The impact of myofascial release and stretching techniques on the clinical outcomes of migraine headache: A randomized controlled trial

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

Objective

To assess the effectiveness of myofascial release (MFR) techniques on the intensity of headache pain and associated disability in patients with tension-type headache (TTH), cervicogenic headache (CGH), or migraine.

Design

A systematic review and meta-analysis.

Methods

Eight databases were searched on September 15, 2023, including PubMed, Scopus, Web of Science, CINAHL, Cochrane Library, Embase, CNKI, and Wanfang Database. The risk of bias was evaluated utilizing the Cochrane Risk of Bias 2 (RoB 2) tool.

Results

Pooled results showed that MFR intervention significantly reduces pain intensity [SMD = -2.01, 95% CI (-2.98, -1.03), I2 = 90%, P < 0.001] and improves disability [SMD = -1.3, 95% CI (-1.82, -0.79), I2 = 74%, P < 0.001]. Subgroup analysis based on the type of headache revealed significant reductions in pain intensity for CGH [SMD = -2.01, 95% CI (-2.73, -1.29), I2 = 63%, P < 0.001], TTH [SMD = -0.86, 95% CI (-1.52, -0.20), I2 = 50%, P=0.01] and migraine [SMD = -6.52, 95% CI (-8.15, -4.89), P < 0.001] and in disability for CGH [SMD = -1.45, 95% CI (-2.07, -0.83), I2 = 0%, P < 0.001]; TTH [SMD = -0.98, 95% CI (-1.32, -0.65), I2 = 0%, P < 0.001] but not migraine [SMD = -2.44, 95% CI (-6.04, 1.16), I2 = 97%, P=0.18].

Conclusion

The meta-analysis results indicate that MFR intervention can significantly alleviate pain and disability in TTH and CGH. For migraine, however, the results were inconsistent, and there was only moderate quality evidence of disability improvement for TTH and CGH. In contrast, the quality of other evidence was low or very low.

The Role of Manual Therapies in the Treatment of Headache Disorders

PURPOSE OF REVIEW

A comprehensive headache treatment plan typically requires both medication and non-medication treatment strategies. Manual therapies offer another therapeutic approach to headache treatment. This article reviews the evidence for manual therapies in the treatment of headache disorders.

RECENT FINDINGS

Current evidence shows potential benefit from myofascial trigger point injections, myofascial release, and massage for the treatment of various headache types. There is also evidence for strain counterstrain technique, ischemic compression, and spinal manipulative therapies for cervicogenic headache. Although larger randomized clinical trials are necessary for many of these modalities, recent findings show that manual therapies could be an important tool for the treatment of some headache disorders.

Does the Intensity of the Headache Differ According to the Level of Neck Disability in Chronic Migraine Patients?

Chronic migraine (CM) patients who report a high frequency and intensity of headaches also report neck pain (NP) and neck disability (ND) in neck activities that require stability. In this context, CM patients may report different headache intensities at different levels of ND. Our aim in this study is to investigate whether the intensity of headaches differs according to the level of ND in CM patients. Headache intensity and NP intensity were evaluated with the Visual Analog Scale (VAS), and ND was evaluated with the Neck Disability Index (NDI). A total of 142 patients who met the inclusion criteria were included in the study. The mean age was 53.24 ± 12.08 years. The median number of monthly headache days was 20. According to VAS, the median headache intensity was 10(4-10) cm and the median of NP intensity was 9(1-10) cm. The mean NDI was 28.45 ± 10.28. There was a difference in headache intensity between mild and severe disability levels (p = 0.007, Z = -3.289); headache intensity between mild and complete disability levels (p = 0.000, Z = -4.421); and headache intensity between moderate and complete disability levels (p = 0.004, Z = -2.212). Although the difference in headache intensity between ND levels is small, a median increase of 2 cm in headache intensity at mild ND levels may result in complete ND. A median increase of 1 cm in headache intensity at the moderate ND level may cause complete disability in the neck. According to our results, the intensity of headaches of CM patients differed according to the level of ND. We consider our results to be clinically important in this context.

Neck-specific strengthening exercise compared with placebo sham ultrasound in patients with migraine: a randomized controlled trial

Background

Migraine patients have musculoskeletal disorders and pain in the cervical. And, despite the pathophysiology demonstrating the relationship between migraine and the cervical spine, the effectiveness of craniocervical exercises in these patients has not been verified. So, the aimed of this study was verify the effectiveness of craniocervical muscle-strengthening exercise (CMSE) in reducing the frequency and intensity of headache in migraine patients. 

Methods

A two-armed, parallel-group randomized controlled trial with a 3-month follow-up was performed. For eight weeks, the volunteers in the intervention group (n = 21) performed a protocol of CMSE, while those in the sham ultrasound group (n = 21) received the application of disconnected therapeutic ultrasound in the upper trapezius and guideline for home-stretching. The primary outcomes were the frequency and intensity of the headache. The secondary outcomes were questionnaires about migraine and neck disability, and satisfaction with the treatment, cervical range of motion, the pressure pain threshold, craniocervical flexion test (CCFT), cervical muscle strength and endurance test, and the cervical muscle activity during the physical tests.

Results

No differences were observed for the changes observed in primary outcomes after eight weeks and at the 3-months follow up (p > 0.05). For the secondary outcomes, craniocervical exercises improved the sensitivity of the frontal muscle (p = 0.040) and promoted a reduced amplitude of muscle activity of the anterior scalene and upper trapezius in the last stages of CCFT (p ≤ 0.010). There was also reduced muscle activity of the anterior scalene and splenius capitis in the endurance test (p ≤ 0.045), as evaluated by surface electromyography.

Conclusion

CMSE were insufficient in reducing the frequency and intensity of headache, improving the performance of the cervical muscles, or reducing migraine and neck pain-related disabilities. This was found despite a decreased electromyographic activity of the cervical muscles during the last stages of CCFT and increased median frequency during the endurance test.
