Brief Summary:

Primary Objective of this study: To assess experimental heat pain responses (pain intensity, pain unpleasantness, pain catastrophizing, emotional reactivity) in migraineurs vs. healthy controls.

The current tools of migraine pain measurement are inadequate to distinguish the overall burden of suffering, as there is an over reliance on a single numerical pain score to represent the entire pain experience. Measuring and targeting the affective component, in addition to the sensory component of pain, may capture this discrepancy in disease burden. The affective component of migraine pain may be just as important as the sensory component to target and measure since it significantly impacts outcomes, disability, and has therapeutic treatment implications.

Quantitative sensory testing (QST) is a robust lab paradigm (not a clinical experience) that delivers one painful noxious thermal stimuli and asks for simultaneous pain intensity and pain unpleasantness scores. By using this in the research, investigators will be able to differentiate the sensory (pain quality—what the pain feels like) from the affective (how awful/unpleasant the pain feels) components of experimental pain in normal controls vs. migrainuers.

No previous studies have evaluated differences in experimental pain intensity vs. pain unpleasantness in migraineurs vs. controls. As migraine pain uniquely involves many altered sensory phenomenon (e.g., photophobia, phonophobia), it cannot be assumed that responses to experimental pain in migraine will be the same as other clinical pain syndromes. Further, different clinical pain syndromes have distinct responses to pain intensity vs. pain unpleasantness.

Detailed Description:
Investigators will conduct a cross-sectional study in migraineurs (interictally, i.e., between migraine attacks) and healthy controls to compare responses to experimental heat pain intensity and unpleasantness and correlate these results to differences in emotional reactivity and pain catastrophizing.

Arm Intervention/treatment
Experimental: Migraine
Participants with migraines will complete one study visit where they will complete several questionnaires and will also complete Quantitative Sensory Testing (QST) Pain Measurements. They must be migraine-free during the visit and no migraine within 48 hrs of study visit
Other: Questionnaires
Before the experimental session, participants will use REDCap to complete several questionnaires used to assess outcomes.

Other: Quantitative Sensory Testing (QST) Pain Measurements
Investigators will administer noxious thermal stimulation to assess pain threshold temperatures and assess responses to pain on measures of pain intensity and pain unpleasantness

Active Comparator: Healthy Controls
Healthy Controls will complete one study visit where they will complete several questionnaires and will complete Quantitative Sensory Testing (QST) Pain Measurements.
Other: Questionnaires
Before the experimental session, participants will use REDCap to complete several questionnaires used to assess outcomes.

Other: Quantitative Sensory Testing (QST) Pain Measurements
Investigators will administer noxious thermal stimulation to assess pain threshold temperatures and assess responses to pain on measures of pain intensity and pain unpleasantness




Primary Outcome Measures :
  1. Heat Pain Intensity coefficient and intercept from stimulus response curve [ Time Frame: One visit ]
    Using the logarithmic equation: log (VAS pain ratings)=log (t - 35) * coefficient + intercept where t represents stimulus temperature, we will generate stimulus-response curves for each subject

  2. Heat Pain Unpleasantness coefficient and intercept from stimulus response curve [ Time Frame: One visit ]
    Using the logarithmic equation: log (VAS pain ratings)=log (t - 35) * coefficient + intercept where t represents stimulus temperature, we will generate stimulus-response curves for each subject

  3. Pain Catastophizing score [ Time Frame: One Visit ]
    Score on the Pain Catastrophizing instrument

  4. Difficulty in Emotions Regulation score [ Time Frame: One Visit ]
    Score on the Difficulty in Emotions Regulation score


Secondary Outcome Measures :
  1. Heat Pain Threshold Temperature [ Time Frame: One Visit ]
    Temperature of heat pain threshold

  2. Anxiety [ Time Frame: One Visit ]
    Score on the Generalized Anxiety Disorder (GAD-7) instrument

  3. Depression [ Time Frame: One Visit ]
    Score on the Patient Health related questionnaire-depression module (PHQ-9) instrument

  4. Mindfulness [ Time Frame: One Visit ]
    Score on the Five Factor Mindfulness (FFM) instrument

  5. Stress [ Time Frame: One Visit ]
