Despite the common use of complementary and alternative therapies for back pain, little is known about how such therapies compare with each other or with conventional medical therapies in terms of effectiveness and cost. This study will lay the groundwork for a full-scale trial that will evaluate the relative effectiveness and costs of three promising relaxation-related techniques (massage, tai chi, and meditation) that are appropriate for both younger and older adults with chronic lower back pain. The pilot study will identify and resolve unanticipated problems and estimate the sample sizes required for an adequately-powered, full-scale trial.
