Clinical Trial Summary

This study will highlight and validate chiropractic spinal manipulative therapy (CSMT) for migraine. If the method proves to be effective, it will provide a new non-pharmacological treatment option for migraine. This is especially important since some migraineurs do not tolerate acute and/or prophylactic medicine, due to side effects or contraindications due to comorbidity of other diseases while others do not have effect. Thus, alternative treatment options are warranted. The applied methodology of the study will aim towards the highest possible research standards. This international study is a collaboration between Akershus University Hospital, University of Oslo (UiO), Norway and Macquarie University, Australia. The multidisciplinary professional backgrounds are physiotherapy, chiropractic and medicine. By increasing the methodological quality of the investigators research to a very high level, the investigators see the method to work as a guide to increase the quality of chiropractic research in the future, as previous randomized clinical trials (RCTs) of migraine used methodology showing room for improvement.

Description:

Migraine is characterized by a unilateral pulsating moderate/severe headache which is aggravated by routine physical activity, and is accompanied by photo- and/or phonophobia, nausea and sometimes vomiting. Migraine exists in two forms, migraine without aura (MO) and migraine with aura (MA). Aura is reversible neurological disturbances of the vision, sensory and/or speech, which occur prior to the headache. The aura symptoms show intra-individual variations. The origin of migraine pain is still debated, since the origin of painful impulses in the trigeminal nerve is still uncertain. Some argues for central and other argues for peripheral mechanisms. Extracranial pain sensitive structures include skin, muscles, arteries, periosteum and joints. The skin is sensitive to all usual forms of pain stimuli, while especially temporal and neck muscles may be sources for pain and tenderness in migraine. Similarly is the frontal supraorbital, superficial temporal, posterior and occipital arteries sensitive to pain. It has been hypothesize that CSMT might relieve migraine due to stimulation of different mechanoreceptors in the neck such as the zygapophyseal joints, intervertebral discs and neck muscles. Numerous studies of manipulations have been conducted, but all had one or more methodological shortcomings, i.e. failure to specify diagnostic criteria, inadequate or no randomization procedure, lack of control, lack of patient blinding, lack of specified primary and secondary end points and shortcomings of statistical evaluation of the results. A few RCTs suggest that CSMT using diversified technique is an effective therapy for migraine. The diversified technique is used by 91% of chiropractors, and include a collections of procedures, hence the name diversified. It focuses on inter-segmental pretension (soft tissue tension) prior to the delivery of high velocity low amplitude (HVLA) adjustment. The Gonstead method is used by 59% of chiropractors and is also based on HVLA, but a major difference is the minimal usage of rotation in all adjustments in contrast to the diversified technique. The Gonstead method is considered safe, since severe adverse reactions have not been encountered. No studies have previously investigated the efficacy of the Gonstead method for migraine, although research in other CSMT modalities has been recommended.

Study hypothesis CSMT using the Gonstead method reduces days with migraine by at least 25% as compared to placebo (sham manipulation, i.e. broad non-specific contact, non-directional, low velocity and low amplitude) and no intervention (control group).

The RCT is single blinded, placebo-controlled trial of CSMT using the Gonstead method vs. sham manipulation and control group. If the treatment shows to be effective, the participants whom receive sham manipulation or control will be offered true intervention after the follow-up period and free of charge. This study will follow the recommendations set by the clinical trial guidelines from the IHS, while the methodological quality control will in general follow previous suggested criteria and the CONSORT statements.

Patients will be recruited through Akershus University Hospital, Norway as well as through media advertising in Akershus and Oslo County. The diagnoses are set by a chiropractor and a neurologist with experience in headache. In accordance with good clinical practice, all patients will receive written and oral information about the project and will be informed about the harms and benefits as well as adverse reaction of the intervention. A total of 90 participants need to be recruited to the clinical trial.

The clinical trials consist of three stages: Run-in, intervention (treatment) and follow-up.

One month of baseline data collection where participants will fill-in a diagnostic headache diary. Baseline demographics and clinical characteristics will be presented in tables with mean and standard deviation (SD) for each group.

As age and genders may plays a role, participants will be subdivided into four subgroups by age and gender prior to the concealed group allocation and restricted randomization by drawing prepared sealed lots. Each lot includes three different interventions, i.e active treatment, sham manipulation and control group. The first three participants will draw from the same lot until all three interventions are used. The next lot with three interventions is then followed by the next three participants; each participant will only receive one intervention.

The RCT will be conducted by an experienced chiropractor. Active treatment consists of CSMT using the Gonstead method. A specific contact, high velocity, low amplitude, short lever, with no recoil post adjustment directed to spinal biomechanical dysfunction diagnosed by standard chiropractic tests.

Follow-up at 3, 6 and 12 months post-treatment. During this period participants continue to fill in a diagnostic headache diary. The control group will also be included in this phase of the study.

The data will be analyzed with SPSS using standard statistical techniques.

The investigators based the calculation of sample size on migraine days from recent group comparison studies of topiramate. The investigators calculated that a sample size of 16 patients was required in each group to detect a difference in mean reduction in monthly migraine headache days of 2.5 with 80% power, with p=0.05 as level of significance, and assuming a common SD of 2.5 for active treatment and broad-based treatment groups.

Insurance is through "The Norwegian System of Compensation to Patients" (NPE) which is an independent national body, set up to process compensation claims from patients who have suffered an injury as a result of treatment under the Norwegian health service.

The Regional Committee for Medical Research Ethics (REK) in Norway and Norwegian Social Science Data Services approved the full PhD research protocol. The declaration of helsinski is followed.
