The purpose of this study is to see if mindfulness, a form of mental training, or listening to a book alters brain activation in response to raising your leg that may produce the feeling of pain. A technique called functional magnetic resonance imaging (fMRI) allows scientists to determine which parts of the brain are active during a particular task. This study will provide new information about how mindfulness affects the brain.
To determine if mindfulness meditation-induced reductions in chronic low back pain (cLBP) patients will be associated with greater anterior insula (aINS), orbitofrontal cortex (OFC), subgenual anterior cingulate cortex (sgACC), and/or thalamic deactivation when compared to rest, the sham-mindfulness meditation and the book-listening control groups. One-hundred and twenty individuals will be randomized to a mindfulness meditation (n=40), non-mindfulness meditation (n=40) and book-listening-control (n=40). Each participants will be administered noxious heat and the chronic low back pain evoking, straight leg raise test during fMRI.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| mindfulness group | Experimental | Study volunteers will participate in a six-session meditation training regimen. In brief, subjects will be taught that perceived sensory events are "momentary" and "fleeting" and do not require further evaluation. There will be an emphasis on breath focus and altering one's perspective of discursive sensory events. This intervention has been found to reliably attenuate the subjective experience of pain. |
|
| non-mindfulness group | Sham Comparator | Study volunteers will participate in a six-session meditation training regimen. In brief, subjects will be taught to take deep breaths and relax. |
|
| book-listening | Active Comparator | Study volunteers will listen to an audio recording of the Natural History of Selborne across each session.This 6 session intervention is meant to provide the control attention to the facilitator, room setting, social support, conditioning, and the time elapsed during the other respective interventions. We do not expect that this group will demonstrate significant cerebral blood flow changes as a function of the intervention. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| mindfulness training | Behavioral | A well-validated brief mindfulness-based mental training regimen [20 min/session(s)] will be used to teach patients to independently practice mindfulness. Participants will be asked to close their eyes acknowledge distracting thoughts and feelings. |
| Measure | Description | Time Frame |
|---|---|---|
| Cerebral Blood Flow (average blood perfusion; mL blood/100 grams tissue/minute) | Changes in cerebral blood flow will be assessed during pseudo continuous arterial spin labeling fMRI during their respective manipulations. | There will be up to 2 fMRI sessions (Visit 2, and 9). Active enrollment provides up to 8 weeks to complete all study interventions, scans, and assessments. |
| Measure | Description | Time Frame |
|---|---|---|
| Visual Analog Scale Pain Ratings | Changes in visual analog scale (VAS) pain ratings will be assessed in response to the straight leg raise test and lying supine in the MRI scanner. Psychophysical Assessment of Pain: As previously in all of our previous pain studies, pain intensity and unpleasantness ratings will be assessed with a Visual Analog Scale. These scales 1) provide reliably separate assessment of experimental and clinical pain intensity and unpleasantness, 2) are internally consistent, and 3) approximate ratio scale measurement accuracy. The minimum rating ("0") is designated as "no pain" whereas the maximum ("10") is labeled as "most intense imaginable" or "most unpleasant imaginable". Higher numbers correspond to higher perceived pain |

|---|---|---|
| Social Connectedness Scale | This is a 20-item assessment designed to measure social connectedness, an attribute of the self that reflects cognitions of enduring interpersonal closeness with the social world, in participants. Higher scores on the Social Connectedness Scale reflect a stronger sense of social connectedness, there are no sub-scales. The minimum score is 20 and the maximum score is 120. | There will be up to 2 fMRI sessions (Visit 2, 9). Active enrollment provides up to 8 weeks to complete all study interventions, scans, and assessments. |

This intervention study will utilize an unbiased randomized study design. Pain intensity and pain unpleasantness ratings will be assessed using before and after all sessions where low back pain is induced. Study volunteers will be randomized and subsequently participate in a six session mindfulness meditation, non-mindfulness meditation or book-listening control regimen. Study volunteers will be required to complete two MRI scans over the course of the study.
