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

Manual physical therapy for neck disorders: an umbrella review

INTRODUCTION

Neck pain is a common musculoskeletal disorder, with a prevalence rate (age-standardized) of 27.0 per 1000 in 2019. Approximately 50-85% of individuals with acute neck pain do not experience complete resolution of symptoms, experiencing chronic pain. Manual therapy is a widely employed treatment approach for nonspecific neck pain (NSNP), cervical radiculopathy (CR) and cervicogenic headaches (CGH). This umbrella review synthesized systematic reviews examining manual physical therapy for individuals with cervical disorders.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed with Prospero registration (CRD42022327434). Four databases were searched from January 2016 to May 2023 for systematic reviews with or without meta-analysis examining manual therapy for individuals with neck pain of any stage. Interventions included any manual physical therapy of the cervical or thoracic spine as well as neuromobilization of the upper quarter. Primary outcomes included pain and disability. Two reviewers screened for eligibility and completed data extraction. Methodological quality was assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2) tool.

RESULTS

A total of 35 SRs were included: 15 NSNP, 7 cervical radiculopathy, 9 CGH and 4 samples with combined diagnoses. AMSTAR 2 ratings of the SRs support high confidence in results for 10 reviews, moderate confidence in 12 reviews and low to critically low confidence in 13 reviews. For NSNP, there was high confidence in the results showing manual therapy combined with exercise was superior to either treatment in isolation. In cervical radiculopathy, neural mobilization, distraction, soft tissue treatment and mobilization/manipulation to cervical and thoracic spine were supported with moderate confidence in results. For CGH, there was high confidence in the results supporting the use of cervical spine mobilization/manipulation, soft tissue mobilization, and manual therapy combined with exercise. Original authors of SRs reported varying quality of primary studies with lack of consistent high quality/low risk of bias designs.

CONCLUSION

Manual therapy plus exercise, cervical or thoracic mobilization and manipulation, neuromobilization, and other types of manual therapy were supported as effective interventions in the management of pain and disability for individuals with NSNP, CGH, or CR in the short-term.

Combined and isolated effects of workstation ergonomics and physiotherapy in improving cervicogenic headache and work ability in office workers: a single-blinded, randomized controlled study

Objective

The objective of the study is to compare and investigate the combined and individual effects of workstation ergonomics, physiotherapy and patient education in improving CgH headaches and work ability in office workers.

Methods

96 eligible CgH participants were divided into the ergonomics modifications group (EMG; n = 24), physiotherapy group (PTG; n = 24), and ergonomics modifications combined with physiotherapy group (EPG; n = 24) and education control group (CNG; n = 24), the participants received the respective treatment for 4 weeks. Primary (CgH frequency) and secondary (CgH pain intensity, CgH disability, flexion rotation test (right and left), neck disability index and work ability) scores were measured. The effects of treatment at various intervals were analyzed with a 4 × 4 linear mixed model analysis (LMM) between treatment groups and time intervals.

Results

Four weeks following training EPG group showed more significant changes in primary outcome CgH frequency; 4.6 CI 95% 3.63 to 5.56 when compare to control group. The same gradual improvement was noticed at 8 weeks 8.2 CI 95% 7.53 to 8.86 and at 6 months follow up 11.9 CI 95% 11.25 to 12.54 when compare to other groups (p = 0.001) which is statistically 52.97% improvement. Similar improvements can be seen in the secondary outcome measures such as CgH pain intensity, CgH disability, flexion rotation test (right and left), neck disability index and work ability in EPG group than the EMG, PTG, and CNG groups (p = 0.001) at 4 weeks, 8 weeks and at 6 months' follow-up.

Conclusion

This study observed that the workstation ergonomics and physiotherapy group experienced significantly more improvements in cervicogenic headache patients.

What is the Status Quo of Patient-Centred Physiotherapy Management of People with Headache within a Biopsychosocial Model? - A Narrative Review

PURPOSE OF REVIEW

Patient-centred care (PCC) is deemed essential in the rehabilitation of musculoskeletal pain. Integrating such care within a biopsychosocial framework, enables to address all facets of the individual pain experience, and to manage the individual instead of the condition. This narrative review describes the status quo of PCC physiotherapy management of people with headache within a biopsychosocial model. PubMed, EMBASE, Web of Science, Scopus were searched (update 07.05.2024). The search-query comprised terminology relating to "headache", "patient-centred", "biopsychosocial", "physiotherapy". Additional eligibility criteria were reviews, trials, cohort, case report, case-control studies in English, Dutch, French.

RECENT FINDINGS

Gaps are exposed in patient-centred physiotherapy management of migraine, tension-type headache, and cervicogenic headache. While a biopsychosocial approach is advised to manage migraine and tension-type headache, its use in clinical practice is not reflected by the literature. A biopsychosocial approach is not advised in cervicogenic headache. Psychosocial-lifestyle interventions are mainly delivered by health-care providers other than physiotherapists. Additionally, psychologically-informed practice is barely introduced in physiotherapy headache management. Though, managing the social context within a biopsychosocial framework is advised, the implementation by physiotherapists is unclear. Comparable conclusions apply to PCC. PCC is recommended for the physiotherapy management of primary and secondary headache. Such recommendation remains however theoretical, not reaching clinical implementation. Yet, a shift from the traditional disease-centred model of care towards PCC is ongoing and should be continued in physiotherapy management. With this implementation, clinical and economical studies are needed to evaluate its effectiveness.

Therapeutic Patient Education as Part of the Physiotherapy Management of Adults with Headache: A Scoping Review

PURPOSE OF REVIEW

Physiotherapy interventions for headache mostly include exercise and manual therapy. Yet, the complex nature of headache, sometimes characterized by symptoms of facilitated central pain mechanisms, demands an individualized approach in which therapeutic patient education could be supportive. This scoping review aimed to summarize the position of therapeutic patient education within the physiotherapy management of adults with headache. PubMed, EMBASE, Web of Science, and Scopus were searched. The search-query comprised terminology relating to "headache", "education", and "physiotherapy". Eligibility criteria were: adults with headache, interventions including education within the domain of physiotherapy, reviews, clinical trials, cohort, case report, case-control studies.

RECENT FINDINGS

Eleven publications were included from the 281 retrieved publications. These publications were clinical trials (n = 4), reviews (n = 4), case-reports (n = 2), and a guideline (n = 1). Type of headaches studied were migraine (n = 3), post-traumatic headache (n = 2), tension-type headache (n = 2), cervicogenic headache (n = 1), primary headaches (n = 1), chronic daily headache (n = 1), and mixed migraine-cervicogenic headache (n = 1). Education seems an umbrella-term for postural education, lifestyle advice, and pain education. Three themes emerged across the publications: handling headache triggers (migraine, post-traumatic headache), promoting active lifestyle (post-traumatic headache, chronic daily headache, migraine), evaluating posture (post-traumatic headache, chronic daily headache, tension-type headache, cervicogenic headache). All publications recommended education in the management of headache. Only one (of the 11 included) publication described the educational program and determined its efficacy. Based on this scoping review, therapeutic patient education seems supported within physiotherapy management of headache. However, it is unclear how such education is tailored to the specific needs of the individual, the headache subtype, or when it should be added to physiotherapy management of headache.

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.

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.

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.
