Meditation for Older Adults With Chronic Low Back Pain

Mindfulness-based Meditation for Older Adults With Chronic Low Back Pain Based on the Gut-brain Axis: A Pilot Randomized Controlled Trial

This pilot randomized controlled trial aims to recruit 66 community-dwelling older adults with chronic low back pain and follow up them for 8 weeks. This study aims to test the preliminary effect of a mindfulness-based meditation (MBM) intervention on pain and symptoms among community-dwelling older adults with chronic low back pain, and also to test the effect of the MBM intervention on the host Gut-Brain Axis (GBA).

Aim 1: to test the preliminary effect of a mindfulness-based meditation (MBM) intervention on pain and symptoms among community-dwelling older adults with chronic low back pain.

Hypothesis: We hypothesize that our active mindfulness-based meditation intervention will be feasible and acceptable to community-dwelling older adults with chronic low back pain and improve pain and symptoms to a greater extent than older adults randomized to a sham mindfulness-based meditation group.

Aim 2: to test the effect of the mindfulness-based meditation intervention on the host Gut-Brain Axis (GBA).

Hypothesis: We hypothesize that older adults randomized to the active mindfulness-based meditation intervention will have significantly improved compositional patterns and functional profiles of gut microbiota and increased pain-related cortical response measured by functional near-infrared spectroscopy (fNIRS) to a greater extent than older adults randomized to the sham mindfulness-based meditation group at 2-weeks post-intervention, and 8-weeks follow up.

Inclusion Criteria:
