This study compares how different types of touch found in massage therapies impact pain perception, and whether these effects differ in individuals with and without chronic pain. This study also examines psychological factors that may predict differences in touch perception in individuals with chronic pain. This research will improve our understanding of whether and how massage therapies can benefit pain and health, and whether this differs in people who suffer from chronic pain.
