Brief Summary

Although many adults with migraines use non-pharmacological treatment options, there is a lack of research on the use of many mind/body techniques specifically for headache. This research will further the understanding of the mechanisms, efficacy, and predictors of mind-body practices in adults with migraines.

Detailed Description

Migraine is a common and disabling pain condition. Affective/cognitive processes, such as pain catastrophizing and emotional reactivity, often play a major role in migraine pain and disability. These processes may be just as important to target as the sensory aspect given their impact on outcomes and disability. Because of this cognitive/affective load that builds over time in migraine, we hypothesize A) migraineurs perceive affective pain processing differently than non-migraineurs and B) mind/body therapies that target these factors may be especially beneficial and may differentially impact the affective component of migraine pain. Evidence shows that meditation decreases affective (e.g., pain unpleasantness) over sensory (e.g., pain intensity) response to experimental pain and reduces pain by engaging brain regions important for cognitive and affective modulation of pain. By measuring both experimental and clinical pain, the study team will be able to test these hypotheses.

Mindfulness Based Stress Reduction	Mindfulness Based Stress Reduction	Mindfulness Based Stress Reduction (MBSR) is a standardized course in mindfulness mediation and yoga.

Primary Outcome Measures

Name	Time	Method
Change in Frequency of Migraine Days Per Month From Baseline	Baseline and immediately post-intervention (12 weeks)	Change in frequency of migraine days from baseline: A migraine day is defined as a calendar day (00:00 to 23:59) when the patient reports 4 or more continuous hours of a moderate to severe headache (rating of 6-10 on 0-10 pain intensity scale) and/or they treated a headache with abortive medication; tracked with headache logs.

Secondary Outcome Measures

Name	Time	Method
Change in Migraine Severity-pain Intensity From Baseline to Week 12	baseline to Week 12	change in headache severity-pain intensity from baseline 4 weeks to weeks 8-12. For each headache attack, participants rated the pain intensity on a 0-10 scale (0, no pain sensation, 10 most intense pain sensation imaginable). We calculated the pain intensity of each headache attack and used a multivariable linear model framework controlling for baseline value of the outcome of interest, treatment group, cohort, and within participant variation via random effects, with significance based on the treatment group effect and phase interaction at .05 significance level.
Change in Headache Severity-pain Unpleasantness From Baseline to 12 Weeks	Baseline and 12 weeks	Change in headache severity on 0-10 scale (0, "not at all unpleasant" to 10, "most unpleasant imaginable") in pain unpleasantness from baseline 4 weeks to weeks 8-12 (tracked with headache logs).
Change in Headache-related Disability From Baseline	Baseline to Immediately post-intervention	Change in headache-related disability from baseline (Migraine Disability Assessment (MIDAS)-one month) Score range is 0-21+; 0 to 5: MIDAS grade I, little or no disability 6 to 10: MIDAS grade II, mild disability 11 to 20: MIDAS grade III, moderate disability 21 or higher: MIDAS grade IV, severe disability
Change in Frequency of Migraine Days From Baseline	3 months post-intervention	Change in frequency of migraine days from baseline: A migraine day is defined as a calendar day (00:00 to 23:59) when the patient reports 4 or more continuous hours of a moderate to severe headache (rating of 6-10 on 0-10 pain intensity scale) and/or they treated a headache with abortive medication; tracked with headache logs
Percent Change in Response Score to Experimental Heat Pain on Pain Unpleasantness Measure From Baseline (0-10) Visual Analogue Scale (VAS Scale) From Baseline to 12 Weeks	Baseline to week 12	Using a 10 cm sliding visual analogue scale, participants quantified unpleasantness (from "not at all unpleasant" to "most unpleasant imaginable"). Participants rated perceived pain unpleasantness at baseline and at 12 weeks for each of 6 measures at 49 °C. A multivariable linear mixed model was used to model the percent change from baseline in perceived pain intensity at each visit for each of 6 measures at 49 °C. Change scores were modeled as a function of treatment group and visit, controlling for baseline. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). Ask the patient to rate their current level of pain by placing a mark on the line.

Change in Headache Severity-pain Intensity From Baseline to Week 12	Baseline and 12 weeks	Modeled change in headache severity-pain intensity from baseline 4 weeks to weeks 8-12. For each headache attack, participants rated the pain intensity on a 0-10 scale (0, no pain sensation, 10 most intense pain sensation imaginable). Higher scores mean a worse outcome in terms of pain intensity.

A multivariable linear mixed model was used to model the percent change from baseline in perceived pain intensity at each visit for each of 6 measures at 49 °C. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). Ask the patient to rate their current level of pain by placing a mark on the line.
