[Effectiveness of physiotherapeutic treatment interventions on pain intensity, duration, frequency, and quality of life of patients with migraine : A systematic review]

BACKGROUND

According to the current guidelines preventive treatment of migraine should consist of a combination of pharmacological and nonpharmacological forms of treatment. Physiotherapeutic modalities could be an option for nonpharmacological migraine management.

OBJECTIVE

The aim was to assess the efficacy of physiotherapeutic interventions on pain intensity, duration and frequency as well as the quality of life of patients with migraine.

METHODS

A systematic literature search was carried out in four databases: the Physiotherapy Evidence Database (PEDro), Web of Science, Medline via PubMed and the Cochrane Library. Randomized controlled trials (RCTs) that were published up to the end of July 2021 and examined the effectiveness of physiotherapeutic treatment in migraine patients were eligible for inclusion. Studies that did not examine an adult population, interventions not carried out by a physiotherapist or not reporting an appropriate outcome were excluded. The assessment of the risk of bias was carried out with the revised version of the Cochrane risk of bias tool 2.0. A descriptive and quantitative synthesis using mean difference with a random effects model and 95% confidence intervals were used.

RESULTS

The present review included 13 RCTs reporting on a total of 595 patients. The risk of bias was high for four studies, low for two studies and the remaining seven studies had some concerns. The interventions examined were multimodal physiotherapy programs, various mobilization techniques, trigger point therapy, manual lymphatic drainage, massage and various stretching techniques. All interventions examined had a significantly positive effect on the selected parameters compared to the baseline values. Especially combinations of various physiotherapeutic modalities showed clinically relevant results.

CONCLUSION

The evidence suggests that multimodal physiotherapy treatment is a good supplement to medication and should therefore be considered as a nonpharmacological treatment for patients with migraine; however, further RCTs with a low risk of bias are necessary in order to confirm the effectiveness with high quality evidence.

Effectiveness of a manual therapy protocol based on articulatory techniques in migraine patients. A randomized controlled trial

BACKGROUND

Physiotherapy is used as a non-pharmacological treatment for migraine. However, controversy exists over whether articulatory manual techniques are effective in some aspects related to migraine.

OBJECTIVES

To assess the effectiveness of a manual therapy protocol based on articulatory techniques in pain intensity, frequency of episodes, migraine disability, quality of life, medication intake and self-reported perceived change after treatment in migraine patients.

DESIGN

Randomized controlled trial.

METHODS

Fifty individuals with migraine were randomized into the experimental group, which received manual therapy based on articulatory techniques (n = 25), or the placebo group (n = 25). The intervention lasted 4 weeks and included 4 sessions. Patients were assessed before (T1), after (T2) and at a one-month follow-up following the intervention (T3). The instruments used were the Migraine Disability Assessment (MIDAS) questionnaire, the Short Form-36 Health Survey (SF-36), the medication intake and The Patients' Global Impression of Change scale.

RESULTS

In comparison with placebo group, manual therapy patients reported significant effects on pain intensity at T2 (p < 0.001; d = 1.15) and at T3 (p < 0.001; d = 1.13), migraine disability at T3 (p < 0.05; d = 0.69), physical quality of life at T2 (p < 0.05; d = 0.72), overall quality of life at T2 (p < 0.05; d = 0.60), decrease in medication intake at T2 (p < 0.001; d = 1.11) and at T3 (p < 0.05; d = 0.77) and self-reported perceived change after treatment at T2 and T3 (p < 0.001). No serious adverse events were reported.

CONCLUSIONS

The application of a manual therapy protocol based on articulatory techniques reduced pain intensity, migraine disability, and medication intake, while improving quality of life in patients with migraine.

The global summit on the efficacy and effectiveness of spinal manipulative therapy for the prevention and treatment of non-musculoskeletal disorders: a systematic review of the literature

Background

A small proportion of chiropractors, osteopaths, and other manual medicine providers use spinal manipulative therapy (SMT) to manage non-musculoskeletal disorders. However, the efficacy and effectiveness of these interventions to prevent or treat non-musculoskeletal disorders remain controversial.

Objectives

We convened a Global Summit of international scientists to conduct a systematic review of the literature to determine the efficacy and effectiveness of SMT for the primary, secondary and tertiary prevention of non-musculoskeletal disorders.

Global summit

The Global Summit took place on September 14–15, 2019 in Toronto, Canada. It was attended by 50 researchers from 8 countries and 28 observers from 18 chiropractic organizations. At the summit, participants critically appraised the literature and synthesized the evidence.

Systematic review of the literature

We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, the Cumulative Index to Nursing and Allied Health, and the Index to Chiropractic Literature from inception to May 15, 2019 using subject headings specific to each database and free text words relevant to manipulation/manual therapy, effectiveness, prevention, treatment, and non-musculoskeletal disorders. Eligible for review were randomized controlled trials published in English. The methodological quality of eligible studies was assessed independently by reviewers using the Scottish Intercollegiate Guidelines Network (SIGN) criteria for randomized controlled trials. We synthesized the evidence from articles with high or acceptable methodological quality according to the Synthesis without Meta-Analysis (SWiM) Guideline. The final risk of bias and evidence tables were reviewed by researchers who attended the Global Summit and 75% (38/50) had to approve the content to reach consensus.

Results

We retrieved 4997 citations, removed 1123 duplicates and screened 3874 citations. Of those, the eligibility of 32 articles was evaluated at the Global Summit and 16 articles were included in our systematic review. Our synthesis included six randomized controlled trials with acceptable or high methodological quality (reported in seven articles). These trials investigated the efficacy or effectiveness of SMT for the management of infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine. None of the trials evaluated the effectiveness of SMT in preventing the occurrence of non-musculoskeletal disorders. Consensus was reached on the content of all risk of bias and evidence tables. All randomized controlled trials with high or acceptable quality found that SMT was not superior to sham interventions for the treatment of these non-musculoskeletal disorders. Six of 50 participants (12%) in the Global Summit did not approve the final report.

Conclusion

Our systematic review included six randomized clinical trials (534 participants) of acceptable or high quality investigating the efficacy or effectiveness of SMT for the treatment of non-musculoskeletal disorders. We found no evidence of an effect of SMT for the management of non-musculoskeletal disorders including infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine. This finding challenges the validity of the theory that treating spinal dysfunctions with SMT has a physiological effect on organs and their function. Governments, payers, regulators, educators, and clinicians should consider this evidence when developing policies about the use and reimbursement of SMT for non-musculoskeletal disorders.
