简要总结
The purpose of this study is to determine the neural mechanisms supporting meditation-based pain relief in rheumatoid arthritis (RA) patients. The scientific premise is that RA patients' use of different meditation practices during noxious thermal stimulation will alter neural function in brain areas associated with pain, evaluation, and emotional appraisal. The investigators will randomize RA patients to a brief 4-session course of Intervention A (n=20) or Intervention B (n=20). At post-intervention, participants will undergo functional MRI (fMRI) using a perfusion-based arterial spin labeling (ASL) technique during noxious thermal stimulation to determine if the meditation practices differentially alter neural function during noxious thermal stimulation.

结局指标
主要结局
Lateral Orbital Frontal Cortex Activation
时间窗: Measured at the post-Intervention time point during an MRI scan, approximately 60 minutes.
Activation in the Lateral Orbital Frontal Cortex will be quantitatively measured as the difference in cerebral blood flow (CBF) response during noxious thermal stimulation while participants actively practice Intervention A in the scanner, compared to the CBF response during noxious thermal stimulation while participants rest. The unit of measure will be milliliter per 100 gram brain tissue per minute.
Nucleus Accumbens Activation
时间窗: Measured at the post-Intervention time point during an MRI scan, approximately 60 minutes
Activation in the Nucleus Accumbens will be quantitatively measured as the difference in cerebral blood flow (CBF) response during noxious thermal stimulation while participants actively practice Intervention B in the scanner, compared to the CBF response during noxious thermal stimulation while participants rest. The unit of measure will be milliliter per 100 gram brain tissue per minute (ml/100g/min). There is no normal range for this measure.
