for mechanical neck disorders: A Cochrane review update

BACKGROUND

Neck pain (NP) is disabling and costly.

OBJECTIVES

To assess the effectiveness of exercise on pain, disability, function, patient satisfaction, quality of life (QoL) and global perceived effect (GPE) in adults with NP.

METHODS

We searched computerised databases up to May 2014 for randomized controlled trials (RCTs) comparing exercise to a control in adults with NP with/without cervicogenic headache (CGH) or radiculopathy. Two reviewers independently conducted selection, data abstraction and assessed risk of bias. Meta-analyses were performed to establish pooled standardised mean differences (SMDp). The Grade of Recommendation, Assessment, Development and Evaluation (GRADE) was used to summarise the body of evidence.

MAIN RESULTS

The following exercises (27 trials) were supported by 'Moderate GRADE' evidence: For chronic NP, 1) cervico-scapulothoracic and upper extremity (UE) strengthening for moderate to large pain reduction immediately post treatment (IP) and at short-term (ST) follow-up; 2) scapulothoracic and UE endurance training for a small pain reduction (IP/ST); 3) cervical, shoulder and scapulothoracic strengthening and stretching exercise for a small to large pain reduction in the long-term (LT) (SMDp -0.45 [95%CI: -0.72 to -0.18]) and function improvement; 4) cervico-scapulothoracic strengthening/stabilisation exercises for pain and function at intermediate-term (IT) (SMDp -14.90 [95%CI: -22.40 to -7.39]). 5) mindfulness exercises (Qigong) for minor improved function but not GPE (ST). For chronic CGH, cervico-scapulothoracic strengthening and endurance exercises including pressure biofeedback for small/moderate improvement of pain, function and GPE (IP/LT).

AUTHORS' CONCLUSIONS

Specific strengthening exercises of the neck, scapulothoracic and shoulder for chronic NP and chronic CGH are beneficial. Future research should explore optimal dosage.

Mobilization and Manipulation of the Cervical Spine in Patients with Cervicogenic Headache: Any Scientific Evidence?

Cervical mobilization and manipulation are frequently used to treat patients diagnosed with cervicogenic headache (CEH); however, there is conflicting evidence on the efficacy of these manual therapy techniques. The purpose of this review is to investigate the effects of cervical mobilization and manipulation on pain intensity and headache frequency, compared to traditional physical therapy interventions in patients diagnosed with CEH. A total of 66 relevant studies were originally identified through a review of the literature, and the 25 most suitable articles were fully evaluated via a careful review of the text. Ultimately, 10 studies met the inclusion criteria: (1) randomized controlled trial (RCT) or open RCT; the study contained at least two separate groups of subjects that were randomly assigned either to a cervical spine mobilization or manipulation or a group that served as a comparison; (2) subjects must have had a diagnosis of CEH; (3) the treatment group received either spinal mobilization or spinal manipulation, while the control group received another physical therapy intervention or placebo control; and (4) the study included headache pain and frequency as outcome measurements. Seven of the 10 studies had statistically significant findings that subjects who received mobilization or manipulation interventions experienced improved outcomes or reported fewer symptoms than control subjects. These results suggest that mobilization or manipulation of the cervical spine may be beneficial for individuals who suffer from CEH, although heterogeneity of the studies makes it difficult to generalize the findings.

Cervicogenic somatosensory tinnitus: An indication for manual therapy plus education? Part 2: A pilot study

OBJECTIVES

The aim of this study was to evaluate the efficacy of Manual Therapy Utrecht (MTU) plus education in patients with cervicogenic somatosensory tinnitus (CeT).

STUDY DESIGN

Pretest-posttest design.

METHOD

Five hundred and six patients were referred or referred themselves. A subgroup of patients was identified with CeT, and within this a subgroup with tinnitus sensitization (TS). Two CeT groups were created based on the presence or absence of TS. Both groups underwent manual therapy combined with tinnitus education. Tinnitus intensity (VAS-tin 0-100 mm) was the primary outcome measure. Number of treatments and adverse effects were the secondary outcome measures.

RESULTS

A total of 122 patients with CeT (24.1%) were included (average age 53.3 years [±9.8], female 38.5% and duration of tinnitus 7.3 years [±8.9]). Patients were divided into two groups: 55 patients (45.1%) with TS (CeT + TS group) and 67 patients (54.9%) without TS (CeT - TS group). Pretest to posttest differences on the VAS-tin were statistically significant within both groups (CeT - TS group: difference VAS-tin 5.9 [p = 0.01]; CeT + TS group: difference VAS-tin 18.2 [p = 0.00]), and between the groups in favor of the CeT + TS group (difference VAS-tin 12.3 [p = 0.01]). Pretest to posttest differences were clinically significant for the CeT + TS group (difference VAS-tin 18.2 [MCIC = ≥10 mm VAS-tin]) and between the groups (difference VAS-tin 12.3 in favor of the CeT + TS group). The average number of treatment sessions was 9.6 (±2.6) for the CeT - TS group and 10.3 (±2.5) for the CeT + TS group, a non-significant difference. There were no adverse effects in either group.

CONCLUSIONS

Despite its limitations, this study provides valuable information on both the characteristics of patients with CeT and TS in a Dutch primary care manual therapy practice and on the potential effectiveness of MTU combined with tinnitus education for the subgroup of CeT + TS patients.

Manual Therapy and Exercise for a Patient With Neck-Tongue Syndrome: A Case Report

STUDY DESIGN

Case report.

BACKGROUND

Neck-tongue syndrome (NTS) is defined as neck and/or head pain accompanied by ipsilateral dysesthesia of the tongue with sudden rotation of the head. Proposed causes include compression or irritation of the C2 nerve root as it courses behind the atlantoaxial joint or hypertrophy of the inferior oblique muscle. The primary purpose of this case report was to describe the conservative physical therapy treatment of a patient with uncomplicated NTS.

CASE DESCRIPTION

The patient was a 13-year-old girl who reported insidious onset of sharp pain in the neck, numbness/tingling of the ipsilateral tongue/face, and tinnitus with cervical rotation. Symptoms occurred several times a week for approximately 10 seconds. Examination revealed impaired function, increased forward head posture, decreased cervical range of motion, and positive neurodynamic assessment. The patient's treatment included manual therapy and exercise for postural stabilization.

OUTCOMES

Following 8 visits, pain of the neck and tongue numbness had resolved. Score on the Patient-Specific Functional Scale (PSFS), cervical range of motion, and posture had also improved. At the 22-month follow-up, infrequent, momentary symptoms in the neck and dysesthesia of the tongue were reported. The PSFS remained the same. Objective measures were normal.

DISCUSSION

This case report describes the physical therapy management of an individual with NTS. The management strategy followed a protocol similar to that used for cervicogenic headaches, due to the involvement of the upper cervical spine with both NTS and cervicogenic headache and the lack of evidence for the treatment of NTS. Level of Evidence Therapy, level 4.

Manipulation and mobilisation for neck pain contrasted against an inactive control or another active treatment

BACKGROUND

Manipulation and mobilisation are commonly used to treat neck pain. This is an update of a Cochrane review first published in 2003, and previously updated in 2010.

OBJECTIVES

To assess the effects of manipulation or mobilisation alone compared wiith those of an inactive control or another active treatment on pain, function, disability, patient satisfaction, quality of life and global perceived effect in adults experiencing neck pain with or without radicular symptoms and cervicogenic headache (CGH) at immediate- to long-term follow-up. When appropriate, to assess the influence of treatment characteristics (i.e. technique, dosage), methodological quality, symptom duration and subtypes of neck disorder on treatment outcomes.

SEARCH METHODS

Review authors searched the following computerised databases to November 2014 to identify additional studies: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We also searched ClinicalTrials.gov, checked references, searched citations and contacted study authors to find relevant studies. We updated this search in June 2015, but these results have not yet been incorporated.

SELECTION CRITERIA

Randomised controlled trials (RCTs) undertaken to assess whether manipulation or mobilisation improves clinical outcomes for adults with acute/subacute/chronic neck pain.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, abstracted data, assessed risk of bias and applied Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methods (very low, low, moderate, high quality). We calculated pooled risk ratios (RRs) and standardised mean differences (SMDs).

MAIN RESULTS

We included 51 trials (2920 participants, 18 trials of manipulation/mobilisation versus control; 34 trials of manipulation/mobilisation versus another treatment, 1 trial had two comparisons). Cervical manipulation versus inactive control: For subacute and chronic neck pain, a single manipulation (three trials, no meta-analysis, 154 participants, ranged from very low to low quality) relieved pain at immediate- but not short-term follow-up. Cervical manipulation versus another active treatment: For acute and chronic neck pain, multiple sessions of cervical manipulation (two trials, 446 participants, ranged from moderate to high quality) produced similar changes in pain, function, quality of life (QoL), global perceived effect (GPE) and patient satisfaction when compared with multiple sessions of cervical mobilisation at immediate-, short- and intermediate-term follow-up. For acute and subacute neck pain, multiple sessions of cervical manipulation were more effective than certain medications in improving pain and function at immediate- (one trial, 182 participants, moderate quality) and long-term follow-up (one trial, 181 participants, moderate quality). These findings are consistent for function at intermediate-term follow-up (one trial, 182 participants, moderate quality). For chronic CGH, multiple sessions of cervical manipulation (two trials, 125 participants, low quality) may be more effective than massage in improving pain and function at short/intermediate-term follow-up. Multiple sessions of cervical manipulation (one trial, 65 participants, very low quality) may be favoured over transcutaneous electrical nerve stimulation (TENS) for pain reduction at short-term follow-up. For acute neck pain, multiple sessions of cervical manipulation (one trial, 20 participants, very low quality) may be more effective than thoracic manipulation in improving pain and function at short/intermediate-term follow-up. Thoracic manipulation versus inactive control: Three trials (150 participants) using a single session were assessed at immediate-, short- and intermediate-term follow-up. At short-term follow-up, manipulation improved pain in participants with acute and subacute neck pain (five trials, 346 participants, moderate quality, pooled SMD -1.26, 95% confidence interval (CI) -1.86 to -0.66) and improved function (four trials, 258 participants, moderate quality, pooled SMD -1.40, 95% CI -2.24 to -0.55) in participants with acute and chronic neck pain. A funnel plot of these data suggests publication bias. These findings were consistent at intermediate follow-up for pain/function/quality of life (one trial, 111 participants, low quality). Thoracic manipulation versus another active treatment: No studies provided sufficient data for statistical analyses. A single session of thoracic manipulation (one trial, 100 participants, moderate quality) was comparable with thoracic mobilisation for pain relief at immediate-term follow-up for chronic neck pain. Mobilisation versus inactive control: Mobilisation as a stand-alone intervention (two trials, 57 participants, ranged from very low to low quality) may not reduce pain more than an inactive control. Mobilisation versus another active treatment: For acute and subacute neck pain, anterior-posterior mobilisation (one trial, 95 participants, very low quality) may favour pain reduction over rotatory or transverse mobilisations at immediate-term follow-up. For chronic CGH with temporomandibular joint (TMJ) dysfunction, multiple sessions of TMJ manual therapy (one trial, 38 participants, very low quality) may be more effective than cervical mobilisation in improving pain/function at immediate- and intermediate-term follow-up. For subacute and chronic neck pain, cervical mobilisation alone (four trials, 165 participants, ranged from low to very low quality) may not be different from ultrasound, TENS, acupuncture and massage in improving pain, function, QoL and participant satisfaction at immediate- and intermediate-term follow-up. Additionally, combining laser with manipulation may be superior to using manipulation or laser alone (one trial, 56 participants, very low quality).

AUTHORS' CONCLUSIONS

Although support can be found for use of thoracic manipulation versus control for neck pain, function and QoL, results for cervical manipulation and mobilisation versus control are few and diverse. Publication bias cannot be ruled out. Research designed to protect against various biases is needed. Findings suggest that manipulation and mobilisation present similar results for every outcome at immediate/short/intermediate-term follow-up. Multiple cervical manipulation sessions may provide better pain relief and functional improvement than certain medications at immediate/intermediate/long-term follow-up. Since the risk of rare but serious adverse events for manipulation exists, further high-quality research focusing on mobilisation and comparing mobilisation or manipulation versus other treatment options is needed to guide clinicians in their optimal treatment choices.

Cervicogenic causes of vertigo

PURPOSE OF REVIEW

Herein we discuss the recent literature concerning cervicogenic vertigo including vertigo associated with rotational vertebral artery syndrome, as well as whiplash and degenerative disturbances of the cervical spine. We conclude with a summary of progress regarding diagnostic methods for cervicogenic vertigo.

RECENT FINDINGS

Several additional single case studies of the exceedingly rare rotational vertebral artery syndrome have been added to the literature over the last year. Concerning whiplash and degenerative disturbances of the cervical spine, four reviews were published concerning using physical therapy as treatment, and two reviews reported successful surgical management. Publications regarding diagnostic methodology remain few and unconvincing, but the cervical torsion test appears the most promising.

SUMMARY

Little progress has been made over the last year concerning cervicogenic vertigo. As neck disturbances combined with dizziness are commonly encountered in the clinic, the lack of a diagnostic test that establishes that a neck disturbance causes vertigo remains the critical problem that must be solved.

Efficacy of interventions used by physiotherapists for patients with headache and migraine-systematic review and meta-analysis

AIM

We aimed to conduct a systematic review evaluating the effectiveness of interventions used by physiotherapists on the intensity, frequency and duration of migraine, tension-type (TTH) and cervicogenic headache (CGH).

METHODS

We performed a systematic search of electronic databases and a hand search for controlled trials. A risk of bias analysis was conducted using the Cochrane risk of bias tool (RoB). Meta-analyses present the combined mean effects; sensitivity analyses evaluate the influence of methodological quality.

RESULTS

Of 77 eligible trials, 26 were included in the RoB assessment. Twenty trials were included in meta-analyses. Nineteen out of 26 trials had a high RoB in >1 domain. Meta-analyses of all trials indicated a reduction of TTH ( ITALIC! p < 0.0001; mean reduction -1.11 on a 0-10 visual analog scale (VAS); 95% CI -1.64 to -0.57) and CGH ( ITALIC! p = 0.0002; mean reduction -2.52 on a 0-10 VAS; 95% CI -3.86 to -1.19) pain intensity, CGH frequency ( ITALIC! p < 0.00001; mean reduction -1.34 days per month; 95% CI -1.40 to -1.28), and migraine ( ITALIC! p = 0.0001; mean reduction -22.39 hours without relief; 95% CI -33.90 to -10.88) and CGH ( ITALIC! p < 0.00001; mean reduction -1.68 hours per day; 95% CI -2.09 to -1.26) duration. Excluding high RoB trials increased the effect sizes and reached additional statistical significance for migraine pain intensity ( ITALIC! p < 0.00001; mean reduction -1.94 on a 0-10 VAS; 95% CI -2.61 to -1.27) and frequency ( ITALIC! p < 0.00001; mean reduction -9.07 days per month; 95% CI -9.52 to -8.62).

DISCUSSION

Results suggest a statistically significant reduction in the intensity, frequency and duration of migraine, TTH and CGH. Pain reduction and reduction in CGH frequency do not reach clinically relevant effect sizes. Small sample sizes, inadequate use of headache classification, and other methodological shortcomings reduce the confidence in these results. Methodologically sound, randomized controlled trials with adequate sample sizes are required to provide information on whether and which physiotherapy approach is effective. According to Grading of Recommendations Assessment, Development and Evaluation (GRADE), the current level of evidence is low.

Chiropractic care and the risk of vertebrobasilar stroke: results of a case-control study in U.S. commercial and Medicare Advantage populations

Background

There is controversy surrounding the risk of manipulation, which is often used by chiropractors, with respect to its association with vertebrobasilar artery system (VBA) stroke. The objective of this study was to compare the associations between chiropractic care and VBA stroke with recent primary care physician (PCP) care and VBA stroke.

Methods

The study design was a case–control study of commercially insured and Medicare Advantage (MA) health plan members in the U.S. population between January 1, 2011 and December 31, 2013. Administrative data were used to identify exposures to chiropractic and PCP care. Separate analyses using conditional logistic regression were conducted for the commercially insured and the MA populations. The analysis of the commercial population was further stratified by age (<45 years; ≥45 years). Odds ratios were calculated to measure associations for different hazard periods. A secondary descriptive analysis was conducted to determine the relevance of using chiropractic visits as a proxy for exposure to manipulative treatment.

Results

There were a total of 1,829 VBA stroke cases (1,159 – commercial; 670 – MA). The findings showed no significant association between chiropractic visits and VBA stroke for either population or for samples stratified by age. In both commercial and MA populations, there was a significant association between PCP visits and VBA stroke incidence regardless of length of hazard period. The results were similar for age-stratified samples. The findings of the secondary analysis showed that chiropractic visits did not report the inclusion of manipulation in almost one third of stroke cases in the commercial population and in only 1 of 2 cases of the MA cohort.

Conclusions

We found no significant association between exposure to chiropractic care and the risk of VBA stroke. We conclude that manipulation is an unlikely cause of VBA stroke. The positive association between PCP visits and VBA stroke is most likely due to patient decisions to seek care for the symptoms (headache and neck pain) of arterial dissection. We further conclude that using chiropractic visits as a measure of exposure to manipulation may result in unreliable estimates of the strength of association with the occurrence of VBA stroke.

Exercises for mechanical neck disorders

BACKGROUND

Neck pain is common, disabling and costly. Exercise is one treatment approach.

OBJECTIVES

To assess the effectiveness of exercises to improve pain, disability, function, patient satisfaction, quality of life and global perceived effect in adults with neck pain.

SEARCH METHODS

We searched MEDLINE, MANTIS, ClinicalTrials.gov and three other computerized databases up to between January and May 2014 plus additional sources (reference checking, citation searching, contact with authors).

SELECTION CRITERIA

We included randomized controlled trials (RCTs) comparing single therapeutic exercise with a control for adults suffering from neck pain with or without cervicogenic headache or radiculopathy.

DATA COLLECTION AND ANALYSIS

Two review authors independently conducted trial selection, data extraction, 'Risk of bias' assessment and clinical relevance. The quality of the evidence was assessed using GRADE. Meta-analyses were performed for relative risk and standardized mean differences (SMD) with 95% confidence intervals (CIs) after judging clinical and statistical heterogeneity.

MAIN RESULTS

Twenty-seven trials (2485 analyzed /3005 randomized participants) met our inclusion criteria.For acute neck pain only, no evidence was found.For chronic neck pain, moderate quality evidence supports 1) cervico-scapulothoracic and upper extremity strength training to improve pain of a moderate to large amount immediately post treatment [pooled SMD (SMDp) -0.71 (95% CI: -1.33 to -0.10)] and at short-term follow-up; 2) scapulothoracic and upper extremity endurance training for slight beneficial effect on pain at immediate post treatment and short-term follow-up; 3) combined cervical, shoulder and scapulothoracic strengthening and stretching exercises varied from a small to large magnitude of beneficial effect on pain at immediate post treatment [SMDp -0.33 (95% CI: -0.55 to -0.10)] and up to long-term follow-up and a medium magnitude of effect improving function at both immediate post treatment and at short-term follow-up [SMDp -0.45 (95%CI: -0.72 to -0.18)]; 4) cervico-scapulothoracic strengthening/stabilization exercises to improve pain and function at intermediate term [SMDp -14.90 (95% CI:-22.40 to -7.39)]; 5) Mindfulness exercises (Qigong) minimally improved function but not global perceived effect at short term. Low evidence suggests 1) breathing exercises; 2) general fitness training; 3) stretching alone; and 4) feedback exercises combined with pattern synchronization may not change pain or function at immediate post treatment to short-term follow-up. Very low evidence suggests neuromuscular eye-neck co-ordination/proprioceptive exercises may improve pain and function at short-term follow-up.For chronic cervicogenic headache, moderate quality evidence supports static-dynamic cervico-scapulothoracic strengthening/endurance exercises including pressure biofeedback immediate post treatment and probably improves pain, function and global perceived effect at long-term follow-up. Low grade evidence supports sustained natural apophyseal glides (SNAG) exercises.For acute radiculopathy, low quality evidence suggests a small benefit for pain reduction at immediate post treatment with cervical stretch/strengthening/stabilization exercises.

AUTHORS' CONCLUSIONS

No high quality evidence was found, indicating that there is still uncertainty about the effectiveness of exercise for neck pain. Using specific strengthening exercises as a part of routine practice for chronic neck pain, cervicogenic headache and radiculopathy may be beneficial. Research showed the use of strengthening and endurance exercises for the cervico-scapulothoracic and shoulder may be beneficial in reducing pain and improving function. However, when only stretching exercises were used no beneficial effects may be expected. Future research should explore optimal dosage.

Chiropractic treatment approaches for spinal musculoskeletal conditions: a cross-sectional survey

Background

There are several chiropractic spinal manipulative technique systems. However, there is limited research differentiating the efficacy of these techniques. Additionally, chiropractors may also use ancillary procedures in the treatment of musculoskeletal pain, a variable that also needs to be considered when measuring the efficacy of chiropractic therapy. No data is currently available regarding the frequency of usage of chiropractic technique systems or ancillary procedures for the treatment of specific musculoskeletal conditions. Knowing which technique systems and ancillary procedures are used most frequently may help to direct future research. The aim of this research was to provide insight into which treatment approaches are used most frequently by Australian chiropractors to treat spinal musculoskeletal conditions.

Methods

Cross-sectional survey design. The survey was sent online to the members of the two main Australian chiropractic associations between 30^th June 2013 and 7^th August 2013. The participants were asked to provide information on treatment choices for specific spinal musculoskeletal conditions.

Results

280 respondents. Diversified manipulative technique was the first choice of treatment for most of the included conditions. Diversified was used significantly less in 4 conditions; cervical disc syndrome with radiculopathy and cervical central stenosis were more likely to be treated with Activator; flexion distraction technique was used almost as much as Diversified in the treatment of lumbar disc syndrome with radiculopathy and lumbar central stenosis. More experienced Australian chiropractors use more Activator and soft tissue therapy and less Diversified technique compared to their less experienced peers. The majority of responding chiropractors used ancillary procedures such as soft tissue techniques and exercise prescription in the treatment of spinal musculoskeletal conditions.

Conclusion

This survey provides information on commonly used treatment choices to the chiropractic profession. Treatment choices changed based on the region of disorder and whether neurological symptoms were present rather than with specific diagnoses. Diversified technique was the most commonly used spinal manipulative therapy, however, ancillary procedures such as soft tissue techniques and exercise prescription were also commonly utilised. This information may help direct future studies into the efficacy of chiropractic treatment for spinal musculoskeletal disorders.
