"Definitions of CAM differ. For example, a study of CAM in hospices identified practices as diverse as massage therapy, supportive group therapy, music therapy, pet therapy, and guided imagery or relaxation, not all of which are usually associated with CAM (Bercovitz et al., 2011). Acupuncture, chiropractic ­spinal manipulation, magnets, massage therapy, and yoga often are considered CAM pain treatments. According to the National Institutes of Health’s (NIH) National Center for Complementary and Alternative Medicine, additional CAM therapies used for pain include dietary supplements, such as glucosamine and chondroitin intended to improve joint health; various herbs; acupuncture; and mind–body approaches, such as meditation and yoga (NIH and NCCAM, 2010)."
