Rheumatoid Arthritis
Conditions
Brief summary
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.
Interventions
This will be a brief meditation intervention involving guided breathing and/or attention exercises. Further information is withheld to preserve blinding.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Lateral Orbital Frontal Cortex Activation | 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 | 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. |

Outcome results
Lateral Orbital Frontal Cortex Activation
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.
Time frame: Measured at the post-Intervention time point during an MRI scan, approximately 60 minutes.
Population: This outcome was not assessed because it was intended for comparison with a treatment arm (mindful breathing) that was dropped from the study due to COVID-19 delays. No data was collected.
Nucleus Accumbens Activation
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.
Time frame: Measured at the post-Intervention time point during an MRI scan, approximately 60 minutes
