"In the first study of its kind researchers found realworld massage therapy to be an effective treatment for chronic low back pain. Niki Munk an assistant professor of health sciences in the School of Health and Rehabilitation Sciences at Indiana UniversityPurdue University Indianapolis and one of the cofirst authors of the study said that the studys findings are important given the large number of people who suffer low back pain in the U.S. Low back pain leads all disorders in years lost to disability in the U.S. Most patients improve rapidly but onethird report persistent back pain and  percent develop chronic low back pain with significant physical limitations. More than  percent of those who participated in the study experienced clinically meaningful improvements in their low back pain with disability according to Munk. The study can give primary care providers the confidence to tell patients with chronic low back pain to try massage if the patients can afford to do so Munk said. Generally massage is not covered by insurance Medicaid or Medicare. Previous studies of the effectiveness of massage were conducted in controlled research situations. In this study patients were referred by a physician to a massage therapist. The massage therapist designed and provided a series of  massages  at no cost to the patient  in a clinical treatment environment mimicking the experience of people who choose to seek massage therapy in the real world. The study also looked at different characteristics associated with patients being more likely or less likely to experience clinically meaningful change from massage. Among the studys findings Adults in the babyboom and older generations tended to be much more likely to experience clinically meaningful changes.  Obese patients experienced significant improvements but those improvements were not retained over time.  Patients who were taking opioids experienced improvements in their pain from disability in some cases but were two times less likely to experience clinically meaningful change compared to those who were not taking opioids.  While the study results are promising much more work needs to be done Munk said The fact of the matter is that chronic lower back pain is very complex and often requires a maintenancetype approach versus a shortterm intervention option. Additional investigation is needed to replicate the results of the initial study and to conduct a costbenefit analysis of massage therapy Munk said. Massage is an outofpocket cost she said. Generally people wonder if it is worth it. Will it pay to provide massage to people for an extended period of time Will it help avoid back surgeries for example that may or may not have great outcomes These are the types of analyses that we hope will result from this study. The study RealWorld Massage Therapy Produces Meaningful Effectiveness Signal for Primary Care Patients with Chronic Low Back Pain Results of a Repeated Measures Cohort Study was published online March  in the journal Pain Medicine."
