Yoga Nidra is a scripted mind-body intervention (MBI) that uses guided relaxation technique in a reproducible sequence of mechanisms that naturally produce a parasympathetic response. This is a randomized controlled trial in which participants will be randomly assigned to one of three interventions: 1) yoga nidra (Yoga Nidra Script Basic), 2) yoga nidra with pain acceptance (Yoga Nidra Acceptance Intention), 3) yoga nidra with pain acceptance and Explicit Motor Imagery (Yoga Nidra Acceptance Intention and Visualization).
