Back pain is one of the most common of all symptoms. It is also a great cause of days lost from work and visits to health care providers. This study will develop and evaluate an approach to low back pain that allows subjects to talk with each other and with health professionals via an Internet discussion group. Results we will look at include health behaviors, such as exercise; health status, such as pain and disability; and health care use, such as number of visits to doctors and other health care providers. Anyone 18 years old or older who lives in the United States and has ongoing Internet access can take part in the study. All subjects must have back pain and meet the eligibility criteria listed below.
