In the United States, 12% of adults suffer from migraines. Migraines are categorized as episodic or chronic (CM). CM is less common than episodic, with a prevalence of 2%, but far more debilitating, with three times the annual per capita cost, putting the total U.S. direct and indirect cost estimate of CM at $15.5 billion dollars per year. Compared to patients with episodic migraine, those with CM have a lower quality of life (QoL) and higher utilization of primary and emergency care. CM has only two prophylactic pharmacologic treatment options with efficacy demonstrated through randomized, placebo-controlled trials. One is Topiramate, whose side effects, including fatigue, dizziness, mood changes and suicidal ideation, can compromise patients' QoL and adherence rate to this treatment, which has been estimated as under 25%. The other is onabotulinumtoxinA, whose side effects, including neck pain, eyelid ptosis and worsening headaches, are reported in over 25% of users. Due to these high frequency, debilitating side effects, ¬there is an urgent need to develop effective CM treatments with low side-effect profiles.~Osteopathic manipulative treatment (OMT) has been reported to improve episodic and CM symptoms without major side effects. Improvements with OMT include decreased Headache Impact Test (HIT-6) scores, fewer headache days per month and decreased medication use. While promising, these studies have significant limitations, such as small sample sizes and high risk of bias. Further, even higher quality OMT studies rely on the treating physician to select from among several OMT treatment techniques, rather than using a standardized treatment procedure. Together, these limitations led the most recent literature assessment to conclude that, more study is needed before manipulative therapies can be confidently recommended to prevent and treat headaches. To overcome these limitations, OMT studies for the treatment of CM should apply rigorous methods, including standardized treatment procedures.~The investigators have developed a standardized OMT procedure to treat CM. The procedure is repeated every two weeks over a ten week period. Over the past five years it has been successfully used to treat 50 patients with CM in a single family physician's practice. Among the treated patients, 40 reported improved symptoms, and none reported adverse side effects. However, the procedure has not been formally evaluated using rigorous research methods.~The specific objectives of this pilot study are to evaluate the feasibility and acceptability of the standardized OMT procedure for CM, and gather preliminary data on its potential efficacy when implemented in a primary care setting. The central hypothesis is that the standardized myofascial release OMT procedure will improve symptoms of CM as measured by improvement in HIT-6, Migraine Disability Assessment (MIDAS), Migraine-Specific Quality-of-Life Questionnaire (MSQ), and self-reported and electronic health record (EHR) medication usage and healthcare utilization. This hypothesis is supported by the investigators' anecdotal clinical success using this approach. The specific aims of this study are:~Aim 1: Assess the feasibility of systematically identifying and treating patients with the standardized OMT procedure within the Penn State Health medical system. Feasibility will be measured by the investigators' ability to identify and enroll CM patients in this study. The investigators will enroll 20-40 adult patients with CM who do not have common confounders. This data will inform the recruitment strategy of a future randomized clinical trial (RCT).~Aim 2: Assess the acceptability of the standardized OMT procedure. Acceptability will be measured by patient-reported satisfaction and perceived benefit, completion rate and adverse events or side-effects. This data will inform the sample size calculation of a future RCT.~Aim 3: Assess the preliminary effectiveness of the standardized OMT procedure. Efficacy will be measured by improvement in HIT-6, MIDAS, and MSQ scores; patient-reported headache frequency, medication usage, and healthcare utilization surveys; and medication and healthcare utilization documented in the EHR. This data will provide estimates of effect size to better inform the sample size calculation of a future RCT.
This study evaluates a standardized osteopathic manipulative therapy (OMT) as a treatment for chronic migraine headaches. It will determine the feasibility of enrolling patients in standardized osteopathic manipulative therapy trials, the acceptability of this specific treatment to patients, and evaluate its preliminary effectiveness.
